Реферат: 28,740. Lovelace, E. J., and Phoenix Art Metal Engineering Co. Dec. 31. Lifts.-An automatic locking - device for lift gates consists of catches carried by an unequally weighted lever, which is mounted near the well opening, and is engaged by the cage so as to release the gate on arrival at a floor, and retain the door in the open position until the cage leaves the floor, the door being closed by a balance weight. The lever F is balanced as shown, so that the catch E lies in the path of an extended picket G of the gate, t h u s locking it. When the cage arrives, a striker J engages a roller K and releases the door, which, after being opened, is held by a catch N. When the cage leaves, the weight B closes the gate.
