The present invention relates to cooling systems for motor vehicles and embodies an improved construction which provides )greater cooling than is possible with cooling v h systems of the present type.

' Vln motor vehicle construction the problem of proyiding an adequ'ate radiating surface for the-Cooling system of the engine imposes a serious -limitation upon the conventional MI' designg Existing practice has mounted the radiator at the front of the vehicle and utilized an engine driven fan to induce a sufficient flow of cooling air through the radiator. lt is quite apparent that the limitations W upon constructions of this kind are considerable, and being unable to increase the size of the radiator, the quantity of .air drawn therethrough has been increased. ith increased demands upon individual units, it has been found that the above limitations present a serious factor in motor vehicle design and the resent invention has for an object theprovlsion of a cooling system, the physical limitations of the space occupied thereby being practically removed.

A further object of the invention is to provide an improved radiator construction having a fan or fans to induce a flow of cooling medium through the radiator regardless i stt of whether the vehicle is moving or at a standstill. J

lt is. a further object of the invention to providea radiator construction of the above character in which lcooling fans are provided to rotate 'in opposite directions, depending upon the direction of travel of the vehicle. i

Further objects will be apparent as the description proceeds and reference willnow be am had to the accompanying drawing, wherein: away, showing a preferred form of the'invention wherein7 the radiator is mounted upon the top of the vehicle and at the rear thereof. i I

Figure '2 is a side view, showingthe radiator construction of Figure 1. P? ffigure 3 is an end view of thev radiator shown in Figures 1 and '2.

Figure 4 is a rviring diagram showingthe 'W manner in which the fans are connected so Figiire 1v is a plan view, ``Partly broken.

that their direction of rotation will be reversed upon a reversal of the direction of travel of the vehicle. 1

Referring to the above drawings, a designates a vehicle body, the top of which is provided with a radiator b vvertically mounted at the rear. This radiator may be formed with a plurality of sections, in the present instance two being shown, and each section i.

in accordance with the direction of travel of i the vehicle and Figure If 'illustrates, diagrammatically, a suitable connection for the motors. Control switch f, which controlsthe movement of lthe vehicle, is rovided with field contacts f' for'reversin t e fields of the motors upon movement o the switch in either direction. Batter g is connected to the movable contacts f2 o the switch and also to the armaturesh ofb the fan motors. The

motor fields k' are connected to the contacts and the circuit through the armatures and attery is completed through contacts fs. lt will be seen that movement of the switch f into either direction will cause the fans to be rotated in a correspondingdirection inl accordance with the movement' of the vehicle.

Tt'will be seen that the available space for mounting radiators is practically Unlimited and adequate cooling may be provided by a suitable design of cooling unit. While the,

invention has been described in connection tid eof i with the accompanying drawings, it is not comprising a radiator, means for mounting i the radiator upon the roof of the vehicle, a

hood associated with the radiator, means within the hood for creating a flow of Cooling air therethrough, and means to reverse the direction of the flow creating means when the direction of movement of the vehicle is changed. i 2. A Cooling system for a vehicle having a control for reversing the inovement thereof, Comprising a radiator, means for mounting the radiator upon the roof of the vehicle at the rear thereof, a hood associated with the radiator, a door at the end of the hood to restriCt the flow of air therethrough, means within the hood for creating a flow of Cooling air therethrough, and means to reverse the direction of, the flow Creating means When the directionof movement ofthe Vehicle is Changed.

3. A Cooling system for a vehicle having a Control for reversing the moyement thereof, Colnprising a radiatorwmeans for mounting the radiator upon the roof of the Vehicle at the rear thereof, a hood associated with, the radiator, a door at the end of the hood to restriCt the flow of air`therethrough, a fan within the hood for Creating a flow of Cooling air therethrough, and means to reverse rthe direction of rotation of the fan When the direction of Inovement of the vehicle is Changed.
