Abstract
The bowstring drawback and release device of the invention has a handle member that is advantageously of comfortably contoured T-formation in which the stem of the T extends forwardly and is connected by ball and socket joinder to a support for a bowstring catch. The support is in the form of a housing that is desirably open at its forward end and along its bottom, the catch being a lever within and pivoted to the housing intermediate its ends so as to drop open upon release effected by pulling a resiliently biased trigger that is pivoted within the housing and extends outside for convenient pulling, as by the thumb of the hand of an archer holding the handle. An important feature is the provision of a transversely segmented, longitudinal, composite rod having a laterally confined, rigid, forward end segment that is adapted to engage a rearwardly shouldered portion of the catch for holding the bowstring in engaged drawback position and a laterally unconfined, rearward end segment of stiffly flexible material connected to the trigger for accommodating any misalignment of the handle member when the trigger is pulled.
