Abstract

14,104. Kerr, C. V. June 17. Impellers in parallel; casings; impeller blades; screw fans.-A shaft 1 carries two impeller disks 2 which work in parallel, drawing air through the inlet openings 8 and discharging it into a volute casing 5 either directly, Fig. 1, or through a constricted annular passage 40, Fig. 3. The impeller disks or hubs 2 are connected by a deflector 11, which surrounds the shaft and may take various forms, such as a double conoid, Fig. 1, or a cylinder 30 and disk 31, Fig. 11. The impeller blades 3, Figs. 5 and 6, have a uniform twist from tip, Fig. 7, to base, Fig. 8, and are provided with enlargements 3<a> fitting in suitable recesses in the hubs. Waste of oil is prevented by providing the bearing-boxes 4 with stuffing-glands secured by screws.
