Be it known that I, \VA-LTER 1V. Mackenf ni sw'. a 'citizeirofthelnited States, residing at Pittsburgh, inth'e county of Allegheny,
State of Pennsylvania,- have invented cer- -tain new and" uset'ul l mproveiii'ents in Cooling 'Means for Gaslin'gine Cylinders, of
- qwhich the tollowingis a specification.
My invention relates to means for cooling adapted for-automobile engines. The ob ects-oi my invention are: 1. To
gas engine cylinders and is particularly I provide eliicient cooling means integral with i xthe'engineiand thus to'dispense with a radi- 2. To provide means.

To 0001- the water in the jacket by means of the; surrounding air and to use a-m'etal for the jacket such as copper p havinga highconductivity for heat. 5. .To

'Toincrease the radiating etlectof the jacketby corrugation and f to further increase it byexterior fins. '7. To l 39 provide means for indicating an excessive temperature in the jacket. 7
Referring to the drawingsFigure 1 is diagrammatic sectional p'lan'of a 1- cylin'der engine equipped. with my: invention.
I .Fig'. 2, is a vertical section through one cyl- 'inder thereof and Figs. 3 l and 5 are detail the jacket.
As this invention is applicable to either two or four cycle engines wita various arrangement of valves and shapes of cylinders, no valves have been shown in the drawings it beirig understood that it is well within the skill of the designer to adapt my invention to the details of the cylinder to be cooled.
The cylinders 1 may be cast en M00 as shown or in any desired manner. The sheet metal jacket 2 may inclose all the cylinders as shown or a separate jacket may be provided for each cylinder. The jacket 2 is preferably made of thin sheet copper bent views of different forms ofcorrugations for or corrugatedin any one of various forms and, closely spaced.

rugations being to split up the water into thin streams and to increase the exterior surface of the jacket they should be deep To still further increase the conduction andradiation of heat from the jacket I provide serrated projecting ribs or fins? which may be either integral with the jacket or attached thereto as by riveting or soldering. While both the corrugations 3 and fins 6 may be horizontal or inclined, it is preferable to make them vertical, thus being parallel to the flow of both water and air currents.
Referring to Fig. 2 the jacket 2 extends from top to'bottom of the cylinder or as far up and down 'as convenient. according to the design of cylinder. The jacket 2 is provided with a tightcover 7 and arfiller cap 8. A pipe 9 may be led, to the dash to indicate boiling of the water by the escape of the steam. A bafile plate 10 extends vertically froni near the bottom of the jacket to near the top of the same and surrounds the cylinder or cylinders leaving aspace' above and below for, the passage of the water from one side of the plate 10 to the other. The plate 10 is fastened to small lugs 11' on the cylinders. In'action the he'atedwater in the space 12 between the cylinder walls and the battle plate 10 rises I and passes over the upper edge of the plate to the space 13 between the plate 10 and the jacket 3. The space 13 communicates with the numerous small spaces 1 inclosed byv the corrugations 3 and the water is thus subdivided into thin streams which are quickly cooled.
By the above arrangement a continuous rapid unimpeded circulation is maintained in the jacket 3 as long as there is any heat generated in the cylinder.
It will be understood that the jacket 3 is to be designedto suit the size and temperature-of the cylinders to be cooled and it will be seen that that with proper design the jacket can be made so the engine can never overheat even in warm climates and this can be tested experimentally by running the engine under full load in a'clos'ed box the air in which is maintained at the maximum temperature of the climate.
i It will be apparent that instead of using corrugations in the jacket for subdividing the downwardly moving stream of water the same effect could be obtained by using partition within the. jacket lying between a number of small tubes of round, square or fiat section but thiswouldvmerely increase the cost of manufacture without adding materially to the efficiency of the apparatus.
From the above it will be seen that I' have provided a simple and efiicient apparatus for cooling gasengine cylinders which dispenseswith the radiator, piping andpump usually employed on automobile engines and-have the exterior of the cylinder and the inner surfaces of the corrugations, said partition having a length less than the length of the jacket leaving-a passage way at each end thereof whereby the heated inner space next. to the oyhnder produces an ascending current, and the surface of the corrugations with exterior vertical cool the same and cause it to descend thus maintaining a constant circulation inthe jacket to cool the cylinder.
2, A gas engine cylinder and cooling means therefor, comprising a water jacket surrounding the cylinder, and provided partition within the jacket lying between the exterior of the cylinder and the inner surfaces of the corrugations, said partition having a length less than the length of the jacket, and spaced from the upper and lower surfaces of-the jacket forming communicating' water spaces,"and the contour of said partition on a section parallel to the cylinder and at a rightangle to the shaft being curved to substantial parallelism with the exterior of the cylinder.
3. A gas engine cylinder and cooling means therefor, comprising a Water acket corrugations, and a communicating water-spaces.
In testimony whereof I hereunto aflix my surrounding the cylindenan inner space in said jacket through which the water flowsupwardly, and an outer space in said jacket through whichthe waterfiows downwardly, said outer space being subdivided so the water is subdivided into a number of thin streams, and a vertical'partition' between the inner and outer spaces and within the jacket, 1 and spaced from the upper and lower surfaces of the jacket forming communicating water spaces.
4. Cooling means for gas engine cylinder, comprisingip, water jacket provided with vertical corrugations, vertical fins on the outside of some of the said corrugations and a vertical partition within the jacket dividing the same into .inner and outer spaces, and spaced from the upper and lower surfaces of thejacket forming communicatin water surfaces.
0. A gas engine-cylinder and cooling means therefor, comprising a corrugated sheet metal acket, a flange on the cylinder below the jacket, a cap above the jacket the same being secured to the cylinder and a.
partition within the jacket separating the water space into inner-and outer portions,
and spaced from the upper and lower surfaces of the jacket "forming connnunicating water spaces. i
6. A plurality of gas'engine cylinders and cooling means therefor, comprising a water jacket inclosing more than one of the cylinders and provided with vertical corrugations, and a partition withinthe jacket parallel to the contour of the jacket and of a 3 less length whereby the water spaced is divicled into inner and outer portions and a thorough circulation of the water is induced,
said partition being spaced from the upper and lower surfaces of the jacket forming.
