Abstract

774,787. Explosion proof winch blocks. STAHL, A., STAHL, O., and STAHL, O., [trading as STAHL MASCHINENFABRIK, R.]. Nov. 13, 1952 [April 23, 1952], No. 28630/52. Class 78 (5). [Also in Group XXXV] An explosion-proof winch block has its motor 50 enclosed in a pressure-proof housing 100 which is positioned inside the winch drum 1. As shown, the housing 100 includes component members 2, 3, 4, 5 and encloses the motor 50 and sliding brake disc 11, the passages for electric leads 8 and for sliding shaft 6 being pressureproofed.
