Extract from Specification.—The invention consists in pivoting a small jib crane to a fixed stanchion or other support, and providing upon the shaft of the rope-winck a brake-drum, to which a brake is applied by the tension of the tie or flexible connection supporting the outer extremity of the jib. The support may be fixed—e.g., inside the window or opening—so that the crane can be revolved round the stanchion to be completely inside and behind shutters or curtains, or can be revolved so that the jib is outside and clear of the wall.
