Abstract
738,734. Combined clutch-brake. MARINE ENGINEERING CO. (STOCKPORT), Ltd. March 31, 1952 [March 30, 1951], No. 7367/51. Class 80 (2).. [Also in Group XXXV] In an electric motor, clutch and brake driving system for sewing machines &c. the driving pulley is axially slidable on the motor shaft f and carries a plate k with friction surfaces k<SP>2</SP> and k<SP>3</SP> which may engage a clutch surface on the motor flywheel g or a braking surface e carried by an arm c on which the actuating lever o is mounted. In the form shown, the pulley is biased into engagement with the braking surface by a spring h and is displaced towards the motor by the actuating lever to engage the clutch, but in a modification the pulley is biased to engage a conical clutch surface attached to the flywheel and operation of the lever causes it to engage the brake. Specification 606,574 is referred to.
