-This invention relates .to. motor driven railroadcars and more particularly to cooling systems for themotors employed in operating such cars; l

As illustrated, the invention is shown in connectionwith a inotor driven railroad car 10 provided with a motor" 11, only part of" which is shown in Fig. 1. A storage tanlrl2v s connected to the water jackets. (not v cylinders by suitable shown) ot the; motor piping and a pump (not shown) of; any desired formis provided for forcing the water fromthe motor cylinders through vertically extending pipes 1-3 to a relatively small distributing tank- 14 positioned above the motor. The distributing chamber is connected by pipin'glti to headers 16 extending long} 'tudinally along each sideof the car body beneath the edges of the 'car. roof 17 and eachi header is secured-in. place by straps 18 bolted to upright extensions 19 jofthe ,car body.. A pluralityof separateradiator units are supported .in inclined positions above and transversely" to'the car roof. and the lower end of'eachun'it has a header 20 con-- nected inpa'rallelor 'in'shunt by piping 21 extending loosely through openings 22 in the car roof to headers 16. Each'branch pipe 21 isf provided' with a manually operated.

valve 23 for opening-and: closing "the associated, radiator inlet and a hose connection 24 "is provided. for connecting each pipe 21 with the inlet25of-the associated radiator unit, Mechanism such fo r. example,' as a 'Petticoat-26jn10untedon the pipe 2'1is proradiator supporting bracket 27. "having an opening through which a pin 28 secured to and extending downwardly from the laCllfl' itor header is received, and a spiral spring 29 is interposed on the pin 28 between the bracket and the header so as to provide a cushion support for absorbing; any vibrations of the bracket. As shown, the S bracket 27 is rigidly secured to the roof 1'? of the car and has a hole or slot cut through the bent or face portion of its extending end. The spiral spring 29, as shown, preferably consists of two sections one interposed above the face portion of the bracket 27, the other interposed below the face portion thereof. The fluid transmitting radiator tubes 30, diagrammatically shown in Figs. 2 and 4, are inclined upwardly from a tube sheet 31 in the inlet header to a tube sheet 32 in the radiator outlet header 33 which is connected by piping 34 with a return header 35 extending longitudinally along the center ofthe car and supported beneath the I: roof by supporting straps 36 bolted to the car lines 37. 'Theradiator outlet headers 33 of each unit are connected in parallel with the return header 35 through the p1ping 34. The piping connecting the outlet headers of the various radiator units with the collecting or return header 35 extend through openings 38 in the car roof which are surrounded by upwardlyextending the system.

flanges 39 cooperating with flanged plates or petticoats 4O bolted to the piping 34 so as to cover the openings 38 above the surround- 'ing flanges 39 to prevent the entrance of rain or the like 1nto the car.

The outlet header of each radiator unit is provided with a baffle 41, see Fig. 4, which is spaced from the tube ends and extends from the bottom of the header to a position adjacent the top thereof. Such a brittle insures the complete filling of each i radiator unit and the flow of water through all the tubes thereof during operation of The return header 35 is connected with a return pipe 42 for conveying watertherefrom back to the storage tank 12.

' bypass 43 having a valve 44 is provided for permitting the water to flow directly from the distributing or mixing chamber 14 through the piping 15 and backto the storage tank 12 without passing through the various radiator units when it is desired to rapidly warm the motor in starting in cold weather, and this by-pass is conveniently operated-by opening or closing the controlling valve 44. g ve atig the ,w trii i taken fromthe storagetank by the circulating pump and From the distributing tank the hot water flows to the longitudinally extending headers 16 communicating with the various radiator units positioned above the car roof. From the header the water flows upwardly through the various piping connections 21 to;the associated radiator units where it is cooled and from which it returns through the pipes 34 to the return header 35 extending longitudinally of the car and connected to each of the radiator units. turned to the storage tank through the return pipe 42. It will be apparent that any number of radiator units can be cut out of operation independently of any other units merely by closing the associated inlet valves 23. It will also be apparent that opening of the by-pass valve 44 permits the circulating water to bypass all of the radiator units and return directlyto the storage tank from the distributing chamber 14 so as to permit rapid warming of the motor in coldweather. 1

One advantage of the present system is the fact that it is completely self-draining. The inclination of the radiator units and piping connections is obviously such, see Fig. 1,-that when the motor is stopped and the valve 44 open the water .will be drained by gravity from all thevarious radiator units and connecting pipes back to the storage tank 12.

The latter is so arranged that when the syspresent invention of such arrangement as to be capable of being employed in using either steam or water as a cooling agent, and the arrangement is such that the system can be adapted for one or the other of such cooling agents merely by the operation of a single valve. As illustrated, the water jackets of the engine are connected by piping 13? to a control valve located within the mixing or distribution chamber 50 having a port 51 connected to the piping 13. A second port 52 is connected by suitable piping 53 with the longitudinally extending header 16 at each side of the car. Athirdport 53 is connected by piping 55 to the storagetank 12 and a fourth port 56 is connected to the central w header 35 by piping 57.

The cool water collected in the header flows through the piping 57, valve ports 53 and 56 and piping 55 to the storage tank.

When steam is employed, the valve plug 1 58 is positioned as shown in Fig.8. The heated'steam rises through-the piping 13. and flows through ports 51 and56 of the valve to piping 57,-whence it reaches the radiators ly through each radiator unit and collects in through the header35 and associated radiator.
