Improvements in or relating to Rotary Brushes and Polishers.
1, FRANK BARKLAM, of Reservoir Cottages, Harborne Lane, Selly Oak, near
Birmingham, Cycle Works Storekeeper, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in rotary brushes and polishers. whereby
I am enabled to readily insert fresh brushing or polishing material such as wires,
bristles, fibres, leather or the like when the same become worn, or when desired;
and also to vary the length or width of the brush or polisher so as to adapt it to
the requirements of the work in hand.
At present rotary brushes usually consist of a wooden cylindrical stock or hub
having a central bore for the axis or spindle and a series of radial perforations
for the wires, bristles, fibres or other brushing material used.
means
Now according to my invention, I build up the said stock or hub from a series
of discs having radial semicircular or other section grooves cut in their side
faces, these discs are clamped together by
of clamping bolts
passed through them, the grooves of adjacent discs being arranged opposite to one
another and forming in conjunction the radial holes or apertures for the reception
of the brushing or polishing material.
It is obvious that when the brushing or polishing material becomes worn the
same can readily be removed, on loosening the clamping bolts, and replaced by
fresh wires, bristles, fibres, leather or the like; also by removing discs, or adding
additional ones, the length or width of the brush or polisher can be varied to suit
the requirements of the work in hand.
In the case of wire brushes, the wires would be made up into bunches or bundles
to suit the size of the brush holes, said bunches or bundles being composed of a
number of wires cut double the length of the bunch and folded over on them-
selves, the folded ends of the wires being arranged at the insertion ends of the
bundles and lapped round with fine wire.
Bunches of fibres, bristles and the like would be made up in a similar manner
but dipped in glue or other adhesive substance before being bound at the ends.
The holes formed by the conjunction of the radial grooves in the discs would
preferably be of slightly increased diameter in the line of the join so as to avoid
nipping the bunches between the edges of the grooves when the discs are clamped
up. Said grooves are also preferably provided with small projecting spikes which
enter the brushes and assist in holding them securely in position.
The discs may be made of any suitable metal or material, and the shapes of
the radial grooves therein may be varied according as they are intended to receive
bunches of brush material, or polishing material such as leather and the like.

I, FRANK BARKLAM, of Reservoir Cottages, Harborne Lane, Selly Oak, near
Birmingham, Cycle Works Storekeeper, 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 rotary brushes and polishers, whereby
I am enabled to readily insert fresh brushing or polishing material such as wires,
bristles, fibres, leather or the like when the same becomes worn, or when desired,
and also to vary the length or width of the brush or polisher so as to adapt it to
the requirements of the work in hand.
At present rotary brushes usually consist of a wooden cylindrical stock or hub
having a central bore for the axis or spindle and a series of radial perforations
for the wires, bristles, fibres or other brushing material used.
Now according to my invention, I build up the said stock or hub from a series
of discs having radial semicircular or other section grooves cut in their side
faces. These discs are clamped together by means of clamping bolts
passed through them, the grooves of adjacent discs being arranged opposite to one
another and forming in conjunction the radial holes or apertures for the reception
of the brushing or polishing material.
It is obvious that when the brushing or polishing material becomes worn the
same can readily be removed by loosening the clamping bolts, and replaced by
fresh wires, bristles, fibres, leather or the like; also by removing discs or adding
additional ones, the length or width of the brush or polisher can be varied to suit
the requirements of the work in hand.
In the case of wire brushes, the wires would be made up into bunches or bundles
to suit the size of the brush holes, said bunches or bundles being composed of a
number of wires cut double the length of the bunch and folded over on them-
selves, the folded ends of the wires being arranged at the insertion ends of the
bundles, and the said bundles or bunches bound round with fine wire over that
portion which is clamped in the hub.
Bunches of fibres, bristles and the like would be made up in a similar manner
but dipped in glue or other adhesive substance before being bound at the ends,
Toe holes formed by the conjunction of the radial grooves in the dises would
preferably be of slightly increased diameter in the line of the join so as to avoid
nipping the bunches between the edges of the grooves when the discs are clamped
up. Said grooves are also preferably provided with small projecting spikes which
enter the bundles or bunches and assist in holding them securely in position.
The discs may be made of any suitable material such as malleable iron, aluminium,
celluloid, wood or the like and the shapes, sizes or number of the radial grooves
therein may be varied according as they are intended to receive bunches of brush-
ing or polishing material such as leather and the like.
The radial grooves on the side faces of the discs would be preferably slightly
bell-mouthed to prevent fraying of the brushing or polishing material against a
sharp edge.
In case the material to be used for polishing or brushing purposes is of such a
nature as would render the radial grooves in the side faces of the discs unnecessary,
then these said radial grooves may be omitted and the side faces of the disc left
plain, or they may be corrugated, or else roughened in any convenient manner,
such as smearing them with glue and sprinkling emery on the glue.
The outer discs have radial grooves on one side face only, the inner discs have

page_text: radial grooves on both side faces, such grooves being placed on one side midway
between those on the opposite side.
This hub or stock can be put to work by fixing it on a spindle, shaft or axle of
suitable size having a worm or thread on it, and furnished with two loose collars
and two nuts, one collar and one nut to be fixed on either side of the hub or
stock and screwed up (similar to the fixing of an ordinary emery wheel) or in any
other convenient manner.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The building up of the hub or stock with separate discs and the clamping
together of these discs in the manner herein described so as to form a complete hub
or stock.
2. The ability to vary the width or length of the brush or polisher by using a
greater or less number of discs, and a greater or less quantity of brushing or
polishing material so as to suit the character of the work to be brushed or polished.
3. The ability to use successive lots of brushing or polishing material in one lot
of discs when such brushing or polishing material becomes useless through wear,
or when from any cause it is found desirable to change the same.
