Abstract

789,724. Tyre levers. DUNLOP RUBBER CO., Ltd. April 15, 1955 [April 21, 1954], No. 11432/54. Class 144 (1). A tyre-removing tool comprises a lever 1 having at one end a cranked portion terminating in a flattened shoe which engages between a tyre bead and its retaining flange and has a heel portion to fulcrum against the rim flange and a lip 5 projecting from its toe portion to lock behind the bead so that when the lever is rocked tangentially of the rim, the shoe pivots about its heel portion and its toe portion separates the bead from its rim seat. The tool is used to effect complete separation after initial separation has been effected by such tools as those described in Specifications 694,973 and 789,723. As shown, the shoe 3 is formed at the end of one limb of a forged steel U-shaped member 2 which is pinned to one end of the lever 1, the other end of the lever having a crowbar tip 6 for use as required in effecting initial separation of the tyre bead and rim flange.
