Abstract: A Gatling gun with a magazine feed mechanism for use with a spring-loaded magazine. The magazine feed mechanism is configured to transfer spring-loaded rounds from the magazine into successive chambers of the plurality of chambers in the Gatling gun. The magazine feed mechanism chambers rounds from the spring-loaded magazine as the gun's bolt carrier rotates during firing.

Abstract: The present disclosure provides a pellet gun that comprises a gun and a cartridge. The cartridge is selectively positionable at the breach end of the barrel and includes an opening configured to selectively hold a pellet. The cartridge is also located inside the pellet gun such that when the cartridge is selectively holding the pellet the pellet is located in the barrel, and is selectively filled with a pressurized gas. The trigger initiates engagement with the cartridge to cause the gas in the cartridge to be exerted against the pellet which is fired through the barrel.

Abstract: A less-than-lethal pellet gun is provided. The gun includes a plurality of links each holding a pellet. A feed cylinder is configured to advance the links to a firing position and eject each link after its pellet has been fired. The feed cylinder includes a slot portion and a gear portion. The slot portion includes a first slot region, a second slot region, a first angled slot region, and a second angled slot region. A linkage arm is configured to engage the slot portion of the feed cylinder such that linear movement of the linkage arm rotates the feed cylinder to move the pellet to a firing position.

Abstract: An apparatus for launching a projectile, such as a paintball. The apparatus uses energy generated from the combustion of fuel to propel a projectile out of the apparatus.

Abstract: A device for driving various objects using combustible fuel. Embodiments are contemplated in which the driver could be a post-driver, a power shovel, a jack-hammer or other devices. Typically, the device includes a body with a combustion chamber. A fuel injection valve selectively supplies fuel to the combustion chamber where it can be ignited using an ignition module. A piston is movable within the body to impact the ram responsive to combustion in the combustion chamber.

Abstract: Apparatus for firing a projectile comprises a receiver, a barrel, a supply of combustible gas, a combustion chamber, a valve arrangement for controlling flow of combustible gas from the supply to the combustion chamber, an igniter, and a passageway for directing combustion gases from the chamber to propel a projectile from the apparatus. In one embodiment, the barrel has a longitudinally-extending central axis, and the combustion chamber is disposed laterally adjacent the axis. A method of operating the apparatus comprises the steps of providing a combustible mixture of gas and air to the combustion chamber, igniting the mixture so as to generate combustion gases, allowing pressure in the combustion chamber to increase to a predetermined level, and releasing the gases from the combustion chamber and directing the gases to propel the projectile through the barrel.

Abstract: Apparatus for working pliable material comprises a body, at least two rotatable shafts coupled to the body, an embossing assembly detachably coupled to an end of at least one of the shafts, and a cutting assembly and/or a creasing assembly being alternatively coupled to the end of the shaft in place of the embossing assembly. In one embodiment, the apparatus is powered by hand via a rotatable handle coupled to at least one of the shafts. The assembly may further comprise an adjustment wheel and an adjustment shaft for accomodating various material types.

Abstract: An ammunition feed mechanism for an automatic or semiautomatic weapon which includes a mechanism for retarding the cyclic feeding of ammunition into the chamber of the weapon. The mechanism for retarding the cyclic feeding of ammunition includes an impeder which engages the bolt of the weapon. The ammunition feed mechanism also includes a magazine having a ramped bottom which directs ammunition projectiles to an exit therein where the ammunition projectiles are fed into the chamber of the weapon. The magazine includes a plurality of curved projections in the bottom which define a plurality of spaces into which the ammunition projectiles are received. The plurality of curved projections also guide the ammunition projectiles through the exit.

Abstract: A manually driven stitcher or sewing machine. A lever of the stitcher is manually pivotable through an arc to reciprocate a stitching mechanism. When pivoted through the arc, the lever also actuates a clamping assembly, an article advancing mechanism, and a stitching material supplying assembly. The stitcher or sewing machine of the present invention may be used to manually stitch a variety of materials including heavier ones such as leather, nylon strapping, plastic, and rubber.
