PROVISIONAL SPECIFICATION.
Improved Antiseptic Jute Dressings for Surgical Purposes.
JAMES FARMER ANDERSON, Manufacturer Airlie Works, Dundee, do hereby declare
the nature of this invention to be as follows:-
The application of Jute fibre to Surgical Dressings in improved forms.
The Jute is carefully selected, and rendered antiseptic by Perchloride of Mercury
Biniodide of Mercury, Carbolic Acid, or other antiseptic, applied either by steeping
in solution or permeating by vapour.
It is thereafter hackled by hand and machinery.
It is put up in convenient hanks of suitable size for one dressing, and in application
it is only necessary to undo twist, and one shake of hand lays it in exact form
required.
Some of these hanks, are thereafter put up in seperate paper packets and treated
with a composition of Alumn and Plaster of Paris &c. to render thein perfectly airtight
and fireproof.
They are then subjected to a high temperature of heat to render the fibre perfectly
sterile.
By the first process a finely absorbent antiseptic dressing is obtained ready for the
Surgeon's hand; and by the second, a dressing equally absorbent and perfectly sterile,
which can be kept for any length of time.

Improved Antiseptic Jute Dressings for Surgical Purposes.
JAMES FARMER ANDERSON Airlie Works Dundee Manufacturer 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 :-
The application of Jute fibre to surgical purposes in improved forms, viz.
The Jute is carefully selected, and rendered antiseptic by Perchloride of Mercury,
Biniodide of Mercury, Carbolic Acid or other antiseptic applied either by steeping in
solution or by permeating with vapour-preferably by steeping in solution.
The Jute is hackled or carded by hand or machinery.
It is then put up in convenient hanks or coils of suitable size for one dressing and in
application it is only necessary to undo twist, and one shake of hand lays fibre in
exact form required.
Some of these coils or hanks are put in airtight packets, and subjected to a high
temperature such as 150° C. for a considerable time say one hour and are thereby
rendered perfectly sterile.
In putting up for use (after being steeped in the antiseptic solution and dried) the
sliver or ribbon of Carded Jute which is then of from three to four inches broad, is
treated as follows.
(1) It is cut into lengths of 12 to 14 inches long.
(2) These lengths are each doubled in centre and twisted.
(3) They are thereafter packed firmly together by pressure in packets to suit
requirements.
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
(1) Convenience-That by this process and make up, a handy, convenient, antiseptic

page_text: dressing is obtained ready for the Surgeon's hand-cutting and breaking is avoided,
and a shake of the hand is all that is necessary to lay fibre in position.
(2) Economy Waste is entirely avoided one dressing or more can be detached
from bulk as required.
(3) Compactness-The make up admits of so much pressure being used in packing-
that the smallness of the parcel compared to the number of dressings useable, fits it
eminently for use either in Hospital or Field.
