ARCHERY BOW SIGHT 2 Sheets-Sheet 2 INVENTOR.

[On 0RD J Z/fLl/VSK/ V/LQM ATTOR/Vf) United States Patent Patented Sept. 5, 1961 ice This invention relates to archery bow sights and more particularly pertains to a sight device having an adjustable mounting and movable, adjustable and reversable sight pins for selectively mounting movable sights of different types in multiple.

Bow'sights have been employed heretofore to facilitate the sighting of the bow at different ranges through diiferent visual sights means. However, the several devices of the prior art have not proven entirely satisfactory inasmuch as they are unsatisfactory in design and construction, do not provide adequate facility in use, and are not sufliciently adjustable to be suitable for the archer under all conditions.

With the foregoing in view, the primary object of the invention is to provide a bow sight which is adequate in design and construction, highly adjustable and variable, and which provides multiple mounts for multiple bow sights thereby rendering the device completely suitable for the archer under all conditions.

An object of the invention is to provide a bow sight having a lineal slide bar track aligned with the bow and. a sliding carriage block adjustably disposed thereon for elevational adjustment relative to the track and bow.

An object of the invention is to provide multiple transverse apertures in the sliding block for supporting sights thereon elevationally adjustablewith the block.

An object of the invention is to provide a jam-head in the block having apertures aligned with the block apertures for receiving the sight supporting pins'therein for the purpose of'binding the pins in their laterally adjusted position.

An object of the invention is to provide a transverse aperture in the block and jam-head for reversably receiving at the supporting pins therein from either side of the device so as to selectively support the sight on either side of the bow.

An object of the invention isto provide multiple sight supporting means on the slide block for supporting multiple sights on either or both sides of the track and bow.

An object of the invention is to provide a friction spring positioning and holding the block in the adjusted position relative to the slide track.

An object of the invention is to provide an index arm on the sliding block for co-operation with a yardage index scribed on a bow.

An object of the invention is to provide a threaded aperture in the slide block and a threaded sight supporting pin therethrough which is adjustable for axial projection by rotating the threaded pin relative to the threaded block aperture.

These and other objects of the invention will become apparent by reference to the following description of a bow sight embodying the invention taken in connection with the accompanying drawings in which:

FIG. 1 is a side elevational view of the bow sight mounted on a bow.

FIG. 2 is a face elevational view, greatly enlarged, of a section of FIG. 1 showing the integration and structure of the sight.

FIG. 3 is a cross sectional view of FIG. 2 taken on the line 3--3 thereof.

FIG. 4 is a cross sectional view taken on the line 4-4 of FIG. 2.

disposed between the block and slide track for frictionally FIG. 5 is a cross sectional view of FIG. 3 taken on the line 5-5 thereof.

FIG. 6 is a perspective view of a section of a bow With an inventive sight device mounted thereon.

FIG. 7 is a cross sectional view of FIG. 6 taken on the line 7-7 thereof; and

FIG. 8 is a perspective view similar to FIG. 6 showing a modified slide bar track.

Referring now to the drawings wherein like numerals refer to like and corresponding parts throughout the several views, the bow sight device disclosed therein to illustrate the invention comprises, a slide bar track 10 mounted on the bow 11, a sliding block 12 mounted on the slide track 10 equipped with an index arm 13 for reading the elevational index scribed on the how, a sight supporting pin 14 supporting the ball sight 15, and paired

sight supporting pins

16 and 17 supporting the cross hair or prism sight 18.

More particularly the archery bow sight device, FIG. 6, has a multiple adjustable and reversable mount comprising the track 10 including a slide bar 20,

legs

21 and 22 on either end of the slide bar 20, and a

foot

23 and 24 on each respective leg with

feet

23 and 24 being attachable to a bow 11 with the

legs

21 and 22 spacing the bar from the how; the bar 20 has front and

back faces

25 and 26 and opposite

lineal edges

27 and 28. The'carriage 12 is slidably mounted on the track 10 and includes, FIGS. 4 and 7, a sliding block 29 having a channel '30 slidably disposed on the bar 20 defined by opposed

grooved bottom ways

31 and 32 enveloping the slide'ba'r

lineal edges

27 and 28 with the leg edges being relieved in the area33 for by-passing the block ways 31 and'32 in mounting and dismounting the block 29 and the track 10 with the block having a spring containing recess 34 above said channel and a hair-pin type leaf spring 35 disposed in the recess 34 having a first leaf 36, FIG. 3, bearing against the block 29 and a second leaf 37bearing against the bar 20 frictionally positioning the block 29 relative to the bar 20 in any lineally adjusted position; the

spring leaves

36 and 37 are interconnected by a loop portion 38 outside said block 29 a rea; a pin 39, FIG.' 5, is

disposed through the block 29 abutting the first spring leaf 36 confining it laterally against the block 29 which first spring leaf 36 has

projections

40 and 41 on either side of the pin 39 preventing lineal movement of the spring 36 relative to the block 29 rendering the spring 35 movable with the block 29 relative to the track 10', and

at least one set screw 42 in the block 29, FIG. 2, engaging the track bar 20 for mechanically fixing the block 29 on the bar 20 in any adjusted position. 7

In one embodiment, FIG. 8, one leg 21 A is reversely curved under the bar 20-A to provide added'track springwise flexing in conjunction with bow bending and to raise one end of the bar higher than the other to compensate for the bows curvature.

