throughout :5 indicates l' usually pi ter, upon any preferre casir or no i fo ming substai n' for devices niennted i Li a cylinder for l`he' cyli l .r 2 formed by the tions of the cas ne or housing is flat or cf reduced thickness ror the greater portion of its Drea, the outer portion thereof being inci; .sed7 as @vsn at 3 and designed s betantially rectangular in cross section. This outer portion of the cylinder indicated as 3, continues completely around the housing forming an annular enlarged space in which the gaseato be hereinafter referred. to, are received.

Mounted in the cylinder or housing 2., is a dislelike :intein-' which lits snugly between the walls of. the flat reduced portion of said cylinder and has formed on the outer pe ripheral edge thereof at predetermined points thereon one or more head members or the like which lit within the annular space of the latter. As many of these head members may be provided as are found desi rahle and thus the power of the device may be in creased accordingly and each of said head members is provided with a plurality of extension members 5', as clearly disclosed in Fig. l of the drawings. These. head members or project-ions 5 on the rotor Il afford a against saidk head members and said head` nien/rivers are beveled at their ends, as shown The outer faces of said head members contact snugly with the outer peripheral. wall of the enlarged portion 3 of said cylinder and carried on the central portion of the dislnlilre rotor a to project through openings in the sides or sections of the cylinder, is a shaft 7. .Il dziustahly mounted on the base orQ foundation l., on opposite sides of the cylinder, are the bearings 8 which ro. tataoly receive therein the projecting p0rtions of the shaft 7. As undue wear occurs between the sl ft, foundation and cylinder, the same may ne teiten up readily hy the adjustment of said hearings 8, as is obvious, and pulley is carried on one end of said shaft 7, whereby the power derived in the operation of the engine may bey transmitted to any desired device (not shown).

I have provided for the inlet of the eX- plosi-ve mixture or fluid pressure at the top of the cylinder or housing 2, at which point a pair of openings 9, arranged in spaced relation to one another, are provided. These form the actual inlet openings for the cylinder and a pair of the same are provided in order to provide for the reversing of the rotor, which will be hereinafter and more particularly set forth. Mounted on the housing or cylinder 2, over the openings 9, are the cylinders 10 which form feed cylinders, the same being independent of one another and hai'ing connection at points below the centers thereof, with a carbureter 11 of any preferred design. As shown in Fig. 8 of the drawings, the connections, between the carburetor and cylinders 10 may be provided with suitable valves whereby the supply of the gaseous mixture to the cylinders may be regulated as desired. Arranged in each of the cylinders lO in planes slightly below the centers thereof, are the dividing walls 12 which provide a pair of compartments in each cylinder and each division wall 12 is provided with a check valve 13, the purpose of which will be hereinafter and more particularly set forth. Hingedly mounted at the lower ends of said cylinders and opening downwardly through Y the openings 9 in the cylinder or housing 2,

are the plate-like Valve members 14. These plate-like valve members operate oppositely in order to permit one of the same to be in its inoperative position while the other is operating, and the side edges of said plate-like valves are provided with side flanges 15 projecting on both sides of the plate valve proper. These plate-like valve members .14 are designed to complete the formation of the annular space inclosed by the enlarged portion 3 of the cylinder 2 when said valve members are disposed to their closed positions and the outer side edges of these valve members 14 project slightly beyond the side walls of the enlargements 3 of the cylinders and lit in offsets 15 formed in the latter. This construction admits of the rotor being operated without interference with said valve members-and in view of the construction shown and described,y no appreciable amount of compression will vbe lost.

Loosely extending through the top wall 12 of each of the cylinders 10 is a rod 16, the lower end of which is pivotally connected to a link 1,7, the latter in turn being pivotally connected to the upper face of a valve'membcr 14. The upper ends of said rods 16 are removably secured to the hollow iston or plunger heads 18 which fit snugly mths cylinders 10 and coil springs 19 are cylinders.

