Abstract

810,834. Centrifugal separators. MANTER, F. Oct. 19, 1956 [Oct. 20, 1955], No. 30049/55. Class 23 [Also in Groups I and XXVI] In the ceiling fan shown, the driving motor is of the type having a rotary casing 23, and the conical outer casing 28 of the fan is connected to and rotates with the impeller blades 27 and the conical impeller hub 25. Insects and particles entering the fan inlet are directed centrifugally through holes 30 into the annular space between the casing 28 and a detachable cap 31.
