The present inventionrelates to a bristle for cleaning devices such as brooms, brushes, cleaning rollers, mats and the like, which are furnished with bristles and the cleaning .devices incorporating the bristles. In the case of brushes, Wire bristles are sometimes used instead of the piassava bristles which are mostly employed in such cleaning devices. However, wire bristles are liable to rust or corrode rapidly under the action of moisture and thus have only a limited life. Moreover such brushes can only be employed where the scouring action of the wire bristles is desired, or at least is not detrimental. Further, in the rollers of street sweeping appliances, bristles consisting of a steel wire enveloped in rubber have been provided. So far as the sweeping action of the rubber envelope and its 'reinforcement by the insertion of steel wire are concerned', such brushes have been .satisfactory but the steel wire is not suiliciently elastic even when made of very good material, i. e., is readily distorted, does not revert to its rectilinear form and is liable to break. Consequently such bristles also are not satisfactory for appliances in which 5 the bristles4 are subjected to large stresses such as occur more particularly in mechanically driven or rapidly moving appliances or those in which the direction of motion frequently changes.
' According to, the present invention a bristle which can withstand the most severe stresses is obtained by making its core of a high grade elastic wire rope and providing the core with a sheath of tough rubber or rubber-like material. A wire rope consisting of elastic wires such as high grade steel wires for instance, forming the core of the rubber sheath, has a high elasticity and thus a considerably greater life than a steel wire. To this extent the eect is similar to the effect of a wire rope as a driving belt in a comparison with a wire. In addition a bristle core consisting of singly or multiply cabled wires affords a better surface for the attachment of the rubber coating because the rubber or like material becomes firmly embedded in the helical grooves in the wire rope. The use of a wire rope also affords the advantage that even if individual wires break they remain associated with the remaining wires and do not emerge from the bristle.
Due to the number and fineness of the individual wires a varying elasticity of the bristles can be obtained in accordance with the purpose for which they are-to be utilized and in this way bristles of different elasticity can be associated with one appliance, in that for example the outside row or rows of bristles are stiffer so that these bristles effect the removal of coarse dirt or the like whereas the inner bristles which are more elastic, remove the finer dirt.
In the accompanying drawing:
Fig. 1 shows a bristle with an inserted wire,
y Fig. 2 shows a bristle with a singly cabled wire rope as the insertion,
Fig. 3 shows a bristle with a multiply cabled wire rope as the insertion, on a considerably enlarged scale.
Figs. 4 to 8 show examples of appliances equipped with such bristles,
Figs. 4 and 5 showing longitudinal and cross sections through a cleaning roller,
Figs. 6 and 'I side view and-bottom view of a broom,
Fig. 8 a cross section through a mat.
The bristle shown in Fig. 1 consists of a high grade steel wire a, e. g., a crucible cast steel wire, or a bundle of such wires, and a sheathing b of tough rubber or tough rubber-like material enclosing the wire insertion over its entire length. The rubber or like sheath is shown broken away from the core at the right hand and for the sake y of clarity.
` sweeping machine,
lshape through the apertures in In Fig. 2, the bristle consists of a rope or cable c of ilne wires of high grade steel constituting a. core and a sheath b of tough rubber or rubberlike material.
A particularly elastic bristle having a long life and therefore specially suited to the present purpose, is shown inFig. 3. This bristle has as core a wire rope c of high grade elastic wires enclosed in a surrounding cable c' also consisting of high grade elastic wires, the sheathing b of rubber or rubber-like material being applied to the outside of the core.
In general it is suiiicient for the individual wires of the wire rope to have a thickness of a fraction of a millimeter. 4
Figs. 4 and 5 show a cleaning roller for streetprovided with bristles according to Fig. 2 or Fig. 3. The body of the roller is shown by way of example as consisting of a tubular section d on peripheral elements e are secured so as to be spaced from the body in the radial direction; the peripheral elements are held together by lbolts f. Provided Yon the tubular body d are pins g to prevent axial displacement of the peripheral elements e. The two ends of the tubular body d are closed by discs h carrying the shaft As indicated in Fig. 5 the bristles are threaded in U- the peripheral Figs. 1 to 3 all being' which apertured sheet metal 'than thirty times that of a street sweeping roller provided with piassava bristles. The bristles do notbreaksothattherollercanbeuseduntil the bristles have been worn away to a very considerable extent without detriment to the sweeping action. Such a sweeping roller also enables the washing rollers which are otherwise customary for asphalt paving to be dispensed with because a street sweeping machine with bristles according to the invention can be used equally well for stone paving as for asphalt pavina'.
In the case of cleaning rollers provided with bristles arranged in lines, the outermost row or rows ofthe lines could for instance rbe stiller, i. e., provided with a core according to Fig. 1 for example, whereas the inner rows of the lines consist of the elastic bristles in accordance with Fig. 3 or Fig. 2.
Figs. 6 and 7 show a broom, particularly suitable for street sweeping purpos, provided with bristles in accordance with Fig. l and l'lg. 2 or Fig. 1 and Fig. 3 or Fig. 2 and Fig. 3. With such brooms lt is frequently desirable for the 4 bristles oi' the outer row or rows r to be stiffer than the bristles of the inner rows rl so that Fig. 8 shows a doormat provided with bristlesA in accordance with Figs. 1,2 or 3. In this case,
