UNITED. STATES PATENT OFFICE.
DOOR FASTENING.
Application filed October 27, 1924. Serial No. 746,183.
To all whom it may concern:
Be it known that I, LAUCHLAN ALEXAN- DER MAGKAY MoGnooH, a subject of ,the King of Great Britain and Northern Ireland, and residing at Glasgow, Scotland, have invented a certain new and useful Improvement in Door Fastenings, 01": which the following is a specification.
This invention relates to locks for the doors of ships cabins of the class provided with an ajar hook arranged as a component part of the mortice lock and cooperating with a socket disposed adjacent to the lock striking plate, the arrangement being such that when in operative position, the ajar hook is capable of being locked against movement, and, when the ajar hook is in inoperative position, the body' 01' the hookis accommodated within the mortise look so as to clear the striking plate.
Locks of this class usually include a mortise case equipped with a latch bolt operable by a knob in opposition to a spring and associated with a secondary bolt adapted to hold the latch boltin locked position and controlled from the outside of the door by a key and from the inside of the door by a knob, there being fitted within the case for sliding and circular movements a springurged plunger formed with a locking barrel for cooperation with the secondary bolt and with a tie bar which constitutes the ajar hook pro-per, and which is formed with a knob 'engageable with a key-hole slot in a retaining plate located adjacent to or formed integral with the striking plate.
According to the invention there are employed for controlling the sliding movements of the secondary bolt a system of levers adapted for cooperation with a key inserted in the look from the outside and a supplementary bolt having a pin entering slots in the levers and having an elongated notch engageable by one arm of a bellcrank lover of which the other arm is connected to the secondary bolt, and a knob located on the inside of the door and operatively connected to the bell crank lever.
In the barrel are formed perforations which are spaced circularly and axially from one another and are engageable with an eX- tension rod on the secondary'bolt, the ar rangement beingsuch that, when the secondary bolt is shot, the plunger may be rethe usual way so long as the secondary bolt i is unshot and the other rollback being formed with two arms of which one engages a projection on the latch bolt and the other is arranged inoperative relationship with a shoulder on the secondary bolt, so that, in the event of the secondary bolt being shot, rotary movement imparted to the saidrollback by the knob located on the inside of the door is accompaniedby movement of the secondary bolt 'into inoperative" position followed by withdrawal of the latch bolt.
In the accompanying drawings F 1 is.
an elevation of the lock of the invention as 'Viewedfrom the inner side of a door; Fig.
2v is an end elevation; Figs. 8,4 and 5 are views of the interior of the lock.
The lock shown is provided with an ajar hook 1 arranged as a' component part of the mortice lock and co-operating with a key-hole socket 2 disposed adjacent to the lock striking plate 3. As heretofore, provision is made for locking the ajar hook 1 against movement by the operation of the usual locking means controlling the latch bolt 5 of the inortice lock. When the ajar hook is in inoperative position, the body of the book 1 is accommodated within the 1nortice look so as to clear the striking plate 3. The mortice lock includes a mortice case 6 wherein is fitted the latch bolt 5 operable from the exterior of the cabin by a knob 7 in opposition to a spring 8 and associated with a secondary bolt 9 adapted to holdthe latch bolt 5 in locked position. The bolt 9 is controlled from the outside of the cabin by a key 10 and from the inside of the door by a finger knob 11. Fitted within the mortice case 6 so as to be capable of performing sliding and circular movements relatively to the caseis a spring-urged plunger 12 formed on the inner end with a locking barrel 13 adapted for cooperation with the secondary bolt 9 and on the outer end with a tie bar which constitutes the ajar hook proper and said levers and having an elongated notch, a manually operable bell-crank lever having one arm engageable with said notch and having the other arm connected to said secondary bolt, and two rollbaoks for operating said latch bolt, one of said rollbacks adapted to operate said latch bolt so long as said secondary bolt is unshot, and the other rollback being formed With an arm engageable with said projection and an arm engageable 10 with said shoulder.
In testimony whereof I have signed my name to this specification.
