Application med September 8,

, `'To'aill whom it may concern? Be it known that I, BYRQN Snom, a citizen of the United States, residingA at Pierce' City, in the county of Lawrence and i' State ofl Missouri, have invented certain new and useful Improvements'in Internal-Combustion Engines; and I do declare the olvlowing to be a full, clear, and exact descr1ption of the invention, such `as willenable "others skilled in the art to 'which it appel tains toinake` and use the same, reference being 'had 'to the accompanying drawings, and to the lettersand figures ofnreference marked thereon, which orm apart of this specification.

My inyention lrelates to internal combustion en giiies, and more particularly to an engine of this character wherein a plurality of pistons oscillate'tlirough sector j cylinders, ztfand wherein charges are taken into the cylinders at' either side of the, pistons coinf pressed, fired'v and exhausted upon. subsequent oscillations thereof, A 0 i t Itis the object of the present invention to 'a greatnumber of the parts employed in the operation'of the ordinary combustion engine are 'elimiated to provide a more substan-- $0' eiflciency' is accomplished due to the elimination'of such parts andra consequent reduction of friction. i

' mechanism and parts working in conjunction therewith. 4

The lower housing section 2 is here shown to contain two semi-spherical explosion chambers, each divided by a piston into right and left compartments, designated b nu- 'mcrals 4.4-4and 5 5', provided'wi pistons 6 and 7 that are rigidly mounted on and extending in the same plane/from` a rocker shaft 8 and are adapted to oscillate within their respective chambers through a predetermined arc which is somewhat less than the limits of the said chambers; the shaft 8 being extended the length of the Vengine housing and revolubly mounted in'bearings- 10- 11-12 inthe lower section and secured thereiniby the overlying ybearing portions 14.

The. rocker shaft 8 is extended somewhat beyond the housing at the rear of the engine and is thereprovided with alaterally extending crank arm 16 to which-is pivotally secured va connecting rod 17 which in turn connects with the crank arms 18 of a power `shaft 1,9.; thesaid` shaft 19 being revolubly parallel with. and beneath the housing section 2 andr carries a j ily 'wheelV 22,v

roper' intervals, I have provided each oftl e intake and exhaust openings with chamber 5; the intake exhaust closed. oscillation takes place one for two "complete The engine is also provided with the usual spark plugs 56 which are preferably arranged in a central position of each explosion chamber andv may be connected with a timer in any suitable manner.

'I'also provide the. pistons with packing rings 57 t'o prevent possibleA leakage between the ex v)losion chambers.

I alsopre er to inc lose the crank arms 18 and 16 with 'a housing 59 which' may carry 75 a lubricating fluid for automatically oiling the partscontaincd therein.

Presuming the parts to be so constructed,

IV will `follow the operation -of the parts through one-complete cycle, presuming that 30 Fig. I shows the parts at a starting point wherein the pistons 6-7 are at the limit ofV their travel ,in the direction shown: l The piston 6 has'just completed the com- Y pression stroke withirespect -to the compart- 35 ment 4, vboth the exhaust yand intake valves `communicating.therev:ith being closed, and the fuel being compressed therein.

the piston of the rear cylinder working in 'the 'saine -plane with the piston 6 is exhausting: a chargejfrom the chamber 5 'and combusti'on isi takingxplace; within the chamber 5.',.l-both1the exhaust and intake valvesof 100 compartment 5 andthinlet valve of compartment 5 being closedybutthe exhaust outlet from chamher-'beingopein I 'At the completion. 'of thecompression stroke o f cham r 4,' combustion takes' place 105 therein, moving the piston 6 vto its opposite. limit,l `compressing the 'chargei'in chamber 4'; both valves in chamber 4f being closed.

During 'this movement the'piston 7 within.

the,Z rear cylinderv is exhausting' 'a burned 1101i charge fromthe chamber 45 the exhaust valve being open and intake :vlve closed,

anda fresh `charge being taken into the valve being open?. and- On completion of the foregoinghiiiovelment, the 'compressed charge iii chamber-11'v `is fired, moving the piston '6 back to its' opposite'limit, and exhaustingithe burned. as from the chamber 4,`the exhaust vaive opened and-the intake valve closed.

*With this movement, the piston chiii- I dresses the charge in chamber 5, both valves` "i opening therei'iito beingl closed, and a fresh hargei being taken inf/0 chamber .5'.; the Y125 ntfkvalv being vpnd a'm1 theexhaust f .On-'completion `of .this movement, com- 'y .I

bustion'takes place in chamber 5,bth va1y es being closed, .the :piston A7 is moved to .the 13Q io poste -limifrrto compress the charge in cjarnber 5 -where both valves are cosed. During this operation the piston 6 is moved to exhaust the burned gas from .chamber 4'; exhaust valve being open'and intake valve With this arrangement of parts, it is apparent that the valves operate to uncover their respective ports -to impart a regular oscillating movement to the piston, which ,Willimpart .through the connections shown a rotatory movement to a power shaft.

l It is also noted that the number of operating parts of the ordinary engine is greatly reduced and a compact and` substantial engine provided which may be usedas a sta tionary engine,bu t Vis particularly adapted forl motor vehicles.

While the engine is shown to comprise but two cylinders I do not wish to limit it to this particular number, nor to the semispherlc'al shape shown, as in some cases it may be more practical to make the explosion chambers -of'g'reater depth. I

It will also be seen that by proper connections the engineinay be operated W'th steampower equally as Well as with t e combustible fuel.A

Having thus described my invention, what I claim as new therein, and desire to secure l. The coinbinatlon with a housing having semi-spherical portions containing independent semi-spherical piston chambers,

each of said portions having a protuberto said `rocket shaft'and operable in the separata chambers, a crank shaft journaled inthe protuberance bearings, and a rod connecting the rocker shaft and crank shaft.

2. The combination with a piston housing comprising'semi4spherica1 piston chambers arranged 11i longitudinal alinernent and having longitudinall alin'ing bearing seats therein, va, rocker siaft mounted in Said seats, pistons fixed tosaid shaft and ro jceted into said chambers, 'a cover Yate seated over said vpiston chambers and attached to said housing and having a longi tudinal channel vseat inclosing said rocker shaft; said housing and cover plate being water. jacketed, and intake and exhaust valves opening through the cover plate into said piston chambers at both sidesof said pistons.,

3. The combination with a piston housing comprising semi-spherical. piston chambers arranged in longitudinal alinement and having longitudinally alinirfg `bearing seats therein at the open side of the chambers and longitudinally alining protuberances extending from the. base of the housin forming journal bearings, `a rocker shaft mounted in said bearing,seats, acover plate mounted on said housing having longituinal-channel seats on its under face for receivin '.I and inclosin 'said rocker shaft and havI glstandards t ereon, a can shaft revolubly!l mounted in said standards in para -allel alinement with' the rocker shaft, pis-- tons fixed on the rocker shaft and pro'ecting into said chambers in longitudinal alinernent relative to the shaft, exhaust and intake valve me'chanisni operatively connected with the cam shaft mountedon saidcover and opening therethrough to. the piston chambers at'both `sides of said pistons, a. crank shaft -revolublfy 4carried in the housing protuberances, an actuating' rod connecting the rocker shaft with thel crank shaft and a belt operatively connecting the crank shaft with the cam shaft, for the purpose set forth.

In testimony whereof I aix my signature.
