Patent ID: 8234978

Claim:
A firing device, comprising: a first hollow cylinder; a second hollow cylinder laterally spaced from and extending substantially parallel to the first hollow cylinder, each of the first and second hollow cylinders having a longitudinal axis, an inner surface and an outer surface, and extending longitudinally between a first end and a second end, each said first and second hollow cylinders is further formed with an elongated opening through a side wall of each of said hollow cylinders; a spring disposed in each of the first and second hollow cylinders; a firing pin disposed in each of the first and second hollow cylinders, wherein each spring is positioned between the first end of one of the first and second cylinders and the respective firing pin; a lever structure having a first and second portion, said second portion having a section formed with a first and second elongated aperture, said lever structure is coupled to the firing pins via at least one fastener which couple said lever structure to the firing pins, said firing pins are disposed in each of the first and second hollow cylinders through said elongated openings in the first and second hollow cylinders, the lever structure positioned outside of the first and second hollow cylinders and configured to move longitudinally in response to movement of the firing pins; a first bushing disposed between a first portion of the lever structure and the first hollow cylinder, the first bushing interposed within the opening of the first hollow cylinder; and a second bushing disposed between the second portion of the lever structure and the second hollow cylinder, the second bushing interposed within the opening of the second hollow cylinder; wherein said first and second bushings further comprise a radial flange located between a first end and a second end of said first bushing, said flange being disposed on the bushing between a bottom of said lever structure and said outer surface of said hollow cylinders such that frictional contact is eliminated between the first and second hollow cylinder and the lever structure, said second end of said first and second bushing are respectively positioned in contact with a mating surface of said first and second firing pins; wherein said elongated openings, elongated apertures, said fasteners, said bushings are sized to permit said lever structure to permit the firing pins to move within said hollow cylinders significantly independent of mechanical force interference from one firing pin to the other firing pin as well as permitting said firing pins to be positioned substantially ahead or rearward of each other including where one pin is fully forward against a stop and the other pin is fully rearward against said springs respectively disposed in each said hollow cylinder.
