. I I v v I To alil ihh o m z' t may concern .1 a Be it known that I, J OHN ALLEN HEA Y,

- a citizen of the United States,'-and a resident 'ashington, in the District of Columbia, nyented certain new and useful Imements in Self-Starting Internal-Com prov bustioniEngines, of which the following is afull and clear specification, reference being had to the accompanying drawings, in wh1ch Figure l is a side'elevation partly broken away;, Fig. 2isavertical section; and, Figs;

; 3, 4 and 5;are detail transverse sections of the manually controlled valve device.

The object of this invention is toso construct the starting mechanism that it shall be built into the engine proper, thereby doing away with the unsightliness, unreliability, lack of durability, and liability to derangement which are necessarily incident to those starting mechanisms which are mere attachments to an engine.-

the pitmen connecting the pistons to" the main crank-shaft d, all constructed in substantially the usual manner.-

diameter than themain piston and working I in a supplemental cylinder f formed as a dapted to be reciprocated by means of a .'cated near the upper extremity .of the sup-- continuation of the main cylinder, Work ing between each supplemental piston and its cylinder is a valve-sleeve g WlllCll 1s valve-rod h connected to an eccentric 2' on the crank-shaft.

Each valve-sleeve is provided at dia- .metrically opposite points with ports j and 7c and these ports are adapted to register respectively with cylinder ports Z and m loplemental cylinder. The ports Z are all located onthesame side of the cyllnders and 'they all communicate wit-ha pipe ormanifold-"m'whileiports'mare all on the opposite sides of the cylinders of the engine and are all in constant communication with a similar pipe or manifold o.- i

The pipes n and 0 are at their ends con- Specification of Letters Patent. Application filed April 5, 1912. Serial no. 688,634.

Mid-way the pipes n and 0 the valve casing 79 is provided at one side with an atmosphere-port s and at the other side with a port I a pipe 25 with an air-storage tank u.

which is connected by means of It will be observed thaflwhile the engine is running under fuel power, the valve-q case the supplemental pistons will act as air pumps, drawing air in through port 8, pipe is andexpelling theair 1 0, ports m, and'ports through-{ports a nd-Z,"pipes n and t, and

'will be adjusted as shown in Fig. 3, in which a I tank, thus nullifying the pumping action.

The engine Will then continue to run against the pressure of the air which is entrapped in the supplemental cylinders and the connect ed ports and pipes, and thislentrapping of the air-in the cylinders serves to cushion the upward 'strokes of the working. pistons,

decreasing the Wear and thereby materially noise of the operation of the engine.

lVith the desired pressure in the tank, to start the engine. it is simply necessary to turn the valve. plug in Fig, 5 in which position the pipe n will be open to the atmosphere and the pipe 0 will be placed in communication with the I tank through the pipe 5, whereupon the come pressed air will be admitted to that cylinder or cylinders whose ports is are in register with ports m. This will cause the supplemental pistons and cylinders to act asa mog to theposition shown tor in starting the engine. Of course it will be understood that the cylinder arrangement of the engine and'the'arrangementof ports is andm will be such'that-at all times there will be at least one pair of ports is and'm in register; in the twin-cylinder type of fourcycle engine I have shown'there will at all times be at least two pairs of ports is and 'm in register so that. 'upon the admission of. compressed air into pipe 0 there will be at least two supplemental pistons available as .motor pistons, thus assuring an effective starting of-theengine under the-most adversefconditions.

'It will be further observed that thervalve -'or controlling means may be greatlyvaried without departing from'the spirit of my inventlon; In itsbroad aspects, my invention contemplatesthe employment between "the work piston and the crankeshaft of a'supiplemental piston of a larger diameter than the 'work piston, together with automatic or as a' motor piston, suitvidedfor manually bringingabout the conversion; and a suitable storage tank for the compressed air-being provided. .a 1 "Having thus -r-ul1 described my invention,-
