INTERNAL-COMBUSTION ENGINE;

Specification of Letters Patent.

tion engines and has for its principal object the production of asymmetrical structure and one=in which the sides of the engine casing will not be encumbered by shutting,

gearing, etc.

appear in the following specification and ac {This and further objects will more fully companyiii drawings, considered together or separate y.

, In the drawings,

. a Figure 1 is atransverse sectional view of internal combustion engine embodying my invention, provided with a rear starter d with a magneto carried on the top of the casing and inclosed by the rear starter inechanism,- the' section being taken on the lin of Fig. 2. "flag- 2 is a slde'elevation of the rear end anfingine partly in section; and

3 is a detail plan view of a portion apparatus,

the'ebove views, similar reference characters designate like parts in all the serfi res.

' It 0 drawings, 1 designates the crank which the clutc of an internal combustion engine em- 3 is a lever by means of may be manipulated and t is aprppeller shaft. The crankshaft 1 is mounted in' suitable hearings in a crank casfling of'a lower member 5 and an i'liolpedjsta upper ni'ember 6. Thecrank casing also inc and'the major portion of its operating-devices. Mounted on the top ,of themepiber'fi is a. cylinder 7, said cylinder bein usu 3 j;

- Carried entire crank shaft 1 and in proximity succumb 2 is a sprocket wheel 8.

A fsiii'ocketinion 9 is sup orted in an A '10 which is cited or othervlided with a .water jacket as is V I1 ared tothe top of the member 6, sin 11 passes over the sprockets 8 indjfi, eeham passes throu h openings 12 12 ntheftob on the r m or 6. The

merma d 10% mounted on me rear or after end of the casing and behind the real-most cylinder of the engine. The arbor 13 of the sprocket pinion J is carried inbearings in the upper part of the standard 10 and projects rearwwn'dly and its rear end carries loosely mounted thereon a hand crank 14. The arbor 13 is provided with a projection 15 which isengaged by an angle slot in the t 1 hub of the hand crank so that by movement of the crank in one direction the arbor will be rotated and the rotation of the arbor in the other direction will not move the crank. The sprocket wheels 8 and 9, chain ll and crank 14 constitute a rear starter by means of which the eiwine may be turned over by hand usually uti ized to accomplish the preliminary compression and expiosion of the casing as does the standard, and requires n additional space. g Carried on the crank shaft 1 near its connection with the clutch is a spur pinion 11' which forms the first member of a train of gearing to the magneto, as at 18, to a water circulating pump 19, as at 20, and to un'oil circulating pinup 21. as at A conductor 23 extends from the magneto 16 to a spark plug 24 on the cylinder. The

conductor is supported at intervals by means of insulatin bridge )ieces 25 and 261mg! the natural sti ness of tne wire will hold it out of contact with metallic parts of the engine. The magneto and all of the rear starter, except the crank 14, are inclosed in a casing 27 so that nonc'of the moving parts of the ap paratus will be ex oscd.

he sprocket whee S is supported in the following manner: The lower member 5 of the crank casing is provided with a partition 28'u1u1 the upper member 6 with a )artition 29. These partitions form a ulkhead through which the crank shaft 1 passes. Mounted on one side of the bulk head is an annular journal 30 which encircles the hub of the crank shaft member of the clutch 2 and on which the rocket wheel 8 is series of pawls 32 adapted to engage the teeth 31. A stop 33 is carried b the clutch member in proximity to each pawl and acts to limit themovcmcnt of the pawl against centrifugal force.

In starting the engine the sprocket wheel 8 is rotated in the clockwise direction in Fig. 1. The teeth 81 will engage such pawls as will. byrarity rest upon the hub'of the wheel and the crank shaft will be rotated to secure the initial compression 'in-the cylinders. When the explosion occurs the shaft 1 will be turned over in theisame direction and the engine will start under its own power. 'When the crank shaftis running, the centrifugal force will raise the oawls 32 from enga ent with the hub of the wheel 8 against t e stops 33 so that the soundof the awlsriding overthe ratchet teeth will bee iminated.

While]. have shown a magneto as carried on the 'casi'n 'nnd occupying the same space thereon as oes the rear starter, it will be understoodthat instead of the magneto a dynamo-for ch. 'ng a set of storage batteries may be vin the same manner..

While-I have shown'the standard 10 as A-shaped, havingtwo legs, it is to be understood t-hat's uch'standard need not neqasmrily .be so shaped noifneed it have twolegs.

-In accordance theiprovisions of the patent stututes,'I have described the principle of m invention, together with the apparatus w ich I now consider to represent the bestiembodiment thereof; but I desire to have. it understood that the apparatus shown is merely illustrative and that the invention may-bejcarried out in other Way's,

Haring now desc'ribediny invention, what I claiin'as' newfandde'sire to secm'e by Let- ,ters-PatenQ-js'; w 1,- An; internal; combustion engine having a cmnli shi ft','a crank'casing, a chain wheel Y cooperating with the shift, a manually operated ehain wheel-fcarried above the casing, a chaiji i -passingjover th'eivheelsnnd a magneto mounted on topof the casing and extendingwithintho loop ofthe chain.
