To all whom it may concern.-

. Be it known thatv I, WILHELM VON 'NIESSEN, captain lieutenant, retired, of the former Imperial German Navy-, citizen of Germany, residing at Wilmersdorf Berlin, i strasse, Prussia, Germany, haveinvented certain new and useful Improvements Bristles for Brooms andBrushes, (forwhich- Lhave filed applications in Germany, dated Oct: 1,1917, and [addition] N0v.22,;1917,) of which the'following is specification, reference being had therein to thefacc'ompany ing drawing. ,7

V The present--inventi'on*relates to a novel method of making the bristles for brooms and brushes from bamboo Madagascar, pep-,

per and similar reed. Heretofore such material was obtained from the reed or bamboo by shaving or splitting the same longitudijnally, and the bristles thus obtained were secured by means of pitch or the like into the brush-woodor broom-heads, because the use of wires for securing such bristles would easily cause the bristles to break at the point where they "have to be sharply bent over the wire." When the bristles are thus secured by means of pitch, they will not remain for long {tight in such position,-as the sharp edges ofthe bristles will, under the pressure in sweeping, soon destroy the pitch. The brush materialaccording to the of the customary means for, securing it in present invention, now, will not require any the broom head, becauseit has at one end an enlarged head, owing to the peculiar method ofcrosswise cutting the reed and subsequently splitting the same, as hereinafter described. This head will by itself securely hold the bristles in the broom head or brush-wood. Preferably the individual bristles are also split once or several times, also crosswise in a longitudinal direction from the free end up to close to the said head.

In the accompanying drawing- Figure 1 shows the way in which the reed or' bamboo pole is cutcrosswise and subdivided or split longitudinally.

thus obtained.

Fig. 3 is another bristle thus obtained,

split longitudinally on right angledlines and thereby forminga bundle of bristles.

' Fig. 5 is a cross-section through a bristle, which has been several times spllt longitudinally.

. Figs. 6, 7: and 8 show various modes of securing the bristles according to the'present invention.

As shown in Fig. "1, the reeds are cut crosswise, preferably by means .of a circular or'a band-saw, always on-the same side of the knots b and close to these (see out A..B). When the distance between two neighboring knots is very large the said cuts maybe made in such knots; and alsor'interme iary between them. After the reedshave been thus cut crosswise, they are split longitudinally to pieces having the form shown in Fig. 2. These pieces 0 have at the one end an enlarged head I). Of course it is also possible to first split the whole length of reed longitudinally into thin strips and then out these crosswise always on the same, side of the knots; but this would be much more troublesome and would neither yield the uniform pieces a. The closer the splits are made longitudinally, the thinner the said pieces 0 will be, which, when made from reed atented Sept. 13.1921. "Applic'atio'n lfild october 24,1919.- seria1-m.a3a,11s.

with thin walls, may be used as they are floors in factories or the like, the bristles must, however, be more elastic. T his is obtained by the pieces 0 being split again from their end opposite to the head, longitudinally but not throughout their whole length, and only to close up to the head. Such splitting of the pieces a may be done either once only, or several times on right angled lines, or the like, so that eventually the piece 0 consists of va-bundle of fine bristles joined together by the head 6. By such longitudinal splitting of the pieces 0 bristles of any degree of fineness may be produced. This splitting may be performed either by hand or by means of a special machine andis very easily carried out. As the core'part of the material will, after some time, break away here more easily allow of such splitting.

Besides a cut made closer to the core of the reed will always show the tendency to run toward the center, so that the individual bristles will becomeuneven and lead to unnecessary waste. a

-A'sthe knots are always closer to each other toward the root end, the short pieces of reed bristles obtained therefrom according tothe present invention may be used for making brushes, scrubbers and the like. The waste produced insplittingthe pieces 0 long'tudinally may be utilized as potbrushes'. 1

' The bristlesa produced according the present invention may be secured in various ways-into thebroomuheads or brush-woods.

This securing ofthe bristles does not fall within the scope of the present invention. It may be done, for example, in the manner shown vin Fig; 6, where the bristles are introduc'ed with their thin end through holes in the brush-Wood'fromabove; when the head 1) reaches thGbIUSh-WOOd d, it will be stoppedthere and a suitably recessed cover piece is placed'overthese heads. Or the bristle-holes may taper downward or be setofi (Figs. 7 "and 8) so as to receive the preventing the bristle-heads from shifting and eventually falling out from their holes, wooden shoe-pegs may be driven: into, the

art of the hole; 'The' empty spaces around them in said holes.
