ABSTRACT:
An auxiliary lock is disclosed which is intended to be used as a night lock in combination with the hinge of a conventional door. The device includes an elongated cross bar and a plurality of adjustable stop members which project from and are threadedly received in said cross bar and are adapted to engage the surface of the door and the door jamb or wall. The cross bar also carries a spring-loaded connecting means which is adapted to be engaged with the hinge pin of a conventional door hinge to thereby hold the cross bar in place on the hinge and the stop members in engagement with the door and door jamb. The bar is pivotally connected to the hinge pin by the connecting means so that it may be rotated 90.degree. to permit normal operation of the door, and in this regard secondary stop members are provided to function as normal door stop members when the device is in its inoperative or unlocked position. The spring-loaded connecting means also includes a threaded handle which permits lessening of the spring tension to permit partial opening of the door without removal of the lock.
