STARTER FOR INTERNAL-coranusrion ENGINES'.

Specification of Letters Patent. Application filed January 7,'1914.

'Patenten sept. sa, inra. Seri/31H0. 810,318.

To all lwhom 'it may concern 1 Be it known that I, SIMON S. SUTTON, a citizen of the United States, residing at Eldorado, in the county of Saline and State llinois, have invented new and useful Improvements in Starters for Internal-Combustion Engines, of which the following is a specification.

This invention relates to starters for inengines, the object in view being to provide simple, economical and reliable means whereby compressed air stored in a suitable tank by the operation of the engine itself is subsequently used in connection with a priming tube and properly arranged stop-cocks Aand a check valve con trolled by-pass, to prime the combustion chamber of the engi-ne cylinder with eX- under the requisite com pression to produce a. full and powerful im- 'pulse on the piston When ignited by the usual spark device.`

` With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts.

' as will hereinafter be more fully described,

length, one end of cylinder so as to discharge into the combuse' illustrated and claimed.

" The accompanying drawing represents a side elevation showing the starting means of this invention applied to an internal combustion engine which 1s conventlonally f shown. y

Referring to the drawing- A generally designates an internal combustion engine which is conventionally shown as comprising a cylcates.

In carrying out the present inventio-n I provide a priming tube l of any suitable which is connected to the tion 'chamber of said cylinder, the discharge end of said pipe being controlled by a stop cock 2. At the opposite or filling end of priming tube l, I place a having its own stop-cock 4. 2 and 4 thus serve to priming tube 1.

5 designates a compressedair tank having priming cup 3 a capacity equal to or greater than the comcylinder so that a bustion phamber-of the may be compressed sufficient amount of air in said tank to charge the combustion chamberv of the engine With a pressure equal to the ordinary operatlng compression of said lnder B in Which the usual piston recipro- The stop-cocks close both ends of the 'l engine. From the tank 5 an air pipe leads to the priming tube l with which it communicates between the stop-cocks 2 and l. A by-pass connects the airytube 6 with the priming. tube l and communicates with said priming' tube between vthe stop-cocks 2 and fl. The by-pass 7' is provided with a check valve S to prevent back pressure from the tank 5 reaching the priming tube l and combustion chamber of the engine. A stop-cock j t) is arranged in the air pipe 6 between the I priming tube l and the junction of the air l f tube 6 and by-pass Another stop-cock 10 is arranged in the air pipe t5 between the compressed air tank 5 and the junction of the air pipeand by-pass 7.

.- The operation of the starting means here inabove described is as follows. When the l engine is to be stopped, the fuel supply is first cut off thereby terminating the eXplosions and preventin any further admission Oflgas to the cylin er. At the same time, l the stop-cocks 2 and l0 are opened and while j the engine is still turning over, thepiston 5 acts as anair compressor forcing air past I the check valve 8 into the tank 5. In order Il to prevent any possible leakage of the coml pressed air in the tank 5, the stop-cock l0 l may then be closed.

en it is desired to start the engine, a suitable amount of gasolene or other liquid fuel is introduced through the priming f 3 into twhe priming tube l and the stop-cock i 4 closed, thus trapping said fuel in the prim- .l ing tube. The stop-cocks 9 and l0 are then opened so that the ycompressed air is deliveredinto the priming tube l behind the liquid fuel conta-ined therein. 2 is then opened and the fuel is forced quickly by the vconljn'essed air into the combustion chamber. rJhus ture under full engine compression is adi' mittcd into the combustion chamber and the piston being set just over or past the center, y the stop-cock 2 is then closed and the compressed charge of gas is ignited by the usual ignition device which may, if desired, be 'tripped by hand or by turning over the l wheel of the engine. rlhereupon a full impulse is given to the piston and while the yengine is turning over, the ordinary fuel supply may be opened whereupon the engine l will take up its Own cycle of operation.

f If desired, a spray tube 1l may be placed i at the discharge end of the priming tube l r l i The stop-cock and Within the combustion chamber so as to atomize and thoroughly distribute the eX- plosive mixture throughout the combustion chamber, said tube being shown as formed with a large number of pei-forations 12 through which the explosive mixture is ex- What I claim is 1. A starter for internal combustion engines, comprising a priming tube arranged to discharge into the combustion chamber of the engine, a priming cup on t-he iilliiig end o said tube provided with a stop-cock, a stop-cock controlling the discharge end oi". said tube, a Compressed air tank, an air pipe leading 'from said tank into Said prilning tube between the primingI cup cock and the i dischi-ige end cock, a b y-pasfs'leading rom said air pipe into said priming tube between the priming cup cock and discharge end cock, a check iali'e in said bie-pass, and a stepcock controlling said air pipe and located between the priming tube and the -junction of the air pipe and by-pass.

2. A starter for internal combustion engines, comprisin0'\'a priming tube arranged to discharge into the combustion chamber of the engine, a priming cup on the filling end of said tube pro-vided with a stop-cock a stop-cockv controlling the discharge end eti said tube, a `compressed air tank, an air pi-v' leading from said tank into said priming tube between the priming cup cock and the discharge end cock, a bj) -pass leading from said air pipe into said priming tube between the priming cup cock and discharge end cock, a check valve in said bypass, al etc-ir cock controlling said air pipe and located between the priming tube and the vjunction oit the air pipeaud by-pass, and another stop-cock between the tank and junction oi' the air pipe and ley-pass.
