Specification of Letters Patent.

Patented Aug. '10, 1920.

1 Application filed October 4, 1919. Serial No. 328,490.

To all whom it may concern:

Be it known that we, ISAAC SANTOS Y SUAREZ and ROBERTO on AROZARENA Y MEN- of compressed and burnt gases to pistons rotating within a casing or chamber and as these pistons are connected to a central shaft by means of a wheel, this shaft will also rotate.

This machine, owing to the mechanism which we desire to have patented, has the four strokes of the ordinary four-cycle engine, i. 6.. suction, compression, explosion and exhaustion.

With reference to the accompanying drawings, in description and explanation of our improved mechanism, the object of our patent:

Figure 1 is a side view of the motor;

F ig. 2 is a vertical section thereof, taken approximately onv the line 22 of Fig. 4;

Fig. 3 is a vertical transverse section, taken approximately on the line 33 of Fig. 1; and,

. Fig. 4 is a plan yiew of the motor. b Thce) pistons g, h, z, rotate within achamer (Figs. 1,. 2, 3,) and this wheel is attached to the central shaft 1, (Fig. 3). When the pistons rotate, the wheel 12, and the shaft 1, also rotate and to this latter, gear 2, and cams 3,-and 4, are connected, (Figs. 1, 2, 3). The-gear. 2, when turning, moves pinions 7 and 8 (Fig. 1) by means of a chain, andthese plnions give movement to the cams 9, 10, 11, and 14, which open the valves 0, (Z, c, and f, (Figs. 1, 2, 4). The springs, fastened to the stems of these valves, close them when not held open by the cams. The cams 3, and 4, open the slide-valves a and b, and the springs fastened to them close the valves when not held open by the cams. The slide valves (1, and b, (Fig. 5,) when not opened by the cams, close chamber 0, completely,

and, when opened, leave free Way to the.

pistons g, h, i.

and are secured to the wheel 12,-

The operation of the motor is as follows:

When the piston g, rotates in the chamber 0, in the direction 9, h, 2', shortly after it reaches the slide-valve a, this valve closes and valve e, opens. This valve is connected with a carbureter by the tube K, and as the piston g, advances in the chamber 0, and the slide-valve a, being closed, the piston g, sucks the gas-from the carburetor, through the valve 6, and the opening 727., into the chamber 0. Shortly before the piston g,

reaches the slide-valve I), this valve opens and remains open until the piston has passed when it closes again. The valve e, also closes and the gas is in the chamber 0, between the slide-valves a, and b, then the piston i, is near the slide-valve a, which opens and the piston begins to compress the gas which is in the chamber 0, against the slidevalve '6. The valve d, then opens and the compressed gas passes through the opening 1', and the valve d, to the tube J In the meantime, piston 2' advances and as soon as it passes the opening 2, through which the valve 0, is in communication wlth the chamber O, the valve 0, opens and the compressed gas which is in the tube J, passes to the chamber 0, between the slide-valve a, which is closed, and the back part soon as the compressed gas has passed the valve 0, closes and there is an electric spark from the spark-plug that is placed in the opening 9, which causes combustion of the .compressed gas in the chamber 0, between of piston 2'. As v ber 0, full of burnt gases The slide-valve b, is closed and the valve 7, then opens, which valve is connected to the chamber 0, through the openings, and the piston h, expels the burnt gases through the valve f, and the tube Z. As soon as the piston passes the slide-valve a, this closes and the valve 6, opens and the piston it, begins to suck the gases from the carburetor through the tube K, and the operation continues so on successively.

The pistons g, h, i, and the slide-valves .a,and b, have expansion springs of a recchamber, a shaft mounted for rotation in said casing, a plurality of members secured tosaid shaft and adapted to traverse said thereby to form an explosion chamber annular chamber, a pair of members adapted to slide radially of said annular chamber,

within said annular chamber, said explosion chamber being provided with a plurality of valve-controlled inlet and outlet passages, communicating means between one of said inlet passages and one of said outlet passages, and means for operating the slidable members and valves'in proper sequence for admitting an explosive charge to said explosion chamber during the passage therethrough of one of said traversing members, and for establishing communication between the said communicating inlet and outlet passages during the passage of another of said traversing members through the explosion chamber.

2. An internal combustion engine as set forth in claim 1, the valve-operating means comprising a plurality of cams mounted for rotation on said casing, and a wheel secured to said shaft and adapted to cause rotation of said cams.

3. An internal combustion engine as set forth in claim 1, the means for operating to said shaft and adapted to cause rotation of saidcams, and the means for operating the slidable members comprising a pivoted lever secured to each of said slidable members and cams secured to said shaft and adapted to swing said levers on their pivot.

In testimony whereof we have signed our names to this specification.
