l IVI PROVEIVI'E NT |"N H YDRANTS.

Specification forming part of Letters Patent No. 5484'5rdated May 22, 1866.

Toall whom it may concern:

ABe it known that I, B. P. BOWER, ot'Cleveland, in the county of Guyahoga and State of Ohio, have in ventedcertain new and useful Improvenlents in Hydrants; and I do hereby declare that the following` is a full and complete description of the construction and operation of the same, reference being had to the accompan yin g drawings, making a part of this specication, in whicl Figure l is a top View of the hydrant with the cover raised. Fig. 2 is a side elevation,

with apart of the outside casing broken away to represent the inside. Fig. 3is an enlarged transverse section in the direction of the line a' w in Fig. 2. Fig. 4 is an enlarged verticali i section through the lower part of the hydra-nt. Fig. 5 is a sectional view.

Like letters of reference refer tolike parts in the different views.

My improvement relates to the man ner o'f con structing hydrants,.as hereinafter described.

4 In Figs. l, 2, and 3, A A represents the case. The part A is of a cylindrical form, or it can b'e square, and the top A forms a box, to one side of which is hinged a cover that is opened in Fig. 1 to show the inside.

round on the outside, that lit in to notches a', formed in the plate or bottom B of the box, the notches in the bottom that receive the notches a being depressed the depth ofthe plate B, whereby the plate is securely held in place. Through one side of this plate extends up a screw, C, from a bent pipe, C', shaped as seen in Fig. 2, and from this pipe extends down connecting or side pipes, D D, which are screwed at the upper ends into the pipe, and at the lower ends they are screwed into curved pipes E, that project out from a cylinder, F, in the center. The lower part of the cylinder or valve-pipe F is enlarged and haring, as at G, and is placed and screwed on the top of an induction-pipe, H, that ent-ers the case on one side, where it is connected with the main. The pipe H can be cast in one with the bottom plate, I, ofthe case, entering at one side and extending up in the center. The bottom is secured on the case by anges u and bolts a', as represented in Figs. 2 and 3.

An enlarged view of the cylinder or pipe F and its connections, with the valve arranged inside, is shown in Fig. 4,.`bei11ga vertical'seci tion.

The valve L is-coustructeth with wings z'- at Ethe lowerpart, as seen in Figs. 4 and 5, that {htin tonotches or grooves e', cutout in the valvescat e, projecting from thei nside of the-cylin der sto guidethe valve and prevent it from working or-turning round asit is openedorfclosed. Around the valve, where it comes onto the valve-seat, ispacking c, to form a close joint,

iand above this, on the Valve, is arranged fcupped packing g that formsra close joint in the upper part ofthe cylinderiwhen the valve }is open, forthepurpose as will be-herei-nufter ldeseribed.

` h, is the valve-stem attached to the-top of the `valve by means of a collar, e, that iits'into a space formed by-a washer, m, secured on the `valve by screws n, as represented. By this `means the valvc-ste1n can be turned round `without turningv the valve, and at the same l time raise or lower it, by means ofthe screwthread lon the valve-stem turning through a cap, F, screwed into the topof the pipe F. In one side ot' the cap F is a wasteway, n', j leading into thepipe F from ihe'outsid'e. The

l upper end of the valve-stem is attacher-tto a B is acircular plate with cogs or notches (t rod, la, that extends upthrough a'guid'e, r, on one side of the pipe C, through a hole in the center ofthe plate B, and to the top a key may be connected for opening and closing the Valve.

d is a jam-nut on the screw (l for holding the plate B down in place. u u are jamnuts at both ends ofthe pipes D to aid in holding them firmly in place.

The pipe or cylinder F is screwed onto the upper end ofthe pipe H, as seen in Fig. 4, there being packing t, that ts into a shoulder formed round in the pipe to make a close joint.

The manner ofoperating this hydrant as constructed and its advantages are as follows: The water coming from the main and rising in the pipe H, when the valve L is opened by turning the valve-rod 7c so as to raise the valve in to the position indicated by the dotted lines in Fig. 4, the water will run into the curved pipes E, up through the connecting-pipes D, into the pipe C, to which the hose is connected. When the water is thus running through the pipes, the valve being elevated, the pressure of water in the pipe F around the valve forces the cup packing g out against the inside of the cylinder, thereby preventing the water from rising past this point and being wasted by ruiming through the wasteway a' or around the screwstem. When the valve is turned down or closed, by reversing the motion of the screw the water in the pipes is emptied by running down into the cylinder, above the valve, and out through the wasteway n' into the case, from which it is discharged through holes b into the ground. The cup-packing g forms, also, a close joint in the cylinder, by the pressure of Water below the entrance of the pipes E when it is closed, as shown in Fig. 4. When the valve is closed or down the water is shut oii from the main and the water in the pipes discharged through the wasteway n', as described, the wasteway being below the freezing-point. By this means the water can he drawn from pipes when not in use, which is a great advantage, particularly in cold weather,

being thereby prevented from freezing, that produces much inconvenience and injures the pipes.

The valve is opened or closed, for the purpose of obtaining water or shutting it off, by raising the lid and turning the valve-rod by a key, which screws the stem up or down, raising or lowering the valve that moves vertically Awhile the valve-stein turns, the valve being prevented from turning by the edge of the wings tting into slots in the valveseat. This prevents the friction or grinding there would be on the packing c if the valve revolved with the stem.

The screw-pipe G, cross or bent pipe C', side connecting-pipes, D, curved pipesE, and cylinder F are all connected together with the valve and valve-rod, as represented and de scribed, and can all be detached together from the case by unscrewing the nut d and lifting out the plate B; then place the hand upon the cross-pipe C' and unscrew the cylinder from the induction-pipe H, when they can all be lifted out together for repair or any other pura pose, and can readily be adjusted again into place by lowering them in the case, when, by means ofthe lower end of the cylinder being Haring, it will be easily guided onto the screw on the pipe H and screwed down in place. The plate B is then put on the top, and this plate being circular, it will t onto the screwpipe C, in whatever position it may be, whether turned more orless, and by means of the notches or cogs a it can be adjusted or turned so as to fit down into the cogs a', if it does not come at first exactly down in place, so that the cogs will match into each other. This part of the hydrant being thus easily removed from and replaced in the case is a great convenience, as it requires no digging up of the ground, and is of much value in repairing the hydrant at any time.

The hydrant, constructed as described, can either extend above or be even with the ground.

What I claim as my improvement, and desire to secure by Letters Patent, is-

1. The adjustable toothed plate B, the corresponding depressions in the plate B', and the pipes C' and D, arranged in the manner and for the purpose set forth.

2. The adjustable tooth-plate B, with the corresponding depressions in the plate B', as arranged in relation to the screw-stem h and cap F', the washers m, valve L, packing g, and grooves e, in the manner and for the purpose set forth.

3. The cylinder F, with the flaring end G, pipes E, and pipes D, in combination with the packing t and induction-pipe H, arranged as and for the purpose set forth.
