Description:

My invention relates to improvements in archery bows and has particular reference to a sight device to be mounted upon the bow.

An important object of the invention is to provide a sight device which is rigidly secured to the bow so that it will not be thrown out of alignment due to the whip of the bow when shooting.

A further object of the invention is to provide means whereby the sight is adjustable vertically and horizontally in straight lines. A further object of the invention is to provide a sight device of the above-mentioned character having vertically horizontally adjustable parts which are clamped in the selected adjusted positions by a single element. A further object of the invention is to provide a flat plate which is clamped to the bow with its surface next to the bow provided with a groove or recess to receive the head of the clamping screw which is thereby retained out of contact with the adjacent surface of the bow when the plate is applied to the bow.

A further object of the invention is to provide a device of the above-mentioned character having a slide which is vertically adjustable longitudinally of the attaching plate and a second slide which is horizontally adjustable with respect to the first slide.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a left side elevation of an archery bow showing my sight device applied thereto, Figure 2 is a similar view, upon an enlarged scale, parts broken away, Figure 3 is a rear end elevation of the sight 4C device, Figure 4 is a vertical section taken on line 4-4 of Figure 6, // Figure 5 is a front end elevation of the sight device, 4. Figure 6 is a horizontal section taken on line 6-6 of Figure 2, Figure 7 is an exploded perspective view of the sight tube and associated elements, and, Figure 8 is an end elevation of the tubular 5( body portion, viewed substantially upon the line 8-8 of Figure 1, parts removed and parts in section.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of my 5. invention, the numeral 10 designates an archery bow having an enlarged intermediate portion forming a handle II. Secured to the ends of the bow 10 is a string 12 engaging an arrow 13, to project the same.

My sight device comprises an attaching plate 14, formed of metal or the like. This attaching plate is elongated and is preferably flat. The attaching plate is provided with a longitudinal slot 15 extending throughout ihe major portion of the length of the same and terminating short of the ends of the plate. The rear face of the attaching plate is milled out to provide a longitudinal groove or recess 16, in communication with the longitudinal slot 15 and the groove or recess 16 extends beyond the ends of the slot 15 and terminates short of the ends of the attaching plate. The front face of the plate 14 is also milled out to provide a longitudinal groove or Srecess 17, in communication with the slot 15 and extending beyond the ends of this slot and terminating short of the ends of the plate 14. The grooves 16 and 17 form a web between them, having the slot 15 therein.

SMeans are provided to rigidly secure the attaching plate 14 to the bow 10, comprising Ushaped straps 18 and 19 which are adjustably secured to the longitudinal edges of the plate 14, adjacent to its opposite ends and outwardly of Sthe recesses 16 and I7 by screws 20 or the like.

The plate 14 is arranged upon the front face of the bow 10 and contacts therewith and the groove or recess 17 is next to this front face and the Ushaped straps 18 and 09 receive the bow therein.

By manipulation of the screws 20, the straps 18 and 19 and the attaching plate 14 are rigidly secured to the bow. The attaching plate 14 is also provided adjacent to its ends and outwardly of the grooves or recesses 16 and 17 with screwSthreaded openings 21 to receive pointed set screws 22, which may be adjusted so that their pointed ends will be forced slightly into the front face of the bow. These set screws and straps rigidly secure the attaching plate 14 to the bow so that i the attaching plate cannot be displaced by the whipping action of the bow when shooting.

Arranged upon the front face of the attaching plate 14 is a T-shaped rear slide 23 including a vertical head 24 and a horizontal arm 25. The Shead 24 is provided upon its rear face with a vertical tongue 26, Figures 3 and 6, which is slidably mounted in the groove or recess 17. The horizontal arm is provided upon its front face with a horizontal longitudinal groove or recess S27. The head 24 is provided with a transverse opening 28, Figures 4 and 6. The rear slide 23 is mounted upon the attaching plate 14 to be adjusted longitudinally thereof in a straight line.

Disposed forwardly of the rear slide 23 is a front slide 29, mounted within the groove of the recess 27 and the slide 29 has a longitudinal slot 30. The numeral 31 designates a clamping screw, passing through the opening 28, slot 30 and the slot 15 and this clamping screw carries a milled nut 32 and a washer 33 preferably arranged beneath this nut. The clamping screw has a flat head 34, which is *mounted within the groove or recess 16 and spaced from the face of the bow.

The slide 29 is adjustable horizontally of the arm 24 in a straight line, and the single clamping screw 13 is manipulated to permit of the vertical and horizontal adjustment of the two slides and to clamp them in the selected positions.

Rigidly secured to the free end of the slide 29 is a horizontal arm 35, disposed at a right angle thereto. This arm carries at its front end a split ring 36, having ends 37 which may be drawn together by a screw 38. The split ring is provided with an inwardly projecting lug 36'.

At its rear end, the arm 35 carries a continuous ring 39, having radial screw-threaded openings 40, to receive adjustable centering screws 41.

A tube sight is provided, including a tubular body portion 42, adapted. for insertion within the split ring 36 and the ring 39. The tubular body portion is provided with a transverse slot or recess 42', to receive the lug 36', whereby the tubular body portion 42 Is positively held against relative longitudinal movement due to the whip action of the bow. The screws 41 are adjustable to adjust or center the tubular body portion 42 which may be clamped within the split ring 36.

Disposed at the front end of the tubular body portion 42 is a ring 43, carrying a pin 44 provided with a bead 45. The ring 43 is clamped 4 to the front end of the tubular body portion 42 by a ring-cap 46, having screw-threaded engagement with the end of the tubular body portion 42. At the rear of the tubular body portion 42 is a disk 47 which is clamped to the 4 tubular body portion 42 by a ring-cap 48 having screw-threaded engagement with the tubular body portion and the disk 47 has a sight opening 49, as shown.

As shown in the drawing, the arm 35 and tube sight are disposed upon the left side of the bow 10, although they may be disposed upon the right side, which can be readily effected by inverting the attaching plate 14 and parts carried thereby.

With the parts assembled as shown In the draw- 5 ing, the adjustment of the tube sight with respect to the arm 35 is effected by manipulation of the split ring 36 and screws 41 and the tube sight is clamped in the selected adjusted position with respect to the arm 35. By loosening n the nut 32 the two slides 23 and 29 may be adjusted vertically as a unit, while the slide 29 may be adjusted horizontally with respect to the slide 23. By tightening up the nut 32 the two slides 29 and 23 are clamped together and the rear 6o slide 23 is clamped to the attaching plate 14.

The screw 31 is therefore common to both slides.

Since the head 34 of the screw works within the groove or recess 16 this head is out of contact with the adjacent face of the bow and hence 7( there is no binding action between the head and the bow to prevent the vertical adjustment of the slide 23. The attaching plate 14 being flat and not arched, the same may be securely clamped to the bow so that it will not be dis- 75 placed due to the whipping action of the bow when shooting. The tubular sight can be adjusted with respect to the bow to meet sighting requirements of the archer under the conditions of use with respect to the target, windage, etc. The adjustment of the tube sight is effected in straight lines both vertically and horizontally.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
