IMPROVEMENT IN HYDRANTS.

Specification forming part of Letters Patent No. 75,344, dated March 10, 1868; reissue No 6.990. dated March 14, 1876; application filed February 17, 1876.

To all whom it may concer-n Be it known that I, T. R. BAILEY, Jr., of Lockport, in the county of Niagara and State of New York, have invented a new and lmproved Hydrant Fire-Plug; and I do hereby declare the following to be a lull, clear, and exact description thereof, which will enable others skilled in the art to which my invention relates to make and use the same, reference being had to the accompanying draw ing, which forms a part of this specification.

This invention relates to improvements in the construction of lire-plugs or hydrants.

In the drawing, Figure l represents a longi tudinal central section of a hydrant accord- .ing to my invention; Fig. 2, a cross-sectionl of the same through lines w o: of Fig. l.

My invention consists in the following parts and combinations, as-hereinafter specified and claimed, wherein A represents .the hydrant-- tube from which water is discharged. B -is the horizontal section which is connected with the water-main, and which may form the valvechamber. C is a loose movable casing around the hydrant-tube D is the cylindervalya having its seat at its lower end, upon suitable elastic packing secured in agroove, as shown at a-. E is a rod having a screwthread on its upper end, by which the valve is operated. Fis a sleeve-nut enga-ged with the screw-nut on the rod E, lifting and lowering said rod as the nut is turned one way or another. This nut is turned by a wrench or crank or other suitable device on the head G.

The sleeve-nut is screwed in the cap of the hydrant by a collar and packing, under the hollow cylinder stung-box H, J is a yoke' which is attached to the rod E by a setscrew or its equivalent, and it is screwed'in the tube A, and prevented from turning as it moves up and down by projecting lugs, as shown in detail at Fig. 2.V

It will be noticed that the arrangement is 'such that the rod and valve may be raised and lowered without being rotated, thus securing a uniform and perfect bearing ofthe valve on its seat, the lpacking a remaining undisturbed.

Provision is made for the discharge of the waste water by an orifice, j, beneath the valve d, which orifice is opened and closed by a appear.

valve, g. A wing, h, is provided upon the top y of this valve. As the cylinder-valve D descends the annular vflange i on its inside striking the wing h, raises the valve, as shown in the drawing, and allows any water which may remain in the hydrant to escape down through the orifice j' and aperture K, thus preventing any retention ot' water above the freezing level.

The tube A is secured to the horizontal section B by a ring-nut, m, which contains recesses for packing-rings around the valve, as shown at rn.. Packing about the valve is also secured by another ring-nut, o, and also under the end of the tube A, as shown in the drawings.

P represents the discharge pipe, with a screw for the attachment of the base, and a cap-piece for covering the pipe when the -hydrant is not in use.

It will be observed that the casing C loosely rests upon the main B, or upon a branch projecting upward from the same. This casing extends upward, enveloping the main port-ion of the water-pipe A, at least that portion which is subterranean. Said casing extends upward and fits loosely about the plug or hydrant at the portion A. Abovefthe upper terminus of the casing C is provided the bead a upon Vthe hydrant proper. Sufticient space is left between the beada and the upper ter.- minus of the casing U to permit of sucient upvanddown play of the saidv casing C,for the purpose which will hereafter more f ully This distance between the bead and casing may be adjusted to any desired distance, thus lengthening or shortening it by means of its screw attach ment at its base.

The Vmain function of the casing U is to prevent derangement of parts Vduring cold weather by the ground alternately freezing and thawing around the hydrant or plug. This .process of lreezing causes the surrounding earth, by its expansion, to lift or upheave, and thus be liable to derange the hydrant or plug.' This upheaval'o'r movement is received by the casing rO, which, by its capability of sliding loosely up and down, will accommodate th,'.e upheaval of the earth,'above mentioned, without any liability to derange the plug or hydrant. This is the chief function of the easing C, although it likewise serves the pun pose of protection to the water-pipe A.

What 1 claim is- 1. In combination with a hydrant or fireplug, a detached and surrounding casing, C, said casing adapted to have an independent lip-and'down motion snicent to receive the entire movement imparted by the upheaval of the surrounding earth by freezing, withoutv derangement 0r disturbance of the hydrant 0r plug proper, substantially as shown.

2. In combination with a hydrant or fireplugpipe, A, the supply-pipe B, and cylinder velveand waste-valve, connected and operated suhstantiallyzas herein shown and described.

3. The combination of the hydrant or replug pipe A, supply-pipe B, valve D, casing (Land yxstuing-box H, substantially as and for .the purpose shown. p
