Improvements in or relating to Rag-engines employed in the
Manufacture of Paper.
WC, JOHN HARGREAVES of 66 Watery Lane, Engineer, and RICHARD COOPER
of 19 Marsh Terrace, Blacksmith, both of Darwen in the County of Lancaster, .
do hereby declare the nature of our said invention to be as follows:-
This invention refers to improvements in or relating to rag-engines employed in
the manufacture of paper and is designed to thoroughly open, draw-out, and flatten
the fibre without unnecessarily cutting the same to allow of the manufacture of
stronger and better paper, also for the purpose of producing an equal or a better
quality of paper from a lower quality of material than hitherto. This we effect by
providing a metallic dead-plate of any suitable or convenient section with means for
securing the same in position. The metallic dead-plate is provided with chambers.
or recesses to receive emery, corundum, and other like mineral or minerals to form.
a surface in lieu of the steel or metallic blades at present employed. If desired
the dead-plate may be partly provided with emery, corundum, and other like
mineral or minerals and partly with steel or other metallic blades in combination.
according to the nature of the fibre or material to be operated upon.
Dated the 20th April 1892.

COMPLETE SPECIFICATION.
Improvements in or relating to Rag-engines employed in the
Manufacture of Paper.
We, JOHN HARGREAVES of 66 Watery Lane, Engineer, and RICHARD Coorer
of 19 Marsh Terrace, Blacksmith both of Darwen in the County of Lancaster, do
hereby declare the nature of our said 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 refers to improvements in or relating to rag-engines employed in
the manufacture of paper and is designed to thoroughly open, draw-out, and flatten
the fibre without unnecessarily cutting the same to allow of the manufacture of
stronger and better paper, also for the purpose of producing an equal or a better
quality of paper from a lower quality of material than hitherto. This we effect by
providing a metallic dead-plate of any suitable or convenient section with means for
securing the same in position. The metallic dead-plate is provided with chambers.
or recesses to receive emery, corundum, and other like mineral or minerals to form
a surface in lieu of the steel or metallic blades at present employed. If desired the
dead-plate may be partly provided with emery, corundum, and other like mineral
or minerals and partly with steel or other metallic blades in combination according
to the nature of the fibre or material to be operated upon.
Fig. 1 is a sectional elevation of our invention through line A, B, in Fig. 2.
Fig. 2 is a plan of same.
Fig. 3 is a sectional elevation of our invention in combination with steel or
metallic blades, and Fig. 4 is a plan.
C is the beater shaft; D the beater, and E the dead-plate. The dead-plate Ę.
may be of the form or section shown or otherwise constructed of either iron, steel,.
brass, or other metallic materials. The chamber or recess in the dead-plate E is.

page_text: filled with emery, corundum, and other like mineral or minerals, such as, sulphur,
cement, flint, glass, vulcanite, and the like mixed together to form a bond to
construct a wearing surface sufficiently hard to allow of the substance or material
in the rag-engine being operated upon in a most satisfactory and efficient manner.
If desired the dead-plate E may be filled with the steel or other metallic blades H,
the spaces between the latter being filled with emery, corundum, and other like
minerals described above to form a bond.
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. In a rag-engine employed in the manufacture of paper the use of a metallic
dead-plate having a chamber or recess filled or provided with emery, corundum,
and other like mineral or minerals to form a bond, substantially as described and
for the purpose specified.
2. In a rag-engine employed in the manufacture of paper the combination of a
metallic dead-plate having a chamber or recess fitted or provided with emery,
corundum, and other like mineral or minerals to form a bond, and one or more steel
or other metallic blades, substantially as described.
