ABSTRACT:
Described is a pneumatic animal stunner that includes a physical catch for the piston that drives the stunning element. This allows pressure to build up behind the stunning element immediately prior to firing rather than requiring the introduction of pressurized air or fluid at the time of actuation, as is common in the prior art. The result is a faster, more effective stroke. The animal stunner also includes a dual trigger mechanism for safety. The animal stunner has a conventional trigger that is activated to pressurize the stunner and an activation means located in its front end. The activation means releases a physical catch that retains the piston in place. Preferably, the activation means is operated when depressed against the animal. The animal stunner is designed so that the stunning element may not be fired more than once for each time the trigger is pulled. In addition, the animal stunner includes exhaust vents that are directed toward the front of the device. By exhausting pressurized fluid toward the front of the device, excessive build up of animal tissues and other debris in the mechanism is prevented, reducing the need for maintenance.
