FIRE-HYDHANT DFAlN.

Specioation of Letters Patent.

Patented July 3. 1966.

Application filed March l?, 1905. Serial No. 250,531.

To all whom t may concern:

Be it known that I, GEORGE J. WILLIAMS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State ot Pennsylvania, have invented certain new and useful Improvements in Fire- Hydrant Drains, of which the following is a speciication.

My invention relates to certain new and useful improvements in fire-hydrants. and has for its object to provide means for carrying oit any waste water accumuiated therein after the closing of the valve and, furthermore, in providing means wherebv the same may be prevented from freezing through the introduction of steam.

My device for effecting the above consists, broadly, in a receptacle into which the water above the valve drains and from which it is drawn by a suitable means, such as a handpum inclosed in the casing of the hydrant, suita le connection being provided With said receptacle for the introduction of steam from a portable boiler, such as oi' a lire-engine.

In the drawings forming a part of the specication, and in which like numerals of reference designate corresponding parts throughout the several views, Figure 1 is a vertical section in elevation of my device attached to a hydrant, which latter may be of any of the Well-known forms. Fig. 2 is an elevation of the above-ground portion of the hydrant With the pump-box front removed, and Fig. 3 is a detail elevation ofthe ump.

Reference-numeral 1 esignates the barrel of the hydrant, 2 the valve-casing, and 3 the seat for the valve 4, having the usual o erating-rod 5 threaded in cap 6. The sai barrel is provided With the usual outlets 7, having means for hose connection, and the valvecasing 2 is also provided with the usual inlet 8, 'which is connected to the supply-main.

Surrounding the barrel of the hydrant is a jacket 9, extending below the surface of the ground, as designated by numeral 10, and having a base 11. This jacket is provided with a casing 12, hinged thereto at 13 ,Fig.2, and secured by any suitable means 14, and inclosed by this casing is a hand-pump 15, rigidly secured to the barrel 1 by braces 16 16.

Below the main valve 4 and exterior of the valve-casing 2 is attached a drip-pot or drainreceptacle 18, around which and the valvecasing extends braces or connections 17 17. This receptacle may be of any practical and desired form to receive, through fpipe 19, the water remaining in the barrel 1 a ter the closing ci the valve 4. A ipe 20 is attached to the side of the barrel 1 one or more braces 2] and at its upper enti has connection by pipe 22 with the pump and at its lower end with the drain-receptacle by pipe 23, the former connection being made by drain-cock 24 and the latter by a union 25.

It will be observed that the jacket 9 is cut out, as at 26, to ermit the pipe connection 2G to pass therethrough from the pipe 20 to the pump 15, and this opening permits access to the stop drain-cock 24 aforementioned and also to the steam-hose-cap connection 27 of the pipe 20.

The pump 15 1s provided with the iston 28 and check- valves 29 and 30, the va ve 29 serving as a means for preventing backiovv in the pipe 22 and the check 30 permitting the water to escape to the pump-casing an also ermitting a suction therein. The said checll 30 seats over a discharge-opening 31, formed in the lower portion of the casing. (See Fig. 3.)

The operation of the invention is as foilows: In the common type of hydrant upon the closing of the vaive the Water thereabove having no rassureV remains in the barrel, Where it is iable in cold Weather to freeze; but in this invention the accumulated water drains through the pipe 19 into the receptacle 18, from which it is drawn, throu hpipe 20, (cock 24 being open,) by the han -pump 15, accessible by the opening of casing 12. In case any moisture remains in the parts, as through neglect of thorough removal, a steam-pipe from any source, such as a steam re-engine, is attached to the connection 27, (the valve 24 preferably being closed,) and the steam so admitted forces its Way through the pipe, receptacie, barrel, and outlet 7, thawing all frozen parte and permitting immediate use of the hydrant.

It will of course be understood that varions changes may be made Without departing from the scope and spirit of the invention.

Having fully described my invention, what i claim as new and useful, and desire to secure by Letters Patent, is-M 1. In combination 'with a hydrant, of a drain-receptacle therefor, means for removing the contents from said receptacle, and means for passing steam through said receptacle and thence through said hydrant.
