Abstract

241,242. British Hele-Shaw Patent Clutch Co., Ltd., and Wallace, W. April 17, 1924. Clutches, friction. - In centrifugal friction clutches used to facilitate the starting of electromotors or other machinery, a radially-moving driving member and a driven drum are formed with corresponding ridges and grooves to increase the grip, and means may be provided for varying the quantity of lubricant in the clutch to determine the speed at which slip shall cease. The clutching parts may be of cast iron, wood, brass, copper, phosphor-bronze, antifriction metal, asbestos or other fibre, or brake-lining fabric. The driving-shaft 31 carries radiallyguided blocks 22 coacting with a drum 11 having an oiltight cover 14 and secured on the driven shaft 36 or formed as a pulley. The engaging- surfaces of the clutch are provided with cooperating ridges 13, 23 and grooves 12, 24 with inclined, stepped, or curved sides. The grooves terminate in deeper U-shaped recesses to facilitate manufacture and the correct engagement of the parts when worn, and these recesses may be deep enough, or may communicate with other cavities, to allow lubricant, for example oil, soap solution, or a mixture of these, to drain centrifugally from the surfaces. Two or other number of plugged passages 25, communicating with the grooves, allow varying quantities of lubricant to be supplied according to the speed at which slip is to cease. The quality of lubricant may also be varied. Light compression springs 29 may be provided for preventing the blocks 22 from falling inwards, or adjustable tension springs may be used to determine the speed of engagement. Specifications 10637/10, 3682/11, and 224,711 are referred to.
