CHARLES G. CURTIS, OF NEW YORK, N. Y.
ELASTIC-FLUID TURBINE.
SPECIFICATION forming part of Letters Patent No. 779,911, dated January 10, 1905. Application filed August 1, 1902. Serial No. 117,959.
To aZZ whom it may concern:
Be it known that 1, CHARLES Gr. CURTIS, a citizen of the United States, residing in the borough of Manhattan, city of New York, State of New York, have invented a certain new and useful Improvement in Elastic-Fluid Turbines, of which the following is a description.
The object I have in view-is to produce a simple and effective construction for the movable vanes of elastic-fluid turbines and for securing them in position upon the turbinewheel.
In the accompanying drawings, Figure 1 is a radial section at right angles to the shaft through the wheel-rim and centrally through a set of'movable vanes, and Fig. 2 is a radial cross-section through the wheel-rim and the several sets of movable vanes carried thereby.
l 1 are disks which form the web of the wheel, and 2 is the wheel-rim secured by bolts to said disks. The wheel-rim is cut with channels 3 on its outer surface, which channels receive the curved vane-bases 4. These vanebases are made in suitable lengths, a number of vane-bases occupying each channel in the Wheel-rim and together encircling the entire wheel. The movable vanes 5 are cut integral with the vane-bases 4 and project outwardly therefrom. The vanes are encircled by bands 6, which are also preferably made in sections. The vane-sections are secured to the wheelrim by bolts 7, which pass from the inside of the wheel-rim through the vane-bases, through cured to the vanes, and the vane-sections are rigidly secured in the channels in the wheelrim.
What I claim is 1. In an elastic-fluid turbine, the combination with a channeled wheelrim,of disks forming the web of the wheel and secured to the rim by bolts, vane-sections formed of curved vane-bases and vanes integral with such bases and projecting outwardly therefrom, and bolts passing through the wheel-rim, the vane-bases and the vanes and securing the vane-sections to the wheel-rim, substantially as set forth.
2. In an elastic-fluid turbine, the combination with a channeled wheel-rim, of vane-sections formed with curved bases at and vanes 5 integral with such bases and projecting outwardly therefrom, an encircling band 6, and bolts 7 passing radially through the wheelrim, the vane-base, the vanes and the encircling band, securing the band upon the vanes and securing the vane-sections to the wheelrim, substantially as set forth.
This specification signed and witnessed this 25th day of July, 1902.
CHARLES G. CURTIS.
