Abstract
Abstract A support base defining a generally planar abutment surface and having an abutment member pivotally supported therefrom for oscillation relative to the base. The abutment member includes an arcuate surface extending about the axis of oscillation of the abuement member and including adjacent longitudinally spaced portions spaced progressively further from the axis of oscillation of the abutment member and progressively moveable into closer proximity with the abutment surface of the base in response to pivotal movement of the abutment member in one direction so that a clamping or crimping force may be directed upon a workpiece disposed between the abutment member''s arcuate surface and the abutment surface of the base when the base is supported from the housing of an impact gun having its reciprocal impact member disposed for engagement with the abutment member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
144 words
In combination, a base defining a first abutment surface having a first marginal edge, a cam abutment member supported from said base for oscillation about an axis generally paralleling said edge, spaced from said surface and spaced inwardly from said edge, said cam member including a second slightly arcuate convex abutment surface spaced from, opposing and generally paralleling said first abutment surface, curving about said axis and including portions spaced angularly therealong in one direction toward said edge spaced increasing distances from said axis, said base including a mounting portion spaced outwardly of said axis from said base first abutment surface and having an opening formed therethrough extending generally normal to said axis and generally paralleling said first abutment surface, said cam member including a portion registered with one end of said opening for impact thereon by an impact member reciprocated through said opening.
Claim 2
Dependent Claim
144 words
In combination, a base defining a first abutment surface having a first marginal edge, a cam abutment member supported from said base for oscillation about an axis generally paralleling said edge, spaced from said surface and spaced inwardly from said edge, said cam member including a second slightly arcuate convex abutment surface spaced from, opposing and generally paralleling said first abutment surface, curving about said axis and including portions spaced angularly therealong in one direction toward said edge spaced increasing distances from said axis, said base including a mounting portion spaced outwardly of said axis from said base first abutment surface and having an opening formed therethrough extending generally normal to said axis and generally paralleling said first abutment surface, said cam member including a portion registered with one end of said opening for impact thereon by an impact member reciprocated through said opening.
Claim 3
Dependent Claim
26 words
The combination of claim 1 wherein said mounting portion comprises a mounting flange generally paralleling said marginal edge and projecting outwardly from said first abutment surface.
Claim 4
Dependent Claim
54 words
The combination of claim 2 wherein said base includes a pair of generally parallel plates secured between said flange and said first abutment surface adjacent to junction between said flange and said first abutment surface disposed generally normal to said marginal edge, said cam member being disposed between said plates and oscillatively supported therefrom.
Claim 5
Dependent Claim
20 words
The Combination of claim 1 wherein the junction between said marginal edge and said first abutment surface is convexly radiused.
Claim 6
Dependent Claim
250 words
In combination, a base defining a first abutment surface having a first marginal edge, a cam abutment member supported from said base for oscillation about an axis generally paralleling said edge and spaced outwardly of said surface, said cam member including a second arcuate convex abutment surface curving about said axis with portions of said arcuate abutment surface spaced angularly therealong in one direction being spaced increasing distances from said axis, said base including a mounting portion spaced outwardly of said axis from said base first abutement surface and having an opening formed therethrough extending generally normal to said axis and generally paralleling said first abutment surface, said cam member including a portion registered with one end of said opening for impact thereon by an impact member reciprocated through said opening, said mounting portion comprising a mounting flange generally paralleling said marginal edge and projecting outwardly from said first abutment surface, said base including a pair of generally parallel plates secured between said flange and said first abutment surface adjacent to junction between said flange and said first abutment surface disposed generally normal to said marginal edge, said cam member being disposed between said plates and oscillatively supported therefrom, including a mounting sleeve secured to said flange about said opening and projecting outwardly of the side of said flange remote from said marginal edge, said mounting flange being adapted to be supported from the sleeve portion of an impact gun through which the impact member of the gun is reciprocal.
Claim 7
Dependent Claim
250 words
In combination, a base defining a first abutment surface having a first marginal edge, a cam abutment member supported from said base for oscillation about an axis generally paralleling said edge and spaced outwardly of said surface, said cam member including a second arcuate convex abutment surface curving about said axis with portions of said arcuate abutment surface spaced angularly therealong in one direction being spaced increasing distances from said axis, said base including a mounting portion spaced outwardly of said axis from said base first abutement surface and having an opening formed therethrough extending generally normal to said axis and generally paralleling said first abutment surface, said cam member including a portion registered with one end of said opening for impact thereon by an impact member reciprocated through said opening, said mounting portion comprising a mounting flange generally paralleling said marginal edge and projecting outwardly from said first abutment surface, said base including a pair of generally parallel plates secured between said flange and said first abutment surface adjacent to junction between said flange and said first abutment surface disposed generally normal to said marginal edge, said cam member being disposed between said plates and oscillatively supported therefrom, including a mounting sleeve secured to said flange about said opening and projecting outwardly of the side of said flange remote from said marginal edge, said mounting flange being adapted to be supported from the sleeve portion of an impact gun through which the impact member of the gun is reciprocal.
