Abstract
180,810. Blackham, H. March 24, 1921. Centrifugal machines ; moulding grinding wheels.-Blow-holes in grinding-wheels are avoided by rotating the material in a mould so as to consolidate it by centrifugal force from the periphery inwards, and air present being forced tcwards the centre, which is subsequently removed during drilling. The mould comprises a ring g having covers h of canvas, thin metal, &c., and is clamped to the rotating table a by means of a cover e secured by pivoted screws c and binding nuts c<1>. Alternatively, the cover e may be hinged to one or more of the screws c. The mould g is centred by dogs m, Fig. 3, adjustable in radial arms k.
