REVERSIBLE TURBINE.
SPECIFICATION forming part of Letters Patent No. 758,595, dated April 26, 1904.
Original application filed December 6, 1902, Serial No. 134,208. Divided and this application filed November 27, 1903. Serial T0 at wlemw it mayconvern:
Be it known that I, CHARLES FERDINAND DE KIERzKowsKI-STEUART, a subject of the King of Great Britain, and a resident of St. Stephens Club, Westminster, in the city of London, England, have invented certain new and useful Improvements Relating to Reversible Turbines, of which the following is a specification.
Turbine-wheels which are driven by a jet or jets of steam or other motive fluid are usually capable of rotation in one direction only.
The present invention, which has been described in application Serial No.-134,208, filed December 6, 1902, of which the present application is a division, has reference to an arrangement by means of which a turbinewheel may be made reversible. To this end I provide a symmetrically-constructed turbine-wheelr that is to say, one which can be equally-well acted on either wayand a deflecting device by which the jet or jets may be pointed in either direction.
In the accompanying drawings, Figure 1 shows in plan view a turbine-engine embodying my invention, the cover of the wheel-casing being removed. Fig. 2 is a section on the line A B of Fig. 1, and Fig. 3 is a sectional plan illustrating the deflecting device.
s is the wheel-casing, and t is the wheel mounted therein. This wheel is preferably of the construction shown in the drawings, in which case it consists of an outer cylindrical shell Q0, which may be wound round with wire of high tensile strength and is mounted on the engine-driving shaft 0. -An annular frame a, fitting into the frame w, forms an annular (No model.)
through channel or passage. passage 24 is intersected by a large number of fine wires 00, closely spaced. Immediately opposite the jets, where they enter the wheelcasing, are arranged deflectors y, which are capable of being shifted, as shown in Figs. 1, 2, and 3. The deflectors y are intended to guide the jets at a suitable angle into the annular wire-intersected passage of the turbinewheel, through which the Working fluid passes in a helical course to the exhaust-passage 2, leading to a condenser or the outer air.
The movable deflectorsare arranged in oppositely-inclined pairs (see Fig. 3) in a double ring 1, capable of sufficient rotary movement to bring one or other set of deflectors to act upon and divert the incoming jets in one direction or the other. Rotary movement is given to the ring 1 by means of an eccentric 2 and link 3. (See Fig. 2.)
What I claim as my invention, and desire to secure by Letters Patent, is-- In a turbine-engine the combination with a deflecting device for the jet and means for moving said device to point the jet in either direction, of a reversible turbine-wheel comprising an inner and outer shell and an annular channel closely spaced with intersecting wires, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
CHARLES FERDINAND DE KIERZKOWSKI-STEUART.
