. ENGINE-COOLING DEVICE.
To all whom t may concern .I
Be it known that' I, JOHN DESMOND, a icitizen of the United States, residing at Chi-` 'cago, in the county of Cook and State of Specification of Letters Patent.
Application filed August 8,
, Patented Mayet, 1912. 1910.' serial No. 576,035.
conduits`l0. The conventional exhaustvalve. '11 `with valve stem 15 .and beam 1G are shown mounted upon the head casting with the exhaust pipe leading through the hol- Illinois, have invented certain new and uselow head chamber 13 to be surrouiuledby ful Improvements in Engine-Cooling Dc-v viccs, ofiwhich the following is alspecification.
My invention' relates to improvements in i provide a construction lof cooling device of the character described vinvolving a minimum number of castings, each cheaply made characters indicate similar parts.
' 5 is a conventional representation of a cylinder casting of an engine provided with a piston, G, and a connecting rod, 7. Inthe ,40 outside surface of the cylinder 'are radially projecting ribs, S), which are integrally formed with the cylinder wall, andextend vertically and parallel with the axis of the cylinder to provide therebetween channels or air conduits, 10. 'Around the ribs, 9, I
place a cylindrical casing, 11, which may be an integral part of the cylinder or which is preferably separable and made of relatively thin sheet iron and this casing incloses the 50 channels between adjacent ribs and forms' independent conduits thereof. I y provide a separable cylinder head casting 12, such asshown in the drawing, having a hollow part 18 which communicates through 55 itsbottom wall with each Aand all of the Thesalient object of my invention is to' the airdraftin said chamber. To the part 1T of the exhaustA valve, I connectl a pipe 18 through which to convey the burned products of combustion.
Vtracted near its middle lto increase the velocity of lthe-passing gases, and then it is taperingly increased in diameter to its end to'givetapering form to the outgoing gases,
ing 2G of the casing 20, may be connected to a subsidiary inufl'ler by a. pipe or the exengine cooling devices and more particn- An ejector, 19,' comprises,preferably, a 65 -larly to an improved forni of cooling strucspherical shell, 20, to which is connected an ture wherein the energy of the escaping air pipe, 21, the latter being also connected products of con'ibus'tion is vused to induce an to the hollow cylinder hea-d, 12. Itwill be air current to pass 'around the heated engine,K observed that Aa nozzle, 22, is connected to parts. the end of the pipe 18. It is slightly con- 70 2@ and durable in use, which maybe easily :isthat they may substantially fill the smaller 75 sembled and maintained in association with ind of the combining cone-tube, 28. The a suitable ejector, to provide an engine struc' 'cone-tube, 23, is spacedapart from the simiture in which not only the cylinder Walls lar tube 24,each being secured to the shell` are`kept cool but the pipe leading iminedi- '20, by fastening devices 231 and 24', respecl ately from the exhaust valve is cooled by tively. Tube, 24, is spaced apart from tube 80 being entirely surrounded by air draft' 25, the latter beingO shown as an integral which passes through a. hollow headcasting part of the casing. forming part of the device. There may be as many of the combining In the drawings, wherein I have shown tubes, such as 23, 24, 25, etc., as desired my improved st-ructure, Iigure 1 is a Cenwithin the casing. vI have attained most ex- 85 `tral longitudinal SQCOII 0f. Ml'ellglle Cylncellent results from. a structure in all essen der with my cooling device attached thereto; tial respects such as illustrated in the draw F ig. 2 is a cross sectional view taken 0n ing, but, of course, any ejector operating line 2 2 of F ig. 1; and like the one above described mav be used as In both of the views the same reference a part of my improved structure. The open- 90 haust may escape therefrom directly into the atmosphere.
The ejector device, besides inducing active circulation of air around the heated engine parts also serves as a inutiler to some ext-eut and may be extended so as toentirely displace multlers of the usual-type.
The arrows show the direct-ion ofthe exhaust gases through the ejector. The arrows also show the direction of air currents induced by the exhaust the eectolr device.
The oprtion of the device is so apparent as not to require'fnrther or extended'dcscription.
AIt will be observed that :the structure which I have described is capable of cheap manufacture, easy assemblage and maintegases passing through nance, and efficient operation, owingttlic pipe integra] with saidhead casting and correlation of the several castings and apleading from the bottom to the side thereof pui'tenant parts, and I- therefore limit my.- through the head-'eliainben'a suitable 'valve lself onlyto such structure which utilizes the and valve operatingnieans associatedwith novel correlation of parts, though otherwise said exhaust pipe, an air exhaust openingin l .l changed in unessential details, not specithe opposite side of said head, an Iejector callyY recited in the following claim. providing an inlet andan outlet iforl the What Iclaim's:v products 'of combustion from said cylinder I In a device ofthe character described, an andan inlet for air, means whereby 'current engineJ cylinder casting providing a central between said inlet and outlet forprodiicts piston-receiving chamber open at both ends of combustion induces flow of ai'r through andpifoviding upon its outer surface a said airinlet, and suitable pipingconnections plurality of integral ribs extending frombetween said air outlets of the ead casting."
