mmaiwmomdfl Patented May 5, 1953 ARROW RELEASING DEVICE Harry J. Rose, West Allis, Wis., assignor to Make- All Tool & Die 00., West Allis, Wis., a corporation of Wisconsin Application August 3, 1950, Serial No. 177,520

3 Claims.

This invention relates to improvements in arrow releasing devices. In archery, the arrow nock is engaged with the string of the bow and, under conventional practices, it is so held by the fingers of the archer while the string is pulled, the arrow nook and string being ultimately manually released, causing the shooting of the arrow in the desired direction. The above conventional practice in respect to shooting an arrow from a bow makes the accuracy of the shot dependent upon the operation of the archers fingers in releasing the arrow nock from the taut string of the bow. Even with an expert archer there is lack of uniformity in respect to repeated manual releases of arrows. The conventional practice furthermore is hard on the fingers, hand and arm of the archer and some archers find it necessary to wear finger gloves and arm guards.

With the above in mind it is, therefore, a primary object of the present invention to provide an arrow releasing device which, through operative mechanical means, en ages the arrow hook with the taut retracted string of a bow and permits the uniform and smooth release of the arpurpose insuring a uniform and smooth release of arrows from the bow upon each shot.

A further object of the invention is to provide a mechanical trig er operated arrow releasing device which secures an arrow to a bow string in a manner so that the frictional restraint on the engaged arrow is always uniform.

A further obiect of the invention is to provide an arrow releas n device in the nature of a trigger operated pistol grip which. for shooting purnoses. is'easy to operate and eliminates the need for the wearing of gloves or arm guards by the archer.

A further object of the invention is to provide a mechani al arrow releasing device which will accommodate arrow nooks within the conventional size deviations and in which a friction spring bearing on the engaged arrow nook is adjustable to adapt it to arrow nooks of varying diameters.

A further object of the invention is to provide an arrow releasing device which is of very simple construction, is simple and accurate in its operation, which may be used with all standard archery bows and arrows, and Which is well adapted for the purposes described.

With the above and other objects in view, the invention consists of the improved arrow releasing device and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is a fra mentary side view of a bow having the string thereof taut or retracted and releasably en aging the nock of an arrow by means of the improved arrow releasing device;

Fig. 2 is an enlarged fragmentary view of one side of the arrow releasing device with a plate removed to show the internal mechanism, the plate retaining screws being in section;

Fig. 3 is an enlarged front view of the portion of the arrow releasing device shown in Fig. 2, releasably engaging an arrow nook and bow string, the arrow nook being shown in section;

Fig. 4 is an enlarged fragmentary view of the arrow releasing device showing the side portion thereof opposite that shown in Fig. 2; and

Fig. 5 is a fragmentary detail sectional view taken on line 5-5 of Fig. 3.

A conventional archery bow is indicated by the numeral 3 and it includes a string 9 secured at its ends to the ends of the bow (not shown) and adapted to be drawn rearwardly to a taut position for arrow shooting purposes. A conventional arrow for use with the bow is indicated by the numeral Hi. The rear end portion of the arrow carries a nock H which is slotted as at 12 for enagement with the bow string 9.

' The present invention is concerned with a mechanically operated arrow releasing device, indicated generally by the numeral I3 and shaped generally like a pistol grip having a solid handle or grip portion l4 shouldered on its inner surface as at l5 to receive the forefinger of the archers hand which, during the operation of the device, is clasped about the grip portion M. The forward end portion of the arrow releasing device I3 extends horizontally and terminates in a downward extension It. The front face of the latter portion is formed with a vertically extending string receiving groove H which i intersected by a nook receiving socket l8 of a suitable size. Adjacent one side margin of the nook socket I8 is a forwardly projecting grooved guide block l9. A curved band spring 20 (see Figs. 2 and 3) has its inner end portion anchored to the stock of the portion IS of the releasing device within the socket and on the side thereof opposite the guide block I9. Said band spring 20 projects forwardly and its tension or arrow nock engaging infiuence may be regulated by a screw 2| whose inner end is adapted to bear against the spring and which is threaded through a curved locking plate 22 hingedly mounted on a pintle 23 carried by a hinge plate 24 secured to one side face of the downturned extension [6 of the releasing device l3. The locking plate 22 also ha associated therewith, at a substantial angle to the plane of the plate 22, a pair of spaced latching fingers 25 which, when the device is in its set condition, straddle the band spring 20 and extend transversely across the front edge of the portion 16, above and below the socket IS, in the manner best shown in Fig. 3, being releasably retained in this position by shouldered latch dogs 26. In a the latter operative, secured position of the fingers 25, the curved locking plate 22 assumes the position of Figs. 2, 3 and 5, with the screw 2| impinging against the free end of the band spring 20, placing the same under tension to cause it to frictionally bear against the adjacent side of the arrow nook ll, which is seated within the socket I8, as in Figs. 3 and 5.

