Abstract: A kitchen or domestic food slicer having a flat bed surface over which the food is moved and a knife mounted essentially across that surface. The knife alone being pivotably mounted such that its sharp leading edge can be raised or lowered relative the bed surface to vary the thickness of cut. The pivoting of the knife is achieved by cam surfaces on a pair of bars one positioned either side of the bed surface, the bars being slidable lengthwise by a rotatable knob and the cam surfaces including inclined portions to cause pivoting of the knife as the bars slide longitudinally.

Abstract: A can opener providing a circular cut around the cylindrical wall of a can below the lid and rim which are severed by the cut from the rest of the can. A pair of body members having integrally formed handles are pivoted to one another. A rotatable spindle attached to a driving wheel drives the can opener. A cutting wheel forms a nip with the driving wheel in an operating position to force the cutting edge to penetrate through the wall of the can. A mounting plate carrying the cutting wheel is slidably supported by one body member and is movable by cam means between the operating position and a retracted position as the body members are pivoted between their limits of pivoting. In the retracted position the wheel withdraws into an upstanding guard whose edge abuts the severed top and displaces it.

Abstract: Floor-sweeping machine consisting of a housing with a revolving brush mounted rotatably therein and having pinions which are provided at its two ends and which are themselves each connected operatively by engagement to a pair of running drive wheels, the two running drive wheels belonging to a particular pinion being mounted rotatably in a wheel case and the wheel cases being mounted in appropriate housing receptacles so as to be vertically displaceable for adjusting the height of the revolving brush mounted fixedly in the housing, wherein, for a permanent adjustment of the height of the revolving brush without impairing the drive of the revolving brush by the running wheels, each wheel case (26) is retained by means of a wheel-case holder (38) to swing on one leg (44) of a U-shaped adjusting shackle (45), and the U-shaped adjusting shackle (45) is mounted pivotably in appropriate bearings (55) of the housing (11) by means of angled portions (54), shaped on the free ends of the legs (44), and an adjustable we

Abstract: A floor-sweeping machine consisting of a housing with a revolving brush which is mounted rotatably therein and is driven by means of running wheels and which is located between two dirt-collecting spaces, the two dirt-collecting spaces being formed by dirt-collecting containers which can be taken out of the housing upwards, and the dirt-collecting container having a resilient locking device which secures it in its operating position and which can be transferred by hand into its release position, and in which, to make it substantially easier to operate and especially to take out and empty the dirt-collecting containers, the two dirt-collecting containers 24, 25 are connected to one another and have a common top side 27 in which, approximately centrally, there is a part 35 which is to be grasped by the operator and is to be moved to a limited extent in the lifting-out direction and which, when moved in the lifting-out direction, transfers the resilient locking device 36 into the release position.

Abstract: Floor-sweeping machine consisting of a housing with a revolving brush which is mounted rotatably therein and which can be driven by means of running wheels projecting from the under side of the housing, and in which, for the purpose of rapid assembly and removal, the revolving brush 14 is mounted rotatably by means of two bearing clasps 19 which engage on its ends and which each have a bearing receptacle 24 for the associated bearing end of the revolving brush 14, and the bearing clasps 19 are themselves retained by securely positioned clamping onto housing parts 23.
