Abstract

3062. Fothergill, J. Feb. 25. [Addition to 6967/12]. Lift doors, locking and unlocking.-The latch of the fastening for lift gates, as described in the parent Specification, is mechanically connected through a link x with the contact t'. By this arrangement, until the latch is in locking engagement with the catch c on the closed gate d, the contact t' does not engage with the contacts t<2>, p, and the flow of current through the controlling-circuit is interrupted. The fastening-members are locked in the engaged position by a cam on the spindle a, which extends in the path of the extension h of the latch. When the lift reaches a doorway, a projection on the lift cage engages a cam n and rotates the spindle a, so that the gate can then be opened.
