'lhis invention relates to internal combustion engines, and more particularly torotary engines.

An object o f the invention is the provision of an engine having a piston carried by a rotating member secured to the main shaft and a casing in which the piston is adapted to rotate, together with means for closing a portion of the casing to form an explosion chamber, said means being automatically moved by suitable control mechanism upon each revolution of the piston to permit pas' sage of the piston.

.Al furtherobject of the invention is to provide a rotary engine yin which the number of parts are reduced tov a minimum.

A vfurther object of the/.invention is to provide improved means for feeding the rcharge to the cylinders. In the accompanying shown one embodiment In this showing: 1 v

Figure 7 is a horizontal sectional view on line 7-7 of Figure 1, and,

Fi ure 8 is a detail view the oiling mechanism. f

Referring to the drawings, the reference numeral 1 designates a main shaft which is'supported in suitable bearings and mounted in a, lower frame 2 The frame is substantially cylindrical and may be provided with a plurality of braces 3 adapted to support the shaft. As shown, suitable roller bearings 4 are arranged between the braces and collars 5 carried by the shaft. The top of the frame is shaped to form a motor `casing 6 which extends through an entire circle and which is preferably circular in vertical 5 cross section. Acarrier-l is mounted on suitable arms or spokes 8 secured to the shaft drawings, 1 have of the invention.

view on line 3-3 of 4 is a perspective view of one of of which portions to form an explo# of a portion of by through a chamber 10 into the motor cas.- ing. The inner face 11 of the carrier is curved to conform to the wall of the casing. Suitable roller bearings 12are arranged in the chamber 10 above and below the arms 8 and the carrier is provided with Suitable rings 13 to prevent leakage. As shown (see Figure 2), pistons 14 are supported by the carrier. Any number of these pistons may be employed but in this illustration,`I have shown two pistons arrangeddiametrically opposite each other. An abutment 15 is a-dapted to close off portions of the casing to `orm an lexplosion chamber. This abutment consists of a: substantially rectangular member adapted to slide in a valve casing 16 and provided with a semi-circular face 17 adapted to conformrto the walls of the motor casing. 'As shown,` he valve casing 16 is connectedto the motor casing through a passage 18. A ring or packing member 19 is arranged on the surface of the abutment and this ring is retained in operative position by means of springs 20, secured to the rear of the abutment. The sides of the abutment are provided with grooves 20 adapted to receive rods 21 formed on the walls of the chamber 16 to guide the abutment. The abutment is controlled by means of a pivoted lever 22 having a forked upper end providlng a pair of arms 23. A pin 24 extends'through slots 23 in these arms and throughthe abutment. The lever 22 is piv-v otally mounted on a bracket 24" and is provided with a slot 25 in its lower end adapted to receive an operating member 26. The other end of vided with a finger 27 adapted to engage cams 28 carried by a plate 29 secured tothe main shaft. Springs 30 are arranged on the operating members 26 and are adapted to normally retain the abutments in closed position. v

A pump 31 is arranged adjacent the engine and is connected to the main shaft by means of' a belt 32. This pump is adapted to deliver air to a compressed air tank 33. lThe tank may be provided with a suitable safety valve 34. A pipe 35 extends from the air tank to a mixing chamber 36. This. chamber is provided with a valve 37 normally retained in closed position by means of a spring 38 which surrounds the valve stemv 39. The end of the valve stem is adaptmeans of a key 9 and this carrier extends the operating member is proics to engage the periphery of the plete 29 to l i operate the' valve, and permit a charge of compressed air to be delivered to the mixing chamber. A fuel pipe 40 extends into the mixing chamber and is provided with a nozzle 4l on its end. The motor casing communicates with the mixing chamber through an inlet passage 42, normally closed by means of a valve 43. This valve is retained in closed position by a spring 44 and is adapted to be opened by suction.

Suitable exhaust valves 45 are arranged in the casing, these valves being normally closed by springs 46. The valve stems are connected to fingers 47, pivotally mounted in brackets 48 and the ends of the fingers are adapted to be received in grooves 49 formed on plates 50. These plates are carried by the arms 8 of the carrier and revolve therewith. Adjacent each of the abutments, there is provided a spark plug 51 which is adapted to ignite the charge in the usual manner.

Suitable means are provided for oiling the parts of the engine. A quantity of lubricating oil is adapted to be placed in the bottom of the'main casing 2 and a feed pipe 52 extends upwardly therefrom. This feed pipe is provided with a check valve 52 ad- ]acent its upper end and communicates with a pipe 53 which serves as a pump cylinder. A piston 54 is arranged in the cylinder and a spring 55 surrounds the piston rod. The outer end of the piston rod is provided with an enlargement 56 adapted to be engaged by a lug 57 carried by the rod 26. The pipe or cylinder 53 communicates with a pipe 58, the other end of which is arranged above the motor casing and is adapted to return excess oil to the bottom of the main casing. The pipe 58 communicates with an oiling device 59 having a reduced passage 60 and having a ball valve 6l arranged beneath the reduced passage. An oscillating valve 62 is arranged above the reduced passage 60 and is provided with an opening 63 adapted to be periodicallybrought into alinement with the passage. The valve is normally retained in closed position by means of a spring 64 surrounding the valve stem 65. The upper endof the valve stem is provided with a lateral extension 66 adapted to be engaged by an operating lever 67 which is slidably mounted in a bracket 68. A cam 69 carried by the main shaft is adapted l to reciprocate the lever to oscillate the valve.`

The motor` maybe provided with a cover 70 retained' 1n position .by suitable fastening elements 71.

In operation, the abutments l5 are normally in the position shown in Figure 2 of the drawings, closing the casing 6 and dividing it into two sections. As the carrier and pistons rotate, the finger 27 rides over the cam-surface 28 of theplate 29 pulling the @erwies-[leiter 26 inwardly .and thus casing, a carrier connected the valve is opened, permitting a charge to enter the casing abutment in the assumed the closed position. The spark plug 51 then furnishes a spark at the roper time to ignite the charge and force t e piston around in the cylinder. As the piston approaches the end of a stroke, the fingers 47 are swung on their pivots to open the exhaust valves and permit the burned gases to dischar e.

The reciprocation of the oil pump piston 54 draws a charge of oil upwardly through the pipe 52 and due to the check valve in the pipe 52, the next stroke forces the oil upwardly throughthe pipe 58. The oil is fed to the motor easing drop by dro by means of the valve 63 which is oscillizted by the cam lever 67 to dispose the valve opening 63 in alinement with the reduced passage 60.

It is to be understood that the form of my invention herewith shown and described preferred example of the between the piston and the 1s to be taken as a same, and that various 4changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
