Abstract (en)
The positively-controlled fire curtain is for use in a theatre, and is suspended by two ropes (4, 5). A hydraulic ram (13) acts between the ropes and a fixed structure, so as to lift and lower the curtain (2). The ram can be mounted horizontally above the uppermost position of the curtain. The ram cylinder can be fixed to the supporting structure, while the piston rod end has a bracket with two freely-rotating pulleys, round which the ropes are reeved. On a horizontal line through the ram and above each rope there can be a further pulley, each freely rotating on the fixed structure.
