Vhen a sell-propelled vehicle is driven up hill a great deal et heat is generatedkin the operationr ot the prime mover, which, in
respect ot a water cooled linternal. combus tion engine kas the'prime mover is dissipated by the radiator. does practically no work, little heat is genkrerated, and the ten'iperature of the Water f inthe radiator is greatly reduced.' rlliis lrluctuation inthe temperature ofthe Water in the engine cooling system Lvaries proportionately the temperature ot the Walls of the yengine cylinders with the consequent dis` advantages `in, operation inherent therein. The object ot'the present invention is the [maintaining of the iuid in the cooling system and hence the walls oli the engine'cylinfluid, water, oil or the like, circulates' through a radiator and engine acket under the intiuence of the usualpump and the cooling `fluid also circulates through the radiator and a jacket or jacketssurrounding 3,5 braking devices under the Vinluence of another pump. g f
Another object of the invention yresides in 'the method by ,whichk the foregoing yresults are attained( In its broadest aspects the 40 method is one of governing temperature conditions in a plurality of units the ymajor portionsy of Whose Work is not performed simultaneously and consists in circulating a cooling niedium'betvveenv such units and y a heat interchanging device. In they specific embodiment illustrated herein they method y is one of governing thek operating temperaf tures of the engine and a brake or brakes by circulating a liquid between a radiator and the engine and brake means.
In orderthat the invention may be clearlyL understood and readily carried into effectr the same will noW be described with greater l particularity in connection with the ac- Going down hill the enginev degree to maintain the walls oli Apgiiieaeon ined January 19,1926. serial No. 82,229;
conipanying iilrawing illustrating somewhat diagrainmatically one embodiment thereof wherein a water cooled brake on the propellershalft is in circuit with the radiator Acooling an internal combustion engine on a selipropelled vehicle.
A cooling fluid such as water, oil or the like 'is drawn by the usual pump L from a radiator I) carried on the frame m of a. self-propelled; vehicle to the water jacket c ot an internal combustion engine from whence it is returned to the radiator through a pipe t kin the customary manner. llfater from the radiator is also conducted by a pipe Z to the water jacket e of braking devices.r In the illustrated embodiment the braking devices comprise a brake f on the propeller shaft g.y From the Water jacket ot the brake the kcooling medium is drawn or propelled, as by a pump i, in this instance actuated troni the change speedinechanism y', through pipe k back to the radiator.
f Thus when the vehicle is being driven up a hill theoperation of the engine Will tendto raise the rtemperature of the Water in the circulatory system whereof. the radiator kis designed `to dissipate heat to a certain the engine ycylinders at that temperature most conducf tive to ellicient operation. W'hen the vehicle is subsequently descending and the engine doing little work, the Water inthe circulatoryy system which ivouldhave a tendency ordinarily, to cool, is maintainedat substane tially the same vdesirable temperature by a heat interchange with the braking devices which aie broi'ight into action iii the descent. The invention is not to be deemed limited to the precise disposition o'l'parts illustrated in the drawing nor to the manner of eifecting the circulation ofthe cooling medium, but various modifications of the system as aWhole or its application and the fluid therein will occur and are to be deemed Within the scope of the invention so long as they maintain the eHective operating temperature of the Working units Within effective yranges.
