PROVISIONAL SPECIFICATION.
Improvements in Machines or Appliances used in the Manufacture
of Paper.
I JOHN WHITHAM BRETHERICK of No. 115 Red Earth Road, Darwen in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to
be as follows:
:-
This invention relates to improved apparatus specially designed for cleaning and
keeping free from sediment the plates of revolving strainers of paper making
machines, and thereby to secure an uniform flow of pulp on to the wire, and also to
maintain an uniform speed with the paper machine so in a great measure avoiding
the making of irregular thicknesses of paper.
According to this my said invention I employ brushes which are formed in two
or more lengths for the convenience of being removed and replaced expeditiously
the wooden part or brush stock is set with hair or bristles preferably half way
round the same the said brushes extend the whole length of the strainer plates, and
are supported at their ends by metal arms or levers the latter at their other ends
being fixed to double joints screwed to the side of the strainer box whereby the
brushes are allowed to adapt themselves to the square revolving strainer, or any
other form used for the same purpose. To the centre of each brush is fixed a brass
loop or ring to which is attached a cord the latter being carried above the machine
and over a second pulley fixed in any convenient position, and to the free ends of
these cords are attached small weights for the purpose of counterbalancing the
brushes and reducing their friction on the strainer plates if desirable, and also
making the brushes adjustable to the strainer box.

COMPLETE SPECIFICATION.
Improvements in Machines or Appliances used in the Manufacture
of Paper.
I, JOHN WHITHAM BRETHERICK of No. 115 Red Earth Road, Darwen, in the
County of Lancaster, Engineer, 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 improved apparatus specially designed for cleaning, and
keeping free from sediment, the plates of revolving strainers of paper making
machines, and thereby to secure an uniform flow of pulp on to the wire, and also to
maintain an uniform speed with the paper machine so in a great measure avoiding
the making of paper of irregular thickness.
According to this my said invention I employ brushes which are formed in two,
or more lengths for the convenience of being removed, and replaced expeditiously.
The wooden part, or brush stock is set with hair, wire, or bristles preferably only
half way round the same the said brushes extend the whole length of the strainer
plates, and are supported at their ends by metal arms, or levers the latter at their
other ends being fixed to double joints screwed or otherwise fixed to the side of the
strainer box whereby the brushes are allowed to adapt themselves to the square
revolving strainer, or any other form used for the same purpose. To the centre of
each brush is fixed a brass loop, or ring to which is attached a cord, the latter

page_text: being carried above the machine, and over a guide pulley fixed in any convenient
position, and to the free ends of these cords are attached small weights for the
purpose of counterbalancing the brushes, and reducing their friction on the strainer
plates if desirable, and also making the brushes adjustable to the strainer box.
Such being the nature and object of my said invention the following is a complete
description of same reference being made to the accompanying drawings forming a
part of this Specification, in which :-
Fig. 1 is a plan view of my improved appliances connected with paper making
machinery.
Fig. 2 is a sectional end elevation of appliances aforesaid.
According to this my said invention I employ brushes 1. 2 which are formed in
two, or more lengths 1. 2 for the convenience of those who remove, and replace
same, and in order that this may be done expeditiously. The wooden part, or
brush stock 3 is set with hair, wire, or bristles 4 preferably only half way round,
or over such portion of same, as comes in working contact with the strainer
plates 5.
The brushes 1. 2 extend the whole length of the strainer plates 5, and are
supported at their ends by metal arms, or levers 6. 6 the latter arms, or levers 6. 6
at their other ends being mounted, or carried by double joints 7. 7 screwed, or
otherwise fixed to the side of the strainer box 8, and the brushes 1. 2 by turning
on their joints 7. 7 are allowed to adapt themselves to the square revolving
strainer 5, as shewn by the drawings, or to any other form of strainer used for the
same purpose. To the centre of each brush 1. 2 is fixed a brass loop or ring 9 to.
which is attached a cord 10 the latter being carried above the machine, and over a
guide pulley 11 fixed in any convenient position, and to the free ends of these cords
are attached small weights 12 for the purpose of counterbalancing the weight of the
brushes 1. 2 and their connections, and reducing the friction of the brushes 1. 2 on
the strainer plates 5 if desirable, and also making the brushes adjustable to the
strainer box, and allowing of their being turned back, or away, and clear from the
strainer box when required.
Having now particularly described, and ascertained the nature and object of my
said invention and in what manner the same is to be performed I declare that what
I claim is :--
In machines employed in the manufacture of paper:-A brush, or brushes so
mounted as by self acting adjustment to follow, and operate on the surfaces of
square, and other shaped strainers.
