Abstract

216,969. McClatchie, S. March 20, 1923. Motors, cooling and ventilating; casings.-In a vacuum-cleaning apparatus comprising an electromotor and fan mounted in a casing of rounded form whereby it may readily be drawn over the floor following the movements of the flexible suction pipe which connects it with the suction nozzle, the exhaust current induces a cooling current of air over the motor. The motor, which is mounted within the rounded casing of the fan, carries on its rotarv armature 5 a disc 6 on which the curved' blades 7 of the fan are mounted. Air outlets 8 are formed in the casing on a level with the fan blades, which are separated from the filter chamber by a partition on the chamber or by a disc secured to the upper sides of the blades. A current of air is induced by the fan through apertures 9 around' the armature.
