WATER COOLER.

Specification of Letters Patent.

Patented Jan. 17, 1922.

Application filed January 12, 1921. Serial No. 436,641.

To all whom it may "concern Be it known that I, Evnnnrr B. CUsHMAN, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Water Coolers, of which the following is a specification.

My invention relates to the class of water coolers, and particularly to that type in which a radiator is associated with a flywheel and is exposed to a current" of air induced by the: rotation of said wheel. ater coolers of this type are especially adapted for the cooling systems of internal combustion engines, and in this connection I shall herein illustrate and describe my invention though it will be understood that it is not necessarily confined to this use.

Th'e'obj'ect of my invention is to provide a simple and eflicient water cooler of this type; and to this end, my invention consists in the novel water cooler which I shall now fully describe by reference to the a'ccompairving drawings, in which-- Fig. 1 is a part sectional side elevation of my engine, showing the position of the radiator and the arrangement of the cooling system.

Fig. 2 is a part sectional rear elevation of the radiator and fiy-wh'eel, taken in the direction of the arrows on the line 2-2 of F ig. 1.

Fig. 3 is a vertical section, enlarged, of a portion of the radiator.

In the drawings and referring particularly to Fig. 1 thereof, the reference numeral 1 designates the base or crank-case of an engine, from which projects a crankshaft 2 carrying a fly-wheel 3. l designates the engine cylinder, and 5 the head thereof. It is to be understood that said crank-case, shaft, and cylinder may be formed in any well-known manner, and further that the other usual parts, viz. piston, connecting rod, valve gear, etc., not shown in the drawings, may be mounted and constructed in any manner consistent with customary practise.

The cylinder 4 is surrounded, wholly or in part, by a jacket 6, for water or other cooling fluid, which communicates by a series of openings, one of which is shown at 7, with a water chamber 8 formed in the cylinder-head 5. Said chamber 8 is relatively large, as shown, and forms a convenient reservoir for containing a supply of the coohng fluid, in addition to providing a cooling jacket for the head 5. A removable cover plate 9 provides access to said reservoir for cleaning. A water pump 10 is suitably mounted on the engine base 1, and has its intake connected with the reservoir 8 by a conduit 11.

The fly-wheel 3 has an apertured web 12, as shown in Figs. 1 and 2, and an ofi-set rim 13, in which is formed a series of fan blades 1&. A stationary radiator 15 is mounted within the off-set rim of said flywheel, and is provided with water inlet and outlet connections 16 and 17 respectively. Said radiator is supported by said connections, which have studs 18 secured to upper and lower arms of a fixed bracket 19. Fig. 1, secured to and projecting laterally from the engine base 1. A drain aperture 20 is formed in the inlet connection 16, which may be closed by any convenient means, not shown. and which, being at the lowest point in the water circulating system, provides means for draining the water therefrom. The radiator inlet connection 16 is connected by a conduit 21 with the discharge connection of the pump 10, and the radiator outlet connection 17 is connected by a conduit 22 with the lower portion of the cylinder jacket 6.

The radiator 15 comprises a series of laterally spaced annular chambers 23, Figs. 1 and 3, each of which is formed by joining together two similar but oppositely positioned annular plates 24, Fig. 3, whose peripheral edges are upset and flanged, as shown at 25, and joined together, preferably by soldering, as at 26. The annular plates 2 1 are formed with diametrically opposite flanged apertures 27 and 28, the interior diameter of the apertures 27 being the same as the exterior diameter of the apertures 28, so that the flanges of the apertures of adjacent plates telescope and may be joined together, preferably by soldering, as shown at 29.

By this construction I am enabled to form the entire radiator of a series of identical members, viz. the plates 24, one of the two plates forming each chamber being reversed and rotated 180 degrees with respect to the other, so that the larger'aperture 27 of one plate is aligned with the smaller aperture 28 of the other. These plates can be easily and cheaply formed, by stamping, from rela- Cit tively thin sheet metal, so that the entire radiator structure is both light and inexpensive. The plate forming the back ofthe radiator is blank, without apertures, and the front plate has the supporting inlet and outlet connections 16 and 17 secured to it in any convenient manner, as by soldering and riveting.

The blades 14: in the rim of the fly-wheel cause a current of air to be drawn in axially to the center of the radiator, and then radially outwardly between the spaced chambers 23, while the water, entering through the bottom connection 16, flows upwardly through said chambers and out by the upper connection 17, giving up its heat to the walls of said chambers in passing therethrough. The fly-wheel thus acts as a fan to set up a current of air over the radiating surfaces, and at the same time as a protectlon to prevent injury to the radiator.

' My invention has been herein described and is herewith illustrated in its preferred form, but it is to be understood that changes may be made in its form and construction,

within the scope of the claims hereto ap-c pended, without affecting the essentials of the invention or departing in any degree from the spirit thereof.

I claim 1. A water-cooling means comprising a -fly wheel having an apertured web and an offset apertured rim with a series of spaced fan-blades; and a stationary radiator lying -within the space circumscribed by the offset rim of the fly-wheeland exposed to a current of air drawn in centrally of the radiator and exhausted through the 'apertured rim of said fly-wheel.

2. A water-cooling means comprising a fly-wheel having an offset apertured rim with a series of spaced fan-blades; and a stationary radiator lying within the space c'ircumscribed by the offset rim of the fly wheel and exposed to a current of air drawn in centrally of the radiator and exhausted through the apertured rim of the fly-wheel. 3; water-cooling means comprising a fly wheel having an offset apertured rim bers, said plates lying within the space circumscribed by the offset rim of the flywheel, and exposed to a current of air drawn in centrally of the radiator and exhausted throu 'h the apertured rim of said fly-wheel.

4. K water-cooling means comprising a fly-wheel having an ofiiset apertured I and fan-bladed rim; and a stationary radiator lying within the space circumscribed by the offset rim of said fly-wheel and composed of a series of similar circular plates, each plate having peripheral flanges on one face and a pair of diametrically opposite flanged apertures in the other face, the interior diameter of the flange of one aperture being equal to the exterior diameter of the flan e of'the other aperture, and said plates ein arranged in pairs, one plate of each pair eing reversed and rotated 180 degrees with respect to the other, the adjacent peripheral flanges of said plates being joinedto form a water-tight chambertherebetween and the aperture flanges of each pair of plates being telescoped into and joined with those of the adjacent pair to form water connections between said chambers.

In testimony whereof I have signed my name to this specification.

EVERETT B. CUSHMAN.