tact at their lower ends with the lower walls of the hollow piston heads 18 and rigidly Secured at their upper ends to transverse pieces 20 secured to the upper ends of said The normal tendency of these springs is to force downwardly upon the piston heads, which operation will obviously cause the valve members 14 to be opened and an adjusting means 21 is provided in connection with the pieces 20 and the upper ends of said springs, whereby the tension of the latter may be adjusted. Inasmuch as but one of the valve members 14 may be operated at a time, a means is provided for retaining one valve member in .its closed position at all times. This is accomplished by means of a rocking arm 19 which is mounted at the upper ends of said cylinders, the ends of which are indicated as 19a, project over the respective cylinders. Hook members 19b are carried on the pistons 18 which are adapted to be engaged with the ends 19, one at a time and as shown in Fig. 6 of the drawings, one piston head 18 is 4hooked in its inoperative position, while the other is operated.

It will be understood that as the rotor is revolved in the housing or casing2, the head pieces or projections 5 thereon are adapted for contact with the depending or open plate-like valve.14, to force the same upwardly to its closed position. As the same is forced to its closed position, the rod 16 will be forced upwardly and the springs 19 compressed. As the rod 16 is forced upwardly, the plunger or piston head lo thereon will also be raised and in so doing, a charge of gas will be received in the cylinder 1() from the carbureter 11.

As soon as the projection Ior head piece 5 passes the opening covered by the valve member 14, said valve is forced by the pressure of the gas within the cylinder 10 and the action of the spring 19 to its open position. As the valve is opened, the piston or plunger head 18 will also be forced dmvnwardly to compress the gases against the division wall 12 and such compression will also open the check valve 13 and permit said gases to be released to the lower compartment of the cylinder 10. In this lower compartment of the cylinder 10, at the lower portion thereof, is mounted a spark plug 22 which is connected to a sparking apparatus (not shown) in the usual or any preferred manner. The device is so timed that the compressed gases which are forced into the lower compartment at this particular time will be fired and the force of the explosion directed against the adjacent face of the head or projection 5 on the rotor 4 which, at this time, is at a point immediately adjacent the valve member 14. The space inclosed between the one face of theprojection or head member-5 on the ro tor and the valve member-14, when the latter is in its lowered position may, for convenience, at the time of the explosion, be termed a firing chamber and is indicated as 23. It might here be stated that this sparking device is timed according to the osition of theV piston or plunger head 18.

n order to carry out this purpose, a projection 23 is provided on the transverse piece '2O of each` feed cylinderwhich has fulcruined thereon, a rocking arm 23. One end of the rocking arm is connected by means of a linlr 23" to the piston head in the adjacent cylinder and the other end of the rocking arm is connected by means of linking arm 23e to any desired operating means (not shown) for cooperation with the sparking device.

The force of the explosion will, of course, be directed against the beveled face of the head member or projection 5 on the rotor to cause the latter to be revolved. The gases and other products of combustion will be carried through lthe space inclosed by the` enlarged portion 3 to a point on the device immediately opposite that in' which the openings 9 are provided. An exhaust 2% is provided in the base l which communicates with the annular space at such point and aords an outlet for the products of combustion and burnt gases. This operation may be continued and when it is desired to reverse the operation of the rotor, the rocking arm 19 is disengaged from the one iston head 18 to which it was engaged previously and rocked to the opposite position, and

linked or hooked into engagement with the piston head 10 which was previously in operation. The explosionswhich'will now take place in the device will be directed against the opposite 4faces of therotor projections or heads 5 to cause the rotor to be rotated in the opposite direction. The device will be actuated in identically the same manner as before but the direction thereof will be reversed.

The usual oiling devices and a Water jacket may be provided for this engine, if desired. sary, a governor may also be used in connection with the device.

While I have shown and'described my de vice particularly adapted Afor use in connection with a carbureter, wherein explosive gases are supplied to the feed cylinders of the device, it will be understood that the same may be operated through the medium of various other forms of fuel. Fluid pressure is equally well adapted for use in connection with this device and, of course, under these conditions, certain features of the device may be omitted. The device as shown, however, particularly Well adapted' for use with a powder mixture andit- 'will be If it is found desirable and necesunderstood that any form of explosive may be used in connection therewith.

From the foregoing it will be seen that I have provided a device which is simple and durable in construction, inexpensive to manufacture and one which will be very eHicient and useful in operation. Vhile I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes inform, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.
