PROVISIONAL SPECIFICATION.
Improvements in Brushes for Pasting Cop-bottoms.
CHARLES BUTTERWORTH 47 Saint Thomas Street (North) Oldham Mill
Manager do hereby declare the nature of this invention to be as follows :-
In the process of spinning cotton or other such like fibre in a self-acting mule, to
which my invention more particularly refers, it is often a practice to paste the first few
layers of thread on the spindles in order to prevent the closing up of the hole in the
cop after withdrawal from the spindle.
Such pasting being effected by a brush secured in a metal box having two
divisions one for the brush and the other for the pasting material.
The brush is usually made up of two rows of bristles drawn through two rows of
holes in a wooden stock a brush so constructed speedily becomes hard, stiff, and
unworkable through a felting up of the bristles, in other words the space between
the two rows of bristles gets filled up with stiffened paste and waste fibre, the
inaccessibility of this rendering it difficult to clean thoroughly or easily.
My improvement consists in dividing this brash longitudinally in such a manner
as each half of the stock shall have but one row of bristles in it, and such parts
secured by hinges, dowels or other convenient methods, shall when put together,
appear and act as one brush, the only difference being that when dirty, they are
easily separated, and in such a separated condition are cleaned with the utmost
ease and despatch.
In order to prevent any tendency to warp 1 also make the divided stock of metal
instead of wood.

Manager 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 :-
In the process of cotton spinning the pasting of the cop bottom is an act
described as follows, and has for its purpose the hardening, of the layers of yarn
forming the bottom of the cop.
After a certain number of layers of yarn have been spun and wound on the
bare spindle the mule is stopped or caused to move but slowly and at the same
time an attendant applies by means of a brush a paste of starch or such like
material to the layers then on the spindle.
In order to expeditiously paste a large number of cop bottoms in rapid succession
the brush has been formed into a shape most satisfactory to its requirements
and is long and narrow having but two rows of bristles placed side by side in
a stock of wood, this brush is laid on its back into one of two compartments
formed longitudinally in a metal box, the other compartment containing the
pasting material.
The attendant in using the pasting box holds it in a horizontal position so
that the compartment containing the pasting material shall be uppermost and
that which contains the brush partly underneath, by tilting the box he is thus
enabled to cause the paste to flow into the bristles over or through the partition

page_text: in the box, and so by the bristles is distributed on to the layers of yarn composing
the cop bottom.
During use this common brush speedily becomes filled between the bristles with
a mass composed of stiffened paste and fibre. This felting up destroys the elasticity
of the brush and renders frequent washing a necessity. The portion of the mass
between the two rows of bristles is extremely difficult to remove.
My improvement in this brush consists in dividing it longitudinally in such a
manner that cach half shall contain but one row of bristles,the brush shall there-
fore be composed of two distinct portions secured or fastened together by hinges,
dowels, or other convenient methods, this division having for its effect the more
ready cleaning when dirty.
The method of use is as follows, when a divided brush becomes hard unyielding
and unfit for work through the felting up of its bristles, it is taken from the paste
box separated, and in this separated condition each half is easily cleaned.
In order to prevent any tendency to warp I also make the stock of the brushes
of metal instead of wood.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
(1) The division of a brush technically known as a pasting brush for cop
bottoms.
(2) The division longitudinally between the two rows of bristles for the more
ready cleaning thereof."
(3) The securing of each half so divided by dowels, pegs or hinges.
(4) The making of the stock so divided of metal or such like material.
