July 28, 1931. .1. B. STRAUSS' INTERNAL COMBUSTION ENGINE Filed July 20, 1927 Patented July 28, 1931 UNITED STATES JOSEPH B. STRAUSS, @F CHICAGO, ILLINOIS INTERNAL COMBUSTION ENGINE 7 Application filed July 20,

This invention relates to improvements in internal combustion engines and has for its object to provide a new and improved engine of this description.

The invention has as a further object to provide an air cooled internal combustion engine.

The invention has as a further object to provide an air cooled internal combustion engine for use on flying machines, automobiles or other moving bodies;

The invention has other objects which are more particularly pointed out in the accompanying description.

Referring now to the drawings, Fig. 1 is a view showing one form of the device embodying the invention.

Fig. 2'is a sectional view through the tube showing the engine in position.

Like numerals refer to like parts throughout the several figures.

I have shown in the drawings, an internal combustion engine arranged in a tube and adapted to be mounted upon a moving device which is driven forward. by the engine 'so that as the-device moves forward, air Wlll.

pass through the tube and around the engine so as to cool the engine.

In the construction shown, the engine 1 is encased in a tube 2 open at the front and rear ends. The cylinders 3 of the engine are to provide an oil radiator.

preferably provided with cooling fins 4 so as to assist in the proper cooling of cylinders. This tube preferably extends beyond the engine and may be used as a part of the frame of the structure which the engine'is used to drive.

prefer to arrange this tube with enlarged front and rear ends, the tube being contracted between its ends as at the point 5 so as to form a Venturi tube. I also prefer 6 located in the path of the air current and through which the lubricating oil is pumped so as to be cooled by the current of air passing through the tube. When the device. driven by the enginemoves forward, air entering the front end 7 of the tube passes around the engine and passes out through the discharge end 8 of the tube carrying theheat with it and dis tive that the lubricating oil the 1927.

charging said heat at a point where it cannot affect the engine. The exhaust of the engine may pass into the tube 2 so as to act to increase the velocity of the air passing therethrough, this discharge producing an e ejector action. It will be seen that by means of the venturi and this exhaust, the cooling air will pass through the tube and around the engine at a high velocity as the engine is moving forward'and that the cylinders of co the engine may thus be effectively and efficiently cooled without the use of a water cooling system.

In the construction shown in Fig. 2,the exhaust pipe 9 of the engine is shown as exhausting at a point beyond the contracted portion of the tube. The tube 2 is also provided with suitable doors 10 by means of which access to the engine is secured. By means of this device I secure a much lighter weight for any given engine. The cooling is also greatly simplified and made so effecdoes not become burned and can be used for a much longer period. When the engine is used on an automobile, for example, such automobile will be of lighter weight. In such use, the tube 5 may extend through the central portion of the machine and may form, as it were, a back bone to the entire structure. This '80 eliminatesthe squeaks from the engine.

By means of this construction, the elaborate, heavy chassis bracing may be eliminated. When used in an automobile the tube forms a compartment around the engine which permits leg room'to be extended around the engine on each side thereof. This permits the shortening of the body and the Wheel base. Since the engine is encased in the tube, the noise is reduced. By means of this tube, the heat from the engine may be discharged at the rear of the device so as not to affect the occupants.

In the construction shown the-seats 11 are arranged at opposite sides of the tube 5 2, lubricating oil is moved through the cooling, radiator 6 by means of a pump. 12 and the pipe 13. The tube 2 is provided with cross supporting members 1 15, and 16.

The engine is used to drive the device with 1 2 retailer which it is associated and when it is a moving device, to drive it forward.

In the construction shown, the engine is illustrated as being connected by the drive shafts 17 with the rear axle 18 of the automobile.

ll claim:

1. An internal combustion engine, comprising a plurality of cylinders, a tube ha ing a central contracted portion and enlarged front and rear ends, said enlarged ends being enlarged both vertically and horizontally, said cylinders being located in the enlarged front end of said tube, and means for moving air through said tube past said cylinders so as to cool the same.

2. An internal combustion engine comprising a plurality of cylinders, a tube having a central contracted portion and enlarged front and rear ends, the enlarged front and rear ends being substantially the same size, said cylinders being located in the enlarged front end of said tube, and means for discharging the exhaust from said engine into the enlarged rear end of said tube to cause air to move therethrough.

3. A device of the kind described comprising a frame having a hollow, strengthening member enlarged at the front, and rear ends and contracted near the middle, both ends being open, an engine located in the front end of said hollow, strengthening member at a point back of the opening therein, the cross sectional area of the hollow, strengthening member at the point where the engine is located being smaller than the cross sectional area of the open end of said member.

Signed at Chicago, county of Cook and State of Illinois, this seventh day of July,

JOSEPH B. STRAUSS.
