. IMPROVEMENT IN'HVDRANTS.

Specification `forming part of Letters Patent No.` 172.07 l, datedJanuary 11, 1,876; application led December 20, 1875. i

\ To all whom it may concern;

'reference being had to the accompanying drawing, making a part of this specification, in which (like letters indicating like parts)- Figure 1 is a vertical sectional viewof the upper and `lower parts of a wood-incased hydrant embodying my improvements, showing the hydrant-valve Vclosed and waste open. Fig. 2, by a like view of a detached portion,

shows the hydrant-valve at about the middle 'of its opening and closing motion, and with the waste closed. Fig. 3 shows `the hydrantvalve fully opened, and Fig. `4 shows certain modifications of the same improvement.

My invention relates to that class of hydrants in which is employed a moving waterway closing against tliepressure, and may be used either inclosed ina wooden case, B, asin Fig. 1, with an attachment to a block of wood or plate of metal, B1, which latter is secured in the wooden case; orthe valvecase containing the valve may be attached toia wroughtiron tubular case, A2, as shown in Fig. 4, to the upper end of which tubular case a castiron head is attached for the convenient placing of my lifting arrangement; or the apparatus thus designated may be used in connection with a cast-metal case but, whatever be the exterior case, the usual supply-pipe A is employed seated in or on the block or plate B1, as in Fig. l, or combined with a waste-box, B2, as in Fig. 4. But, referring more particularly to Figs. l, 3,- the supply-pipe A terminates in a raised valve-seat, A1, which is surrounded by the valve-case D, the lower part Dl of the chamber of which is somewhat enlarged, so that the water may have room to ow up around the valve. From thisf chamber waste-ports d extend upto a point just above the upper packing when the valve is seated. These waste-passages are preferably made through the body of the shell or case, as shown; butmere channels in the inner sur` face of the chamber, terminating at or about the same points, will perform the same funcon the valve-seat A1.

tion, though such channels are somewhat objectionable on account `of the liabilityof `the packing to work into them. The hollow moving water-way G, by a coupling, g, is connected tothe hollow stem a]` of the valve a, and the upper packing a2 is held between the anges t i', or between the end of the coupling and a flange onthe stem. Just below this packing are the ports c, and below these is a cup-.shaped valve, c, which seats, Iby suitable packing n',

thecup extend down around the valve-seat, and are packed at their end by packing e1 and angedscrew-ring e2; then, as the valve is raised, the upper packing a2 rs't covers the waste-ports d, as illustrated in Fig. 2, before the supply is opened. By a further upstroke the lower. packingwe1 is carried clear'of the pipe A1, the upper packing still cutting olif the waste. With a downstroke the operation is reversed, and the supply is cut off before the waste is opened. y

lIt will be observed that the disk-packing n is not essential to the complete workin g of the hydrant, as the upper packing a2 and lower packing c1 govern the waste and `supply completely of themselves; but it serves as an additional preventive against leakage from the supply when 'the hydrant is fully closed. These features are shown in a form somewhat modilied in Fig. 4, but not so as to change substantially their operation.

In Figs. l, 3, the annular packing-rings are of the kind known as cup-leat-hers,7 while in Fig. 4 they are of the common form of pistonvalves; also, in Fig. 4 the lower packing el is arranged so as to bear on the inside of the pipe A]l instead of the outside, as in Figs. 1, 3. The valve-case D is screwed onto the supplypipe instead of being cast on.

The waste, instead of going out over the open mouth of the valve-case, goes out at a port, p, made for the purpose; but with this construction it is not essential that the valveseat be raised, provided the lower packing e1 make a sufficiently tight joint on the inside of the supply-pipe. Hence the valve-seat may be even with or even below the bottom of the valve-chamber.

When an iron tube is used for a casing, as

The tubular sides e of broad annular iiange, b. The cup prevents the earth being filled in ,too closely to the waste-passage, and vthus gives room for the waste water to get away from the Valve, and the weight of the superincnmbent earth, bearing on the ange b, steadies the valve and hydrant in the ground, and prevents it from being raised by the frost; and for this purpose the ange b maybe ixedly attached to the. hydrant-casing at any desired point where subject to the weight ofthe superincnmbent earth.l

Preferably, however, itis made. as an attachment of the waste-box, substantially in the manner represented in Fig. 4, and, with such wastefboX, is made separate from the rest of the `hydrant for convenience in adjusting, re- 'moving and replacing'. It is simply slipped on over the outer hydrant-case after the sup- 'ply-pipe is screwed into' place, and is simply raised up-sliding freely on the outer case- 'when necessary for the purpose of renewal, repairs, 815e., to any part of the apparatus, after which itis replaced, as before.

' 'In connection with the Imoving Water-way G, yI employ a head, G', screwed thereon, hollow up to and openinginto a spout, g,jslotted as at g, and having a stem,f, which, in order to guide the water-Way in a direct line-of motion, plays in a socket, f', or other suitable guide. Pivoted in the slot g is a lever-handle, H, one end having segmental gear 7L, which meshes into a counter-gear, m,f1Xed to the hydrant-case, and the other end, h,.constituting the handle proper. When the valve below is closed the handle is held down by a latch, H', orother suitable means.

By the use of the lever-handle and segmental gear I am enabled to raise and lower the moving water-Way in a direct line, which, of itself, is a desirable feature in such apparatns, preventing strain to the connections and lessening the wear.

I claim herein as my invention- 1. An upper packing, a2, controlling the A Waste,1in combination with a lower packing, '61, bearing on the supply-pipe below the valveseat, for controlling the supply, substantially as and for the purposes set forth.

2. An upper packing, a2, to close the Waste in advance ofthe opening of the valve, a lower packing, el, bearing on the supply-pipe below the valve-seat, and an intermediate packed valve, u', combined substantially as set forth.

3. The ange b on the waste-box, as a device for steadying the waste-box, and with it the hydrant-valve and connections, by means of the -superincumbent weight of the earth thereon, substantially vas set forth.

4. The waste-box B2, sliding freely on the outer hydrant-case, and in combination therewith, substantially as set forth.

5. The lever-handle-H, having a segmental gear, h, combination with fixed counter-gear m and a moving water-Way, substantially as set forth.
