UNITED STATES PATENT OFFICE.
HANS WAGNER, OF GREVENBROIOH, GERMANY, ASSIGNOR TO MASOHI- NENFABRIK GREVENBROIOH, OF GREVENBROICH, GERMANY.
STEAM-TURBINE.
Specification of Letters Patent.
Patented Oct. 17, 1905.
Application filed July 6, 1905. Serial No. 268,487-
l'0 all whom it may concern.-
Be it known that I, HANS WAGNER, a subj ect of the Emperor of Germany, residing at Grevenbroich, Rhine Province, in the Empire of Germany, have invented certain new and useful Improvements in the Rotating VVheel-Blades in Multitier Steam or Gas Turbines, of which the following is a specification.
In an application for a patent, Serial No. 252,450, filed by me March 28, 1905, for multitier steam or gas turbines, in order to allow of the angle which the direction of ad mission and discharge of the fluid in the guide-blades forms with one another being less than one hundred and eighty degrees the rotating wheel-blades are arranged either in parallel mutually-facing planes of the ring of blades or in similar concentric cylindrical surfaces. In order to diminish as far as possible the curvature and length of these conducting-blades, I now arrange the rings of blades in such a way that the generatinglines of their surfaces are mutually inclined at an angle which is less than one hundred and eighty degrees. In these rings the rotating wheel-blades, which reverse the direction of the steam, are suitably introduced or worked in.
Such an arrangement is shown in the accompanying drawings, in which- Figures 1 and 2 are vertical sections of a portion of the turbine, showing the blades.
According to Fig. 1 the blades 1) and b, which reverse the direction of the steam, are arranged with two conical faces a a, the generating-lines of which here inclose an angle of ninety degrees. The steam enters,
through a nozzle 0, the blades l) of the rotating wheel and is by them transmitted through the guide-blades d to the rotating wheelblades 7). position of the blades in the ring of blades a and a these conducting-blades d are extremely short, so that the deleterious frictional course through these blades is reduced to a very small amount. As in the arrangement described in my application, Serial No. 252,450, here also the angle at which the direction of the steam is altered in the conducting-blades is considerably less than one hundred and eighty degrees, the loss of en-. ergy in the conducting-blades is considerably diminished.
In Fig. 2 the rotating wheel-blades b and b, reversing the direction of the steam, are arranged in annular areas a a, one of which lies radially, the other cylindrically to the axis of rotation. Here also the angle of curvature of the conducting-blades d is considerably less than one hundred and eighty degrees and the steam course an extremely short one.
I declare that what I claim is In a multitier-turbine, the rotary wheelblades 1), I) having faces a, a, placed at an angle of less than one hundred and eighty degrees, combined with the conductingblades d, located between said wheel-blades and forming an angle also of less than one hundred and eighty degrees, as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
HANS WAGNER.
