DETAILED DESCRIPTION OF THE DISCLOSURE

For the purposes of promoting an understanding of the principles of the disclosure, reference is now made to the embodiments illustrated in the drawings and particular language will be used to describe the same. It is understood that no limitation of the scope of the claimed subject matter is intended by way of the disclosure.

The terms “first,” “second,” “third,” and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

As used herein, the terms “may” and “may be” indicate a possibility of an occurrence within a set of circumstances; a possession of a specified property, characteristic or function; and/or qualify another verb by expressing one or more of an ability, capability, or possibility associated with the qualified verb. Accordingly, usage of “may” and “may be” indicates that a modified term is apparently appropriate, capable, or suitable for an indicated capacity, function, or usage, while taking into account that in some circumstances, the modified term may sometimes not be appropriate, capable, or suitable. For example, in some circumstances, an event or capacity can be expected, while in other circumstances, the event or capacity cannot occur. This distinction is captured by the terms “may” and “may be.”

In regard to the use of a term in this disclosure in the singular and/or plural, persons of ordinary skill in the art can translate such term(s) from the singular to the plural and/or from the plural to the singular in accordance with the context of the disclosure. The inclusion of “(s)” after an element or a step indicates that one or more than one of such element or step is present with the understanding that each thereof is an independent aspect of the disclosure.

Terms and phrases used in this document, and variations thereof, unless otherwise expressly stated, should be construed as open-ended as opposed to limiting. As examples of the foregoing: the term “including” should be read as meaning “including, without limitation” or the like, the term “example” is used to provide exemplary instances of the item in discussion, not an exhaustive or limiting list thereof, the terms “a” or “an” should be read as meaning “at least one,” “one or more,” or the like. The use of the term “assembly” does not imply that the components or functionality described or claimed as part of an assembly are all necessarily configured in a common package.

It is to be understood that the present disclosure is not limited to particular embodiments. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting. Herein, the term “optical sight” may be used interchangeably with the terms “scope,” “scope sight,” “optical platform,” “sight system,” “telescopic sight,” “optical aiming device,” and “viewing optic.” Herein, a person using a turret system of this disclosure may be referred to as a “user,” “operator” or “shooter.”

Herein, the term “dot” need not necessarily be provided in a circular or substantially circular form.

Herein, “MIL” or “MRAD” is a shortening of the term milliradian and “MILs” and “MRADs” is a shortening of milliradians. A milliradian is an angular measurement wherein a milliradian is a thousandth of a radian. There are 6,283 radians in a circle, which equates to 6283.0 milliradians in a circle. As understood by the skilled artisan, milliradians are used in the adjustment of firearm sights by adjusting the angle of a sight compared to the barrel of a corresponding firearm. For purposes of this disclosure, “milliradian,” “MIL” and “MRAD” can be used interchangeably.

Herein, “MOA” refers to Minutes of Angle, which is an angular measurement wherein one minute of angle is equal to 1/60 of a degree. As understood by the skilled artisan, the term “subtension” refers to the amount of a target that is covered by some part of a reticle of an optical sight. Subtension may be measured in length at a specific distance (inches at a distance in yards) or as an angular measurement in MRAD or MOA.

As understood by the skilled artisan in projectile launching devices, an “elevation turret” is an adjustment turret typically located on an upper part of an optical sight configured to adjust vertical alignment of a reticle of the optical sight to adjust the point of impact for bullet drop and a “windage turret” is an adjustment turret typically located on a side of an optical sight configured to adjust horizontal alignment of a reticle of the optical sight to adjust the point of impact for wind. As also understood by the skilled artisan, elevation adjustments and windage adjustments are typically measured in MRAD or MOA measurements.

As used in this specification and the appended claims, a “projectile launching device” may include, but is not necessarily limited to a firearm, a bow, and a crossbow. Herein, the term “firearm” may include, but is not limited to a pistol, a semiautomatic firearm, e.g., a semiautomatic rifle, a bolt action firearm, e.g., a bolt action rifle, a shotgun, a revolver, a shoulder fired bazooka, a shoulder fired rocket launcher, an air rifle, and a paintball gun. As understood by a person skilled in the art of firearms and/or firearm shooting (a “skilled artisan”), a particular firearm may be provided in different barrel lengths. Non-limiting examples of pistols are provided in United States Patent Number U.S. Pat. No. 4,539,889, titled “Automatic Pistol with Counteracting Spring Control Mechanism,” issued on Sep. 10, 1985; and United States Patent Number U.S. D918,328 S, titled “Handgun,” issued on May 4, 2021, each of which is herein incorporated by reference in its entirety.

