Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed December 2851906. Serial No. 349.824.

- more particularly to means whereby the enexplosive 'gine cylinder may be cooled by air delivered to the carburetor and also by means of the mixture delivered to the inlet valve. j

The object of the invention is to provide an improved construction wherein the air delivered to the carburetor is heated by radiation and a richer'mixture thus produced in the carburetor, and this richer mixture is also heated by radiation from the engine" cylinder before being ignited within said cylinder.

The invention consists in certain features of construction and combination of parts, all of which will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is to be h'ad'to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, in which 7 Figure 1 is a side elevation of the engine cylinder, the outer jacket being shown in section; Fig. 2 is a longitudinal section through the engine cylinder and jacket; Fig. 3 is a transverse section on the line 33 of Fig. 1; Fig. 4 is a transverse section on the line 4= 4 of Fig. 2; and Fig. 5 is a development of the'outer surface of the cylinder.

In my im roved construction I employ a cylinder 10 aving a cylinder head 11 either rigidly secured thereto or integral therewith,

and within the head is located the inlet valve 12 and the exhaust valve 13. [These valves are supported by

valve stems

14 and 15, and may be operated by means of'cams or in any other suitable manner well known in the art. Adjacent the inlet valve is located the spark plug 16 for igniting the explosive mixture, and within the cylinder operates any suitable form of piston 17 and piston rod 18. As these arts do not constitute an essential portion 0 my invention, and as any suitable construction may be emloyed, further description of the specific etails illustrated is not thought to be necessary.

The outer surface of the cylinder is prov vided with a plurality of flanges so arranged mares.

as to form a plurality of passages intermediate the cylinder and the jacket 19, which latter is provided .with a plurality of flanges or other heat-diffusing elements 20 of any suitable character for radiating the heat, and

thus maintaining the cylinder at the desired temperature. surface of the cylinderll], not only serve to form the passages above referred to, but also serve to support and hold in place the jacket 19. lgigidly secured to the jacket, adjacent the end of the cylinder farthest from the inlet and exhaust valves, is secured The flanges upon the outer a conduit 21 communicating with the space between the cylinder 10 and the jacket 19 and having its outer surface provided with The conduit is sub-divided ya partition 23 to form two separate passages, and its .outer end is provided with a flange 24 whereby the end of the conduit may be connected directly returned from said carbureterthrough the other passage.

The arrangement of flanges upon the outer surface of the cylinder 10 is clearly illustrated in the development of the outer surface of said cylinder shown in Fig. 5. The opposite ends of the.cylinder are provided with flanges 26 of greater thickness and strength than the remaining flanges, and these serve for engagement with the jacket at the ends of the latter to support said jacket and hold it in the desired position. One of the flanges 26, namely, the one far-- thest from the inlet and exhaust valves of the engine, is imperforate While the other flange 26 is provided with an opening 27 communicating directly with the atmosphere and serving as an inlet for the air which is to be second flange 29 lying substantially parallel thereto throughout the greater portion of its rality of circumferential flanges-31 31 31 flanges 32" and 32 lying and 3.1, each of which is connected to the longitudinal flange 29 and all of which exceptthe flange 31 terminate a short distance from the' longitudinal flange 28. Intermediate the

flanges

31 and 31 and intermediate the

flanges

31 and 31, are two ar allel thereto and connected to thelofi g'ftn inal flange 28 and spaced a short distance from the longitudinal flange 29. The flange 29 terminates at the flange'31 which lies farthest from the inlet and exhaust valves of the engine, and the passage 30 between the

flanges

28 and 29 thus communicates with a passage 83 lying between the end flange 26 and the adjacent flange 31 WVithin the passage 33 is a short longitudinal flange 34 extending from across said passage and adapted to engage with the inner end of the partition 23 of the conduit 21, whereby the two passages of said conduit communicate with the passage 83 upon different sides of said flange or partition 34:. As the flange 31 terminates a short dlstance from the flange 28, a passage {is formed, whereby-communiontion is established between the space below the flange 31" and the passage 33 lying between the flange 31 and the flange 32 The passage 33 extends from the partition or flange 28 around the cylinder to the partition or flange 29 and communicates with the passage lying between the

flanges

32 and 31 which in turn communicates with the passages lying above each of the next successive pairs of ad acent flanges above referred to; A1133.- cent the flange 31" 1s a flange 32 which ter-' -min ates a short distance from the flange 28,

but also terminates a short distance from the flange 29; this construction being necessary to permit the passage of the gas around the bushing 35 through. which is inserted the spark plug" 16. I

Above the flange 32" is a flange 31 in engagement with both of the

flanges

28 and 29, and having an opening leading from the passage between. theiflanges 32 and 31 to the chamber 36 at the end of the cylinder and adjacent the inlet and outlet valve casings. This chamber sub-divided by a circumferential partition 32 lying intermediate the partition 31 and the terminal flange 26, and having a plurality of passages therethrough. The space intermediate the partition 32 and the terminal flange 26 is sub-divided by a longitudinal" partition 37 and again by the bushing 38 surrounding the exhaust ort 39.

The casing of the inlet valve is'provi ed with an inlet port 40 leading from the valve cham her to the passage intermediate the part1-

tions

31 and 32 and this last 'mentioned passage communicates with the assage in- ,termediate the partition 32 and t e terminal flange 26. I

By means of the artitions, passages and ports above referrer? to, the air may freely of the passages in the conduit 21, as indicated by the arrows on Fig. 5., The air becomes charged withthe fuel at the carhu} reter and flows back to the engine through the remaining passage of the conduit 21 and is delivered into the passage 33 upon the o' .air. The fluid mixture flows a most entirely around the cylinder after flowing into the passage 33 and travels almost entirely around the cylinder at second time. It then 32* and 31 and so on back and forth around the cylinder until it reaches the inlet valve 40 and. is admitted to the cylinder through the inlet valve 12, followingthe path also indicated on Fig. 5 by means of the arrows. It will thus be noted that the atmospheric air around the same before being delivered to the carbureter. tain heat fronrthe cylinderwall, and this heat is in turn partially radiated to the outside atmosphere .by means of the flanges 20. More of the heat within this air is radiated While said air is flowing through the conduit 21, but when the air arrives at the carburetor it is still in. a somewhat heated condition. By delivering the air to the carbureter in a somewhat heated condition, the gasolene or other fuel is much more readily eva orated and afar richer mixture is obtaine The vaporizing of the fuel serves to further reduce the temperature of the air, and the air thus cooled by radiation and vaporization is then circulated back and forth around the latter and to heat the fuel to such a temperature that the most advantageous results may be secured. explosive mixture is circulated not 'only around the outer surface of the cylinder, but also in contact with the ends thereof, and the proper working condition.

It is evident that any number of artitions or flanges may be provided an the passages arranged in any suitable manner within the scope of the appended claims, as I struction illustrated and described.

Having thus described my. invention, 1 claim as new and desire to secure by Letters Patent: 1
