This invention relates to internalv combustion engines and more particularly to internal com bustion engines of the rotary type. 1 vAn object of the invention isto simplify the 5 structure of rotary internal combustion engines and at the same time to increase the power there of to. the end that maximum power'may be ob At the center thereof the plate I4 is provided The invention together with its objects and ad vantages will be best understood from a study of. the following description taken in connection withthe accompanying drawings wherein: ' manner of ‘mounting on the engine an injector -‘ work that is to be driven. Shaft I1 is journalled in a suitable bearing l8 bers 9a that connect the aforementioned frames 9 at the ends of the latter. Bearing l8 as shown is suitably provided at l9 for a lubricant ?tting and also with an oil ring 20. - Figure 3 is an enlarged detail sectional view through the injector cylinder and further illus ‘ Secured to the opposite end of the hub or cas trating the means for reciprocating the piston annular ing l0 through plate 22 in thewhich medium is ?tted of abolts babbitt 2| bear-. is an ’‘ forming part of the injector. ing 23. At its inner end the bearing 23 is pro vided with a ?ange 24 that has an edge portion 20 thereof clamped between the plate‘22 and the . j ’ . Figure 4 is a fragmentary plan view showing the means for reciprocating the injector piston. Figure 5 is an elevational view taken substan tially at right angles to Figure 3 and viewing the same ‘from the left of Figure 3. Figure 6 is a fragmentary plan view of the rim of the, rotor. > Figure 7 is an enlarged detail sectional‘view taken at right angles to Figure 1. , Figure 8 is a fragmentary elevational view from the’driving end or side of the rotor. Figure 9 is a fragmentary perspective view il lustrating certain details hereinafter more fully referred to. Referring to the drawings by reference numer als it will be seen that the internal combustion engine comprises an outer band divided into a pair of complemental sections 5, 6, which at their ends are provided with lugs ‘I through the medium 40 of which and bolts 8 the sections 5 and 6 are connected together and secured to the side mem 45 tends the main drive shaft I‘! that is adapted to be connected in any suitable manner with the provided therefor on one of the frame mem Figure 1 is a sectional view through the engine. Figure 2 isa detail elevational view showing the ‘ a cover plate l4 secured to the member l0 by ' bolts or the like l5. with a formation [6 from the center of which ex tained with minimum fuel consumption.‘ ' cylinder. the cylinders H are complementarily ribbed and grooved as indicated generally at I3. For vone side of the casing l0 there is provided bers 9 of any suitable stationary supporting frame structure. Revoluble within the con?nes of the outer rim is a rotor which includes a crank case in the form of a hub I!) from which radiates cylinders II. While any number of cylinders may be em ployed in the present instance there have been 0 illustrated but four such cylinders. At their outer ends the cylinders l l are integral with a rim or band l2 that has a rotative ?t within the outer band. As shown in Figure 7 the sections 5 and 6 of the outer band and the sections of the rim 12 between adjacent end of the hub or crank case in. The reference numeral 25 indicates one end of‘ an axle that extends through a bearing 25. and on the end of the axle 25 is a disk 21 which is accommodated within the bushing 23 as shown. Secured to this disk 21 as at 28 and disposed 5 against the outer face of the annular plate 22 is an oil retainer plate 29. Thus in this manner the rotor is supported to rotate about the axle 0 25 and its disk 21 has an axis. Disk 21 is provided with any desired number of concentrically arranged openings 30 into a selected one of which is placed'one end of an eccentric pin 3|. Suitably connected with the free end of the pin 3| is one end of connecting rods 32 pro vided for the piston 33 mounted to reciprocate within the cylinders ll. Obviously the desired compression is obtained by placing the pin 3| in the proper socket or opening 30 of disk 21. It will also be apparent that as the rotor revolves pistons 33 are ‘constrained to reciprocate within the cylinders I I and as the cylinders ?re in proper sequence the rotor will be caused to revolve as is 35 5 thought apparent. Provided in the ?xed outer ring section 5 is a port 34 into alinement with which and the in take port 35 provided in the rim l2 the cylinders H successively move for charging the cylinders H with fuel. For charging purposes there is provided an in jector which includes a cylinder 36 suitably mounted on the ring section 5 and adapted to be 0 55 2 2,109,185 connected at one end 31 with a carbureter (not intervals are contact elements 55 for use as a part shown). Inwardly from the end 31 cylinder 36 is pro vided with a guide bar 38 through which works a valve stem 39 provided for a valve 40 engageable with a seat 4| fixed within the casing 36 at the side of the guide 38 farthest remote from the end 31 of the cylinder. A spring 42 serves to yieldably retain the valve of the ignition system. 10 disk 40 engaged with its seat 4 I. Mounted for reciprocation within thecylinder 36 at the sidejof the seat 4| opposite to the‘ guide 38 is a piston 43 which serves to draw fuel into the cylinder 36 from the carbureter and, with 15 valve 40 open, pass the valve seat 4| to subse quently force the fuel under pressure through the 1 port 45, and through port 34 and the port 357 alined with the port 34 into the proper cylinder. For reciprocating the piston 43 as the rotor Also, the rim section 5 at a suitable point there- ' of will be provided with a spark plug hole 56 to accommodate the spark plug 51 for igniting the compressed charges in the successive cylinders. For the casing Ill there is also provided on the rim section 5 a suitable valve controlled vent as sembly 58. Also for cleaning out the cylinders there is 10 provided in thevrim section 6 an opening“ 59 with which the cylinders I I are caused to;isuccessively aline and extending from the opening 59 is a con .duit 68 through which air under pressure or the like may be ‘forced for use in cleaning out the 15 ' cylinders. ' Fonlubricating the contiguous faces of the outer ?xed ring and the rim l2 through the vmedium of the oil within the casing Hi there are 20 revolves there is provided on the free end of _. provided oil conduit pipes 6| that extend from 20 the casing ID to the rim I2 and these pipes are the piston rod 46 an arm 41 formed at one ‘end with-a hook 48. Secured to one side edge of the rim I2 of the rotor is a continuous cam ring which at intervals 25 has formed integrally therewith attaching brack-, ets 48 bolted or otherwise secured at 49 to the rim I2- The cam ring is corrugated to provide in alternation cam hollows 58 and cam humps 5|, and the hook 48 engages the‘cam ring in a 30 manner clearly-shown in Figures 3 and 7 so that as the rotor revolves the camring so engages the hook 48 that, through the medium of the cam humps 5| and the cam hollows 50, the piston 43 will be caused to reciprocate for drawing fuel into 35 the cylinder 36 past the valve 48 and subse quently forcing the fuel from the cylinder 36 ' into the successive cylinders II. The section 6 of the stationary ring is provided with a single exhaust port 5| and an exhaust manifold 52 is suitably secured to the ring sec tion 6 as shown in Figure" I. It will thus be seen ' that as each cylinder ll moves into alinement with port 5| the burnt gases‘will exhaust there from to be carried o? by the exhaust conduit 52. For each cylinder‘ ll there is also provided a . suitable, breather cap 53. ' Also in accordance with the present invention provided with suitable valves 62 as shown.
