To all whom it may concern:

Be it known that I, citizen of the United States, and a resident of the city of Chicago, and State of Illinois, have invented certain new and useful Improvements in Heatingiping of passenger cars. 20

V mg the various objects of my invention is t eprovision of a device which may bc-rendily attached to a standard type of ear heating system arranged to be operated under supply-pipe pressure, whereby, with a minimum disturbance of existing installations, the system may be made operative at will at either supply-pipe pressure or at a lower pressure, such as what has come to beknown as the vapor system. These.and such other objects as may hereafter appear are attained by my present invention, a convenient embodiment of which is shown in the I accompanyin drawings. in which- Figure l s lows. in elevation, a standard automatic steam tra' of a high-pressure heating system fitte with an attaclnnent wherebythe supply 110 said system may be automatically controlled by the temperature of the heating medium at a point adjacent to or relatively near the outlet'ot the steam. Fig. 2 is a view, partially in vertical section, of Fig. 1. Fig. 3 is a cross-section on the line 3-3 of Fig. 1, lookin in the direction indicated by the arrows. ig. t is a section on the linc 44 of Fig. 1, looking in the direction indicated by the arrows. Fig. 5 is a detail elevation with certain parts in sectuin. Fig. (i is a sectional view on the line aft-6 of Fig. 3. looking in the direction of the arrows.

my Patent connecting with an outer around the casing or pipe In passenger cars which are heated by direct steam supply from the train-pipe, s. standard t'pe of automatic substantia K the same as the trap shown in 0. 752,219. Such a trap is inin which 1 is; the return or exhaust-p1 e leading from the radiating system into tiic valve-casing 2., which is provided with a valve-seat 3. The opening through this valve-seat is adapted to be automatically opened and closed by a valve 4 mounted on a valve-stein 5 and actuated by a thermostatic member, such. the flexible diaphragm 6, which is hollow and contains a, volatile fluid, and is mounted in a diaphragm-casing 7 from which the water of condensation and steam trap is.

vdicated in Fig. 2 of the present drawings,

cold air may escape through openin s 8.]

This diaphragm is provided with an a justiug stem 9 w ierehy the automatic action of the valve el may be properly adjusted. From the valve-seat 3 a casing or drip pipe 10, 10 extends downwardly, connecting with the diaphragm-casing 7. The action of this valve is familiar. admitted to the heating system the cold air, and any :iccun'iulation of water of conden \Vhen steam is primarily sation, is forced through the valve-seat 3,

the casing 10', 10 and the diaphragm-casing, 7 and out through the openings 8, the diaphragm 6 being cold and contracted. As the radiating pipes are filled with steam, the steam fills the return-pipe 1 and thence flows downwardly through the valve seat}, the

casin 1O, 10 into the diaphragin-chamber T an heating and expanding the diaphragm. 6 which, thereupon, lifts the valve-stem 5 and closes the valve l against the seat 3.- With around the diaphragm 6, thereby such valves it is also usual to provide the casing 2 with a blow-off valve, comprising a valve-scat 11 and a valve 12, provided with a valve-stem 13 and a hand-wheel ll. This blowbfi valve is normallyclosed and'leads around the valve seat 3 to a passage-way 15 ipe or casing. 16, which usually and prcfera wardly to a oint adiacent to'the top, of the diaphragm-c iamber 4. \Vith this construction, whenever the blow-ofl' valve is open the 1y extends downwater of condenstion, cold air and steam will flow; freely through the blow-o5 valve,

10, and against the automatic tra described such standard device diaphragnrcasing and-thence to theT- atreadily thaw and the parts contained therein, are below the floor of the car which, in Fig.2, is con-.

' veniently indicated at 17.

necessary tecut o 1 In attaching my resent device, it is merely a portion of the lower part of the blow-01f pipe 16 and to mountmy present attachment thereon and to then connect such attachment, with short pipes, to

the train-pipe or other source of sup ly of the heatin medium, and to the ra iating all 0 which connections can be made ow the floor of the car, and thus without other disturbance of the previous installation and, without entering the car, my invention maybe applied and the system may be converted into one which may be readily operated at will either under supply-pipe pressure or as a low-pressure or vapor system.

