The present invention relates to rail car constructions and embodies, more specifically, an improved vroof construction for traction locomotives, the locomotive cooling units being conveniently embodied in the roof structure to provide effective cooling thereof, at the same time maintaining them in such position that they will not obstruct the convenient operation of the locomotive.

The present invention contemplates mounting the cooling units in the above manner, not only to effect the above results, but afford maximunr protection for the units'as well as simplicity ofthe locomotivefcooling y temv a I An object of the invention, therefore, is to provide animproved roof construction fortraction locomotives in which is embodie d the cooling units thereof. 7

A further object of the invention is to provide a roof constructionbf the above character in which a false roof is provided including the cooling units, sufficient space being maintainedbetween the false and'true roofs to insurethe necessary flowof cooling air through the units.

Further objects, not specifically enumer ated above, will be apparent as the invention is described in greater detail in connection 7 with" the accompanying drawings, wherein F gure 1 s a plan V ew, partly broken away, showing a locomotive roof constructed in accordance with thepresent invention.

F gureQ s a view 1n s de elevation, showing the roof construction of Figure 1.

Figure 3 is a View in end elevation show-' ing the foregoing roof construction.

Referring to the above drawings, wdesignates the sides of a locomotive cab provided with exhaust stacks b. In the present construction, three such stacks have been shown, but it will be readily apparent that this numcated at clpthe radiators including upper and lower headers 03 and respectively. Lower headers (Z are securely monnted upon the roof 0 to prevent relative movementbetween such portions ofthe radiators and the roof. These headers are adjacent the sides of the cab and the radiators thus eX- tend upwardly and inwardly to 'afl'ord the desired sloping as shown in Figure 3. The upper headers (Z are mounted upon expansion plates 6 which permit relative movement between the headers d and roof 0, thus providing for expansion of the radiators in operation.

About these radiators which are spaced upon either side of the roof and extend along the length thereof, a false roof fis mounted.

The false roof is formed with eaves f which between the adjacent edges of the sections sufiicient to receive the exhaust stacks and other cool ng mechanism, such as expansion tanks, etc. Within the false roof sections 7,

apertures f are formed, these apertures being of a size suflicient'to receive the radiator sections cl therein. The portions of the false roof 7 between adjacent radiators are mounted at their upper extremities upon expansion plates 6 which are independent of the expansion plates 6;

From the foregoing, it will be seen that the false roo-f construction directs the flow of cooling air through the radiator sections andprevents any flow in a vertical direction throughv the false roof without pass ng through such sections. The roof is of such vcharacter that it may be readily mounted and ClISIIlOHHlIQCl flQlD the cab, at the same etnneaffnltfihng adequate protection for the units andbeingof such character that it will withstandthe stresses and strains incident to p rati fthel em t e While the invention has been described with specific r ference to the accompanying drawings, it is not to be limited, save as defined in the appended claims.

l. A vehicle roof construction comprising 7 plurality of radiators, means to mount the radiators upon a permanent vehicle roof, a plurality of exhaust stacks carried by the roof, a false roof, apertures in the false roof to receive the radiators, means to secure the false roof to the stacks, means to secure portions of the false roof between the radiators to the permanent roof with provision for relative movement with respect thereto, and means to secure the false roof to the sides of the permanent roof.

5. A vehicle roof construction comprising a plurality of radiators, means to mount the radiators upon a permanent veh cle roof, a plu-ality of exhaust stackscarried by the roof, a false roof, apertures 1n the false roof to receive the radiators, means to secure the false roof to the stacks, means to secure portions of the false roof to the permanent roof with provision for relative movement with respect thereto, and means to secure the false roof to the sides of the permanent roof.

6. A vehicle roof construction comprising a plurality of radiators, means to mount the radiators upon a permanent vehicle roof, a plurality of exhaust stacks carried by the roof, a false roof, apertures in the fasc roof to receive the radiators, means to secure the false roof to the stacks, and means to secure the false roof to the sides of the permanent roof.
