IMPRovEMEN-r |N coNNEcTlo'Ns Fon STEAM-RADIATOR;

.Speciiication forming part of LettersPatnt No. 154,-5uldated September 1, 1874; application filed v March 17, 1874-.

Be n knownthat I, JOHN H. MILLS, of'

Boston, in' the county of Suffolk and State of Massachusetts, have -invented certa-in new and useful Improvements in Connections to Steami` Radiators; -and I do herebydeclare thei'ollowing to be a full, clear, and exact description o'f `the invention,':such as will. enable vvothers skilled in the art to which it pertains to make'and use it, reference being had to the accompanying drawings, which form part of thisspecitication. 'l

My invention relates to improvements in the* connectionsto steam-radiators; and consists. in the combination, with an overhead steamsupply pipe,- of a Isingle connection and its valve entering @the bottom of the radiator," as will herein be more fully shown and described.

On the drawings, Figure l represents a ground plan, Fig. 2 represents aside eleva tion, and Fig. 3 represents a perspective view, of my invention. u v

Similar .letters 'refer to similar parts wherever they occur on the dierent parts of the` drawings. p

-Heretofore it has been common to employ two or more connecting -pipes for radiators heated by steam, one of which pipes was used for the admittance of the steam, and another one for the discharge of the condensed water. It has also been common to use two valves for each radiator for the same purposes. This is objectionable on account of expensive pipings, iittings, and valves. v l

To avoid' his, difficulty and extra expense,- I arrange and combine, with an, overhead steam-suppl'ypi-pqa single connection and a single valve that enters the radiator at its lowest point, as shown in the accompanying drawing, onr which a represents a steam-radiator, and ban overhead steam-supply pipe. A single connecting-pipe, c, provided with a single valve orcut-oft, d, establishes a communication from the supply-pipe'b to the bottom or lowest part egofthe radiator a., -as

d shown, in the drawings. Thelsin'gle connect? ing-pipe o'is'placed in an inclined position,as

shown-in'Iiig. 2, in such aV manner that the,

valve or cut-oi4 d is a littlel higher than the end of the pipe o where it enters the supply- `pipe b, so that the condensed steam may iiow unobstructed from the radiator a through lthe lowerpart o f the pipe o, and at the same timeallowthe-steam from the overhead pipe b to enter the radiator through the upper part of the single pipe c. A .The extension b' of the supf vplypipe b serves for the purpose of conducting the steamto another radiatoren a st oryj below, and `also for the conveyance of the con# v densedfsteam flom' the radiatora.. I- Thus'it 'will' beseen that-I am able to use a single connecting-pipe audits valve from the overhead supply-pipe, for the purpose of conveying the steam to the radiator,a1nl`to allowthe'` condensed steam to exit therefrom without obstruction, and thereby dispense with additional pipes and valves.

I donot claim the use of a single pipe and valve, when arranged in combination with an underhead supply pipe, as shown in C. A. Wilsons patent of September 4,1860, as I use my single pipe and valve in combination with an overhead supply-pipe., by which the acl-- vantage is obtained of letting the steam and condensed-water travel unobstructed in .one and the samedirection. l

' Having thusv fully described the nature, construction, and operation of my invention, I wish to 'secure by Letters Patent, and claim- In combination with an overheadrsteam- '.snpply, b, of a single pipe, o,.and its valve d entering the bottomof radiators, as and for the purpose herein set forth and described.

In testimony thatI claiinthe foregoing I have hereunto set my'hand this 10th day of March, 'li-57a;v

JOHN H. MILLS.
