Year: 1884

I WILLIAM ROBERT LAKE of the firm of Haseltine Lake & C° Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS RELATING TO THE PREPARATION OF
MATERIAL FOR SURGICAL DRESSINGS to be as follows:-
For the preparation of the dressing material referred to in the Specification of
my former Patent No 4444 AD 1883 to form a wadding suitable for various
surgical purposes I combine cotton-wool with wood fibre thereby retaining on, the
one hand the characteristic properties of the wood fibre that is to say its absorbent
quality, elasticity and cheapness whilst on the other hand, the size of the pieces of
wadding allows the bandages to be conveniently used for dressing.
According to my invention this wadding consisting of wood fibre and cotton
wool is manufactured by arranging over the outlet of an ordinary spreader a
quickly revolving carding roller which throws the wood fibre equally down upon
the cotton fleece as it passes along.
Instead of the carding-roller I may employ other apparatus such as a sieve or
other means for the equal distribution of the wood-fibre over the cotton.
The wood-fibre falling upon the cotton fleece is united with the latter by means
of a pressing roller arranged over the fleece cylinder and the wadding produced after
the several rotations of the fleece-cylinder is ready for use for surgical purposes.

I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, & Co, Patent
Agents, Southampton Buildings, in the County of Middlesex do hereby declare
the nature of my invention for "IMPROVEMENTS RELATING TO THE PREPARATION
OF MATERIAL FOR SURGICAL DRESSINGS" 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 the preparation of material for surgical dressings.
For the preparation of the dressing material referred to in the specification of
Letters Patent N° 4444 A.D. 1883 to form a wadding suitable for various surgical
purposes, I combine cotton-wool with wood-fibres thereby retaining, on the one 1
hand, the characteristic properties of the wood fibres, that is to say, their absorbent
quality, elasticity, and cheapness, whilst, on the other hand, the size of the pieces
of wadding allows the bandage to be conveniently used for dressing.
According to the present invention this wadding, consisting of wood fibre and
cotton wool, is manufactured by arranging over the outlet of an ordinary spreader 1
a quickly revolving carding-roller a, as shown in the drawing, which throws the
wood fibre equally down upon the cotton-fleece as it passes along.
Instead of the carding-roller I may employ other apparatus such as a sieve or
other means for the equal distribution of the wood-fibre over the cotton.
The wood-fibre falling upon the cotton-fleece is united with the latter by means
of a pressing-roller b arranged over the fleece-cylinder B, and the wadding produced
after several rotations of the fleece-cylinder is ready for use for surgical purposes.
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
The manufacture of a material for surgical dressings composed of wood-fibre
and cotton wool, by spreading the wood-fibre upon the cotton-fleece and uniting
the same by pressure.
