FOR HEATING BUILDINGS BY HOT WATER.

Specification of Letters Patent.

Patented Oef. .10, 1911.

Application filed August 8. 1930. Serial No. 576.02%.

In all whom it mayicoucem:

Be il. known that I, Fnmx Waxxrnu, :1 viiizen of the United Sum. residing at Highfield, in ithe eouniy of Washington and State of Maryland, have ini'eniecl new and useful Improye neiil s in A pparagns for Healing Blilifi i fllgaby Hpii later, f whieh the following 1s a 'speeilieation,

My invention t'i-lailes to an apparalua for heating huilglings hi hot water in whivh is employed a ,eomhineil retainer and expansion tank the construelion, location and funi-ti aa of which are hereinaf ter more fully ii scribed, and, in which a )paraiusr is inehuiml irreversible motor and as :uljunets whereby to regulate the'heatradiated, this being aeconii' lished by aniqiimiie action through the mfldv in'u of saigl motor upon the draft :nul

2 is a fragmentary View in vertical seetion showing uareversible motor.

1 is a water heater of an suitable pattern, and preferabl one having; a waler jaeliei surrounding the fire pot. The speeiul eonslruelion of Lhe healer iS ii'nmalerial, ii, except in general combination with olhei' fealures herein described, not, eonsiiiniing a purl; of my invention. The heater is preferably placed in the cellar as shown, the. nullutora; indicated by 2, being lllllllt'? several stories of the building above (he heater.

3 is the. pipe whiph comlupis the hot water to the radial-tors E2, and =1 the return pipe lhat leads water bank to the lower portion of the heater :1 Her it has passed through the radiatom and given olf part of its heat.

5 i. the initial water supply pipe, which may lea' from unfy suitable eouree of prosat the end near the heater 1 it is provided with a cock or faueet 6 through which water or surplusage may be (haohurgeil. interposed in the length of the supply pipe 5 h: a hand valve '7 which may e [ISNl for turning; on or shutting oil the Ilouneeted by u T -joiui' in ihe supply pi ie. is a \(ill'li'ill pipe 8 having; a valve 9, which pipe leads to what I lerm a eonihineil retainer and exmnsion tank 14] From the pipe 8 projeela iii 12 on whiehis nounleil a lNllUl-lmlfllplllilll' 'i air-pump 13. The combined retainer llilll. exp'anqlon tank 10 is fitted with a pressure gage 14. The location of lhe combine-(l reiorizonlal l'n-aneh lion inning a hand valve 16, a reversible nmlor IT and a Filftl) valve 18. The re wraihle motor acts through suitable cow inn-{haw as l T and 17*, upon the draft and l in'. :2 shows the interior ,ofithe 1110- lm' easing 1'? and he inotor proper 17, the latter mmisiing of a wheel having a series oi preferably curved wings as shown. This wheel mounted in the casing upon a horizontal axis logether with the sheave 17 around which the chain connections 17 and 17 pass. It will be understood that when the wan-1- heated it expands and that a eertain amount must pass through lhe motor, turning: the wheel in order to reach the ex pmwi'nn tank. Furthernime, when the W9;- lei rook itpnuat reiurn from the expanlull tank through the motor and t0 the S sivsn. '.ilwrel-re the aelion of the reversiiile nmlor l:'- in move the chains li' and .17 whieh pass oYi-i' .-:ln.-uves as shown. the draft ainl win-eh io \Yhieh the ehaina are connected being 1 hm- :iulmual'ieally operated.

One 'l'unelion of the combined retainer and etpamiou tank 10 is in receive and compensz lefor any excessive pressure of Water,

there lining a cushion, of air above the W8- im', the (lfiYlW ailing in the naturenf an air vessel; The air pressure is made known by the 51a ge H, anil, for any purpose whatsoever. a pressure. in excess of the natural one may be plaeeil on the water in the combined retainer and expansion tank 10 by Innnipulnl'ing the air pump. Excessive pressure is prevented by means of the safety valve. 1

The obieet of placing the combined retainer and expansion tank 10 hell-ween the eohi water inlet ulnl the 'healer ls .(ibViOllS when the operation i;-: considered. It will be remembered that when lhe system is first in be put inlo nae il. inehuling the heater, pipes and l'll1liili'0l"*. bul excluding the (.0111- i)llll'li retainer aml expansion tank. is filled with waiei. the eonnnuuieuliun hel ween the luller ninl he inlel being eloseilhy means of lhe valve f fiuppnsing the whole syslmu to be cold and eiuplv. 1hr rook 7 is opened and lhe valve 3 rinsed. The gold water flows tl.:ough the pipe 3 into the heater and through the pipe 4 to the entire system and radiators. The valve 9 is then opened, air having'been pumped into the retainer to a certain pressure as indicated by the gage 14:. The system havin been put in operation, a certain amount water will enter the retainer therefrom, the valve 7 bein still closed. Then in the event of there being any slowness in the circulation, the air in the tank will tend to restore the circulation by creatinp a balanced pressure. To effect this resn t it is obvious that the retainer and heater should be practically on the same level, and

that the former must be interposed between the supply and the heater. Apart from this, the combined retainer and expansion tank must ,be in convenient proximity to the a heater .in order that the attendant may have it under control.

Having thus described my invention, I

claim 1. In an apparatus for heating buildings by hot water,- the combination of a heater having draft and check devices, radiators, water. conducting and return pipes connectling the heater and radiators, an initial cold water supply; pipe connected with the main conducting pipega combined retainer and expansion tank also in communication with saidinitial cold water su ply pipe and interposed between the supp y and the heater,

an air pump therefor, a reversible motor interposed in the initial cold water supply pipe between the main conducting pipe and the combined retainer and expansion tank, and connections between the reversible motor and the draft and check devices of the heater, substantially as set forth.

2. In an apparatus for heating buildings by hot Water, the combination of a heater having draft and check devices, radiators, water conducting and return pipes connecting the heater and radiators, an initial cold water supply pipe connected with the main conducting pipe, a combined retainer and expansion tank also in communication with said initial cold Water supply pipe and interposed between the supply and the heater, an air pump therefor, a reversible motor interposed in the initial cold water supply pipe between the main conducting pipe and the combined retainer and expansion tank, connections between the reversible ,motor and the draft and check devices of the heater, a safety valve incommunication with the initial cold water supply pipe, and suitable valves in said pipe and its branches, substantially as set forth.
