DOOR-LOCK.

Specification of Letters Patent.

Patented Dec.4l:,191'7.

Application filed June 10, 1914. Serial No. 844,339.

To all whom it may concern:

Be it known that we, CLIFFORD TKAUT, a citizen of the United States, and a resident of Newportfln thefcounty of Campbell and State of Kentucky, and VVILLIAM B. Conn- MAN, a citizen of the United States, and a resident of Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Door-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

In the construction of doors for cells .in asylums for the insane and such like, it is required to have a door which is safe against springing open when locked. Such doors, although of open metallic framework, must be stiff and strong, and even then a pressure on the top edge of the door is liable to cause enough springing of the metal parts of the door to seriously damage the door or even to allow the locking bolt to slip out of its socket. F or this reason, it is found necessary to provide jump bars which when op erated serve to secure the whole side of the door to a series of studs in the door j amb.

In the door to be hereinafter specifically pointed out, and its novelty claimed, all of the above requirements are provided for, and in addition there is provision whereby the door cannot be locked without first shifting the jump bar into holding position, and the jump bar cannot be moved out of such position without first unlocking the door.

In the drawings,

Figure l is a front elevation of the door closed and taken from the outside, partly in section.

Fig. 2 is a horizontal section through the door looking toward the stop stud on the jump bar.

Fig. 3 is the jump bar, in perspective.

Fig. 4 is the angle plate on which the jump bar is mounted, also in perspective.

Fig. 5 is a vertical sectional view of the door closed against the angle plate on the jamb of the door, partly in elevation, and with the section taken outside of the line of the jump bar studs.

Figs. 6 and 7 are details in perspective of the corner portions in the side and bottom channel bars respectively of the framework of the door.

The framework of the door is composed of four channel bars 1, 1, for top and bottom,

and 2,- 2, for the sides of the door, with suitable lattice work for the body of the door. To strengthen the door, we provide for a strong and'durable means of connectbent up for the bottom, and down for the top bar, at 3. The base of the side bars is cut away at 4, so as to allow the flanges 55, .5, to abut against the ends of the flanges of the adjacent channel bar, and the tongues are then riveted at 6 to the base of the adj acent bars of the inside of the channels thereof.

Fitted into the open side of the channel bars and preferably bolted in place are the finishing plates 7. Angle plates 8 are set into the jamlos, and at the hinged side of the door the hinges 9, 9, are secured to the plates 8 and to the plates 7, some of the bolts 10 for securing the finishing plates serving also to hold the outer hinge leaf.

Mounted on the channel bar and its finishing plate at the front edge of the door is an L-bar or angle plate 11, the length of the door. Along the flange of this angle plate are a series of slots 12 for slidably mounting thereon the jump bar 13. Rivets 14 are used, preferably, for this purpose (Fig. 5), which pass through the holes 15 in the jump bars and the slots 12 above mentioned and slide in the slots.

It will be understood that this jump bar is mounted onthe outside of the angle plate. In this jump bar are slots 16, having large eyes 17 at the lower end; and it located so as to register with the eyes 17, when the jump bar is in raised position, are apertures 18 in the angle plates. Studs 19 having enlarged heads 20, are mounted in the door jambs, preferably so as to be held by the plates 8 thereon, and extend out wardly so as to pass through the apertures 18 and the eyes 17 of the slots in the jump bar. When the door is closed and the jump bar is in raised position on the angle plate, the heads of the studs will naturally pass through the plate and bar. A handle 21 on the jump bar may then be used to push it down on its slidable mounting so that the slots 16 will engage the shank of the studs and hold the heads 20 thereof in locked position. Thejump bar will thus hold the door fast closed at all places where it is desired to locate studs so as to prevent the bending of the door at any point to spring out or damage the locking bolt. It will be understood, of course, that the studs and slots can be arranged so that instead of pulling down the jump bar to lock it the movement can be in the opposite direction.

The lock is mounted in a casing 22 riveted preferably to a frame comprising a cross bar 23 secured to the two upright channel bars 2, and an angle 24esecured to the cross bar and the upright channel bar. There is only the bolt 25 of this look shown, as any desired construction ,of locks can be employed. The bolt 25 passes through the channel bar 2, the finishing plate 7 and the angle plate 11. Located in the jump bar, and extending through a long slot 26 in the flange portion of the angle plate is a block 27 This block is positioned so that when the jump bar is in raised position permitting the heads 20 of the studs 19 on the jamb to pass through the eyes 17 on the bar, then the block 27 will extend directly across the path of the bolt 25. When the jump bar is pushed down, however, to lock the heads 20 to the door, then the block is out of the way of the bolt which may be shot into place for locking. Once the bolt is shot, however, it

stands in the path of the jump bar block,v

making it impossible to raise the bar so as to release the heads 20.

We not only, therefore, provide an exceptionally stout frame for the door, and aump bar of simple constructlon and easyoperation, in connection with such frame, but We also make the door foolproof, al-

ways requiring a complete locking of the door and preventing a release of the ump tending beyond the front edge thereof,

headed studs on the frame, apertures in the angle plate to receive said studs, and a bar slidably mounted on the angle plate and having slots with wide portions to receive the heads of the bolts, and narrow I portions to engage under the heads, a locking bolt extending behind the angle plate,

a lug on the bar to be engaged by the bolt,

and a slotted aperture in the angle plate for the lug.
