Specification of Letters Patent. Patented July 30, 1912.

Application filed November 9, 1911". Serial No. 659,331.

To all whom it may concern:

Be .it known that LGEoRGnE'. MILL R, a citizen of the United States, residing at Oakland, in the county of Alameda and :State of California, have invented new and useful" Improvements in Gas-Engine Start ers, of which the following is a specification. This invention relates to starting appairatus for internal combustion engines.

.Theflobject of the present invention isto provide a starting apparatus'for internal combustion engines, such apparatus involving. one or more gas retaining chambers which may be suitably attached to or formerlwith aportion of thecylinder. or of each of "the cylinders of the motor.

It is well known that the combustible gases utilized fort-he operation of internal l combustion engines'will retain their inflammable proper-ty for a considerable time after generation, audit is the object'of the present invention to so arrange a serles of recep 'tacles or containers, in which'may be accumulat'ed a charge ofinfiamm able' or ex plosive gas derived from the generating sysam of the motor-when the latter is running,

a practicable apparatus for the reserve ofa and which stored charge of gas may be utilized at a later'time for the initial startingot-the engine, thereby avoiding crank- I 'The invention consists of the parts and the construction and combination of parts, as terelnafter more claimed, having reference to the accompany fully described and 'ing drawings, in which I Figure 1 is a side elevation of a fourcylinder motor, showing the apparatus at- .tached. Fig. 2 is a detail view of one of 40 mechanism.

the compression chambers with its valve- I Fig. shows the valve in charging position. 'Fig. 4 shows thevalve inclosed position. Fig. 5 is a longitudinal section of the valve.

It is a desideratum to.devise and provide charge of. compressible gas, which charge maybe derived from the enginegenerator, inthe present instance, just before, the en-.

gine ceases. operation and after the sparking system has been rendered inoperative. Ordinarily engines of this type will make afew revolutions after the spark has been cut out and this continued motion of the engine results in the pumping of a pure and unexploded charge ofgas'into one or more of the cylinders of the engine. The presentinvention is designed to reserve a portion of this fresh, unexploded gas which is drawn into the engine by its revolution after the spark has been cutout. To that end I provide one or more chambers, as 2, of suitable proportion, which maybe formed with, or connected to, one or more of the cylinders of the engine A.

tion I havejshown the chambers 2 as 'connected to the cylinders of the engine by a valve body 3, in which is movable a valve plug-4 which is provided with a port- 5 adapted to be turned into alinement with the central channel. 6 of the valve body 3.

In the upper end of the valve there is prosided an automatically seatable puppet valve'7, which' is seated in the present ins'tance by an expansible spring 8.

The valve plug 4 is normally turned to the cut off position by'means of the connecting rod 9, which may be connected with each of the levers 10 of the valve plugs. During the running of the motor the connecting rod 9 is shifted to such a position inoperative results in the charging of one or more of the engine cylinders with fresh Themomentum of the moving parts 01 the engine will compress the gas in the cylinder and-the operator, when desiring to charge the reservoir chambersQ, shifts the connecting link 9 so as to move the valves 4 to 'open the channel 5 and permit aportion of the gases to be" charged or compressed in the chambers 52. At each impulse or compressionof gas the puppet valves 7 will'litt to permit the gas'to accummulate in its respective'ch'amber2 and immediately seat, thus holding the charge of gas. The

operator will permit the valves 4 to remain in open position for a sufficient length of time to enable vthe chambers 2 tube charged and will then shift the connecting rod 9 tov again close the valves 4-. Since each of the storage chambers 2 is now charged with a 1 c5- In'the present embodiment of the lnvcnvolume of pure explosive gas which it is well known may be retalned 1n explosive condition for a considerable length of time,-

when the operator wishes to start the motor,

he shifts the connecting rod 9 to turn the valves 4 soas to carry a cam 11, of which there is one on each valve, into lifting engagement with the stem of the puppet valve 7. This mechanical movement results in the lifting of the puppet valves 7 from their seats and allows the compressed explosive charge in the chambers 2 to escape into the engine cylinders, when the connecting rod 9 nectionsbetween said chamber and a combustion cylinder of themotor, an automatic valveinterposed between said chamber and said cylinder, and a valve operable to open communication between the cylinder and the reservoir chamber to allow..the latter to be charged, said last named valve having a cam surface and the automatic valve having a part disposed in the range of action of said cam surface and adarted to be lifted thereby.

2. The combination with an internalcombustion motor, of a reservoir chamber, connections between said chamber and a combustion cylinder of the motor, an automatic valve interposed between said chamber and said cylinder, a valve operable to open communication bet-ween the cylinder and the reservoir chamber to allow the latter to be charged, and means for opening the automatic valve to allow the compressed gas to escape-into the cylinder of the motor, said means including a rotatable cam on the second named valve, and said automatic valve having a stem to be engaged and lifted by said cam.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
