Abstract

191,065. Bonelli, G. Dec. 29, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Teeth-cleaning appliances. - Apparatus for cleaning the teeth, mouth, or other parts of the body comprises clock-work driving- mechanism enclosed in a casing B, Fig. 11, provided with a catch A for winding and starting the mechanism. Mounted on the case is a tube X carrying at its outer end a tube H, Fig. 3, with one side cut away, in which are mounted longitudinally two cork-covered rollers 17, 18, driven by means of gears 14, 15, 16 from a shaft 11, which is actuated by a shaft passing through the tube X from the clockwork motor. The rollers 17, 18 rotate in bearings in two movable discs fitted into the tube H, and a wire 21, Fig. 4, folded so as to form projections at intervals is also mounted so as to rotate parallel to the rollers. A band of textile or other material pass-- ing over the rollers 17, 18 and the wire 21 is thus. caused to rotate on starting the motor. In the modification shown in Fig. 5, two rollers 32, 33 are disposed transversely in the tube J, which is cut away as before, the rollers 32 being driven through gearing 28, 29 from the shaft 26, and a. band of fabric runs over the rollers 32, 33.
