Abstract: An animal trap utilizes a generally X-shaped base to provide a balanced mounting of a pair of U-shaped jaws, a pair of torsion coil springs, and elements of a trigger mechanism. When the trap is set, the jaws are pivoted downwardly relative to the base and lie in a horizontal planesurrounding a trigger pan, whereby the set trap is of minimal height. A means of adjustment is provided to enable the force required to operate the trigger pan to be adjusted through a wide range to accommodate the trap for use with a wide variety of animals. Mounting rods extend through two spaced coiled portions of each of the torsion coil springs to couple the springs securely to the base. The springs have U-shaped leg portions which engage sides of the jaws and bias the jaws toward their closed position. The U-shaped leg portions wedge the jaws together as the jaws approach their closed position, and prevent the jaws from being moved apart by a trapped animal.

Abstract: An apparatus for the activation of a gas-operated reloading mechanism of a firearm comprising a cylindrical cartridge magazine housing along with a pressure sensing and regulating means, using a series of three chambers and a moveable piston which regulates a pressure controlling valve. Gas pressure from an exploding cartridge in the barrel of the firearm is bled into a first chamber through a passage where it displaces a piston attached to a moveable tapered stem. The tapered stem protrudes into an orifice creating a valve combination which regulates the flow of gas into a chamber which activates the reloading mechanism. High or low pressures within the gun barrel are equally capable of operating the reloading mechanism with reliability and without damage to parts.
