A. P. CLARK ENGINE COOLER Filed Sept. 26. 1923 AU. (747v? ARCHIE I. CLARK, or oxanaean CENTER, BRITISH COLUMBIA, CANADA.

ENGINE COOLER.

Application filed September 26, 1923. Serial No. 664,878.

To all whom it may concern Be it known that I, ARCHIE P. CLARK, citizen of the United States, residing at Okanagan Center, in the Province of British Columbia and Dominionv of Canada, have invented certain new and useful Improvements in Engine Coolers, of which the following is a specification.

This invention relates to certain new and useful improvements in cooling devices for multiple cylinder internal combustion engines and has particular reference to air cooling devices for engines of this kind.

The primary object of the invention is to provide an air cooling device for the cylinders of multiple cylinder internal combustion engines, by means of which said cylinders may be efficiently cooled, and which embodies the desired qualities of simplicity and durability of construction, so that the device may meet with the requirement for a successful commercial use.

4 Another object of the invention is to provide a construction which represents a slight modification of the commonly employed water cooled internal combustion engine and by means of which the cooling system is materially simplified.

Other objcet-s will appear as the nature of the invention is better understood and the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed:

The view is a side elevational view of a multiple cylinder internal combustion engine equipped with an air cooling device constructed in accordance with the present invention.

Referring more in detail to the drawings, 5 indicates an ordinary multiple cylinder internal combustion engine employed as the diaphragm of a motor vehicle and in ordinary practice, these engines are provided with double walled cylinders so that a jacket is provided about each cylinder with the several jackets in communication with an outlet 6.

In accordance with the present invention, the several jackets of the engine cylinder are usually supplied with air through a manifold 7, communicating with the tops of the jackets of the cylinders as shown clearly in the drawings, the lower ends of said jackets being each in communication with. the outlet 6, and said outlet being in the form of a manifold which extends rear- .wardly and is open at its rear end as at 8.

A suitable fan blower 9 is substituted for the cooling fan at the forward end of the engine, the same being suitably mounted upon the bracket 10 and the impeller of this blower is driven by the usual belt 11 passing around a pulley fixed upon the shaft of the impeller of the blower 9 and around the pulley 12 on the forwardly projecting ends of the shaft 13 of the motor. The side outlet of the blower 9 is connected to the manifold 7, and this blower is provided with a front intake as at 14.

In order to more efliciently cool the cylinders of the engine, a branch pipe 15 has its forward end in communication with the forward portion of the manifold 7 and extends rearwardly above and in close proximity to the top of the engine, suitable perforations being provided as at 16 in the branch outlet 15 above each cylinder so as to permit a blast of air to be directed onto the latter.

In operation, the impeller of the blower 9 is rotated as soon as the engine is started for throwing a continuous supply of air into the intake 14, and this air is forced by the blower through the manifold 7 into the jacket of each of the cylinders. When this air has served its cooling function and passes out of the jacket into the manifold 6 where it is exhausted at the rear of the engine at the open end 8. A portion of the air supplied to the manifold 6 Will pass through the branch outlet pipe 15 and be sprayed onto the'top of the engine through the opening 16 for additional, cooling purposes.

' A cooling device constructed in accordance with the above will be found extremely eflioient, will render the use of a water radiator unnecessary, and will not interfere with ready access to the engine for repair.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is: v

The combination with a multiple cylinder internal combustion engine of a motor vehicle, having the cylinders of the engine provided with jackets through which a cooling fluid may circulate, a manifold communicating with the tops of the jackets of all of said cylinders, a fan blower rigidly supported at the front end-of the engine end hevin an outlet communicating with 'eeid fen blower being proeeid mani old vided with n front intake, means for teciliteting operation of the blower h the 6 gine an outlet. manifold exten i Werdly of the engine and commnmceting -with the bottoms of eeid jackets, end e .hrench outlet pipe being formed on the first Q mentioned menifold and q extending reorwardly end longitudinelly of end eloove the the upper portions of the cylinders wnere excesewe tent s genereted.
