1 Claim.

to permit the radiator units to be conveniently and readily removable independently of each other notwithstanding that they are mounted to receive a common current of cooling air.

Other objects and advantages will be more apparent to those skilled in the artofrom the fol lowing description of the accompanying drawings in which:

Fig. 1 is a side elevation of an internal combustion engine locomotive preferably of the Diesel engine type with parts of the hood re moved to show the general location of my improved radiator system;

Fig. 2 is a fragmentary perspective of my improved radiators and certain associated air control elements;

Fig. 3 is a partial horizontal sectional view taken substantially on the lines 33 of Fig. 1; and

Fig. 4 is a transverse section taken on the line 4-4 of Fig. 3.

In the particular embodiment of the invention disclosed herein, I have shown a locomotive having a compartment generally indicated at l for an engine, such as a Diesel engine, to drive preferably through an electric generator and motors, trucks 2 and 3 while a cooling system compartment is generally indicated at 4. This compartment contains a set of vertical oil cooling radiator 5 behind which are supported a series of upper and lower groups of water cooling radiator sections 6 and l. The upper group 6 is secured to an upper .tank 8 while the lower ends are secured to an intermediate tank 9 and the lower group'of radiators l are secured to the intermediate tank 9 and to a lower tank generally indicated at W, Fig. 2. Each of the radiators 6 and l is subdivided into separate vertical sections and held to the respective tanks by studs and nuts I l positioned on the rear side of the headers, this being accomplished by providing each of the radiator sections with generally T-shaped top and bottom headers I2 and Ill. The T-stems or header flanges project upwardly and downwardly from the radiator sections thereby to provide right angled recesses to receive the stationary tanks 8, 9 and 10. The front face of the tanks and radiator sections 6 and 1 will thus be flush with each other and be brought into close compact relation to .the oil radiator sections 5. The upper and lower tanks 8 and I'll are preferably of L shape whose depth is substantially equal to the depth of the radiator sections *6 while the intermediate tank 9, is preferably only of rectangular shape as shown. It will, of course, be understood that the radiator passages and air cooling fins therefor of the radiator sections are of any usual and well-known form whereby water may flow through the radiator passages and communicate with the tanks 8, 9 and 10 through usual and suitable openings in the T-shaped headers l2 and I3. Details of these openings do not constitute a part of my present invention and hence need not be described. One of the'principal features of th present invention is in supporting the cooling radiators 5 at the front of the tank structure and of mounting the engine water cooling radiator sections 6 and l behind the oil radiator, together with fastening these radiator sections 6 and I from the rear side of the tank whereby upon removal of the nuts H the radiator sections 6 and I may be bodily rearwardly removed from the tanks without in any way disturbing the oil radiators 5 or of requiring any dismantling of the usual adjustable air controlling louver system It placed immediately in front of the radiator apparatus. This radiator arrangement also has a desirable functional cooperation with a usual air duct I5 which is not only located behind the radiators but completely encloses the four sides leading therefrom. A back plate I6 is provided with a fan opening I! for connection to a suitable blower casing I8, Fig. 3, having a blower rotor IS. A pair of lateral openings 20, one on each side wall of duct l 5, are normally closed by covers A and B, Fig. 3, but for purposes of clarity these covers are omitted from the other figures. Notwithstanding that the back plate l6 of air duct l5 and the blower mechanism are rigidly mounted in a preferably permanent position, yet the radiator sections 6 and I may be readily removed by first taking on door A or B and also removing the upper or lower inclined walls 16a or l6b of the duct l5, after which nuts I I may be removed whereupon the radiator section may be pulled back over the studs and then merely moved laterally through one of the openings 20. The openings are of suflicient depth to accommodate the entire length of the radiator sections as is shown in dotted lines at 2|, Fig. 4, and are covered when not used. The inclined walls 16a and IE1) are suitably removably secured to the remainder of the duct structure by bolts or other suitable means.

From the foregoing disclosure, it is seen that I have provided an extremely simple, compact and economical arrangement whereby a plurality of liquid cooling radiator sections may be supported in extremely close juxtaposition one behind the other and yet either set of radiator sections may be conveniently and expeditiously removed independently of each other without requiring any unnecessary removal of the other radiator sections or dismantling of any auxiliary or accessory elements. This arrangement is particularly effective in a combination such as disclosed herein where a single air blower and passage causes a common circulation of cooling air over both sets of radiators. This problem is further complicated by the presence of the common air duct 15 and the fixed relationship of the blower. v

It will of course be understood that various changes in details of construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of the invention as set forth in the appended claim.

I claim:

The combination in a locomotive of the type having a water cooled internal combustion engine comprising, a set of tanks, a radiator located in front of said tanks, engine water cooling radiators located at the rear of said front radiator, a fan located rearwardly of said water radiators for circulating a common stream of air over both of said front and rear radiators, means for connecting and supporting the water cooling radiators by said tanks from the rear side thereof whereby said water cooling radiators may be disconnected from said tanks and removed therefrom directly from the rear side thereof while the front radiator remains in position, an air duct extending rearwardly from said tanks and forming a complete enclosure terminating in a 4 fan opening in which the fan is disposed whereby the common stream of air is guided and directed over both the front and rear radiators, and said duct having a side opening whereby a water cooling radiator section when removed rearwardly from the tanks is then movable laterally through said side opening.
