ABSTRACT:
A bowstring release device for drawing and releasing a bowstring to propel an arrow to the target. The structure comprises a body, a wheel-like holding member and a wheel-like locking member. The holding member has a concave radius cut into its periphery that matches the periphery of the locking means. The locking means also has a radius cut into it's periphery that matches the periphery of the holding member. The two parts are very closely fitted on pivot pins so that the two parts are always in contact with each other. When the device is in a cocked position, the holding member is locked by the periphery of the locking member which extends into the radius cut into the periphery of the holding member. As the locking member is rotated to it's second position the forward edge of the radius cut into the periphery of the locking member emerges from the radius cut into the periphery of the holding member releasing the holding member and allowing the periphery of the holding member to enter the radius cut in the periphery of the locking member as the holding member rotates to release a bowstring.
