Abstract
An animal trap is powered by compressed gas and includes a trigger mechanism and kill mechanism. The trap is preferably self-resetting. A variety of sources of compressed gas may be used, and different kill mechanisms may also be used. The trap is particularly suited to applications where low-maintenance traps are required, because it uses a simple, reliable mechanism which can kill a number of animals over a long period of time without requiring maintenance or manual resetting.
Claims29
A trap including:
- i. a source of compressed gas;
- ii. a trigger mechanism configured to be actuated by an animal;
- iii. a kill mechanism powered by compressed gas;
- and
- iv. a diaphragm that in a ready state blocks flow of compressed gas to the kill mechanism;
- wherein, when the trigger mechanism is actuated by an animal, the diaphragm moves so as to allow gas to flow to actuate the kill mechanism to kill the animal.

A trap as claimed in claim 20 wherein in a setting, resetting or ready state the diaphragm blocks the end of the central cylinder, and the movement of the diaphragm when an animal actuates the trigger is away from the end of the central cylinder such that gas flows from the intermediate reservoir into the central cylinder to act on the piston.

-34. (canceled)
A trap including:
- i. a source of compressed gas;
- ii. a trigger mechanism configured to be actuated by an animal;
- iii. a kill mechanism including a piston powered by compressed gas and a hammer, spike, striking element or cutting element formed integrally with the piston or carried on an end of the piston;
- wherein, when the trigger mechanism is actuated by an animal, gas flows to actuate the piston of the kill mechanism, which is arranged to move the hammer, spike, striking element or cutting element to strike or cut the animal, thereby killing the animal.
A trap including:
- i. a source of compressed gas;
- ii. a trigger mechanism configured to be actuated by an animal;
- iii. a kill mechanism including a piston powered by compressed gas;
- wherein, when the trigger mechanism is actuated by an animal, gas flows to actuate the piston of the kill mechanism to kill the animal, the trap further including a flow path allowing gas to flow from behind the piston after actuation, thereby relieving the pressure acting on the piston to allow resetting of the piston under a restoring force.
