VALVE DEVICE.
SPECIFICATION forming part of Letters Patent No. 765,867, dated July 26, 1904.
Application filed November 2, 1903. Serial No. 179,429. (No model.)
To (all whom, it may concern.-
Be it known that I, CHARLns H. WATTERS, a citizen of the United States, residing at 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.
My invention relates to an improvement in the class of valve devices for controlling hydraulic pressure, though it is also useful for controlling other varieties of pressure; and my primary object is to provide a simplified construction of valve device in the class referred to whereby parts shall be rendered reversible or interchangeable for the purpose of increasing the durability of the device, whereby the need of stuffing-boxes shall be dispensed with, and whereby the dimensions of the device may be reduced to the minimum for the service it is required to perform.
Referring to the accompanying drawings, Figure 1 is a view in vertical longitudinal sectional elevation, the section being taken at the line 1 on Fig. 2 and viewed in the direction of the arrow; and Fig. 2, a section taken at the line 2 on Fig. 1 and viewed in the direction of the arrow.
A is the shell or casing, having the ports B, B, and B all shown internally screw-threaded, and within the casing is the chamber C. Each end of the casing at right angles to the ports B and B has screwed into it at opposite sides of its longitudinal center chambered plugs to b and a 7) to receive the ends of tubular longitudinally-reciprocable valvestems D and E, passing, respectively, through pairs of annular valve-seats 0 c and (Z (Z, screwed into place. The stems are provided near their relatively opposite ends with disk valves 6 e and ff, shown screwed upon the stems and fastened by nuts 11, though the valves 0 and f may be formed as integral parts of the stems, if desired. The valves 0 and f seat outwardly against the inner faces of their respective seats 0 and (Z, and the valves 0 and f seat inwardly against the outer faces of their respective seats 0 and d, each valve being provided, preferably on both of its faces, with annular packing-rings of leather or=other suitable gnaterial, let into abling the dimensions of the device to be rcduced accordingly, or, in other words, increasing the efiiciency of the valve device of given dimensions. At opposite sides of the center of each valve-stem it is provided with collars is, forming stops between which the stems are embraced by the bifurcated ends of a head Cr, keyed on an oscillatory stem H, which is journaled at its inner end in a bushing Z, confined centrally in aspider Z, formed in the casing at the port B the oscillatory stem extending out through a stuffing-box m in a plug 02, screwed into the open side of the valve-casing opposite that containing the port B and being provided with a handle I.
To explain the operation of the device, it may be regarded as being placed in position to render uppermost the port B as the inletport for hydraulic pressure, which on entering through that port separates at the divider e' thereat into two streams to flow in opposite directions to the valves 0 and e, which have been preparatorily unseated and the valves f and f at the same time seated by suitably turning the head Gr at the handle I to turn the stem H. The valves are balanced by the pressure in contrary directions against those on opposite ends of the stems. The water enters the chamber C through the valve-seats 0 c and discharges from the chamber through the outlet-port B to the engine or mechanism to be driven by hydraulic power. To discharge water, as the return water from said engine admitted to the chamber C through the port B the handle I is turned in the direction opposite that described to close the valves e e and open the valves f f, thus to permit that water to flow through the discharge-port B. Obviously, however, either port 13 or B may be used as the inlet, the primary purpose of providing the two directly opposite each other being for this reversible purpose, and the lower port B also serves for draining the valve device. \Vater that enters the chambers in the plugs c a and Z) I) does not obstruct or cushion the longitudinal movements of thehollow valve-stems, because in their movements they displace such water into the passages through them, so that there is no necessity for providing against the entrance of water into the plug-chambers, and the necessity of providing stufling-boxes, of which four would otherwise be required, is dispensed with. Moreover, the valve-stems are interchangeable by arranging the stem It in the position of the stem I), thereby furnishing to each valve a new seat when the old becomes worn, and thus doubling the life of the valve device, which is also increased by the reversibility of the ports B and B, and the valves themselves, or at least those which are not integral with their stems, may be taken off and reversed to double the life of their usefulness. These purposes are all accomplished by the simple construction of my improved valve device shown and herein described, though the details of construction may be variously modified by those skilled in the art without departure from the invention which, therefore, is not intended to be limited to such details.
Ducts 0 (shown in Fig. 1) maybe provided, if desired, to afford communication from behind the valve stem ends with the valvechamber for evacuating the plug-chambers of surplus water.
WVhat I claim as new, and desire to secure by Letters Patent, is-
1. In a valve device, the combination with a casing containing a chamber, of a passage in the casing-wall leading entirely about said chamber, an inlet-port and outlet-ports and opposite valve-seats forming pairs, a longitudinally-reciprocable stem for each pair of said seats carrying valves seating, respectively, against the inner and outer faces of the members of each pair, and a handle connected with said stems to move them in relatively contrary directions by turning the handle.
