  • Patent number: 5494187
    Abstract: A breadbox is usable as both a breadbox and a cutting board. The breadbox has a bottom portion (1), opposite side walls (2, 3), and a movable flap (5) which closes off a front opening of the breadbox. The flap has a cutting board surface and at least one shaft for pivotally coupling the flap (5) to the side walls so that the flap (5) is swivelable from a closed position where the flap closes the front opening of the breadbox (5) to an open position where the breadbox is open and the flap (5) is positioned substantially in a horizontal plane, such that the flap (5) has the cutting board surface exposed upwardly so as to be usable as the cutting board. The breadbox has a receptacle for crumbs which is disengageably attached to the front edge of the bottom of the breadbox.

  • Patent number: 4107809
    Abstract: A floor sweeper is provided. The sweeper includes a frame having a corner portion. A hub member is mounted at the corner portion for rotation about an upright axis which is inclined to the horizontal. The hub has a circumferential side face and an underside with faces toward a surface to be swept. An annulus of bristles projects from the sideface of the hub member. The bristles have free end portions projecting downwardly beyond the underside so that increments of the annulus consecutively contact the surface to be swept because of the inclination of the axis. An annulus of radially extending teeth are connected to the underside of the hub member from which they extend downwardly to thereby engage the surface to be swept so as to rotate the hub member.
