Gun Mount Exerciser (Gme)
Gun Mount Exerciser (Gme)
US Patent:
5078045, Jan 7, 1992
Filed:
Jan 16, 1991
Appl. No.:
7/642245
Inventors:
Michael J. Audino - Albany NY
Gary Brownell - Tribes Hill NY
John Jorczak - Castleton NY
Victor Nerses - Albany NY

Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
F41A 2502, F41A 2526
US Classification:
89 4301
Abstract:
The invention is a gun mount exerciser to force a cannon through its recoil otion which otherwise occurs only when the cannon is fired. The exerciser includes a frame that rests on the outer casing that is fixed around the cannon. The frame is translated on a stationary member by actuation of a fluidically operated cylinder mounted to the stationary member. The frame is fixed to the outer casing of the gun so that translation of the frame effects translation of the outer casing and the cannon itself.

US Patent:
H2178, Feb 3, 1987
Filed:
Dec 24, 1984
Appl. No.:
6/685647
Inventors:
John K. Jorczak - Castleton NY
Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
F41F 1902, F41F 1914
US Classification:
89 4301
Abstract:
A hydraulic recoil mechanism, which may be used as a shock absorbing device ontrols both the recoil and counter-recoil motion of a cannon. Main recoil energy is dissipated via a movable cylindrical piston rod which pumps hydraulic fluid through a series of orifices into a primary chamber and is subsequently metered through an orifice effected by the traveling piston head and a fixed variable geometry control rod. A buffer spear arrangement integrated at the opposing end of the control rod dissipates final counter-recoil energy via a metering cavity contained in the returning piston. The piston rod assembly carries a ring-like floating piston which, upon recoil, closes a by-pass orifice and, upon counter-recoil, opens the by-pass orifice. A temperature compensator mechanism is also integrated into the system to accommodate thermal expansion of the fluid during sustained operation.
