Abstract
853,331. Axial-flow pumps and blowers. VASILJEVIC, K. July 25, 1957, No. 23544/57. Class 110 (1). An impeller for a pump, blower or the like .comprises two discs forced together by a central clamping device so as to clamp the blade spindles between correspondingly shaped sockets at the outer rims of the discs. The impeller shown comprises discs 1, 2 of pressed sheet metal, formed with sockets 3 to receive the blade spindles 15, and strengthened by rims 4. Each spindle 15 has a collar 6 which extends through recesses 7 in the sockets 3. After the blades have been set to the required angle, the discs 1, 2 are drawn together by means of a nut 11 threaded on the impeller hub 8 so as to clamp the spindles 15 in the sockets 3. Some of the blades may be omitted, and the vacant sockets may be closed by plugs. The blades may be of plastics. In a modification the discs are cast, stamped or moulded from aluminium or plastics.
