Abstract
The wheel rim to be crushed with the tire on it is placed horizontally upon a support and three pusher heads are moved radially inward against the tire by equalized hydraulic cylinders spaced equally about the circumference. A frame with three radially disposed beams supports the cylinders and a slide interlock between each pusher head and the corresponding beam retains the head in the plane of the wheel rim and tire.
Claims7
The method of crushing a vehicle wheel rim with a tire thereon comprising applying radial pressure upon at least three substantially equally circumferentially spaced locations against the tire to move the latter inwardly against the rim and collapse the rim, thereupon releasing the pressure and removing the tire from the collapsed rim.
Apparatus for crushing a vehicle wheel rim with the tire thereon, comprising a pusher head for applying radial pressure upon each of at least three substantially equally circumferentially spaced locations against the tire to move the latter inwardly against the rim and collapse the rim, hydraulic means for moving each said pusher head and comprising a power cylinder with a plunger operatively connected to each corresponding pusher head, means mounting each said cylinder upon a radially extending beam with the several beams rigidly secured centrally of the apparatus to constitute a frame therefor, and slide means supporting each pusher head upon the corresponding beam and interlocking the same against any tendency for said pusher head to raise from the beam.
The construction of claim 6 in which said last named means comprises an equalizing valve connecting said pump to said cylinders.