Herein, the term “firearm load” refers to a unit of ammunition that includes a cartridge case, primer, powder and bullet. The term “bullet drop” refers to the curved trajectory traversed by a moving projectile, e.g., a bullet, as it falls from its initial trajectory while traveling a distance, i.e., “target range” or “target distance,” from a projectile launching device to a target. As understood by the skilled artisan, bullet drop is caused by the influence of gravity on a moving projectile or bullet. Therefore, to hit a target at long range, it is necessary to elevate the barrel of a firearm and the aiming point to compensate for bullet drop. The term “full value wind” refers to wind blowing perpendicular left to right or right to left in relation to a reticle and user thereof, e.g., a cross wind. Using a clock system, full value winds travel “9 to 3” and “3 to 9” in relation to a reticle of an optical sight and user thereof. As also understood by the skilled artisan, the term “full value” in reference to wind means that the force of the wind has a full effect on the flight of a bullet compared to a “half value wind” or “no value wind.” As further understood by the skilled artisan, generally, the greater the velocity of wind the greater its force.

Herein, “environmental contaminants” may include but are not limited to liquids, moisture, vapor, gases, reactive chemicals, and debris. Non-limiting examples of debris may include materials such as dirt, dust, sand, powdery substances, metal shavings, wood shavings, fine particulate matter, and combinations thereof.

In an embodiment, one or more cassettes 14 of a system 10 may be provided for use as both one or more elevation cassettes 14A and one or more windage cassettes 14B. In another embodiment of an optical sight 5 comprising both an elevation turret interface 12A and a windage turret interface 12B, the elevation turret interface 12A and the windage turret interface 12B may be comprised of an assembly of members of different construction whereby one or more particular cassettes 14 may be configured solely for use as elevation cassettes 14A and one or more particular cassettes 14 may be configured solely for use as windage cassettes 14B.

With reference to FIG. 7, an embodiment of a turret interface 12 of an optical sight 5 suitable for use as an elevation turret interface 12A and as a windage turret interface 12B is described here in terms of an elevation turret interface 12A configured for use with one or more elevation cassettes 14A. As shown, in an embodiment an elevation turret interface 12A may include an adjustable assembly of moveable members comprising at least a first adjustment member 20 (or “first jacking screw 20” or “primary jacking screw 20”) and a second adjustment member 22 (or “second jacking screw 22” or “secondary jacking screw 22”), each of which rotates about a rotational axis 3 of the elevation turret interface 12A and may be directed linearly along the rotational axis 3 in either direction. In an embodiment, the first jacking screw 20 may include an outer threaded surface 24 and a first end 21 comprising a contact member 26 (or “contact pad 26”), the contact pad 26 having a face 27 type surface for contacting a contact pad contact surface 8 of an adjustable member of an optical sight 5, e.g., for contacting a contact pad contact surface 8 of an erector tube of an optical sight 5. In an embodiment, a contact pad 26 may include a planar face 27 as shown. In an embodiment, a contact pad 26 may include a non-planar face 27. In an embodiment, a contact pad 26 may be removably secured to a first jacking screw 20. In an embodiment, a contact pad 26 may be permanently secured to a first jacking screw 20. In an embodiment, an elevation turret interface 12A may be provided without a contact pad 26 whereby a first end 21 of the first jacking screw 20 may be employed as a contact surface for contacting a contact surface 8 of an adjustable member of an optical sight 5. Herein, a contact pad 26 may also be referred to as a “jacking screw bearing flange.”

