Abstract
5216. Goodare, J., and Goodare, J. B. March 6. Locks, key.-In night-latches and other door locks, a spring - controlled trigger bolt is employed to retain the locking-bolt in the retracted position, when the door is opened, the trigger bolt being actuated to release the locking-bolt when the door is closed. Figs. 1 and 5 show the application of the invention to a night-latch, in which both lifters or latches and a sliding bolt are employed. The pivoted trigger bolt A is provided with a projection a', which is forced into engagement with a recess c' in the locking-bolt C when the bolt is withdrawn and the door opened. The bolt C is retracted by lifting a lifter or lever H, which is connected to a pivoted lever E adapted to engage a lever F coupled to the bolt C. Upon closing the door, the cylindrical nose a<2> of the bolt A engages a projection on the striking-plate K, and the projection a<1> is disengaged from the recess c', thereby allowing the bolt C to be shot. By this arrangement, the key or knob only require half a turn to withdraw the bolt. Owing to the cylindrical form of the nose a<2>, the lock is reversible. The invention is also described as applied to an ordinary night-latch &c., the locking- bolt being formed with a rectangular end.
