Abstract

574,670. Rotary filing - machines. DUNLOP RUBBER CO., Ltd., WILLSHAW, H., and GOODHALL, S. N. Sept. 28, 1944, No. 18575. [Class 83 (iii)] In a machine for removing the tread from a tyre by a rotary rasp prior to re-treading, the tyre is mounted on a freely rotatable rim or expanding chuck 5 carried by a cradle 2 suspended by trunnions 3 on a base 1. The rim 5 is mounted on a pin 9 on a slide 4 adjustable transversely to the axis C-C of the trunnions by a screw hand-operated at 7 through bevel gears 11, the inclination of the axis C-C being such that contact of the tyre with a rasp 6 rotated on a stationary horizontal axis by a motor causes the tyre to be rotated about its axis A-A during cutting. Simultaneously, the cradle 2 is swung about its trunnions by a hand wheel 8 and irreversible gearing 10 so that the rasp may operate on one half of the work periphery, after completion of which the work is reversed on its support 5 for operation on the other half. The slide 4 is adjusted so that the circle whose diameter is the mean diameter of the tyre and which lies in the central plane thereof is tangential to the axis C-C. The slide 4 is arranged as close to the floor as possible, to facilitate loading and unloading the work.
