Abstract: 1,038,584. Abrading. T. W. ANNIS. Jan. 29, 1965 [Jan. 30, 1964], No. 4142/65. Heading B3D. A machine for abrading floors and baseboards comprises a brush housing 4, Figs. 1 and 2, a brush drive shaft 6, and a brush member disposed at the lower end of the shaft, the brush member having a core portion 32 and a multiplicity of flag portions 44 of flexible abrasive material extending radially outwards from the core portion, the flag portions extending below and outwardly of the housing for abrading the baseboards and downwardly of the core for abrading the floor. The shaft 6 is formed with a flange 14 by which it is secured by fasteners 16 to an adapter 8 consisting of a shell 10 having a filler 18 of foamed plastic material adhered to a clutch pad 20. The brush member has an outer core portion 32 which may be of foamed plastic material and has on its upper and lower sides clutch pads 26, 34. The upper clutch pad 26 frictionally engages the clutch pad 20 and is secured to the upper element 29 of an inner core member non-rotatably received in the outer core portion and secured by a fastener to the lower element 31 of the inner core member which is secured to the lower clutch pad which, in use, acts to clean the floor. The flag elements are of abrasive material which may be fibrous material, such as nylon, and project beyond a rim 22 of the housing, which rim acts to locate the brush member, and below the pad 34. The elements are formed with radial slits 46. The flag elements may consist of single pieces adhered to the outer core portion 32 or consist of sheets doubled over and secured at the fold to the portion. In another embodiment, the elements are formed by a continuous strip folded into undulations about vertical fold lines, Fig. 5 (not shown), or horizontal fold lines, Fig. 6 (not shown). In a further embodiment, the continuous strip is coiled in the form of a helix about the core portion, Fig. 8 (not shown). In yet another embodiment, the elements 202 are formed from folded sheets 204, Fig. 12 (not shown), the inner portions having flaps 206 folded on to the sheets so that there are four thicknesses of material. Spacer elements 214, Fig. 13 (not shown), are placed between adjacent flag elements and the whole secured together by a strap 212 passing through slits 210 in the elements. The spacer elements 214 may have their upper ends frictionally engaging the adapter member 218, Fig. 11 (not shown), to provide a drive for the brush member. In another embodiment, the outer core portion 32 is mechanically locked to the adapter 8 by a non-circular sleeve 54, Fig. 10 (not shown). The flag elements 304, Fig. 14 (not shown) may be secured to a flexible and elastic loop 302 which is removably located between the flanges 308, 310 of a wooden core member 306. The lower surface of the member has a drive surface for frictionally engaging a floor pad 320. The member may be fabricated from metal and be formed with or without the flanges. In the embodiment illustrated in Fig. 9 (not shown), the flag elements 144 have parts 152 extending radially of the lower surface of the core 128 to abrade the floor. In another embodiment, the adaptor 402, Fig. 15 (not shown), comprises a shell 404 welded to a disc 406 having a pad 408 for frictionally driving a floor pad 409. A loop member 418 is disposed about the flange 416, is secured to brackets 422 welded to the flange, and has flag elements secured thereto. The flag elements may be disposed at an angle inclined to the axis of the brush.
