ARcHERs ARRow Nocx AND FINGER GRIP Filed March 2a, 195s ROBERTA. CHELLG 7' OPP /m/TRNEYS United States Patent ARCHERS ARROW NGCK AND FINGER GRIP Robert A. Chellstorp, Bloomleld, Conn. Application March 28, 1958, Serial No. 724,606

4 claims. (cl. 124-35) i This invention relates to improvements in gripping and triggering devices adapted to be for use by archers.

A major object of the invention is to provide an improved andsimplied archers hand grip and trigger device which reduces the skill heretofore required for proper gripping ofthe bow string with a conventional arrow in nocked engagement therewith, while simplifying manual release of the arrow from a desired anchor point, such as from a chin anchor or a cheek anchor, substantially to improve the marksmanship of the average archer.

A further object is to provide an improved archers hand grip and trigger device which permits archers of limited skill to use the same arm and hand movements employed by highly-skilled archers without use of the grip, and to do so in the absence of the substantial skill heretofore required for perfect linger release of the bow string, thus reducing the time heretofore required to obtain archery proficiency. v Other objects will be in part obvious, and in part 'pointed out more in detail hereinafter.

f The invention accordingly consists in the features of onstruction, combination of elements and arrangement .Joffparts which will be exemplified in the construction hereafter set forth and the scope of the application of which will be indicated in the appended claims.

`In the drawings: v

lFig. l is a side elevation, partially in phantom of a hand grip mechanism incorporating the invention.

Fig 2 shows in elevation a hand grip mechanism havgan alternate embodiment of the invention incorporated therein.

Fig. 3 is a vertical section of the-shank portion of the device of Fig. 2.

Fig. 4 is a top plan view of the device of Fig. 1.

Fig. 5 is a section taken along lines 5--5 of Fig. 1 with the jaws of the device closed.

Fig. 6 is a view similar to Fig. 5 but with the jaws open.

Figs. 1, 4, 5 and 6 show an 'archers triggerable hand j grip device incorporating a preferred embodiment of the invention and comprising a shank-like finger grp'10 and forwardly extending set of ljaws generically designated 11. Jaws 11 include a jaw arm 12 having one end fixed to shank 10 as by welding, the drawings showing that arm as an intergral extension of the shank material for convenience of illustration. A second jaw arm 13 is mounted to pivot in respect to arm 12, as later described, both arms 12 and 13 being of identical configuration forwardly of the pivot point of arm 13 to terminate in enlarged jaws 16 and 17, contoured to define, when closed, an ontwardly open cylindrical arrow nock receiving socket 18 positioned longitudinally of the arms and a vertical string bore 19 `disposed to intersect socket 18. Jaws 11, when open, receive arrow 61 with bowstring 60 nocked thereto, and when closed, lock the arrow and string therein.

Shank 10 preferably is diagonally positioned in respect to arms 12, 13 to facilitate ease of hand positioning at spaced plates 23, 24 which are mounted to the top and bottom surfaces, respectively, of arm 12' by rivets 25 and extend laterally of arm 12 a sufficient distance to anchor pintle 22 as shown. Shank 10 is provided with a centerbore 28 extending downwardly to terminate in a closed end 29, the upper end thereof leading into a diametric channel 34 between shoulders 30 and 31, extending downwardly to shoulders 33 and 41. A closure member 36 of right angular shape is disposed in channel 34 and riveted to shank 10 at 37 with one'leg 35 thereof closing the upper channel end and the other leg 40 closingthe side above arm 12, leaving the opposite side of the-channel open fromthe lower face of leg 35 to the bottom shoulder 33 thereof.

Referring to Figs. 5 and 6, the inner end portion 17 of leg 13 is tapered, starting near pintle 22, to reduce the leg to approximately half its width at the inner Vend thereof, thus permitting pivoting of the outer end of leg 13 to the jaw open position of Fig. 6 which positions the inner tapered end thereof in abutment with the inner surface of arm 12 as shown with tongue 14 extending into the shank bore. To provide clearance for such pivoting, shank 10 is provided with a forwardly opening notch 43 is disposed within centerbore 28, the upper end thereof carrying a thumb depressible lever 53 projecting throughslot 34 for movement of plunger 45 downwardly against the bias of a coil spring 46 in bore 28, the limits of movement of plunger 45 being set by stops 33 and 35 respectively. Plunger 45 is provided with a forward lateral notch 49 shown dotted and above shank notch 43, Fig. l, but registerable, with the plunger depressed, with shank notch 43 to permit tongue 14 of arm 13 to be swung into bore 28 to be detent held therein, upon plunger release. Upon manual closure of jaws 11, tongue 14 swings out of bore 28 and plunger 45 snapsuupwardly to prevent tongue 14 from moving inwardly, thus locking the jaws until released by subsequent depression of plunger 45. With a drawn bowstring held in the string bore, the jaws instantly fly apart upon depression of plunger 45 by lever 53 with attendant release of the arrow.

In the device of Figs. 2 and 3, shank 110 is shown disposed in right angularity to the jaw members 111 rather than being diagonally disposed in respect thereto. The device functions in a similar manner, however, with plunger provided with a forward notch 65 for registry, when depressed against spring 146 by thumb engageable extension 70 with shank groove 143 to permit tongue 114 of pivoted arm 113 to enter notch 65, thus opening the jaws, tongue 114 being detent held by plunger 145 under urge of spring 146. When the jaws are closed, plunger 145 snaps upwardly to lock them in the manner above described. Plunger 145 is provided with an axially extending notch 66 into which the inner end of a stop member 67 projects to limit the vertical movement of plunger 145.

' I claim:

1. In a device of the character described, a first jaw having a center-boredv handle secured thereto in a plane transverse to the axis of said jaw and having handle portions disposed above and below said first jaw, a second jaw pivotally attached to said first jaw for movement yabout an axis generally co-planar with said handle and Patented May 17, 196)` biasing spring, to provide clearance permitting said tongue portion to be swung into the centerbore.

2. -In a device of the character described, a shank, a pair of arrow nock and bowstring recreiving'jaws extending laterally from said shank intermediate the ends thereof, one jaw being fixed thereto and the other jaw pivotally attached to the xed jaw for movement about an axis generally co-planar withl said shank, said shank being longitudinally chambered and radially notched adjacent the base of the jaw fixed thereto, said pivoted jaw including a tongue positioned to be pivoted into said shank notch, a plunger in said chamber provided With a notch to allow pivoting of said tongue into said chamber when aligned with the shank notch and to prevent such pivoting when non-aligned therewith, a depressible lever extending outwardly of said shank for the control of said plunger, and a spring biasing said plunger in a position of non-alignment of said notches.

3. In a device of the character described, a rst jaw having a handle securedthereto in ay plane transverse to the axis of said jaw, said handle having portions thereof extending above and below the axis of said first jaw, a second jaw-pivotally attached to said first jaw for movement about an axis generally co-planar with said handle and having a tongue portion positioned to be pivoted into the handle when the second jaw is moved into an open position, and a channeled plunger s'lidably disposed Within the handle with a thumb operable portion projecting therefrom, means biasing said plunger in a direction of non-alignment of its channel with the tongue portion of the second jaw to lock the pivoted jaw in a closed position, but movable, by thumb depression, against the biasing means into alignment to unlock the pivoted jaw and permit pivoting thereof to an open position.`
