HYDRANT.

SPECIFICATION forming part of Letters Patent No. 353,581, dated November 30, 1886.

Application filed May 24, 1886. Serial No. 203,171. (No model.)

To all whom it may concern,.-

Be it known that I, GEORGE A. OGELsBY, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain newand useful Improvementsin Hydrants, of which the following is a specification.

My invention relates to that class of hydrants which are adapted for speedy removal of the valve or cock and its seat from the stock without removing the latter from the ground, and without severing therefrom the supply-pipe.

The particular features of my said invention will be more particularly set forth in the following description of its parts and their functions, and will be pointed out in the claims, reference being had to the accompanying drawings, in which- Figure l isa vertical seuction of my hydrant, a part being broken away at mid-height of stock. Fig. 2 is a like view ofthe same, adapted at top as a pavement-washer, its lower part being like the hydrant. Fig. 3 is a like view of the gland for coupling the valve-seat with the service-pipe. Fig. 4 is a like view of the valve-seat. Fig. 5 is a perspective view of the valve or cock. Fig. 6 is a top view ofthe valve and its seat. Fig. 7 is a cross-section of the same, taken through the wasteoutlet. Fig. 8 isa perspective view ofthe base-joint or the reception-chamber wall. Fig. 9 is a like View of the cast base-section of the stock clothed with the removable jacket. Fig. lOis acrosssection of the foot of the Valveseat. Fig. 11 is a top view ofthe wrench-handle on the valve-rod. Fig. 12 is a like View of the checkpiece on the valve-rod, with stops for the same on the cap of the stock.

The same reference-letters denote the same parts in all the views.

My hydrant is composed, mainly, of an outer stock or casing designedto remain stationary, and xedly attached to the supply-pipe, and of an inner detachable stationary column, to which the delivery-nozzle is attached through the wall of said stock, the nozzle being made detachable, that the column may be lifted into and out of said stock without displacing the latter, in which the column is held down by a removable cap-plate on the stocks top.

My hydrant-stock is formed of a cast-iron trunk, A, of a cast stand, L, closed at the bottom, except an angular eye in the center thereof, for admitting therein the attaching-tenen on a separate basejoint, H, and of a section of wrought-iron pipe, B, onto the ends of which said trunk and stand are shrunk in the act of casting them, so that the stock becomes thus a permanently combined structure. Upon the top of the trunk A is secured the cap-plate A by the screw-bolts c. Said stand L has in its sides the vertical slots L', through which isinserted the detachable nozzle H, either on the right or on the left side, as the situation of the hydrant may require, said nozzle being the means for connection with the supplypipe. Said stand L is provided with the removable jacket P, which is slipped onto it from below, its top abutting against the shoulder L2 on the stand. The saidjacket hasin its side the L-form slot P', in which said nozzle is admitted, and against which the jacket is turned, as shown, both for locking the jacket to said stand and for closing the surplus openings of the slots L after said nozzle has been inserted in one of them into the wall of the base-section H of the stock of hydrant. In the interior of said stock is the servicepipe column, composed of the lower section, C, provided above with the T-coupling C2, into which the exit-nozzle C3 is screwed, and of the short section C* at top of column, onto which is screwed the recessed nut C', in which the packing Q is held compressed for sealing watertight both said short section above,

and also the bearing in said nut for the valve rod R, which turns therein. The lower end of said service-pipe is screwed into the threaded top ofthe gland E, which latter is screwed onto the eXteriorly-threaded top of the valve-seat D, and it serves as the cover for the cock or plug-valve N', held in said seat by the spiral spring D Q7 inserted around the threaded pin N at foot of valve, andretained thereon by the nut D4, said spring bearing against it and against the tenon d of the valve-seat. The valve-rod C has the enlargement or socket R2 on its lower end,for engaging thereby the nipple Nz of the valve. Said enlargement fills the major-part of the cavity in said gland, the surplus space therein communicating with the pipe C and with the nozzle G3.

