SPECIFICATION forming part of Letters Patent No. 396,326, dated January 15, 1889.

Application filed May 22, 1886. Serial No. 203,046. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES CARR, of the city of Boston, county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Hydrants; and the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification, and to the letters of reference marked thereon.

The nature of my invention relates to improvements in the class of hydrants which are generally similar in operation to that of my patent of September 17, A. D. 11878, No. 208,072.

The invention consists in the improved construction, arrangement, and combination of the several parts, substantially as hereinafter more fully set forth and described.

lVith reference to the drawings, Figure 1. is an elevation of the hydrant. Fig. 2 is a corresponding sectional elevation, the plane of section being central. Fig. 3 is an elevation of the head and a cap-holding bolt and nut. Fig. at is an elevation of the sleeve forming part of the swivel-joint in the main-valve screw-stem. Fig. 5 is a plan of the supplementary valve, its stem, and its hinge or pivotal connections. Fig. 0 is a plan of the head. Fig. 7 is a sectional elevation of the intermediate frame for valves and related parts, and shows the main, supplementary, and waste valves in their respective relations to each other. Fig. 8 is a corresponding plan. Fig. 9 is a full-size sectional view of the Wastevalve and related parts. Fig. 10 is the frictional lever or two arms of the tilting wastevalve. Fig. 11 is a front elevation of the waste-valve. Fig. 12 is the journal-pin and frictional wrist or wrists of the waste-valve lever. Fig. 13 is a sectional elevation of valveseats, &c., for main and supplementary valves. Fig. 14 is a front view of case-seat, journalbearings, &c., in one piece, of the waste-valve. Fig. 15 is a sectional plan of the waste-valve.

Like letters refer to the same or corresponding parts in all the figures.

Figs. 3, 4, 6, 10, 11, l2, l5, and 14 refer in common to hydrants having the supplementary valve and to the plain hydrant, or hydrant having no supplementary valve.

Fig. 9 refers only to the plain hydrant, though thewaste-valve is alike in both.

Fig. 13 illustrates the double valve-seat, and is for comparing with the single seat in Fig. 9.

1, 2, 5, 7, and 8 illustrate the hydrant with supplementary valve, though the parts above the intermediate. piece, B, or valveframe, as also the main valve and waste, are common to both that and the plain hydrant.

A is the stock.

B is the valve-frame or intermediate tion.

0 is the base.

D is the inlet for attachment to the main pipe.

E is the delivery-nozzle for attachment to hose, &c.'

F is the main valve.

G is the supplementary valve.

H is the waste-valve.

I is the cage and seat for waste-valve.

K is the head.

L is the cap.

M is the frost-case.

N is the screw part of the valve-stem, of

SEC-

composition.

0 is the sleeve part of the stem and its swivel-j oin t.

P is the iron part of the main-valve stem.

Q is the foot on main valve which serves to open the supplementary valve.

R is the supplementary-valve stem.

S S are the main-valve guides.

T is the supplementary-valve seat.

V V are hangers, to which the supplementary valve is jointed or pivoted.

V is a composition disk between the upper composition and the lower iron parts of the valve-stem N P.

The main valve F closes against the flow and pressure of the water. It is made of circular sections, of leather or other elastic substance, confined about the rod P, between the upper and lower iron followers, by means of a nut-,Q. When the supplementary valve is employed, the nut Q is elongated and forms a foot to the main valve and stem to bear against, press open, and hold open the supplementary valve. The lower part of the valve-stem may be iron, and is marked P.

Its upper end is formed into a screw. The upper part of the valve-stem N is the main screw, by means of which. the main valve F is operated, and may be of brass or composition. It has a head upon its lower end, preferably with two rims or collars, as shown. It is provided with a sleeve, 0, fitting over the head and screwed and pinned to the upper end of lower part, P, with a composition disk, \V, between the parts i and P. The screw part N has an upper part turned smaller than the screw, to fit the stuffing-box located above the screw-thread. The upper part beyond is made square, and carries a loose collar, resting upon the shoulder formed by the termination of the round part, which collar is a stop,which finds a stopping-place against cap L to limit the opening of the main valve. This collar is larger than the opening in the cap. The usual pentagon or other shaped head to receive the operating-key is soeketed upon the top end of the square part and pinned on, and ismade to form a suitable finish by being fitted to a corresponding opening in the cap L.

The stuffing-box is located in head K, (see Fig. 2,) and the main nut for operating screw part N of the main-valve stem is located in the lower end of a pendent partof head K, and both are made of composition and retained in position, preferably by having the iron of the head cast upon them and their suitable projections. The head K is bolted with a water-tight joint to the top flange of the stock A. The head has bolt-sockets cast upon it to retain the nuts of the cap-bolts, by

- means of which the cap is bolted to the head,

as see Figs. 2, 3, and 6.

Suitable screw-nozzles are provided, as see E, Figs. 1 and 2, with screw-caps to be used when the hydrant is not in use, one of which in Fig. 1 is unscrewed and hangs by its guardchain by the side of the hydrant.

The supplementary valve and its operation will be understood from the drawings, and is similar to that shown in my patent before alluded to. It is, however, differently hinged, in having its pivot below the level of its center, by which means it is operated more nearly centrally in the chamber, so improving the freeness of the water-way. Another important difference is that it is hinged or pivoted to a separate intermediate section, B, of the hydrant, which is small and convenient to handle and fit up complete with this and the other Valves before taking its final position in the hydrant, and being bolted together therewith.

The hangers V for the supplementary valve are preferably cast in one piece with the intermediate section, B, referred to.

The supplementary valve is made of less specific gravity than water, by which quality it floats to its seat. The flow of water also assists its closing, while its opening is accomplished by the foot Q on the main valve pushing it open as the main valve descends from its highest position to the position of full opening.

