use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN HATS, AND IN THE PREPARATION OF PLUSH OR OTHER
COVERING USED IN THE MANUFACTURE OF HATS," upon the condition
(amongst others) that I, the said John Talbot Tyler, by an instru-
ment in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-

.
NOW KNOW YE, that I, the said John Talbot Tyler, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say):
The nature of my Invention consists in making hats waterproof,
elastic, and pliant, in coating or covering the material from which the
bodies are made, or the outside of hat bodies, with a waterproof elastic
composition rendered adhesive by heat, and in coating or covering the
back of plush or other covering for hats with the like composition.

page_text: I produce a waterproof, elastic, and pliant hat by causing the plush
or other covering of a body to adhere to the body by means of caout-
chouc in a liquid state, or of a cement or other adhesive composition
wherein caoutchouc is greatly in excess. I find the following a good
composition for the purpose:-I dissolve 14 ounces of caoutchouc in a
solvent composed of two parts of coal tar naptha to one part oil of tur-
pentine, or in either of these substances by itself. I spread the com-
position by a brush, or by other suitable means, on the back of the plush
or other covering for the hat, and in some cases I also spread the com-
position on the body, or I spread it on the body only. I then lay the
covering on the body, previously placed on a block, and cause the plush
or other covering to adhere thereto by passing a heated iron over and
round the outside of the plush or other covering.
When the body is of felt or other like soft material, by following the
process above described, I produce a hat perfectly soft, pliant, and
waterproof.
Having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my
improvements in the manufacture of hats,-
First, the rendering the same soft, pliant, and waterproof by spread-
ing the aforesaid composition either on the outer surface of the body
of the hat, or on the inner surface or back of the plush or other cover-
ing for the bodies of hats, or on both, and causing the same to adhere
by means of a heated iron or other equivalent, all as herein-before
described.
And, second, I claim the preparation of plush or other covering used
in the manufacture of hats by coating the back or inside thereof with
the waterproof composition herein-before described, rendered adhesive
by the application of heat.
In witness whereof, I, the said John Talbot Tyler, have hereunto
set my hand and seal, this Eighth day of April, One thousand
eight hundred and fifty-three.
