Application filed October 15, 1915; Serial No. 56,051.

Engines, of which he following is a specication.

My present invention relates to improvements in the art embracing internal combustion engines, and more particularly to a specific type ofrotary motor which can be operated at anabnormally. high speed and which will develop a maximum degree of power and eflicienc The object of my present invention is to provide such a motor, extremely simple in construction and of few parts, and one that will run smoothly, and in which friction is reduced to a minimum.

Another object resides in the provision of a rotor journaled within a water-jacket, said rotor being of smaller diameter than the jacket and disposed therein similar to a rotatable spool. A disk or fin integral with the water-jacket extends intermediate the two flanges of the rotor, and serves to divide the same into cylinders.

Having these and other objects of general utility and design in view, I- have, illustrated a preferred embodiment of my invention in the accompanying drawings, in which Figure 1 is a 11 of Fig. 4.

Fig. 2 is a view at right angles to 1.

Fig. 3 is a fragmentary section showing the arrangement of the intake ports.

Fig. 4.- is a transverse section on line H of Fig. 1.

Fig. 5 is a view of the rotor from the casing of the motor.

Fig. 6 is a schematic view showing the relative arrangement of the valves.

vFig. 7 is a similar view the valves being in their extreme outer position from that as shown in Fig. 6.

Fig. 8 is an enlarged fragmentary detail elevation of one of the abutments, and

Fig. 9 is a transverse section therethrough disassembled I on line 9-9.

Similar reference characters referrespectively to similar parts throughout the several views.

y invention consists in providing a substantially cylindrical water-jacket 10, which cross sectional view on line .tor. The exhaust port is mounted upon the usual base 11, with a vertical centrally disposed web or fin 12, integral therewith and substantially dividmg the interior of the jacket 10, or chamer, into two similar compartments, in this case, to-form the opposed cylinders of my engine.

The rotor of my stantially spool-shaped member, 13, and 1 a swinging piston '19, surface of which is also provided with suitable packing 20. Into the respective cylinders leads a fuel intake, 21, and leading therefrom an exhaust port,

stantlally adjacent the abutments, 16, I lead a spark plug, 23 with suitable electrical connections, not shown, but so timed as to spark when the parts are in a position as shown in Fig. 6.

From the foregoing it will be apparent the surfaces of the pistons forming abutments, and ignition of the gas taking place at this point, the pressure will be applied against the pistons, thus revolving the rois positioned at substantially 45 degrees from the intake, so that the burnt gases are driven forward of the rotating swinging pistons, 19, and forced out from the compartment. 0

erein I have shown and described my invention for use in connection with an explosive gas, I wish it understood that the same principle may be advantageously em bodied in a motor employing steam as a motive power.

What I claim is 1. A rotary engine comprising a cylin-- drical com artment havin intake and ex- 16, is radially forming the cylinde: heads, opposed compartments, one on the outer face of each flange, a swinging piston pivoted in each compartment, and a partition integral with said cylindrical compartment and having an abutment thereon engaged by said swinging pistons.

'2. A rotary engine comprising a cylindrical compartment, a centrally disposed web having a radial abutment thereon, said web dividing" the compartment into two similar apartments, each apartment being provided with an inlet and exhaust port,

a spool-shaped rotor journaled in the web and a swinging piston pivoted on each flange 01": said rotor, the flanges of said rotor forming the heads of the respective cylinders.

in testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two subscribing witnesses.
