Y and concealed by the si e walls lof the railwaly car. v

n order-to improve the appearance of the car, economize on space,

and provide greater eiciency 1n the heating system, it is desirable that the radiating system mounted within the hollow walls of the car, these walls, rather than in the open body of the car as in systems heretofore in use. The ordinary side wall construction of passenger cars comprises a plurality 'of spaced apart vertical posts which carry the inner and outer walls., that is the inner lining wall and the outer car sheathing. Separated spaces are thus pro vided between' the pairs of posts and the inprovide ainplev room for the radiating coils or pipes and the reiiecting shields and insulation as sociated therewith Howevery 'it is desirahle that continuous pipe coils ent/ending longitudinally of the car he used, and the ordinary form of vertical posts used in the car wall construction stand in the way oi According to the present invention, the lower portions ot these posts are cut away on provide a shallow passage tudinally of the car near the door through which the radiating pipes may pass.. Pret erably the posts are dattened out at their lower ends so as tact with the inner side wall, the reduced extending longitheir inner sides 4so as to to stand hach out of con-- thickness of the post being compensated tor' hy an increase sary strength is not saciiced. The longitudnally extending pipes or coils are supported directly on the inner faces of these flattened portionspof the post hy ineens of suitable clamps or brackets.. ln the spaces between the osts, radiating hns may he mounted on t e pipes so as to increase the radiating surface, and reflecting shields are ositioned behind the coils so as to preveiit iieat losses and coo crate with inlet and outlet passages in the inner sidewall of the car in breadth so lthat the neces'-V i et the t0 coi VThe principal object of this invention is to'provide an improved concealed radiating system for railway cars, such as is briefly described hereinabove and is disclosed more in detail in the description to follow.

Another object is to provide an improved form of concealed radlator for use in the Erovide a circulation around the heating s walls of railway cars.-

Another ob]ect is to provide aniin'proved form of side wall construction '".Eor railway cars to permit the use of concealed radiating systems therein. A y

Other objects and advantages ot this inrention will he more apparent from the following detailed description ot one approved form of heating system. embodying the principles. oi this invention." y

portion otV one 'side wall of the car isy indicated at A, and a portion oi the door at E. The side wall coin rises a plurality i tudiot vertical posts G space apart l nelly ot the car, and the inner w and the outer wall E carried hy these posts C. `indows l" are provided tween the upper portions of the posts C., or between certain airsV of posts, leaving spaces G heneath t e several windows which are. se arated from one another a 1|@ inclosed by th adjacent air of (posts C and the inner and outer wa s D an E. It'is in these several wall s aces G that the major rtions of the radiating system is positions The posts C may take a variety of forms,

per portions of the posts the heating coils as indicated by the ar-v rows in Fig'.- 3. If

, channel but are referably constructed of a pair of Ibeams 1 and 2 connected by suitable covering plates such as 3 and 4. In their normal form, as exem lified in the upin the present disclosure, these posts are relatively narrow (in the-direction lon itudinally of the car) and are of suiicient e th to extend between the inner and outer wa ls D and E which the posts contact with and support. According to the present invention, the lower portions of these posts are attened outwardly on their inner sides, that is made of less depth and greater width (as shown at 5 in Flgs. 3 and 4), so as to leave a-shallow Vertical space extending longitudinall of the car between the front faces of t e posts and the inner wall D, this space being suiilciently deep to accommodate the radiating pipes 6.

which extend continuousl throughout a considerable portion of the length of the car. These pipes 6 are mounted against and secured to the front faces of the flattened portions 5 of the posts by any suitable means such as the straps or brackets 7 and bolts 8 illustrated in the drawin s.

A plurality of radiating fins 9 may be secured on the pipes 6, in the wall spaces G between the posts, in order to vincrease the radiating surface. A reflecting shield 10 is positioned in each wall s ace G behind the radiating coils, a lowerhorizontal portion 11 of this shield extending beneath the coils and bein anchored at 12 to the lower ortion of t e inner wall D adjacent the dbox B, and the upper portion of the shield curving inwardlyIand upwardly at 13 and being anchored at 14 to the inner wall D above the radiators: wall D in front of one of these shields 10 is provided with an inlet` passage or opening 15 beneath the radiator, and' an outlet passage or opening 16 above the 'radiator so `as to permit a free circulation of air from the interior of the car, around and between necessary, the lower ortlon of the inner wardly as indicated at 17 to-provide suiheating coils for Y currents. Preferably,vtl1`e upper outlet opening 16 will be covered by a suitablefgrill as 1n 1 cient space between the inner wall and the the passageA of the air cated at 18, so as to partially close this openingI without interfering with the circu lation of air therethrough. Suitable insulation, as indicated at 19, may be provided behind and around the shields 10, as may be found necessary or desirable in order to protect the walls of the car and prevent heat losses.

Although this radiating system might be utilized. with different types ofheating systems, it is particularly designed for use in a vapor car heating system of well known Each portion of the inner wall D may be bowe inample size to satisfy any requirements can easily be installed without upper longitudinally extending radiating pipe 6, an the several pipes'6 are successively connected in pairs by couplings 26 at the ends thereof so as'to form one continuous pipe coil, the steam and condensate flowing from the lowermost radiating pi e through connecting pi e 27 back to the distributmg valve 24 and) 28 to the vapor regulator, whereby the steam supply is automaticall controlled in well known manner. The distributing valve 24 may be controlled by hand or automatically by thermostats as is well known in the art.

In the modified form of radiating system shown in Fig. 1, the radiating pipes are connected in two series' so as to form two separate radiating coils, the two upper pipes 29 and 30 being connected at the end remote from the distributing valves by a coupling 3l, and the lower pipes 32 and 33 bein similarly connected-by a coupling 34. 1g pair of separate distributing

valves

24 and 24 are used, the steam supply being directed to the first distributing valve 24 and thence through the pipes 29 and 30 of the first heatving coil and back to the valve 24 as in the first described system shown in Fig. 2. The steam returned from the firsti coil flows throu h connecting pipe 35 to the second distri uting valve 24 and thence through the second heating coil from which it' is returned by .pipe 33 to the valve 24 and thence through pipe 28 lback to the vapor regulator. By proper control of the distributing valves, one of the heating coils may be cut out of service when a single coil is suicient to satisfy the heatingrequirements. y

Preferably there will be at least one of these radiatin systems in each side wall of the car, an if desired two or more such systems can be arranged end to end in one side wall, in case it becomes undesirable or impractical to further the heating coils in any one system.

It will n ow be 'apparent that the only change that is necessary in the ordinary construction of ther side wall of the car, is the changed conformation of the lower ortion of the posts C, andthe provision of t e necessary circulation passages in the inner wall D. t the same time,

maximum heating materially encroaching on the clear provided .1n the interior of the car.

thence through pipe extend the length of radiating coils of 20 radiating ipe coi s neiaooa I t pe of installation is much more sightly t an those in which the pipe coils are mounted directly lin the car compartment, and the comfort of the passengers is increased and a more eicient circulation of the heated air is provided. j We claim:
