NON-FREEZING HYDRAN'I.
Specification of Letters Patent.
Patented Mar. 11, 1919.
. Application filed July 10, 1916. Serial No. 108,445.
comprehends those of the anti-freezing type having facilities for automatically discharging the fluid remaining in the stand pipe, after termination of the service flow.
The fundamental object of this invention is to provide a hydrant of the character designated, having a secondary valve controlling the inlet orifice of an eduction pipe and automatically operable to a closed position during the period of service flow, and to an open position when such flow is discontinued, to efiect adrainage of the residue fluid which, during extreme climatic conditions, either becomes stagnant, germ impregnated, and consequently, a menace to health, or freezing causes bursting of the stock, and other annoying hydrant difiiculties.
Further objects of this invention are to design a hydrant having a'secondary valve, the open or closed position of which de pends entirely upon hydraulic pressure, said valve being so disposed as to automatically resume an open positionsimultaneous with the termination of the service flow; and finally one simple in construction, efficient in operation, containing few parts which may be conveniently assembled-and disassembled for the purpose of installing or' making necessary repa1rs. 7
Briefly stated, this invention comprises a stock having its upper end communicating with a discharge faucet, and its lower end with a service main, a mainball valve located at the lower extremity of the stock, and operable to open and closedpositions by a vertically reciprocatory stem passing through the stock and connected at its free end by a suitable operating means, and a secondary ball valve juxtapositioned with respect to the main valve and controlling the inlet orifice of a drain or eduction pipe, the construction and arrangement of said secondary valve being such that, while the supply is suflicient to operate the latter to a closed position, the pressure exerted by the column of residue fluid in the stock subsequent to closing of the main valve is insufficient to operatively mamtain said valve, in consequence of which it will assume an inoperative position, and permit the residue fluid to drain from the stock.
In the accompanying drawings, in which corresponding parts are indicated by si1ni-' lar:reference characters V Figure 1 is a transverse vertical section of my improved antiefreezing hydrant, with parts being shown in elevation, and the valve in inoperative position; and
a Fig. 2 is an enlarged sectional view in detail, illustrating the secondary valve in a partially closed position.
In the illustrated embodiment characterizing this invention, there is shown a hydrant built up of a plurality of sections, including a relatively elongated, cylindrical section 1, externally threaded or otherwise formed at its end to receive the T shaped capping union 2, the latter having internally threaded diametrically opposed openings 3 and 4: to receive an externally threaded discharge nozzle 5, and the similarly threaded end of a suitable bushing 6 'rotatably housing a shaft 7 On the outer end of shaft 7 is affixed a handle 8, or other suitable operating means. A disk 9, integrally formed with the inner end of shaft 7, carries an eccentrically positioned, laterally extending pintle 10, connected to the upper extremity of valve stem 11, while the lower extremity of the latter, which is externally threaded, adjustably supports a main ball valve 11 adapted to seat in the lower end of intermediate union 12, for this purpose formed with an internal seat 12. This union affords a connection between the lower extremity of stock 1 and one end of elbow 13, the other end thereof communicating with supply pipe W. The ball valve 1-1 may be constructed of rubber or metal,
dependent on the exigency of the situation, as will 1 .be readily understood without further discussion. A spider '14:, integrally formed with the lower end of stock 1, functions as a guide during the operation of seating and unseating the valve.
Communicating with the union 12 and extending upwardly and outwardly therefrom, is a nipple 15, internally threaded contiguous its outer end to receive the externally threaded valve plug16, which is formed with a valve chamber 17, said chamber having its lower end closed by a guide plug 18,provided with transversely extending diametrically opposed passages 19, for a purpose hereinafter to'be explained. An opening 20, located intermediate passages 19, accommodates the valve stem 21, integrally formed With a secondary ball valve 22, operatively located within the valve chamber 17. The wall of plug 16 surrounding the upper end of chamber 17, is arcuate in contour, afl'ording a seat 23 for the valve 22, when the latter abuts openin :24, within which is positioned the inlet end of an eduction or drain pipe'25. The stem 20 of the valve 22 directs its seating and unseating movement through the chamber 17, and effects proper seating. Plug 16 and its incident valve structure, are
protected by a hood 26, threaded on the stock 1 adjacent its lower end, as clearly shown in Fig. 1 of the drawings.
A hydrant, constructed in accordance with the above, operates as follows Presuming the main valve 1.1 to be in a closed position, as shown in Fig. 1, rotation of the operating means will downwardly actuate valve stem 11 and, unseating'the valve connected therewith, permit the supply fluid to pass upwardly through the stock and'discharge through the nozzle 4. As the supply fiuid ascends the stock, it will enter passages 19 and, seating valve 22, close'the inlet orifice of eduction pipe 25. Upon restoring main valve 11 to its initial position, thus discontinuing the service supply, the
1 pressure exerted by the column of residue fluid in the stock being insufficient to maintain valve 22 in its seated position, it will a drop to an inoperative position, as shown in Fig. 1 of the drawings, and, opening the inlet orifice of eduction pipe 25, permit the residue fluid to pass through passages 19, chamber 17, and thence through said pipe 25 to any desired point. Of course, in this connection, it is obvious, owing to the Weight of valve 22 and its angle of location, it will readily respond to the supply or head pressure, while on the other hand, the weight of the column of residue fluid being much less than the head pressure, and incapable of maintaining said valve in closed position,
will permit it to assume an inoperative one. 7 From the foregoing structural outline, 1t
willbe seen I have designed an anti-freezing Copies of this patent may be obtained for fivecents ea'ch, by addressing the Commissioner of hydrant of an extremely simple nature em-. 7
