SPRINKILING AND FLUSI-IING HYDRANT.

Specification of Letters Patent.

Application filed June 17, 1913.

Patented Feb. 16, 1914. Serial No. 774,109.

To all whom it may concern Be it known that I, FRED B. MUELLER, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Sprinkling and Flushing Hydrants, of which the following is a specification.

This invention relates to an improved sprinkler and flushing hydrant, and has for its principal object to provide a hydrant for attachment to the city main or supply pipe independently of the usual fire hydrant so that water may be drawn off for sprinkler wagons, for flushing, for contractors use, and for any other purpose without interfering with the use of the fire hydrant.

Among the more or less important objects of this invention are the followingto provide a hydrant of this character with a stop and waste cock located at the lower end of the hydrant near the connection between the same and the main, and a hose valve at the upper end of the hydrant near the surface level of the pavement and to which may be attached any suitable hose or pipe coupling; to provide means on the hydrant for opening and closing the valves independently of one another from the surface level of the pavement or street; to provide the hydrant with a curb box inclosing the hose valve and in which the valve is locked from removal by means located beneath the curb box so that the valve cannot be detached by unauthorized persons and only by removing the earth from beneath the box and lowering the same; to provide in general a simple compact structure comprising relatively few parts which may be easily assembled and taken apart, and to provide a drain for the curb box to carry off any waste water collecting in the box to a sewer or a like point of discharge away from the lower parts of the hydrant.

Other objects and advantages of this invention will be brought out in the following detailed description of one embodiment of this invention, and in the accompanying drawings in which like characters of reference refer to similar parts throughout the several views, and in which Figure 1 is an end elevation of the hydrant shown as attached to a main, parts of .the hydrant being shown in section. Fig. 2 is a side elevation of the hydrant, parts of the same being shown in section. Fig. 3 is a detail sectional view taken through the lower end of the curb box on the line 33 of Fig. 1. Fig. t is a detail fragmentary view of the side of the cover for the curb box.

Referring to these drawings, the reference numeral 10 designates the main or supply pipe to which is attached a corporation cock 11 carrying upon its outer end areducer 12 in which is threaded one end of a connectlng pipe 13. A street L 14: is mounted upon the end of the connecting pipe 13 and is adapted for attachment to the improved hydrant either directly or by the use of a connecting pipe or the like so as to enable the positioning of the hydrant at the desired p ace.

1V ith particular reference to Fig. 2 it will be seen that the L 14: is attached to the inlet end of a combined stop and waste cock 15, the latter having a supply pipe 16 attached to its outlet end and extending upwardly from-the cock 15 toward the surface level of the street or pavement. The cook 15 may be of any adaptable construction and is provided with an operating valve stem 17 which rises from the cook 15 and is elongated to dispose its upper end near the surface level of the street. The stem 17 is provided with a polygonal head 18 upon its upper end for the reception of a special wrench by means of which the cook 15 may be opened or closed.

The upper end of the hydrant is provided with a curb box 19, of any preferred form, and into which project the upper ends of the supply pipe 16 and the stem 17 The opening in the bottom of the box 19, into which projects the upper end of the supply pipe 16, is surrounded by a polygonal boss 20 receiving therein the correspondingly shaped base 21 of a hose valve 22 located in the box. The base 21 is fitted in the boss 20 and rests upon the bottom of the box providing a shoulder between the opening for the pipe 16 and the boss 20. The supply pipe 16 carries a locking ring 23 engaging against the underside or bottom of the box 19, and held in such position by set screws 24-. The valve 22 is threaded upon the upper end of the supply pipe 16 and is held from rotation upon the supply pipe 16 by the boss 20. The collar 23 holds the valve 22 from forward displacement from the boss 20 to thereby prevent the removal of the valve by unauthorized persons.

The valve 22, as clearly shown in Fig. 1, is provided with a lateral outlet branch 22 threaded at its extremity for the reception of a hose or pipe coupling, and projecting forwardly within the box and upwardly to a point near the top thereof, so that access may be readily had thereto. The valve 22 isin other respects of ordinary type and is provided with a valve stem 25 having a polygonal head for the reception of a special. wrench for opening and closing the valve 22.

