Specification of Letters Patent.
Patented. May 2%, 19216 application filed October 7, 1918. Serial No. 257,155.
To all whom it may concern:
Be it lmown that 1, Omar E. PETERSON, a citizen of the United States, residing at Idaho Falls, in the county of Bonneville and State of Idaho, have invented a new and useful Rotary Engine, of which the followin is a specification.
This invention relates to internal combustion engines, and more particularly to an engine of the rotary piston type, wherein the operating fluid which may be either steam or gas, is fed into an inlet chamber, under pressure, and from this inlet chamber, into the circular cylinder of the engine for impinging against a piston which moves in a rotary path with the cylinder; and an object of the invention is to provide an internal combustion engine which eliminates crank motion, giving the maximum efficiencyupon the utilization of a minimum amount of fuel, and an engine which eliminates the undesirable motions, caused by the starting and stopping of the engine.
Another object of this invention is to provide, in a rotary engine as specified, a pivotally mounted abutment carrying suit-able cushioning springs, which is normally projected across the circular cylinder of the engine, and is forced by the compression of air between it and the movable piston, out of the path of the piston allowing the latter to pass the said abutment after which the abutment will fall, under gravity, to its normal position across the cylinder and confine the inrushing operating fluid to the space between the piston and this abutment.
Other objectsof the invention will appear in the following detailed description, taken in connection with the accompanying drawings, forming a part of this specification, and in which drawings:
Figure 1 is a vertical section through the improved rotary engine.
Fig. 2 is a vertical section through the.
3 with the inlet chamber 4 of the engine, whlch in case volatile'gasis utilized as a fuel comprises the explosion chamber, the gas being exploded therein by a spark created through a spark plug 5 of the ordinary construction. A; valve cone 6 is provided for controlling the passing of the fuel from the initial inlet chamber 1 into the chamber 1 and this valve is carried by a valve stem 7. The valve stem 7 projects downwardly through the lower wall of the chamber 1, passing through a stuiiing box 8 to form a fluid tight joint about the valve stem and it has its lower end forked as indicated at 9, carrying the bolt or pin 10. A cam roller 11 is rotatably carried by the forked end 9 of the valve stem 7 and rides upon the periphery of a cam 12 carried by the main shaft 13 of the engine structure. The cam roller 11 is held in engagement with the periphery of the cam 12 by a spiral spring 14: which is coiled about the upper end of the valve stem and has its lower end engaging against a collar 15 carried by the valve stem while its upper end engages against the inner surface of the top of the housing 16 for the spring. A stufiing box 17 is provided for forming a fluid-tight joint or closure about the valve stem as it Ipasses upwardly to the wall of the cham- The fuel passes from the chamber 4 through an opening 18 into the circular cylinder 19 of the engine which cylinder surrounds the shaft 13 and is formed within the stator 20 of the engine. A rotor 21 is keyed to the shaft 13 and it has a ring 22' formed thereon to which a connecting rod 22 is attached which has its outer end con- 'nected to the connecting pin 23 of the piston ported by suitable pins 26 which are car-.
ried by the stator 20 and it has its lower inner end cut away as shown at 27 to fit the inner wall of the cylinder 19. The
in Fig". 2 or" the drawings, a twin cylinder or two cylinder engine is shown, and the construction of these cylinders is identical, the only dillerence being in the positioning of the cam 12 to permit operatlon of the valve 6 at different times so as to provide a continuous power strolre upon the shaft 13,
if so desired, a portion of the stator which forms the inner wall of the cylinder may be made separately from the stator proper comprising a circular ring or member indicated at d0 which is removably seated be tween the separate portions all and i2 of the stator and attached thereto in any suitable manner such as by bolts 43, thus enablin these sections of the stator to be remover for replacing them with new sections in case they become worn.
Changes in detail may be made without departing from the spirit ot this invention, but;
