Specification of Letters Patent.
Patented July 19, 1921.
Application led June 11, 1919. Serial N0. 303,325.
To all whom t may concern:
Be it known that I, STUART R. THORNTON, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Internal- Combustion Engines, of which the following is a specification.
This invention relates to internal combustion engines of the rotary type, and an object of the inventionis to provide, in a rotary engine, a rotor connected directly with the main power transmitting shaft which rotor carries a pluralit of circumfeentially spaced abutment mem ers concentric of the axis thereof, and resenting abrupt radial ends provided with cup-shaped recesses ada ted to form explosion chambers for the engine in which the fuel is exploded under compression,l for imparting energy to the rotor.
`A further ob'ect of the invention is to rovide a plurality of tangentially extending extensions u on the stator lof the rotary motor, in whic extensions are slidably mounted cylinders, in which cylinders are slidably mounted compressing and suction` creating pistons to scavenge the compression and explosion chambers of the engine during operation thereof and which cylinders co-act with cam surfaces formed upon the abutment members of the rotor to provide 'tight joints for the explosion chamber during the exploding of a charge of fuel therein.
Another object of the invention is to provide a novel construction for controlling the inlet of fuel into the respective explosion chambers, which comprises a plurality of fuel feeding tubes extending radially from and receiving their charge from the main power shaft of the engine and which open out into radiall extending cylinders having pistons slida ly mounted therein which are moved during the rotation Of the rotor by means of a cam cap to automaticall open and close the port entering into the cy inders, at the proper time to permit the combustible fuel to fiow thereinto which fuel is in turn. forced 'from the said cylinders into the explosion chamber of the engine by the outward movement of lthe said valve piston, where it is compressed by the inward movement of the pistons which extend tangentially from the stator.
Other objects of the invention will appear from the following detailed description taken in connection with the accompanying drawings forming a part of this specification and in which drawin Figure 1 is a side elevation o 'the improved rotary engine.
.Fig 2 is a vertical section through the engine.
Fig. 3 is a vertical cross-section through the engine. y
Fig. 4 is an enlarged detailed section through the cylinder portion of the engine illustrating the connection between the rotor and stator.
Fig. 5 is a detailed perspective illustrating the engagement between the rotor and the tangentially extending cylinders or sleeves, and
Fig. 6 is a section through the tangentially extending portions of the casing or stator of the englne, taken at right angles to the section therethrough illustrated in Fig. 2.`
Referring more particularly to the drawings, wherein like characters indicate like and correspondin parts throughout the several views, lindicates the supporting structure of the rotary internal combustion engine to which the stator 11 is rigidly connected as shown at 12. The stator 11 comprises a circular cylinder, which is also circular in cross section as shown 4in Fig. 4 of the drawings, and the rotor 13 rotates within the cylinder of the stator 11. The rotor 13 comprises an annular rin 14, the edges of which are shaped to form all races 15 which receive therein bearing balls 16. The circular cylinder of the stator 11 has its innermost rtion cnt away as shown at 17 in Fig.' 4 oixthe drawings, and the edges along this cut away portion are rolled inwardly to form ball races for co-action with the ball races 15. Suitable piston rings 18 are carried by the edges of the rotor 14 to provide fluid-tight connection between the rotor and the stator. This annular cut out portion 17 is formed to accommodate the spokes 19 which support the rotor 13, and which are connected to the power shaft 2O of the engine through the medium of a huh structure 21. l
The rotor. ring 14 has a plurality of enlargements 22 formed thereon, terminating in abrupt shoulders radial of the axis of the rotor, which shoulders are provided with substantially semi-spherical or cup shaped cut out portions 23 forming with a )ortion of the interior of the stator 11 the com ustion 26. The pistons 25 are adapted to permit the passage of combustible fuel from the tubes 27' into the hollow or` tubular spoke 24 1n advance of the pistons when the latter are retracted, and these valve pistons force the combustible fuel `which enters the tubular Y spokes 24 outwardly through relatively small outlet pipes 27 and 28 into the cupshaped recesses 23 for admitting a charge of fuel into the stator infront of each of the enlargements l22. The piston rods 26 each have an angled roller carrying arm 29 v'attached thereto which extends through a slot 30 in the respective tubular spokes and has a roller 31 upon its outer end. This roller 31 travels in an annular cam Way 32, carried by the stator structure and having depressions or depressed portions 33 therein, which when engaged by the roller 31 will retract the piston 25, permitting fuel to flow from the tubes or manifold pipes 27 into the tubular spokes 24. The tubular manifold or supply pipes 27 have communication through radial openings 34 with -the bore 35 formed axially within the shaft 20 for a portion of its length. The shaft 20,
