Another object of the invention is" to sov arrange the buckets with respect to the gas nozzle that a practically continuous impulse is given to the wheel.

4@ther objects and advantages ofthe invent-ion will be apparent from the following description when taken in connection with the accompanying drawings, in which:

Figure 1 is a vertical sectionthrough'theI apparatus. f

Figure 2 is a transverse section taken on line 2 2 of Figure 1. Y

4Figure B is a fragmentary section taken through the wheel and one of the buckets.

Figure 4 isa fragmentary section taken on line l-Ll of Figure 3. Figure 5 is a side elevation, showing the exhaust ports, and

Figure 6 is a. perspective view of one of the buckets detached from the wheel.

Referring to the drawing more in` detail, the numeral 1 designates a water-jacketed casing mounted on a base member 2. The casing 1 is formed of two circular sections bolted together around the periphery, and adjacent the center is provided with a plurality of laterally extending exhaust passages 3.

Extending through the center of the cas` ing 1 is the main shaft 4l on which is carried the rotor 5. The rotor carries on its periphery a plurality of buckets 6. Six of these buckets are illustrated on the drawing, but it will, of course, be understood that this number may be increased or diminished as desired. rlhe buckets 6 are provided with the 'perforated lugs 7 by means of which they are pinned to the rotor. The buckets 6 have the same curvature as the rotor 5 andhave integrally formeel therewith the baille plate 8, which extends longitudinally of the bucket to a point adjacent the bottom thereof. The opposite end of the baille plate 8 is bent on a sharper curve than the main portion thereof and carries exterior' of the bucket the auxiliary baille plate 9 having a flared end portion. The rim 10 of the rotor 5 is formed with the radially extending grooves 11 for directing the exhaust gases toward the center of the casing,-whence they the atmosphere. l

Also mounted on the base member 2 is the combustion chamber 12 provided with ya water jacket 13, which envelops all but the may escape through the exhaust ports 3 to forward tapered portion 14 of the chamber.

An inwardly opening valve 15 is provided for admitting a mixed charge of gas and air from the carbureter; or, if desired, two

valves may be provided, one for gas yand the other for air.

The number 16 indicates a spark plug for explodingthe gas which enters through the valve 15. The exploded gases pass through the tapered portion 111 ofthe combustionl chamber and through the passage or nozzle 17 in the casing 1 tothe buckets 6 carried by the rotor wheel.y Itshouldbe here noted that after a short operation of the engine the portion 14 becomes suficiently hot to explode the entering gases and the current to the spark plug 16 may be cut olf.

Although only a single combustion chamber 12 and nozzle 17V are shown, it ,is not in* tended that the invention shall be so limited, as a plurality of such chambers is also contemplated in the practical operation of the invention.

In operation, the initial charge is exploded bythe Vspark plug 16 and the exploded gases are forced through the nozzle 17 and impinge on thev buckets 6. The expanding gases passl into the bucket to the bottom thereof and thence around the baffle plate 8. The gases are then divided by the plate 9 and directed into the passages 11 to the Acenter of the casing 1, where they may exexplosion an action somewhat analogous to a pulsometer occurs in the chamber 12. The exploded gases passing out of the chamber 12 cause a partial vacuum which opens the valve 15 and lets in anotlier charge, which is also exploded and impinges on the rotor buckets. By having thenozzle 17 rather long it Ais found that the friction of the gases against the wall and its inertia prevent any material back suction, so that the chamber l12 is almost entirely filled with` a new charge after each explosion. When properly adjusted, the explosions will take place at a high frequency and will thus give a continuous impulse to the rotor 5. f

While no compressor is shown in connecno n tion Withthe apparatus, it'is, of vcoursefobvious that one may be employed if desired.

From the foregoing ndescription `it will be seen that I have yprovidedan extremely simple turbine which is composed of few parts and is consequently light and inexpensive in manufacture and also onein Vwhich practically the entire force of the explosion c reacts on the. rotor.

In :accordance with the `patent statutes, I
