JAMES MCGILLIVRAY, 0F SOUTH CHICAGO, ILLINOIS.
VALVE DEVICE.
' Application led July 7, 1919.
To all 'whom z' may concern Be it known that I, J AMES MCGILLIVRAY, a citizen of the United States, residing at South Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Valve Devices, of which the following is a specification.
The present invention is an improvement on the construction of the valve-device of my Patent No. 929,238, dated July 27, 1909, and has for its objects simplification of that construction and rendering it less costly to produce.
In the accompanying drawings, Figure 1 is a view in vertical sectional elevation, on line A-A, Fig. 2 or Fig. 3, of a valve-device embodying the present improvement; Fig. 2 is a plan view of the same; Fig. 3 is @a section on line B-B, Fg l; and Fig' 4 is a broken view illustrating a section on line CC, Fig. 1.
The casing 5 is provided, in the same plane .between its lower closed and upper end, with diametrically- opposite ports 6 and 7, shown as internally-threaded nozzles for coupling with one, as the nozzle 6, a pressure-inlet pipe, and with the other, as the nozzle 7, an outlet pipe; and between these ports, at right angles thereto, the casing is provided with a nozzle-like port 8. The interior of the casing is slightly tapered toward its closed end to be itted by a corresponding tapered solid rotary valve 9, having a stem 10 on its outer end carrying an operating handle 12 and supported by a setscrew 11 extending through the casing against its opposite end. A bar 13 is securely supported to extend across the valvestem on opposite spacing posts 14 screwed into a reinforcing flange 15 formed about the open casing-end, and affords a bearing for a set-screw 16 working centrally against the end of the valve-stem, whereby any wear on the valve and the casing may be taken up, on loosening the set-screw 11, by operating the set-screw 16 to properly seat the valve in its casing.
A port 17 extends through the valve in position by properly rotating it through a quarter turn, to register, in one position, at its opposite ends respectively with the ports 6 and .8 and in another position with the ports 8 and 7. In the position of the valve represented in Figs. 1 and 3 it closes the inlet-port 6, and the valve-port 17 connects Specication of Letters Patent.
Patented June 8, 1920.
Serial No. 309,014.
the ports 8 and 7 to permit pressure-medium to return by way of the port 8 from the point of performing its work and discharge through the valve and the port 7. By rotating the valve through a quarter turn to register the opposite ends of the valve-port respectively with the ports 6 and 8, the pressure-medium passes by way of the ports 6, 17 and 8, to the point of performing its work.
In the inner wall of the casing are formed lengthwise thereof Land in line with each other, at opposite sides of the outlet-port 7,
a pair of pockets 18 and 19, each of one-half the area of the mouth of either port 6 or 7 and at 45 degrees from the port 7 there is formed a similar pocket 20 in the casing- Wall. Passages or bores 21 and 22 lead through the body of the solid valve 9 from one side thereof to the opposite side toward which they converge, as shown in Fig. 1, in order that when the valve is in the position illustrated in the last-named figure, wherein it closes the inlet-port 6, these passages will register at their diverging ends, respectively, with the pockets 18 and 19, and at their opposite ends with the port 6. A similar passage 23 (Fig. 3) leads from midway between the ends of the valve-port 17 through the valve, so that when the latter is rotated through a quarter turn from its illustrated position, that passage will register with the pocket 20 to connect therewith the valve-port. VThese pockets are provided for balancing the valve, in each of its two positions, to prevent binding thereof under the pressure-force exerted against it and thus render more easy its operation by turning the handle 12. Thus with the inlet-port 6 closed, as represented, the pressure-medium fills the pockets 18 and 19 through the passages 21 and 22 and counteracts the pressure at that port against the valve; and with the valve turned to register its port 17 with the work-pressure port 8 and inlet-port 6,
possible in the details of construction thus specifically shown and described, and I do not intend by illustrating a. single specific or preferred embodiment of my invention to be limited thereto; my intention being, in the following claims, to claim protection upon all the novelty there may be in my invention as broadly as the state of the art will permit. c
I claim: Y
1. A balanced valve-device comprising a casing provided with an inlet-port, and an outlet-port in the same plane, and a discharge and return-port, pockets in the inner casing-Wall at opposite sides of the outletport, a solid valve rotatably seating in the casing and containing a port connecting said inlet and discharge, and return ports in one position of the valve and said discharge and return and outlet-ports in another position thereof, and passages extending convergently through the valve to register at their divergent ends with said pockets and at their opposite ends with the inlet port when closed by the valve.
2. A 'balanced valve-device comprising a casing provided with any inlet-port, an outlet-port and a discharge and return port, all
in the same plane, pockets in the inner casing-wall at opposite sides ofthe outlet-port and a third pocket in said wall ad'acent one of said first-named pockets, a soli valve ro-r tatably seating in the casing and containing a port connecting said inlet and discharge valve, and a passage extending throug the valve from the port therein to register with said third pocket when the valve is in the position of opening the inletort.
