HYDRANT.

.QPECIFICATION forming part of Letters Patent No. 303,380, dated August 12,1884.

Application filed March 3, 1884. (No mrdel.)

T @ZZ whom, it may concern:

Be it known that I, JOHN RICHARDSON, of New York, in the county of New York and State of New York, haveinvented certain lmprovemcnts in Hydrants, of which the follow-V ing is a specification.

This invention relates to improvements in that class of hydrants which consist of an upright body provided at or near its base with Io a rising and falling valve, by which the iiow of water through the same is controlled, and which are also provided with overflow-valves to permit the escape ofthe standing water when the valve is closed, and with jackets to 'pro- I5. tectthe inner portion from the frost.

The invention has reference more particularly to an improved construction and arrangement of the main and waste valves, to the construction and manner of vuniting the several 2o sections of the body, and to other details of minor importance, as hereinafter described and claimed.

Referring to the accompanying drawings, Figure 1 represents a vertical central section through a hydrant having my improvements embodied therein. Fig. 2 is a horizontal section of the same on the line a: x. Fig. 3 is a horizontal section of the valve on the line y y of Fig. 1 on an enlarged scale. Fig. 4 is a 3o vertical central section showing the main valve and waste-valve on an enlarged scale.

Referring to the drawings, A represents the foot or base portion of the hydrant, of a curved tubular form, terminating at one extremity in 3 5 a horizontal inlet-mouth, and at the opposite extremity in a vertical outlet-mouth. The base is ordinarily constructed with an extended foot or support, such as shown in the drawings, in order that it may be firmly held in position.

4o ln its upper edge the base is provided with an annular groove, c, in which there is seated the lower end of the upright tubular body-section B, the j oin't between the two parts being sealed by lead, rubber, or other suitable packing material. The base portion is extended radially beyond the groove a in the form oi' an annular flange, the outer edge of which is shoulv dered or rabbeted, as shown at I), to receive and sustain the lower end of the upright tubular jacket C. This tubular jacket, commonly portion B, so as to extend therewith to or above the surface of' the ground. The upper ends of the body portion B and jacket C are seated in or against flanges formed on the under side of the upper body-section, D, which is made of an upright tubular form, as shown, and provided with any suitable approved outlet mouths or'necks, d. It is preferred to construct the body-section B of decreasing diameter toward its upper end, and to give the upper section'. D, an internal diameter greater than that of the portion B. The joint between the two parts will be luted or sealed by packing o1"` any suitable character to prevent the escape of water between them, it being essential that no water should be permitted to escape into the annular air-space. The upper end of the body-section D is closed by a top plate cast integral therewith, so as to confine the water therein,except as it may be discharged through the necks cl, or through the waste-valve, hereinafter described. y

The top of the portion D isn flanged toreceive the top or cap portion, E, of thehydrant, which is anged in llike manner and bolted firmly thereon, as shown. vided with a hinged or removable cover, F, in the ordinary manner, in order to give access to the4 valve-operating rod. The bodysection D is held downward firmly on the upper ends of the parts B and C, and the latter confined upon the base portion by means of vertical rods G, which are screwed at their lower ends into the base portion and extended upward within the frost-jacket and through the flange on the base of the portion rD, with nuts applied to their upper ends, as shown.

Passing now to the valve mechanism, it will be seen that the body B is provided with an annular valve-seat, e, to receive a verticallymovable valve, H, which is lifted against the same to stop the tlow of water through the hydrant. This valve consists, essentially, of a circular body or valve proper (the details of which will be hereinafter explained) attached This cap ispro-l IOO to the lower end of a vertically-moving or nonrotating rod or spindle, I, the upperend of which is extended through a stung-bo'x'. J, in the top of the body portion D, and swiveled to the lower end of a vertical screw, K, which is mounted in a bar, L, which is bolted fast in d of the body portion B.

Referring to the valve proper, it will be seen that it consists of an upper disk, g, a rubber, leather, or other elastic body, h, seated against the under side and projected beyond said disk and a bottom plate, i, applied below-the rub-j ber or leather to conline the same in place and subject it to the proper degree of compression.

As shown in the drawings, both plates are screwed into position on the lower endlof the upper rod or spindle, whichis 4threadedpfor the purpose. It will be observed that the'body is of enlarged diameter below the valve-seat,

so that when the valve is lowered from the,l seat the Water may iiow freely upward aroundI its periphery. `For the purpose of assisting and guiding vthe valve in its rising-and-falling motion, it is provided with an upwardlyextending cage or skeleton, k, which bears against theinner surface of the body portion B.

In order to prevent the bursting of the hy-V drant by thc formation of ice therein above the valve, it is necessary to provide means by which the water standing in the hydrant above the valve when the latter is closed may escape. passage, 0, is formed through one side of the body B at a point immediately abovethe valve. In order to close this port when the main valve is opened that the water may not be discharged through the same under pressure, I attach to the cage 7c of the main valve anupright plate, l?, which is in eiiect a secondary valve to open and close the valveport. This plate is seated in a vertical recess in the outer side of the cage, and is forced outward snugly against the side of the body by means of a rubber or other elastic sheet, Q, .which is placed behind it. The secondary valve-plate is prevented from sliding vertically with respect to the main valve by means of dowel-pins m. It is provided near the For this purpose a waste port or lower end with a port, n, as shown in the drawings. When the main valve is closed, this port n registers with the waste-port O, so that the water above the main valve may escape through the secondary valve and wasteport. When, however, the main valve is opened by lowering it from its seat, -the port n is carried downward below the waste-port and the solid portion of the plate P brought over the mouth of the waste-port, so as to close the same and keep it closed'until the main valve is again lifted to the closed posi` tion. The waste-port is continued through a pipe or tube secured on the outside of the body portion Q, this tube being arranged to extend downward into the upper end of the corresponding tube, S, formed on the base of 7 the hydrant, and adapted to be connected with a sewer or other drain^by which the waste water'may be carried away.

I claimv 1. Thehydrant-body having the main valveseat and the waste-port above the seat, in com-I bination with the downwardly-opening main valve provided with the cage having the port n, and the vertical recess in its outer side, the metal plate l?, and the intermediate elastic packing, Q, both seated in the vertical recess,

`as described and shown, whereby a close contact is maintained between the metal surfaces.

2. In combination with the body having the valve-seat and wasteport, the main valve having the waste-valve rigidly attached, the valve-spindle having an angular lower end, and a guide-bar, M, fixed in position, substantially as described, to prevent the rotation of thc valve.

3. The body for a hydrant, consisting of a tubular base, A, the body portion B and jacket C, both seated tightly on the base, the tubular topD, seated tightly upon the body and the jacket, and the rods G, extending through the jacket and secured to the base and top sections, respectively, as described and shown, whereby the rods are caused to unite the bodysections and hold the jacket firmly in place, at the same time permitting their disconnection without excavating around the hydrant.

4. In a hydrant, the combination of a base portion, A, having a waste-pipe, S, attached, in combination with the body portion B, havingl a tubular waste-pipe arranged to enter 1 the pipe S, as described and shown.

JOHN RICHARDSON.
