v nature of my improvements, and

E-1-4- em VALVE COOLING MEANS FOR INTERNAL- COMBUSTION ENGINES August r. w. Helmboid, Augusta, Ga. Application January 11-, ism-semi No. euros rcmm. (Cl. 123-177) My invention relates to valve cooling means for gines, the primary object in view being to equip the usual internal combustion engines with inexpensive and simply constructed means for causing the in-coming intake gas in the valve cham-.
bars to cool the exhaust valves before such gas is ignited.
' other and subordinate objects, also comprehended by my invention, together with the precise the manifold advantages thereof, wfll be readily understood when the succeeding description and claim are read with reference to the drawings accompanying and forming part of this specification.
In said drawings:
Figure l. is a view vention .applied, in thereof, s
Figure 2 is a view in side elevation,
Figure 3 is a view in vertical section taken the line i& of Figure 1,
Figure 4- is a view in plan of the deflector bafie,
Figure 5 is a view in side elevation of the same,
Figure 6 is a view in side elevation of the exhaust valve, and
Figure 7 is a view similar to Figure 3 of a modification of the invention.
Referring to the drawings by numerals, and first toFigures 1 to 6 thereof, my invention has been shown therein, in a preferred embodiment engine embodying a single cylinder forming block i capped by a cylinder head 2 forming with said block I the valve chamber t opening into a combustion chamber 0. The usual pair of intake I5, 6 are mounted, as shown, in the block I alongside the cylinder i.
According to my invention, an upstanding, horizontally elongated, and generally rectangular deflector bafle 8 in the form of a fin of uniform height and thickness, preferably, is provided in the valve chamber 3 and on the block I between the pair of valves 5, 8 bet 4 to deflect incoming gas, admitted by the intake valve 5, toward and over the exhaust valve c is closed. The baflle deflector 8 may, as shown, be cast with the block i. As best shown in Figure 1, the deflector baflle 8 extends generally crosswise of both valves 5, B and is formed opposite the intake valve 6 with a major portion 8 curved in a long are away from said intake valve 5. the portion 8 merging with in plan illustrating my ina preferred embodiment a shorter end portion l0 tive to the portion 8 and terminating close to the perimeter of the exhaust valve 6.
In addition to the foregoing, my invention comprehends providing the exhaust valve 0 with upstanding teats ll tending to facilitate rapid transfer of heat from said valve and thereby contribute toward cooling the same,- and whichalso act as cooling fins on said valve between and around which the cool deflected intake gas may In the modification illustrated in Figure 7, the. deflecting baiile l2 depends from the cylinder head it. Otherwise the construction and arrangement is the same as that previously described. 1
As shown in the drawings, the deflector baiile B is spaced slightly from the cylinder head 2, and the deflector baflle I2 is simiarly spaced from the block ii. This spacing may be varied, or eliminated, as may be found suitable in difl'erent oppositely curved relatypes of internal combustion engines. of the engine, the cool intake In the operation gas admitted by the intake valve I into the valve and exhaust poppet valves and the combustion chamchamber 3 is deflected by the baille deflector I to pass over the closed exhaust valve 6 and between and around the teats ll. 'Thus the top of the exhaust valve 6 is cooled, the teats ll tending to transfer heat from said exhaust valve 6 to the cooler intake gas. valve 5 advantageously supplements the usual cooling of the same through contact with the cooled valve seat.
The foregoing will, it is believed, sufllce to impart a clear understanding of my invention, withp out further explanation.
Manifestly, the invention, as described, is susceptible of modification without departing from the inventive served to such modifications asfall within the scope of the appended claim.
What I claim is: a
In an internal combustion engine embodying a valve chamberhaving a pair of intake and exhaust poppet valves therein for admitting gas into said chamber and exhausting the same therefrom, respectively, deflecting means in said chamber for causing the gas admitted by said intake valve to pass over said exhaust valve to cool the same, and cooling studs on said exhaust valve through and around which the deflected gas may pass, said deflecting means comprising an elongated deflector baflie extending alongside said pair of valves and comprising a major portion curving part way around the intake valve for This cooling of the exhaust acollectlfi'x as and termlnatinl in an op omm l curved qnnor portion opposite-the exhaust valve. .1,21'8,565 I AUGUST 1.
