of the Commissioners of Patents on the 8th June 1882.

IMPROVEMENTS IN BRUSHES.
A communication from abroad by the Eagle Metallic Brush Company, of the State
of Massachusetts, United States of America.
In the construction of wire brushes, it is common to first prepare a flexible sheet
of rubber or some similar material, and insert in it headed points or wires more or
less closely, these wires taking the place of the bristles of the ordinary brush, then
this rubber or backing is attached to a suitable handle.
The present Invention relates to the method of attaching the rubber, or other
pad, in which the wires are inserted, to the bandle. This method of fastening
I will proceed to describe, reference being had to the accompanying drawings, in
which Fig 1 is a plan showing one of the improved brushes complete. Fig 2 is a
cross section of the same taken on the line x x of Fig 1. Fig 3 is a plan showing
the metallic rim which serves to hold the wire-holding pad to the handle; and
Fig 4 is a section much enlarged, of a part of the holding rim and the pad, also
showing one of the holding pins or starts.
The brush back or handle A A¹ is made in the form shown in Figs. 1 and 2, and
may be shaped and ornamented in any desired style.
The wire holding pad B, Figs. 1, 2 and 4, is made of sheet rubber or any similar
material, and is laid flat upon the back or handle A¹ (see Fig 2) and is then
fastened by means of a metallic rim C.
The sectional form of this rim C is shown in Fig. 4, in which h indicates the
inner edge or member of the rim, which rests upon the rubber B, and assists in
holding it in place; while the outer edge or member H, being made to extend
Din 1

page_text: beyond the plane of the inner edge h (see Fig 2), rests upon the back or handle
which gives it a firm support.
I attach to the under side of this metallic rim C, at intervals, a number of
holding pins or starts K Figs. 2 and 4. These holding pins or starts are connected
to the rim C, by soldering or otherwise, so as to form an integral part of the
Bame.
The process of attaching the pad B to the back A¹ consists in, first, laying the
pad B flat upon the back A¹, then placing the rim C in position, so that its holding
pins or starts K shall pass through the rubber near the margin as shown in Figs. 2
and 4;
then the rim is firmly compressed into the back A' which action causes, the
pins K to penetrate the pad B and back A¹, so as to firmly attach the pad to the
back or handle.
The outer edge H of the rim C extends over the edge of the pad B, and rests
upon the back A¹, so as to give an elegant and finished appearance to the brush.
This feature I accomplish by forming the holding rim C in the shape shown in
section at Fig 4, that is: with its outer edge H extending below the point to
which its inner edge h extends. This form of the rim C, saves the expense of
forming a sinkage in the brush back A¹ for the reception of the pad B.
CLAIM:
In a metal-toothed brush the combination of the pin-holding pad B, the rim C 2
provided with an inner member h, outer member H, and starts K, with the handle
A A¹, substantially as described, and for the purpose set forth.
In witness whereof I the said Jasper Wetter have hereunto set my hand
and seal this eighth day of June A.D. 1882.
