ADJUSTABLE ARCHERY SIGHT BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a finger-operative sighting device for mounting on an archery bow and particularly, to an improved device for accurately sighting an arrow during movement of a target.

2. Description of the Prior Art The archer-hunter has always encountered the problem of properly sighting an arrow in attempting to shoot a moving target, such as deer or other wild game. In this connection, ordinary sights, such as used for target shooting, have not been practical in that if the game is moving, it is difiicult, if not impossible, to keep the sight set properly to keep the arrow accurately aligned with the game for release at the appropriate time. Some archers use a stationary sight and then pick out a certain pin or mark to correspond with the yardage that is to be shot. An adjustable sight has been illustrated in my US. Pat. No. 3,450,122 which uses electric signaling means to automatically indicate when the tip of the arrow has reached a proper shooting position. It will be noted that utilization of a slide such as disclosed in this patent requires either the more or less free use of the right or left hand and thus, a release of the arrow from its shooting position. In accordance with the present invention, however, both hands may be in customarily required positions at which an arrow is ready for shooting.

SUMMARY OF THE INVENTION In order to meet the above problem, I have devised a finger actuated device which is constructed and positioned forwardly of the bow, adjacent a natural, gripping position of the left hand (assuming'the use of the equipment by a right-handed person). The construction enables the index or first finger of the left or bow-gripping hand to be used to continually or to,

as desired, effect a movement of a vertically slidable sight-carrying element to quickly adjust the sight position to accommodate it to an instant position of the target at a particular moment. This is done without any need for the archer to release his left hand from a tight gripping position about the bow or his right hand from a fully backward drawn ready" position of the arrow. The construction is such that no noise is involved that may spook the game. The construction of the mechanism enables the archer to assume his natural shooting position or customary hand gripping relationships and to adjust the sight without adversely changing proper shooting gripping positions of principal digits of the hands.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view in elevation showing a bow string as drawn back by an arrow to a typical shooting position.

FIG. 2 is an enlarged side fragment in elevation through a central body portion of a bow incorporating the mechanism of the invention; it will noted that this view is taken along a wide side or face of the bow.

FIG. 3 is a fragmental narrow face view in elevation on the scale of FIG. 2, further illustrating the construction and positioning of mechanism of the invention.

FIG. 4 is an elevational fragment on the scale of FIGS. 2 and 3, taken from the back of the bow and further illustrating the mechanism of FIG. 3. v

FIG. 5 is an elevation on a further enlarged scale showing details of the construction of a sighting means that may be utilized in accordance with the invention; as shown in FIG. 3, the sight is mounted on the belly of the bow above a forwardly necked hand-gripping portion of the bow.

FIG. 6 is a side view in elevation on the scale of and taken at right angles to FIG. 5, along line VIVI thereof.

FIG. 7 is a top plan view on the scale of and of the sighting means of FIG. 5.

FIG. 8 is a front view in elevation of an operational control part or unit of the mechanism of the invention; this part, as illustrated particularly in FIGS. 1 and 2, is adapted to be mounted on the back of a bow adjacent to and above a handgrip portion.

FIG. 9 is a side view in elevation on the scale of and of the part or unit of FIG. 8; FIG. 10 is a top plan view thereof on the same scaleas FIGS. 8 and 9.

And, FIG. 11 is a fragmental side view in elevation on the scale of FIG. 2, illustrating a modified utilization of the mechanism wherein control strands or threads are carried along the outside of the bow rather than as shown in FIGS. 2 and 9, through a bore hole extending from its front to its back face.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1 of the drawings, an archery set consisting of an arrow A, a flexible bow B and a bow string C are illustrated in a so-called drawn or ready shooting position. In this position, assuming a right-handed person, the left hand of the archer will be gripped around a forwardly necked-in central portion 18 of the bow B, with the thumb extending across a narrow face b and along far wide side face c, andthe fingers extending along near wide side face a, about and across face d to meet the thumb along the side face c. It has been determined that the remaining three fingers and the thumb of the gripping hand will provide a full gripping retention of the bow B in its expanded relation, if the index or first finger is released to fit within spokes of a control, operating device or part E of the invention. As shown particularly in FIGS. 2, 9 and 11, control device or part E is adapted to move a sighting device or part D vertically along the narrow face b of the bow B. At this time, of course, the right arm will be drawn back and the right hand will be gripping the nocked end of the arrow A adjacent the apex of the draw string C. It is thus believed to be apparent that the archer or hunter may-retain his equipment in the fully drawn ready" position of FIG. I and, at the same time, quickly and easily adjust the sighting device D to the actual momentary position of the game or target.

