JESSE G. VINCENT, OF DETROIT, MICHIGAN, ASSIGE'OR T PACKARD MOTOR CAR COMPANY, OF DETROIT, MICHIGAN, A CORPOBATIOIN OF MICHIGAN.

:aYnnooaason-luoron.

, To all whom it may concern:

Be it known that'I, Jnssn G. VINCENT,

a citizen of the United States, and resident of Detroit, Wayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of

which the followingis a specification.

This invention ,relates I to multi-cylinder Qhydrocarbon motors, and particularly to the construction and arrangement of cylinder blocks, valve mechanism, carbureters, intake and exhaust passages, etc.

One of the objects of the invention is the construction of a 'multi-cylinder V motor so that the valves are accessible for adjust-.

I ment and for grinding, 'so that the intake and exhaust passages are conveniently and advantageously arranged relative to the valves and to each other, and so that a single passages of themotor with as little exposed carbureter may be connected to the intake p ping as possible.

' Other objects of the invention will appear "from the following description taken in connection with the drawings which form a part of this specification and in which Figure 1 is a plan view of a hydrocarbon lnotor made in accordance with this inven-' tion; Fig. 2 is a vertical section approximately on the line 22 of Fig. 1; and

Fig. 3 is' a side elevation of themotor shown in the other figures.

The invention is illustrated herein in connection with a twelve cylinder motor in which the cylinders are arranged in two blocks of six cylinders each and positioned on the crank case in V relation. Some of the features of the invention are applicable to otors having a lesser number of cylinders or to other arrangements thereof.

Referrin' to the drawing, 10 represents generally t e motor base or crank case comprising principally an upper half 11 and a lower half or oil well 12. Upon the crank blocks or castings are suitably water jack- Specifleition of Letters Patent.

eted as at 1 1, and are provided with water inlet pipes 15 and outlet pipes 16.

Each of the cylinders is provided with the usual piston 17 and a connecting rod 18 connects the piston in driving relation with Patented Dec. 25, 1917.,

the crank shaft 19 mounted in suitable bearings 20 in the crank case 10.

.Inlet and exhaust ports 21 and 22 respectively, are formed in the cylinder blocks in series along the outer sides of the blocks. One of the intake ports 21 is shown in Fig. 2 at the left side of the drawing, and one of the exhaust ports 22 is shown at the right hand side thereof. These ports of course communicate with the combustion space 23 of the cylinders and they are arranged substantially horizontally with a cap 24 screwed into the cylinder casting immediately above-each of the ports, to thus make the ports accessible for grinding and inserting the valves hereinafter described. Spark plugs 24 may be arranged in these caps 24 over the intake valves or otherwise as de sired.

Referring particularly to Fi 2 it will be observed that the intake va ves 25 and.

exhaust valves 26 are herein shown as of the poppet variety and are arranged substantially vertically and in series along the outer edges of the cylinder blockswhere they and their connections arenlost accessible: These valves of course control the intake and exhaust ports 21 and 22 and are provide'd with suitable springs 27 and push rods 28 beneath their stems. The push rods 28 are mounted in sleeves 29in extensions gears 34. These gears are shown diagrammatically in Fig. 2.

A particularly advantageous arrangement of intake and exhaust conduits or passages is shown in the-form of the invention herein illustrated. The intake ports 21, of

which there are of course six for each cylinder block, are fed by a conduit or passage 35 which extends longitudinally of each of the cylinder blocks adjacent their outer edges, or as shown particularly in,Fig. 2 these conduits 35 are arranged between the cylinders proper and the valves. In the drawings these conduits 35 are shbwn formed as an integral part of the cylinder casting. This arrangement provides suiiicient heat for the. intake gases to prevent condensation, and thereby promotes uniform firing of the cy inders.

The exhaust ports 22, of which there are also six for each of the cylinder blocks, are connected to exhaust conduits or passages 36 which arealso arranged longitudinally of the cylinder blocks and along their outer edges. As shown, these conduits 36 are formed separately and are secured to the cylinder blocks as by the bolts 37. It will be seen that the exhaust conduits are arranged parallel to the intake conduit 35, but

are outside of the valves.

The motor carbureter 38 is arranged between the cylinder blocks and is provided with a short'pipe connection 39 which connects the carbureter with conduits 40 which lead to-the intake conduits or passages 35 of the two cylinder blocks. These conduits 40 are indicated in dotted lines in Fig. 2 and are preferably formed as an integral part of the castings. The conduits 40 pass between two of the cylinders in carrying the gases from one side of the cylinder blocks to the other. a

Other forms of the invention will readily suggest themselves to one skilled in the art, and the claims are understood as not limited to the exact form of the invention shown herein.

nally of the cylinder block and arranged between the valves and the cylinder bores, and means for operating the valves.

2. In a multi-cylinder hydrocarbon motor, the combination of a cylinder block having cylinder bores and valve seats, valves for said seats, the axes of the valves and cylinder bores being at acute angles to each other, intake and exhaust conduits extending longitudinally of the cylinder block and arranged on opposite sides of said valves, and means for operating said valves.

3. In a multi-eylinder hydrocarbon motor, the combination of a cylinder block having cylinder bores and valve seats, valves for said seats, the axes of the valves and cylinder bores being at acute angles to each other, an intake conduit arranged between the valves and the cylinder bores, a carbureter on the side of the block opposite to the valves, and a conduit extending throu h the block from the carbureter to said intaie conduit.

4. In a multi-cylinder hydrocarbon motor, the combinat'io of a crank case, cylinder blocks arrangedin V'position thereon, intake conduits on the outside 'of said blocks, a carbureter between the cylinder blocks, and conduits connecting the carbureter and intake conduits.

5. Ina multi-cylinder hydrocarbon motor, the combination of a crank case, cylinder blocks arranged in V position thereon, intake conduits on the outside of said blocks, a carbureter between the cylinder blocks, and conduits passing through the cylinder blocks and connecting the carbureter and intake conduits.

6. In a multi-cylinder hydrocarbon motor,.the combination of a crank case, cylinder blocks arranged in V position thereon, and having intake ports along their outer edges, a carbureter arranged between the cylinder blocks, and conduits leading from the carbureter to the respective intake ports.

7. In a multi-cylinder hydrocarbon m0- tor,the combination of a crank case, cylinder blocks arranged in V position thereon and having integral intake passages east along their outer sides and having intakeports communicating with said passages, a carbureter arranged between said cylinder blocks, conduits connecting said carbureter with said intake passages, vertically arranged valves for said ports, cam shafts for operating said valves, and means for driving said cam shafts.

In testimony whereof I affix my signature in the presence of two witnesses.
