AAppnmioninea .Tune 23,

This invention relates particularly to apparat-us for condensing steam exhausted from zii-,turbine or engine employedto drive a lo-y comotive or a railway car.

f Among the salient objects of the invention are to provide improved means for supplying air tothe radiators in which the steam is con# Y densed, and to provide Vthermostatically-con trolled means for varying the supply of air radiators.

By way of example, the car is shown as provided with a steam turbine 1` which supplies power for driving the car. Theexhaust steam may be conducted from the turbine to the condensing apparatus by any, preferred arrangement of conduitsand pipes. Herein we have shown two main conduits 2 extending from the turbine to 'two' conduits 3 extending longitudinally of the .y car below and near the vertical plane ofthe side walls. In each of the conduits 3 is a spray pipe 3a by means of which water is sprayed upon the steam to promote condensation. Each of the conduits 3 is connected by means ofa suitable number of pipes 4 to a series of radiators 5 forming the sides of the clearstory 6 of the car. Y

The radiators 5 may be of any preferred or well-known character. lVe have herein shown a form of construction comprising a top header 7, a bottom header 8, anda riser 9 at one end of the radiator, the upper end of said riser being connected tothe header 7. The pipe 4 discharges steam into the lower portion of the riser 9, as indicated by arrows in Fig. 4. A. spray pipe 10 extends 1926. 'serial 110,117,912.

longitudinally of and within theto'p header 7 andis provided with `jet openings whereby water is sprinkled'upon the steam contained in the radiator. The'spray 'water and the water of condensation `is drained from the bottom headerjS through a pipe'11 which extendsrto a sump 12* (Fig. l), whence4 it is i withdrawn `by means of a pump 12?l as required for the gen-eration of steam and for supplying water to thespray'pipes 3a and 10. 13 are drain pipes connecting the-conduits 3 with the sump 12. p y

`The condensate' pump- 12a` maybe a so called wet vacuum pump which serves to withdraw water andanyair contained in the system', but ifdesired aseparate airl pump or air ejectorinay be used.

Means'is provided for drawing air through the radiators 5', saidmeans being herein.

shown las comprisingan -exhauster located between eachpair of radiators arranged at oppositesides of the ClearStOry. In the drawings, the numeral "14 denotes an exhauster unit of known construction comprisingav fanv 14a arrangedto revolve in a horizontal plane and to discharge airl upwardly. w The series of exhausters 14 may be driven in any preferred manner. Herein wehave indicated that the exhausters are'driven from` a shaft lextending' longitudinally of "ande within the clearstory 6. The shaft 15 may be driven fronr'any suitable source, as,'for example, anfauxiliary turbine-"driven by a portion of the exhaust from themain turbine' 1, as explained in our application Serial No." A Y 62,062, filed October 12, 1925. WhenV thus driven, the4 exhaust fans are operated ata speed proportionatefto the quantity lof ex-V haust steam to be condensed. y y f Y Weather conditions or' Vother factors may make it `desirable to.l control the supply of air,

`to the radiators 5. Ve thereforeprovide for each radiatora seriesof'shutters 16 arrangedv at the outer sideof the radiator, each shutter beingvpivoted at 17 land arranged to swing into and out of a position which substantiallyl prevents the lentrance'o'f air throughl the radiator.: Any. desired means may be provided for uautomatically*moving the 'shutters 16 in accordance with changes in temperature...

of the water in the lower header 8. VI-Ierein We have indicated a cylinder 18 (Fig. 3) containing a piston 19 which is connectedby means of a rod 20 and linkage 21 to the shutters 16. A coiled expansive spring 22 tends to move thev piston 1.9 downwardly Y. to Aclose the shutter. Thespace within the cylinder 18 below the piston`19 is connected by meansv of a tube 23 to a closed container 24 located withinthe lower header 8,' said container,-the tube 23 and the space-within the 'cylinder'lS below the piston 19 being'illed with a.fluid,

the expansion and contraction of which as the temperature of theeondensatezrhanges resulting in corresponding movement of the piston 19.1and :hence of the shutters 16.

The location of the 'fans-between the radi-ators 5 and. discharging directly tor the atmosphere .isadvantageous in that there is no back pressure onthe' fans except that ofthe atmosphere. Moreover, when. theshutters 16A are in closedfor,nearly'clos'edposition, there is .littleor no airfiowing-through thera-diator's, and the. load- 'on the; fans is correspondingly light, with consequentsaving in power.
