Dust sweeping device. Patented in the German Empire on December 6, 1925.

The object of the invention is a dust sweeping device for floors, mainly for floors of gyms, halls and the like.
It essentially consists of one

rectangular frame with three brushes spaced apart from each other on the underside are, namely a coarse brush, a soft hair broom and a so-called buff. The frame is preferred

pulled across the floor by hand. Of course there can also be a corresponding machine device can be used. With the new device, three operations are carried out in a single operation executed. The coarse broom mainly loosens the dust, the softer broom essentially sweeps it up, ίο while the cotton broom picks up the dust particles. With this arrangement of the various brushes, the new device is not how older similar dust sweepers designed to be pulled back and forth when sweeping to become. Rather, it is only pushed across the floor in one direction. Despite this one-time movement, the new sweeping device already has a ao thorough removal of the dust achieved. This speeds up the work of sweeping and relieved. Essential for the new device is the fact that the frame rests directly on the bristles of the three brushes without any other support, so that they wear out continuously, therefore always attack the ground evenly and can thus be used to the end. In use, with manual operation, a fork-like stalk is used that is fastened swingably at the center of the frame and can be tipped over by which the frame so that it can be carried away on the · floor means attached to one side of the frame rolls. An exemplary embodiment of the invention is shown in the drawing. Show it: Fig. Ι a view from above, Fig. 2 a side view, Fig. 3 is a view from below against the brushes, Fig. 4 the fork-like holder for manual operation and Fig. S the device ready to drive away. The frame of the device consists of the rectangular frame a, to which a bar b is attached by wing screws b ¹ for pressing the Schwabbeis e. On one side of the frame α small rollers c are attached, while in the middle of the frame angle plates d with holes J ¹ for inserting the pins f ^{1 of} the fork-shaped holder f are screwed for manual operation. A coarse brush g is attached to one side of the frame α , as well as an inclined, softer brush h and a cotton broom or buff e. The fork-shaped holder f consists of two parts / ² , the two stems of which can be pushed and clamped into the tube f ³ , which is provided with a handle ^{f 4.} The two parts / ² are first inserted into the holes d ^{1 of} the two angle pieces d and then connected to one another by the pipe f ^s. The brushes g and h and the buff e can be rotated and attached again with their ends on the opposite sides of the frame α. The buff e is coated with a dust-binding agent, e.g. B. water or a suitable oil soaked so that it can absorb the dust better. In use, after inserting the handle f, the device is pushed along the floor with the coarse brush g first. Appropriately, two or three such devices are pushed next to one another in a stepped manner over the floor to be cleaned. The two brushes g and h loosen the dust and collect it, while the buff e picks up the dust particles from the floor. Testing has shown that the cleaning by the device is a very is effective. Also, moving the machine forward across the floor requires so little force that even children can do it can be made. go PA T Ii NTANS V RUC H: Dust sweeping device with several parallel or almost parallel working devices, characterized by three devices (g, h, e), of which the first is a coarse brush, the second a finer brush and the third is a cotton broom soaked with dust-binding agent. 1 sheet of drawings.
