EMERGENCY EXIT-DOOR LOCK- Specification of Letters Patent.
Patented Nov. 21, 1905.
Application filed February 27, 1904. Serial No. 195,671.
- T aZZ whom it may concern.-
Be it known that I, HUGHELMER CLARK, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a new and useful Emergency Exit-Door Look, of which the following is a specification.
My invention relates to improvements in emergency exit-door looks.
The objects of my improvement are, first, a lock which may be instantaneously released, consciously or unconsciously, by a person or number of persons pushing a horizontal lever on an exitdopr; second, to obviate the use of a key third, a lock having bolts which are all operated by a horizontal lever, said lever having a length in the width of the door.
In the drawings, Figure 1 is a perspective View of a door embodying this invention, and Fig. 2 is an elevation of a plate forming part of the lock thereof.
The door X, forming an exit from a room, such as an amusement-hall or theater, is hinged to its casing in anysuitable ordinary way. Upon the door next to its hinged side is fastened a support or pedestal M, to which is hinged or pivoted, as by the bolt or pin N, the other hinged part 0, which is connected with a plate P in any suitable manner, such as by the rod or tube Q. Inasmuch as the pin or bolt N is vertical the plate P can move horizontally to and from the door. From the opposite end of the plate from the hinge above mentioned extends the pin or rod K, which is guided in a stationary supportingpiece Y, Fig. 2. The plate Y has a horizontal slot J in which the pin K moves and at its outward extremity a depressed socket R in which the said pin may rest, so that a slight eflort is needed in order to raise the pin vertically from the socket R into the horizontal slot J. To the door is fastened a plate I, which may carry the plate Y above mentioned and also lugs E, by which operatinglevers H H are pivoted to the door. Each lever at one end has a slot L, through which the pin K passes and whereby on movement of the plate P to and from the door the said operating-levers are tilted. On the opposite sides of the fulcrums of the levers from the slots L there are pivoted to the arms G thereof the locking rods C C conveniently by means of the yokes F F. The locking-rods run through guides B and D upon the door and engage socket-plates A A, which may be in the top and bottom of the door-casing or at any other suitable point.
Normally the parts are at rest in the position shown in Fig. 1 in which the pin K lies in its socket R and in the outer ends of the slots L in the operating-levers H. In this position the bolts C C engage in the sockets A A and lock the door in closed position. Upon sufiicient pressure on the plate P the pin K is forced out of its recess or socket R and through the length of the horizontal slot J tilting the operating-levers H H inward and retracting the bolts C, unlocking the door, and permitting it to be swung open in the same direction as the pressure upon the plate P.
Of course only one operating-lever H and locking-rod C and socket-plate A need be employed upon a single door.
What I claim is 1. In an automatic door-lock, a door, a plate hinged to the door and adapted to move horizontally to and from the same and having a projecting pin, a guide-plate for said pin having a horizontal slot with a socket at the outer end of said slot for retaining said pin in position, an operating-lever having a slot spanning said pin, a bolt on said door adapted to be operated by said lever, and a socket on the door-casing adapted to be engaged by said bolt.
2. In an automatic door-lock, a door, a plate hinged to the door and adapted to move horizontally to and from the same and having a projecting pin, a guide-plate for said pin having a horizontal slot with a socket at the outer end of said slot for retaining said pin in position, an operating-lever having a slot in one arm spanning said pin, a bolt on said door connected to the other arm of said lever, and a socket on the door-casing adapted to be engaged by said bolt.
In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
HUGH ELMER CLARK.
