Definitions
- the invention also relates to a brush cylinder, to the one end of which is attached an added auxiliary brush for the sweeping of sur ⁇ faces close to walls and similar obstacles.
- the object of the invention is to provide an improved solution to the problem of sweeping close to walls and similar obstacles. More speci ⁇ fically, an object is to eliminate the draw-backs and problems associ ⁇ ated with the known pencil-type side brushes. In particular, an object is to provide a light-weight brush which does not require heavy and/or complicated sweepers and transmissions, but which preferably may be mounted as an extension of the brush roller of existing sweepers.
- the invention is not limited, however, to mounting on cylindrical brushes, other types of drive are entirely conceivable for the brush according to the invention.
- the angle to the radial plane is greatest for the bristles at the outer ends of the first rows, the angle then diminishing along the rows, so that the bristles at the rear end of the rows, in other words next to the other end of the brush axle, coincide with a radial plane of the brush axle, or possibly lean slightly in the other direction, the brush row thus being shaped generally like a helical fan.
- all bristles in the first helical rows form an angle to the radial plane of the brush axle.
- second helical rows of bristles are preferably arranged between the first helical rows. It is then sufficient that said second rows extend helically from the second end of the brush axle a limited distance in along the brush axle, so as to fill the gaps behind the inner ends of the first rows.
- the angle of inclination of those bristles which extend past the one end of the brush axle is between 10 and 45° , preferably between 15 and 35°. It is possible also to let the bristles incline away from the ra- dial direction of the brush axle, so that the bristles lean forward in the intended direction of rotation.
- the number of first rows of brist ⁇ les should be at least three and at most six, suitably four, if also the said second rows are arranged between the first rows. Otherwise, the number of first rows is preferably doubled.
- the pitch of the heli- cal rows should be between 30 and 60° , preferably between 40 and 50°.
- the invention is not limited as to the choice of material for the bristle tufts, although stiff bristles of some synthetic material are preferred.
- Metal bristles and natural bristle material are also con ⁇ ceivable, however.
- the bristles used are stiff enough to reach into a corner by a wall and also to apply some pressure to the wall.
- the length of the brush axle and thus of the entire brush may vary, but normally the length of the brush axle is very much less than the overall diameter of the brush.
- the brush according to the invention thus cannot be compared to a conventional spiral brush. This may also be quantified thus: the distance that the inclined outer bristles or tufts extend past the said one end of the brush axle is at least 75 mm, preferably at least 90 mm, this being at least half the length of the brush axle.
- Fig. 1 shows a brush according to the invention in a side view
- Fig. 2 shows a sweeping apparatus with a brush cylinder, at one end fitted with a brush according to the invention.
- the brush according to the invention has been designated by reference numeral 1.
- the brush consists of a brush axle 2 with first and second bristle rows 3 and 4, respectively.
- the first and second bristle rows 3 and 4, respectively, are arranged alternately and both comprise four rows, the total number of bristle rows hence being eight.
- Both the first and the second bristle rows 3 and 4, respectively, are arranged in a helical fashion on the brush axle 2.
- the bristles in this embodiment arranged in tufts 5 and 7, respectively, incline in the first rows 3 away from the radial plane of the brush axle 2.
- the angle of inclination v is approximately 20°. This causes most of the bristle tufts 5 of the first bristle rows 3 to extend past the one end (the outer end) 6 of the brush axle 2.
- the bristle tufts 5 of at least the first bristle rows 3 in addition lean forward in the intended direction of rotation.
- the bristle tufts 7 of the second rows 4 do not incline towards the radial plane of the brush axle 2. They are, however, arranged heli ⁇ cally on the brush axle with the same pitch as the first bristle rows 3, and suitably also lean forward in the direction of sweeping in the same manner as the bristle tufts 5 of the bristle rows 3.
- the bristle tufts 7 of the second rows 4 cover the gap between the three rear tufts of the first rows and the radial plane coinciding with the se ⁇ cond (rear) end 8 of the brush axle 2.
- the brush axle 2 is provided with a screw 9 for mounting the brush 1 on a drive shaft.
- This drive shaft may be the brush axle of a cy ⁇ lindrical brush 10 of a sweeping apparatus 11, as indicated in Fig. 2.
- Fig. 2 also illustrates how the brush makes it possible to sweep close to a house wall.
- the manner of functioning of the brush 1 is that the bristle tufts 5 extending past the outer end 6 of the brush axle 2 feed the sweepings forwards and sideways away from the wall in the manner of a feed worm, the second bristle rows 4 then completing the feeding of the sweepings out toward the brush roller 10 of the sweeping apparatus 11.

Abstract
Brosse avec un axe rotatif. Autour de la périphérie de l'axe de la brosse (2), un certain nombre de soies raides ou de touffes (5) de soies sont disposées en premières rangées hélicoïdales (3), bien séparées les unes des autres, au moins les soies extérieures desdites premières rangées hélicoïdales, à proximité d'une extrémité (6) de l'axe de la brosse, s'étendant (s) au delà de ladite extrémité, de préférence parce qu'au moins ces soies des premières rangées hélicoïdales montées à proximité de ladite extrémité (6) de l'axe de la brosse forment un angle par rapport au plan radial de l'axe de la brosse, si bien que les soies s'étendant au delà de l'extrémité de l'axe peuvent atteindre des coins de parois et d'autres obstacles similaires, et au fur et à mesure que tourne la brosse, peuvent diriger les balayures vers l'avant et latéralement en les éloignant de l'obstacle. La présente invention a également trait à un balai cylindrique doté d'une brosse du type décrit, montée à l'une de ses extrémités.Brush with a rotary axis. Around the periphery of the axis of the brush (2), a certain number of stiff bristles or tufts (5) of bristles are arranged in first helical rows (3), well separated from each other, at least the bristles exterior of said first helical rows, near one end (6) of the axis of the brush, extending (s) beyond said end, preferably because at least these bristles of the first helical rows mounted at proximity of said end (6) of the axis of the brush form an angle relative to the radial plane of the axis of the brush, so that the bristles extending beyond the end of the axis can reach wall corners and other similar obstacles, and as the brush rotates, can direct the sweepings forward and laterally away from the obstacle. The present invention also relates to a cylindrical broom provided with a brush of the type described, mounted at one of its ends.
