VALVE-LOCK.

SPECIFICATION forming part of Letters Patent No. 313,211, dated March 3, 1885.

Application filed March 26, 15 84.

T 0 all whom, it may concern:

Be it known that I, MORGAN JONES, of the city, county, and State of New York, have invented a new and useful Improvement in Locks for Valves and Faucets; and I do hereby deela-re that the following is a full and eX- act description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The object of my invention is to furnish a neat secure automatic lock for a rotary valve or faucet.

It consists, substantially, of a device con structed with a lateral pin adapted to enter an aperture in the projecting head of the spig- 0t of the valve, and with a recess formed under the pin to receive a lug projecting from the fixed casing of the valve, and a springactuated bolt playing at right angles to said recess, and adapted to enter the same and engage a notch in the lug, so as to .prevent the withdrawal of the lock-pin and lock from the valve until the bolt is drawn back by means of a key adapted to engage said bolt.

In the accompanying drawings, Figure 1 is an elevation of a rotary valve or cock, illustrated as placed in a gas or water main and locked by my improved device; and Fig. 2is a transverse central section in linezvrof Fig. 1.

A represents the body or casing of a valve or faucet, and Bits spigot. The upper end ofthe spigot projects in the customary manner above the casing, and is illustrated as terminating in a square head,B,to admit of the application of a wrench thereto for opening or closing the valve. although it may be constructed in any other well-known form. This outwardly-projecting end of the spigot is pierced transversely with one or more apertures, C, and its casing A is fitted with one or more lugs, D D, projecting laterally therefrom, as shown in Fig. 2.

E is a metallic block, provided with a lateral pin, E, near its upper end, adapted to enter the apertures G in the upper end of the spigot. Beneath this pin E a recess, F, is

formed in the block in line parallel with the pin, and at such a distance therefrom as that when the pin is inserted into the hole Gin the spigot the lug D on the casing may enter the recess F in the block, so that the block will (370 model.)

thus be brought closely up to the casing,while its engagement with the casing and spigot of the valve will prevent the spigot from turning. A bolt, G, is fitted within a tubular extension, H, of the block E to enter the recess F transversely, so that its end may engage a notch in the lug, the bolt serving when thus engaged to prevent the block from being drawn off and removed from the lug. It is automatically forced outward by means of an encircling spiral spring, K, fitted within the tubular case H. The end of the bolt which is made to engage the lug is beveled on its outer face, and the end of the lug itself is also beveled or rounded off, so that when the end of the bolt projecting out into the recess F is brought into contact with the lug as the block is forced upon it, the bolt will be antomatically forced back until the lug has fully entered the recess, whereupon the bolt will come into register with the notch in the lug and automatically springint-o it by means of the tension of the spring K.; The outer end of the tubular extension H of the lockcase is left open, and the end of the bolt playing therein is threaded, so that it may be engaged by the threaded socket in the stem bya key. L, adapted to be inserted into the case H. The key-stem is fitted with an outer encircling shoulder or flange adapted to bear against the end of the case H when the key is inserted therein, so that the rotation of the key when its socket engages the end of the bolt will operate to draw the opposite end of the latter out ofthe recess F, and so disengage it from the lug D. hen the key is detached from the bolt, the latter is left free to fasten the lock E to the valve automatically, so that the lock may be applied to the valve to secure it without the use of the key; but, when so applied as that its pin shall prevent a movement of the "alve, it may not be removed without the use of the key. The duplication ofthe lugs D D and of the apertures O in the spigot permits the application of the lock upon the right or left hand of the valve,

the number or varying the direction of the apertures O the valve may be locked in any position, whether opened or closed more or less.

as may be most convenient, and by increasing I am aware that a device for looking a cock or faucet, consisting of a bolt passing transversely through an aperture pierced in the cock and continued through its spigot, valve,

5 or valve-stem, and adapted to be removed therefrom by a key, is not new, and also that a device for the same purpose has been constructed in which one arm of a right-angled .bar is made to pass through an aperture in the cut-off plug of the cock, while the other arm is made to engage a staple on the side of the casing in position to be confined thereto by a padlock.

My valve-lock is an improvement upon these devices, and

I claim as myinvention 1. The combination, with a plate or block formed with a lateral recess therein to embrace a fixed lug projecting from the casing of the valve, and provided with a lateral pin projecting therefrom parallel with the recess to enter an aperture in the valve-key, of a bolt \K, adapted to keep the bolt within its chamber,

with its end projecting into the recess, and a key, L, adapted to enter the chamber and engage the bolt, to facilitate its retraction, substantially in the manner and for the purpose herein set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
