Be it known that I, EGEnrH. GOLD, a -citizen of the United States, residing at Shelby, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in' Automatic Heating' Systems, of which the following is `a specili- `cation.

My 'inventionrelates to a heating system, 16 in which the admission of theheating medium to 'the' radiating system is controlled by a device located within or c onnected with the. radiating system'.`

' More speciically', my device is particu- 16 larly -adaptedfor` use in connection with train heatlngsystems in which; a high pressure train'V pipe is combined with low pressure radiating pipes, the admisslon of steam from the train-'pipe to the radiating plpes be' prferabl controlled by va device whic 41s expo outside of the apartment `to be'heated.

One object of my invention is to provide simple and effective means, located w1th1n 25 a compartment'connected with the radiating system, for automatically controlling the su ly 'of'steam to the radiating system.

` g heabove object and suchl others as may hereafter lap v shownin t e accompanying drawings, 1n which-- Figure 1 is a'perspective view of one embodiment of my invention.

and an outlet chamber C. The chambers A and B are separated from the chamber C. The'supply pipe il connects through a suitable port with the inlet chamber A. The web D constituting; the top of the inlet chamber A is provided with a valve 'seat E.

Fitted to this valve seat E is a valve F pro-` vided with a stem G and also provided with I a polygonal collar, or washer, H. Screwed4 into the top of the Vvalve chamber B is a cap I provided on its Inder face with a suitable seat for engaging the washer or collar VH. Mounted upon the valve stem G between the washer H andcap I is a washer of packing material J As sl own in the drawings, the valve stem isalso rovided with a stufling.- box K, but this stu essential where the packing washer J is used.

Mounted upon the cap I and surrounding the stem G is a helical spring L, upon which ng-box is not considered rests a cap M provided on its under side with a suitable seat for the spring L. The

cap M is also provided.'4 with an upwardly proJectingstem n upon the upper end o which is screwed aV nut N, which is then r1veted in -place by upsetting the end ofthe stenrm. Thevalve casing 3 is provided, ad-

jacent to its upper edges, with inwardly Brojecting bosses 1. Mounted within' these osses and exten@ ing across the space be- 'tween .them is a pivotfbolt O. Pivotally mounted upon the bolt O is a lever P whichV is forked at opposite ends, one of the forked Vends engaging the stem m upon' the cap-M.

Extending longitudinally of Vthe dis-.

charge ipe 9 isA i stem Q which projects upward y througl. the chamber C and-is pivot'ed to the lever P (ride Fig. 5)'. The lower end of the stem Q rests upon` .a

familiar form of diaphragm R .which is mounted within the diaphragm casing v1'() in device the parts are mounted .as shown, viz., with the diaphragm chaml er projecting below. the

floor of the car aid in an ex nosed position and with the valve casing pre `erably mounted above the .f lo or of the car, although 4neither of these points is essential. ragm c amber, said casing being pref- With the apparatuses so constructed,ithe' operation of my de vice will be as follows:

Ifthe device is applied to a car, the 4pressure in the train pipel may be as high'as,

It will be seen that the pressure.l ot th(-l steam Will tend to torce the ralrc upwardly and the collar H will carry the pacliing rinnor washer J with it until the washer is eurely seated against the under side ot the i. cap I, so that the steam pressure will hold the packing ring tiglitiy iii position and will make a tight joint at this point.

The cold air will be forced through the radiating pipes oiit through the drppipc 8, into lthe chamber (l and. thence thi-ouali the discharge pipe 9, through the dirapliiagiii chamber 10 and out at the bottom oi' the diaphragn'i chamber. As soon as the steam fills the radiating pipes to such a degree that the vapor escaping through the diaphragm chamber 10 is of sufficiently high teinperature to expand the diaphragm lt, the expansion of the ldiaphragm R will lift the stein Q and by means of the lever P and stein (i will close` the alve F, thereby shutting oft the steam supply.

