f1.Y In an internalcombustion engine, the combination Vof a depending cylinder head having an upstanding inner wall, said wall forming `with the head outer wall an an# nular cooling spac.ea tubular member surrounding said'inner wall in spaced relation thereto, said tubular member having its lower end open and inl communication with the cooling space, and means for introducing water between said member and the inner A.wall ofthe head.

V.2..InV an internal combustionvengine, the combination of a depending head having an annular water space therein, a tubular memberk secured toV said head vertically dividing said V,Wat'erspace, said tubular member having its bottom end open, and means forming an opening through said tubular member adjacent the upper .end thereof. j

3. In an 'internal combustionengine, the combination of a depending head having an annular -water space, a tubular partition eX- tending downwardly within said space in spaced relation to both inner and outer walls thereof whereby said space is divided into yannular passageways, means forming communication between said passageways adjacent the bottom of the annular space, and means for introducing Vwater within one of isaid passage ways.

4. In an internal combustion lengine the. combination of a depending cylinder'head having inner and outer walls forming an annular water space, a vertical tubular partition, within'said space'terminating adjacent the bottom thereof, means for introducing water on one side of said partition, and means for causing the water on one side of the partition to flow' downwardly toward the bottom of said annular space.

511In an internal combustion engine, the combination of a depending cylinder head having inner and outer tubular walls forming an annular water space therebetween, a'

tubular partition intermediate said walls in 'y' spaced relationy thereto, means forming a passagewayv between opposite sides of the partition at the lower end thereof, means forming a passageway through the partition atthe upper end thereof, and means for causing water to flow through one passageway and along one side of the partition in one direction, and along the other side of the partition in the opposite direction.

6. In an internal combustion engine the combination of a depending cylinder head having inner and router,A walls forming an annular water space within the head, a tubular v'deflector forming a vertical partition within said annular space, said deiiector having an inturned flange at its upper end in contact with the inner walls of the head, the lower portion of said deflector being spaced from both the inner and outer walls of the head, means forming a communication between opposite sides of said deiector adjacent the bottom of the space, and means forming a waterconduit in communication with the interior ofsaiddeflector below the inturned flange. Y Y Y 7 In anrmternal combustion engine the combination 'of a depending cylinder headv having concentric inner and outer walls forming anan-nular water space, a tubular deflector surrounding the inner lwalls in spaced relationV thereto and projecting down within the space adjacent the bottom thereof,

means forming a closure between the deflector and the vinner wall, Ameans forming a water conduit to the space between the deflector and inner wall, and means forming a passage between opposite sides Yof said deliector adjaf cent the bottom of the water space.

8.'In an'internal combustion engine, combination of a cylinder having a water jacket, a cylinder head closing'the upper end circling said .extension in spaced relation' thereto, and means for producingwater fiow between saiddetlector and extension.

9. -In an internal combustion engine, the'- combination Iof acylinder having a water jacket, al cylinder head closing thevupper end of said cylinder,a cover over said cylinder and head enclosing a water` space in communication with the water'jacket, said 7 head having outerV walls and `a tubular eX- tensionV projecting'fupwardly through said cover, said extensionv forming with the side walls an annular water space, ai tubular deiiector encircling said extension in spaced TIL relation thereto, means forming a closure for the upper end of the space between the deflector and extension, said deflector having its lower end -open,' and'y means forV directing water through the deflector adjacent the upper endthereof. i

10. In an internal combustion engine, the combination of al cylinder having a water jacket, a cylinder head closing-the upper end of said cylinder, a` cover Vover said cylinder the 'and head enclosing a Water space in communication with the water jacket, said head having outer Walls and a tubular extension projecting upwardly through said cover, said extension forming with the side walls an annular water space1 a tubular deflector encircling said extension in spaced relation thereto, means forming a closure for the upper end of the space between the defiector and extension, said deector having its lower end open, and means comprising a conduit passing through the cover for directing water through the delector adjacent the upper end Y thereof.

In testimony whereof, I aiix my signature.

WALTER S. FISHER.
