BRISTLE-RIM FOR ROTARY BRUSHES.
placed around a wire, after which they are held in position by two disks or rings which are firmly pressed against the bristles, the whole forming a bristle rim. The rotary brush composed of such bristle rims presents the disadvantage, that the bristles can easily shift between the disks or rings, more particularly when the brush is long and is rotated at a great speed.
My invention relates to improvements in such bristle rims, and the ilnprow-mcnts consist in n'iaking thedisks or rings of sheet metal and in providing them with projections pressed out of their material, which projections engage in the bristles and thus take hold of them, whereby, even when the brush is rotating at a high speed, any loosening of the wire or binding ring, as well as any shifting of the bristles on the circumference of the disks or rings is effectually prevented. Then it will be possible to use the brush until the bristles project only a few millimeters beyond the holding disks or rings.-
I will now roeeed to describe my invention with re erence to the accompanying drawing, in which- Figure l is a side View of an improved bristle rim, a part of the bristles being fully shown, while the rest is indicated by a dotted circle, Fig. 2 is a cross section on an enlarged scale through the line A-B in Fig. 1, and Fig. 3 is a similar cross section through the line C-D in Fig. 1.
Similar characters of reference refer to similar parts throughout the several views.
The bristles 1 are bound together by means of two disks or rings 2 and 3 made from sheet metal and are held between the rings or disks by a cord, wire, or the like t in any known manner. The disks or rings 2 and 3 are each rovided with projections 5, 5 pressed out of their material. The pro- Spccification of Letters Patent.

jections 5, 5 on one disk extend in close proxin'nty to the other disk and engage between the bristles 1, as is clearly shown at lflgs. 2 and 3. The projections 5, 5 of either of the two disks 2 and 3 are made to alternate with those of the opposite disk, as can be seen from Fig. l, where one of the pI()]6Ct1QIlS 5 of the rear disk 3 (in the line C D) 1s indicated by dotted lines. The pro ections 5, 5 are shown to be square, but this shape isimmaterial and may be varied.
The two disks 2 and 3 of each bristle rim are to be connected with one another in the following manner: The inner periphery of one disk 2 is bent over in the direction in which the projections 5 project, so as to form a border 6. The inner periphery of the other disk 3 is so bent over as to form a 7, this flange being partially cylindrical or slightly conical. The bristles 1 are then in any known manner assembled on the ring or disk 2 and are bound together with a wire 4 or the like, after which the bristles are doubled by bending and spreading outward, whereupon the ring or disk 3 is placed on them and its flange 7 is pushed into the border 6 of the disk 2 and is bent over by means of a press or any known tool, so that the border 7 overlaps the mner periphery of the disk 2, as. is clearl shown at Figs. 2 and 3.
It epends upon the size and thickness of the dlsks 2 and 3, whether the projections 5, 5 are pressed out at the same time that the borders are bent or not. For larger disks of a not inconsiderable thickness it is of course preferable to perform these two operations simultaneousl while for smaller thin disks it is preferable to produce the projections only after the bristle rim is finished and this by means of a pair of suitable tongs or any other known tool.
The several bristle rims destined to form a rotary brush are to be juxtaposed 011 the outer face of some spindle, sleeve, or hub and there secured between flanges or the like in any known manner, so that the two disks 2, 3- of each rim engaging one another by their borders 6, 7 are adapted to press the bristles 1' together under the pressure of the flanges or the like.
The projections 5, 5 engaging between the bristles 1 prevent any shifting of the same between the two disks 2 and 3, so that the bristles 1 can not produce unequal displacements of the binding wire 4 around the rim as hitherto. The projections 5, 5 alternating with one another and extending from one disk in close proximity to the other disk permit it to reliably secure the bristles 1 with a relatively small number of projections on each disk or ring.
I claim:
In a bristle rim for rotary brushes, the combination with two annular disks made from sheet metal, bent over at the inner periphery so as to form borders which engage one another and having inward projections pressed out of the material of the disks, of bristles their inner doubled ends by means of a binding wire between said two disks, said two disks being adapted to hold the bristles together, while the inward projections of one disk extend in close proximity of the 20 other disk and alternate with the inward projections of the latter.
