PROVISIONAL SPECIFICATION.
Improvement in Waterproofing Woollen or Cotton Cloth and other
Materials.
I, EDWARD STEPHENS, 28, High Street, Totnes, Devon, Outfitter, do hereby
declare the nature of this invention to be as follows:-
-
My invention relates to improvements in waterproofing woollen or cotton cloth,
and other materials. In carrying my invention into effect, the material is treated
with a mixture of paraffin- or bees-wax and vaseline in any suitable proportions
of which I may instance four parts of wax to one or two parts of vaseline, the
relative proportions being however varied according to the material under treat-
ment. The mixture may be applied to the material by any suitable means in
any suitable manner, and either in a molten state or after solution in benzoline,
ether or other suitable solvent.
In order to more intimately impregnate the material with the waterproofing
mixture, heat may be applied at any stage of the process and in any suitable or
convenient manner.
Improvement in Waterproofing Woollen or Cotton Cloth and other
Materials.
I, EDWARD STEPHENS, 28, High Street, Totnes, Devon, Outfitter, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
-
It consists of the application to the material to be waterproofed of a mixture of
paraffin-wax (or beeswax) and mineral oils of the heavier hydrocarbon series (such
as vaseline, or some similar petroleum product or more than one of these)
mixed in the proportions of two parts of the former to one of the latter or in such
proportions as may be rendered desirable by the different materials to be water-
proofed, the thicker the cloth, the larger the proportion of the former.
This waterproofing mixture may be applied either in a solid state by rubbing it
on the material, or in a molten state or dissolved in some such spirit as benzoline,
ether or methylated ether. The mixture when melted or dissolved may be applied
to the material to be waterproofed by means of a hand brush or by drawing the
CD 017

page_text: material through a bath of the melted or dissolved mixture. After being applied
to the material to be waterproofed, the waterproofing mixture is forced into the
material by passing the material through or round heated rollers or between
heated plates or simply by passing a hot iron over it. A solution of alum may
then be applied to the material if desired, but with most materials, this is
unnecessary.
As an example of the method of carrying out my invention, I may instance
the treatment of cloth for army clothing. The cloth is in this case brushed over
with a mixture of four parts paraffin wax, and one part of vaseline, and the mixture
then forced in by pressing a hot iron over the material. The quantity of mixture
employed is at the rate of from one to three ounces to each yard of cloth, having
a width of fifty four inches, the quantity being varied according to the thickness
of the cloth being treated.
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. The use for waterproofing woollen or cotton cloth and other materials of a
mixture of paraffin wax (or bees wax) and mineral oils of the heavier hydrocarbon
series (such as vaseline, or some similar petroleum product or more than one of
them) compounded in or in about the proportions mentioned and applied in or in
about the manners described in the above specification.
'
2. The application in a solid state of the mixture, which is, the subject matter
of the above Claim 1, and for the purposes mentioned.
3. The application in a molten state of the mixture which is the subject matter
of the above Claim 1, and for the purposes therein mentioned.
4. The application after solution in some such spirit as benzoline, ether, or
methylated ether, of the mixture which is the subject matter of the above Claim 1,
and for the purposes therein mentioned.
5. The application of a solution of alum after the use of the waterproofing
mixtures as mentioned in the above Claims, 1, 2, 3 and 4.
