Abstract

819,512. Pneumatic winches. MAIRE, C. A. March 26, 1957 [April 27, 1956; Dec. 3, 1956], No. 9911/57. Class 78 (5). Air motor 1 drives winch drum 9 through shaft 2, sun pinion 3, planet gears 4 co-operating with fixed gear ring 6 and transmitting the drive through gear ring 7 to gear 8, gears 10 and internal gear 11, the latter being formed on the winch drum. The motor is started by the operator depressing lever which depression admits compressed air through passages 33, 34 to cause separation of pistons 31, 32 to release brake blocks 22, 23 from the brake drum, and then admits air to the motor to drive it.
