Carpet sweeper.
Patented in the German Empire on March 6, 1923.

The invention relates to a carpet sweeper, in which the rollers that the drive roller for the brush roller to rotate by friction, from on the box wall attached, resilient brackets bent circularly towards both ends.

There are these known roller carriers, however, not the rollers for good to friction with the brush rollers required pressure, and the effect is named deteriorated after wear of the rollers and brush rollers.

The invention consists in peculiarly designed, slidable on the outside of the Side wall held roller bracket the problems inherent in the earlier machines to eliminate. As a result, and that the pressure levers for the catch flaps in cutouts or bores in the wall are laid, any dirt will settle in the box prevented.

The subject of the invention is shown in the drawing, namely show:

Fig. Ι a rough outline of a view against a side wall, and

Fig. 2 and 3 show the push rod device for opening the flaps, which is installed in the box wall in two versions.

A steel wire hanger α is through a

Claw-like fastening block b is held outside in the middle of the box wall c and carries the rollers at its ends ei, d bent outwards at right angles. The long legs of the bracket are bent upwards to prevent the bracket from tipping over and to allow the largest possible, circular or similarly shaped bend at the ends downwards and towards the middle, which the latter ensures good lateral springiness for the roller friction and a This counteracts the spreading of the rollers when the pressure is applied to the box. The brackets designed in this way have a good spring force on all sides, which adapts better to the effect of the sweeper than with the previous brackets.

The bracket · β has its support point in the claw-like holder &, but shifts easily in the claw bore, so that it can be used even after heavy wear on the rollers, i.e. at their reduced diameter left or right ^ depending on the direction of travel of the sweeper, the driving role always gives a firm contact with the brush roller.

The push rods e for pressing down the flaps i are laid in milled holes or bores in the box wall c as shown in FIGS. 2 and 3. The shoulder f on the push rods e holds them up by means of a helical spring g and each rod holds the flap i, which is hinged to the lower end of the rod e with a pin h. By pressing the button or the button k on the rod, the flap is opened for the purpose of emptying dirt.

Claims (1)

Patent claim: Carpet sweeping machine with bow-like, resilient pivot support for the rollers, characterized in that each bow (a), which is attached to the outside of a longitudinal wall in a claw-like holder (b) and slidably mounted on the left and right of the claw, rises upwards from the claw, in one arc or one angled bend goes down, then approaches the middle of the box with its ends and finally is bent outwards at right angles to carry the rollers.
