Patent number: 5749509Abstract: 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.Type: GrantFiled: June 5, 1995Date of Patent: May 12, 1998Assignee: SencorpInventor: David L.
