VALVE.

SPECIFICATION forming part of Letters Patent No. 735,162, dated August 4, 1903.

Application filed February 25,1903. Serial N0. 145,049. (No model.)

To ctZZ whom it may concern:

Be itknown that LPIETRo SErT1No,a citizen of the United States, residing at Steelton, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Valve, of which the following is a specification.

This invention relates to certain improvements in valves, and particularly to that class of valves for controlling the flow of fluids in a number of directionsas, for instance, in the flow of water or other fluid to and from a plurality of cylinders having pistons actuated in opposite directions by the fluid under pressure, although it may be employed for other purposes for directingthe flow of fluids in any direction.

A further object of the invention is to provide a simple form of ported valve by which the fiow of the fluid may be positively con-- trolled by the operator without loss of any of the fluids or reduction of pressure.

With these and other objects in view the invention consists in the novel construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of a valve constructed in accordance with the invention. Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. 1. Fig. 3 is a similar view on the line 3 3 of Fig. 1. Fig. 4 is a detail perspective view of the more important parts of the valvev detached. Fig. 5 is a detail sectional view on the line 5 5 of Fig. 3.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The valve-casing comprises two members 1 and 2, having bolting-flanges 3 for the passage of a numberpf bolts, by which the two sections may be secured together, a ring of packing material being preferablyintroduced between the two in order to render the easing water-tight. The section 1 is provided with a centrally-disposed coupling member at, to which may be coupleda supply or inlet pipe for the fluid under pressure, and the fluid is introduced into the val ve-chamber through an opening 5, communicating with a similar channel or bore 6, formed in a centrally-located valve-stem 7. In the lower section 1 of the casing is an annular groove 8, into which the waste water passes and is discharged through a port or passage 9, which may be connected in any suitable manner to a discharge-pipe, or the fluid may be discharged into any suitable receptacle in accordance with the character of the mechanism with which the device is connected. At the top of the outer wall of the annular groove 8 is a shoulder 10, annular in form, and extending downwardly through this shoulder area number of openings 11, which communicate with radiating ports or passages 12, which extend out to the periphery of the valve and are connected to coupling members 13 in the form of extensions having internal or external screw-threads for connection with pipes or tubes leading to the cylinders or other vessels with which the valve is connected. the present instance six ports or passages 12 are shown as a matter of illustration, although it will be understood that the valve may be employed in connection with a greater or a less number, as may be desired, the number of ports being limited only by the size of the valve-casing.

The lower portion of the hollow valve-stem 7, which has been previously referred to, is preferably threaded and receives an internally-threaded collar or disk 14, which may be formed of Babbitt metal or the like, in order to form a packing, and the latter is located in a circular recess 15 at the central portion of the lower member of the casing.

16 designates a valve-disk fitting within the upper portion of the annular groove 8 and forming a closure therefor, said disk being provided with an enlarged annular flange 17, which fits over the shoulder or valve-seat 10, and at the center of the disk is a hub 18, fitting within the circular recess 15 and hearing against the upper surface of the packingring 14. The valve-disk 16 is provided with three ports or passages 19,20, and 21, extending completely through the disk and all arranged in the same diametral line. The pbrts 19 and 20 are so arranged as to be brought into alinement with the several vertically-disposed ports 11, which communicate with the radial ports 12, while the port 21 communicates with the annular groove 8 and thence with the discharge-port 9. The construction is such that the port 21 is at all times and under all circumstances in free communication with the annular groove 8, so that any fluid passing through said port can flow directly through the discharge-port 9. Extending from the central portion of the upper face of the valve-disk 16 is an ann ular flange orhub member 22, and resting on this is an annular shoulder 23, formed on the valve-stem 7. The valve-stem 7 has a depending finger or lug 24, which extends through an opening 25,,f0rmed in the valve-disk, a portion of the opening being formed by cutting away the outer wall of the flange or collar 22. This connection serves as a coupling means between the valvestem and the disk, so that when the valvestem is turned by its operating-lever 25 the lower valve-disk will also be moved and may he traveled until the ports are in communication with the vertical ports 11 or may be stopped at any point between adjacent ports in order to entirelycut off the flow of water or other fluid through the valve-casing.

