GB276588A - Improvements in friction clutches of the single or multiple disc or plate type - Google Patents

Abstract

276,588. Shepherd, L. W. April 5, 1927. Clutches, friction, of the single or multiple plate type. Pins E affixed in the pressure plate C are adapted to be engaged by adjustable screw studs F on levers G rocked by the movement of the operating sleeve H, springs E<1> under the heads of the pressure pins E being compressed on putting the clutch into action and acting to relieve the pressure between the clutch surfaces immediately the sleeve is moved away therefrom. The links g<1> connecting the levers G to the sleeve are preferably arranged as nearly as possible at right angles to the shah to obviate automatic clutching under the action of centrifugal force. As shown, the clutch comprises a friction disc B of fibre, wood or similar material, slidable on keys a on the hub or inside periphery of a shell A, co-operating with the pressure plate C slidable on keys d on the boss of the driving member D, the pins E passing through holes in the driving member. A ring K or a number of segmental flanges secured to the shell A surrounds and is normally clear of the driving member D but engages therewith when the clutch is put into engagement to take up end pressure and prevent the transmission thereof to collars on the shaft.
