IMPROVEMENT lN HVDRANTS.

Specification forming part of Letters Patent No. 194,037, dated August 14, 1877; application filed July 6, 1877.

To all whom it may concern Be it known that I, EKINS HAND, of the city of Rochester, in thecounty of Mon-roe and State of New York, have invented a certain new and useful Improvcmentin Hydrants and I'do hereby declare that the following is a full, clear, and exact description of the constructionand operation of the same, reference being had to the accompanying drawings, in which Figure 1 is central vertical section. Fig. 2 is a top view. Fig. 3 is a cross-section in line 0: as, Fig. 1. Figs. 4, 5, 6, 7, and 8 are detail views.

My improvement relates to the means for controllingand operating the valves for letting on and cutting ofi' the flow of water to the nozzles; also, to the means for letting on and cutting oft the flow of water from the main to the hydrant; and, furthermore, in the means for discharging thedead water from the hydrant to the sewer after the flow from the main is stopped.

A is the body or barrel of the hydrant, which is of ordinary form. B is a section which screws into the lower end of the barrel, and forms a continuation of the same. This section connects with the main by a lateral branch, (3. D is an elbow at the extreme bottom of the hydrant, which connects with a sewer or other discharge. E is ashortcylinder, which screws into the top of the barrel; and F is an open-topped receptacle or box on top of the hydrant, which has a hinged cover, a, secured by a clasp, which is locked when the hydrant is not in use. The cylinder E has the ordinary nozzles bb b for the attachment of hose, and these nozzles are covered by screw-caps, as usual. A diaphragm, o, is left between the cylinder E and box F, and the box is attached to this diaphragm by means of lugs d d d, Fig. 2, through which pass screws, by which means the box is easily removed. B is a cylindrical extension of the section B, which is of somewhat smaller diameter, and projects up some distance in the bottom of the barrel, as shown in Fig. 1. In this projecting portion are out two spiral slots, ff, Figs. 4 and 5, which start centrally opposite each other at the top, and extend down in an inclined direction till they reach the bottom of said projection. lindrical valve, which fits in the section B and its extension B. It is open at the top, but has a check-valve at the bottom. Its exterior is covered by leather g,.or equivalent packing,

which is close fitting to the surface in which it rests. It has in one side and near the bottom a port, h, which, when in coincidence with the branch 0, admits the water from the main into the valve, and thence up through its open top into the body of the hydrant. It also has at the top two inclined lugs, i t, Figs. 4 and 5, which rest in the inclined slots f f, and, as the valve is raised or lowered, the lugs travel in the slots, and cause the valve to turn partially around; At the top of the valve is an arched hearing, it, having a female thread, into which screws the spindle H. The spindle passes up through a packing-box in the dia-, phragm 0, consisting of a socket, j, and a hol-. low screw, 1, which inclose a head, m, of the spindle, and the spindle above the screw is formed with a square head, it, for the fitting of a wrench, by which it is turned.

It will be seen that. when the spindle is turned it will move the valve G endwise up or down, and will, at the same time, impart to it a turning motion by reason of the lugs t 'i traveling in the inclined slots f f, as before described. Therefore the port h, in moving over or away from the openingof the main, will do so in an angular direction, and very slowly, preventing sudden shock of the water, and, also obviating the lengthening of the hydrant,

which is necessary where a vertical movement alone is produced.

K is a waste-valve in the bottom of the valve Gr. It is composed of two stems, o o, with a central disk, 1), Figs. 7 and 8. The lower stem projects through a hole in the bottom of the main valve, while the upper one rests in an arched bearing, q, whose base 1* is a separate disk, which rests loosely in the bottom of the cylinder, and incloses-the head 1). This allows the parts to be removed readily, and also keeps the waste-valve in proper position. 8 is a cross-bar in the elbow D, located some little distance below the lower end of the waste-valve.

G is a hollow cy-.

When the valveG -is elevatedsoias tobring' theipor't in "line with the; opening of the main, the waste-valve will fall to place, and serve as a check to prevent the water passing downward; but when valve G is turned down to cut offihe water, then the waste-valve will,

strike the-crossbar syar'id be' opened to let off the waste waterliin thebody offilthei-hy drant into the elbow D, and thence into the sewer or other discharge. It does not strike the, cross-bar till the flow frornthe main-is fully cut oft.

L L L are segments which form valves to' the nozzles If-Ir b. They are-formed from'a' thin cylinder of metal, which is first fitted accurately to the interior of the cylinder E by being ground in, and then cut into sections of considerable length to cover the' o-pening of the nozzles. Thesesections' im-ov'e vertically.

Theyhavelugse e e, Figs. 3 and '6, throughwhich passscrews tt t,-- which are left threaded, and pass up through the diaphragm 0, having shoulders-wuabove and below the diaphragm to prevent erid movement,- and bein g squared at the top, as shown *at "0) v, for the-application o'fa' wrench by whichthey-are turned. The segments are guid edin their up-and' dow-n movement by scre-ws'w w, Fig. 6, which fit in slotswm,=' and -may be tightened u-p "at any time -to -keep the-valves tight. The use ofthe scre-ws t' t insures the-slow movement of theof bur'sti-n'gi the hose by-' suddenj sh ock of the water. O'ne special' advantage of'this form of 'the valves' is that, formingsimply rims fitting 'the' cylinder, they are very thin, and occupy "but 5 little -space,+ enabling 'the waterchamber toibem adesma-l-l; an'd yet insuring 1 suflicientpassage for the water to feedany desired number of nozzles.

The top of the elbow D, just below the waste-valve, is made beveled, as shown, to facilitate discharge of the water.
