Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed January 26, 1909. Serial No. 474,238.

To all whom it may concern:

Be 1t known that I, J AMES D. MARTIN, a

citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented a new and useful Hydrant, of which the following is a speciication.

My invention relates to hydrants or analogous structures, and particularly to a strucily detached from the stand-pipe and carry-- ing with it when so detached, a valve, thus permitting theeasy renewal or repair of the valve.

A further object is to provide the valve with a handle which in one position locks the valve to its seat, thus preventing accidental displacement, and to provide a peculiar form of valve which shall engage with the seat but not flatten out under pressure and therefore become deformec.

I further provide means whereby when the valve is closed against its scatto stop the flow of water through the lower portion of the stand-pipe, an outlet opening is left "Z unobstructed above the valve, permitting any drant to flow out therefrom and thus preventing the freezing of the hydrant.

In the drawings, Figure 1 is a side elevation of a hydrant constructed in accordance with my invention; Fig. 2 is a longitudinal diametrical section of Fig.`1; Fig. 3 is an enlarged longitudinal section of the valve; and Fig. 4 is a transverse section of Fig. 3

In the drawings,

threaded into a cap will act to force water in the upper portion of the hy- This,

relatively great depth and being a section of a hemisphere.

At its upper end the pipe 3 is screwor head 7, which is formed at its upper end with a stuiing box, 8, of any usual. or desired construction. Ex-

tending out from the cap 7 is the nozzle 9,

which is preferably formed in one piece with an upwardly extending bracket, 10, carrying at its upper end the outwardly projecting ears 11 for the pivotal support of the handle 15 as will be later described. Passing through the stuffing box 8 is the valve rod 12, which, at its upper end, is connected to a yclevis 13, formed to have pivotal engagement with the bifurcated end of a link, 14.

The upper end of this link is also bifurcated to engage with a projecting portion, 16, of a handle, 15. The inner end of the handle 15 is reversely curved as at 16 and is pivoted at its end to the ears 11 by the pivot bolt 1S. A pivot bolt 17 passes through the` handle and through the bifurcated end of the link 14. The inner end of the handle, as before stated, is curved inwardly at 16 so that when the shown in Fig. 1, the pivotal axis 17 of the link isthrown inward beyond the axialline of the valve rod 12. It will thus be seen that any upward pressure on the valve rod 12 the handle 15 inward and hold it more securely in the position shown in Fig. 1, and that in order dle 15 outward and the valve upward, the valve rod 12 must first be depressed slightly. therefore, constitutes a locking means whereby the valve is held to its seat against any accidental displacement of the handle arm 15. In other words, there is a toggle joint connection between the handle 15 and the valve rod, and the members of the toggle joint are forced beyond the axial center of the rod, thus holding them in place.

The lower end of the valve rod 12 is screwthreaded as shown in Fig. 3 and engages with the opposed valve cages, 19 and 20, which support between them the leather packing ring, 21, having the upwardlyturned margin, 22, which contacts against the inside face ofthe pipe 3, and acts as a packing for the valve. This packing ring, is, of course, annular so as to leave a central opening through which water may pass from handle is in the positionV to move the han-VA LF TO SAMUEL M. ROB- f handle isarrested yby marbre taken out the lower cage into the upper cage and so out into the upper portion ,of the pipe 3 above the valve". TheV lower end of the Acage v 20 is formed with a concaved seat adapted'to 'bear against and support a ball,'23`, pref-k erably made of rubber, or other like material, and adapted to seat snugly against the seat, G. The rod 12- passes entirely through course, by screwing up the nut, 24, the ball, 23, Ais held firmly engaged with the rod l2 -I l and with the cage 20.V Asv before noted the valve seat 6 is relatively deep and engages over a large portieri Of ,its area with the ball 23. This is for the purpose of preventing the ball from flattening out when the valve is forced down, the sides of the ball being held by the inner surface f the seat so that the ball cannot flatten and therefore become deformed, f c

Thuscthere is at no time any water in the upper portion ofthe hydrant when the valve is'V on r,its seat. Y t

The operation of my device is obvious: When the handle l5 is raised the valve will also beraised, thus permitting the passage of Water through the pipes 5,3,- and out i 40 through the nozzle, 9.` isV depressed to `its full 23 'b' i-Ow When 'the' handle extent, the ball, ears upon the seat, ,6, closing the through the stand-pipe 3, and in this Y 4,5 position the valve is locked by the toggle link, Vlll, being forced inward beyond its axial line. The opening, 27, is then unobstructed to permit the leakage Vout of water from drant. l,

The upward movement of .the handle 1,5 is limited by ya stop jlle, Fig. 2, and is so arranged that it will arrest the movement of the handle when the valve isopposi-te the port 27 vso-as to thereby close ,the latter, rand the downward or locking movement of the the free end of the latter striking the cap, as shown vin Fig. l, so that the pressure of the water in the service pipe 5 actingon the valve will not move it open, since thevaflve cannot move vas long as the handle bears l.against the cap 'Z'.

The advantages of my invention reside particularly in the ease with which the valve from the stand-pipe for repair or renewal. The cap, 7, maybe easily the deformation of the ball position shown in- Fig. 2
