The shaft E also able distances apart.

The two cylinders are secured to any suitable foundation and remain stationary while the engine is at work.

High-pressure steam is admitted to the cylinder A through the inlet-passage and passes into the two chambers G, thence through the inclined jet-holes 'into the chambers z'. The jets of steam revolve the wheel by impact against the bottoms or pointed portions of the chambers and also by impact against the abutmerit-plates, against which they impinge after passing through the holes 7'. After the steam has impinged upon the abutment-plates H it passes from the cylinder Athrough the holes f, the passage e, and the holes f into the chamber 7c of the low-pressure wheel B. The steam then expands further inside the low-pressure Wheel and impinges against the abutmentplates p in its passage from the chambers m of the low-pressure wheel to the exhaust-passage of the low-pressure cylinder, and in this manner the driving-shaft of the engine is revolved continuously.-

What I claim is 1. In a turbine-engine, the combination, with a high-pressure wheel having chambers at its periphery, a shaft having the said wheel secured on it and provided with a longitudinal steam-passage, and a low-pressure wheel also secured on the said shaft and provided with chambers at its periphery and passages between the said chambers and the said steampassage; of a cylinder forthe said high-pressure wheel provided with a steam-inlet passage at'its periphery for admitting steam direct to the said chambers of the high-pressure wheel, the exhaust-space of the said cylinder being connected with the said longitudinal steam-passage, a cylinder for the said lowpressure Wheel provided with a steam-outlet, and a distance-piece arranged between the said cylinders andforming a bearing for the said shaft.

2. In a turbine-engine, the combination,

with a high-pressure cylinder, a low-pressure cylinder, and a distance-piece between the two said cylinders, said cylinders being formed in halves and the distance-piece being formed integral with the adjacent halves of the said cylinders; of a shaft journaled in the said distance-piece and provided with a longitudinal passage, a high-pressure wheel and a lowpressure wheel secured on the said shaft inside the respective cylinders, said Wheels and cylinders being provided with suitable steamchambers and passages which communicate with the said passage in the said shaft.

3. In a turbine-engine, the combination, with a high-pressure cylinder provided with circumferential steam-inlet chambers at its sides having inclined jet-holes, and abutmentplates at its periphery between the said chambers; of a wheel journaled in the said cylinder and provided with a series of V-shaped chambers which communicate with the said jet-holes, said Wheel having also a series of inclined jet-holes which conduct the steam from the said V-shaped chambers to the said abutment-plates.

4:. In a turbine-engine, the combination, with a low-pressure cylinder provided with abutment-plates at its sides; of a shaft projecting within thesaid cylinder and provided with a longitudinal steam-passage, a low-pressure wheel secured on the said shaft and provided with an internal chamber communicating with the said steam-passage, and a series of V-shaped chambers arranged between the abutment-plates and communicating with the said internal chamber, and means for exhausting the steam from the said low-pressure cylinder.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM WYAND.
