HTM direct drive and positive positioning cross slide and pin housing system

[0002] 1. Field of Invention

[0003] This invention relates to an archery bow sight, specifically to an improved positive positioning windage system.

[0004] 2. Discussion of Prior Art

[0005] The Archer using a horizontal and vertical adjusting system, with attached lens holder, has round rod windage systems. This system makes it difficult to accurately locate 90° to the horizontal drive system. In addition, the pin sight housing attaches to the cross slide system with a threaded rod which, after continuous use, can break due to vibration.

[0006] Accordingly, several objects and advantages of the present invention are:

[0007] a) a cross slide system that can only position parallel and perpendicular to the vertical drive sight system;

[0008] b) a direct drive system that eliminates any unwanted windage movement;

[0009] c) a clamping windage system that securely locates and locks all systems into desired position;

[0010] d) a sight lens and pin housing system that attaches to the cross slide system and is automatically located parallel to the vertical drive systems thus eliminating all adjustment error;

[0011] e) a sight lens and pin housing system that has a machined flat slot. The bottom and sides of the slot attaches to the flat end of the cross slide system and is securely locked into position by a flat head screw; and

[0012] f) a sight lens and pin housing system that holds a sight lens which is clamped into position by a rubber “O” ring.

Sight lens 22 (FIG. 6) fits into the housing 26 (FIG. 6). Rubber lens retainer 20 (FIG. 6) presses into a groove in the housing 26 (FIG. 6) and retains sight lens into the housing 26 (FIG. 6).

[0044] A 10-32×1-½″ threaded rod 40 (FIG. 6) screws into the vertical adjustment locking knob 44 (FIG. 6) and is secured into position by a 6-32×{fraction (3/16)}″ set screw (FIG. 6). Spring 38 (FIG. 6) slides onto rod 40 (FIG. 6) and recesses into knob 44 (FIG. 6). The vertical locking knob assembly 38, 40, 42 and 44 (FIG. 6) pass through bracket assembly 56, 58 and 60 (FIG. 6) and hold the windage assembly which include 46, 48, 50, 52 and 54 (FIG. 6) and the sight housing assembly 20, 22, 24, 26, 28, 30 and 62 (FIG. 6) and the windage locking knob assembly 32, 34 and 36 (FIG. 6) and are attached to the vertical sight housing assembly bracket shown in FIGS. 1, 2 and 3. In addition, a machined flange on bracket 56 (FIG. 6) locates the complete cross slide assembly parallel and perpendicular to the vertical sight housing assembly (FIGS. 1, 2 & 3).

[0045] The windage holding bracket 56 (FIG. 4) with a machined flange is manufactured out of anodized aluminum, stainless steel or titanium, holds the cross slide windage system to the vertical sight housing assembly bracket shown in FIGS. 1, 2 and 3. The stainless steel yardage indicator marker 58 (FIG. 6) slides in and out of the windage holding bracket 56 (FIG. 6) which provides ample amount of adjustment if marker 58 (FIG. 6) has to be moved. A 4-40×{fraction (3/16)}″ stainless steel nylon tipped set screw 60 (FIG. 6) locks marker into place.

[0046] A stainless steel 10-32×1-½″ threaded rod 40 (FIG. 6) screws into the vertical adjustment locking knob 44 (FIG. 6) and is secured with a stainless steel 6-32×{fraction (3/16)}″ set screw 42 (FIG. 6). This assembly slides through a one inch long stainless steel retention spring 38 (FIG. 6) and recess into locking knob 44 (FIG. 6). The assembly continues and passes through the windage holding bracket 56 (FIG. 6) and locks the windage system to the vertical sight housing assembly bracket shown in FIGS. 1, 2 and 3.

