UNITED STATES PATENT EEICE.

GEORGE SHELLEY, OF WILKES-BARRE, PENNSYLVANIA.

HYDRANT.

SPECIFICATION forming part of Letters Patent No. 260,904, dated Julyll, 1882.

Application led March 3, 1882. (No model.)

To all lwhom fit may concern.-

Be it known that I, GEORGE SnELLEY, a citizen of the United States, residing at Wilkes- Barr, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Hydrants; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in hydrants, and has for its object a hydrant that will not freeze, and one that will be efficient and simple in all its operations; and it consists in the construction and arrangement ot' the several parts, as will behereinafter fully described, and specifically pointed out in the claims.

In the drawings, Figure lis a side view, and Fig. 2 is a vertical section, of a hydrant constructed according to my invention; and Figs.

3 and 4 are detail views, showing the means I employ for elevating and depressing the discharge-pipe.

The outer casingof my hydrant is composed of the central cylinder, A, the upper cylinder,

A', the lower cylinder, A2, and the top piece,

A3. The top piece, A3, is secured to the upper cylinder by bolts. The upper cylinder is secured to the middle cylinder by set-screw a,

passed through threaded opening in cylinder A', and bearing against upper portion of the cylinder A. 0n the inner rear side of the upper cylinder I provide a lug, a', the under side of which forms a square shoulder, which rests down on the top of cylinder A, as shown. The middle and lower cylinders arev secured together bya threaded joint. The lower portion of the cylinder A2 is reduced in size, forming the pipe a2, which is formed with a male thread to provide connection for the supply-pipe. The inside ofthe upper portion of the pipe a2 is cut with a female thread to receive the threaded end of tube b. The tube b is screwed into the inside of upper portion of pipe a2, and it is extended upward nearly to the joint of the lower and middle cylinders, as shown. In

the outer sides of the tube b', I providea series of two or more grooves, b', extended from near the top of the tube. These grooves may be made an inch or more long, as desired. These grooves are designed to convey otf the water contained in the discharge-pipe when the supply is shut on", and the manner in which these grooves operate in connection with the plunger on lower end of discharge-pipe to carry off the water will be hereinafter fully described.

b2 is an opening leading out through the cylinder A2 near its bottom.

The front o f the upper cylinder, A', is formed with the opening c, through which is passed the discharge-nozzle, and this opening is elongated vertically to permit the upward and downward play of the discharge-nozzle as this nozzle, in connection with thedischarge-pipe,

,is elevated and depressed.

The front portion of the top piece, A3, is cut away to provide passage for the handle, and so as to permit the motion of the handle from side to side, as is required in the operation of my device. 'lhe top piece also is cut with an annular bearing, c', for the top of the circle carrying the curved cams, as shown.

d is a disk. It is provided on its upper and lower side with semi-round ridges or projections extended across the disk and slightly beyond it on either side. These ridges are placed one above the other on opposite sides of the disk, and beyond the edges of the disk they form a perfectly-round rod, through which I cut inclined slots d2 d2.

e is the handle. It is connected to the circle e', which is placed and` bears between the annular bearing c' of top piece and the top of upper cylinder, A'. On the inner side of circle e', I provide two threads, e2 e2, which are curved with and extend from upper to lower sides of the circle e. The inner side of these threads c3 is made in the are of a circle of proper size to permit them to pass freely over the edge of the disk d, and the ends ofthe threads are formed a sufficient distance apart to permit the passage between'them of; theridges or projections d' on disk d. These threads e2 work in the inclined slots d2 in the ends of the ridges or projections d' on disk d, and raise and lower said disk and the dis- IOO . I .I I I i charge-pipe, nozzle, &c which are properly connected, as will be described, as the handle e is turned from side to side.

d3 is a rod made fast to disk d, and extended down and formed with its lower end threaded and screwed into top ot' T-jointf. The nozzle f is connected to side of the said T-joint, and extended through the opening in upper cylinder, and the discharge-pipe]c2 is screwed into lower end of said T-jointf.

g is the plunger, secured by threaded joint to the discharge-pipe f2, and operating within the lower cylinder, A2. This plunger is formed with a shoulder, g', below whichthe outer side of theplungeristhreaded,formingthe threaded extension which receives the annular washer g2 and jam-nut g5, as will be described.

g2 is a washer made to dt snugly the sides of the cylinder A2, and secured up against the shoulder g' by jam-nut g5. This washer g2 prevents the waste water from getting into the cylinder A, and also secures for the plunger a steady action and prevents wear ot' both the plunger and insideot the casin g. This washer may be readily replaced when worn.

g3 is an annular cup-washer, secured to under side of plunger and held by jam-nut g4. This washer fits closely the sides of the tube b, and there is space let't between the sides of the upper portion of this washer and the inner sides of the plunger, so that when the pressure of the water is on it the washer hugs closely the sides of the tube and prevents all leakage. Vhen the plunger is forced down in the operation of closing th'e hydrant this cup-washer straddles the grooves b and permits the water which is left in the discharge-pipe to pass out.

h is a valve cast on inner side of plunger and connected intwo or more places, so as to leave space for the water to pass freely when the hydrant is turned on. To the under side ot' this seat I tix proper packing h. The seat and packing are made of sufficient diameter to cover the opening ot' tube b when the hydrant is shut down, as will be described.

The operation of my deviceis simple, and will be readily understood on reference to the drawings. When the plunger, Sac., are in the position shown in Fig. 2,the water passes freely up and out of the nozzle. Then when the handle c is turned and by its connection with the disk d forces the discharge-pipe, plunger, 85o., downward, the seat and packing rest down over the opening of tube b and shut oft the supply of water. In the action of shutting oft' the water by depressing the plunger the cup-washer g3 is pressed down and straddles the grooves b', and the water contained in the discharge-pipe runs out through the said grooves b into the cylinder A2 and escapes through the opening b2, thus obviating the trouble arising by freezing ofthe water in the discharge-pipe. Ordinarily' no vwater will get in the cylinder A outside the discharge-pipe f2,- but in case any should get in there by reason of leakage or otherwise it will tlow out through the opening b3, which I provide for such purpose.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1si 1. In a hydrant having the cylinder A2 and inletpipe b, the combination, with the plunger g, having the annular shoulder g and threaded extension, of the jam-nut g5, nut g", annular washer g2, and cup-washer g3, substantially as and for the purposes set forth.

2. The combination, with the plate or disk d, connected with the discharge-pipe, and provided in its sides with inclined slots d", of' the inclined threads e2, iitted within the circle e', rigidly connected to the handle e, substantially as set'forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE SHELLEY.
