Abstract
Abstract The releasable retention of an ammunition chute to the feedway of a gun is accomplished by a pair of oppositely biased plungers slidably retained on each side of the chute for engagement with corresponding sockets in outwardly extending brackets on each side of the gun feedway. Axial displacement of the plungers is effected by a lever pivoted thereto at one end and joined at the opposite end thereof to permit compensatory movement at substantially right angles to the direction in which the levers are actuated whereby the forces transmitted to the plungers are limited to the axis of displacement thereof to prevent concurrent sticking and binding.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
Latch means for releasably securing one end of an ammunition chute to the feedway of a gun, comprising, at least one fixed housing extending outwardly from a side of the chute, a pair of axially aligned plungers disposed in spaced apart relation and slidable in said housing, at least one bracket projecting outwardly from the gun feedway and having axially spaced sockets therein for releasably receiving the remote ends of said plungers, spring means engaging the adjacent ends of said plungers for axially biasing said remote ends into latching engagement with said sockets, a lever assembly comprising a pair of levers each having one end thereof pivotally secured to one of said plungers and with the opposite end thereof extending outwardly from said housing, and means for connecting the outwardly extending ends of said levers in a manner to permit lateral displacement of said outwardly extending ends in direct response to axial movement of said plungers whereby sticking or binding thereof in said fixed housing is avoided.
Claim 2
Dependent Claim
167 words
Latch means for releasably securing one end of an ammunition chute to the feedway of a gun, comprising, at least one fixed housing extending outwardly from a side of the chute, a pair of axially aligned plungers disposed in spaced apart relation and slidable in said housing, at least one bracket projecting outwardly from the gun feedway and having axially spaced sockets therein for releasably receiving the remote ends of said plungers, spring means engaging the adjacent ends of said plungers for axially biasing said remote ends into latching engagement with said sockets, a lever assembly comprising a pair of levers each having one end thereof pivotally secured to one of said plungers and with the opposite end thereof extending outwardly from said housing, and means for connecting the outwardly extending ends of said levers in a manner to permit lateral displacement of said outwardly extending ends in direct response to axial movement of said plungers whereby sticking or binding thereof in said fixed housing is avoided.
Claim 3
Dependent Claim
57 words
The combination defined in claim 1 wherein the outer ends of said levers terminate in an L-shaped configuration and said connection means therebetween comprises, a transversely stepped portion at the end of each L-shaped configuration, and a pivot pin extending transversely through the ends of said L-shaped configurations to join said transversely stepped portions in mating engagement.
Claim 4
Dependent Claim
57 words
The combination defined in claim 1 wherein said levers comprise oppositely facing strips of flexible metal terminating in vertical end portions disposed at substantially right angles to said strips for respective pivotal engagement with said plungers, and wherein said means for connecting said outwardly extending ends of said levers consists of a substantially U-shaped section integral therewith.
