Abstract
678,832. Variable-speed gearing. CAMCO (MACHINERY), Ltd. April 17, 1951 [April 17, 1950], No. 9393/50. Class 80 (ii), An expanding conical pulley has the conical flanges 15, 25, of a light weight metal, such as aluminium, and the associated sleeve portions 10, 17, of high duty metal, such as high grade steel. As shown, the sleeve parts 10, 17, are slidably keyed together by a key 20. The flanges 15, 25, are screwed to the sleeves and locked thereon by screws 16, 28, which pass axially through the screw threads between the sleeves and flanges. Solid pegs may replace the screws 16, 28. The flanges 15, 25, are urged towards one another by a spring 33 which abuts an adjustable collar 32 on the sleeve 10 and a collar 22 on the sleeve 17. When changing the gear ratio the distance between the pulley and a cooperating pulley is varied. The pulley is for use in small electric driven machines, such as paper folding and paper handling machinery, and eliminates the harmful effect of centrifugal force set up in the pulley flanges in operation.
