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

Description:
BACKGROUND 
     1. Field of Invention 
     This invention relates to an archery bow sight, specifically to an improved positive positioning windage system. 
     2. Discussion of Prior Art 
     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. 
     OBJECTS AND ADVANTAGES 
     Accordingly, several objects and advantages of the present invention are: 
     a) a cross slide system that can only position parallel and perpendicular to the vertical drive sight system; 
     b) a direct drive system that eliminates any unwanted windage movement; 
     c) a clamping windage system that securely locates and locks all systems into desired position; 
     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; 
     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 
     f) a sight lens and pin housing system that holds a sight lens which is clamped into position by a rubber “O” ring.

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  &amp;  3 ). 
     OPERATION—FIGS.  1  to  6   
     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. 
     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 . 
     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 ). 
     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. 
     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. 
     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.
