SPECIFICATION forming part of Letters .Patent No. 480,313, dated August 9, 1892.

Application led March 2, 1892. Serial No. 423,444. (No model.)

To all whom, it may concern.-

Beit known that I, EDWARD J. BACHELDER, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Hydrants, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My'invention relates to a hydrant or fireplug of that kind in which the body of the plug is in the form of a hollow post or upright provided with two or more lateral outlets to which the hose maybe attached, said hydrant being provided with a main valve near its lower end, Where it joins with the street-main, to control the admission of Water from the street-main into the hydrant, through which it is conducted to the outlets to which the lines of hose are attached.

The present invention relates to devices for controlling the passage of water from the interior of the hydrant-body to the several hoseconnecting nozzles, by which the flow of water to each of said hose-openings is controlled independently of the others.

Hydrants have been made in which the several openings for the attachment of the hose are controlled by separate valves or shut-offs, so that a line of hose can be applied to or removed from any nozzle while the water is turned on through the main valve to the body of the plug; and thepresent invention consists in the novel construction of the valve apparatus for the separate hose-connections, Which is of simpler and more efcient and at the same time less expensive construction than those heretofore made, and which, furthermore, can be readily applied to existing fire-plugs which have no separate controllingvalves for the several hose-outlets.

Figure l is a longitudinal vertical section of a portion of a fire-plug embodying this invention; Fig. 2, a transverse section thereof, and Fig. 3 a plan View of the lire-plug on a smaller scale.

The body ct of the fire-plug may be of usual construction and provided with the usual screw-stem b for operating the main valve that admits Water to the plug, which is not shown, as it forms no part of this invention.

ings c for the attachments of lines of hose, being shown in this instance as having two large openings for suction-hose, anda smaller opening, as shown in Fig. 3 and indicated in dotted lines, Fig. 2, for connection with a hosecou pling of smaller diameter. At each of the hose-openings an internal valve-chamber d is provided, which partitions off the space just inside the opening from the main space in the body of the hydrant, said chamber d having a neck cl2, that ts within the opening c of the plug and is engaged with a screw-threaded hose-connecting nozzle e, as shown, thus securely fastening both the chamber d and the screw-nozzle e to the body of the plug. The chambers dare oval in cross-section to afford space for the main valve-stem b, as shown in Fig. 2, and each of said chambers is open at its lower end and provided with an internal lip or iiange cl3 around the opening, which constitutes the valve-seat for a com pression-valve f. The upper end of the chamber CZ is provided With anopening, through which the stem f2 of the valve fworks, the said stem having a'tight fit in said opening or working in a stuffing-box g, so as to prevent admission of water from the interior of the plugato the chamber CZ around the valve-stem f2. Communication between the interior of the chamber d and the interior of the re-plug can thus be afforded only through the valve-seat cl3 when the valve fis open, as shown at the right in Fig. l, and consequently when the said valve is closed, as shown at the left hand in Fig. 1, the Water is excluded from the chamber d and the connecting-nozzle e for the hose, so that a line of hose may be connected with or disconnected from the said nozzle e While the water is admitted under pressure into the body a of the tire-plug to supply another line of hose that may be already connected with another nozzle.

The valvef is shown as composed of a rigid head f3, a disk or washer f4 of rubber or yielding material to engage with the valve-seat, and a clamping-plate f5, engaged by a nut f on the reduced externally-threaded end of the valve-stem f2, and said nut locking the three parts f3 f4 f5 tightly together and against the shoulder formed by reducing the lower end The plug a, is provided with two or more openof the valve-stem.

IOO

The valve-stem f2 is internally threaded or provided with a nut to engage the threaded operating-stem h, passing through a suitable opening and stufiing-box in the cap or bonnet a3 of the fire-plug and adapted to be operated by a suitable wrench for the purpose of opening and closing the valve.

The oval shape of the valve and valve-chainber d prevents the valve from turning with the valve-operating rod h, so that the rotation of the latter in one or the other direction screws the valve up or down.

.The fhose-connecting nozzle will be provided with the usual removable cap or cover, as shown at the left hand of Fig. 1, to protect it from damage when not in use.

By this construction the parts that require accurate fitting are separate from the main body of the plug, which thus needs no machine-Work 011 its inner surface, as is the case where slide-valves are used to control the se pa rate hose-outlets or other valves Working on seats formed on the interior of the fire-plug.

The herein-described construction may be readily applied to plugs of usual construction in which no provision has been made for independently controlling the separate hoseconnecting nozzles, and may be applied to plugs already in use, it being necessary merely to make a new head or bonnet a3 for the plug and to connect the separate valve-chambers and co-operating appliances with said plug.

I claimi The combination, with the main body of a fire-plug having a removable cap or bonnet, of internal valve-chambers separable from said body and introduced therein, and hoseconnecting nozzles d, connected with said intern al valve-chambers through the said openings in the body of the plug, said internal valve-chambers having valve-seat openings at one end communicating with the interior of the plug, and lateral openings communicating with the hose-connecting nozzles and being otherwise closed, and a valve Working in each ot said chambers, and an operating-rod therefor accessible outside of the body of the plug, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