Herein, the main seat member 28 may also be referred to as a “main seat retaining ring 28.” As stated above, in an embodiment the main seat member 28 may be removably attached to an optical sight 5 via the threaded connection between the inner threaded surface 7 of the main body 6 of an optical sight 5 and the outer threaded surface 32 of the main seat member 28. In another embodiment, a main seat member 28 may be permanently affixed to the optical sight 5, e.g., permanently affixed by applying one or more adhesives as known in the art of optical sights between the outer threaded surface 32 of the main seat member 28 and the inner threaded surface 7 of the main body 6 of the optical sight 5 providing a continuous or partially continuous seal there between. In an embodiment, one or more fasteners, for example, one or more threaded fasteners and/or non-threaded fasteners, e.g., one or more locking pins, may be used alone or in addition to one or more adhesives to permanently affix the main seat member 28 to the optical sight 5. In an embodiment, an elevation turret interface 12A may be configured to environmentally seal one or more internal components of the elevation turret interface 12A and the interior of an optical sight 5 from one or more environmental contaminants independent of any elevation cassettes 14A being removably attached thereto. One or more environmental seals of an elevation turret interface 12A may be formed via the abutment or contact between one or more components and/or via one or more sealing members disposed at one or more points along the elevation turret interface 12A, e.g., see sealing members 140, 141 and 142 in FIG. 11. Suitable sealing members may include, but are not limited to one or more gaskets, O-rings, and combinations thereof. One or more sealing members may also be disposed at one or more other points along an elevation turret interface 12A, e.g., see space 149 between the main seat member 28 and the main body 6 of an optical sight 5 in FIG. 11.

Still referring to FIG. 7, in an embodiment a cylindrical portion 29 of the main seat member 28 may include an inner threaded surface 35 for threaded communication with an outer threaded surface 38 of a second jacking screw sleeve lock ring 37 of an annular sleeve member 40 (or “second jacking screw sleeve 40”), the second jacking screw sleeve 40 having a cylindrical portion 41 and an annular ring portion 42. As shown, in an embodiment the second jacking screw sleeve 40 may include a cylindrical portion 41 having an inner threaded surface 44 for threaded communication with an outer threaded surface 23 of the second jacking screw 22, the outer threaded surface 23 being disposed along or near a first end of the second jacking screw 22. As further shown, in an embodiment the elevation turret interface 12A may also include at least one locating pin 46 disposed between the cylindrical portion 29 of the main seat member 28 and the annular ring portion 42 of the second jacking screw sleeve 40. Suitably, the at least one locating pin 46 is configured as a rigid interconnect for rotationally fixing the main seat member 28 to the second jacking screw sleeve 40.

As shown in FIG. 7, in an embodiment the elevation turret interface 12A may also include an annular main shaft member 47 (or “main shaft 47”) fixedly engaged with the annular retaining ring portion 30 of the main seat member 28. In an embodiment as shown, the main shaft 47 may be disposed between the annular retaining ring portion 30 of the main seat member 28 and the second jacking screw sleeve 40 in a manner effective whereby the main shaft 47 may be turned about the rotational axis 3 for operation with a click ring 50 of the elevation turret interface 12A as described below. In an embodiment, the main shaft 47 may include a circular disc type section 48 and a cylindrical section 49 as shown. In an embodiment, the cylindrical section 49 defines an opening coaxial with the rotational axis 3 wherein the cylindrical section 49 has an inner splined surface 52 for receiving an outer splined surface 36 of the first jacking screw 20 in a mated position as shown. In an embodiment, the cylindrical section 49 may also include an outer splined surface 53 configured to operably communicate with an inner splined surface 25 of the second jacking screw 22. As such, in an embodiment the first jacking screw 20 may be rotatably coupled to the second jacking screw 22 via the main shaft 47.

Stiff referring to FIG. 7, in an embodiment a click ring 50 may be press fit and/or glued and/or threaded into the main seat member 28. As shown, in an embodiment a corresponding plunger (or “click pin 55” or “click detent 55”) may be located in a radial borehole 56 of the disc type section 48 of the main shaft 47 along with at least one biasing member 58 that is configured to bias the click detent 55 radially outward to an abutment position with the click ring 50 along the length of the inner perimeter of the click ring 50 as the main shaft 47 is turned about the rotational axis 3. In an embodiment, the at least one biasing member 58 may include at least one coiled spring (or “detent spring”).

As shown in FIGS. 8 and 9, in an embodiment the inner surface of a click ring 50 may include a plurality of ridges and grooves 51 for receiving a distal end 59 of a click detent 55 between adjacent ridges of the ridges and grooves 51. In an embodiment, a distal end 59 of a click detent 55 may include a planar end type surface as shown in FIG. 7. As shown in FIG. 9, in another embodiment a distal end 59 of a click detent 55 may include a tapered surface, e.g., wedge shape and/or the like, configured to promote linear movement of the click detent 55 within the radial borehole 56 as the distal end 59 rides over the ridges and grooves 51 of the click ring 50 in both a clockwise and counterclockwise direction. In an embodiment, a click ring 50 and click detent 55 may cooperate to provide audible and tactile clicks as the elevation turret interface 12A is turned, e.g., as the elevation turret interface 12A is turned via an attached cassette 14 alone or in combination with a turret cap 16 attached to the cassette 14. At a resting position, the distal end 59 of the click detent 55 is biased between adjacent ridges in a particular groove of the ridges and grooves 51. Without limiting the disclosure to a particular number of clicks per rotation, in one suitable embodiment a click ring 50 may include a number of ridges and grooves 51 providing one hundred clicks per 360.0 degrees rotation of the elevation turret interface 12A.