One side face of the forward end of the grip shaped member I3 is recessed to niovably house the trigger and latch mechanism, as shown in Fig. 2, wherein the plate 2?, which closes the recesses and confines the mechanism, is shown as being removed. As will appear from Fig. 2 the forwardly projecting latch dogs 25 are in fact integral with the body portion of a vertically reciprocating plate 28 having enlarged slots 29 therein to receive fixed guide pins 30. The dog plate 28 is adapted to be reciprocated upwardly against the tension of a confined coiled spring 3| bearing against a flanged upper end portion of the plate 28. Pivotally mounted within an enlarged elongated recess therefor in the upper portion of the member I2 is a trigger lever 32 having its rear end projecting out of the handle extension above the grip portion M and provided with a thumb plate 3-3. The inner end portion of the trigger lever 32 is angled and extends under a shoulder 34 at the upper end of the dog plate 28. Hence, when the thumb plate 33 of the trigger lever 32 is pressed downwardly, the inner end portion of the trigger lever 32 will kick or reciprocate the dog plate 28 upwardly, against the tension of the spring 3|, raising the shouldered outer ends of the dogs 26 from their engaging relation with the cooked latch fingers 25, whereby said released latch fingers, under the influence of the band spring 22 bearing against the curved plate 22, will hingedly move said plate and fingers from the position shown in the drawing to a position at right angles thereto. When thumb pressure is removed from the thumb plate 33 of the trigger lever 32, the spring 3! will lower the dog plate 28 to its normal position.

The operation and utility of the improved arrow releasing device should be apparent from the preceding descriptive matter. However, to summarize, the nook ll of the arrow if! has its slot engaged with the bow string 9 in the usual manner. The nock is, however, mechanically releasably secured to the bow string by means of the device l3 which, prior to being engaged and set, has the latching fingers 25 released so as not to obstruct the string recess I! and the nock socket l8. The arrow nock is thereupon inserted into the socket E8 of the device with the adjacent portion of the engaged boW string 9 being accommodated by the groove or recess [1. The curved locking plate 22 is next pressed so as to carry the latching fingers 25 transversely across the front of the device 13 and the same snap under the shoulders of the latching dogs 26, whereby the device it becomes attached to the arrow nook and bow string and is in its set condition. One side of the arrow nock will seat within the recess of the guide block l9, which because of its length provides ample bearing surface. The other side of the arrow nock is firmly engaged by the band spring 20 which is then under tension. Through the means described, the frictional restraint on the engaged portion of the arrow nock is always uniform and there is a consequent uniform release of the arrow when the trigger lever is operatedfor arrow releasing purposes.

Although a plurality of rrows it are intended to. have nooks of uniform diameter, in practice there may be slight deviations ranging from A to g; of an inch. The socket I8 is sufficiently large to receive arrow nooks within these size ranges and the band spring 20, engaging one side of the arrow nock, insures a frictional engagement with an arrow nock regardless of possible size deviation. Furthermore, as previously stated, the adjusting screw 2| may be utilized for varying the tension of the band spring 20,

With the device engaged with the arrow nock i l and bow string 9, as previously mentioned, the archer then grasps with one hand the grip portion [A of the device l3 and pulls the bow string 9 and engaged arrow l0 rearwardly until the string is sufficiently taut or retracted for shooting purposes. Then, after taking aim, the archer at the desired moment presses downwardly on the thumb plate 33 with his thumb, thereby raising the dog plate 28 and disengaging the latching fingers 25 which, under the influence of the spring 20, then snap forwardly to a position at right angles to that of Fig. 3.

The engaged bow string is released and the frictional restraint on the arrow nook is overcome with the result that the arrow is shot from the released bow string in a smooth accurate manner.

From the foregoing description it will be evident that the improved arrow releasing device is of very simple construction, is easy, accurate and smooth in its operation, and .is well adapted for the purposes described.

What is claimed as the invention is:

1. A device for securing an arrow to a bow string and releasing the arrow for shooting purposes, comprising a grip member formed at its forward end with a nook socket adapted to be entered by an arrow nock and engaging bow string, a locking plate pivotally carried by the grip member laterally of said nock socket and including bow string engaging fingers, a spring having an end portion carried by said grip member and extending between said locking plate and an arrow nook within said socket and exerting pressure against the plate and nook, and a trigger operated mechanism associated with the grip member and releasably engageable with said fingers to hold the same in bow string confining position, manual release of the trigger operated mechanism reducing the spring tension on the arrow nook and permitting said spring to urge the locking plate and fingers to an inoperative position.
