Filed: 1947-11-24
Abstract: 647,788. Reverse-gearing. KADT, M. DE, and KADT, J. DE. Nov. 24, 1947, No. 31131. Convention date. Jan. 13. [Class 80(ii)] [Also in Group XXIII] In a carpet sweeper (see Group XXIII) in which a rotary' brush 51, Fig 4, is driven uni-directionally from traction wheels 26, 27, each traction wheel has a rim 39, Fig. 9, and a central hub 38. A tyre 40 is provided around the outside of the rim 39 while the inside of the rim and the outside of the hub 38 are provided with a rubber lining 41 and a rubber covering 42, respectively. The lining 41 or the covering 42 is frictionally engageable, according to the direction of movement of the sweeper, with a knurled surface of a brush drive bushing 54, fixed on the end of a brush holder 47. The end of the brush spindle is retained in a slot 49, by a member 53 fitting in a groove 52 in the head 48 of the brush holder. Movement of the sweeper in the forward direction causes a cranked axle 30, Fig. 6, to pivot in a guide 31 in a counter-clockwise direction thus causing the lining 41 to ergage the bush 54 and so drive the brush 51. When the sweeper is moved in the opposite direction, the axle 30 pivots in a clockwise direction and thus causes the covering 42 to engage the bush 54 and thus continue to drive the brush 51 in the same direction as before.