This, theoretically, will be the operation of the apparatus. As a mattei. of' practical experience it has been found that as soon as the temperature Within the diaphragm chamber begins to rise, the diaphragm will. start to expand and will begin to close the inlet 'valveP Iii View of the tact that a con stant condensation is gio* 'i within tl?. ra-diiitii'ig;u system and ci: j pipes1r partial closing ot tre will rend to lessen the teinpeifajturc wyiiin the rai. ating pipes and. their f -ncfjtioi and conse qiiently the point will si the an'ioint oi steam a iti'eil through the inlet valve will be siiiiicieiit to keep 'the tcinperature in the diaphragm chamber at. a, point Where the diaj'ihragin. njill expand liiist enough to hold the inlet valve at that point.

As previously noted, when the thermostat R is Wholly or partially contracted, the pre-svention shown in lthe drawings, the Weight ot' the stem 5l su'ticieiit o at all times open the i'alve by .the actual gravity when thel thermostat is contracted, regardless ot whether or not steam is being supplied to the system. The spring L serves, incidiitally, as an additional positiif'e valve opening device7 und when the syste-in is bein y supplied with steam7 the pressure of the iiitioW- ing steam will be ell'eetire to open the valve independent of the spring L and the stem Q.

Among the aiflrantages by Way ot' sim plicity economy in installation and in inaiiitenance, safety and etfectiveness. which are incident to the above-described cariheating system, I note the following:

First. The system. is easily applied to a car without cutting sills or tioor joists.

Second. By using steam at low .pressure within the radiating system.y it is not necessary for the india-tors r return bends and fittiiigs to withstand the high train-pipe pres' siii-e, as with the direct steam heating tems non in use, and, therefore7 iniicli lighter radiators and fittings may be used` Third. There being no sudden filling of the radiating system with train-pipe steam at high pressure and high temperature, there is no sudden expansion of thc lattinge and consequent liability to damage and leakage.

Fourth. My system automatically distrib iites a substantially equal supply of steam to all cars in the train, since the high-pressure steam in the train-pipe, being checked in its flow into the radiating system otleach car, will proi'iiptly fill the train-pipe'and will then flow evenly' into all the cars lon the train. l A

Fifth. My system automatically maintains an even temperature in all the radius on the train 'it all times.

l: The es; insures sensitive and quick action' ot thei'inostat'in a. manner familiar in the mth. fcca use oit' the even temperature niaintii the amount of radiating sur face necessary to be installed in a car may be niore aci'iiirately deteriiiined.

Flight. All of the cars inthe train will be heated at substantially the saine time, insteadv of sucessiifely, as with present systems.

Ninth There are but two valves,v t0-Wit, one `feed valve for each side of the car, tobe installed and to be manually operated, as against foinsiich valves in other systems.

Tenth. There are no drip-valves .to be in stalled or to be manually operated, thereby eliminating the expense of installatiom'the cost ot maintenance and the element ofaincertainty which is inherent in every device which iniist be operated 4by hand.

Eleventh, lVheii the' train is put out of service there are n o Valves to be operated to insure the drainage of the pipes of the heating system, :is the system open and iinobf .nal exposure of the therstructed vfrom end to end and invariably au toinatically and quickly drains itself. Twelfth. No possibility of freezing.

Thirteenth. No cost for maintenance. li`onrtee`nth. No over-heating of the cars; and

Fifteenth. An economical use ot' thcsteam,

thereby avoidintgr waste of steam and, incidental thereto, avoiding expense and iight- `ening the load upon t-he locomotive.

I claim: V

1. The combil'iation `with a car, of a radiator therein, constantly open to the atmosphere, means for snppiying steam thereto at a substantial pressure, an admission valve for said radiator arranged to be closed against supply pipe pressure, a thermostat iat the discharge end of said radiator, op

erative connections between said thermostat and said valve colnprislng a rod adapted to niostat to close said valve and to he actuated be actuated by the expansion of said then.

by gravity in a direction to open said valve 'upon the contraction of said thermostat.

`2. The combination with a. car, of a radiator therein constant [y open to the atmosphere., an admission va ive for said radiator, a` thermostat at the-dis1 :barge end of Said radiator, ope 'ative connections rbetween said n thermostat and said valve, said connections comprising a rod adapted to be actuated by the expansion `of said thermostat to close said valve and to be actuated by gravity in a direction to open said valve upon the con traction of said thermostat, and meansv constantly tending to actnate said'strnctnre in a` direction to open said valve.
