PROVISIONAL SPECIFICATION.
Composition for Use in the Waterproofing of Woven Fabrics.
I, ERNEST JOHN KNOWLTON of 'North State Street, Ann Arbor, Washtenaw
County, Michigan, U.S.A., Manufacturer, do hereby declare the nature of this
invention to be as follows:-
The composition of this invention may be used generally in the processes for
waterproofing woven fabrics but is more especially designed for use with fabrics
employed in the construction of portable baths which fabrics may be of any cloth
equal in texture to good drilling or closely woven, fine, light ducking. The com-
position consists of linseed mucilage of about the consistency of thin starch used in
laundry work in a quart of which a quarter of a pound of Spanish white is mixed,
or in place of the Spanish white ochre, ground chalk, soapstone or pumice stone
may be employed. This composition is applied for the purpose of filling up the
pores of the fabric previous to the application of the waterproofing material.
Dated this 20th day of July 1894.

Composition for Use in the Waterproofing of Woven Fabrics.
.
I, ERNEST JOHN KNOWLTON of North State Street, Ann Arbor, Washtenaw
County, Michigan U.S.A., 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 composition of this invention may be used generally in the processes for
waterproofing woven fabrics but is more especially designed for use with fabrics
employed in the construction of portable baths which fabrics forming the sack or
body of the bath may be of any cloth equal in texture to closely woven, fine, light
ducking.
The composition consists of linseed mucilage of about the consistency of thin
starch used in laundry work in a quart of which a quarter of a pound of Spanish
white is mixed. To produce this flax seed mucilage or linseed mucilage as it is
termed I take two pounds of common flax seed and cook it in about half a gallon
of water until it reaches the consistency of common laundry starch. If the
mucilage should be found to be too thick more water and if too thin more seed may
be added. When cooked the seeds are strained out, the Spanish white mixed in
and the liquid used in the manner of ordinary starch to size the sack or body of
the bath which for this purpose is placed in a frame. After the bath body has
been thus sized it is thoroughly dried and then coated with a waterproofing material
preferably with a composition comprising half a gallon of raw linseed oil thickened
by dissolving therein by the application of heat a quarter of a pound of beeswax
and half a pint of driers. Two or three coats of this composition are applied to
each bath body and each coat sand papered after being seasoned for a week or
ten days.

page_text: The use of flax seed mucilage and Spanish white for filling the pores of the
cloth in place of the common paste and other stock hitherto used is designed for
the better prevention of drying out or cracking.
In lieu of the Spanish white or whiting which is used to thicken the mucilage,
ochre, ground chalk, soapstone or pumice stone may be employed.
The proportions given may of course be varied according to the judgement and
experience of the workman and to suit different textures of cloth and difference of
the temperature in which the sack or bath body is cured.
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 :-
A filling composition composed substantially as described and for the purpose