Fig. 2 shows the main valve elevated and the supplementary valve at its point of closing. The stop g, in the upward movement of the stem N, by coming in contact with the cap L, limits the movement of main plugvalve F at its full-open point, and consequently, through the foot Q, limits the upward movement of the supplementary valve to its full-open point, or, which is the same, the intermediate point of its travel. lVhen the cap L is removed, the screw-stem N has a further upward travel until the sleeve 0 meets the pendent sleeve-stop on head K, at which point in the operation the supplementary valve G will have come to its seat, after which the head K may be unbolted and removed, together with the valve-stem and main valve F, if desired, for repairs or other purpose.

Figs. 7 and 9 show the main valve near the point of closingviz., at the point where it begins to open the waste-valve, and almost instantly closes, leaving the waste-valve fully open. The waste-valve proper is marked H. There are, however, several parts-viz, the two arms or lever X X, seat, guard-fingers, and journal-bearings for valve pivots or journals, journal-pin Y, and wrists Z, all forming what I call the waste or waste-valve. The guard-fingers (see particularly Figs. ll and 15) form a case protecting the valve and valve-seat of the waste from obstructions.

The waste is constructed as follows, viz: ll, the valve, embraces the wrist Z like a band. The upper part of the band, I), is controlled and pressed toward the lower part by means of screw 0, so clamping itself (the valve) to wrists Z with greater or less tension or friction, as desired. A rod, (1, if desired, may extend to near the head of the hydrant, whereby the adjustment may be made by simply removing the head. However, this adjustment need very 'arely be made after the first at the setting up in the factory. The rod may serve as additional closing-weight on the valve. The lever or double arm X X is fixed in the middle of wrist Z, preferably dividing it into two, the valve H being somewhat in the form of a horseshoe, as see Fig. 15, and embracing the wrists on each side of lever X, or vice versa. LeverX maybe fixed to wrist Z by means of a pin or otherwise, as see the hole therefor in Figs. 10 and 12. The journal-pin Y forms the axis of wrists Z and lever X, and is supported in the journalbearings formed in part I, as see drawings.

Valve H closes by its own weight and the pressure of water and any additional weight or pressure, as of rod cl. It is opened by means of a projecting continuous or annular rim or flange, e, on the main valve, which in descending on its closing movement tilts the lever by contact with arm X.

The great fault with tilting waste-valves in hydrants heretofore has been that when the main valve were down, the waste opened too far and did not close soon enoughwhen the main valve opened again. This, in fact, is a common fault with many aste-valves not of the tilting variety. In my improvement this difficulty is obviated, and still other advantages gained, as will appear. The valve-opening is limited by stop f on the waste-valve meeting stop (t on the valve-seat, so it cannot open too far. In such case, as the main valve wears down and moves on downward, the friction of wrists Z in the valve lI yields, and arm X moves on with the main valve. Thus when the main valve opens again it has no further or greater movement in which to allow the waste-valve to close than when new. Again, when the main valve is worn so far as to need repairing and is drawn upward out of the stock of the hydrant, it is always kept in linear position by guides S, and consequently finds lever X in the position indicated by dotted lines in Fig. 9, and forces it back to its normal position, as shown in same figure, where it remains with its other arm, X, in correct position to be formed and readjusted by flange 6 on the descent of the new valve to its seat.

To return to the operation of the main valveand the construction of its stem: Observe that the swivel joint, before 6X- plained, of which sleeve 0 is the prominent part, permits the main valve to find its seat and to leave it as well without causing it to have any rotary movement upon its seat. This is apparent when it is considered that the valve is not only tapered in its seat, but is very much larger in diameter than the disk \V, upon which the torsional or rotary action is first and finally taken. Vater is admitted within and allowed to escape from the sleeve 0 through holes shown by dotted circle in Fig. 2. The upper part of valve stem is shown at the lower limit of its movement. The lower part, below the broken space, and the valve are shown near the upper limit of their movement. The disk and parts are thereby well lubricated. Slight play is preferably,though not necessarily, allowed for the head of the screwlongitudinally in the sleeve. It will be observed that the intermediate section, B, has fitted to it a double seat, as see Figs. 13 and 2, when the supplementary valve is called for, and also has the hangers V therefor fixed to it, preferably by being cast on. V hen a plain hydrant without supplementary valve is called for, this intermediate piece is fitted with a single main seat, as shown in Fig. 9, and has no hangers Y; but in either case it is fitted with the waste complete... In the case of the supplementary-valve hydrant, also, the upper and lower flanges for bolting to the stock and the base, respectively, are placed eccentrically with reference to each other, so affording convenient space within the base for the hangers V of the supplementary valve. Drainage-holes are made (see Fig. 3) in the pendent part of head K.

The broad flanged intermediate section, with a space broader than its depth between the flanges, ait'ords the best protection to the waste=delivery, while the necessary proximity to the lower flange makes that flange a defleet-or an d d ispcrser of the waste-water stream, so preventin any considerable washing away of the earth about the base.

The intermediate section, as constructed with its two flanges for bolting to stock above and base below, having fixed to it. the mainvalve guides, having the main-valve seat, the

supplementary-valve seat, the waste-valve seat, and wasteway-ori iice, the supplementaryvalve hangers, and all three valvesmain, supplementary, and waste valvefitted to it complete, and all adjusted betore bolting to its position in the hydrant between the stock and base, is a very important invention and combination of devices. affords important facilities and conveniences in the fitting and setting up in the factory never before provided. It brings nearly all working and co operative parts into view and conveniently accessible position in the assembling and setting up of the hydrant.
