Abstract
Abstract A rotor for a caliper brake and rotor therefor is provided with apposed chamfers adapted to seat over a flange on a wheel hub and the rotor is attached to the flange with the flange seated in one or the other of the chamfers. Thus, when the rotor is attached in one position, it is closer to the hub than when it is attached in the other position. A single rotor therefore is adapted to fit a plurality of different caliper brakes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
79 words
In a caliper brake comprising a hub and a rotor, the combination of a hub having an annular rotor-attaching flange and a rotor having apposed annular chamfers complementary to said annular flange and means for attaching said rotor to said flange with the said flange in one of said chamfers, said chamfers being off center so that when the rotor seated in one chamfer it is closer to the hub than when it is seated in the other chamfer.
Claim 2
Dependent Claim
79 words
In a caliper brake comprising a hub and a rotor, the combination of a hub having an annular rotor-attaching flange and a rotor having apposed annular chamfers complementary to said annular flange and means for attaching said rotor to said flange with the said flange in one of said chamfers, said chamfers being off center so that when the rotor seated in one chamfer it is closer to the hub than when it is seated in the other chamfer.
Claim 3
Dependent Claim
99 words
The caliper brake of claim 1, in which the rotor comprises two parallel annular wear faces, the first of which has a smaller inside diameter than the second and both of which have the same outside diameter and in which the chamfers are on apposed outside and inside faces of said first named annular wear face and have a diameter less than that of the inside diameter of the second annular wear face, whereby the second annular wear face can pass over the annular flange of the hub in seating the flange on the chamfer on said inside face.
Claim 4
Dependent Claim
95 words
The caliper brake of claim 2, in which said annular flange comprises a flat face normal to the axis of said hub and a rim surrounding said flat face normal thereto and in which said annular chamfers comprise apposed inset faces normal to the axis of said rotor and a shoulder surrounding each said inset face and normal thereto, said shoulders being complementary to said flat face, whereby when the flat face of said hub is seated against an inset face, the shoulder surrounding that inset face is seated on the rim of said flange.
Claim 5
Dependent Claim
104 words
The caliper brake of claim 1, in which said annular flange comprises a flat face normal to the axis of said hub and a rim surrounding said flat face normal thereto and in which said annular chamfers comprise apposed inset faces normal to the axis of said rotor and a shoulder surrounding each said inset face and normal thereto, said shoulders being complementary to said rim and said inset faces being complementary to said flat face, whereby when the flat face of said hub is seated against an inset face, the shoulder surrounding that inset face is seated on the rim of said flange.
Claim 6
Dependent Claim
109 words
A rotor for a caliper brake which comprises a first annular wear face and a second annular wear face, said annular wear faces having the same outside diameter but the first one having a smaller inside diameter than the second and apposed annular chamfers in said first annular wear face, having means therein whereby said rotor can be attached to a hub with the hub seated in one of said chamfers, said chamfers having a diameter less than that of the inside diameter of the second annular wear face, whereby the second annular wear face can pass over the hub to which the first annular wear face is attached.
Claim 7
Dependent Claim
109 words
A rotor for a caliper brake which comprises a first annular wear face and a second annular wear face, said annular wear faces having the same outside diameter but the first one having a smaller inside diameter than the second and apposed annular chamfers in said first annular wear face, having means therein whereby said rotor can be attached to a hub with the hub seated in one of said chamfers, said chamfers having a diameter less than that of the inside diameter of the second annular wear face, whereby the second annular wear face can pass over the hub to which the first annular wear face is attached.
Claim 8
Dependent Claim
33 words
The rotor of claim 5, in which said chamfers comprise apposed inset flat faces normal to the axis of said rotor and a shoulder surrounding each said inset flat face and normal thereto.
