nxrnosron ENGINE.
Application filed September 24, 1919. Serial No. 326,191.
T 0 all whom it may concern Be it known that I, JosnPH L. CATO, a citizen of the United States, residin Elmhurst, in the county of Queens and tate of New York, have'invented a certain new anduseful Improvement in Explosion Engines, of which the .i'ollowing is a specification. j p i My invention is applicable to internal combustion engines of many different kinds,
but is especially applicable to such engines used for driving automobiles or aeroplanes. .The ob ect of my invention is to provide an internal combustion engine having an effective coolingmeans, which is of such character that an engineprovided with said cooling means will have less weight than the engines using previouslyknown cooling 7 of the engine. t
Further objects of my invention will appearfrom the detaileddescription thereof contained hereinafter."
.While my invention is capable of embojdiment in many diflerent forms, for the purpose of illustration I have shown only one form of the same in the accompanying drawings, in which:
Figural is a cross-section of a portion of an engine cylinder and piston made in accordance with my invention,
Figure 2 is a bottom View of said piston;
Figure 3 is a transverse section of said piston; and
Figure 4 is another transverse section of the same taken on line M of Figure 3.
In the drawings, I have shown a cylinder 1 of an aeroplane engine of internal combustion type, having at the top thereof a closure 2, provided with a spark plug 3 at one side thereof, an inlet port 4; for a fuel mixture, controlled by a valve 5, and an outlet port 6 for the products of combustion, controlled by a valve 7 In the cylinder 1, there is provided a port 8 for the passage of air, which at all times communicates with a longitudinal passagetransverse strengthening partition 13. the passageways 12 there are a plurality of transverse fins 1 1, to increase the cooling eliect of the air. piston 10 opposite to the location of the way 9 on one side of a piston 10, the lower endof which passageway 9 isclosed by'a flange 11, but the upper end of which is vopen to communicate with a plurality of transverse passageways 12,"formed by Ia n ()n the side of the passageway 9, there is a further passageway 15, which is open at the top, but the lower end of which is closed by a stationary piston 16, carried by the lower end of thecylins der 1, and held in place by a plurality of screws 17, passing from the cylinder 1 into a crank casing 18. It will also be noted that the passageways 9 and 15 are connected by a hollow crank pin 19, held in place in the piston 10 by a screw 20, and which supports a connecting rod 21. cooling is secured in this way. If desired, a still greater cooling eiiect may be obtained by providing fins 22 on the outside of the cylinder 1.
In the operation of my invention, as the piston 10 reciprocates, currents of air are first drawn in through the port 8 upon the upward stroke of said piston, and are forced out through the port 8 upon the downward stroke of said piston, owing to the pres.
ence of the stationary piston 16. These currents of air pass not only over much of the interior of the piston 10, but come into contact with the cooling fins 14, aswell as the interior of the crank pin 19, so that the cylinder 1 is effectively cooled from the inside by these currents of (t11. 'A further cooling effect is secured by the presence of the fins 22 on the outside of the cylinder 1.
While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit of the same.
I claim:
1. An internal combustion engine having in a cylinder means for providing therein a current of air, comprising a stationary partition cooperating with an engine piston and fitting in a passageway located at one side of the piston.
2. An internal combustion engine having in a cylinder means for providing therein a current ofair, comprising a stationary par- Additional tition cooperating with an engine piston and fitting in a passageway located atone side the piston in contact with said current of air.
5. .An internal combustion engine having in a cylinder means for provldingthereln a current of air, comprising astationaryrpar- ;tit-ion cooperating with an engine piston and fitting in a passageway located atone side of the piston and a fin extending transversely through the piston in contact with said current of air.
6. An internal combustion engine having in a cylinder means for providing therein a current-of air, comprising a stationary partition cooperating with an engine piston, a continuously openport in the cylinder, and
