A counterweight for an elevator is defined by a disc, which can be slidably mounted in tracks in an elevator shaft. Annular grooves in the periphery of the disc receive cables, which are anchored at the top of the shaft, and extend around pulleys on the rear of a car and a sheave driven by a reversible motor, whereby when the motor is actuated, the elevator moves vertically in one direction, while the counterweight rotates and moves vertically in the opposite direction.

Contrepoids d'ascenseur consistant en un disque monté de manière à glisser sur des rails dans une gaine d'ascenseur. Des gorges circulaires autour du disque reçoivent des câbles qui sont ancrés au sommet de la gaine, et de prolongent autour de poulie sur l'arrière d'une cabine, et un réa entraîné par un moteur réversible; lorsque le moteur est mis en marche, l'ascenseur se déplace verticalement dans une direction, alors que le contrepoids tourne et se déplace verticalement dans la direction opposée.
