Abstract: The present invention relates to improvements in firing and cocking mechanism of a breach loading firearm. This invention utilizes a substantially massive pin block disposed in a horizontal track between two counter biasing springs, the main spring and the counter spring. A firing pin extends from the chamber end of the pin block. When the cocked pin block is released, the main spring drives it toward the chamber and the momentum of the moving pin block carries the extended firing into contact with the primer of the cartridge despite the resistance of the counter spring. Lowering the breechblock allows a spring loaded ejector plate to spring backward and pull the spent cartridge casing from the chamber. In addition the ejector plate strikes a projection of the pin block and drives the pin block back to the cocked position. An extension of a lever which operates the action returns the ejector plate to the chamber so that the breechblock is able to rise unobstructed.

Abstract: A trap for capturing animals comprising a main box, step boards, doors and anchoring members. The step boards are pivotally held to the main box, and the anchoring members attached to the step boards are designed so as to keep the doors open by anchoring them. When the step boards are pressed down by the weight of an animal passing through the main box, the doors are released from the engagement with the anchoring members and caused to close the entrances to confine the animal in the main box. Since the animal trap of the invention needs no bait for capturing an animal, it may be set up without any difficulty on the running route of the animals.

Abstract: A feed-holding member entices fish into a fish-trapping device which has an "exit only" closure for an outlet opening thereof. A "live net" is connected to that fish-trapping device adjacent that outlet opening, and, when the fish have satisfied their appetites, they will attempt to escape from the fish-trapping device. In doing so, the fish will open the "exit only" closure and pass through the outlet opening into the "live net"--which will hold the fish until they can be removed from that "live net".
