The invention relates to rotary engines of the type comprising a casing having rotating discs provided with cooperating pistons movable towards and away from each other for the cycles of operation, and which discs are driven from an internal gear ring through cranks and link connections for the various piston operations for imparting rotary movement to a shaft rotatable with one of the discs.
A further object is to place the discs in facial engagement and to provide a driven crank shaft extending through one of the discs and rotatable therein and through arcuate openings in the other discs and terminating in cranks to the outside of the last named disc and. having link connections to the outer side of the last named disc.
A further object is to provide adjusting means in connection with the links whereby the relative movement of the cooperating pistons in relation to each other may be varied for allowing the engine to be operated with different kinds of fuel for varying the compression, thereby a1- lowing the utilization of low grade fuel and the operation of the device on the Diesel principle.
A. further object is to provide breather means to the rear of some of the pistons carried by the discs and discharging through the driven shaft, which breather means also acts as cooler means by the exhaustion of hot air and the intaking of cool air during the piston operations when going through their cyclesof operation.
A further object is to provide breather pipe connections between the driven shaft port and the rear sides of some of the pistons, and through an annular manifold pipe.
A further object is to provide means whereby the pistons may be easily attached to or removed from the discs.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is an improvement on my prior patent application Serial Number 72204, filed April 1, 1935, Patent No. 2,092,254, September 7,
Referring to the drawings, the numeral 2 des- 16 ignates the casing of the rotary engine and 2 and 3 sections thereof having annular groove and rib connections 4 of a packed type for forming a leak proof connection between the sections. The sections of the casing are connected together by means of transverse bolts 5 as shown in Figure 1. Sections 2 and 3 form an annular piston chamber 6, round in transverse cross section, and in which the movable parts of the rotary engine are disposed. Extending axially through the casing is a drive shaft 1, the ends of which are supported on antifrictional bearings 8 of the cover plates 9 and Hi. Secured to the shaft i by means of bolts lila, extending through a flange i i of the shaft 1, is a power disc i2, which disc has secured thereto on its outer side and countersunk in said outer side the arms i3 of power pistons l4. Arms 13 terminate in transverse arms 15 secured to the pistons, therefore it will be seen that it will not be necessary to form the power pistons 35 54 as an integral part of the power disc l2. Power disc i2 is provided with a rib and groove packed connection IE to the casing section 3, as clearly shown in Figure 2.
Rotatably mounted on the shaft 1 on antifrictional bearings IT, and in facial engagement with the power disc I2 is a head disc I8, which head disc has a groove and rib packing connection with the disc I2 and with the casing section 2 at IBa and 20, therefore it will be seen that 45 leakage between the casing and between the discs is prevented during the rotation of the parts.
During the operation of the engine the head pistons l9, carried by the head disc 18, are intermittently and simultaneously advanced and retarded for completing cycles of operation in the usual manner for the intake, compression, power, and exhaust operations, and these zones of operation are indicated in Figure 1 wherein the pistons are in open position, and at the ends of the 55 particular operation. During the operation of the device, the pistons l4 and [9 moved relative to each other, that is to open and closed positions for driving under the impulse of the explosions the power pistons M in the direction of the arrow a, Figure 1, for imparting a continuous rotation in said direction to the engine drive shaft 1. It will be noted by placing the discs l2 and IS in facial contact a positive structure is provided, taking up the minimum amount of room and obviating the formation of a chamber between the discs, which is now the practice. By placing the discs in facial contact and operating the discs through link connections to the outside of the disc I8, all the working parts can be easily reached for repair and inspection purposes without dismantling the entire machine;
The discs are operated by means of an internal gear raceway 2| carried by the casing section 3, and with which internal gear the planetary gears 22 carried by the power disc l2 mesh, as clearly shown in Figures 2 and 3.
The adjusting blocks 3| are held in adjusted position by means of yokes 36, which are detachably connected by means of screws 31 to the outer face of the head disc l8, therefore it will be seen that when it is desired to change the stroke, it will only be necessary to remove the cover plate ill by removing the bolts 38 and ready access may be had to the stroke adjusting means as well as the other working parts, therefore it will not be necessary to dismantle the machine casing as a whole. When it is desired? to change the stroke the: yokes 36 are removed along with the screws 31=and then the blocks 3| are rotated one hundred and eighty degrees after the links 30 are disconnected: or with them in place if desired. This operation places the extension arms 33 of the blocks on the opposite side of the axis of the shafts 34, consequently the links 30 move the pistons closer together thereby varying the stroke. After the adjustment of the blocks the yokes 3B are again placed in position for holding the blocks in this suggested position. The same istrue when access is desired to the opposite side of the engine and at which time the cover plate 9 is'removed.
As-the power and head discsrevolve the cycles of operation take place. Referring to Figure 1, it will be seen that opposite pistons I4 and I9 are on the power stroke while the other pairs of pistons are at the ends of the intake stroke, and upon the further advance of the head disc IS, the charge is compressed between each pair of pistons 14 and IQ for the firing operation at the spark plugs 39. The intake ports 40 are oppositely disposed and the charge may be controlled in any suitable manner. It will be noted that the intake ports 40 and exhaust ports 4| are in the casing section 3, and as the upper pair of pistons to the left are at the end of the power stroke, the adjacent piston IQ of the head disc will be advanced by the link connection during the movement of the power piston I4, and will rapidly catch up with said piston for the exhaust operation through the'port M. The same operation takes place at the opposite sides of the engine, and the operation continues during the running of the engine. through any suitable valve means.
From the above it will be seen that a compact rotary engine is provided of the disc type wherein the discs are in facial engagement and the head disc is advanced and retarded through a driving connection of the planetary gear type, extending through the power disc and an elongated bearing boss 25 and a crank and link connection to the outside of the head disc, thereby'simplifying the machine and reducing the number of parts.
During the operation of the device it is desirable to provide breather means for the chambers between the cylinders formed by cooperating pistons l4 and !9, so air will not become compressed therein or a vacuum formed therein.
To accomplish the breather operation the power disc !2 is provided with a plurality of ports 42, Figures 5 and 4, which ports discharge through the rim of the power disc and have connected to their inner ends outwardly extending pipes 43, which discharge into the anular discharge pipe 44. Annular discharge pipe 44, at spaced points, is provided with inwardly extending pipes 45, the inner ends of which are connected in radial ports 46' in the drive shaft 7. Ports 46 are in communication with an axially disposed discharge port 41 in the drive shaft, therefore it will be seen that air may be sucked from the atmosphere or discharged from the atmosphere during the operation of the engine, and that this breather operation will not only prevent a vacuum forming or compression operation between the pairs of pistons l4 and I9, but will also suck in cool air for cooling the cylinders, which is partciularly desirable in high speed engines, and in short stroke operations. If desired, to add additional cooling means it will only be necessary to force cooling air to the breather system, and this system can be also used for forcing lubricant into the machine.

l. The combination with a rotary engine comprising a casing, discs mounted in said casing, cooperating pistons carried by said discs, means for moving said pistons towards and away from each other for the cycles of operation thereof, a shaft carried by said disc and driven thereby, of breather conduit means extending through the shaft and in communication with the chambers between the pairs of pistons and through the rim of one of said discs.
