ABSTRACT:
A rodent exterminating apparatus having a frame on which a pivotally mounted striking bar is operable to be moved from a retracted position to a striking position by a pneumatic actuator including a one way spring return rolling diaphragm operated plunger. The actuator is operated by a pneumatic control circuit which senses the presence of a rodent to cause a fast acting valve to direct pressure air to the actuator from a reservoir chamber which is formed as part of the actuator. The control circuit includes a pneumatic time delay device which automatically moves the control valve to reset the striking bar after a predetermined period of time commencing with deactivation of a trigger or proximity sensor in the control circuit.
