A non-penetrating captive bolt device includes a threaded mechanism for retracting a bolt against a biasing force. The bolt includes an elongated rod that projects rearward from the rear end of the bolt through a compression type spring that biases the bolt forward. A trigger actuated catch is mounted on the threaded mechanism with an internal bore, and the rod extends therein. When the threaded mechanism is advanced forward, the trigger actuated catch is advanced forward and engages the elongated rod. Retracting the threaded mechanism retracts the elongated rod and compresses the spring. Actuating triggers on the trigger actuated catch releases the elongated rod and the spring biases the bolt to a forward position.

A pneumatic stunner for stunning an animal has a piston slideable within an inner chamber, and a stunning rod driven by the piston forward and rearward towards and away from the front end of the housing. The stunning rod has an elongated body having a longitudinal axis and a detachable hardened tip. The density of the material comprising the elongated body is less than the density of the material comprising the detachable hardened tip.

A pneumatic animal stunner for stunning an animal for later processing uses sensor technology to measure the speed of a stunning rod disposed in the stunner housing as it is driven forward via pneumatic forces. At least one sensor may be disposed in a nose connected to a front end of the housing, in the housing, or in a tail end of the housing. The at least one sensor communicates with a receiver that can process and display the speed data collected from the at least one sensor as the stunning rod drives forward. The receiver can be disposed on the housing of the stunner, or may be a separate component from the stunner. The data may be sent from the at least one sensor to the receiver via a wireless or wired connection. Multiple methods of measuring the stunning rod speed may be employed.

A portable pneumatic stunner for stunning or euthanizing an animal has a piston slideable within an inner chamber, a housing with a front portion being moveable toward and away from its rear portion, a stunning rod driven by the piston forward towards the front end of the housing, a catch system for alternately holding and releasing the stunning rod, and a regulator for regulating the pressure received from a fluid container for operating the stunner. The stunning rod is driven along a longitudinal axis upon exposure of a pressurized fluid to the piston, and the stunning rod is retracted back into the stunner after firing by exerting a manual inward force on the stunning rod and housing. The catch system comprises a plurality of arcuate sections substantially forming a cylinder. The regulator determines the allowable pressure levels of the fluid the stunner is subjected to.

An animal stunner for use in livestock/slaughterhouse operations has a piston slideable within an inner chamber, and a fire pressure chamber with an annular configuration disposed adjacent the rearward or central end of the inner chamber. A stunning rod is driven forward by the piston to stun the animal and rearward to retract the rod. A valve system alternately controls flow of the pressurized fluid from the fire pressure chamber to the rearward end of the inner chamber to move the piston and drive the stunning rod. A catch system holds and releases the stunning rod. A compressed fluid supply is used to retract the stunning rod between operation cycles. Handles employing triggers are used by the operator to hold the stunner and to activate the valve system, and cushion mount systems are attached between the handles and stunner housing to absorb shock while operating the stunner.
