Abstract
A caliper type bow string release includes a reversible trigger which is operable selectively in either the push fire mode or the pull fire mode. The caliper jaws of the release include automatic alignment and locking features, whereby movement of the string into a retaining notch engages the automatic locking mechanism and closes the release into a string retaining position until the release is fired by activation of the trigger. A complex cam surface is provided on the actuator for permitting incremental linear adjustment of the trigger force. In one embodiment, each jaw includes an arcuate socket in alignment with a complementary socket on the opposing jaw. A spherical member is received in the sockets. A head is secured to the spherical member and extends into the retaining notch; placement of the string against the head pivots the jaws to the closed position. In another embodiment, each jaw includes an arcuate synchronizing tab to be received in a concave arcuate recess in the complementary jaw. An automatic latching feature comprises a latch tab and complementary latch receiving seat on each jaw. The latch tab is adapted to intercept the bow string as it is introduced into the retaining notch to pivot the jaws closed.
