Abstract
A portable, lightweight, tire bead breaking apparatus includes a vertically oriented frame disposed upon a wheeled base. A hydraulically actuated ram is pivotally mounted to the frame. A bead breaking shoe is attached to a distal end of the ram, and engages the beaded edge of a tire mounted upon a swivel pan rotatably mounted to the base. The bead breaking operator is able to simultaneously operate the ram, while rotating the tire disposed upon the swivel pan.
Claims18
A bead breaking machine, comprising:
- a base;
- a frame supported upon said base, said frame carrying an actuatable ram that is pivotally mounted for arcuate movement with respect to said frame via control arm means disposed therebetween, said actuatable ram for supplying a bead breaking force upon the bead of a tire in a direction downwardly and then away from a rim of a tire wheel supporting said tire by reason of said arcuate movement;
- a shoe mounted to said ram for engaging said tire when said ram is actuated, in order to force said tire away from said tire wheel;
- actuation means operatively attached to said ram for actuating said ram, and for causing said ram to push said shoe into engagement with said tire, causing said tire to separate from said tire wheel;
- and
- a rotatable support rotatively mounted to said base and supporting said tire for rotation about said base, whereby said tire can be rotated concurrently with actuation of said ram to break said bead by force directed circumferentially about said tire rim.

A bead breaking machine, comprising:
- a base;
- a rigid frame supported upon said base, said rigid frame carrying an actuatable ram for supplying a bead breaking force upon the bead of a tire, said ram directing said bead breaking force downwardly and inwardly towards a rim of said tire;
- a shoe pivotally mounted to said frame and connected to said ram for engaging said tire when said ram is actuated, in order to force said tire away from said rim;
- actuation means operatively attached to said ram for actuating said ram, and for causing said ram to push said shoe into engagement with said tire, causing said tire to separate from said tire rim;
- and
- a rotatable support rotatively mounted to said base and supporting said tire for rotation about said base, whereby said tire can be rotated concurrently with the actuation of said ram to break said bead by force directed thereupon.

- a shoe mounted to said ram for engaging said tire when said ram is actuated, in order to force said tire away from said tire rim;
- and
- actuation means supported by said frame and operatively attached to said ram for actuating said ram, and for causing said ram to push said shoe into engagement with said tire, causing said tire to separate from said tire rim.