This result may be accomplished as followsz' Referring now to Fig. 8, 18 is a casit wi to viously described, has been cut I with the mg provided with an inlet-chamber 19 and a valve-chamber 20, which are separated from each other bya partition 21. This partition 21 is rovided with a valve-seat 22 adapted to be c osed by a valve 23,which may be guided in an suitable manner as for instance, within t e valve-seat 22, and a ni le 24, in which the valvesstem 25 exten s. e inlet-chamber 19 is connected with a source of an ly, such as the train-pipe, by a pipe 26, w 'the valve-chamber 20 connectswith the'radiating system by a pipe 45 27. .When the lower end-of the casing or pipe 16, of'the automatic steam trap re; ted h h away an the cas' 18 moun t ereon, t e assage-way tv l' e 'en the pipes 10 and Iiiill connect d Jay 28 in thedcaiing 18, sai passe -wa 1 se arate y suitartit lzns, from he inlet-chamber 19 and e valve-chamber 20. Consequently, still referring to Fig. 3, when steam, for'example, is turned on, it will enter the chamber 19 from the pipe 26, will pass through the valve 22 and the chamber 20, and thence through thepipe 27 to the radiator, whence I return (wide Fig. 2) through the pipe 1 to the casing 2. If, now, the blow-off va ve 12 is open, the returning steam will not only flow through the valve seat 3 into the casing '10 and thence to the diaphragmcasi flow t rough'the valve seat 11 and pipe 16 As ordi-. narily installed, all parts of such'steam v trap, but which wlll ordinaril except the upper part of pipes 10 and 6 'This' diaphragm stem 34. The. stem 33 isheld in one tion, as shown in eng es a rock-arm 6. -"T is rock-arm 36 is y'attached to a rock-shaft or stem 37,

the rock-arm 39 the thermostat "place between the 7 and to the atmosphere, but will also to .;-:*-1'- way 28' and thence downwardl I to theoutlet-chamber'29 (videe outlet-chamber 29 is contained a -casing 31, which is with o or, outlets 30 leadin gto th'e atmosp ere, or other discharge oint. Th'e diaphragm-c 31 containsa member 32, whic is preferably in the form of a diap m similar to the diaphra 6, y-be mean in a as shown iii the drawings. 32 is arra stem 33 and is provided with an adjust' P a spring 35 and vertical position,

I

turn, depend upon the relative effect of the tion when it reaches the chamber 29,.the'

action of the thermostat-32 will simply serve to throttle the valve 23't0 such an extent that there will be a suflicient inflow'of steam s ring 35 e5 (Fig. 3) and the 'valve 23 the action from the high-pressure supply-pipe to comcondensation which takes inlet-valve 23 and the dischargechamber 29. To prevent any'leakage of steam from the passage 28 directly to the atmosphere without passing through the pensate for the chamber 29, I provide a stnfling (Fig. 2). 1

It will readily understood that with my invention applied in the manner above -times except when there is an accumulation "of condense-water or cold air in the pipes,

and the return or exhaust steam will pass from the casing 2 into the casing 18, through the passage-way 28 to the chamber 29, where it Will actuate the thermostat controlling the steam inlet-valve 23. Consequently, the system may be economically operated as a lowpressure or vapor system, thereby insuring a the over-heatin of the car avoided, and the I maintenance of the desired temperature insured.

Inasmuch as this system openates as a vapor system when the blow-ofi' valve is open, it is'evident that there will be no pressure in the blow-off pipe; consequently there is no need for a tight joint between the blow-off pipe and the casiiig 18. This enables me to use a simple slip joint at this 1 point, so that the casing 18 may be turned on this joint to permit of the adjustment of the connecting pipes at an convenient. angle which the construction a nl fittings of any particular. car may require. So, also, the construction of the casing l 'is such that the ports to which the steam pipes are connected may be tapped in at. any one of several 'points, thus permitting of the ready adjustment of this casing 18 to a car already in service and in connection with the previously installed steam pipes, with a minimum of delay and expense.
