Abstract
Abstract A clamp and wedge attachment to fixed and moving components frictionally ages the components which become disengageable upon application of overriding forces. The wedge has an enlarged detachable loading end which fits between two tines of the clamp which acts as flexure springs. This structure eliminates the slide bounce problem encountered in adapting the M39, 20MM Automatic Revolver Cannon to a constant recoil mode of operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
116 words
A clamp and wedge attachment between relatively fixed and moving components for releasably maintaining said components in fixed relationship until subjected to overriding forces, said relatively fixed and moving components being a gun receiver and an operating slide for chambering cartridges, said clamp having a pair of spaced tines between which said wedge frictionally moves as said slide moves forwardly to battery position, said tines having inner tapered surfaces for continuously contacting said wedge when said wedge is inserted therebetween, said clamp having a base to which said tines are connected, said tines having a reduced portion adjacent said base forming a flexure spring opening and allowing said tines to snap tightly closed on said wedge.
Claim 2
Dependent Claim
116 words
A clamp and wedge attachment between relatively fixed and moving components for releasably maintaining said components in fixed relationship until subjected to overriding forces, said relatively fixed and moving components being a gun receiver and an operating slide for chambering cartridges, said clamp having a pair of spaced tines between which said wedge frictionally moves as said slide moves forwardly to battery position, said tines having inner tapered surfaces for continuously contacting said wedge when said wedge is inserted therebetween, said clamp having a base to which said tines are connected, said tines having a reduced portion adjacent said base forming a flexure spring opening and allowing said tines to snap tightly closed on said wedge.
Claim 3
Dependent Claim
38 words
A clamp and wedge attachment as set forth in claim 1 wherein said wedge is of a constant thickness, said wedge having an enlarged end fitting between said tine reduced portions when said slide is in battery position.
Claim 4
Dependent Claim
43 words
A clamp and wedge attachment as set forth in claim 2 wherein said tines have shoulders thereon engagable by said enlarged end to prevent dislodgement of said wedge from said clamp tines until firing of said gun upon which said attachment is mounted.
Claim 5
Dependent Claim
38 words
A clamp and wedge attachment as set forth in claim 1 wherein said tines have inclined surfaces on the ends thereof and said wedge has an end surface engagable therebetween upon insertion of said wedge between said tines.
Claim 6
Dependent Claim
43 words
A clamp and wedge attachment as set forth in claim 1 wherein said slide closes an electrical switch in the gun firing circuit when said slide is in battery position, said attachment maintaining said slide in battery position until said gun is fired.
