.ample, water closets'such as are commonly used in railway cars, but which is also adapted to levers for various other uses.

rIhe object of .m-y.- invention is to provide means whereby an operating lever canreadily be made inoperative when for any reason it may be desirable to temporarily prevent rotation thereof, and the invention consists broadly in providing a locking device adapt- .edV to engage the lever and prevent rotation upon its pivot.

With the aforesaid and other objects in view the invention consists in the various novel detailsof construction and combination 4of parts hereinafter fully described in the specification, illustrated in the drawings and moreV particularly pointed out in the claims.A i l i In the accompanying drawings forming part of the specification, and in which like -reference numerals indicate corresponding parts, I have illustrated one form of mechanism' embodying the essential features :of my invention, although it is obvious that the same may be carried into effect in other ,ways` without inthe Aleast'departing from the spirit thereof. fi Y In the said drawings Figure l is a front .view showing the wall bracket and the operating lever with my improvement applied and the part-s locked together. Fig. 2 is a sectional view through the lines of Fig. l, the o] erating lever being :shown locked in inoperative position.. F ig.`3 is a top plan view of the bracket. Fig. 4 is a side view of the bracket. Fig. 5 is a sectional view through .the longitudinal center of the lock cylinder. Fig. 6 is a similar `viewto Fig. "5

with the boltand spring removed. Fig. 7 is a perspective partial sectional view of the locking bolt. Fig. 8 is a cross section of the operating lever taken on the line A A of Fig. l and shows the stop lug `and a portion of .the web, and Fig. 9 isa side View of the key for loperating the locking bolt.

Referring `to the said drawings l represents an operating lever pivotally mounted at 2 on a bracket 3 which is adapted to be secured to the wall of a railway car or other support. To one side of the bracket 3 I provide a member 4, which may be formed integral with or separate from the bracket as may be deemed advisable, in the present `instance it is formed integral with the bracket from which it is partially separated by a web 5. The member l is provided with a bore 6 having circumferential grooves or channels 7, 8 communicating with each other through a longitudinal groove'or channel 9. lVithin the bore G'there is located a bolt 10 capable ,of rotative and longitudinal movementand provided witlra projecting lug 1l adapted to traverse .the channels 7,V 8 and 9.

The bolt 10 has central bore IQeXtending from its rear end a suitable distance forward to receive a spiral spring 13 one end of which bears against the ybottom la of the larger bore 6 while the other end finds its bearing against the bottom of the bore l2, and thus the spring exerts constant out- Ward pressureon the bolt which when in its outward position engages a perforation l5 formed in the operating lever l and whenA these parts are sov engaged rotation of the said lever is prevented and cannot be accomplished until the bolt is withdrawn.

It is to be observed, however, that as a matter of expediency in manufacture, instead of the channels y7, 8 extending' completely around the wall they may extend only a sufficient distance therearound to permit of a quarter or half turn ofthe bolt;

and that in the former case stopsmav be provided in the channels so that the 1'bolt can only be given a quarter or half turn as may be deemed advisable. Normally the forward end of the-bolt 10 is held substantially flush with the vback of the voperating Patented July 22, 1919.

lever, as shown in Fig. 5, by the lug 11 which then engages the circumferential channel 8, a portion of the said channel being widened to form a slight shoulder, as at 16, which in conjunction with the pressure of the spring will prevent the bolt from unduly turning, which otherwise might be induced by the vibration incident to a moving train.

When it is desired to lock the lever and prevent rotation on its pivot a key 17 is inserted in key- ways 18, 19 and 20 formed in the end of the bolt 10 whereupon the bolt may be turned until the lug 11 registers with the horizontal channel 9, when the spring 18 will force the bolt forward until its movement is arrested by the said lug striking against the rim 21, at which point the lug, being in the path of the circumferential channel 7 is given another turn, when the bolt will be locked in engagement with the lever which cannot then be released without the use of the key. A suitable slot, not shown, is cut in the rim 21 to permit the lug 11 on the bolt 10 to pass through. From the back of the lever there projects a lug 22 which, when the lever is operated, by pressing on the handle portion 23, strikes a stop lug 24, formed on the brackets 3, and arrests the movement of the lever, which on return movement thereof strikes against the web 5 which forms a stop for the lever in its normal position of rest. The end of the lever opposite the handle may be provided with any suitable means for connecting the lever with the thing to be operated, in the present instance I have shown the end of the lever bifurcated, at 25, and perforated, at 26.

From the foregoing description of my invention, it will appear obvious that in addition to the positive locking mechanism which it embodies when the evice is einployed in connection with mechanism for operating a water closet, a decided and important advantage lies in the fact that when the closet is made inoperative and a user attempts to operate it he will at once observe that the mechanism has been locked, and knowing this to be the case a person would not be apt to use force, which frequently would be done if the locking mechanism were located out of sight of the operator, resulting, often, in damaging the closet parts.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent, is

1. In a device for locking operating levers, the combination of a bracket adapted to be secured to a support, an operating lever pivotally mounted upon said bracket, and a rotatively and longitudinally movable spring actuated bolt adapted to engage said lever independently of its pivot to lock the lever against rotation thereon.

2. In a device for locking operating levers, the combination of a bracket adapted to be secured to a support and having a pivot formed thereon projecting laterally therefrom, an operating lever rotatively mounted upon said pivot and having a perforation therein, and a rotatively and longitudinally movable spring actuated bolt carried by said bracket adapted toy engage said perforation to prevent rotation of said lever.

3. In a device for locking operating levers, the combination of a bracket provided with a pivot thereon and adapted to be secured to a support, a member having a bore provided with two circumferential grooves connected by a corresponding longitudinal groove; each of said grooves being in open communication with said bore, a bolt movable rotatably and longitudinally in said bore, a spring located in said bore arranged to force the said bolt forward, the said bolt having a projecting lug adapted to traverse the said grooves and to be held in engagement with either of said circumferential rooves against the action of said spring, an an operating lever mounted on said pivot and having a perforation therein adapted to receive the said bolt thereby to restrain the lever against rotation on its pivot.
