To all whom it may concern:

Be it known that Lorne ILDEvnn'r Pom- HEUR, citizen of the French Republic, residing at' Meru, Oise, France, has invented certain new and useful Improvements in Explosion Rotating Engines, of which the following is a specification.

This invention relates to improvements in rotary explosion engines, and the object of the invention is to make a simple rotary engine driven by the explosion of vapor charged air and one that will be inexpensive to build, very light, and efficient in operation.

Another object of this invention is to provide an engine of the above type in which the parts are relatively few and simple and whose operation is very easily understood and controlled.

Another object of this invention is to provide such an engine that is compact in structure, readily and easily installed and effective and reliable under almost any condition of o ration. Other ob ects will be obvious from the following escription, taken in connection with the drawing, which forms part of the specification.

In the accompanying drawings:

Fig. 1 is a vertical section through the rotating engine on the line of the drive shaft.

Fig. 2 is a section on the line A, B, C, D, E, F, Fig. 1.

Fi 3 is a section .on the line A, B, G,

ig. 6 is a detail 5 owing the pawls and pawl slots associated. with the cylinder cas- Fig. 7 is a view of the arts shown in Fi 6, lookingat right ang e thereto.

Fig. 8 is a perspective view of one of the p The engine is provided with a circular composed of parts 1- and- 2 bolted '50 toget or by means of bolts 3. 'ILhese parts thus fastened together forma circular annular cavity or space 4 constituting the cylinder of the engine. Passin through the center of the casing in openings provided therefor is a rotating shaft 5. Between the shaft andthe bearing walls of the casing are interposed ball bearing anti-friction means 6 and 7, and between shoulders on.

32. The disk 23 is permanently attached tothe inside wall of section 2 and is provided with cam rooves 20, 21 and 22, shown more clearly in ig. 2. The disk 32 is provided with radial grooves 31, as shown in Fig. 6. The disk 12 is permanently attached to the shaft 5 and rotates between the disks 23 and 32. On the face of disk 12, adjacent to disk 23 there is provided a series of radial grooves 17 in w ich are located pawls 18,

as shown in Fig. 4. Each of the pawls 18 has a projection 19 fitting into one of the cam grooves in disk 23. On the face of disk 12 adjacent to disk32 is series of cam slots, as shown in ig. 3. In

each of the radial grooves 31 of disk32 is located a pawl 30. This pawl 30 is pro vided with a projection 29 which engages one of the cam slots on the face of the disk 12. Within the annular groovecylinder 4 are located a plurality of disk pistons 13, 14, 15 and 16 which are ada ted to move with in the said cylinder. ach of these pis: tons is provided with a socket 25 adapted to be engaged by the pawls 18 and 30. The

engagement of these pawls 18 and 30 with.

the sockets 25 is determined by the cam slot on the disk 23 and the disk 12. .The cam slots in the disk 23 and the disk 12 are so arranged in relation to the pawls thereon as to control and'properl time the engage. ment of the pawls wlth. t e pistons. It will be readilyseen that whenever any pawl 30 rovided a a socket the corresponding .piston' on is in fixed. relation to the cas n. It

will also be noted that when any pawl 18 engages a socket 25 the corresponding piston will be rotatively attached to the disk 12 and thereby to the shaft 5. For the pur pose of admitting fuel into the Cylinder 4 is an admission pipe 33 connected with a suitable carburetor. There is also connected to the cylinder an exhaust pipe 34 and a spark plug 36.

For an understanding of the operation of this device attention is called to Figs. 2 and 3. As shown in Fig. 2, the pistons 14 and 16 are movable with the shaft 5 due to the engagement of the pawls 18 in the socket 25, while the pistons 13 and 15 are held fixed in relation to the cylinder by means of pawls 30 and socket 25. These pawls 30 as previously mentioned move in slots in the disk 32 permanently secured to section 1 of the casing. In the position of the parts shown in these figures the cylinder between the pistons 14- and 15 is filled with an explosive mixture which is undergoing compression due to the rotation of the piston 14 within the cylinder. As this piston .14; advances due to the explosion which has taken place in the fuel previously compressed between pistons 15 and 16, fuel is taken in through the feed pipe 33 between pistons 13 and 14, at the same time the fuel that has been previously used by explosion is being exhausted from between the pistons 16 and 13 out through the exhaust pipe 34. As the pistons 14 and 16 rotate due to explosion, the piston 1 will assume a position about where piston 15 is in the drawing. Just before the piston 14 reaches the present position of piston 15 the pawl 30 is released from the socket 25 of piston 15 and one of the pawls 18 engages said socket due to the motion of the pawl projection in the slot 22, whereby the piston 15 is moved to a position about where the piston 16 now is, after which the pistonls assumes the position of piston 15 in Fig. 3 and is locked in that position by one of the pawls 30. At the time this relatively changed position is taking place between pistons 14 and 15, piston 13 has been moved to the position of is and the piston 16 has moved to the present position of the piston 13. These changes are regu lated by the engagement of the pawls 18 and 30 with the socket 25 and such engagement is determined by the particular shape and location of the different cam slots in which the pins of the pawis engage. Fr an observation of the shape of these siot it can be readily seen that the engagement any of the paivls with the socket m pends upon what part of the siot t at any time iocat-ed. justing Applicant does not wish to be limited to the specific embodiment of his invention as here illustrated, which may be considered only as a preferred form, but only wishes to be limited by the scope of the appended claims.
