INTERNAL-COMBUSTION ENGINE.

To all whom it may concern Be it known that LjHENRYA. chaos, a-

Jcitizen of the United States, residing atSt.

Joseph, in the county of Buchanan and State of Missouri, have" invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification, reference being had therein to the accompanying drawing. y I

My invention relates to improvements in internal combustion engines, and the objects of my improvements are, firstrto provide a a I I f fuel ntake 14, (see Fig. 1,)- which latter ris providedwithvalve 15, which valveis simple, substantial and l durable engine, 0

this class, which shall. be of the: two cycle type, second: to soconstruct and arrange the parts of an internal combustion:engine,:that practically all ofthe products of combustion shall be expelled'there from at each and every return stroke of the pistons, third: to

so. construct the engine,fltha t the gaseous fuel inducted therein shall not becom-pressed before ignition of the fuel, fourth; to pro-' vide anti-concussion means whereby abru t t e 'stopping of the outward movement of intake pistons is prevented.

Ifattain these objects by the mechanism illustrated. in the accompanying drawings,

in which "Figure 1 is a verticalsection of the engine,

secured on an engine base, (not shown,) by their respective stud bolts and nuts 3'v and 1".

Piston 5 is connected with crankshaft S, by'rod 9 and crank 10. Said crank shaft is extended through the crank case 11, and is rotatably mounted with said crank in said case. Said crank case is formed integrally with the adj acent ends of cylinders 1 andv 2.

Piston 5 andvpiston 6 are slidably mounted,

in said cylinders, respectively. Said pistons are rigidly connected by connectors 7 which are'formed integrally therewith.

Since said cylinders, their respectivepistons, and their hereinafter described respective coacting parts, form two sets of mechanisms, which are the same in construction set is described.-

plug 13, which is adaptedfto be connected .withan electric igniting system, and since said system may be anyone of the varlous f igniting systems now in use, and forms no 1 part of my lnvention, the same s neither shown nor described. J p 1 Said intake cylinder is provided with actuated tolclose' said fuel intake, by the spring 16. I

Intake cylinder 12 is also'provided with the exhaustoutlet 17, (see Fig. 2,) which outlet is provided with valve'18; A

Said valve prov ded with stem 18 which is'a'ctuated by spring 19 for. closing said "valve. (Jam 20 is secured on crank Intakepiston 21 is slidably mounted in intake cy1inder12, and is actuated to move outwarch bypiston springs 22.

Theouter end of SELlClPlStOIl is adapted to nclose and compress a certain amount of shaft .8,and is adapted by rotation thereof, past the inner end of said stem, to move the. latter and thereby open said valve.

Intake piston 21 is moved inward'by cam 23, which is rotated against friction roll 24;

said roll being rotatably mounted between the outer ends of piston rods 25, the inner ends of which are secured in piston 21.

Cam 23 is secured on the central portion of cam shaft 26, which latter is rotatably mounted in the outer ends of bearing brackets 27, which are secured on the outer end of intake cylinder 12. Sprocket wheel 28 is secured onone end of said cam shaft, and is connected by sprocket chain 29, with sprocketwheel 30, which is secured on crank shaft8. 1 In operation, with the parts in the position seen in Fig. 1, fly wheel 32 is manually rotated clockwise,- thereby rotating shaft 8 and the therewith connected cam 23. When the end of said cam passes friction roll 24,

piston springs 22 move piston 21 outward.

. preciable, distance.

V to that of piston 6.

This movement of said intake iston is radually stopped by a cushion of air, whichis formed in cushion chamber 12, "and escapes therefrom, through vent V cook 31. When said piston is thus moved, it produces a partial vacuum in cylinder. 12, which inducts a charge of explosive gaseous fuel intov said cylinder. .Said fuel is in; ducted from'an unshown source ofsupply,

tln'oughfuel intake 14, past valve 15, overcoming spring 16,, opening said valve, and .thence into cylinder 12 after which said V valve is closed by thelast mentioned s ring. It ,will'beunderstood, that the actlonof springs 22, moves said intake piston almost instantly, thereby filling cylinder 12 with said fuel, before piston 5 has moved an ap- At this juncture, said charge of fuelis ignited at spark plug 13, by the previously mentioned igniting system.

' Theflenergy" of the ignited charge drives piston 5, toward crank shaft 8, which, by its rod and crank connections, rotates saidshaft clockwise, until said plston hasreaohed the end of. its stroke,.and is in aposition, similar During the previously described operations, the last mentioned piston and its co acting intake piston, together .with their driving mechanisms, are moved-from the pof sition. shown, to a position similar to :the

2 shown position ofpiston 5 and its coacting Jparts. 1

Fly wheel 32 isnow rotatedby its own. inertia, which rotates shaft 8; and fits connccted' parts, thereby moving piston-6- and been moved, from their described positions, to the-positions shown. J

\Vhile piston 5 is thus being moved to'- ward its intake piston 21, cam 23 moves the last mentionedpiston inward, until said pistonsa're' in thejpositionshowmas previously .stated. V

During'the first half of this piston movement, exhaust cam 20 is rotated past the'end of valve stem 18, (seeFigsf2'an'd 3) ,there# by opening va1vel8. During thelast half of said 'movement said valve is closed by action of spring 19-.-:T. Atfthi s

juncture pistons

5 and 21,having reached the:1;;osition shown, have expelled, practically all of the productsof combustion, from cylinders l and12, through exhaust outlet and the thus openedvalve-18. I r

The inertia of fly wheel 32 continues rotating shaft 8, and theldescribed operations are repeated.v l
