The improvements consist in treating textile fabrics, unmade or made up into
articles of clothing, furniture, and such like; or horse-hair, feathers, and other
matters used for upholstering, by steeping or saturating them in a solution of
Norway pitch or tar dissolved in benzine or other suitable dissolvent, and
rendering the articles so treated antiseptic and capable of neutralizing infectious
germs.
The improvements are performed by making a bath of the pitch and benzine,
and plunging the articles therein, and allowing them to remain until they have
become thoroughly saturated; they are then wrung out and the surplus benzine
evaporated, and are fit for use.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Herbert John Haddan in the Great Seal Patent Office on
the 29th October 1881.
HERBERT JOHN HADDAN, of the Firm of Herbert & Co., Solicitors of Patents,
of 67, Strand, in the City of Westminster, Civil Engineer.
"IMPROVEMENTS
IN THE MODE OF TREATING TEXTILE FABRICS AND MATERIALS FOR SANITARY
PURPOSES." A communication from abroad by Jules Tisselin, of Paris, in the
Republic of France, Dyer.
This Invention consists in treating textile fabrics unmade or made up into articles
of clothing, furniture, and such like, or horsehair, feathers, and other materials used
for upholstering, by impregnating them with tar, for instance, Stockholm tar, for
sanitary purposes. In order to cause the absorption of the tar by the said materials,
I dissolve tar in benzine or any other suitable solvent, and steep them in this
solution or bath for a time sufficient to impregnate the textile fibres. When the
said materials have been taken out of the bath, I subject them to the action of a
drying apparatus for evaporating the benzine or other solvent, after which they are
ready for use. Instead of tar, any other resinous or balsamic substance, for instance,
Tolu balsam, may be used. By this process tar can be stored up in articles of
common use, thereby causing them to give off the smell, of tar for a long time after-
wards.
The solution of tar being almost colourless, produces no stain, so that this
treatment alters but little or not at all the appearance and colour of the fabrics
immersed. This process is applicable to textile fabrics or articles of clothing, such
as vests, flannel-shirts, drawers, &c., not only when they are new, but after they
have been bleached or cleaned, so that the store of tar may be renewed after it has
been nearly exhausted by wear. The strength of the tar solution may be varied to
make the articles treated by it more or less antiseptic.
CLAIM.
The application of tar to textile material of any kind and in any shape, either in
their fibrous state or as tissues, unmade or made up into articles of clothing or
upholstery, by dipping the said materials in a solution of tar, substantially as and
for the purpose described.
In witness whereof, I, the said Herbert John Haddan, have hereunto set
my hand and seal, this Twenty ninth day of October, A.D. 1881.
