JOHN WILKINSON, 0F SYRACUSE, NEW YORK, ASSIGNOR TO H. FRANKLIN MANU- FACTURING COMPANY, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.

AIR-COOLING SYSTEM FOR INTERNAL-COMBUSTION ENGINES.

Application filed November 16, 1911.

To all whom it may concern:

Be it known that I, JOHN WILKINSON, of Syracuse, in the county ofOnondaga and State of New York, have invented a new and useful Air-Cooling System for Internal- Combustion Engines, of which the following is a specification.

This-invention has for its object the production of a particularly simple and" efiicient air cooling system for the internal combustion engines of motor vehicles; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure l is a transverse sectional view of a portion of a vehicle embodying my inven tion, parts of the engine being omitted. Fig. 2 is a transverse sectional view of the casing for the engine, contiguous parts of the frame of the vehicle being also shown. Fig. 3 is an inverted plan of the hood. Fi 4 is a detail view. of the arch around t e upper portion of the fan. Fig. 5 is a fragmentary view of the hood, looking forwardly, illustrating one of the depending flanges carried by the hood.

1 are the sills; 2 designates the dash board, and 3 the engine of a motor vehicle, the engine comprising a plurality of cylinders 4 arranged one behind the other or tandem, and having lengthwise flanges 5.

6 is the crank shaft of the engine.

This air cooling system for internal combustion engines comprises, generally, a casing inclosing the engine, such casing including a removable hood and means dividing the casing into upper and lower compartments, and means as a fan for circulating the air through the casing.

7 is the removable hood which normally rests at the lower edges of its side walls on the sills 1, and which is pivoted at 8 near its front end to the sills land is movable.

ends thereof, and being secured at their spaces betweenthe side edges of the wall 11 and the side walls of the hood are closed by flanges or wings 12 carried by the hood and extending downwardly from the frontedges of the wings or partition sections. The partition section 10 is formed with passages through which the. cylinders 4 project, and preferably these passages are confined by cylindrical shells 13 supported in openings in the partition 10 and surrounding the flanged portions of the cylinders.

.14 is a boot, or pan, constituting the bottom and portions of the side walls of the casing. The boot, or pan, is closedat its front end by the upright wall 11 which is provided with an axialbpening 16 through which extends a bearing 17 for the crank shaft 6. The boot or pan 14 is suitably supported by thesills 1 and is here shown assecured thereto in any suitable manner as by bolts 18 engaging with the horizontal flanges of angle irons 19 secured to the inner faces of the sills 1.

The hood is usually provided with a screened air inlet opening 20 at its front end and also'such front end overhangs the front wall 11, and is open at 21 for permitting the inlet of air, and a deflector 22 is located below the opening 21 for directing the air upwardly through such opening 21. Additional side deflectors, as the deflector 23, are also provided between the sills and in front, of the deflector 22. v

The means for circulating the air through the casing is here shown as a peripherally discharging suction fan 24 mounted-on the rear end of the crank shaft 6, the upper portion of such fan running close to an arch 25carried by the dash board 2 of the vehicle, and the lower portion of the fan running within an extension 26 of the boot or pan 14. Said arch 25 is provided with flanges 27- at its ends, which depend between the sills 1 and meet the upper ends of a semi-annular flange 28 within the rear end of the boot or. pan 14. The parts 25 and 28 form an outlet opening for the casing through which the air-is drawn by the fan 24 located in the rear of said opening.

The fan 2% is here shown as'containing a suitable disk clutch 29 and a universal joint. 3Ov through which power is transmitted to the driving wheels of the vehicle.

In operation the air is drawn through the openings 20 and 21 to the portion of the hood above the partition sections-9 and 10 and is drawn downwardly through the passages 13 into the boot or. pan 14k and isdischarged through the rear end pf the pan 14 The air is prevented from entering below the partition sections 9 and 10 by the front wall lland the Wings 12.

This air cooling system is particularly advantageous in that upon the removal of the hood, portions of the casingare removed therewith so that parts andappurtenances of the engine within the boot or pan or below the partitions 9 and 10, are easily accessible.
