IIMPRQVEMENT IN HVDRANTS.

Specification forming part of Letters Patent No. 174, ISI, dated February 29, 1876; application filed August 26, 1875.

v proved hydrant.A Fig. 2 is a'vertical sectional view thereof', somewhat enlarged. Fig. 3. shows an'improvement in the devices for op,- erating the moving water-way. Fig. eishows a water-waste box, cast in one piece with the hydrant-case; and Fig. 5 is a sectional view through w w, of Fig. 2, but showing only the hydrant-ease and waste-box.

My invention relates to certain improve ments in the manufacture of hydrants, streetwashers, 85e., whereby the construction is cheapened and facilitated and the operation simplified and improved; and the nature of it consists i'n the features of construction and combination hereinafter described and claimed.

The hydrant-case A is, except as hereinafter specified, of the ordinary or any known construction, as also the tubular pipe B, which coustitutes'a part of the moving water-way and the supply-pipe D. At the upper end of the case A I `make a slot, a, extending down the desired distance for allowing the spout B' to have the length of vertical motion required, or, as indicated at a in Fig. 3, this slot may be made in the lower end of the' cap C. It is only important that it be made at the transverse joint of the cap and case, or at the extremity of one, or at a transverse joint in one 0r the other, though obviously such slot may be made partly in one and partly in the other. One object in making this slot with an open end is, that I may be the better enabled to introduce or insert the spout B1, which, with the flange w, I cast in one piece with the head B?, by which construction I save the expense of a lock-nut and of forming any threads on the spout and head, except the connection for the pipe B; and I also prevent the removal of the spout from the hydrant unless the hydranttop be first removed. r[he head-piece B2, at

its lower end, connects with the pipe B, and at its upper end provision is made for the raising and depressing of the moving water-way and valve. For this latter purpose the ordinary swiveled head and socket b may be employed, with a screw-stem, bl, playing through la tappedvhole in the cap C, and turned by a hand-Wheel, b2, as in Fig. l, or a wrench applied to the square head b3, as in Fig. 2, or on other suitable know'n way; but for this purpose I prefer to employ the devices shown in Fig. 3, where the head B2 is made rigid with the spout B1 and stem b1. To vthe upper end.

thereof,`) will impart an upward movement to the moving water-way and valve, so as to open orotherwise operate the latter. rlhe reverse stroke may be effected by means of a spiral spring, h, arranged on the stem bl, bearing at one end against the cap or spout, and at the other end against a collar, h1, adjustable up and down on the stem by means of a setscrew, h2, whereby the elastic force of the spring may bei-regulated according to the resistance encountered' in the-.reverse or closing motion of the valve. vThe lower end of the hydrant-case A is made with a transverse diaphragm. n, cast therewith, but with a central tapped hole for the insertion of the supplypipe D, and one or more waste-holes, n', for the escape of any water which may waste into or otherwise enter the case A above such diaphragm. As illustrated in Figs. 2 and 5, a

water-waste box or chamber, P, open at its lower end, and, with a lateral slot, p, for the insertion of the supply-pipe D, is attached to the lower end of the case A by means of ra dial lugs o on the lower end of the case, and inwardly-projecting ribs or iianges o1 on the box, the lugs'o passing down the spaces o2 between the ends of the flanges o1 and the box P then being partially rotated, so thatthe lugs o shall pass under the flanges. With this construction the box P is rotated continuously along with the supply-pipe D, as the latter is screwed into the diaphragm n, but I have found it, in some respects, a preferable construction to cast the box F along with the case A, as illustrated in Fig. 4,:but when such construction is adopted the supply-pipe D must be inserted in two parts-first, the vertical part must be screwed into the diaphragm n, and then the horizontal part inserted` through the lateral` hole p', and united to the lower end of the vertical part by an ordinary screw. constitutes the valve-seat for the valve c, which latter is attached to the lower end of the pipe B, but with the usual ports c forthe in and up flow of water.. In the side of the vertical part ot the supply-pipe D I- make a waste-port, s, which, preferably, has three openings, one below the diaphragm a in the box P, and two, s1 s2, above such diaphragm. An open-mouthed sleeve, e,.is screwed onto the moving water-way above the ports c', and its lower open end comes down'around the supply-pipe D. By means 'of an inwardlyflanged screw-ring, e', which screws onto the outside of the lower open end ot' the sleeve e, I attach a cup leather or piston packing, c,

packed to ft the supply-pipe D, and packedl as against a water-pressure acting from above. f These parts are so proportioned and arranged,

as shown in Fig. 2, as that, when the valve c is seated and the supply cut off or closed, the packing c will come between the ports s1 and s2, so that the water in the pipe B will waste away through the ports c and si, either through s into the box l?, or,if by accident or design that escape should be closed, through s2 and a', or if the ports a' should be closedy any waste or surplus water above the diaphragm could escape through s2 and s, and as the valve c is raised for opening the supply the packing u is raised t0 cover or cut off the waste-port s1. sleeve e gives an annular space, as shown, around the valve-seat for the water to fow up and down through the ports, as described.

My object in screwing the flanged ring e onto the outside of the head e instead of the inside, as has heretofore been done, is that I The upper end of the supply-pipe I)-- It will be observed that the am thereby enabled to make the head so much the shorter,.thereby savin g material and making the device more compact and less cumbersome. Also, in fitting up this part of the devices th'e packing-rings u are pressed to shape and inserted in the cup-shaped cavity of the screw-ring e', so that in case of inspection or repairs they are removable with the screwring, and, being thereby more accessible, can be more-readily examined and repaired or renewed than if inserted in way formerly practiced.

No claim is made herein to a moving waterway andfspout made in one piece, nor to the devices for raising and lowering the moving Water-way shown in Figs. l and 2.

I claim herein as my' invention- 1. The stem bl, connecting with the head B2, projecting vertically through the head of the hydrant-case, in combination with a spring and collar arranged thereon inside the case, and an eccentric, g, connected to the stem b1, bearing on top of the cap, and operated by a lever, g', substantially as set forth.

2. The diaphragm a, cast in, 4and as a part `of,fthe hydrant-case A, and transversely thereto, and having a tapped hole in the axial line of the moving water-way for the insertion of the vertical part of the supply-pipe D, substantially asset forth.