Referring again to FIG. 7, in an embodiment a second jacking screw 22 may include one or more mounting surfaces at or near a second end of the second jacking screw 22 configured to receive each of the one or more elevation cassettes 14A in an operable mated position effective to provide an elevation turret assembly 11A of an optical sight 5. As shown, in an embodiment the one or more mounting surfaces may include at least (1) an outer tapered or outer conical surface 60 and (2) an outer indexing surface 62 (shown as an outer “splined surface 62” comprising a plurality of splines) near or adjacent the outer conical surface 60, wherein the outer conical surface 60 and the outer splined surface 62 are coaxial to rotational axis 3 and configured as a mounting interface for receiving an elevation cassette 14A in operable attachment thereto as described below. As also described below, each individual elevation cassette 14A of a system 10 configured for use with an elevation turret interface 12A as shown in FIG. 7 may include one or more common mating surfaces corresponding to the one or more mounting surfaces of the second jacking screw 22 for removable attachment of each of the one or more elevation cassettes 14A to the elevation turret interface 12A.

With reference to FIG. 10, in an embodiment an elevation cassette 14A (see elevation cassette 14A-A) of a system 10 may include at least (1) an inner tapered or inner conical surface 17A configured as a mating surface for mating in an abutment position with an outer conical surface 60 of a second jacking screw 22 and (2) an inner indexing surface 18A such as an “inner splined surface 18A” configured as a mating surface for mating with an outer splined surface 62 of a second jacking screw 22 when the elevation cassette 14A-A is operably attached to a second jacking screw 22 as shown in FIGS. 11 and 12. In an embodiment as shown in FIGS. 11 and 12, the inner conical surface 17A and the inner splined surface 18A may be configured as a mating interface of an elevation cassette 14A-A, wherein when the elevation cassette 14A-A is operably attached to the second jacking screw 22 then the inner conical surface 17A and the inner splined surface 18A are coaxial to the rotational axis 3.

As described below, in an embodiment one or more individual elevation cassettes 14A of a system 10 may include an inner conical surface the same or substantially the same as an inner conical surface 17A and an inner splined surface the same or substantially the same as an inner splined surface 18A as shown in FIG. 10. In another embodiment, one or more individual elevation cassettes 14A of a system 10 may include only an inner conical surface the same or substantially the same as inner conical surface 17A for mating with an outer conical surface 60 without the inclusion of an inner splined surface the same or substantially the same as inner splined surface 18A. In another embodiment, one or more individual elevation cassettes 14A of a system 10 may include only an inner splined surface the same or substantially the same as inner splined surface 18A for mating with an outer splined surface 62 without the inclusion of an inner conical surface the same or substantially the same as inner conical surface 17A. In addition, although an outer splined surface 62 of a second jacking screw 22 and an inner splined surface 18A of an elevation cassette 14A-A may be cylindrical in shape as depicted, in another embodiment the outer splined surface 62 and corresponding inner splined surface 18A may include one or more other configurations, e.g., one or more non-cylindrical multi-sided outer and inner surface configurations.

With reference to FIG. 11, in an embodiment an inner conical surface 17A of an elevation cassette 14A-A may form an angle relative the rotational axis 3 that is the same or substantially the same as the angle of the outer conical surface 60 of the second jacking screw 22 allowing the male type outer conical surface 60 to receive the female type inner conical surface 17A in a mated position effective to maximize the surface contact between the inner conical surface 17A and the outer conical surface 60 as shown in FIG. 11, which depicts an outer conical surface 60 contacting the full surface of the inner conical surface 17A. As FIG. 11 depicts, in an embodiment the outer conical surface 60 may include a length greater than the length of the corresponding inner conical surface 17A. In another embodiment, an outer conical surface 60 and a corresponding inner conical surface 17A may comprise the same or substantially similar lengths. In an embodiment, an elevation turret interface 12A may be configured so that the outer conical surface 60 has a length less than the length of the corresponding inner conical surface 17A. Although not limited to a particular tapered angle, in an embodiment of an elevation turret interface 12A as shown in FIG. 7 the outer conical surface 60 may have a tapered angle θ1 from or about 5.0 degrees to or about 30.0 degrees. In an embodiment, the outer conical surface 60 may have a tapered angle θ1 of or about 15.0 degrees (see FIG. 13).

