Application filed June16, 1917. Serial No. 175,132.

To all whom it may concern:

Be it known that I, JOHN A. KERNPHAN, a subject of the British Empire, residlng at Saranac Lake, in the county of Franklin and' State of New York, have invented certain to a combined cooling and car heating system. One object of the present inventlon resides in certain im 'rovements in the manner of directing and rawing a current of air past the engine cylinders. Otherobjects reside in the provision of means for heating the carby means of the air which has been warmed in passing the engine cylinders.

In the drawings- Figure 1 shows in elevation an automobile in which my improvements are incorporated.

'Fig. 2 shows a detail cross. sectional view of the motor and shows the paths of the air cooling currents. s

In more detail in the drawings-- a M is a motor'having cylinders 10, 11, 12 and 13. These cylinders may be provided withcooling fans, if desired. B is the body of the car having a drivers compartment D and a tonneau T. H is a hood and R is a gratin at the front of the hood which is shaped in semblance of the usual water radiator. Carried by the base of the motor and projecting upwardly therefrom are two sheet metal plates 15, 16, having a sinuous contour, as learly shown in Fig. 2. A top plate 17 is secured to and bridges the side plates and is also secured to the cylinders 10, 11, '12 and 13. Plates 15, 16 and 17 form a chamber about the engine cylinders. The

front of this chamber carries two concentric funnels18- and 19,,the imi r funnel having a tube extending rearward y and upwardly, as shown at 20. Within the forward end of funnel 18 is a fan 21 which is revolubly supported upon a bracket carried b the screen structure. The fan is suitably. riven by a belt which is rotated by the engine crankshaft. At the front of the first cylinder 10 is a baflle 22 which prevents the air: currents from impinging directly upon the; forward portion of the. first cylinder. I alsoprovide a curved bailie late 23 which extends from the side of cyhnder 10, to the side of cylinder 12. This bafile serves to direct a portion of the cool air current directl from the front of the casing to the rear cy ders 12 and 14. I have found that the concentric funnels introduce decided advantages in the proper cooling of the cylinders as they make the air currents set up by the fan more uniform in the intensity of flow at difierent places. The bafiles 22 and 23 also cooperate to uniformly cool the various cylinders instead of cooling the forward cylinder more than the rear cylinder as has been the case by means of the ejector exert a considerable suction uponthe cooling air'and thereby aid the fan in cooling the engine.

(Jar heating devices.

Connected with duct 24 are branch ducts 27 and 28 which extend to the tonneau T and the drivers compartment D, respectively. These ducts terminate at suitable -registers 30 which may be opened or closed at will to control the entrance of heated air to the driving compartment or tonneau.

For convenience in illustration I have shown duct 24 as being restricted in area. It will be understood that this duct will be of suitable size to conduct. the cooling air out'of the chamber without back pressure. The duct may also pass directly through the dash to the tonneau with a depending branch leading to the ejector.

The mufller pipe 26 is provided'with a Inuffler 31 and leads to a'manifold 32 which it will be noted is above plate 17. Parts 32 arethe cylinder heads making them readily removable without removing the plate 17. As shown in Fig. 2,,the valve push rods '33 are without the air casing. The feature of having these parts without the air cooling casing I' consider desirable since it elimi-' hates the possibility of oil or exhaust fumes commingllng withthe cooling air. Such a mixture of noxious fumes and air is undesirable when the air is to be used for heating purposes. V

It will be understood that. my invention may be modified in various ways as will occur to those skilled in the art.

gitudinally disposed cylinders within the hood. a casing surrounding the same, having an air inlet opening in front for cooling air and an outlet in the rear for the egress of air, and battle plates within the casing forming passages for the air, one of said passagesincluding all the cylinders, and the other being adapted to divert a portion of the re ceived air from the front cylinders and directly upon those in the rear.

3. In a device of the class described, in combination, a plurality of longitudinally disposed cylinders, a longitudinally disposed sinuous casing inclosing the same, a curved battle in said casing adapted to'direct cooling air to the rear cylinders without permitting the air to contact with the intervening cyl inders, the aforesaid sinuous curvature of the casing being also adapted to cooperate to direct the passage of air through the chamber and about the cylinders.

4. In a device of the class described, in combination, a plurality of longitudinally disposed cylinders, a longitudinally disposedsinuouswcasing inclosing the same, a curved battle in said casing adapted to direct cooling air to the rear cylinders without permitting the air to contact with the intervening cylraoaooo inders, the aforesaid sinuous curvature of the casing being also adapted to cooperate to direct the passage of air through thechamber and about the cylinders, and apair of concentrically disposed cone-shaped members associated with the front of the casing and being adapted to direct the air into the same.

-5. In a device of the class described, in combination, a plurality of longitudinally disposed cylinders, a longitudinally disposed sinuous casing inclosing the same, a curved balile in said casing adapted to direct cooling air to the rear cylinders without permitting the air to contact with the intervening cylinders, the aforesaid sinuous curvature of the casing being also adapted to cooperate todirect the passage of air through the chamber and about the cylinders, and a pair of concentrically disposed cone-shaped members associated with the front of the casing and being adapted .to direct the air into the same, the inner of said cones having an upwardly directed outlet opening to direct a portion of the air upwardly.

6. In an air cooling system for automobile engincs, the combination with a plurality of cylinders within the-hood, casing surrounding the same, a pair of concentric cones for directing received air through the casing, a rotary fan for delivering an air blast into the cones, a duct leading from the rear of the casing for carrying off the warmed. air, anin' ector-Iocated in the rear part of said duct. and a mufller pipe associated with the ejector and leading the exhaust gases from the engine thereto for set-' ting up a suctiomto assist inwithdrawing the warmed air from the system. I

In testimony whereof I affix my signature.