Mounted above the valve-disk 16 is a second disk 30, having a centrally-disposed opening 31 of square or polygonal form and adapt ed to receive thelower end ofa tubular valvestem 32, the lower end of this valve-stem being cut away for a portion of its circumference, but retaining at least two of its angular walls,which fit within the opening 31 and when turned permit the turning movement of the valve-disk independent of the lower disk 16. The tubular valve-stem 32 passes through a suitable stuffing-box 33 and atits upper end is provided with a suitable operating handle or lever 34. The valve-disk 30 is provided with a port or passage 35, which may be placed in communication with the corresponding port 19 of the lower disk 16, and said upper disk is further provided with an enlarged boss 36, in which is formed a port or channel 37, opening at 38 and 39 at the lower face of the valve-disk, these openings being adapted to communicate with the ports 20 and 21,respectively, of the lower valve-disk 16.

Mounted above the disk 30 is a valve disk or segment 40, which is secured to and rotates with the valve-stem 32, and the upper portion ofsaid segment is enlarged to form a radiallydisposed port 41, communicating at its inner end with the central passage 6 of the valvestem and at its outer end opening at the lower face of the segment at a distance from the center of rotation corresponding to that of the ports 19 and 35, so that it may be placed in communication with these ports to permit the water or other fluid entering through the passage-way 5 of the spindle to pass through the several ports of the valve-disks to any one of the ports 11 and from thence to the different radiating ports 12, leading to the pipes. The enlarged portion of the disk 40 is in the form of a radiating rib 42, which plays between the vertical walls 44 formed by cutting away the lower portion of the hollow valve-stem 32 and these walls forming a stop for limiting the movement of the segment and the lower valvedisk 16 in both directions. Y

It will be noted that the segment 40 and the lower valve-disk 16 are both connected to and rotate with the central valve-stem 7, while the central disk 30 is secured to and is movable independently by the valve-stem 32 and its operating-handle. The inlet- ports 19, 35, and 41 are arranged at one side of the disks, while the corresponding escape- ports 20, 21, 38, and 39 are disposed in the same diametral line at the opposite side of the disk, and the coupling members 13, to which the several fluid-pipes are connected, are disposed in diametral alinin g pairs, so that when the valve is moved into alinement with any one or other of the pairs of ports the fluid will pass from the supply-pipe'through the central channel 5, the port 41, port 35, port 19 to any one of the ports 11 and its radiating ports 12 to the cylinder or other device with which the valve is connected, while the waste water or return from corresponding source will enter the diametrically opposed port 12 and pass upwardly through the corresponding port 11, through port 20, port 38, port 39, port 21 to the annular groove 8, and thence through the discharge-pipe 9, or in some cases the discharge-pipe 9 may be used as the supply member, while the port of the central spindle 7 may serve as the dischargeoutlet. WVhen it is desired to place the water pressure and exhaustconnections consecutively in communication with a number of cylinders or other devices, the two handles or levers 25 and 34 are grasped and moved; but under ordinary circumstances it is preferred to operate the valve in the following manner: Supposing the valve members to be in such position as to place diametrically alining ports 11 in proper communication for the supply and exhaust of the water or other fluid and it is desired to stop the flow, the handle 25 is grasped and turned to'its fullest extent or until the edge of the radiating rib 42 comes into contact with one of the vertical walls 44 at the lower portion of the valvestem This moves the ports 19, 20, 21, and 41 into position immediately above the second pair of diametrically alining ports 11, but of course shuts off the flow of water through the valve-casing, as the centrally-disposed valve-disk 31 remains in place and its ports are out of alinement with those of the other members. The second handle or lever 34 is then grasped and turned until it is disposed below IIC and in the same radial line with the upper handle, thus placing the several ports in con1- munication and establishing a new circulation through a second cylinder or other device. By this means it becomes unnecessary to place any designating marks on the upper or outer face of the cylinder to indicate the correct positions of the operating-handles; but the casing may be provided with such indicating marks as a matter of precaution, or the coupling members to which the several pipes are connected may serve a similar purpose.

The several valve-disks and the segment, together with the seat members, are ground and properly faced in orderto form fluidtight joints, and by preference brass or similar metal is used. When worn or leaking, the upper member of the casing may be readily removed and the valve-disks taken out and reground.

It will be understood that the valve may be employed for use in connection with any desired number of cylinders or other devices, the number being limited only by the size of the casing.
