Abstract

724,054. Tyre-buffing machines. CHANNEL ISLANDS TYRE CO., Ltd., and KENT, J. H. F. Nov. 19, 1953 [Nov. 21, 1952], No. 29538/52. Class 31 (1). A tyre-buffing machine comprises a buffing disc 1 having teeth 3 and rotatable in a plane or planes which is or are substantially tangential to the tyre tread at the point of contact, means being provided to maintain the tyre in a position such that its central plane is offset with respect to the axis of rotation of the buffing disc whereby the teeth, in addition to their cutting action on the tread, impart a rotational thrust to the tyre causing it to revolve. In the form shown, the machine comprises a base frame 10 having hingedly attached thereto pairs of lever arms 18 having inturned ends 19 to receive inverted V-shaped support members 20 which are interconnected by means of links 9 so as to move in unison. The members 20 are provided with rollers 21 to engage the side walls of the tyre, and are movable to the closing position by means of a handle 22 which may be assisted by a spring 31. The buffing disc is rotated by means of a motor M and is mounted in a housing 13 provided with a fan 30 to assist in the collection of particles removed from the tyre, the bottom of the housing leading to a discharge shoot 28. In modifications, Figs. 8 and 9 (not shown), the buffing disc is formed with a concave, or conical, surface.
