Abstract
An adjustable compound leverage bowstring release which may be held in the hand of an archer includes a housing assembly, a latch cam which is pivotally mounted to the housing assembly and a trigger cam which is also pivotally mounted to the assembly. The housing assembly has an outer contour which is shaped to be grasped by the hand and also has a slot for receiving a bowstring. The latch cam has a notch which receives the bowstring when the bowstring is pulled into the housing assembly slot. As the bowstring is pulled back into the slot, the latch cam is pivoted from its open position to a latched position. In its latched position a lever portion of the latch cam moves through a lever pathway. The trigger cam then is pivoted so that a smooth wall on the trigger cam intersects the latch cam lever portion pathway to prevent the latch cam from returning to its open position. When the archer's hand releases the latch cam, the trigger cam is free to pivot out of the pathway of the latch cam lever portion, thereby allowing the latch cam to pivot to its open position where the bowstring is released.
