Application led August 20, 1920. Serial' No. 404,873.
are held by a plate or the like adapted'to be mounted on a rotary shaft, and the 0bject of the invention is' to provide simple and improved means for fastenlng the bristles or wires in place, said means 'consisting particularly of tongues struck up from the body of the sheet metal plate or disk on which the wires are mounted, the tongues serving to clamp the rings against opposite sides of the mass of bristles mounted on the plate. The construction 1s Such that the parts can be cheaply constructed, and the bristles can be easily renewed when desired.
' One form of the invention is illustrated in the accompanying vdrawings 1n which Figure l is a plan of thebrush. Fig. 2 is a detail in perspective of part of the middle disk or plate. Fig. 3 is a partial section of the brush.
Referring specifically to the drawings, 6 indicates a sheet metal plate or disk having a central hole 7 to receive a shaft on which it ma be mounted. Near its outer edge this dlsk is provided with a series of slots ,8, the number of which may be varied as desired, and which extend in a circular line around the edge of the disk. Wires 9 or other brush materials are inserted through these slots and then`-folded over outwardly to present their ends as the working surface of the brush.
- The bristles, wires or other materials are clamped in position on the disk by means of two flat metal rings 10 located respectively at opposite sides of the plate and lying against the opposite sides of the brush material. These rings are lheld in place by means of tongues 11- which are struck up from the body of the disk 6 on opposite sides thereof alternately and then bent over outwardly against the outer sides of the rings l0. i
T he brush material is thereby clamped agalnst opposite sides ofthe middle disk, and the rings 10 are preferably locatedso as to cover the bends orfolds of the bristles or wlres where they pass through the slots 8.
No fastemng is necessary other than the tongues 1l and the parts of the brush can be.
quickly assembled by inserting the bristles or wires and bending them as shown, and
, then slipping the rings in place and bending and pressing the tongues down upon the rlngs.' -To renew the bristles or lwires it is only necessary to bend the' tongues back and slip the rings off, insert new bristles or wires and replace the parts. The Whole brush is therefore mounted on a single disk or'plate, and it is unnecessary to mount the bristles or wires on al separate ring before being placed on the disk, as has beenproposed i n former constructions.
I clalm: p l. A rotary brush comprising a plate 'having slots around the outer edge thereof, b rush material inserted through said slots, rings .placed against opposite sides of said material, and tongues struck -up from the plate and folded over upon the rings.