has its outer end opposite to that which carries the pulley or other transmitting mechanism 36 connected to a fuel supply pipe 37 by means of a coupling connection 38 constructed to permit unlmpeded rotation of the shaft 20 without breaking the fluidtight connection between the shaft and coupling, and so as to permit fuel to pass through the pipe 37, coupling 38 into the bore 35 of the shaft 2O for feeding into the stator through the respective tubes 27 After the fuel enters the cup-shaped recesses 23 and the adjacent port-ion of the stator it is compressed by means of a plurality of pistons 40, one of which is disposed in facing relation to each of the abrupt shoulders-of the enlargement 22 upon the rotor. 1 The` pistons 40 are slidably mounted in sleeves 41, which are in turn slidabl supported by tangentially extending cy indrical extensions 42 formed upon the peripheryl of the stator 11. The sleeves 41 have arcuate recesses 44 in their outer ends for snugly fitting over the bulged portions 15 ofthe rings 14 of the rotor structor to provide comparatively fluid tight joints between the sleeves or cylinders 41 and the rotor. The .cylinders 41 have expanding springs 45 connected to their inner ends which springs are also connected to the ends ofthe tangential extensions 42, tending to normally urge the cylinders inwardly into the stator. The inner ends of the cylinders 41 are provided with inwardly extending flanges 46 which engage about the inner end of thepistons 40 when the latter are at their innermost positions, and springs' 47 are carried by the inner Walls of the cylinders and are adapted to engage'against the pistons 40 to connect the pistons and cylinders for synchronous movement. The piston rods 48 which are connected to the pistons 40 each have their outer ends connected, by means of a slot and pin connection as shown at 49 with a rocking arm 50. The rocking arm 50 is pivotally supported as shown at 51 by a suitable supporting arm 52v carried by the stator structure 11. The ends of the lever 50 remote from their connections with the piston rods 48 are connected to arms 53 which are in turn connected by means of bell cranks 54 to the shafts 55, carried by the stator structure. These shafts 55 are rotatably supported by the stator and have pinions 56 mounted thereon which mesh with a gear 57 carried by the power shaft 2O of the engine. The ratio between the pinions 56 and the gear 57 is such as to insure proper operation of the pistons during each cycle of operation of the motor. The compressed charge, in the stator or in the explosion chambers of the rotary engine is ignited, in the usual manner by means of spark plugs 58 and upon explosion, the expanding gases will impinge against the walls of the cup-shaped recesses 23 and force the rotor about its axis. This same expanding force of the exploding gases or fuel will act upon the inturned flange 46, tending to force the cylinders 41 rearwardly or outwardly into the extension v42. However, the cylin ers will not be permitted to move faster than the pistons 4() owing to the said flanges 46. The enlargements 22 have outer arcuate surfaces eccentric of the circumference of the stator and rotor which eccentric surfaces are shaped to maintain a substantially fluid-tight engagement withthe inner ends of the cylinders 41 during their outward or retracting movement, preventing the escape of the exploded gases fromthe combustion chamber of the engine. After the respective enlargements or abutments pass the cup-shaped enlargements 59 upon the stator, the spent gases or fuel enter these enlargements .and pass outwardly vthrough the exhaust pipes 60, exhausting into the extensions 42 and the pistons 4() upon their inward `movement create a suction in the extensions 42 and through the exhaust pipes 60 for scavenging the interior of the stator and drawing the exhausted gases into the extensions 42 from which they exhaust upon the retractng movement of the pistons 40 through outlet pipes 62` in which are positioned check valves 63. The check valves 63 prevent the sucking of air into the extensions 42 upon the inward stroke of the pistons 40 but permits the forcing of the exhausted gases out of the cylinders upon the retracting stroke of the pistons. Check valves 64 are positioned in each of the exhaust pipes 6() to prevent the spent gases from being forced back into the stator.
