ABSTRACT:
A deadbolt-type doorlock particularly useful for public buildings such as schools which enables the locked or unlocked condition of the lock to be visually displayed and also enables locking of the slide bolt in either its door locking or door unlocking position. The deadbolt lock includes a lock housing having a movable bolt assembly therein. A blade is fastened to the bolt and forms a hole which aligns with one of two bores through the lock housing when the bolt is in the door locking and door unlocking positions. A conventional padlock assembly of the type having a separate locking loop is used which passes through both of the lock housing bores. Indicia on the padlock assembly lock housing can be provided on its two major face surfaces to designate the state of the lock.
