To LIZ teli-uni, t my m'nfcclilt.'
Be it knownthat l'Ai.Fiti:D -A CowLEs, a citizen of the United States, and a resident lof the borough of Manhattan, city, county, and
Stateof New York, liave invented certainj new and useful Improvements in Fire- Hydrants, of wlii'e'l'i the followii'igis a specification, accompanied by drawings. i
This invent-ion relates-to an improvement 1n fire-hydrants, and hasfor its object to efl'ectually prevent freezing lof the' water which would be contained in the fire-hydrant under ordinary-conditions and subjected t'o a freezing-external temperature.
Further o b'ccts ofthe invention willheureinafter appear; and to these endstheinvention consists of a firelivdrant- `for carrying out.
the above objectsembodying the features off construct-ion. coiiibinatioi'is of elements, and
varrangeinent of parts liaviiigjthe general" inode ofv operation'substantiallyas hereinafter full ydescribcd and claimed in thisspecification and shownin the` accompanyingi drawings, in which- Figure-1 is a vertical longitudinal sectional 'view of 4a lire-hydrant. embodying the inven-v tion arranged in propel' relatioirtoa street'.y jand'sidewalk. Fig. 2 is an enlargedvertical .sectional view of the lire-hydrant Titltattachnlent. Fg. 3 is a top plan view of the pressure-gage used in connect-ion with this inven'tion. l 1
According to this invention fluid-.pressure .f
as that of air or other suit-able gas or Huid, is applied to the surface ofthe water within the fire-hydrant in 'excess-of the water-pressure g in the hydrant to force the water. down inl the pipes below the vpoint at which it would hel su )jected tofa temperature below thefreez' ing-point of water'. in this way the water -is prevented from freezing when the' h v# drant'is not in use and by releasing the lluidpressurethe water will risefin thestand-pipe of thel hydrant ready for use when required.
Referring to the drawings, represen ts n suitable city street, li is the sidewalk, and (I represents the-curbing. -.'l`he lire-hydrant l) i is arranged in the usual iiiiiniiei' adjacent the curb and is provided withf'tlie stand-pi )e ll, .connecting in any suitable manner wit 1 the water-'main l". The li vdrant provided with the usual valve G, access to which is obtained A suitable connection K. is provided'in the Specification of Letters Patent. Applicant find my 25.1905. 'smul N6. 262,141.

Obviously some features of this invention vmay be `used-without others, and the'invention may be embodied in widely-varying '.Tlierefore, without limiting the invention tothe devices shown and describedand without enuineral ing equivalents, I claim, and de'- l sire tio obtain b v'la-'tiers Patent, the following:
