STEAM-HEATING APPARATUS.

Specification of Letters Patent.

To all whom t may concern:

Be it known that l, EDWARD E. GOLD, a citizen of the United States ot America, residing in the borough of Manhattan, city, county, and State ot New York, have invented certain new and useful Improvements in Steam-Heating Apparatus, ot' which the following is a specication.

ln my patent for an improvement in a thermostatic mechanism, No.'1,077,224, l have described a steam heat-ing system tor railway cars of the interchangeable type, that is to say, which may be arranged to work automatically as a pressure system admitting steam to therradiators at the pressure Ot the train pipe or other source of steam under pressure, or as a vapor system having the steam in the radiators at approximately atmospheric pressure. ln my Patent No. 1,087,164, I have illustrated an apparatus tor use in a steam heatingv system accomplishing the same result. The present ap plication is an improvement in a thermostatic controllingor regulating apparatus for use in an interchangeable heating sys! tem.

The present invention involves the use of a thermostat which is exposed to the temperature of the discharge trom the steam heating system and is movable in position so as to control either an inlet valve, whereupon the system will operate as a vapor sys-A tem at substantially atmospheric pressure; or, in its other adjustment, will operate to control an outlet valve so that the system shall operate as a pressure system, and, in

an intermediate position, will enable both or' the valves to be opened so as to operate as a blow-oit.

rlhis invention is applicable to direct or indirect radiating systems, and the term radiator is applied to the steam pipes whether their heat is radiated directly into the atmosphere to be warmed or through the intermediation ot a body ot water. The admission and exhaust valves-may be norJ mally either open or shut `and may assume their normal positions under the influence ott steam pressure or a spring or weight. Y

In the accompanying drawings l, have illustrated the most desirable form of constructing my invention now known to me.

ln the said drawings,- Y Figure l is a perspective view of the principal parts of the system applied to the heating ot' railway cars;

Fig. 2 is a horizontal section through the thermostatic device and adjacent parts, the system being adjusted in full linesas a vapor system and showing in dotted lines, the adjustment as a pressure system; Fig. 3 is a similar view, the system being adjusted as a blow-orf 5 Fig. l is a plan view of an adjusting handle set in the floor ot the car;

Fig. 5 is a side view of the thermostatic apparatus the cover ot the casing being removed; a

F ig. 6 is a detail view of part ot the thermostatic casing illustrating the means for shifting the same.

Ny invention is illustrated in connection with a railway steam heating system hav-V ing a train pipe A which carriesthe supply of steam to the various cars. rlhis is Vprovided beneath the loor B ot each car with a pair of branches C, one running to each side of the car and each connected .by a vertical branch D passing through the licor ot' the car and a horizontal branch E with the radiator l?. The hand-operated stop valvel G is arranged within the car tor use when the supply or" steam is to be cut 0E entirely from the radiator. v Y

ln the horizontal branch C lbelow the iioor of the car is an automatic admission valve indicated as a whole by the letter H. The discharged steam and water ot condensation are led troni the radiator through the in clined branch K within the car, the vertical branch L passing through the Hoor or the car and theinclined branch beneath the car.

A. thermostat J is located in a position to be exposed to the temperature ot the discharged steam or water of condensation from the radiator. This thermostat Vis preferably located within a casing` N, into which pass the discharged steam and water of conm densation from the radiator. llhis thermo` ratentea apr. so, rare..A

contains a small euantitmY o relatie lluid VVhigh so that, if the thermostat is adjusted to the full line position of Fig. 2 a. temperature 'oli the discharge :trein ator is sutiiciently great, the i caused to expand, thereby closing' the inlet *the valve diss*` t seat and shut the system will. elet the admI t the temperature dotted iet valve Wil. ene spring P am, n pipe pressure, or such pressure as mau. be desired, L J-lwg nflni u *iE/dn (rn f1 l; rl' ln W3 '51' Tn to eclater. lacthe .iscaaic i; .L l v l A: 5 e the radiator is hot enough, the outlet :faire i@ upV prestor until the t nmerature to a point Where the is contracted,

Whe i' it is desired that both the islet and VVoutlet valves should be open to lpermit blowing-off of the pipes, the thermostat is capable of adjustment to the position illustrated in Fio. 3, Where both the inlet and outlet valvesY are open and steam may freely pass through the pipes and blos/the condensed Water out oi the same. Y f

The thermostat is Villustrated as being mounted in acarrier or cage R, wherein it is held by short arms r (Fig. 5) permittino the cage to be operi at each side so that the thermostat will be freely exposed 'to the ltemperature of the Ydischarge from the radiator. The thermostat is suitably mounted in the casin N so as to be ca able of beine P e turned therein. As illustrated, such mounting 1s by mea-ns of a pivot upon Whio thermostat 1s journaled and which is supported in the casinfr. Desirable means for shifting the thermostat, as illustrated, comprise a stein T Which projects up through the ioor oi' the car and there carries au iudicatiug handle t which indicates upofi a dial U Whether the thermostat is adjusted to Vaporf Blow-olf, or Preesure."' iii' the lower end of the'stem T is a lever V which has a pin and slot connection o o1 with the cage for turning the. saine.

it will be perceived that the illustrated means for shifting the thermostat provide- :i loch for holdingthe same in adjusted position. This may be seen by an examination of Fig. 2, wherein the thermostat is illutrated in full lines as being` adjusted to coutrol the inlet Valve. The reaction oi the thermostat is exerted through the cage in a straight line through the slot, piu and lever V to the stein T, and this xsaine result ifY accomplished when the thermostat is adjusted to con he discharge Y e, as il..

la, has a Valve disk O' caried by a and normally held epe:V b" a spring -r of operating the 1s o au,

rllhe discharge valve Q is illustrated as being carried by the cade l, and by this method of construction, it achieves the dou-- ble advantage of acting as a liXed abutment to receive Jhe thrust of the thermoftat when adjusted in position to operate the inlet valve, as Well as serving to close the discharge opening. lVhen it is adjusted to the position. to close the discharbe opening, it normally held oir of its seat by a spring Q1 and, Whe closed, it is pressed against a valve seat A plug Z1 is niovably secured in the casing in a position opposite the discharge opening aud enables the seu t Q2 to be renewed, if desired.

them to give to open their respective valves as `the thermostat contracts, and both are provided with flanges engaging againstshoulders in the cage which prevent their passing out of the cage and enable them to number of arms r to hold the thermostat in' place. Four of such arms are illustrated at each side and at the inner ends of these arms the abutments Q X are carried. The stem T is provided with two arms V whichl are held on squared portions ot the stem, as illustrated in Fig. 3, and these arms engage opposite sides of the cage, as illustrated in Fig. 6, for the purpose of adjusting the same in position.

When the system has been operated under pressure and the heat is out ott bythe stop valve, condensation of the steam in the pipes causes a vacuum, which draws up or holds up lwater in the pipe to a certain extent and introduces a liability to freezing. To prevent this, T prefer to use a gravity operated trap of the style shown in my Patent No. 522,253. The arrangement of sucha trap is shown in Fig. 2, where the trap is lettered generally G1. Its operation is fully described in my Patent No. 1,087,164 and need not here be repeated. Iii' desired, this apparatus might be converted into a simple vapor system. or into a simple pressure system, by means such as are illustrated or described in my Patent No. 1,087,164l with reference to the system there shown.

In theloperation of my impro-ved device, let it be assumed that the system is desired to act as avapor system, in which case the stem T, by means of the handle t, will be turned so that the indicator will point as illustrated in Fig. 4, whereupon the cage and thermostat will be in the position of Fig. 2. The inlet valve O, however, lwill be held open bythe spring P permitting the When the radiating pipes have become suiliciently warm the temperature of the discharge from the pipe M expands the liquid in the vthermostatic vessel J and causes the said vessel to swell up, which will press the abutment Q to its seat in the cage, whereupon the said abutment will serve as a reaction element transmitting the thrust of the thermostat through the cage and arm V to the stem T and so to the casing and thereupon will exert pressure againstthe abutment X and Cause the same to close the inletv valve O. This valve will remain closed until the temperature of the discharge from the pipes causes the temperature within'the casing N to drop to a point where the .thermostat contracts. rThereupon the spring P will open the valve U and the foregoing operation will be repeated 1f it nowvbe desired to secure ay greater-supply of heat from theV radiating pipes, the handle 1f may be turned to Pressure 'and this will give the stem T a quarter turn and shift the cage and thermostat to the position illustrated in dotted lines in Fig. 2. Thereupon, when the temperature of the escaping steamhas heated the thermostat sufficiently to expand the same, it will press the abutment X to its seat inthe cage, which-will thenserve as a reaction element whereby the `pressure of the thermostat is transmitted through the pin and slot o 'v1 to the stem T' and so to the casing. The continued expansion of the thermostat will press the abutment Q toward the seat Q2, compressing the spring Q1, until the same completely closes the outlet from the radiator. It will remain in this position until they temperature within the casing, under the influence of the Ventilating 'plate N2 has dropped sufliciently t0 contract the thermostat, whereupon the spring Q1` will cause the valve Q to open, releasing the water of Fig. 3 and the inlet Valve O vwill be opened by the spring P and likewise the outlet valve will then be opened and steam may freely circulate through the pipes.