For the purpose of illustrating the invention, a somewhat typical sighting device D has been illustrated. It has a vertically extending slide-receiving rod or guide bar of rectangular section 10 mounted at its ends on top and

bottom positioning brackets

12 and 16. The top bracket l 2,'as shown in FIG. 2, is of angular shape and is secured, as by a nut and bolt assembly 13, to a second, dog-leg type of direct mounting bracket 14 (see FIG. 2). As shown in FIGS. 2 and 6, the assembly 13 extends through a hole 120 in the bracket 12 and a similar hole in the bracket 14. The bracket 14 is shaped to be securely mounted on the narrow face of belly of the bow B by suitable means such as wood screws 15. The bottom bracket 16 at the other end of the slide or guide bar 10 is also of angular shape and is directly mounted on the belly by wood screws 17 (see also FIG. 6). This provides a rigid mounting for the sighting part or device D at which the slide bar 10 is retained in a substantially fully vertical position.

Slider block or element 20 has a rectangular bore therethrough for mounting it on the bar 10 in an easily slidable, but frictional, position-retaining relation with respect thereto. The slider 20, carries an upper eyelet lug or tab 20a that is adapted to be connected to one end of a control or operating filament, thin wire, thread, strand or string 37, and has a bottom eyelet or tab 20b that is adapted to be connected to a second control or operating filament, thin wire, thread,

actuated by the sighting control device E. The slide 20, as shown particularly in FIGS. 3 and 5, may have any suitable type of sighting device, such as a peep sight 23, carried thereby. The unit or device D also has a side-positioned calibrated scale 11, and the slider 20 has a through-extending alignment pin 21 that is adapted to align with the graduations on a vertical scale 11, see particularly FIGS. 5 and 7. The sight 23 is shown carried on a threaded stem 23a in order that it may be adjusted transversely, horizontally as to its positioning on the slider 20. Set screw 22 is employed to lock it in a desired setting.

The sighting control device E, as shown particularly in FIGS. 2, 3, 4 and 8 to 11, has a base mounting plate part or member 30 that is adapted to rest upon and to be secured to the back of the bow. In the embodiment shown in FIGS. 3, 4 and 8, the base plate member 30 has a pair of

holes

30a and 30b therethrough for receiving mounting wood screws 32 (see FIG. 4) and a central hole opening or eyelet 30c therethrough for bypassing the

operating filaments

37 and 38. A pair of fingers define a backwardly downwardly outwardly inclined, bifurcated, supporting bracket 31 that extends integrally from the base plate member 30 and, at its outer end, rotatably or pivotally carries a pin shaft 34 which extends therethrough and on which a two-part, index finger operated pulley 35 is securely mounted for rotation therewith.

As shown in FIG. 10, the pulley 35 has a pair of adjacent compartments 35a and 35b to respectively receive ends of the two

operating filaments

37 and 38 which may be secured within the respective compartments by set screws 36.

One of the filaments 37 may operate from or over the top of its pulley compartment 35a, while the other filament 38 may operate from the underside of its compartment 35b (see the dot and dash lines). As shown, the upper filament 37 extends backwardly along with the lower filament 38, either through a bore hole 19a in stock part 19 of the bow B (see FIGS. 2 and 9) or through an eyelet 39 (see FIG. 11) and along near side a of the bow; the filaments are connected at their other ends by closed loops respectively to the upper and lower eyelet lugs 20a and 20b of the slider 20. The filament 37 is looped through

adjacent holes

12a and 12b in the bracket 12 and is connected at its inner end to the lug 20a. Thus, if the spool 35 is rotated counterclockwise (see the arrow e of FIG. 9), this will cause the upper filament 37 to wrap around the spool 35 and pull the slider 20 upwardly and will cause the lower filament 38 to run-off or play-out from the spool 35 by the same amount. If the rotation is reversed to a clockwise rotation as indicated by the arrow f, then the bottom filament 38 will tend to pull the slider 20 downwardly and wrap it on the spool 35, while the upper filament 37 will run-off the spool 35 or playout by the same amount.

It will be noted (see FIG. 6) that both

filaments

37 and 38 extend through a horizontal eyelet or opening 16a, that filament 37 extends through adjacent vertical eyelet or opening 16b, and that filament 38 extends through vertical eyelet or opening 160 in the bottom bracket 16. The upper filament 37 is looped or reversed through a pair of adjacent vertical eyelets or

openings

12a and 12b in the upper mounting bracket 12, see particularly FIGS. 2 and 6. The

filaments

37 and 38 thus extend in an interleaving relation through eyelets or openings. For easy and efiective operating of the pulley 33 and thus raising and lowering of the sight 23 through the agency of the slider 20, a finger receiving and operated, notched or sprocket-like finger-operated wheel 40 is securely mounted on the shaft 34 to rotate it. The wheel 40 is shown provided with a group of four radial spokes 41 that extend radially and axially outwardly (see FIGS. 8 and 11) and that are adapted to receive and bypass the index finger of the left hand of the archer in such a manner that the pulley 40 can be turned or rotated by the index finger to move the sight up and down. It is only necessary to flex or unflex the index finger of the hand in engagement with one or a pair of the outwardly extending spokes 41. It will be noted that four spokes 41 are shown in an equally spaced arrangement and have their outer radial ends tumed-outwardly in the direction of the axis of the shaft 34. In FIGS. 2, 3 and 4, a bristle type of arrow rest 45 is shown replaceably positioned in a side opening to project slightly outwardly from the stock portion to present an arrow guide.
