Abstract
14,836. Roots, J. D., [Rankine, A. E., Tilleke, R. E. G., and Brighouse, S.]. June 27. Impeller blades, screw fan &c. Relates to screw propellers, fans, pumps, or motors with blades mounted in multiple sets on a shaft, and consists in using blades cut from flat rings or cast with a slight curve, one set being secured to the shaft and carrying a number of blades of like number superposed and secured thereon in such a manner that each outer blade is rigidly secured at a point between its end to the corresponding inner blade so as to leave open spaces. Further, the inner diameter of the outer blades is approximately equal to the outer diameter of the adjacent inner blades. The propeller shown has three inner blades B attached to the shaft, and further sets C, D, E secured, at increasing angles to the shaft, to the blades B, the points of attachment being along radial lines F. When used as a pump, the last set of blades may be arranged at a negativeangle, and the complete member is enclosed in a pump casing which may have one set of stationary guide blades on its inner surface and immediately surrounding the rotating blades. The peripheral delivery passage in the casing may be of progressively increasing area in cross-section.
