Abstract

237,639. Brook, F. B. Jan. 1, 1925. Vacuum cleaning-apparatus; bellows.-A portable foot-operated vacuum-cleaner comprises two coacting suction bellows one of which is under and actuated by the foot while the other is coupled to it, the dusty air being drawn into one bellows and transferred through the other to a dust collector. The fixed bellows boards shown are constituted by a base 1 mounted on runners 4 and an upright panel 2 carried by it. The movable boards 5, 6, are braced together at an angle and are hinged at the apex to a block fitting in the angle of the fixed boards 1, 2 and formed with valved passages. The bellows are strengthened by hoops or ribs 11, and the board 5 is fitted with a heel rest 12 and foot grips 13. Dusty air is drawn through the suction hose 14 into the upright bellows 10 on the stroke caused by the pressure of the foot, and at the same time air and dust from the bellows 9 are expelled through a pipe 21 into a dust bag 19; on the reverse stroke, the dusty air in the bellows 10 is transferred to the bellows 9.
