I @llllmll-'KESSMHE HEATENQ: SYSTEM..
No. 812,925. Specification of Application iiled Augu Beit known that I, AMos HARRISON, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Low-Pressure Heating Systems, of which the following is a descrip: tion.
My invention relates to a system of heating apparatus wherein the heating medium con sists of a suitable vapor under low and prefF erably, a proximately atmospheric pressure.
The o ject of my improvement Ais to provide substantially automatic means for circulating such a medium at low pressure withor fan except at possibly infrequent perio in starting the operation.
To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims.
'In the accompanying like or corresponding re e dicate like or corresponding drawings, wherein rence characters inparts, Figure 1 va heating sysbeing in section to more clearly show the construction. Fig. 2 is an enlarged sectionall View. showing a part of the construction of the pressure-reducing means. Fig. 3 is a secarts. Fig. 4 is a vertical section of the pre erred generator. Fig. 5 is a trans' verse section on line 5 5 of Fig. Lt, and Fig. 6

' In the preferre forni shown in the drawings, 1 is a`generator of any suitable construction connected by a main 2 to suitable As shown in Fig. 6, the radiator 3 is connected by what is known as asinglepipef system, while in Fig. 1 the connection: with the radiator .4 indicates the two-pipe sysf tem. The two methods are shown to indicate the referred connection in each in'-I t is of course obvious' that any Letten raient. Patented Feb. 2o, 190e.

' manner is an automatic pressure-reducer comprising a casing 5, suitably connected at one end to the main; as at 6, and closed at its opposite end upon a centrally-contained tube or pipe 7. Oneend of the tube'7 forms a connection 'With,,an extension 10, preferably passing transversely ythrough the main 2,-as shown. Thus while the medium may circulate freely about the tube it'is prevented.
from passing into it. By this means the tubel is heated and the passing vpartially cooled vapor therein is increased in temperature above that which is conducted thereto. trom the radiators.
ssv
That part of the tube 7 extendin outside the casing 5 is preferably extende a' short distance above the roof ofv tlie `building ,in
which the apparatus is located, so that any air,l gas, or vapor within the tube may be freely discharged into the atmosphere.y In order to assist this action, I prefer to place upon `the projecting end of the tube an eject-v ing-cowl 8, provided with a suitable vane 9, the two being rotatably mounted to secure the most favorable action ofthe wind. In the preferred form shown the pipe 10 forms an extension or continuation of the tube 7 and is provided with a suitable trap or seal 12 and connected with a pipe 11, arranged to return any Huid arising from condensation in the s'ystem to the generator.
In'order to communicate thepartial vacuum or reducedpressure Within the tube 7l and associated parts to' the radiators and various parte oi'the system to cause the vapor to flow therein, I connect the radiators by a suitable pipe or pipes 14 to the tube 7 or extensions thereof above the highest point to which liquid' therein will rise. .If desired, automatic "air-valves 15, operated by the temperature in the usual manner, may be located at suitable points in the system to regulate the flow of Vapor in the pipes and *preventwaste v. 'I I prefer to provide a trap llineach pipe, 11 near `the generator and in 'other parts of the system Where fluid is likely to accumulate, and provide the same With drip-cocks 17, sothat the system may be drained when' A pipeflSiis provided with a valve 19 and arranged' 'to conduct'the liquid to be vapo- IOO emergency or in starting the operation.
Any preferred form of generator suitable for the purpose may be employed. Satisfacy system an( tory results may be secured by means of the generator shown in Figs. 5 and 6, made the subject-matter of a separate application for Letters Patent duly filed August 1, 1904, Serial No. 219,007.
As shown', the shell 22 is provided with one or more transversely-arranged porous beds 23 of incombustible material, which are raised to high temperature by a burner 24, ada ted for use with gas, oil, or the like. The Hui is introduced by a pipe or pipes 11 andy distributed by a foraminated annular trough 25 or, if preferred, by a. spraying-nozzle 26. (Shown in dotted lines.) The v `por generated is intimatelyinixed with tiic products of combustion from the burner, and the mixture thus formed` is passed intothe system by means of the pipe 27, connecting with the dome 28': The burner may be open to the atmosphere by means of a suitable opening 29 or other preferred means'. l
Obviously the highest economy is secured, inasmuch as the products of combustion, as wel] as the Generated Vapor, pass through the y give up their heat in their passage through the system, vas described.
Having thus described my improvement, it is obvious various immaterial modifications inay be made without departing from the spirit of my invention. Ileiiee 1 do not wish to be understood as limiting myself to the exact form and cpiistructioii shown.