The cock 15, which is embedded to a considerable extent in the earth, is protected by a hood 26 which surrounds the cock 15 and has recesses in its opposite sides through which pass the inlet and outlet ends of the cock 15. To the upper end of the hood 26 is attached preferably by threads, a pipe or casing 27 rising about the stem 17 and projecting into the box 19. The upper end of the housing or pipe 27 is threaded to receive thereon a threaded cap 28 binding against the bottom of the curb box 19 and supporting the casing 27 and hood 26 in their proper posit-ions. A locking ring or collar 29 surrounds the casing 27, is secured thereto by set screws 30 and binds against the underside of the bottom of the box. Thus the easing 27 is held from displacement longitudinally thereof. The cap 28 is provided with a suitable bushing 31 through which passes the stem 17. Thus the valve 15 is protected from the drainage of water from within the box and also from around the box.

The curb box 19 is provided with an opening 32 in its bottom and into which is threaded or otherwise suitably secured a drain pipe leading down from the box 19 and discharging at any suitable point,asinto a sewer or the like. The drain pipe 33 is adapted to draw off any overflow or waste water collecting in the box 19. A cover 34 is suitably hinged at one side of the box and is adapted to close down flush with the top of the box so that no portion of the hydrant will project above the surface level of the pavement into which the box is sunk. This cover 34, as may be seen from Figs. 1 and l, is provided with an inset portion 35 which is apertured to receive a stem 36 having a polygonal head 37 for the reception of aring by means of which the stem 36 is adapted to be turned. A locking disk 38 is secured upon the lower end of the stem 37 and against the under flat side of the inset portion This disk 38 carries a locking flange or finger 39 engaging beneath a lip 40 extending inwardly from the front side of the box to lock the cover 34 closed. The disk 38 is further provided with a recessed projection 41 into which is seated a spring 42 bearing at its outer end upon a ball 13 engaging against the lower face of the inset portion 35. This inset portion 35 has a recess 1 1 in its underside into which the ball snaps, by the action of the spring 42, to hold the disk 38 in looking position, and is pro vided with a second recess or depression 45 spaced circularly from the recess 44: and adapted to receive the ball l3 and hold the disk 38 yieldingly in an open or unlocked position.

When the device is in use and it is desired to draw the water from the hydrant it is only necessary to apply the proper tool to the head 37, turn the disk 38 by means of the head to unlock the cover 34, whereupon the cover may be raised. The hose or pipe is now attached to the branch 22*, the stems 18 and 25 being now turned to release the water from the main 10 into the supply pipe 16 and up through the valve 22 and branch 22 into the pipe or hose. hen it is desired to shut off the flow of water from the hydrant it may be done by simply closing the valve 22 and allowing the cook 15 to remain open.

The advantage of having the valve 15 is when any repairs are to be made to the valve 22, or to any parts of the hydrantbeyond the cook 15, this cook 15 serves the purpose of shutting off and preventing waste of the water from the main.

It will be understood from the above description that the valve 22 cannot be rotated to unscrew the same from the supply pipe 16, from within the box 19, until the earth beneath the box 19 is removed, the set screws 24; and 30 loosened and the collars 23 and 29 slipped down upon the supply pipe 16 and the casing 27, respectively. The box 19 must now be moved down upon the supply pipe 16 and the housing or casing 27 to disengage the boss 20 from the base 21 of the valve. The valve 22 may now be rotated and removed from the supply pipe and the box 19. It will be seen that any waste water collecting in the box 19 cannot flow through the bottom of the box down upon the supply pipe 16 and the cook 15, since the boss 20 serves as a closure for the opening which receives the supply pipe, and the cap 28 constitutes a closure not only for the upper end of the casing or pipe 27 but also for the opening which receives the pipe 27. The waste water in the box 19 must pass out through the drain 33 and be thus discharged into the sewer or any other desirable place at a distance from the lower end of the hydrant.

It is to be understood that the above description and accompanying drawings dis-' invention provided only that such construction be comprehended within the following claims.

What is claimed is:

1. A hydrant as specified comprising a lower valve, a supply pipe rising from said valve, an elongated stem rising from said valve, a curb box inclosing the upper ends of said supply pipe and said stem, a hood engaging over said lower valve, a casing rising from said hood about said stem and opening into said curb box, a cap for said casing closing the upper end thereof, an upper valve located in said curb box and threaded upon the upper end of said supply pipe, an angular boss on said box engaging the base of said upper valve to hold the latter from turning, and locking rings carried upon said supply pipe and said casing for supporting said curb box and preventing the rotation of said upper valve.

2.
