means for first causing one set to act as,

abutments for the expanding gases of the exploded charges of fuel, so that these gases will act on the pistons of the other set to give them their propulsion stroke and then to cause the pistons of the second set to act as abutments, so that the gases of the new charges will act against the pistons of the first set. Thus the pistons will be given a step b step movement around the clrcular path tormed by the cylinder, first one set moving under the action of the expanding gases and then the second set.

Another object of the invention is to provide novel means for transmitting the movements of the pistons to a shaft which passes through the center of the device.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and s ecifically pointed out in the appended c aims.

In describing my invention in detail, reference will be had to the accompany ng drawings wherein like characters denote like or correspondin parts throughout the several views, and 1n which Fi ure 1 is a side view looking toward one s1de of the device.

Figure 9 is a face view of one of the plIllOIlS.

Figure 10 is an edge view of the inion. In these views, 1 indicates a casing which is formed of two parts bolted together and WlllCh forms an annular cylinder 2, provided with the water jacket 3, and the chamber 4 which is surrounded by the cylinder or chamber 2, the two chambers being in communicatlon with each other by the annular opening 5 which is formed in the dividing wall between the two chambers. A shaft 6 passes through the center of the casing, which is provided with the central bosses 7 provided with the passages for the shaft and having the ball bearings 8 and the packing glands 9 for said shaft. The bosses are provided with the base parts 10 which are designed to engage suitable supports for holding the device in upright position. A plate 11 is arranged within the chamber 4 and is fastened to the shaft by its boss 12 and a second plate 13 is bolted to the plate 11. The plate 13 is of ring shape and surrounds a gear 14 which is bolted to an interior boss 15 on one of the sections of the casing. Plate 13 is also provided with four recesses 16 for receiving pinions 17 which engage the gear 14 and which are rotatably supported by the plates 11 and 13 by having their hubs 18 engaging aligning openings in the plates, ball bearings 19 being arranged in the openings to provide antifriction means for the hubs of the pinions. Each hub. of each pinion is provided with a crank pin 20 on which is placed a roller 21, roller bearings 22 being provided for each roller. A pair of saucer shaped plates 23 and 24 are arranged in chamber 4 and have their flanges 25 abutting and extending into the slot 5. These plates extend over the lates 11 and 13 and the pinions" carried t ereby and each saucershaped plate is provided with a large central opening 26 and four slots 27 which have their inner ends in communication with the opening. The .slots 27 receive the rollers 21 on the crank pins of the pinions, and attention is called to the fact that the crank pins of each pinion are arranged diametrically opposite each other on opposite faces of the pinion so that one pin extends into a slot 27 of the plate 23, and the other pin will extend into a slot 27 of the plate 24, as

shown in Figure 4. Each of the plates 23 and 24 is provided with the ears 28 which extend into the cylinder or chamber 2, and the arc-shaped pistons are attached to these cars b the pins 29. Four pistons 30, 31, 32 an 33 are connected with the plate 23, and four pistons 30','31, 32 and 33 are connected with the plate24. A spark lug 34 is in communication with the top 0 the cylinder and a plug 35 is in communication with the lower part of the cylinder. Elongated exhaust ports 36 and 36' are arranged at diametricall opposite points in the cylinder and simi ar- shaped inlet ports 37 and 37 are arranged at diametrically opposite points in the cylinder. The inlet ports are connected together by the inlet manifold 38 and a suitable manifold may be connected with the exhaust ports.

From an inspection of Figure 3, it will be seen that when the charges at the top and bottom of the cylinder are fired by the spark plugs, the cylinders 30 and 32 of plate 23 will be given their propulsion stroke by the expanding gases, and 1n this movement the plate 23, hearing against the rollers of the crank pins of the upper and lower pinions, will cause the pinions to travel around the gear 14, and as the inner crank pin of each of the upper and lower pinions moves in an arc in t e slot of the plate 24, this plate and its pistons are prevented from having rearward movement from the pressure of the gases, but is given a slight forward movement, so that t e pistons of plate 24 will take the positions formerly occupied by the pistons of plate 23, while said pistons of the plate 23- W11]. move to a position formerly occupied by the pistons of plate 24. In other words, the piston 30 of plate 23 will move to the position formerly occupied by the piston 31 of plate 24, while piston.

. 31 of plate 24 is moving to the position formerly occupied by piston 30 of plate 23. On the next action, the plate 24 and its pistons will move to a greater extent than the plate 23 and its pistons. Thus the plates and the pistons are given a step by step rotary movement, first one set of pistons moving to a'gneater extent under the propulsion action of the expanding gases, while the istons of the other set act as abutments and move to a lesser extent. 'Then these last mentioned pistons will move to a great extent under the propulsion action of the expanding gases, the first set acting as the abutments and moving to a lesser extent. As piston 30 moves ahead on its propulsion stroke, it will force the previously exploded gases out of the exhaust 36, while the piston 31 is uncoverin said exhaust passage 36 and covers the in et 37. At the same time,'piston 32' is sucking in the ex plosive charge through the inlet 37 and this charge will e compressed between the pistons 3 and 32' on their. next movement of the p1sto ns. At the end of the compression action, 515(1011 32 will occu y the space now occupie by piston 32 an piston 31 will occupy the space now occupied by piston 32'. The movements of the pinions will be communicated to the thus to the shaft.

As will be seen, the action of the device is double, that is, there are two explosive ac-.

tions, two exhaust actions and two suction actions taking place at the same time.

A p1pe 39 connects the upper and lower portions of the water jacket together and a second pipe 40 connects the two side portions 0 the jacket together, the pi e39 belng provided with a discharge out et 41 which is adapted to be connected with the inlet of the pump, and the pipe 40 is provided with an inlet 42 which is connected with the outlet of-the pum Thus water is introduced into the water acket at the coolest oints of the motor and is taken from the acket at the hottest points thereof.
