PROVISIONAL SPECIFICATION.
Improvements in Air and Waterproofing Varnishes or Compositions.
I, JOHN LEITCH POLLOCK of 5 Rue St. Cecile, Paris in the Republic of
France, do hereby declare the nature of this invention to be as follows:-
This invention relates to a composition for forming a coating or varnish of any
desired thickness for protection against air and water; for treating substances and
objects generally, especially straw and other hats and bonnets.
The composition is as follows :-
Acetone
Acetic ether
Sulphuric ether
Camphor
Gum-lac
Cotton
Paper
Mastic in drops

These proportions give good results, but they may be slightly varied.
In manufacturing the composition I dissolve the paper in the sulphuric acid
after breaking it up; the cotton is dissolved in the same manner in the acetone,
then all the other materials are added with these two solutions in the same vat
and thoroughly mixed by stirring them up, and are then ready for application by
a brush; when applied and dry the composition forms a true impermeable skin.
Dated this 4th day of February 1896.

All and
I, JOHN LEITCH POLLOCK of 5 Rue. St. Cecile, Paris. in. the Republic of
France, 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:-
This invention relates to a new product, which, deposited upon any object forms
a coating of more or less thickness, analogous to a skin which is absolutely
impermeable, and is not apt to scale off or be deteriorated by the influence of the
atmosphere or of water.
This product is susceptible of receiving numerous applications and to replace

1,000 grammes.
These proportions are not absolute and although they have given me the best
results, I may vary them according to their applications. I first dissolve paper
in sufficient sulphuric acid for that purpose, without application of heat after
having broken it up by means of any appropriate apparatus. The cotton is
dissolved in the same manner in the acetone, then all the other materials mentioned
above are mixed with these two solutions in the same vat and well mingled by
means of a stirring rod.
The product so obtained is applied in the same way as other varnishes usually
by means of a brush upon the object to be protected and forms, when it is dry, a
true pellicle or protecting skin, which will not crack or peel off and which is
absolutely impermeable..
This varnish is suitable at any time, when an object is to be protected against
humidity whether the object be of wood, metal or any other material, but its use
is especially desirable in the hat trade for rendering hats of straw or cloth
impermeable.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that what I
.-claim is :-
A product for rendering impermeable hats and other objects covered with it
and forming a skin or pellicle on their surface, composed of acetone, acetic ether,
sulphuric ether, camphor, gum lac, cotton, paper and mastic in drops substantially
as described.
Dated this 28th day of October 1896.
