US Patent:

50763962, Dec 31, 1991

Filed:

Aug 10, 1990

Appl. No.:

7/566084

Inventors:

John P. Foote - Marietta GA

International Classification:

B61K 300

US Classification:

184 31

Abstract:

A hydraulic master unit is mounted on the rail and has a master cylinder in which is mounted a plunger to be contacted by the wheel of the train. A master cylinder piston is driven against the compression of a cylinder spring inside the master cylinder body in which there is confined hydraulic fluid leading through a hydraulic line, through a hydraulic bulkhead assembly fitting and thence to a grease pump slave unit comprising a hydraulic grease pump piston operating against a grease pump spring inside of the grease pump housing in which there is a chamber confining the hydraulic fluid with the piston for operation to pump grease through the grease discharge and to draw grease from the grease container back into the slave cylinder and through a grease pump inlet valve against a grease pump inlet valve spring and so on in repetition in response to the contact of the master cylinder plunger by the train wheel.

Appl. No.:

5/772112

Inventors:

John P. Foote - Marietta GA

Assignee:

U.S. Armament Corporation - Gretna LA

International Classification:

F41C 1100

US Classification:

42 16

Abstract:

An automatic and semiautomatic small caliber conversion system for automatic or semiautomatic shotguns and rifles such as, for example, M-16 and AR-16 rifles, including a uniquely designed three element structure and associated ammunition feeding means to permit the use of smaller caliber, inexpensive ammunition in rifles and shotguns designed originally for larger caliber ammunition. The system includes a bolt/receiver assembly which easily replaces the bolt carrier of the, for example, M-16 rifle, and a magazine assembly which can be inserted by hand into any standard, for example, 0. 223 round M-16 magazine. The bolt/receiver assembly is made up of three sub-assemblies, a receiver, a bolt, and a recoil spring. The receiver sub-assembly includes a section of a circle with a short barrel section in the front which fits into the M-16 chambers, a receiver lug at top rear to locate it within the M-16 chamber and prevent its rotary or linear motions and a guide rail. The bolt sub-assembly is cylindrical in shape, is guided by the adapter receiver guide rail and is encompassed by the M-16 receiver so that its only free movement is front to rear for ejecting and chambering cartridges.

Appl. No.:

5/818460

Inventors:

John P. Foote - Marietta GA

International Classification:

F41C 1104

US Classification:

42 23

Abstract:

A single shot rifle comprises the usual elongated barrel of any desired calibre with the shell receiving end screwed into a receiver having spaced sides defining a passage for a cartridge to be inserted and removed therefrom. A falling breechblock is provided with a stock extension for insertion in and permanent mounting on a stock so that the breechblock and stock move together. The trigger mechanism, hammer and extractor mechanisms may be of any suitable and conventional construction including the usual cocking lever which actuates the spring biased hammer that is released by a trigger.
