LOCKING MEANS FOR DOORS.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed August 28, 1914. Serial No. 859,015.

To all whom it may concern:

Be it known that I, JAMES SHIREY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Lock ing Means for Doors, of which the following is a specification.

My invention relates to improvements in locking-means for doors, and my object is in general to provide a simple, strong and durable locking-mechanism capable of application to all common forms of doors.

Further objects and advantages of my invention will appear'from the following detailed description of the same, in which, for purposes of illustration, I will particularly describe an embodiment of the invention as applied to a well-known type ofdouble-door.

In the description, reference will be made to the accompanying drawings, in which Figure 1 is a front elevation of a double door and frame for the same, showing the locked and unlocked positions; Fig. 2 is a detailed perspective view of the slide-rod and the connection with the lockin -bar; Fig. 3 is an enlarged sectional view of the end of the locking-bar and the socket of the doorframe in which it engages; Fig. 4: is a section on line 4 of Fig. 3; Fig. 5 is an enlarged front elevation of the locking-platewhich is secured to the door, the key of the lockingbar being shown in section; Fig. 6 is a section on line 6 of Fig. 5, showing also the locking-bar and key; Fig. 7 is a rear face view of the locking-plate; Fig. 8 is a section on the line 8 of Fig. 6, and Fig. 9 is a detail section on the line 9 of Fig. 1. a

In the drawings, 10 indicates the doorframe in which is mounted a pair of swinging-

doors

11, 12. These doors may be of either of the one-way or two-way type, the locking-means being adapted for both constructions, as will later appear. To apply my lock to such a door and frame, I mount upon the inner face of one of the vertical frame-members a slide-bar 13 which is spaced away from the door-frame, as by the angular feet 14. Mounted to slide on the bar'13 is a sleeve 15 which has formed thereon the tongue 16 to which is pivoted, as by a pin or rivet 17 ,the slotted-end plug 18. The outer end of the plug is reduced as at 19 to fit within the bore of a ingly flared surfaces tubular locking-bar 20, i

a bolt or other fastening means, indicated at 21, being employed to hold the plug within the bore of the tube. Intermediate the length of the locking-bar it is encircled by split sleeves 22 carrying key-members 23 which are adapted to engage within the key-holesha'ped apertures of locking-plates 24. The split sleeves 22 are clamped in proper position upon the locking-bar by cap-screws 25.

Referring to Figs. 5 to 8, it will be seen that the locking-plates 24 are let into the face ofthe door, as indicated at 26, so as to lie flush with the same, and are secured in position, as by counter-sunk screws 27. Back of the plates the doors are cut away to form rectangular recesses 28 which accommodate the enlarged ends 29 of the keys. The apertures 30 of the locking-plates are of key-hole shape, as stated, so that the enlarged ends of the keys may be introduced into the upper enlargement of the apertures 30, and upon being moved downwardly are locked within the recess 28 by the side walls 31 of the lower narrowed ends of the apertures 30. As shown in Fig. 8, these sidewalls flare inwardly to engage correspond- 32 on the enlargements 29 of the keys. As a means of drawing the sleeves 22 tightly into engagement with the outer faces of the locking-plates, I form upon the inner faces of the locking-plates the inclined surfaces indicated at 33 in Fig. 6. These surfaces co-act with the enlarged heads 29 of the keys, to wedge the same tightly in place as the keys are forced clownwardly in the slots.

Referring to Figs. 3 and 4, it will be seen that the free end of the locking-bar is slotted at 33 to receive a hasp 3% which is threaded into the telescoping tube-section 35. A second hasp, shown at 36, is threaded into the wall of the locking-bar so as to lie adjacent to and in alinement with the hasp 34 when the telescoping-section 35 is in its extended position. To look the hasps in the position shown in Fig. 3, a padlock, conventionally illustrated at 37 may be employed. The telescoping-section 35 engages within a socket 38 let into the inner face of the vertical side-frame member of the door-frame. This socket, like the locking-plate, is preferably flush with the surface in order to present a neat appearance. A socket 39, similar to the socket 38, may be let into the under face of the top-frame member of the doorframe. 1

The operation of my locking-mechanism is as follows: When the parts are in the unlocked or inoperative position, as indicated.

in dotted lines in Fig. 1, the telescopingsection 35 will be engaged with the socket 39, (being so held by the padlock 37, not shown in this figure) the sleeve 15 will be at the bottom of the slide-bar 13, and in this position of the parts the doors will be entirely unobstructed and free to swing in either direction. When it is desired to lock the doors, .the padlock 37 will be removed and V .-;imately horizontal position opposite the locking-plates of the doors, the keys 23 being opposite the enlarged upper ends of the apertures in the locking-plates. The free end of the locking-bar which formerly stood at a slight angle to the doors will now be moved back toward the same, causing the keys 23 to pass through the apertures in the locking-plates, and when this has been effected, the free end of the bar will be swung --downwardly, thus causing the keys to move downwardly and become wedged within the lower slots of the locking-plates. If the parts have been accurately fitted, the end of the locking-bar will now stand opposite the socket 38, and the hasp 34 may be pushed forward to engage the telescoping-section 35 within the socket. The padlock 37 may then be snapped through the

hasps

34, 36. It will be seen that in this position of the parts the doors are positively held against all movement. If they are folding-doors, as described, they can not be swung in either direction, the keys 23 being wedged so tightly Within the apertures of the locking-plates as to even prevent rattling of the doors. As an additional means of preventing rattling of the doors, I may fasten to the faces of the same the wedge plates 40, shown in Figs. 1 and 9. These plates have inclined front faces which in the locked position of theparts bear against and tightly wedge the locking-bar 20. These plates 40 are not at all necessary to the action of the locking means, however, and need only be used where it is important to prevent the least rattling of the parts.

It will be readily understood that the form of locking-means which I have described as applied to a double swinging-door will serve without change for a single door of the swinging type or for a single or double door of the sliding type, the form of the locking arrangement being such that the door or doors are positively held against all movement. The same form of locking device may be applied in precisely the same way to revolving-doors, it being understood that the sections of revolving-doors are pivoted to one another so that they may be brought into a single plane when it is desired to lock the door. In such position of the parts, the door-sections would occupy the same relation to one another as do the. double folding-

y doors

11 and 12 in Fig. 1, and the locking bar'would be applied'in precisely the same way, excepting that it would be necessary, of course, to recess the door-frame or casing to receive the slide-bar 16 and also to receive the locking-bar when it is in the inoperative position. Y Y

In order to'adapt my locking mechanism for doors of different sizes, it is'only necessary to change the length of the locking-bar i and the slide-bar, andthis maybe done by any dealer in such apparatus. The locking? plates and all other fittings are identically the same for all classes and sizes of doors to which the locking-mechanism may be applied.

\Vhile I have shown and described in considerable detail a construction embodying my invention, it is to be understood that such description and showing is illustrative only, and that my invention is not to be construed as limited to the structural features or combinations of elements shown, except in so far as such limitation is included within the appended'claims.
