Specification of Letters Patent. Pgt t d'J 1 5 Application filed July 8, 1913. Serial No; 777,834.

Be it known that I, PONTUS OSTENBERG, av citizen of the United States, residingat'Los Gatos, in the county of Santa Clara and State of California, have invented a new and useful Internal-Combustion Turbine- Engine, of which the following is a specifi cation.

My invention relates to internal combustion turbine engines.

One object of 'myinvention is to provide v an engine in which the driving power is pro one w i h may be adapted to any purpose where wer is required.

' In the accompanying drawings, Figure 1 is a side elevation of my internal combustion turbine engine. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical section on line A-A of Fig. 2.-- Fig. 4 is a vertical 1 section on line BB of Fig. 2. Fig. 5 is a vertical section on line C-G of Fig.1. Fig.-

6 is a horizontal section on line DD of Fig. 2. Similar reference numerals designate corresponding parts in all the figures of the drawings.

R ferring more particularly to the drawings, my invention is described as follows The numerals land 2 represent the body portions of my invention, the samebeing .cast in two separate parts, and may be made of cast iron or any other suitable material and bolted together by bolts shown at 3. The upper parts of said body- portions 1 and 2 are cylindrical in form, of the proper length and proper diameter and are approximately Vertical in position. In the proper position near the upper ends of said cylindrical portions are ofl'sets cast therein shown at 4C. In

the top of said offsets 4 are placed a plurality of exhaust valves shown at 5. At the extreme top of said cylindrical portions 1 and 2 are shown intake valves 6, Which are for the purpose of admitting the explosive vapor taken in from any ordinary carbu reter. Said explosive vapor may be exploded by means of a'hot ball as shown atl', or any other suitable means. Try-cocks are show'n at 8, which'are for the purpose of designating the height of water in said cylindrical portions. l/Vater inlet'valves are shown at 9 "which are for the purpose of admitting Water to said'cylindrical portions, -1 and 2. The body portions 1 and 2 are cast in separateparts, the base-being in the form of a scroll as shown' at 10, Figs. 1 andf3, leaving a hollow space therein into which is placed a turbine wheel 11 said wheel being keyed. to-shaft 12, said shaft 12 resting in bearings 13. Inside of said base and 'in each section thereof are cast partitions. '14 "having-ports 1 5 slanting inwardly. through saidpartions as shown in Figs. 3, 5, and 6,

force of the water against the vanes 16 on turbine wheel 1.1, in either direc tion driving said turbine wheel ll'always in the same direction, said vanes 16 being supported by an outer rim 16. At the v and are for the purpose of directing the lower parts of said cylindrical portions- 1- and 2 is cast a port Said port is opened and closed by a valveshown at 18 and is for thepurpose of governing the speed of said turbine wheel 11. Said valve 18 is operated by any suitable connection attached to valve-' stem 19.

The operation of my engine is as follows :-The cylinders are filled with ,water through inlet valve 9 to the level of trycock 8. Amharge of gas is. admitted to the upper portion of each cylinder through any ordinary carbureter. The charge of gas in one cylinder is then exploded, said explosion forcibly driving the water downward in that cylinder and through all of the ports on that side of the turbine wheel, against the vanes of the turbine wheel and up through the ports in the scroll of the second cylinder. The body of water ascendingin the second cylinder compresses the gas in said second cylinder which, when exploded, drives the body of waterback through its ports against the vanes of the turbine wheel and back through the ports in the first cylinder. The

parts of this engine are so proportioned that When the water is driven from one cylinder by the gas explosion it causes a vacuum and afresh charge of gas is drawn in through inlet valve 6 to fill that portion of the cylin- 'der above the exhaust valves. When the water returns to the cylinder after each explosion it drives the exhaust out of said cylinder through the exhaust valves 5 until the water itself reaches and closes said valves 5 when the charge of gas in that portion of the. cylinder above the exhaust valves is compressed and exploded and the operation is alternately repeated. The gas and air mixture will not explode untilthe same has been compressed, and this compression does not occur until after the expanded gases have been discharged through valves 5 and the onrushing water has closed valves 5, continuing on upward to compression. Valves .5 are so balanced that they will lift just enough to allow the expanded gases to escape therethrough, andclose instantly when the water reaches them. lVhen the compressed gases are exploded by hot ball? the exhaust valves 5 are closed on their lower seats. As the water descends with force by said explosion it forms a vacuum which causes said valves 5 to take their upper seats, and by this same .vacuum a fresh charge of gas'and air mixture is drawn into the upper part of the cylinder above the exhaust valves 5 "through valve 6, operating alternately. It

is shown by experience that the expanding gases operating as above stated do not mix with the fresh charge drawn in to the upper 'part of said cylinders to any extent, as the exhaust valves 5 operate quickly and discharge the expanded gases without any loss of water through saidexhaust valves 5. To

reduce the speed of the turbine wheel the valve 18 is opened a distance and the supply of gas reduced thus driving a portion of the waterthrough the passage '17 with .reduccd force and diminishing'both the quantity and force of the water driven against the turbine, but not changing the compression in the upper part of the cylinder.

Having thus fully described my invention what I claim as new, and desire to secure by Letters Patent, is

1. In an internal combustion turbine engine the combination of twoicylindrical portions, means of fastening the same together at their base, means for admittmg water to 1 either direction,

arrears? turbine wheel continuously in the same direction, as shown and described.

2. In an internal combustion turbine engine of the class described, two cylindrical portions cast separate and having a base in the form of a scroll, and a hollow space therein into which is-placed a turbine wheel resting on and keyedto a turnable shaft,

said shaft resting in bearings 'in said base,

each-section of said base having a partition through which are cast ports slanting inwardly through which water is directed against-the vanes of the turbine wheel alternately ineither direction, driving said turbine wheel continuously in the same direction, said vanes on said turbine wheel being supported by an outer rim, substantially as specified.

3. Inaninternal combustion turbine engine of the class described, two cylindrical cast portions bolted together at their base in which is placed a'turbine wheel having vanes against which water is forced alternately in driving said turbine wheel continuously in the same direction, a passage connecting said cylindrical portions, said
