i Corresponding :ind like parts are referred 'to in the following description, and indicated in all the views of the drawings. by the saine reference characters.

rIlhe. engine comprises a sha-ift 1, which is mounted in suitable hearings carried hij a hase or stand 3. A dish or like part i secured to the shaft] 1 to rotate therewith and is provided with laterally extending rings 5 'and 6 having concentric arrangienient and spaced apart, each of the rings having curved openings or passages forniing` buckets, varies, or abutnients tor the motive medium to iinpaet iinst to expend its force for driving2 the rings and the pert- A. stationary disk 'or plete is mounted in line with the disk and provided with rings or flanges 9 and 10 in which openings are formed. The outer linnn/'e or ring` 1G closes the space formedv between the two disks or vplates l and S so :is to conine the exhaust motive medium which enters en annular passage 11 and passes olf through a port 1Q to a convenient point of discharge. The ring or flange 9 has openings 13 which give proper direction to the or motive medium without leaving the ahutnients of 'the ring 5 so as to direct seid gases upon Athe shutting portions or the ring 6 to iinpart movementthereto. The rings of the f 'I d i8 lt te rl" dwo parts anc ai erna4 e. ne openings in the stationary ring; provide gates for .directing the motive medium or gaseous products resulting from combustion upon the buckets or abutting portions of the ro tary elements. A huh'or casing 14 occupies a central-position and is made hollow to form a combustion 'chain er 15. -'lfhe inner endet the casing or huh 14 extendsinto the space formed between the disks or plates rsnd 8 and has e. plurality of openings 1G 'tlmilgh which the products oi combustion pass to the abutting portions of the ring or space inc'losed by the casing or hub 14 'und hasports formed therein, which are adapted to register with passages' 18 formed in a' wheel 19 secured to the shaft 1 so as -to rotate therewith. It is to he understood that the partition 1? znay he'arrenged to rotate with 'the shaft 1 in which case theparty 19' will be stationery.

ing le and communicates withtliecornhus partition 17 snhdivides thev 20, which is formed to' provide a-'valve seat.4

The chamber ,214 is smaller than the chamber 22 and 'ai pipe 26 connects therewith-for supplying air'thereto under pressure, said pipehavi-ng connection With a reservoir 27a. I

Liquid fuel issprayed into the chamber 22 through-a nozzle 27 to'which a'pipe 28 is connected, said pipe leading'from a tank or other source for sup lying liquid fuel, such as gasol'ene, under piiess'ure. The two valves 24 and "25 are attached to a stem 29, which is arrangedV to operate in the casing 20, a spring '30 .serving normally to hold :the valves seated. 'The stem 29 is attached to one end o f a lever 31, the opposite end of said lever having a rod 32 attached thereto andarranged to operate through a guide 33. A lever 34 has one end arranged in the 'path of a tappet wheel 35 mounted upon the shaft l, the opposite end of said lever being l attached to a rod 36, which is connectedto one end'of a rod 37. The two rods 36 and 32 are normally in alinement so that operation of the lever 34 by means of the tappet Wheel 35 lifts therod 32 and moves the lever 31 to effect anunseating of the valves 24 and 25, whereby a gaseous mixture passes into i the combustion chamber 15.

The rod 37 has connection with a governor mechanism 38, which is so arranged that in the event of the engine'exceeding a. given speed the rod 36 is moved to throw its upper end out of line with the rod 32, thereby preventing movement of the rod 32. when the rod 36 is lifted, with the result that the valves 24 and remain closed and .no mixture is supplied to the combustion chamber.- This re- `sults in reducing the speed of the engine when the rod 36 is moved into operative position so that upon the next upward movementthereof the rod 32 is operated and the valves 24 and' 25 unseated, thereby permitting a charge of gaseous mixture4 passing into the combustion ,chamber to be ignited for operating the engine Il`hegaseous mixture may be exploded by any suitable igniter and it is preferred to have the parts so arranged as to produce a number of explosions during one revolu` tion of the engine. The preferred form of igniter utilizes an electric current which is established the required number of times during each revolution of the engine and at the proper time so as to produce an explosion an instant before the ports in the parts 17 and 19 are caused to register., The igniter comprises an electrode 39, which. is stationary and a rotary electrode 40, which is rotatable with thewshaft 1. The contacting points of the electrodes 39 and 40 are so positioned as to produce the spark at the proper instant, the number of explosions during each revolution .ofi the engine depending upon the number of' contact points embodied ,in the rotaryelectrode 40.

In the operation of the engine an air compressor 41visl arranged to be driven from the shaft l and supplies `the reservoir 27aL with compressed air. When the engine is in linedfor a shortv interval of time, during which the Avalves 24 and 25 close, after which the mixture is exploded andan 'instanti thereafter the products `of combustion are released and pass through the openings -18 and 16 and exerts its force upon the Wings, varies, or abutting portions of the rotary element 5 and after expending its force upon lsuch rotary element the mixture passes through the openings 13 and again exerts' a force upon the abutting portions of the ring or flange 6, after which it passes through the openings of the flange or ring 10 into the assage 11 to a point of discharge. ySo ong as the engine is running normal the rod 36 engages the rod 32 and 4 unseats the valves 24 and 25 at each operation of the lever 34, but should the speed of the4 engine become excessive the governor mechanism 3S moves thefrod 36 out of the path of the rod 32, thereby preventing the engine receiving a charge with `the consequent result that the speeddiminishes.

From the foregoing description, taken in connection With the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to whichthe invention 'appertains, and While I have described the principle of operation of the invention, together With the device which I now consider to be the embodiment thereof, I desire to have it understood 4 that the device shown is merely illustrative', and that such changes may be made when desired as are wit-hin the scope of the claims appended hereto.
