First Claim
1. A machine gun for cartridges having rims with a diameter greater than the body of the cartridges including, a receiver having a reciprocating bolt and provided with an upwardly facing cartridge feeding access area adjacent the opening to the chamber of a barrel connected to said receiver, a feed block having a cartridge throat therethrough disposed within said access area and provided with a main body having at least a portion thereof straddling the top of said bolt when said bolt is in its forwardmost position of travel, a cartridge magazine mounted atop said gun and including a bottom facing cartridge exit overlying said feed block throat, drive means within said magazine sequentially urging cartridges under pressure through said exit to said feed block throat, fixed and displaceable stop means in said block bounding said throat for supporting in a forwardly downwardly inclined manner each cartridge being urged from said magazine exit for subsequent delivery by said bolt into said chamber, said fixed stop means including a pair of oppositely disposed ledges adjacent the rear of said throat and extending transversely into said throat to support there-atop only the rim of a cartridge, said displaceable stop means including a pair of oppositely disposed moveable flange members disposed below the plane of said fixed rim ledges each having an inwardly projecting lip normally extending only into the forward area of said throat, spring means constantly urging said lips into said throat and said spring means resists the pressure of said drive means and supports each cartridge in said inclined manner upon said lips until subsequent downward and forward delivery of said cartridge into said chamber by said bolt.

Abstract
A machine gun includes a feed block removably mounted intermediate a cartridge magazine and the gun receiver and which is provided with self-contained movable flange members adapted to support the lowestmost cartridge being delivered to the feed block yet which flange members yield to the force of the closing gun bolt as the bolt strips the cartridge from its captive position within the feed block and guides it into the chamber. The gun shoulder stock, receiver, receiver cover and feed block are constructed in a manner to facilitate instantaneous field disassembly of these components without the need for any tools while a bolt operating handle is provided which is of the free floating type, i.e. does not reciprocate during continuous firing of the gun.
