Abstract
535,637. Pulleys. BRAMMER, H. Dec. 27, 1939, No. 32878. [Class 80 (i)] A grooved belt-pulley comprises a pair of disc plates 2, 3 adapted to form deflected rim portions to provide a single belt groove 4 when the plates are fitted to a hub 5, a flange 11 on one or both of the plates forming one part of a friction or other clutch. The plates may be held against a shoulder 6 by lock nuts 7. The flange may be integral with the plate or welded thereto and may extend inwardly or outwardly. One plate may have a hub portion in the form of a screw-threaded sleeve over which the other plate may be screwed and locked in different positions by a nut to provide grooves 4 of different widths. Instead of the plates abutting at two plane surfaces 8, 9 they may be conical throughout, in which case the shoulder 6 and nut 7 have corresponding coned surfaces. A plug 12 may be inserted in the bore 13 to form part of the clutch-operating mechanism in a sewing machine. A number of pairs of plates to form a multi-groove pulley may be mounted on the hub which may be of metal or a phenolic formaldehyde substance.
