  • Patent number: 4180229
    Abstract: A kitchen appliance, such as a meat grinder, is equipped with a suction plate arranged underneath the bottom of the housing of the appliance. The suction plate is attached to the housing by means of a shaft which is mounted on the lateral walls of the housing of the appliance and can be withdrawn to thereby detach the suction plate from the housing of the appliance. The suction plate has an aperture in a connecting element thereof, and the shaft has an eccentric crank portion which is received in the aperture and lifts it upwardly, together with the central region of the suction plate, when the shaft is pivoted from a rest position to an extended position. When the shaft is pivoted further beyond the extended position, it reaches a releasing position in which the shaft can be withdrawn to dissociate the suction plate from the housing. A bulge on the connecting element, located beyond a dead-center position of the shaft, holds the shaft in its extended position.

  • Patent number: 4094032
    Abstract: A cleaning device includes a cylindrical brush which is mounted in a housing for rotation about an axis transverse to the direction of movement of the cleaning device over the surface to be cleaned. The brush has at least two sections which are independently driven into rotation about their axis by wheels which are also mounted in the housing. Motion is transmitted between the wheels and the two sections of the brush so that, when wheels on one side of the housing rotate at a different speed than the wheels on the other side of the housing, the rotations of the two sections of the brush about the axis are also different. A connecting element connects the two end portions of the sections of the brush which are adjacent to one another. Such connecting element may be connected to one of the sections of the brush for shared rotation therewith, or may connect the respective end portions with freedom of rotation relative thereto.

  • Patent number: 4040138
    Abstract: A drive for rotating a corner-sweeping brush of a sweeping device includes a gear on the brush, and a translation member provided with teeth engaging the gear and rotating the same about its axis with attendant rotation of the brush when the housing of the sweeping device comes into contact with an obstruction during its forward movement. An actuating member is connected to the translation member under interposition of a time-delay unit, and moves the translation member into engagement with the gear and subsequently toward an extended position thereof with concomitant rotation of the brush so that dirt is removed from the corner region of the surface being swept, even after the housing of the sweeping device has come to a standstill. The actuating member may be connected to a handle of the sweeping device, or it may be a discrete element projecting forwardly or upwardly out of the housing.

  • Patent number: 4028765
    Abstract: A floor or carpet sweeper has a hollow housing provided on its lower side with a plurality of floor-engaging wheels. The bottom of the housing is closed by means of a cover plate which is pivoted on the housing about an axis perpendicular to the forward and backward direction of travel of the housing during sweeping. This cover plate is formed with a throughgoing hole and is provided with upwardly bent tabs on which a cylindrical brush is rotatably mounted, this brush extending through the hole in the plate. In addition the ends of the brush are engageable with the wheels when the cover plate is closed on the housing so that the brush is rotatably driven by these wheels. A magnet holds the cover plate in place on the bottom of the housing and engages against an inclined surface on this cover plate. This magnet can be moved along the inclined surfaces so as to vary the height setting of the brush.