The valve-seat D is provided below with the annular shoulder d', and with the oppositelugs,

d, massed on the body of the tenon or cylindrical part d3, and the top of the cylindrical' Wall H of the base-joint of the stock is provided with the rim H2, having in it the notches d2, oppositely arranged, in which said lugs d may hold while the said tenon is set into said annular rim for interlocking the valve-seat with said base-joint, and also`said gland and the service-pipe to be stationary, said basejoint itself being kept stationary by the squareshouldered tenon' H4 thereon, inserted in a squarev hole made for it in the bottom of the base-section lL of the hydrant-stock. The nut h on the threaded end H3 of said tenon secures said base-j oint H against vertical displacement.

sary only to undo said cap A and the nozzle Ca, and lift said parts out of the stock, which and said base-jointare left intact in the ground. A gasket or rubber ring (not shown) is inter- `posed'between said base-joint and the foot of .the valve-seat to makethe joint between them Water-tight. p

The internal structure of the valve-seat D and of the cock or plug-valve N is as follows: The valve has a longitudinal bore in its lower end extending about half its height, and denoted by m', and it has the transverse bore or slot O, intersecting said vertical bore, which latter communicates below with the receptionchamber M in joint`H and with the inlet m2. The valve-seat D has in it the lateral opposite ways, m, leading'from said transverse bore O of the valve up into the gland E, and thence up through the service-pipe C to the exit-nozzle O3. Said valve is provided with t-he squarev nipple N2 on top, and the lower end, R, of the valve-rod has init a socket fitting said nipple, for turning the valve, as described.` Said rod is provided at top with the operating handle or` wrench R3, and a little below said handle on said rod is the arm or check-piece R', which is arranged to work in a recess or cut-away, A2, in the cap A. The'ends of said recess serve as stops Z Z', which are so situated that the valve-rod may turn only about a quarterturn from stop Z to stop Z', and that when said arm has come against stop Z', as shown in Figs. 1 and 12, the supply-water will have free course through the valve, the valve-seat, and the service-pipe, and that when said arm is reversed 'and has cometo the other stop, Z,

the supply will be shut off, and the waste- Water passages will be open, to let the caught water pass from the hydrant into the ground..

little above the valves mid-height, and regy istering with the outlet-opening n in the valveseat when the valve is fully reversed. The waste andthe supply passages are therefore all in the valve `and in its seat, and operate by reciprocation or to alternately shut oiic and turn out thesuppl y and the waste, respectively.

The device shownin Fig. 2 is similar to the hydrant described, excepting that the cap or lid A* is adapted to cover the outletnozzle C3 and the widened part A3 of the stock A.

1. The combination, with the lower part ot' the stock or stand L, cast with the exterior shoulder, L2, thereon, and having the vertical slots L arranged oppositely in its wall above its bottom, and with the base-joint H, secured to-the bottom of said standinteriorly,and provided with the attaching-nozzle H', projected through either of said slots, of the removable jacket P, provided with the slot P', opening' upward and'applied around said stand against said shoulder, and closing the unused slot in y the stand, substantially as herein set forth.

2. The hydrantvalve-seat D, having its upper end a screw for uniting thereby with the interiorly-threaded gland E, and having its lower end a slip-joint formed with a tubular tenori provided with exterior lugs adapted to tit in and interlock with-tbe top end of the iixed support H, having on it a tubular rim formed with notches` in it, the said valve-seat also `havingin it the downwardly-tapering receptacle D', extending from its top centrally through it, and the upward-curving ways m in its wall, leading'from ports at said receptacle to exits into said gland, in combination with the `plugvalve N, fitted into said receptacle,

and having in it the vertical bore lVI, intersecting with the'transverse bore O, and registering thereby with said ways, and with means applied to, the lower end ofthe valve for holding it down in said seat, all constructed IIO and cooperating substantially as hereinshown -the wall of the seat to exits at its top, and also with the waste-orifice n'in saidwalharranged between said ways and above said ports, in combination with the valve N, fitted into said receptacle, and having in it the central bore, m,intersecting with the transverse bore O, and thereby communicating with said ways, and

also having in it the vertical bore n, intersecting with the transverse bore n2, and thereby communicating with said orifice, and with means adapted to hold said valve in its seat, and means to lirnit its throw, substantially as herein shown and described.

4. The hydrant set forth, comprising the stock formed of both cast and Wrought sections, united solidly into one structure and having a cap-plate removably secured on its top, and having secured therein at its bottorn a tubular base-joint provided with a detachable inlet-nozzle projected through a slot in the wall of said stock, of a tubularjacket applied around the stock below, of an inner tubular delivery-column formed of sections, all screwed together and the Whole set on said base-joint,to which its lowest section,which is the valve seat, is fitted by means to resist turn ing, and on which it is held by said cap-plate bearing on said column, of a plug-valve titted into said seat provided with a conical receptacle therefor, and with Water-ways in its Wall having intercourse both ways with intersecting bores in the valve'adapted to let the supply up into said column and to let the Waste off, and of a rod tted to said valve as a key for turning it, all said parts being constructed and arranged with reference to removal of said column without displacing the stock, substantially as set forth.
