Abstract: A tool for driving a nail or other fastener is actuated by a caseless propellant charge formed of combustible material that is transported into a combustion chamber on a strip. The propellant charge is ignited by striking a sensitizer portion of the charge at an oblique angle. The ignition member intermixes the sensitizer material with an oxidizer layer of the surface of the propellant charge, resulting in combustion of the charge. When ignited, the propellant charge is compressingly interposed between an orifice plate and a movable portion of the combustion chamber. The orifice plate includes a pedestal with an annular compression surface that separates the surface of the ignition area from the remaining surfaces of the charge, insuring that ignition gases are forced through the charge. An annular C-shaped ring is interposed between the orifice plate and the movable portion of the combustion chamber.
Abstract: A plastics cartridge has a cartridge body provided with a flange which has a plastic casing body, open on one side, is for accommodating a propellent charge and an ignition charge for igniting the propellant charge and has a plastics cover for closing the open end of the casing body. A flange is located on the end of the casing body on the cover side. if the cartridge body is inserted into the firing device, the flange extends into a space which passes out of a receiving chamber of a cartridge recess and is formed by cartridge recess and bottom of the breech of the firing device. In the section in which it extends in the propagation direction of the pressure wave arising on ignition of the propellent charge, the flange of the cartridge body is tapered--in the propagation direction--at least over a part of said section. The flange therefore forms a wedge which is inserted into the wedge-shaped space between the cartridge recess and bottom of the breech.
Abstract: A magazine for cartridges ignitable by adiabatic compression is especially useful for stud driving or setting tools. The magazine has a plurality of cartridges made of synthetic resin and a magazine belt made of synthetic resin for connecting the plurality of cartridges together. The magazine belt forms bottom walls of the cartridges and in the region of each of the bottom walls is provided with an intentional separation zone. A primer wafer is provided on the magazine belt in the region of the bottom wall near the intentional separation zone. Each primer wafer in an area near the intentional separation zone is thinner than in the remaining zone surrounding the area.

Abstract: A propellant strip assembly for use in propellant actuated fastener driving tools. The assembly includes a carrying strip which contains a plurality of pockets which each hold a propellant charge and a sensitizer to activate the charge. The carrying strip is adhesively joined to a cover strip to isolate the individual charges, and each pocket is also sealed around its periphery to further improve the isolation. The cover strip may contain a ribbed section to physically separate the charge and sensitizer within each pocket to aid in prevention of accidental ignition.
Abstract: A propellant containing device for a power actuated tool used to drive fasteners into concrete and the like. A cartridge member has an inner substantially cylindrical recess. The recess has an inner area and is filled with propellant. A cap closure member is used to seal the cartridge member and holds a detonator charge. An annular skirt formed integral with the cartridge member is located so as to act as one half of the anvil when the detonator charge is compressed between the annular skirt and the cap closure member using rim-fire techniques. The cap closure member and the cartridge member are made from a suitable plastic material.

Abstract: A propellant containing device for use in association with a gun with a detonator mechanism and drive mechanism for the purpose of driving an attachment member into a structure. The device has an elongate or circular base. A plurality of cartridge members are formed integrally with the base and each member contains an explosive charge. The base and the cartridge members are formed in one piece from a material selected from plastic or ceramic. The region of the cartridge members integral with the base are closed by a cap which is adapted to fit within a recess formed in the periphery of the closed ends of the cartridge members. The cap is adapted to be hit by the detonator mechanism to detonate an explosive charge located in the cartridge member. A drive engagement fitting on the base allows the base to be moved progressively so that each cartridge member aligns successively with the detonator mechanism of the gun.
Abstract: A magazine for caseless propellant charges, such as used in a fastening element setting device, consists of an elongated strip-like member. Cut-outs are provided in the strip-like member and a caseless charge holder is secured in each cut-out by webs. A caseless charge and the holder are displaced out of a cut-out when a sufficient force is directed against the holder to separate the webs from the strip-like member.
Abstract: Ammunition for a toy-weapon comprises an injection moulded support having seats for explosive charges. The charges are sealed within the seats by a separate cover for each seat. The covers are injection moulded simultaneously onto the seats of the support.
Abstract: A toy gun of the revolver type which is capable of employing various types of ammunition and incorporating in the head of the cylinder a plurality of chambers having a rod in each chamber functioning as a percussion anvil for cup like ammunition, and including at least a perimetral non-circular shoulder inscribed in a polygon. The number of the sides of the polygon is a submultiple of the anvils to assure the angular positioning of a laminar ammunition. The laminar ammunition is a sandwich construction with explosive charges held between two layers and spaced from each other angularly and radially from the center so as to conform with the anvils of the gun and presents a profile of its external perimeter and/or of a central hole to complement a corresponding profiled shoulder associated with the cylinder head of the gun to position the charges on the anvils.
Abstract: Ammunition for a toy revolver comprises a disk structure provided with a plurality of angularly equispaced capsules containing explosive charges (rounds) and adapted to register with anvils of a barrel for firing. The number of capsules is twice that of the number of seats within which each of the anvils is provided. The side of the disk opposite the percussion side is formed with at least two projections each of which is adapted to engage in one of the seats between a wall thereof and the anvil. Thus the projections lie to one side of the anvil during the firing of alternate capsules and the disk can be angularly spaced relative to the barrel to dispose the projections on the opposite sides of the respective anvils and cause the remaining capsules to be aligned with the anvils and to be fired.
