PROVISIONAL SPECIFICATION.
Improvements in the Construction of Brushes for Preparing Metals
for Electro-plating and for other like Cleansing Purposes.
We, WILLIAM ROCKLIFFE, Engineer of 8 Clarence Crescent, Whitley, in the
County of Northumberland, and ALFRED BEST, Model Maker, of Portobello
Lane, and ALEXANDER SUTHERLAND, Model Maker, of 90 Gladstone Street,
both in Sunderland, in the County of Durham, do hereby declare the nature of
this invention to be as follows :-
This invention relates to improvements in the construction of brushes for
preparing metals for electro-plating and for other like cleansing purposes.
To effect our purpose we propose to form the brush in parts so as to be able to
adjust its width or size to the required purpose by twisting or bending the wires
round a wire or other core of suitable form.
There may be as many of such brushes or parts of brushes thus formed as may
be required to form the necessary width of brush each part or core containing the
bristles being strung or threaded onto a common spindle or boss and secured by a
nut or washer threaded or plain as required or the wires forming the brush may be
doubled over to form a bight so as to form groups of bristles the bight ends
being capped or bound with solder or wire or other means for binding the ends
together.
Such ends may then be passed through perforations in a hollow boss or ring and
be secured therein by running in solder or other cement to bind all the capped
ends in position or the ends might be secured inside the hollow boss or ring by
threading or screwing therein clamping plates or washers to clamp the rings of
capped ends securely in position inside the boss or the boss may be constructed in
plates or laminations with radial grooves wherein the capped ends of the bristles
or groups of bristles may lie. Such plates may be threaded or screwed onto a
spindle one after the other so that the grooves therein may come opposite each
other to form holes for the capped or other inner ends of the groups of bristles.
The plates may thus be tightened up against each other to hold the groups of
bristles forming the brush or parts thereof a nut or the equivalent thereof serving
to lock the whole securely together.
The spindle or boss end may be furnished with an end brush for conveniently
dealing with corners or recesses in the metal or surface to be cleaned.

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 the construction of brushes for
preparing metals for electro-plating and for other like cleansing purposes.
To effect our purpose we propose to form the brush in parts so as to be able to
adjust its width or size to the required purpose by twisting or bending the wires
round a wire or other core of suitable form.
There may be as many of such brushes or parts of brushes thus formed as may
be required to form the necessary width of brush each part or core containing the
bristles being strung or threaded onto a common spindle or boss and secured by a
out or washer threaded or plain as required or the wires forming the brush may
be doubled over to form a bight so as to form groups of bristles the bight ends
being capped or bound with solder or wire or other means for binding the ends
together.
Such ends may then be passed through perforations in a hollow boss or ring and
be secured therein by running in solder or other cement to bind all the capped
ends in position or the ends might be secured inside the hollow boss or ring by
threading or screwing therein clamping plates or washers to clamp the rings of
capped ends securely in position inside the boss or the boss may be constructed in
plates or laminations with radial grooves wherein the capped ends of the bristles
or groups of bristles may lie. Such plates may be threaded or screwed onto a
spindle one after the other so that the grooves therein may come opposite each
other to form holes for the capped or other inner ends of the groups of bristles.
The plates may thus be tightened up against each other to hold the groups of
bristles forming the brush or parts thereof a nut or the equivalent thereof serving
to lock the whole securely together.
The spindle or boss end niay be furnished with an end brush for conveniently
dealing with corners or recesses in the metal or surface to be cleaned.
We will fully explain our improvements with reference to the accompanying
drawings in which Figures 1, 2 and 3 show respectively in each case an half
sectional elevational view and an half elevational view of different methods of
construction, Figure 4 showing in elevation a part in detail all as hereinafter
described and in the following description like marks of reference designate like.
parts.
Referring to Figure 1 of the drawings a is a spindle on which is screwed boss a¹
with flange a The brushes 2 are formed by twisting or bending the wires around
a wire ring 3 in the usual way so as to form ring-brushes.
The several ring-brushes 2 so formed are then threaded onto the boss a', a
clamping ring 4 being inserted between or against each separate brush formed as
above described and the whole is then tightened up by a nut or nuts N.
An end-brush 5 may be provided as shown for the purposes described.
In Figure 2 the spindle a, boss a' with flange a² are formed as above described
but the inner face of the flange a' as well as the faces of the clamping rings 4 and
the inner face of ring 4ª are formed with radial grooves 6 wherein the capped ends
of the bristles or groups of bristles may lie as shown very clearly in Figure 4
which is a side view of one clamping ring.
In this case the brush is not made as above described by bending the wires of
the brush round a ring-wire as a core and then threading the brushes onto the
spindle but separate groups of bristles are formed preferably by doubling the wires
to form a bight the bight-ends being capped or bound with solder or wire or other
suitable means. Such groups of bristles are then placed, one group in each
groove,, say of flange a (Fig. 2) and clamping plate 4 is either screwed or placed
in position as shown, the grooves in this plate being fitted against the groups of
bristles placed in position against a³.
The grooves in the plates are placed "off and on
the bristles over the area of the boss.

so as to properly distribute
When as many rings of groups of bristles as are required have been thus fitted

page_text: the nut N serves to clamp the whole securely together, an end-brush 5 being
fitted, if required, as shown.
By an alternative method of construction a hollow boss c may be formed as
shown in Figure 3. Separate groups of bristles formed as above described may in
this case be thrust through the perforations P in the boss as shown in the drawing
(Fig. 3) and clamping plates 4 may intervene between each ring of bristles, the
several rings of bristles and clamping plates being all made tight and secure by
the pressure of the nut N as clearly shown in this figure. The perforations will
alternate to distribute the groups of bristles evenly.
Instead of the clamping plates last mentioned the various inner ends of the
groups of bristles inside the hollow boss may be all secured by running in solder
to bind all the capped ends in position.
A brush so constructed can be readily taken to pieces to renew the bristles
when worn or when required.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :
1. The improvement in the construction of brushes for preparing metals for
electro-plating and for other like cleansing purposes consisting in the provision in
combination with the boss a¹ and flange a of the ring-brushes, clamping plates and
nut device all arranged, disposed and adapted for use substantially as herein set
forth with reference to Figure 1 of the drawings.
2. The improvement in the construction of brushes for preparing metals for
electro-plating and for other like cleansing purposes consisting in the provision in
combination with the boss a' and flange as having radial grooves therein of clamping
plates having similar radially-grooved opposite faces adapted to receive the inner
ends of separate groups of bristles and to be tightened up to secure the same the
several parts being arranged and adapted for use substantially as herein set forth
with reference to Figure 2 of the drawings.
3. The improvement in the construction of brushes for preparing metals for
electro-plating and for other like cleansing purposes consisting in the provision in
combination with a hollow perforated boss of groups of bristles secured therein by
clamping plates and nuts the several parts being arranged and adapted for use
substantially as herein set forth with reference to Figure 3 of the drawings.
4. The combination of parts forming the several improvements in the con-
struction of brushes for preparing metals for electro-plating and for other like
cleansing purposes substantially as herein described and illustrated.
