No. 874,432. Specification of Letters Patent. Patented Dec. 24, 1907.
Application filed May 3.1907- Serial No. 371.634.
T 0 all whom it may concern:
Be it known that I, HEINRICH PAUL RU- DOLF LUDWIG PoRsoKE, a subject of the a portion of a rotor with steam acting axially thereon; 2
shows a portion of a rot or with steam acting radially thereon, and Fig. 3 a modification of the rotor shown in Fig. 1,
As shown in the drawing the rotor is in each case so constructed that S-shaped blades 0; alternate thereon with shorter, straight blades 1), each of the blades 0 being bent at its ends to form troughs a and a The steam is directed into the troughs-a or a at such an angle that the diameter of the impinging jet is smaller than half-thev distance between two consecutive blades a. The purpose of the blade I) is to so. guide the steam that it does not enter the troughs a or a at the op osite side of the rotor."
In the ra ial flow turbine shown in Fig. 2 the S-shaped bladesa are bent into troughof the rotor and alternate with straight blades b. scribed with reference to Fig. 1. For driving the rotor anti-clockwise, steam is directed on to the inner circumference; for clockwise rotation steam acts in the opposite direction on the outer circumference o the rotor.
In the construction shown in Fig. 3 .the straight blades 1) are placed between the sides of the rotor the apertures for the entures for the outlet of the steam, so that expansion can takeplace between the blades.
What I claim as-my invention and desire to secure'by Letters Patent of'the United States is In a turbine the combination of S curved blades alternate'd'with straight blades of narrower width.
In witness whereof I have signed this specification in the presence of two witnesses.
