583,738. Carpet sweepers. OYSTON, W. R., and NOVOBAX, Ltd. Nov. 24, 1944, No. 23453. [Class 138 (i)] The brushes 3 of a carpet sweeper, which is constructed without side rollers, are driven by means of a single broad cylindrical roller 8 located mostly inside the sweeper body 1, and the shaft 2 of the brush is mounted in the casing 1 by means of trunnions 1a, and is driven from the roller 8 by means of epicyclic gearing comprising rollers 9 engaging an inner sleeve 7 of the roller 8 and a driven sleeve 5 connected by a flexible coupling to the shaft 2. The coupling comprises a U-shaped member 6, Fig. 6, of flexible material preferably rubber. The rollers 9 are rotatably mounted in side plates 10 located alongside of side plates 11 supported by bearings 12 on shaft 2, the plates 11 being integral with the base plate 13 of a handle socket 13<1>. Slots 10a in the plates 10 permit a floating movement to the plates 11 and the roller 8 and epicyclic gearing. The brushes rotate oppositely to the roller 8 and when roller 8 moves forwards the brushes rotate clockwise and dust is directed by an apron 15 over the brushes into the pan 17. On backward motion of the sweeper the dust passes directly to the pan 17. The casing 1 is fitted with a comb 21 with triangular tongues 22, and the lid of the casing is held closed by a slot 23 in the lid and a loop 24<1> on the back of the casing, and a strut 24 with a bent-over end 24<x> may engage an aperture 25<1> in a heel piece attached to the base plate 13 to hold the handle 14 vertical when the apparatus is out of use.
