PROVISIONAL SPECIFICATION.
Improved Process for Manufacturing Materials for Absorbing
Perspiration.
1, JULIUS LUTJE, Medicinal Doctor of 244 Grosse Bergstrasse, Altona,
Germany, Physician, do hereby declare the nature of this invention to be as
follows:-
The present invention is relating to a process for manufacturing of soles which
absorb the perspiration of the feet; the purpose of these soles being to do away
with the noxious suppression of the foot-perspiration by the usual means such as
salicylic powder &c. and to enable a free development of perspiration, but to
abrogate the bad effect of the perspiration by absorbing and dissolving the same.
For this purpose an ordinary linen or cork sole is impregnated or coated with
water-glass, and after being dried, it is inserted into the boot.
When the perspiration breaks out, it dissolves the water-glass in the sole and
combines with the same. Consequently the perspiration cannot decompose, nor
cause an unpleasant smell, nor attack the skin of the feet.
Materials impregnated with water-glass may also be used for other perspiring
parts of the body, in which cases the decomposition of the perspiration is effectively
prevented by the addition of antiseptic materials.
Dated this 16th day of November 1893.

COMPLETE SPECIFICATION.
Improved Process for Manufacturing Materials for Absorbing
Perspiration.
1, JULIUS LÜTJE, Medicinal Doctor, of 244 Grosse Bergstrasse, Altona,
Germany, Physician, 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 present invention relates to a process for manufacturing materials, especially
soles, which absorb the perspiration, for the purpose of doing away with the detri-
mental suppression of the perspiration by the usual means of salicylic powder etcetera,
and for enabling the free secretion of the perspiration, neutralizing the bad effect of
the perspiration through the imbibition and dissolution of the same.
For the above purpose an ordinary linen or cork sole or a sole of felt or other
fabric is impregnated or coated with solution of water-glass and when dry, placed
into the boot. When the perspiration breaks out, it gradually dissolves the water-
glass in the sole, and combines with the same. The perspiration cannot therefore
decompose, or cause a bad smell, or affect the skin of the foot.
Materials treated with water-glass may also be applied to other parts of the
body which secrete perspiration, the decomposition of the latter being effectively
avoided by the addition of antiseptic matter.

page_text: 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 :
Process for manufacturing materials especially soles for absorbing perspiration
by impregnating or coating a sole of linen or other fabric with a solution of water-
glass, as and for the purpose set forth.
