A conventional arrowior use'with the bow is indicated by the numeral 12. The arrow 12 is provided at the rear end thereof with a nock 13 which is slotted in the usual manner for engagement with the bowstring 11- A preferred embodiment" of the present invention, is shown in Fig. 1 and in a position wherein itis opera-' tively engaged with the string 11- and arrow 12 preparatory to the releasing of the same.

the hole 40 and engages the lower enlarged end 42 of the t igger 39 and functions to normally bias the trigger upwardly to the position shown in Fig. 2 whereby the release pin 35 is held in' a releasably locking engagement in the hole 34. The trigger portions 38 and 42 are connected by the reduced portion 43. The vertical movement of the release trigger 39 is limited by means of the nose 44 on the screw 45 which is threadably mounted in the hole 46 formed on the rear side of the grip member 14. The screw nose 44 extends into the hole 40 opposite the reduced trigger portion 43 and the spring 41 urges the enlarged trigger portion'42 normally upwardly into engagement with the screw nose 44. The trigger 39 further includes the upper reduced portion 47 which extends upwardly from the enlarged portion 38 which terminates in the enlarged head portion 48. The upper end of the hole 40 is enlarged to receive the enlarged trigger head portion 48. I

The device of the present invention includes the two arrow and string engaging fingers generally indicated by the numerals 49 and 50, and these fingers are rotatably mounted on one side of the device, as shown in the drawings. The illustrative device is made to be used by a right handed archer and, accordingly, the fingers 49 and 50 are mounted on the left side of the arm 18. It will be understood that a device embodying the principles of the invention could be similarly made for use by a left handed archer, if desired. As shown in Fig. 2, the arm 18 is provided with an inwardly extended concave recess 51 which is centrally longitudinally disposed. Equidistantly disposed on either side of the recess 51 are the fingers 49 and 50 by means of the screws 52 and 53, respectively. The screws 52 and 53 are rotatably mounted in the bushings 54 and 55 which are fixedly mounted in the holes 56 and 58, respectively, in the fingers 49 and 50, respectively. The screws 52 and 53 are threadably mounted in the horizontal holes 59 and 60, respectively. As shown in the drawings, the fingers 49 and 50 are vertically disposed apart and are arcuately formed along the inner side faces thereof, and these inner faces are further provided with the string grooves 61 and 62, respectively. The fingers 49 and 50 are normally biased into the free position shown in Fig. 2 by means of the springs 63 and 64 which are mounted in the grooves 65 and 66 which are formed along the inner faces of the fingers. It will be seen that the outer ends of the springs 63 and 64 engage the pins 67 and 68 which extend outwardly from the arm 18 and into the inner ends of the spring recesses 65 and 66. The outer ends of the springs 63 and 64 engage the outer end of their respective recesses.

The lower side of the upper finger 49 is provided with a straight edge 69 which slopes inwardly and upwardly when the finger is biasedto the unloaded position shown in-Fig. 2. The outer end of the straight edge 69 is rounded as shown by the numeral 70. The lower finger 50 is provided with a similar straight edge 71 on the upper end thereof which slopes inwardly and downwardly and which terminates in the rounded corner 72. As shown in Figs. 2 and 3, the upper finger 49 is provided with the slot 73 in the lower end thereof which extends inwardly from the outer face to provide a lower flexible gripping portion 75 along the inner edge thereof. The lower finger 50 is provided with a similar slot 74 to provide a similar flexible nose portion 76.

the slots 73 and 74 formed in the fingers 49 and 50,

the nose portions 75 and 76 on the fingers function to provide an efiicient grip on the arrow nock yet they are.

flexible so as to permit an easy and quick release of the arrow. When the user has pulled the arrow 12 back to the desired position, he merely presses downwardly on the trigger head 48 with his thumb to release the arrow. When the trigger'39 is pressed downwardly the pressure on the fingers 49 and 50 of the drawn string 11 will pivot the arm 18 and force the release pin 35 rearwardly into the hole 40 opposite the reduced trigger portion 47. The arm 18 will be pivoted clockwise, when viewed as in Fig. 5, and the spring 11 will roll sidewardly out of the grooves 61 and 62 in the fingers thereby sending the arrow on its way. It will be seen that the device of the present invention permits the user to pull back the arrow string with the full strength of is four fingers whereby the thumb is still free to operate the trigger 39. After the arrow has been released the recoil of the bow string 11 kicks the arm 18 back to the cocked position whereby the device is ready for instant reloading.

While it will be apparent that the preferred embodiment of the invention herein disclosed is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope or fair meaning of the subjoined claims.

What we claim is:

1. A device of the character described, comprising: a

grip member having an upper arm and a lower arm extending horizontally outwardly therefrom; a vertically disposed arm pivotally mounted between said upper and lower arms; a pair of spaced apart bow string engaging fingers on one side of said vertical arm in the same vertical plane; said fingers being separately rockably mounted on the vertical arm and being operable to frictionally grip an arrow therebetween when the fingers are engaged by the bow string to draw it taut and cam the fingers against the arrow; and, a trigger operated release fingers are provided with a groove along the inner side thereof for the reception of the bow string; and, the fingers are each provided with a flexible pressure relievring portion on adjacent sides thereof to prevent excess pressure on the arrow nook and any resultant damage .In use, the device of the present invention is carried thereto.

3. The device as described in claim 1, wherein: said trigger operated release means includes a release pin releasably engageable with said vertical arm, and, a manually operable spring biased trigger adapted to normally retain said release pin in engagement with said vertical arm. I
