11,844. Lucas, J. E. June 1. Lifts.-The cage B of a lift, hoist, &c. is suspended from a drum C connected with a second drum E from which a rope D passes to a drum F at the bottom of the well. On the same shaft as the drum F is a second drum G from which a rope H passes around guide sheaves to the counterweight L. The ropes are attached to the drums on which they are wound. The cage is raised or lowered by pulling either of the ropes D, H in the required direction. In a modified form, the drums E, F are connected by a second rope, which winds up on the drums as the first rope unwinds. For heavy loads spur or worm gearing is used for driving the drums.
