BRUSH WHEEL.

No. 102,932; Patented May 10, 1870.

To dllwhonm't may concern:

' that of the arbor waited giant Letters Patent No, 102,932, dated May 10, 1870.

IMPROVED seven-wanes.

The Bohedrde referred to in these Letters Patent andmaking part of the same.

Be it known that I, PHILIP Fnmzsn, of-the city and county of P rovidejnccand State of Rhode Island,

have invented a new andnsful Brush-Wheel.

' My invention relates to that class of brushes in which the bristles are set in the edges of disks of wood, 31d which are generally employed for polishing metals,

It consists in forming in the body of the wheel, and upon each side near the eye, a groove, in such a manner as to leave recessed, shoulders around the eye, upon which'shoulders metallic sleeves are placed, fora purpose to be hereafter explained.

And I do herehy'declare the following to be a full, clear, and exact able others skilled in the art to which the invention. pertains to make and use the same, reference being had to the accompanying drawing forming part of this specification, and in whicha i Figure 1 is a side view of a brush-wheel constructed in. accordance with my invention, and

Figurc 2, a cross vertical section of the same.

Similar lettersof reference indicate corresponding parts in both figures. i

In the drawingsg 5 I y A represents thebody oi. the wheel.

B, in" each case, epresents groovcs'made in the body A, upon each side and near .the eyc.

a O is'the of the wheel, 'of 'a size corresponding with upon which the wheel is to be mounted. e

D, in each case, represents recessed formed around the-eye O by-the grooves B.

Instead of making grooves in the body of the wheel to form the shoulders for-the support of the sleeves, a projecting flange might be madearound the eye to serve a similar purpose. I prefer, however, the former plan, it being economical in material.

shoulders,

description thereof, suflicient to on- E, in each case, represents the metallic sleeve or sleeves, encircling and resting upon the shoulders D, after the manner of a wheel tire.

It will be. seen that by the employment of the sleeve or sleeves in the mannerI haveshown, the

warping and cracking of the wheel, which so often occasions great inconvenience, is prevented. In cases whc-reabrush-wheel is mounted upon an arbor, and nuts and washers are required to hold itin place, they being placed upon each side,'thc continuous pressure of these nuts and washers against the body of the wheel, often cause it to crack and become useless, sometimes whcn'the bristles are only slightly worn. d 1

By providing the bodyof thewheel with the sleeves they receiveall the strain, the pressure being against them when the wheel isiu position upon the arbor.

Ifthe wheel be mounted upon the cnd of an'arhor, provided with a screw-thrcad, fitting theeyc-O, as is generally the case, there is a constant outward strain liable to crack the wood, and render the brush-wheel worthless. v

A partially satisfactory result follows the use of a single sleeve, although, as the expense is trifling,l

prel'er both, as shown.

Having thus described nly invention, I claim as new and desire to secure Patent- The improved'wooden brusli-wheel herein described,

consisting of the body A, provided with the metallic sleeve or sleeves E, fitted to recessed or projecting shoulders on the face or faces-of" the wheel, substantially as shown and described PHILIP FELKER.
