PUMP-VALVE.

SPECIFICATION forming part of Letters Patent No. 286,742, dated October 16, 1883.

T aZZ whom/it may concern:

Be it known that I, FRANK STOCK, Jr., of San Jose, county of Santa Clara, State'of California, have invented an Improved Pump- Valve; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to the class of pumpvalves, and to certain new and useful improvements therein.

-ro My invention consists in means for permitting and accomplishing the rotation of valve, whereby it may wear more evenly and free itself of sand and grit, as I shall fully explain.

Referring to the accompanying drawings, Figure 1 is a perspective View of my pumpvalve with a portion of the packing a broken away. Fig. 2 is a plan of the bottom of the same. Fig. 3 is a cross-section through B, packing a, valveseat A, and band D, and an elevation of the valve E. Fig. 4 is a portion of a plan and horizontal section through the legs of bridge B. Fig. 5 is an elevation of a modified form of my invention. Fig. 6'is asection through Fig. 5, showing the valve E in ele- 2 5 vation. Fig. 7 is a top view or plan of Fig. 5;

Fig. 8, a view in perspective of the valve E.

In the drawings, A represents a ring or band forming the valve-seat. a is the packing surrounding it. a 0 B is a bridge fitted down to rest upon the edge of flange of the valve-seat. C O are the straps by which. the parts are secured to the rod or pole of the pump. These straps have their lower ends formed into bolts 5 c, which passdown in grooves formed in the sides of the bridge, and through notches in the flange of the valve-seat, and through the leather packing a. A

D is a bottom band or guide fitted upon the 0 lower ends of the bolts 0, and held up tightly against the packing by means of nuts d.

E is the valve, having packing e, and lying between the sides of the bridge upon the seat A. This valve has a central stem, f, which 4 5 extends upward and plays loosely through the cross-piece of the bridge B. Upon the under side of the valve are cast radial flanges or wings g. (See Figs. 3, 6, and 8.) One side or surface of these wings is a straight one, while the other is an inclined surface tapering away from the. valve. The wings are long enough Application filed May 8, 1883. (No model.)

to extend down within the guide-band D when the valve is down to its seat, and when the valve is raised they do not rise above the top of said band, which thus acts as a guide for said wings to hold the valve perpendicular. The stem f guides said valve above.

In the ordinary construction of valves for pumps the guides by which they are directed are of such character as to prevent the valve from rotating while still allowing it vertical play. This is the case where the valve is provided with two stems, or where it has side studs moving in grooves formed in the body of the device. Having only the vertical play, any inequality in the valve-seat or packing soon increases by constant wear until the valve will no longer snugly fit its seat, and when sand or grit gets in it there is no way in which the valve can free itself; but if the valve could rotate both these difficulties would be overcome. By having a central stem, f, such asI have shown, and a, cross-piece through which the stem loosely passes, it is obvious that while permitting the vertical play the valve may also rotate. The wings 9 underneath accomplish this result. By being beveled on one side, and straight on the other, the force of the water isexerted to cause the rotation of the valve. At the same time the wings serve as a guide for the lower part of the valve, as they are confined in the bottom guide-ring, D. I do not confine myself to this precise construction of the parts surrounding the valve.

In Figs. 5 and 6 I show the valve-seat and the bottom guide-band cast in one, the bridge cast with an annular base, 12, and fitted on the bottom band through the intervention of packing h. The valve is the same as heretofore de- 0 scribed, and operates in the same manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The pump-valve E, having a central stem, 5

f, above and radial wings g on its under side,

said wings having each a straight surface and an inclined surface, in combination with a valve-seat, a guide for the stem,and a guide for the wings, substantially as and for the purioo pose herein described.

2. The pump-valve E, havinga central stem,

7, above and the radial. wings 1 below, said wings having each a straight surface and an inclined surface, in combination with the valveseat A, the bridge 13, forming a guide for the stem, and the band D, forming a guide for wings, substantially as herein described.

, 3. The pumpwalve E, hibVlI] g at central stein, f, above and the radial wings g below, having each a straight and inclined surface, as described, in combination with the valve-seat A, 10 bridge B, bottom band, D, and straps G, haw ing bolts 0, securing the whole together, substantially as herein described.

In witness whereof I hereunto set my hand.
