haveinvented certain new and useful Improvements in Hydrocarbon Motors, of

which the following is a specification.

"This-application is a division of application Serial No. 838,623, filed May 11, 1914.

This invention relates to hydrocarbon motors,and particularly to multi-cylinder mo- 'tors. One embodiment of the invention is shown and ln-cludes a SIX cylinder motor 1n which there are two block castings ofthree cylinders each mounted. on a suitable base or crank case.

One of the objects of the invention is to produce a multi-cylinder motor of clean external appearance and one in which various parts of the motor are housed or inclosed.

Another object of the invention is to improve the water circulation system through the various aclrets of the motor, carbureter, etc.

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 l is a side elevation and vertical sectional view of a motor embodying this in-- vention;

Fig. 52 is a plan view of the motor shown in Fig. 1;

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1 with certain of the cylinder heads and. valve sleeves omitted; and

Fig. 4.- is a view similar to Fig. 1. illustrating a slightly diliercnt form of the invention.

In the embodiment oi the invention shown herein, the motor comprises six cylinders cast in two blocks of three cylinders each. It will be understood that a lesser or greater number of cylinders may be employed and the cylinders may be otherwise cast.

Referring to the drawings, the base or crank case 10 is formed in two parts, the upper or supporting part 11 and the lower part or bottom cover 12. The cylinder blocks or castings are shown at 13. there being three cylinders lei to each casting.

The up er end of each of the cylinders '14 is somewliat contracted, as shown particu- Specification of Letters Patent. Pat-rented J Divided and this application lgebi'iiary larly in Fig. 1 forming a dome-shaped Yeombustlon space 20 immediately above thefupiper limit of travel of the piston ifij This contracted part of the cylinder isdouble walled and is of outward cylindrical form and constitutes a Water-jacketed head'for the cylinder. In it are arranged suitable inlet ports 22 and exhaust ports 23, preferably arranged in the same zone and both ofwhich are adapted to be controlled by a cylindrical or sleeve valve 24:. For the purpose oi'getting a more perfect fit for the valve 24, it is sometimes desirable to place a lining sleeve or collar 25 on the outside of the head 21 said lining sleeve of course being provided with inlet and exhaust ports alining with the ports 22 and 23-formed in the cylinder head. .1 Q The cylinder head 21 also provided/with a centre]. depressionor cavity 26 in which a spark plug 27 is suitably arranged in"c'ommunication with the interior of the cylinder or combustion space 520. Thecentral ter1ninal 28 of the spark plug extendsflcbove the top of the cylinder head and the cavity 26 is closed by a suitable cap 290i insulating material. i;

It will be seen that thecylinder. i i-are water-jacketed as at '30 a'ndth'is jacketing.

space continues up into the head 21. Water i is supplied for cooling purposes by a pump 31 operated by suitable connections from the motor crank shaft through pipes and 33, to the lower part of each of" thc 'cylinder castings 13, as shown particularly; in Fig. 1. There is a water outlet from each oftlie heads 21 as shown at 3.4: in Fig. 15' and to all of these outlets is connected a pipe 35 which runs across the top of the'cylinders and coin nects with a suitable radiator, not shown in the motor "tion therefor of a pipe 13, part 0 gether on the tops of the cylinders and form a compact arrangement thereon.

It will be understood that a suitable cylindrical space is left between the exterior of each ofthe cylinder heads 21 and the interior walls of the head pieces 37, to form a valve chamber in whichthe valve 24 operates, being rotatated by suitable mechanism to control the inlet and exhaust ports.

Means are provided for supplying cooling water to the head pieces 37, either from the pump 31 as shown in Fig. 1 in full lines, or by an entirel separate circulation system which woul include a slight modification of the pipin arrangement shown in Fig. 1, such as s own in Fig. 4. In the drawings, the jackets of the various head pieces 37 are connected in series by short sections of pipe 39 (see Figs. 1 and 4. and in Fig. 1 apipe 40 leads. from the pipe 33 to the lower part of the head piece 37 of cylinder number 1, and an outlet pipe l1 leads from the upper part ofthe head piece 37 of cylinder number 6 to the water-jacketed part 42 of the carbureter 43. Also a pipe '44. leads from the lower part of the carbureter water jacket to the water jacket of one of the cylinder castings 13. As above suggested, a modified form of this system is shown in Fig. 4 and nation of pipes 44 and 40 and the substitu- 45 extending from the lower part of the carbureter jacket 42 to the head piece 37 of cylinder number 1. By the-latter arrangement, there is a constant circulation of water serially through the various headpieces, and'from head piece number 6 through the pipe 41 and car bureter water jacket 42 and from there through the pipe 45 back again to head piece number 1. Thus the cooling action of the carbureter 4.3 acts as a radiator for the heated water from the head pieces, while on the other hand the hot water passing through the Water jacket of the carbureter assists materially in vaporization of the gasolene. This arrangement of piping gives an entirely separate water circulation independently through said head pieces comprises the 'elimieach cylinder having water jackets separate from the cylinder "water jackets, oi means for circulating water tl'ircugh ali of said head pieces in series.

4. In a hydrocarbon motor, the combine. tion with a plurality of watenjacketed cylinders and separate water jacketed head pieces for each cylinder, of means for circulating water through said head pieces independently of the cylinders.

5. In a hydrocarbon motor, the combination with a plurality of water-jacketed cylinders and separate water jacketed head pieces for each cylinder, of means for circulating Water through said cyiinders by forcing it in 'top thereof and for independently circulatsystem for the head pieces and carbureter.

\Vith the system shown in Fig. 1, the water pumped into the pipe 33 is divided therein, part of it oing to the rear cylinder castingit to the front cylinder 13 and some of it to the head pieces 37 through the pipe 40. Of course the heat in the cylinder water jackets and the head pieces assists materially in the circulation of the water throng them.
