Abstract: A fastener applying tool is disclosed, powered by the gases produced from internal combustion of a fuel and air mixture. A piston connected to a fastener driver is slidably mounted within a cylinder to move reciprocally downwardly and upwardly through a driving and a return stroke. A combustion chamber is formed at the upper end of the cylinder. A compression chamber is formed at the lower end of the cylinder. A spark plug powered by a piezo-electric firing device, is located within the combustion chamber. The combustion chamber features a set of fan blades driven by an electric motor which is continuously in operation when the tool is in use. A main valve mechanism actuated by a set of lifting rods which are moved upwardly and downwardly when the tool is moved toward and away from the workpiece, is used to control the flow of fresh air through the combustion chamber. When the combustion chamber is isolated from the atmosphere and the fuel and air are thoroughly mixed, the spark plug is fired to explode the fuel and air mixture and force the piston through its driving stroke. The rapid discharge of combustion gases at the end of the driving stroke produces a thermal vacuum within the combustion chamber. Additional air supplied to the lower face of the piston from the atmosphere forces the piston through its return stroke.

Title: Improvements in Detonating Fuses for Projectiles.

IPC: F42C15/20
Filed: 1919-01-02
Abstract: 136,318. Adelman, A. Jan. 2, 1919. Projectile fuses.-Relates to fuses comprising a detonator such as 14 normally situated in an air chamber 10 away from a secondary detonator or booster charge 12 to prevent accidental transmission of explosion. According to the invention, centrifugal means, such as spring-pressed bolts 16, for preventing the arming, are combined with means for allowing the percussion rod 13, when freed by the centrifugal safety-device, to advance freely until checked by a spring abutment 18 which yields on impact. The advance cf the percussion rod brings the detonator 14 within the booster charge 12, and, when the priming-cap 15 strikes the firing-pin 17, the flash is tiransmitted to the detonator 12 with a certain delay. Rebound of the percussion rod is prevented by balls 21 which escape from an annular channel in the percussion rod into the wider portion of the fuse body beyond the shoulder 22. The spring abutment 18 is locked during transit by a pin 20. In a modification, the priming-cap 15 is situated within the percussion rod and transmits the flash without delay; and the firing- pin 17 is' lengthened to reach it.