Referring again to FIG. 7, in an embodiment the second end of the second jacking screw 22 may further include a female mating surface 64 configured to receive a primary fastener 65 therein in a manner effective to removably attach an elevation cassette 14A such as elevation cassette 14A-A to an elevation turret interface 12A as shown in FIG. 11 or removably attach an elevation cassette 14A such as elevation cassette 14A-A and a turret cap 16A to an elevation turret interface 12A as shown in FIG. 12 providing an elevation turret assembly 11A of an optical sight 5. In an embodiment, a female mating surface 64 may be provided as a threaded female surface as shown configured to receive therein a threaded primary fastener 65. In an embodiment, a female mating surface 64 may be provided as a non-threaded surface configured to receive a primary fastener 65 such as a non-threaded primary fastener 65, e.g., a pin, a key, therein. In an embodiment, elevation turret interface 12A may be configured for removably attaching an elevation cassette 14A thereto via one or more retaining rings, clips, springs, washers, clamps, push-lock fittings, press-lock fittings, and combinations thereof. For purpose of illustration, a female mating surface 64 is discussed below as a female threaded surface for receiving a threaded primary fastener 65 therein.

In an embodiment, when attaching an elevation cassette 14A such as elevation cassette 14A-A to a second jacking screw 22, a primary fastener 65 of the elevation turret interface 12A may be removed from the second jacking screw 22 and then the elevation cassette 14A-A may be axially aligned with the second jacking screw 22 so that the inner splined surface 18A of the elevation cassette 14A-A is oriented in a manner effective to mate with the outer splined surface 62 as the elevation cassette 14A-A is directed linearly onto the second jacking screw 22 (see directional arrow 1A) to a mated position as shown in FIG. 11. Suitably, the outer splined surface 62 and corresponding inner splined surface 18A provide for angular indexing of an elevation cassette 14A such as elevation cassette 14A-A, and a turret cap 16A attached thereto, allowing an elevation cassette 14A, and a turret cap 16A attached thereto, to be accurately and repeatedly oriented about an elevation turret interface 12A of an optical sight 5 as desired when being set to a mated position with an elevation turret interface 12A.

Once an elevation cassette 14A such as elevation cassette 14A-A is set to a desired mated position with a second jacking screw 22, a primary fastener 65 may be threaded through the elevation cassette 14A-A into the female mating surface 64 toward the second jacking screwing 22 (see directional arrow 1A in FIG. 7) wherein a force (see vector arrow V1 in FIG. 11) is applied to an annular outer contact surface 70 of the elevation cassette 14A-A via the inner surface 67 of the head 66 of the primary fastener 65, which generates friction between the inner conical surface 17A of the elevation cassette 14A-A and the outer conical surface 60 of the second jacking screw 22 wherein the coefficient of friction between the inner conical surface 17A and the outer conical surface 60 is sufficient to maintain the inner conical surface 17A in a fixed position with the outer conical surface 60 during operation of turret assembly 11A. Suitably, a force applied to an annular outer contact surface 70 of an elevation cassette 14A-A as described above is sufficient for turret assembly 11A operation while also allowing for ease of disassembly of the elevation cassette 14A-A from an elevation turret interface 12A.

Referring to FIG. 11, in an embodiment of a second jacking screw 22 comprising both an outer conical surface 60 and an outer splined surface 62 the inclusion of and mating between an outer splined surface 62 and an inner splined surface the same or substantially the same as inner splined surface 18A of elevation cassette 14A-A is configured to assist in maintaining a fixed position of the inner conical surface 17A against the outer conical surface 60 during operation of turret assembly 11A. A fixed position between an outer conical surface 60 and an inner conical surface 17A, alone or in addition to the splined communication between the outer splined surface 62 and inner splined surface 18A, is effective to maintain an angular orientation of an elevation cassette 14A with an elevation turret interface 12A during operation as a turret assembly 11A.

