(Cl. 12S-14) 1 This invention relates to rotary internal com bustion engines. An object of this invention is to provide a rotary engine having a substantially toroidal cylinder and a plurality of spring-pressed sliding abut ments carried by the casing. vAnother object of this invention is to provide 2 journalled in bosses I8 and I3 carried by the heads I2 and I3, respectively, the shaft I1 being sealed with respect to the bosses. or bearings I8 and I9 by packing glands 2U and 2I respectively. A bearing sleeve 22 is positioned within the boss I8 engaging about the shaft I1 and a second bear ing sleeve 23 is positioned within the boss I3 and engages about the shaft I1 inwardly from an engine of this type wherein air is compressed the gland 2I. and discharged into a tank on a portion of the A rotor generally designated as 24 is rotat stroke of the rotor so that the compressed air 10 ably mounted within the casing I0 and includes may be’returned to the firing chambers at the a central hub 25 which is carried or otherwise proper time mixed with the desired fuel. ñrmly secured to the shaft I1, as indicated at A further object of this invention is to pro 2B. The rotor 24 includes an outer cylindrical vide an engine of this type embodying an im member 21 which rotatably engages in annular proved valve construction which is actuated by 15 recesses 28 and 29 formed in'the’inner sides of the leading side of the rotor, and the leading the heads I2 and I3, respectively. The heads I2 side of the rotor is of cam shape so as to open and I3 are provided on the opposed edges thereof the intake valve in properly timed relation. with sealing rings 30 so as to seal the cylindrical A further object of this invention is to provide an improved rotor which may be formed with a 20 member 21 within the recesses 28 and 29. A pair of annular lubricating channels 3I and plurality of pistons so that a plurality of power 32 are formed in the heads I2 and I3 in a posi strokes will be provided for each revolution. In tion confronting the inner side of the cylindrical the form disclosed the rotor is formed with four rotorl member 21 for providing proper lubrication pistons and as there are two power positions for this member. The rotor 24 also includes a each piston, there will be eight power strokes for 25 for plurality of circumferentially spaced apart pis each revolution of the rotor. tons 33 which are secured to or formed integral With the foregoing objects and others which with the cylindrical member 21.

In apart pistons movable in said cylinder, a, hous ing extending radially from and secured to said cylinder, an abutment slidably carried by said housing and normally biased to a position across other words, housing 95 is slightly less than dia said cylinder, each piston including a cam metrically opposite housing 44 and the same is shaped leading portion engageable with said true of housings 43 and 96. abutment for moving the latter outwardly into Housings 43 and 44 being less than 45° apart, said housing, a fuel intake valve carried by said and rotor 24 having four pistons, rotor 24 will be housing, and means connected to said valve and under a continuous power impulse, the combus projecting into said cylinder in a position for en tion chamber 9| associated with housing 43 pro 10 gagement with said cam-shaped leading portion viding the ñrst or leading impulse. Combustion for moving said valve to open position, said lat chamber 9| associated with housing 43 will pro vide another power impulse before the gases have fully expanded under the ñrst impulse, so that in effect there will be two power impulses which are continuously acting to rotate rotor 24. What I claim is: A rotary interna1 combustion engine compris ing a substantially toroidal cylinder, a rotor in cluding a plurality of circumferentially spaced ter means including a bell crank pivotally carried by said housing and having an elongated slot in one arm thereof, a pin carried by said valve loose ly engaging in said slot, a second pin slidable through said cylinder, and means rockably con necting said second pin to the other arm of said bell crank.
