7 To all whom it may concern:

Be it known that I, LOUIS HACHENBERG, a citizen of the United States, and resident of the borough of Bronx, in the city and State of New York, have invented a new and useful Improvement in Turbine-Engines, of which the following is a specification.

My invention consists in certain improvements in that type of turbine engine which is shown, described and claimed in my Letters Patent Nos. 801585 and 801586, dated October 10, 1905; No. 823526, dated June 19, 1906; and No. 877502, dated January 28, 1908. r

One object of this present invention is to provide certain novel features in the constructlon and arrangement of the several parts of the englne whereby the motive fluid is passed inwardly and outwardly throughthe vanes of the stationary and rotary members, a plurality of times during one revolution of the rotary member whereby the efficiency of the engine is materially increased, the path being arranged in easy curves so thatthe flow of the motive fluid is deflected as' little. as possible from a straight line during its passage through the machine thereby eliminating all fluid pressure shocks and not impairing the velocity of the motive fluid other than that absorbedby the moving vanes, the velocity of the fluid being never converted into pressure from the motive fluid supply chamber to the exhaust chamber. Another object is to provide means for relieving pressure in the idle portion or portions of the machine and to utilize this relieved pressure at another portion of the machine. In all partial admission turbine engines, owing to the idle portions of the machine, there is a tendency of the fluid pressure equalizing itself through leakage at the; clearance spaces. tendency to increase the pressure due to the moving vanes carryingadditional motivefiuid along with them. This causes a great disturbance of the fluid during the idle portions and also at the points where'the di turbing pressure in the moving vanes comes in contact with a succeeding portion ofthe motive fluid path through the vanes. To overcome these faults, a channel is provlded in the sta- Specification of Letters Patent.

-tionary member between its separated groups of vanes, said channel leading from one portion of the fluid pathto another portion thereof so that the pressure is removed from the moving vanes as they leave one portion of the path and this relieved pressure is again directed against the vanes as they enter another portion of the fluid path. This pressure taken from the moving vanes has velocity and direction similar to that of the motive fluid and thus causes no interference with the flow of the motive fluid but adds additional-effect to the turbine which otherwise would be entirely lost.

A practical embodiment of my invention -is represented in the accompanying drawings, in which Figure 1 is a transverse section through the engine in the plane of the line A-A of Fig. 2, looking in the direction of the arrows, and

Fig. 2 s a longitudinal central section through the engine taken in the plane of the line lil3 of Fig. 1 looking inthe direction of the arrows.

, The engine represented herein is shown asbeing provided with two coacting sets of stationary and rotary members. One set only will be specifically described together with their adjacent parts, it being understood that any number of sets may be employed.

The engine shaft is denoted by '1 and it is mounted in suitable bearings 2, 3, of the cylinder heads 4: and 5. The lower half of the cylinder wall between the heads 4: and 5 is denoted by (3 and the upper half by 7. lVithin the cylinder I have shown two sets of rotary and stationary members. Each stationary member is denoted by 8 and its rotary member by 9., lhe rotary member is fixed to rotate with the shaft 1. The rotary member is provided with one or more annular series of vanes 10, in the present instance fluid supply chamber is denoted b 13 and is provided with one or more nozz es 14 arranged to direct the motive fluid inwardly through the vanes at this point.

A passage 15 is arranged to receive the tionary and rotary members and I donot I Wish to limit myself to the 'number of times motive fluid as it passes inwardly from the supply chamber 13 and direct it outwardly through the vanes at another point.

A passage 16 is arranged to receive the motive fluid as it passes from the passage 15 and direct the motive fluid inwardly through the vanes at another point.

A passage 17 is arranged to take the motive fluid as it leaves the passage 16 and direct the same outwardly through the vanes at' still another point.

The motive fluid exhaustchamber 18 is ar-' ranged in position to receive themotive fluid from the passage 17 and convey it to any.

' chamber.

It will be seen that the motive fluid is more than once that the motive fluid is caused to pass inwardly and outwardly through said vanes.

While I have described the means for relieving the pressure on the vanes of the rotary member at their idle portions in connection with the machine shown herein, I do not wish to limit its use to the particular machine herein shown but contemplate its use in connection with any partial admission turbine engine.

What I claim is p 1. A turbine engine comprising a stationary member having a plurality of annular series of vanes and a rotary member having a plurality of annular series of vanes coacting with and in the same plane as the stationary vanes and means for directing the flow of the motiveffluid inwardly and outwardly through the several series of stationary and rotary vanes a plurality of times during one revolution of-the rotary member.

2. A turbine engine comprising a station- .ary member having a plurality of annular series of vanes and a rotary member having a. plurality of annular series of vanes 'coacting with and in the same plane as passed inwardly and outwardly a plurality of times, in the present instance'twice inwardly and twice outwardly through the vanes during one revolution of the rotary member, or, in other Words, that the motive fluid is caused to impinge against the vanes four times during one revolution of the rotary member.

To eliminate the back pressure upon the vanes of the movable member during their idle portions, I- provide the blank portions 12 of the stationary member from the motive fluid supply chamber to the exhaust chamber'with groups of channels 25, 26,. 27, the channels 25 being arranged to relieve the pressure from 'the vanes 10 of the rotary member as they leave the first portion of the motive fluid. path and direct such pressure against the .vanes as they enter 4 the second portion of said path. The channels 26 are arranged to takethe pressure 'from the vanes of the rotary member as they leave.

the second portion of the path and direct it against said vanes as they enter the third portion of said path. The channels 27 are arranged to take the pressure from the vanes of'the movable member as they leave the third portion of the motive fluidpath and direct the. same against the vanes as they enter the fourth portionof said patlf. I do notwish to-limit myself to the numberof annular series of-vaneson the sta-.

the stationary vanes, a motive fluid supply chamber arranged to direct the motive fluid inwardly through the stationary and rotary series of vanes, a passage arranged to receive the fluid as it passes inwardly from the vanes and direct the fluid outwardly through said vanes at another point and a larger passage arranged to receive the fluid as it passes outwardly from said vanes and direct the fluid inwardly through said vanes at another point and a still larger passage arranged to receive the fluid as it passes inwardly from said vanes and direct the fluid outwardly at another point through said vanes and an exhaust chamber arranged to receive the fluid as it passes outwardly from said vanes.
