Improvements in Brushes for Electroplaters, Metal Polishers, and
the like purposes.
We, JOHN EBORALL HARTLEY, and HERBERT EDWARD HARTLEY, both
of 13 Saint Paul's Square, in the City of Birmingham, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in brushes, such as are used by electro-
platers and others and has reference more particularly to what are generally known
as circular polishing brushes, but which may also apply to brushes other than
circular, and for other similar purposes.
At present these brushes consist of a central stock upon each side of which and
near to the periphery a deep groove is cut so that the periphery is virtually like the
rim of a pulley. In this rim are bored a number of holes which said holes are of
two diameters, that is, at their inner part, that which passes through the groove is
smaller than that which starts froin the periphery. These holes are further bored
with a slight inclination so that the outer ends of the bristles press centrally
towards each other. The bristles &c. are pulled in from the exterior and
secured in the groove by wires, the said grooves afterwards being filled up by molten
lead &c.
In its application to circular brushes our invention consists of a centre stock
which is preferably of wood, but which may be of metal or other suitable material.
The periphery of this stock is shaped to receive a ring to which is secured the
bristles wires or fibres, which constitute the brush proper. This ring may be made
of leather, india-rubber or metal, or other suitable material, and may be glued,
screwed, pegged, or otherwise secured upon the stock.
As an example we may make a centre or stock of wood and turn in its periphery
a broad flat groove. We further take a strip of leather or india-rubber of a length
equal to cover the circumference of the stock, or a long length may be dealt with
from which required lengths may be cut. The required holes are pierced in and
the bristles, fibres or wires are passed into the holes and secured on the rear side
by wire, or other suitable means. This strip is then secured upon the stock by
glue, or screws, rivets, or other means.
Such brushes when worn down may therefore have the strips readily removed
and refilled and replared, or if desired in some cases, when the bristles &c. are
worn they may be trimmed off and the surface be prepared for and used as an
emery bob or be covered with felt or other material without destroying the said
stock.

the like purposes.
We, JOHN ЕBORALL HARTLEY, and HERBERT EDWARD HARTLEY, both
of 13 Saint Paul's Square, in the City of Birmingham, Manufacturers, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in brushes, such as are used by metal
polishers and others and has reference more particularly to what are generally
known as circular polishing brushes, but which may also apply to brushes other than
circular, and for other similar purposes.
At present these brushes consist of a central stock, upon each side of which, and
near to the periphery, a deep groove is cut so that the periphery is virtually like
the rim of a pulley. This groove weakens the stock. In this rim are bored a
number of holes which said holes are of two diameters, that is, at their inner part,
that which passes through the groove is smaller than that which starts from the
periphery. These holes are further bored with a slight inclination so that the
outer ends of the bristles press centrally towards each other. The bristles &c. are
pulled in from the exterior and secured in the groove by wires, the said grooves
afterwards being filled up by molten lead &c., a process which is both tedious and
requiring skilled labour. In its application to circular brushes our invention consists
of a centre stock which is preferably of wood, but which may be of metal or other
suitable material. The periphery of this stock is shaped to receive a ring to which
is secured the bristles, wires, or fibres, which constitute the brush proper. This
ring may be made of leather, india-rubber, or metal or other suitable material, and
may be glued, screwed, pegged, or otherwise secured upon the stock.
In order to explain more clearly this our invention we have appended hereunto an
illustrative drawing upon which are figures and numbers of reference, similar
numbers referring throughout the several views to the same thing or part.
Fig. 1, is a side view and Fig. 2 a front view of the centre or stock of the
brush.
Fig. 3, shows the leather or other strip to which the bristles are attached.
Fig. 4, is a side view and Fig. 5 a sectional view on line A-B of the complete
brush.
groove 9.
We make a centre or stock 8 of wood and turn in its periphery a broad flat
We further take a strip 10 of leather or india-rubber or other suitable
material of a length equal to cover the circumference of the stock, or a long length
may be dealt with from which required lengths may be cut. The required holes
are pierced in this strip 10, and the bristles, fibres or wires 11, are passed into
these holes and secured on the rear side by wire, or other suitable means. This
strip is then secured upon the stock by glue, or screws, rivets, or other means;
preferably we employ a strip of metal 12 in which are screw holes. This strip is
then secured thereto by the screws 13 as seen in Fig. 5.
Such brushes when worn down may therefore have the strips 10, readily
removed, and refilled and replaced, or if desired, in some cases,--when the strip
is secured by glue or cement-when the bristles &c. are worn they may be
trimmed off and the exterior surface of the said strips 10 be prepared for and
used as an emery bob or be covered with felt or other material without destroying
the stock 8.
In applying this our invention to brushes other than circular it will be readily

page_text: seen that the strip 10 &c. is laid upon the variously shaped surfaces in a similar
manner to that of the circular.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
In brushes for electroplaters and the like purposes the construction and combina
tion with the stock 8 of the strip 10 having the bristles &c. attached thereto, all
substantially as set forth and shown.
