ROTARY BRUSH-f SPECIFICATION forming part of Letters Iatent No. 599,044, dated February 15, 1898.

Application filed September 3, 1857. Serial No. 650,530. (No model.)

brushes employed in certain industries, particularly in the manufacture of boots and shoes, for finishing, polishing, and other operations.

In order that myinvention and the manner in which it is to be performed may be clearly understood, I shall describe it with reference to the accompanying drawings, in which Figure l-is a cross-section of my improved rotary brush on the line 1 lof Fig. 2. Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1 of a brush constructed according to my invention; and Fig. 3 is adetail section, on a larger scale, of one of p the disks which compose my brush, showing the manner in which the bristle-tufts are fixed therein.

My brush consists of an iron tube A, fixed on the driving-shaft, which is intended to impart rotary motion to the brush. At one of its ends this tube is formed with a fixed head B, while at its other end it is screwthreaded toreceive a movable head 0, similar to the head B, and which is arranged to screw upon the screw-threaded portion of the tube. These heads serve to clamp between them the whole of the disks D, which form the brush. Each of these disks (which are all threaded onto the tube A and are held on the latter by the grip of the heads B and C) is preferably made of walnut wood,although any other suitable wood may be used. Upon one of its faces this disk is formed with a groove or circular recess E (best shown in section in Figs. 2 and 3) and in which there opens a certain number of equidistant notches F, formed in the same face of the disk-radially-to its circumference and extending only over a part of the thickness of the dis To mount the brush, I proceed in the following manner: After having unscrewed the movable head 0 from the tube I place upon the latter one of the disks D, which I push onthe tube until its full face bears against the fixed headB of the tube. Then, the tufts having been made of the desired length by folding the bristles to form a loop, I insert into the loop G of each tuft G thus formed.

, one of the legs of a metallic fastener or staple H of n shape. I then dip the tuft and the staple into hot pitch, and I insert the tuft thus dipped into oneof the notches F, nailing the stapleH onto the disk D and taking care that the pitch shall not get beyond the surface of the disk, so as not to form upon the latter an extra thickness, whichwould prevent the next following disk fromfitting close up. When all the notches in the disk D have been filled in this way, there is threaded head 0 is placed in position and-is tightened up as firmly as possible, and the brush is thus mounted. As the legs of the staple II are longer than the thickness of the disks, the result is that when the staples are driven in they pass through the disk in which they are inserted and they become fixed in the preceding disk, whereby a homogeneous whole is formed. After thedisks have been'thus piled together and tightened up together there is no longer any danger of the bristles leaving the brush, because they are held in the notches F by the staple passing through the loops and by the pitch.

It is to be understood that I do not limit myself strictly to the precise arrangement of the parts shown, because .it is obvious that the arrangement may be varied to a certain extent without departing from the principle of my invention.

I claim .1. A cylindrical brush composed of a number of disks each provided on one of its faces notch or groove radiating from each of said recesses to the periphery of the disk, brushtufts formed by doubling a bunch of bristles, the said tufts within the radial grooves and the doubled ends thereof Within said recesses, and staples attaching said doubled ends within their recesses and the disks together, substantially as described.

3. A cylindrical brush composed of a tubular hub screw-threaded at one end and pro vided with a circular head at the other, a number of disks each provided with radial notches or grooves in one of its faces, tufts