In an embodiment, the one or more mounting surfaces of a second jacking screw 22 may include an outer conical surface 60 as shown in FIG. 7 without inclusion of a cylindrical outer splined surface 62 for receiving in operable attachment an embodiment of an elevation cassette 14A comprising at least an inner conical surface the same or substantially the same as inner conical surface 17A. In an embodiment, the one or more mounting surfaces of a second jacking screw 22 may include a cylindrical outer splined surface 62 without inclusion of an outer conical surface 60 for receiving in operable attachment an embodiment of a corresponding elevation cassette 14A having at least an inner splined surface the same or substantially the same as inner splined surface 18A.

In an embodiment, a second jacking screw 22 of an elevation turret interface 12A may include one or more mounting surface configurations other than the one or more mounting surfaces as shown in FIG. 7. In an embodiment, an elevation turret interface 12A of this disclosure may include one or more components permanently attachable or removably attachable to a second jacking screw 22 including one or more components configured as or providing one or more mounting surfaces of the elevation turret interface 12A.

As shown in FIG. 7, in an embodiment an elevation turret interface 12A may also include one or more thread inserts 68 in threaded communication with threads of a female mating surface 64. An example of a thread insert 68 for use as part of an elevation turret interface 12A may include, but is not limited to a HELICOIL® thread insert available from Böllhoff Inc., Kendallville, Indiana, U.S.A. (on the world wide web at www.boellhoff.com). In an embodiment, one or more thread inserts 68 may be permanently attached to the female mating surface 64 of the second jacking screw 22. In an embodiment, one or more thread inserts 68 may be removably attached to the female mating surface 64 of the second jacking screw 22.

Again, a turret assembly 11A, 11B of this disclosure may operate via an elevation cassette 14 without a turret cap 16 or a turret assembly 11A, 11B of this disclosure may operate via a combination of an elevation cassette 14 and a turret cap 16. In an embodiment of a turret assembly 11A as shown in FIG. 11, an elevation cassette 14A-A is configured as a manually operable control member of the turret assembly 11A. In an embodiment of a turret assembly 11A as shown in FIG. 12, a turret cap 16A is configured as a manually operable control member of the turret assembly 11A. In an embodiment of a turret assembly 11A and/or 11B including a turret cap 16, the turret assembly 11A and/or 11B and turret cap 16 attached thereto may be configured to provide an environmentally seal from one or more environmental contaminants, e.g., see sealing member 143 in FIG. 11.

As shown in FIG. 12, in an embodiment a turret cap 16 such as turret cap 16A may include a closed cover 72 and a cylindrical sidewall 73 extending out from the perimeter of the cover 72 enveloping or otherwise covering all or substantially all of the components of the elevation turret interface 12A when the turret cap 16A is assembled with an elevation cassette 14A-A and an elevation turret interface 12A in an operable position as shown. In an embodiment, the sidewall 73 may include one or more radially disposed threaded apertures 74 for receiving a threaded fastener 75 (or “turret cap set screws 75”) through at least one of the one or more one or more radially disposed threaded apertures 74 in a manner effective to fix the turret cap 16A to the elevation cassette 14A-A to promote rotation of the elevation cassette 14A-A, the first jacking screw 20 and the second jacking screw 22 when the turret cap 16A is directed clockwise and counterclockwise about the rotational axis 3. In an embodiment, an elevation cassette 14A such as elevation cassette 14A-A may include one or more abutment surfaces or mating surfaces for each of the one or more turret cap set screws 75. As shown in FIG. 12, an elevation cassette 14A-A may include an outer perimeter surface including one or more outer tapered surfaces 78 configured as one or more abutment surfaces for each of the one or more turret cap set screws 75 whereby the one or more turret cap set screws 75 apply a force (see vector arrow V2) to the one or more tapered surfaces 78 effective to hold the turret cap 16A in a fixed position relative to the elevation cassette 14A-A during operation of the turret assembly 11A. In an embodiment, the one or more turret cap set screws 75 may include one or more “cone point set screws” and/or the like as understood by the skilled artisan comprising conical distal ends 76 configured to abut the one or more tapered surfaces 78 of the elevation cassette 14A-A as shown.