The block 29 has a top 5i opposite the

bottom ways

31 and 32, opposite ends, opposite sides above the ways, a central slot 55 leading upwardly through the top Sii, FIGS. 2-5, and multiple side to side transverse apertures leading through the block 29 in the area of the slot 55; the jam-head 56 is slidably disposed in the slot 55 and has apertures axially aligned with the block transverse apertures; the

sight supporting pins

14, 16, and 17 lie in the block 29 and head 56 aligned apertures; a bolt 60 is fixed on the head 56 leading through the block top 56, and a nut 57 is threaded on the bolt 60 engaging the block top 50 adapted upon tightening to develop draw force on the bolt 60 and the head 56 outwardly of the block top 50 jamming the

pins

14, 16, and 17 between the block 29 and head 56 fixing the pins relative thereto; the pins being sidewise extensably adjustable relative to the block by loosening the nut.

Preferably, the head 56 has at least one threaded aperture 14-A, FIG, 4, with the pin 14 disposed therein being matingly threaded and extensably adjustable relative to the block 29 by loosening the nut 57 and rotating the pin 14 relative to the head 56, and also preferably,

the block 29 and head 56 have at least two paired spaced aligned apertures with the paired

spaced pins

16 and 17 lying in the apertures with the visual sight means 18 interconnecting the

pins

16 and 17 exteriorly of the block 29 with the paired interconnected pins firmly supporting the sight means. The curved index arm 13 on the block 29 leads sidewise outwardly therefrom so as to project beyond a bow 11 on which the device is mounted with the arm 13 having a downwardly curving end depending below the track It so as to overlie the side of a bow 11 on which the device is mounted so as to be accurately readably relative to elevation index markings, not shown, scribed on a bow.

Preferably the block top 50 has paired side to

side surface grooves

61 and 62 and a plate 63 overlying the block top 50 under the nut 57 with the plate 63 having side to

side surface grooves

64 and 65 opposite the

block top grooves

61 and 62 forming a channel in conjunction therewith; the sight means supporting pins, not shown for clarity, disposed in the channel with the block and plate under the draw force of the nut and bolt binding the pins in the channels in adjusted position.

The device is easily mounted on a how 11 by fixing the track thereon via the

screws

70 and 71, FIGS. 6 and 8, and the carriage 12 is then easily mountable on the bar 20 by sliding the

ways

31 and 3 2 through the recessed or reduced portion 33 of the legs 21 or 21-A whereupon the spring 35 is compressed under torsion frictionally engaging the block 29 on the slide bar 20 portion of the track. 7

In operation, the archer loosens the nut 57 permitting the apertures of the head 56 and the block 29 to align whereupon he selectively inserts the

pins

16 and 17 from either side of the block so as to position the sighting prism or cross hairs 18 on either side of the block and he then screws the ball sight pin 14 into the head 56 threaded apertures 14-A from the other side of the device opposite to the sight 18 whereupon the device is positioned as desired. He then moves the

pins

16 and 17 and the pin 14 inwardly and outwardly sidewardly of the bow until the desired location is obtained whereupon by tightening the nut 57 the

sight supporting pins

14, 16, and 17 are locked in the desired position. The archer then moves the carriage block 29 upwardly and downwardly on the slide bar until the proper sight is obtained or moves the index arm '13 relative to index marks of the bow to the desired elevational position whereupon the slide block is held under the torsion of the spring 35 and/or by tightening the set screws 42 as desired. In the event a plate 63 is employed it is to be noted that the plate has surrounding apertures not in engagement with the set screws 42, for insertion of a screw driver therethrough to render the set screws 42 tumable. Similar or the same

sight supporting pins

16 and 17 are also inserted in the channels between the plate 63 and the block top 50 as formed by the

grooves

61, 62, 64, and 65 it is obvious that by tightening the nut 57 that the plate 63 is jammed downwardly against the block locking the

pins

16 and 17 in the channels formed by the opposed grooves.

While the

pins

16 and 17 have been shown interconnected, it is obvious that they can be separately disposed and independently support different sighting devices and that the device can support several and/or multiple sets or individual pins at desired locations for the purpose of supporting visual sights suitable to the multiple and hard to satisfy demands of an expert archer.

Although but a few embodiments have been shown and described in detail, it is obvious that many changes may be made in the size, shape, detail, and arrangement of the various elements of the invention within the scope of the appended claims.
