This invention relates to rotary motors of the internal combustion type. I

An Object of the invention is the provision of a rotary motor in which the expansive force of the combustible fluid is directed against an abutment of a moving element having a plurality of diametrically disposed grooves adapted to be alternately placed in communication with a compression and firing chamber. V Another object of the. invention is theprovision of a rotary motor having a cylinder enclosed by a casing and provided with a plurality of diametrically disposed grooves in which the end walls of the grooves are inclined so that said walls will engage and progressively move outwardly pairs of spring-pressed sliding abutments having their free ends normally seated within the grooves, a firing chamber formed in an enlargement of th casing and spanning the grooves so that an end wall of one groove will operate to compress the fluid in the chamber where it is fired and passed through i a diametrically disposed groove where the expanding combustion gases .will act on an end wall of the last-mentioned groove and cause rotation of the cylinder.

1 A further object of the invention is the provision of a rotary. motor having a cylinder revolvably mounted within a casing in which is incorporated a combustion and compression chamber, said cylinder having dia metrically disposed grooves, the walls of i which co-operate with sliding abutments and the outer wall of the combustion chamber to define said combustion chamber, the casing having an inlet port for the admission of a combustible fluid to one of the grooves and an exhaust port adapted to be placed incommunication by the other groove.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming a part of the specification; nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended the line 4- .2 of Figure 2,

Referring more particularly to the drawings, 1O designates a housing formed of a pair of sections 11 and 12. The section 11 has a water jacket 13 embracing a firing chamber 14 while the section 12 has a water jacket 15 embracing a diametrically Opposite 80 portion of thecasinga The section 11 has flanges 16 bolted to a flange 17 of the section 12 and both flanges are secured to supporting beams '18 forming part of the frame a I Mounted within the casing 10 is a cylinder or motor 20 which is firmly secured to a shaft 21. This shaft has its ends mounted in bearings 22 and 23.

A pair of circumferential grooves 25" and 9 26 are formed in the'outer face of the cylinder and are designated, respectively, as the com pression and firing grooves. A segmental ring 27 is mounted within the groove 25 and thereby closes approximately one-half of the annular groove, leaving a space 28 which is adapted to receive the combustible fluid from the intake 29. The groove 26 is filled for approximately one-half its length by'means of asectional ring30,'leaving a space 31 which is termed the firing or exhausting channel of the rotor.

The ends of the sectional member 27, as shown at 32 and 33, are inclined to provide tapering walls for the semi-circular channel 28. The ends 34 and 35 of the sectional member 30 are likewise tapered and form inclined walls for the ends of the channel 31 for a purpose which will be presently explained.

t will be noted that the sectional members 27 and 30 are secured by means of bolts 36 to the rotor 20. As a matter of fact instead of forming the annular grooves 25 and 26 in the rotor 20 and then filling a portion of the groove with the sectional members 27 and 30, respectively, the channels 28 and 31 may be cut into the outer face of the rotor at diametrically opposite points and approximately the same results will be had.

A pair of housings 4O and-41 are mounted on the casing 10 and upon opposite sides of the chamber 14 and in such a manner that the inner ends of the casing 40 will be in communication with the groove 26 while the inner end of the housing41 will be in open communication with the groove 25. .The

outer end of each housing is closed by a cover 42 removably attached to the housing in any approved manner.

A pair of abutments 43 and 43 are slidably mounted within the housing 40 and have stems, respectively, 44 and 44, movable through the cover 42. Coil springs 45 embrace the stem and are adapted to be embraced between the outer ends of their respective abutments and the inner face of the cover 42.. The inner ends of the abutments are circumferentially alined and adapted to normally ride within the channel 31 until engaged by the sectional member 30. The inclined face 35 of the member 30 is adapted to slip under the curved portion 46 of the inner end of the abutment 43 and also beneath the curved portion 47 of the abutment 43 and gradually force the abutment outwardly against the tension of the springs 45 during the revolution of the rotor 20. The housing 40 is located adjacent the-exhaust passage 48 which is adapted to communicate with the channel 31. 1

Referring more particularly to Figure 5 it will be seen thatthe housing 41 contains a pair of sliding abutments 50 and 51. The inner end of the abutment 50 is curved at 52 so that, the inclined face 32 of the member 27 may slide readily beneath the abutment and force the same outwardly- This is true of the abutment .51 which also has a curved portion 53 to facilitate the insertion of the inclined face 32 of the member 27. The abutments 50 and 51 are respectively provided with stems 54 and 55 embraced by springs 56 which .tend to maintain the abutments in engagement with the rotor 20.

