I Specification of Letters Patent.

Patented July 13, 1909.

Original application filed February 5, 1906, Serial No. 299,529. Divided and this application filed April 9,

. 1909. Serial No. 488,861.

' T all whom it 1mg concern:

Be it known that I, Eccnn'r H. GOLD, a citizen of the United States, residing at Chicago, in the county of Coolnand State of Illinois, have invented certain new and useful Improvements in Heating Systems, of which the following is a specification;

T he invention relates to a heating system particularly adapted for railway cars in which steam is taken from a source of hi h pressure, wh1ch,'however, may be variable, as 15 the pressure in the tram plpe in car heating systems, and circulated at a lower uniform ressure through suitable coils or other radiating devices.

One of the principal objects of the invention is to control by a single controller a. plurality of coils or radiators such a way that one or more of such radiators may be closed without interfering with the maintenance of the desired conditions in the remaining radiators.

vide means for keeping the. thermostat at a non freezing temperature. regardless of whether said radiators are open or closed.

I accomplish these urposes by interposing between the source 0 so ply and the radiator or radiators a controlling device comprising an inlet valve and a thermostatic membcr for operating the same and providing also a conduitwhich leads from the low ressur'e side of the inlet valve into proximity with the thermostatic member of the controller, this conduit having a valve which can be set toregulate the flow of fluid therethrough.

The present application relates particularly to an arrangement in which the conduit referred to has no efiective heating function and to an arran ement in which such conduit, whether it as this function or not, is interposed between the common supply pipe of a plurality of radiators and the thermostatic member of a single controlling device which controls the flow of heating fluid to said radiators. The broader features'of the invention herein disclosed are claimed in my co-pcnding application, Serial No. 299,529, filed February 5, 1906, this applicatio being a division of such prior application.

The invention is illustrated in the accompanying drawings, wherein Ifigore 1 is a perspective view of one form of heating system suitable for carrying out A further object of the invention is to prothrough the controlling device, and Fig. 3 a sectional plan on line 3-3 of Fig. 2.

Like characters of reference indicate like parts in the several figures of the drawings. Referring to the drawings, A represents the train pipe or other source of supply of steam at high pressure.

The controlling device is represented generally by the letter B.

C, D, E and F are radiating coils which preferably discharge freely to the atmosphere and maybe of different length shown. The coils might, of course, be of the same length. a

G is a common supply pipe which sup lies all of the radiators with steam taken tom the train pipe A and maintained at a uniform lower pressure by the agenc of the controlling device to be describe hereinafter. i H is a conduit or loop which leads from trollor B.

Any desired form of thermostatic con trollor may be employed for controlling the inflow from train pipe A in accordance with thermostatic conditions at the discharge end of loo H. I have shown a suitable form of contro ler in Figs. 2 and 3. This dc ice comprises a casing which is divided so as to form a high pressure chamber 5 with which the train oipe A communicates, and a low pressure 0 amber 6 between which is a port controlled by a valve 7; and a chamber 8. In the bottom of the casing is tapped a pipe 9 to which is screwed a casing 10 in which is located a thermostatic member 11 consistiu of a receptacle containing a "olatile fluif. Resting on the thermostatic memheris asrod 12, the reduced portion of which 13 engages with a lever 14 on a rock shaft '15, carrying a lever 16 which similarly engages with the stem 17 of valve 7. The rock shaft mav pass the invention. Fig. 2 a vertical section.

pipe G to the thermostat chamber of condinary manually operated globe villa-e20.

Any other sort of valve might. be employed. The thermostat has the usual ad usting screw 31.

The separate radiators are preferably provided with the restricting valves 22 which may be adjusted as required. The radiators may also have the manually operated valves by means of which they may .be closed against the inflow of steam.

The operation of the heating system described is as follows: The steam from train pipe A flows-into low pressure chamber 5 and thence past valve 7, supposin this valve to be open, and into supply pipe Supposing valve 19 to be open the steam will pass from pipe G into such of the radiators as are open in amounts determined by the relative positions of valves 22, which valves are ordinarily set so as to maintain the desired amount of steam for the particular radiator. Preferably, these radiators are open to the atmosphere at their discharge ends so that the pressure in them does notrise above atmospheric pressure. The vosume of steam in the radiators will obviously depend upon the position of valves 22. The steam from supply pipe G will also pass through loop H to the thermostat and if in suflicient volume, will act upon the thermostat to cause'the closing or throttlingpf valve 7. The amount of steam passing to the thermostat may bedctermine by a proper settin of valve 20. It will be seen, therefore, that the controlling means is of-such a character as to accommodate itself automatically to variations in the amount of radiating surface under steam.

- If one of the radiators is closed, this causes a rise in ressure in the supply pipe and consequent y a rise in pressure inloop resulting in a shutting down of valve. 7. The pressure in the common supply pi e G is consequently automatically ad uste so that there is no excess in the remaining radiators, and cons uently no loss of steam. If valve'19 be close or if all the separate valves 23 be closed, valve 19 being-merely for convenience in shutting off the whole system, there will still enough steam pass to.

the thermostat to keep it at a non-freezing temperature in cold weather. I

It will be understoo' that the various valves will be set so as to adjust the System to Iarg particular requirements.

not limit myself to the particular devices, constructions and arrangements shown, as modifications might be. devised which would come within the inventipn, as defined by the claims. I do not, however, claim the inventions claimed in my prior application referred'to above, intending in the present application to'claim suohinven- ,tions specific to the arrangements here. shown which are not claimed in the prior application.
