Abstract: A bullet is fired from an ammunition cartridge upon piercing a breakaway section in the rear wall of the cartridge to form a gas escape port. The cartridge has one open end in which is seated the bullet and the breakaway section of the rear wall is directly opposite the bullet. A moveable sealing element is adapted to move between two positions. One position seals off the opening in the one end, and the other position is displaced from the opening to allow gas to escape under pressure from the opening. Piston-type element, in response to the housing wall being pierced, stops the flow of gas from this escape port and moves the sealing element from the first to the second position.

Abstract: A single-action, gas powered repeating pistol has a sliding unitary barrel and hammer assembly with the barrel and hammer aligned on opposite sides of a fixed pressure chamber. In the uncocked condition, the hammer extends rearwardly of the main frame so that cocking may be effected by merely slapping the rear of the hammer to force the assembly forward to be retained by a trigger mounted sear.

Abstract: A casting rod includes an elongated piston chamber tube and a connected guide tube for enclosing and guiding a push rod to accelerate and project a fishing lure or other weighted device attached to a line. The push rod has a piston fixed to its rearward end for coaction with the chamber tube, and the rod projects through the guide tube having a mounting tube at its exterior exposed end which is the rod tip. A weighted device has an axial pin received within the mounting tube and attached to the line which passes through a line aperture in the mounting tube. The rod includes a valve housing and handle at its base end, the handle enclosing a CO.sub.2 cartridge which is pierced to pressurize the valve chamber. A valve interposed between the valve chamber and the cylinder chamber is opened momentarily by a firing pin impacted by a hammer to pass a charge of pressurized gas to the piston chamber to accelerate the push rod and project the lure.

Abstract: A gas-powered gun includes a movable loader for moving projectiles into alignment with the barrel of the gun and a detent engageable with the loader for retaining a protectile in the firing position. The loader is provided with projectile ports for holding the projectiles, and the detent is engageable with each port as it moves into alignment with the barrel. The detent is slidably mounted within a detent holder, and the detent holder is connected to a source of pressurized gas. A gas passage extends through the detent, and when the gun is fired, pressurized gas flows through the detent and propels the projectile through the barrel.

Abstract: A gas-fired gun having a handgrip defining a chamber for receiving a gas-containing cartridge and a lever coupled to the handgrip at its lower end for pivotal movement between positions opening and closing the chamber. The lower end of the lever carries a seat on opposite sides of which are first and second cam surfaces. The first cam surface cams the cartridge into an operative position in the chamber with its upper end in engagement with a cartridge piercing mechanism upon movement of the lever from the first to the second position. The seat enables the cartridge to back off the piercing mechanism when the lever is in the second position to improve the gas flow from the cartridge into the gas-fired gun. The second cam surface displaces the cartridge from the chamber upon movement of the lever from the second position toward its first position.

Abstract: The plastic valve includes an elongated plastic valve stem and an elongated pin. An end portion of the pin projects from an end of the plastic stem with the remaining portion of the pin being wholly encapsulated by the stem. The pin is generally cylindrical and has a pair of reduced diameter portions defining shoulders forming impact surfaces which butt the axially opposed portions of the encapsulating stem. The stem preferably has a tapered sealing surface irradiated by beta rays to provide a sealing surface highly resistant to creep and deformation. The sealing surface is coated with Fluorocarbon Polymer to reduce its chemical activity and to improve its sealing characteristics. The opposite end of the pin serves as a deflector opposite the molding gate to control the flow of plastic material during injection molding of the stem to prevent weld lines on the seal surface.

Abstract: Disclosed is a safety for the trigger mechanism of a gas powered gun including a safety lever, and a safety latch. The gun has a trigger mechanism including a trigger pivotably carrying a sear on a sear pivot pin, and a hammer engageable by the sear for opening a valve and releasing gas under pressure to propel a projectile from the gun barrel. The safety lever, safety latch, trigger and sear pivot pin have cooperating cam surfaces which return the safety latch to a safe position upon partial movement from its safe position toward a fire position; return the safety latch to its safe position upon partial squeezing and release of the trigger; return the safety latch and the safety lever to the safe position upon each firing of the gun whereby repeat firing is prevented; prevent repeat firing of the gun in the event the safety lever is continuously biased toward the fire position; and prevent firing of the gun when the safety lever is rigidly maintained in its fire position.

Abstract: Disclosed is a gas fired gun having a valve body for communicating gas under pressure from a gas cartridge to the gun barrel to fire a projectile. The gun has a frame carrying a chamber for receiving a gas cartridge and a lever for urging the cartridge in the chamber against a conical element carried in a stepped bore in the valve body. A retainer ring having triangular shaped projections disposed in a direction toward the tip of the conical element is provided about the element. A seal seats on a stepped shoulder in the bore and a retainer nut bears against the seal which, in turn, bears against the triangular projections on the ring to retain the conical element in the bore. Upon actuation of the lever, the end of the cartridge is fully inserted into the bore and pierced by the element. When the lever is in final position, the cartridge backs off the piercing element to enable gas flow through the seal between the projections of the retainer ring and the element into the valve body passage.

Abstract: A projectile is propelled from the gun when a valve that controls the gas storage chamber of the gun is momentarily unseated, thereby admitting a short burst or charge of gas into the space immediately behind the projectile. The barrel that confines and controls the projectile during its movement out of the gun is itself driven rearwardly by spring action to accomplish unseating of the valve through an actuating stem at the rear of the barrel, and during such rearward movement of the barrel, the projectile is carried therewith so as to reduce the volume of the space behind the projectile in which the gas may expand before acting upon the projectile.

Abstract: A pressured gas or air operated repeater rifle which enables safe and accurate firing regardless of the rapidity of firing. A barrel of the rifle is provided with a bolt arranged slidably in a bore and a carrier which is positioned so as to extend through the bore at horizontal right angle to the bolt and to be slidable in the barrel and which is in freely sliding contact with a magazine opening at horizontal right angle to the direction of the magazine chamber. The carrier is provided with a lateral through hole at a position to match the opening of the magazine when the carrier shifts to the magazine side, and also to match the bore when it shifts in the direction opposite to the magazine side. An operation bar which connects the bolt with an operation bar handle on the cylinder is provided. Reciprocating movement of the carrier is provided by a mechanism positioned in the gap between the bolt and the hammer chamber arranged above and below.

Abstract: A rapid-fire B.B. pellet-type machine gun operated from a source of gas propellant preferably a canister of liquefield gas, has a trigger-operated valve releasing propellant gas from the source to a pellet containing magazine for projecting the pellets in rapid succession through a barrel passageway to be ejected from the gun at high speed at a target to which the gun is pointed. The pellets underlie and surround a sleeve in the magazine acting as a cofferdam to maintain a local level of the pellets below the gas inlet and the gas outlet so that the gas will impinge against and actuate the pellets causing them to be successively swept into the gas outlet for discharge through the barrel.

Abstract: Disclosed is an air rifle having a frame carrying a barrel, a magazine, a mechanism for transferring BB shot from the magazine to a firing position relative to the barrel, a valve, a gas cartridge loading assembly, and a trigger for momentarily opening the valve enabling gas under pressure from the cartridge to fire the BB shot from the rifle. The magazine includes a tube carried along the underside of the barrel. A spring-biased rod is carried within the tube and urges BB shot along the tube toward the transfer mechanism. An aperture in the tube opens into a passage in the frame and which passage terminates along the underface of the forearm stock in a recess having tapered wall portions whereby, upon inversion of the rifle, BB shot supplied to the recess is directed through the passage into the tube. The forearm stock also has a recess along its underside for receiving the gas cartridge.