At one side of the combustion chamber 14 is placed a sealing plate 60 mounted with a housing 61 which is in communication with the groove 25. A spring 62 embracing the stem 63 secured to the plate 60 maintains said plate in engagement with the outer surface of the rotor 20. Said plate is adapted to span the space between a pair of sealing rings 64 and 65 which aremounted within grooves in the rotor 20. These rings are secured by means of bolts or screws 66 to the annular wall of the housing 10. A sealing plate 67 is adapted to normally engage the outer face of the rotor 20 and is maintained in engagement with said rotor by meansof a spring 68 embracing a stem 69 secured to the plate 67. Said plate is located within a housing 70, and is provided with a lubricating passage 71 so that lubricant supplied through a passage 72 to the housing will be evenly distributed over that portion of the rotor 20 which is engaged by the plate 67 The plate 60 has a passage 73 for supplying lubricant from the housing 61 to the outer face ofthe rotor 20. Lubricant is supplied through the housing 61 by means of a pipe 74 which may be connected with a source of lubricant under pressure. The plate 60 spans the groove 60, the ring 64 and a ring 75 secured to the housing 10 and adapted to seat within a groove 76 formed in the rotor 20.

The sliding abutments 43 and 43 are re spectively provided with longitudinal passages 76 and 77 which are supplied with lubricant in any approved manner under pressure. The sliding abutments 50 and 51 are respec tively provided with longitudinal passages 78 and 79 through which lubricant is supplied to the face of the rotor 20. A conduit 80 is connected with the housing 41 for supplying lubricant under pressure to the conduits 78 and 79.

The stem 44 is provided with a pin 82 re ceived within a slot 83 of a lever 84 pivoted at 85 on a stem 86 carried by the housing 40. At the outer end of the lever 84 is secured a cam member 87 engageable with one end of a sliding bar 88 mounted in guides 89. This bar is spring-pressed to maintain it in normal engagement with the cam member 87. This bar operates a switch 90 which makes and breaks the circuit to a spark plug 91. The contact breaker represents but a portion of the ignition system but it will be appreciated that the usual elements of any wellknown igni-' tion system may be employed andmay include the high and low potential coils and a condenser." Y I In a modified form of the structure'shown in Fig.8, a sealing strip 94 is mounted within a recess 95 formed between the housing, 40 and the outer wall 96 of the compression chamber 14 and a plate 97 which is secured to the housing 40 and the wall 96. A spring 98 tends to maintain the strip 94 in engagement with the rotor 20.

It will be appreciated that the annular grooves 25 and 26 may be rectangular in cross section as shown in Figures 1 to 6, inclusive, or they may be semi-circular or angularlyshaped as shown at 100 and 101. In this case the sectional member 102 has its side Walls shaped to conform to the inclination of the side walls of the groove 100 and 101.

The operation of my device is as follows: Either a heavy fuel in connection with compressed air or a combustible mixture may be employed for supplying the motive fluid to the engine. WVhen a combustible mixture is employed the carbureter is placed in communication wit-l1 the intake 29 and if necessary a pump may be employed for withdrawing the mixture from the carbureter and forcing it into the intake.

Whatever method is employed for supplying the combustible fluid to the engine it is directed through the intake 29 into the channel 28 and as the rotor 20 is revolved the inclined face of the wedge-shaped portion 32 of the member 27 moves beneath the sliding abutments 50 and 51 forcing them outwardly while beginning the closure of the intake port 29. The combustible fluid being located between the wedge-shaped member 32 and 33 is carried around until the face 33 enters the combustion or compression chamber 14. At this time the full length of the channel 28 passes through the combustion chamber until the face 33 enters said chamber. At this time the combustible mixture is compressed in the small space of the chamber. The sliding abutments 50 and 51 are then in the position shown in Figure 5. About the time that the face 34 of the member 30 is passing through the combustion chamber 14 the compressed fluid is ignited and acts on the face 34 of the member 30 during the expansion of the gases. At the same time the face 32 of the piston 27 has passed through the chamber 14 so that the expanding gases will have no effect upon the compression piston.

The face 35 of the member 30 enters the combustion chamber and sweeps it clear of exhaust gases and said exhaust gases are then confined in the channel 31 of the rotor 20 and will exhaust when the rotor reaches the position shown in Figure 6. By this construction the channel 28 acts as the intake while the face 32 of the member 27 compresses the combustible mixture. The channel 31 receives the exhaust gases while the expanding gases act on the face 34 of the member 30. It will be noted that the member 27 is effective for the intake stroke and for the compression stroke while the member 30 is effective for the expansion stroke and exhaust.

Instead of the grooves 25 and 26 being formed in the rotor 20 and then filling a portion .of the grooves with a section of the members 27 and 30, respectively, the said members may be secured at diametrically opposite points on the rotor so that they will ride in grooves cutin the overlying casting or housing 12 whereby approximately the same results will be obtained.

A rotary engine comprising a rotor, a casing housing the rotor and provided with a compression chamber, said rotor having a pair of spaced annular grooves, a semi-circular sealing strip secured in each groove and provided with tapered ends, one strip being located directly opposite the other strip, one of the grooves forming an intake and compression channel, the other groove forming an expansion and exhaust channel, the compression chamber extending across the rotor with the chamber tapering from the firing and compression channel to and across the expansion channel, a pair of co-operating spring-pressed abutments for each channel having the free ends thereof normally disposed in their respective channels and slidably mounted in an offset of the casing, the
