Claims
- 1. Apparatus for manipulating resilient retaining rings or the like, comprising:
- (a) a pair of handles operatively connected to a pair of movable jaw members;
- (b) a pair of ring engaging tips each associated with a different one of said jaw members;
- (c) a pair of clamping plate members each secured to an associated jaw member, each plate member including a portion overlying a portion of the associated jaw member;
- (d) a first of the associated members of each associated pair including tip surfaces for engaging complemental surfaces of said associated tip;
- (e) at least one member of each pair of associated members including a projection for engaging the other member of the associated pair at a location remote from an outward end of said tip surface; and,
- (f) each of said clamping plate members including an aperture by which said clamping plate is secured to its associated jaw member by a fastener, said aperture being located such that an imaginary line extending between said projection and said aperture intersects the outward end of an associated tip surface.
- 2. The apparatus of claim 1 wherein each of the second of the members of each associated pair also includes tip engaging surfaces for engaging further complemental surfaces of said associated tip.
- 3. The apparatus of claim 1 wherein said at least one member of each pair is the plate member.
- 4. A plier tool comprising:
- (a) a pair of articulatable jaw members;
- (b) a pair of handles operably connected to the jaw members for selectively effecting jaw articulation;
- (c) a pair of tips respectively associated with the jaw members, each tip including at least one workpiece engaging surface near its outer end;
- (d) a clamp member associated with each jaw member, said clamp member and associated jaw member together defining a clamping assembly;
- (e) said clamping assembly defining a recess for receiving a section of the associated tip;
- (f) fastening means for generating a clamping force in said clamping assembly; and,
- (g) each clamping assembly including structure establishing a fulcrum at a location opposite a location of fastening means application and constructed to cause the greatest clamping force application to an associated tip to be on a portion of the tip section nearest the outward end of said recess whereby twisting of said tip section in said clamping assembly is substantially inhibited.
- 5. In a ring manipulating tool, an improved jaw assembly comprising:
- (a) a pair of articulatable jaw members;
- (b) a pair of tips respectively associated with the jaw members, each tip including at least one workpiece engaging surface near its outer end;
- (c) a clamp member associated with each jaw member, said clamp member and associated jaw member together defining a clamping subassembly and a recess for receiving a section of an associated tip;
- (d) fastening means for generating a clamping force in said clamping subassembly whereby said section of the associated tip is clamped between the clamping member and jaw member; and,
- (e) each clamping subassembly including structure establishing a fulcrum at a location opposite a location of fastening means application and constructed to cause the greatest clamping force application to the associated tip to be on a portion of the tip section nearest an outer end of said recess whereby twisting of said tip section in said clamping assembly is substantially inhibited.
- 6. The apparatus of claim 5 wherein said fulcrum established by each clamping subassembly is formed by a portion of said clamp member that is bent towards said associated jaw member.