[0047] The short threaded end of the brass double ended 10-32×2-½′ windage adjustment screw 54 (FIG. 6) screws into an anodized aluminum windage adjustment knob 50 (FIG. 6) and is locked into position with a 6-32×{fraction (3/16)}″ set screw 52 (FIG. 6). This creates the windage screw assembly 50, 52 and 54 (FIG. 6). Knob 50 (FIG. 6) has a knurled diameter, and the face of the knob 50 (FIG. 6) has “V” grooves. When assembled into the windage cross slide rod 46 (FIG. 6) the grooves on knob 50 (FIG. 6) create a clicking sound that indicates the amount of desired windage movement. The anodized aluminum or titanium rod 46 (FIG. 6) has an 8-32×{fraction (3/16)}″ ball plunger 48 (FIG. 6) recessed into one end. The ball plunger 48 (FIG. 6) protrudes outward to create the clicking sound when rotating against the “V” grooves located on the face of knob 50 (FIG. 6). Rod 46 (FIG. 6) is machined beyond the center point of the diameter and approximately 90% of its length. The purpose of the machined surface located on rod 46 (FIG. 6) is to guarantee 90° positioning. A slotted groove is machined into the side of rod 46 (FIG. 6) located near the ball plunger 48 (FIG. 6). The protruding ring located on the screw 54 (FIG. 6) and assembled parts screw 52 and screw 54 (FIG. 6) slide into the groove located on rod 46 (FIG. 6). The screw 54 (FIG. 6) is then securely positioned within rod 46 (FIGS. 4 and 6).

[0048] Windage holding bracket 56 (FIG. 5) has a through 10-32 threaded hole. This threaded hole holds the 10-32×2-½″ windage adjustment screw 54 (FIGS. 5 and 6). A machined slot located on the bracket 56 (FIGS. 5 and 6) which rod 46 (FIGS. 5 and 6) passes through. The slot located on bracket 56 (FIGS. 5 and 6) is machined with a half moon radius and perpendicular surface (FIG. 5). When the windage screw assembly 50, 52 and 54 screws into bracket 56 (FIG. 6) it pulls the rod 46 (FIG. 6) through or back out depending on the direction of knob 50, creating a positive positioning system.

[0049] An 8×32×1″ set screw 36 (FIG. 6) screws into the windage locking knob 34 (FIG. 6) and is locked into position by a 6-32×{fraction (3/16)}″ set screw 32 (FIG. 6). This assembly then screws into bracket 56 (FIG. 6) and locks rod 46 (FIG. 6) into position.

[0050] An anodized aluminum sight lens and pin housing 26 (FIG. 6) has a level 28 (FIG. 6) and a TruGlo® sight pin 62 (FIG. 6). The sight pin passes through the housing into place, and is parallel to the machined slot. The sight is held into position by two 4-40×⅛″ set screws 30 (FIG. 6). Housing 26 encases sight lens 22 (FIG. 6) and the lens 22 (FIG. 6) is retained by a rubber lens retainer 20 (FIG. 6). The rubber lens retainer 20 (FIG. 6) presses into a machined groove located on the inside rim of housing 26 (FIG. 6). Housing 26 (FIG. 6) has a machined slot 90° to the level and parallel to the sight pin. The slot in the housing is attached to the end of rod 46 (FIG. 6) and is secured and retained by the lens holder retaining screw 24 (FIG. 6). The vertical slot in housing 26 and vertical surface on rod 46 create positive perpendicular and vertical positioning for the sight pin and housing of the bow sight.

[0051] Accordingly, the HTM Direct Drive and Positive Positioning Cross Slide and Pin Housing System provides a direct drive system that eliminates any unwanted windage movement. Furthermore, the system as the additional advantages in that:

[0052] The system can only position parallel and perpendicular to the vertical drive sight system;

[0053] The clamping windage system securely locates and locks all systems into desired position;

[0054] The sight lens and pin housing system attaches to the cross slide system and is automatically located parallel and perpendicular to the vertical drive systems, thus eliminating all adjustment error;

[0055] The sight lens and pin housing system has a machined flat slot. The bottom and sides of the slot attaches to the flat end of the cross slide system and is securely locked into position by a flat head screw; and

[0056] The sight lens and pin housing system holds a sight lens which is clamped into position by a rubber “O” ring.

[0057] Although the description above contains many specifics, those should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention.

[0058] Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
