Abstract

472,676. Vacuum cleaners. NAAMLOOZE VENNOOTSCHAP RADIOFABRIEK & INGENIEURSBUREAU VOORHEEN VAN DER HEEM & BLOEMSMA. Feb. 13, 1937, No. 4339. Convention date, Feb. 15, 1936. [Class 8 (i)] In order to minimize the operation noise the horizontal housing 1 in which the motor-fan unit is mounted is given such a form that the air currents do not suffer sudden changes in direction. For this purpose the housing is given a torpedo-form, the diameter diminishing towards the exhaust end where the form is continued by an end cap 4 provided with a blowing exit. The forward end of the housing is closed by a semi-spherical cap 3 with suction opening 10. The dust collector 11 protrudes into the forward hood, the rubber supporting ring 12 being provided with a carrier 13 enclosing the edge 14 of the dust collector.
