Abstract

18,349. Siemens Bros. Dynamo Works, Kieffer, E. O., Kloss, M., and Crowley, J. F. Aug. 3. Impeller blades; centrifugal-fan. The shallow blades c and long blades c<1> of a centrifugal fan are secured to the front and back plates b, by passing tongues p through slots in the plates, bending them, and welding them to the plates electrically. The tongues may be split, the parts being bent over in opposite directions before welding. The back plate is flanged outwards at the periphery, and the front plate is flanged at both edges as shown to increase the strength. The back plate is stamped out or spun to shape, and is secured to a hub d by welding, and also by tongues b on the long blades c<1>. The hub d is secured to the boss e on the shaft g by any suitable method, for instance by screws k, a nut i, and a pin s. In the ase of small fans, a flat turned in the back plate a may be secured directly to the boss e.