As described above, and said another way, in an embodiment as shown in FIG. 7 a cylindrical section 49 of the main shaft 47 may be keyed to the first jacking screw 20 and the second jacking screw 22 via a splined communication configuration and the second jacking screw 22 may be rotatably communicated with an elevation cassette 14A via a mating of the one or more mounting surfaces of the elevation turret interface 12A with the one or more mating surfaces of the elevation cassette 14A as described above. In addition, as also described above, a turret cap 16A may be communicated with an elevation cassette 14A via the one or more turret cap set screws 75. Accordingly, in operation turning of the turret cap 16A about the rotational axis 3 directs turning of the elevation cassette 14A, the second jacking screw 22, the main shaft 47 and the first jacking screw 20 about the rotational axis 3.

With reference to FIGS. 11 and 12, in an embodiment a turret assembly 11A of this disclosure may include variation in thread pitch between the first jacking screw 20, which is defined by a first thread pitch, and the second jacking screw 22, which is defined by a second thread pitch. In other words, the first jacking screw 20 may be configured to move linearly in either direction along the rotational axis 3 when turned about the rotational axis 3, e.g., move linearly in an “up-and-down” direction according to directional arrow 2A (see FIG. 7) at a different rate than the second jacking screw 22. In an embodiment, metric thread sizes may be employed, i.e., according to the distance between adjacent thread crests. In an embodiment, inch thread sizes may be employed, i.e., according to the number of threads per inch. In an embodiment, the thread pitch of the first jacking screw 20 may be determined by the angular travel of the optical system configuration of the corresponding optical sight 5, i.e., the click value and clicks per rotation between a click ring 50 and a click detent 55 may be determined by the angular travel of the optical system configuration of the corresponding optical sight 5. In an embodiment, the thread pitch of the second jacking screw 22 may be a set value. In such an embodiment, the first jacking screw 20 may vary in overall size, but the thread pitch of the second jacking screw 22 is suitably a set value effective to standardize the rate of linear travel of an elevation cassette 14A-A of a system 10, e.g., as shown in FIG. 11, or an elevation cassette 14A-A and turret cap 16A combination of a system 10, e.g., as shown in FIG. 12. In an embodiment, a first jacking screw 20 and a second jacking screw 22 may have the same or a substantially similar thread pitch.

For purpose of discussion, the disclosure may be described in terms of a second jacking screw 22 having a thread pitch of 1.0 mm. In such an embodiment, a second jacking screw 22 and an elevation cassette 14A attached thereto raise and lower 1.0 mm per 360.0 degrees rotation (or “full rotation”) of the elevation cassette 14A. Referring to FIG. 12, in an embodiment the second jacking screw 22, the elevation cassette 14A-A and turret cap 16A attached thereto raise and lower 1.0 mm per 360.0 degrees rotation (or “full rotation”) of the elevation cassette 14A-A and the turret cap 16A. In an embodiment where the thread pitch of the second jacking screw 22 is a set value as described above, a turret assembly 11A of this disclosure may be used across different optical platforms regardless of the thread pitch of the first jacking screw 20.

In an embodiment, linear travel of the first jacking screw 20 and the second jacking screw 22 along the rotational axis 3 may terminate at the same moment during turret assembly 11A operation. For example, in a non-limiting embodiment where the first jacking screw 20 has a thread pitch of 2.0 mm, the second jacking screw 22 has a thread pitch of 1.0 mm and the overall travel of the turret assembly 11A is 5.0 mm, the first jacking screw 20 is configured to rotate 2.5 full rotations, meaning that the overall linear travel of the second jacking screw 22 is limited to 2.5 mm up-and-down (see directional arrow 2A in FIG. 7). FIG. 14 illustrates a first jacking screw 20 and a second jacking screw 22 of an elevation turret interface 12A set at a first uppermost travel position. FIG. 15 illustrates a first jacking screw 20 and a second jacking screw 22 of an elevation turret interface 12A set at a second intermediate travel position. FIG. 16 illustrates a first jacking screw 20 and a second jacking screw 22 of an elevation turret interface 12A set at a third lowermost travel position. A second intermediate travel position of a first jacking screw 20 and a second jacking screw 22 is not limited to the travel position as shown in FIG. 15 and may include one or more other travel positions of a first jacking screw 20 and a second jacking screw 22 set at points between a first uppermost travel position and a third lowermost travel position. As understood by the skilled artisan, in an embodiment the thread pitch of the second jacking screw 22 may be modified, e.g., modify the thread dimensions of the second jacking screw 22, modify a multi-start thread configuration of a second jacking screw 22, to ensure a desired overall linear travel of the second jacking screw 22 during operation of a turret assembly 11A.
