Abstract: A firing pin assembly of a nail gun and a bonding method thereof are provided. The firing pin assembly includes a firing pin body and a firing pin head made of a material having a hardness greater than that of the firing pin body. The firing pin head has a first end and a second end. The first end is made of a material having a density lower than that of the second end. The first end and the front end face of the firing pin body are preheated to a set temperature. The top of the second end is pressed toward the front end face of the firing pin body for an appropriate bonding time, so that the material particles of the firing pin body are dissociated and fused into the first end of the firing pin head to form the firing pin assembly.

Abstract: The invention is a multi-directional reactive pendulum object that is intended to be attached to any moving object such as the dashboard of a motor vehicle. The object is put into motion by the movement of the vehicle causing a pendulum to swing. The pendulum operates two levers that are on pivots which are perpendicular to each other. The object entertains occupants by mimicking the actions of the movement of the vehicle (i.e. turning left, right, stopping, accelerating). Placed on top of the pendulum object will be a toy consisting of various characters, models, or artistic renderings of existing items such as a car, motorcycle, or airplane.

Abstract: Semi-automatic rimfire rifles have a frame, a bolt operable to reciprocate within the frame, the bolt defining a bolt axis, the bolt defining a firing pin passage, a first firing pin portion received within at least a first portion of the firing pin passage, a second firing pin portion separate from the first firing pin portion received within at least a second portion of the firing pin passage, and the first firing pin portion being operable to contact the second firing pin portion such that the second firing pin portion discharges a cartridge in response to the first firing pin portion being struck by a hammer. The first firing pin portion may define a first firing pin axis aligned with the bolt axis. The second firing pin portion may have a nose portion that is offset from the bolt axis extending away from the first firing pin portion.

Abstract: A launcher which can be readily converted for use by either a right-handed or left-handed shot. The launcher has a receiver with upper and lower extensions extending forwardly from the receiver body. A barrel is pivotally mounted near forward portions of the extensions, in one of two positions, such that in one position it is pivotable from a home position aligned with the receiver and the extensions between the two extensions, to a load position with the breech of the barrel to the left, and such that in the other position it is pivotable from the home position, to a load position with the breech to the right. One way of accomplishing this is with a barrel support bracket to which the barrel is pivotally mounted, with the barrel support bracket being secured at or near the front of the receiver extensions, and being rotatable between two positions, each corresponding to a different swing direction for the barrel.

Abstract: An optical device controller in the type of imitative gun, which comprises a trigger-like portion, a barrel-like portion having a muzzle-like opening, a gas passage forming portion fixed in connection with a rear end of the barrel-like portion for providing a gas passage formed therein, a grip portion in which a gas chamber and a gas leading passage for leading a gas from the gas chamber to the gas passage formed in the gas passage forming portion are provided, an optical device positioned in the barrel-like portion to face the outside through the muzzle-like opening, an operation controlling portion for sifting the optical device from an inoperative condition to an operating condition in response to movement of the trigger-like portion, a movable valve provided on the gas leading passage for controlling the gas leading passage to be open in response to the movement of the trigger-like portion, and a sliding member having a pressure receiving portion formed therein to be positioned at the back of the barrel-l

Abstract: Semiautomatic pistol which is small enough to be carried in a pocket or otherwise concealed on the body of a person, and caseless ammunition for use in the pistol. The pistol has a grip adapted to be held in the hand of a shooter, a barrel extending in a forward direction from the grip, a closed chamber at the rear of the barrel, means for firing a caseless cartridge in the chamber with the entire cartridge being discharged through the barrel, and means responsive to the firing of the cartridge for opening the chamber and loading another cartridge into the chamber. The caseless cartridge consists of a hollow projectile filled with gunpowder, and a primer for igniting the powder. The primer is mounted directly to the projectile, and there is no casing or other material to ejected from the chamber before another round is loaded.

Abstract: A Quick Muzzle Loading Rifle is provided that consists of a barrel extension that is threaded into a frame and a short barrel that is pivotally attached to the frame and can pivot between a position in-line with the barrel extension and a position to the side of the frame. When pivoted to the side of the frame, the short barrel is loaded. Once loaded, the short barrel is placed in-line with and forced toward the barrel extension which causes the short barrel to contact a gas seal that ensures leak-tight communication between the short barrel and the barrel extension. While in this configuration, the Quick Muzzle Loading Rifle is capable of being fired. A Quick Loader functions to load the Quick Muzzle Loading Rifle and consists of a main cylinder, a cylinder top, and a cylinder base. The main cylinder bounds, in its interior, a plurality of cylindrical storage cavities.

Abstract: A hypodermic dart gun of the firearm type includes a user-adjustable valve for regulating the feed rate of high pressure combustion gases from an exploded blank cartridge into the breech end of a gun barrel containing a hypodermic dart whereby the velocity of the ejected dart, and hence its effective range, is controlled. A pivotally mounted breech block for receiving the blank cartridge includes a baffle element for generating high combustion gas temperatures and pressures to ensure complete burning of the smokeless type gunpowder used in conventional blank cartridges. The adjustable valve forms a part of the breech block and is comprised of a high-temperature-resistant metering orifice whose cross-sectional area is determined by the position of a threaded member turnable in screwlike fashion into and out of a bore in a wall of the breech block.
