IMPROVEMENT. 1Nl HYDRAN'TS.

vfI'O'ALL WHOM 'IT MAY CON CERN Be it'known that I, THOMAS BROWN, of Allegheny City, Allegheny county, and State of Pennsylvania, have invented Ya new and useful Improvement in Hydrants; andrl hereby declare that`the following -is a full, clear, and exactdescription of the construction and operation of thesame, `reference being had tothe annexed drawings, andto the letters of reference marked thereon.

The nature of myinvention consists in providing the stem of stop-valvesin hydrants with a screw or worm, andalso furnishing the reservoir with a nut of the 'same pitchasthe screwed stem, through which-nut the stem works and rotates, a movable cap, through which thevspout of the .hydrantp'asses, an inclined slot or groove in the-main column of the hydrant, through whichthe spout `passes and travels, being used in combination4 with the ordinary valve, reservoir, inletfpipe, supply-pipe, and spout, forthe purpose of regulatng'the supply of water, the whole being constructed, arranged, audoperatingin 'the mannerhereinafter described. Y'

' To enable others skilledin the'art of constructinghydrants'to make and'usemy. invention, I will proceed vtoidescribe its construction and operation. l A I In the accompanyingfdrawings- Figure 1 `represents a side elevation of my improvements in hydrants;

Figure 2 represents a front elevation of my improvement in hydrants.

Figure 3 represents a section of my improvementinhydrants.

Figure 4 represents' an-elevation ofrmy-improved valve, yshowing the screw o r Worm.

Figure 5 represents a section of the reservoir and inlet-pipe, showing the valve, screw, nut, andrvalve-seat.

s Figure-6 represents the inclinedslot or groove, near the t'op of main column.

Figure'represents a plan of reservoir,` showing valve-seat.

In the accompanying' drawings'- v l .A represents the main column of an ordinary hydrant.

B represents the inclined slot or groove, in which the spout moves.

C represents the movable cap, in which I maken perforation 'qual to the diameter of the spout, whichl .passes through it. 4

- D represents the' bent spout. Y Y l -Efrepresents the supply-pipe, connectedwith the `bent spout Afl), by means of a female elbow, F, which supply-pipe E is furthermore connected with the stem G otthe valve, by being screwed to it.

G represents the; hollow stem ofthe valveH. A

H represents the valve, with openings at the side, as at K.

J represents thesworm or screw-on the hollow valve-.stem Gr of the valve H.

-L represents the nut, in which the worm or screw J' passes and revolves, \vl1i ch 'nfut L is connected with the reservoir, by means o`` beingscrewed to ityas at N.

M represents the reservoir. f O represents the inlet-,pipeywhieh is part of the reservoir'M. P represents the raised Vvalve-seat, which is also partofthe reservoirM'. 'Q represents the base, which is connected with the Vrnain'column Albymeans of screws, and Valso attached -lo 'the reservoir M by means of 'the screwRand the nuts; l

T represents a ring, of gum or leather, pressed int'oa dove-tailed` recess .at the bottom 'of'valve H, which gum or leather bears light upon the raisedJalve-seat -P, Vwhen the valve H is closed.

Ipropose, for the-purpose of manufacture, making the main column A of wood, castion', or any other suitable materiali; the movable capl O fof the same' material the spoutD of veast or'wrought iron, or malleable metal;` the female elbow Feof cast or wrought iron, -or malleable metal; the supply-pipe E of-wrought 'or cast `iron; the base,'Q,'of wood or cast iron, and the remaining larticles of brass, except the joint-ring T, which 'would be of gum or leather.

. The form and mode of making the various parts-of my"improyemeutn'hydrants.,jIleave to the taste,.skill,. and judgment of the mechanic.v

`and operating asa-.nd for the purpose set forth'.

vThe operation of working my improvement in hydrants is as follows, viz: By movingrthe bent spout D around a quarter of a'evolution, which 'spbutvD moves the cap C, by passing through o. hole in it, of the same diameter as the spout D, and the spout D moves lalong the inclined slot B of the main column A. The bent spout Dby the same operation, and 'at' the same time moves around, in the same direction thc-supply-pipe E, as it is connected tothe spout D by means of the femaleelbow F, and at the same time rotates the screwed hollow stem Gr of the valve H. As the supply-pipe E is connected with the stem G, by means of being screwed into it, as at I, andthe worm or screw J on the hollow stem Gr of the valve-VH, working in the nut L, raises the valve-H and the joint-riugl'l from the face of the valve-seat P, the water from' the inlet-pipe O passes up through the valve-seat iP into reservoirM, and through openings K inv the valve H, through the hollow stem Gr, up through the supply-pipe E, and .delivers'itself from. the spout D. When suihcient water is furnished, by turning the spout back 'again to its original position, 'it operates revcrsely, and brings the valve H and joint-ring '.l down upon the raised valve-seat P, and cuts off the supply.

When the supply of water is cutoif, the spout D is over andin a direct line with inlet-pipe O.

When the supply of water is being delivered, the spout D is at right angles with the inlet-pipe O.

The inclination of the slot Bis such as to allow the spout D to rise vertically the same distance as the valve H is lifted from its seat, when the spout'is turned. A f

I do not claim operating a hydrant by the/turning of the spout, such devices being'herctofore in use; but, having thus describedthe nature, construction, and operation of my iuvention WhatI lclaim, and desire to'secureby Letters Patent, is

1. The spout D'y and pipe E, with thein'clined slot B, and movable cap C,fcombincd, arranged, and operat ing substantially as described. .l

'- 2The hollow valve H and hollow screwed stem G, with the nut L,pipe E, und` spoutD, combined, arranged,
