Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A locking plate assembly for a brake retractor mechanism comprising a rigid clamping member having an opening through which a retractor rod is disposed, means to tilt said clamping member relative to said rod to bring a pair of opposing edges of said opening into clamping engagement with the face of said rod, at least one of said pair of opposing edges having a tiltcompensating member mounted thereon for turning movement relative to said clamping member, said compensating member having a surface for frictional clamping engagement with said rod and said surface contacting said rod at spaced-apart positions to provide a turning movement of said compensating member until there is conformance of said surface with the face of said rod as said pair of opposing edges are urged together upon tilting of said clamping member.
Claim 2
Dependent Claim
135 words
A locking plate assembly for a brake retractor mechanism comprising a rigid clamping member having an opening through which a retractor rod is disposed, means to tilt said clamping member relative to said rod to bring a pair of opposing edges of said opening into clamping engagement with the face of said rod, at least one of said pair of opposing edges having a tiltcompensating member mounted thereon for turning movement relative to said clamping member, said compensating member having a surface for frictional clamping engagement with said rod and said surface contacting said rod at spaced-apart positions to provide a turning movement of said compensating member until there is conformance of said surface with the face of said rod as said pair of opposing edges are urged together upon tilting of said clamping member.
Claim 3
Dependent Claim
31 words
A locking plate assembly according to claim 1 wherein said compensating member is mounted for relative turning movement about an axis perpendicular to the plane in which said clamping member tilts.
Claim 4
Dependent Claim
26 words
A locking plate assembly according to claim 2 wherein said compensating member is connected to said clamping member by a pivot pin disposed along said axis.
Claim 5
Dependent Claim
34 words
A locking plate assembly according to claim 1 wherein said surface for frictional clamping engagement with said rod has straight edges which engage a flat face of said rod to provide maximum clamping forces.
