Abstract
Abstract Exemplification consists of a caliper brake end plate which also serves to mount the brake from a motor shell or the like. To hold the plate securely on motors having mounting bolts which are on bolt circles of differing radii, the plate is correspondingly arcuate about predetermined centers offset from the plate axis according to a formula.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
A universal mounting plate for attaching a driven device to the mounting bolts of a motor shell regardless of variation of the radius of the mounting bolt circle within a predetermined range, said plate being provided at predetermined angular spacing with slots of corresponding dimensions, said dimensions including a width which is substantially equal to the diameter of the respective bolts, each of said slots having corresponding arcuate curvature around corresponding points similarly offset from the center of said disc, the slots having sufficient arcuate extent so that their respective ends intersect bolt circles at the extreme of said range, and being so disposed as to fit snugly upon bolts at equal angular spacing in the respective circles.
Claim 2
Dependent Claim
118 words
A universal mounting plate for attaching a driven device to the mounting bolts of a motor shell regardless of variation of the radius of the mounting bolt circle within a predetermined range, said plate being provided at predetermined angular spacing with slots of corresponding dimensions, said dimensions including a width which is substantially equal to the diameter of the respective bolts, each of said slots having corresponding arcuate curvature around corresponding points similarly offset from the center of said disc, the slots having sufficient arcuate extent so that their respective ends intersect bolt circles at the extreme of said range, and being so disposed as to fit snugly upon bolts at equal angular spacing in the respective circles.
Claim 3
Dependent Claim
175 words
A universal mounting plate for attaching a driven device to the mounting bolts of a motor shell regardless of variation of the radius of the mounting bolt circle within a predetermined range, said plate comprising the fixed disc of a caliper brake which constitutes the said driven device to be attached to the motor shell and is adapted to act on the armature shaft with which the motor shell is provided, said plate having centrally an opening for said armature shaft and having slots at predetermined angular spacing and in proximity to the outer perimeter of said plate, said slots being of corresponding dimensions including a width which is substantially equal to the diameter of the respective bolts, each of said slots having corresponding arcuate curvature around corresponding points similarly offset from the center of said disc, the slots having sufficient arcuate extent so that their respective ends intersect bolt circles at the extreme of said range, and being so disposed as to fit snugly upon bolts at equal angular spacing in the respective circles.
Claim 4
Dependent Claim
