Apparatus for mounting a wheel on a balancer
First Claim
1. An apparatus for mounting a wheel on a spindle having a circular backing plate coaxially attached thereto, said backing plate having a planar reference surface that is perpendicular to said axis, said wheel having a plurality of mounting holes therethrough with the centers of the mounting holes located on a mounting hole circle and symmetrically disposed around a central hole through said wheel, said mounting hole circle and said central hole having centers that are located on the axis of rotation of said wheel, said apparatus comprising:
- a disk member having first and second planar surfaces, said first planar surface having a first plurality of circular recesses therein with the centers of said recesses located on a mounting circle haing the same diameter as the mounting hole circle of said wheel and being symmetrically disposed around a central bore through said disk member in a manner identical to the manner in which the mounting holes of said wheel are disposed around the central hole through said wheel, said central bore being coaxial with said disk member and said circle having a center that is located on said axis, said central bore having a diameter such that said spindle may be inserted therethrough;
a mounting pin resiliently disposed in each of said recesses, the axes of said mounting pins being parallel to the axis of said disk member and central bore, an inwardly tapered portion of each mounting pin extending outwardly from said first planar surface to engage a mounting hole of said wheel when said spindle is inserted through said central bore such that said second planar surface engages the reference surface of said backing plate and a means for securing retains said wheel against said first planar surface.

Abstract
An apparatus for accurately centering a wheel on the spindle of a balancer is disclosed. The apparatus has mounting pins resiliently disposed in recesses in the surface of a disk member. The mounting pins have locations that correspond to the mounting holes in a wheel, and engage the mounting holes in the wheel when a means for securing retains the wheel against a planar surface of the disk member.

6. An assembly for balancing a wheel of the type having a plurality of mounting holes therethrough with the centers of the mounting holes located on a mounting hole circle and symmetrically disposed around a central hole through said wheel, said mounting hole circle and said central hole having centers that are located on the axis of rotation of said wheel, said assembly comprising:
-
(a) a wheel balancer comprising a means for rotating a spindle and a spindle having a circular backing plate coaxially attached thereto, one end of said spindle being attached to said means for rotating and another end of said spindle being unsupported, said backing plate having a planar reference surface that is perpendicular to said axis and faces the unsupported end of said spindle; (b) an apparatus for mounting said wheel on said spindle comprising (i) a disk member having first and second planar surfaces, said first planar surface having a first plurality of circular recesses therein with the centers of said recesses located on a mounting circle having the same diameter as the mounting hole circle of said wheel and being symmetrically disposed around a central bore through said disk member in a manner identical to the manner in which the mounting holes of said wheel are disposed around the central hole through said wheel, the spindle of said wheel balancer being inserted through said central bore and said second planar surface engaging the reference surface of said backing plate, said disk member being coaxial with said spindle and backing plate, and (ii) a mounting pin resiliently disposed in each of said recesses, the axes of said mounting pins being parallel to the axis of said disk member, an inwardly tapered portion of each mounting pin extending outwardly from the first planar surface of said disk member to engage a mounting hole of said wheel; and (c) a means for securing attached by means for attachment to said spindle to retain said wheel against the first planar surface of said disk member. - View Dependent Claims (7, 8, 9, 10)
