VALVE.

Specification of Letters Patent Patented Mar.25,113.

Application fiIedDecember 10, 1910. Serial No. 596,573.

The principal objects of this invention are to provide an etlicient valve of simple construction, having means which is not only operative to selectively control its different ports, but which is arranged to contemporaneously open said ports to divide the fluid passing therethrough, or to mix two fluids, depending upon the direction of fiow through the ports of said valve, and to provide a valve wherein the operative parts he readily assembled and replaced.

The term of this invention hereinafter described, provides a three portvalve, with a stem carrying a valve plug operative to control two c said ports, and a disk gate movahle with said plug and operative to control the other port.

This invention is advantageous in that it provides a valve having a plurality of ports with a single valve stem having means 0perative to control all of the ports contemporaneously, whereby two ports may be maintained completely open to permit the unrestricted passage of fluid through the valve, while the other port may he opened and closed, or its area varied by said means without restricting the flow through said open ports, or may he actuated to etl'ect the contemporaneous control of two of said ports, to effect the opening of one while closing the other, and said means may be further actuated to completely close or open all of said ports.

This invention includes all oil'- the various novel features of construction arrange ment hereinafter more definitely specified.

In the accompanying drawings, Figure 1 is a central vertical longitudinal sectional view of a valve constructed in accordance with this invention; Fig. 2 is a plan sectional view of the valve shown in Fig, 1 taken on 12 in the casing 7 to permit vides the ports 8 and 9 which are arranged to be controlled by the valve plug 10, and the port 12 which is arranged to be controlledby the disk gate 13 which is mounted for rotation between the casing 7 and the plate It, having the outlet nipple 15 in alinement with said port 12.

The plug 10 preferably comprises the cylindrical segment which is fitted in the cylindrical chamber 17 and which has the extended lugs 18 respectively fitted to, and embracing the squared region 19 of the valve stem 20, and is maintained in operativeposition against the cylindrical wall of the chamber 17 by the spring 21, preferably formed of a non-corrodilole material, such for instance, as. phosphor bronze. Said plug 10 may be rotated to control either of the ports 8 and 9 by the rotation of the valve stem 20, which extends through the stulling her: 22 in the casing 7, and which is conveniently provided with the handle 2 rdisposed exterior to said casing.

As best shown in Fi 3, the lower end of the stem is provided, adjacent to the squared region 19, with the squared region 25 upon which the gate 13 is mounted and the reduced trunnion 26 which latter is convenientl seated in a recessed bearing 27 provide therefor in the plate 14h The gate 13 has its periphery 28 chamlered to fitthe seat 29 in the plate 14 to prevent the leakage into the outlet nipple 155, and said gate 13 is arranged to he maintained upon its seat in said plate 12 by the spring 30 which is also mounted on the squared region 25, and bears against the shoulder 31 between the respective squared regions 19. and 25 of said stem. The gate 13 is provided with the arcuate aperture 32 which is arranged to regist-erwith the port fluid through said port 12 and nip le 15, as shown in Fig. 2, and to maintain this port 12 open during substantially a quarter rotation of the plug 10 in the direction ot' the arrow indicated in said figure.

Referring againto Fig. 2 of the drawing,

the passage of it will be-seen that by the movement of the segmental plug 10 approximately 90 from the position shown in said figure in the direction of the arrow indicated thereon, a free passage will be efiected, not only through theports 8 and 9, but through the port 12 which will be maintained open during said movement of the gate 13 by its arcuate or elongated aperture 32; by a further rotation of said plug 10 and gate 13 to a position substantially 180 from the position shown in Fig. 2, all of the ports of thevalve will be closed; by rotation of the plug segment 10 and the gate 13 to a position approximately 270 from the position shown in Fig. 2 in the direction of the arrow, the ports 8 and 9 will be wide open, and the port 12 closed; and by the movement of the plug and gate from the position shown in Fig. 2 in opposition to the arrow in Fig. 2, the relative areas of the ports 8 and 12 may be varied inversely.

It will be seen that the valve above described is effective to divide the fluid passing from the pipe 34 and direct it through the respective ports 8 and 12 in, any desired proportions, or to selectively direct said flow through either one of the ports 8 and 12 as desired. It is equally obvious that said valve'may be utilized for mixing different fluids by reversing the direction of flow therethrough and connecting the respective ports 8 and 12 withpipes conveying different fluids and controlling their flow in any desired proportions through the port 9 and into the pipe 34.

It is not desired to limit this invention to the precise details of construction and arrangement as herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of the invention as defined in the appended claims.

Having thus described my invention, I claim:

1. A valve comprising a casing having an inlet and a plurality of outlets, a rotary valve plug operative to control one of said outlets, and a gate connected to rotate with said plug to control the other of said outlets, said plug and gate each being operative to close its respective outlet when the other outlet is 0 en.
