HlGH-PRESSUREVALVE.

SPECIFICATION forming part of Letters .Patent No. 628,671, dated July 11, 1899. Application filed December 19, T898. Serial No. 699,749. (No model.)'

To all whom it may concern:

Be it known that I, GUSTAVUS OLIvIo NEW- MAN, a citizen of the United States, residing at Riverside, in the county of Riverside and State of California, have inventeda new and useful High-Pressure Valve, of which the fol-' lowing is a specification.

My invention relates to that class of valves for use where hydraulic pressure is used under great head and is designed toproduce a V valve which, while resisting and stopping the flow ofowater under heads from very small fall up to three thousand or more feet fall, will yet at the time of opening be operated against only a portion of. the total head, wherefore the valve is easier to open than are the old forms.

The object of my invention'is to produce a Valve for high pressures which can be easily opened against such high pressures and which will have no sliding contact-points to produce friction and increase the amount of-power required to operate the valve.

My invention comprises a valve-body having a partition therein with a horizontal portion and a passage through thehorizontal porthe plate immediatelybelow to catch under the same and the flange or logs of the lower plate extending underneath the partition and catching under the same, so that when the valve-stemis drawn upward the flange or lugs will draw the plates successively upward and apart until the extension flange or lugs of the lowest plate engage with the under side of the partition, thus stopping the valvestem from any further upward movement. Openings are provided, so that when any plate is lifted from the plate next below a passage is left between the two. When the plates are together, the openings are closed. Preferably the area of the openings between the upper plate and the plate next below is equal to the efflcient area of the opening through said plate next below, and the area of the open-. ings between any two plates is equal to the area of the opening of thelower plate to be supplied through such openings, and the combined area of the openings between all the plates and the partition is equal to the area of the efficient opening in the partition.

The accompanying drawings illustrate my invention.

Figure 1 is a view partly in vertical axial section, showing my valve fully opened. The course of the water is indicated by arrows. Fig. 2 is a fragmental sectional detail of the working parts of the valve fully closed. Fig. 3 isa fragmental plan of the valve, the valvestem being out off at 3 3, Fig. 1. Fig. 4 is a view showing the ring with legs or lugs depending from it instead of a flange.

A is a va1ve-chamber in the valve case or body A, which is provided with the inletinto the yoke 3 and passes through the stuffing-box 4E in the top of the valve-body A and is swiveled into the top of the top or central plate 1 of the valve.

a a indicate the openings provided between the several plates for the passage of the water through the valve. I p

e indicates the catch-flanges of the several plates, and 6 indicates the catch .lugs or legs.

e indicates screws bywhich the legs are detachably fastenedto their .plates, so that the plates can be put together to form the valve instead of that shown-inFig. 1.

e' indlcotes a ring screwed onto the lower end of each flange to form a detachable catch thereon to allow the valve to be put together and taken apart.

The operation is as follows; The valve being closed, as in Fig. 2, we will assume for illustration that there is a pressure of one thousand feet'of water upon the valve and we have an area of twenty-four square inches, through which thewater must pass with'approximately a one-thousand-feet head. The

weight on the valve would amount to over fourteen thousand pounds and it would require a lifting force of considerable complication to control this surface and weight in the pressure on the valve is relieved to the extent of over three thousand pounds. A further upward movement of the valve-stem causes the catch of plate 1 to lift plate 1" from its seat upon ring 1", and so on until the valve is opened as wide as is desired. It is readily seen that the lifting strain is distributed by this means, and there is no friction, which is increased by the weight of the water being against one side, and there can be no water-' hammer. The flow must be steady and uniform from the start of the lifting of the valveplates. It is obvious that these valve-plates may be provided with other means of lifting one another or of telescoping them together; but it is my desire to broadly claim and protect the valve constructed of the separate plates and adapted to be operated successively one after the other to admit of the openin g independently of portions of the passageway for the water.

In high-pressure valves the seats between the plates will ordinarily be ground together; but, if desired, gaskets may be arranged between the rings;

When the first plate has been raised against the pressure of water, the water will flow through the upper openings and relieve the pressure upon the next plate or ring because of themovement of the water, and therefore in practice the opening covered by the second and third plates may be of greater area than the openings between the first and second plates, and so on as the pressure per square inch is diminished by the movement of the water.

Now, having described my invention, What I claim as new, and desire to secure by Letters Patent, is

As the valve-stem 2 is rotated by As soon as the first plate is" 1. A valve comprising a valve-body having a partition therein with a passage through the partition; a plurality of superposed plates comprising a top plate carried by a valvestem; one or more annular plates arranged below the top plate, and means connecting each plate with the plate below it to lift said plates, substantially as and for the purpose herein set forth.

2. The combination of a valve-body having therein a partition with a horizontal portion and a passage through the horizontal portion; a plurality of superposed plates comprising a top plate carried by the valve-stem; one or more annular plates arranged below the top plate; and means for connecting the plates x to allow them to separate only a given distance and thus to successively lift when the valve-stem is raised.

.3. The combination of a valve-body having a partition with a horizontal portion and a passage through the horizontal portion a plurality of superposed plates comprising a top plate carried by the valve-stem, and one or more annular plates arranged below the top plate, each of the plates being provided with downwardly outwardly extending catches; the catch ofany upper plate extending underneath the plate immediately below, and the catch of the lowest plate extending underneath the partition, so that when the valvestem is drawn upward, the catches will draw the plates successively upward until the catch of the lowest plate engages with the under side of the partition. at. A valve comprising a valve-body having therein a partition with a horizontal portion, and a passage through the horizontal portion; a plurality of superposed plates comprising a top plate carried by the valve-stem, one or more annular plates arranged below the top plate, each of the plates being provided with downward outwardly extending legs; and screws screwed through the plate into the legs to detachably attach the legs to the plates; each of the legs being provided with a catch, the catch to the legs of any plate extending underneath the plate immediately below; and the catch of the lowest plate extending underneath the partition.
