Abstract: A tool driver which has a body having a bore. The bore has a longitudinal axis. A plunger is disposed in the bore. The body and the plunger have a lock. An actuator is disposed on the body. The actuator and the plunger are loosely coupled. The actuator is axially movable relative to the body and the plunger between a locked position and a retracted position. The actuator, in the locked position, substantially immobilizes the plunger relative to the body. The actuator and the plunger are axially movable together, relative to the body, between the retracted position and an extended position.

Abstract: A device for a human to produce animal calls comprises: a main body with first and second ends and an intermediate portion therebetween and a longitudinal air passage therethrough from the first to the second end; a reed with a restrained end and an unrestrained end, positioned atop a portion of the air passage so that the user's breath being expelled through the air passage causes the unrestrained end to vibrate; a plate for retaining the restrained end of the reed against the main body along the intermediate portion thereof; and a generally elliptical solid piece of resilient foamed polymeric material for gripping the device between the teeth and/or lips of the human user. The device may further comprise an "O" ring frictionally engaged around the reed and the main body and compressing the reed against the main body along the respective intermediate portions of the reed and the main body.
