Improvements in the Manufacture of Surgical and Medical
Dressings.
We, WILLIAM BRADBURY ROBINSON of Field House, Chatsworth Road, CHARLES:
PORTLAND ROBINSON of Goldwell House, Ashgate Road, and WILLIAM BRADBURY
ROBINSON Junior, of Elm Lodge, Storrs Lane, all in Chesterfield in the County of:
Derby, Cotton Wool and Lint Manufacturers, do hereby declare the nature of this
invention to be as follows:-
According to this invention we produce a material for surgical and medical dressings.
by intimately mixing absorbent cotton wool and cellulose wadding.
We place a roll of fine cellulose wadding web of any desired thickness on or beneath
the web of absorbent cotton, as it is taken from the carding engine and the combined
web is then passed between rollers for its consolidation.
Absorbent cotton wool is known to be the most absorbent of surgical dressings but.
under pressure only admits of limited diffusion.
Cellulose wadding is after absorbent cotton, the most absorbent dressing & also.
permits of thorough diffusion by water or blood, but when cellulose wadding is.
saturated it loses its cohesiveness and elasticity and becomes so rotten that it has to be
picked off the part bit by bit which is a great objection.
We, by our method as described above, by combining the two, get a dressing with
the greatest absorbing power together with the greatest facility for the diffusion of
fluids and of perfect consistency.
It will be found that this dressing retains the soft and elastic properties of absorbent.
cotton either dry, wet or re-dried.

We, WILLIAM BRADBURY ROBINSON, of Field House, Chatsworth Road, CHARLES
PORTLAND ROBINSON, of Goldwell House, Ashgate Road, and WILLIAM BRADBURY
ROBINSON Junior, of Elm Lodge, Storrs Lane, all in Chesterfield, in the County of
Derby, Cotton Wool and Lint Manufacturers, 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:-
According to this invention we produce a material for surgical and medical dressings.
by intimately mixing absorbent cotton wool and cellulose wadding.

page_text: We place a roll of fine cellulose wadding web of any desired thickness on or
beneath the web of absorbent cotton, as it is taken from the carding engine, and the
combined web may then be passed between rollers for its consolidation, or if desired,
made up in a loose form either in rolls or in square sheets.
Absorbent cotton wool is known to be the most absorbent of surgical dressings but
under pressure only admits of limited diffusion.
Cellulose wadding is, after absorbent cotton, the most absorbent dressing and also
permits of thorough diffusion by water or blood, but when cellulose wadding is
saturated it loses its cohesiveness and elasticity and becomes so rotten that it has to
be picked off the part bit by bit which is a great objection.
We, by our method as described above; by combining the two, get a dressing with
the greatest absorbing power together with the greatest facility for the diffusion of
fluids and of perfect consistency.
It will be found that this dressing retains the soft and elastic properties of absorbent
-cotton either dry, wet or re-dried.
We proceed as follows:-
The absorbent cotton is carded on an ordinary carding engine and as the sliver
passes from the doffing comb to a Tumer drum, a Blamire feeder, or other machine, to
be made into a lap or roll, we place one or more slivers of cellulose wadding, which
unwind from previously made rolls on to the cotton sliver.
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. Surgical and medical dressings, consisting of a combination of cotton wool, and
-cellulose wadding, substantially as described.
2. The manufacture of surgical and medical dressings, substantially as described.
