Abstract
271,776. La Rue, T. Feb. 1, 1927. Cage and platform lifts. -To prevent injury when a person or heavy body falls down the lift well, a buffer device is provided at the bottom of the well and is connected to an emergency power cut-off gear and to a signalling device. A platform 22 mounted on springs 24 is fitted in the sump 12 of the lift well and carries a mattress 26 surrounded by a flexible guard 28 supported from a frame 27. A flexible connection 32 is fixed to one side of the platform 22 and passes over a guide pulley 33 to the movable arm of a switch 16, Fig. 4, in the circuit of the hoisting motor M of the lift. A second flexible connection 35 connected to the other side of the platform passes over a pulley 37 to the movable arm of a switch 20 in a circuit 19 connected to the accumulator 14 or other source of power and including a signal device 21. The motor which is normally closed and the signal switch is normally open, but when the falling body strikes the platform, the motor switch is opened and the signal switch closes, so stopping the motor and giving the alarm.
