for coating the bottoms of ships for the purpose of increasing their
speed, and for other purposes.
In some cases I mix with this pulp colouring matter, cohesive
materials, such as glue and glycerine, for the purpose of softening.
My Invention also consists in making from the intestines of animals
flat bands for driving machinery. For this purpose I take the intestines
of animals, and after washing and freeing them of all oleaginous matter
I soak them in water, and having stretched them I place them together
in layers to obtain the desired thickness.
The surfaces of the intestines can be rendered more adhesive by using
glue or other analagous substances. In some cases I soften them by
means of glycerine. I afterwards pass them through rollers, or otherwise
press them, dry them, and cut them to the required lengths.
SPECIFICATION in pursuance of the conditions or the Letters ratent,
filed by the said John Macintosh in the Great Seal Patent Office
on the 20th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MACINTOSH, of Westminster, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of November, in
the year of our Lord One thousand eight hundred and seventy-five,
in the thirty-ninth year of Her reign, did, for Herself, Her heirs
and successors, give and grant unto me, the said John Macintosh,
Her special licence, that I, the said John Macintosh, my executors,
administrators, and assigns, or such others as I, the said John
Macintosh, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of

page_text: Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "CERTAIN IMPROVEMENTS IN TREATING THE TISSUES AND IN-
TESTINES OF ANIMALS, AND FOR THE APPLICATION THEREOF TO CERTAIN USEFUL
PURPOSES," upon the condition (amongst others) that I, the said John
Macintosh, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, 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
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Macintoshi, do hereby declaro
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:-
My Invention consists in the following treatment and application
of animal tissues, intestines, and the like, that is to say :-I take the
tissues and intestines of animals and reduce them to a pulp by grinding
after washing and freeing them of all oleaginous matter; with this pulp
I saturate a coat, cloth, or felt, or cotton fleece, which I employ for
making flat bands for driving machinery, or for coating the bottoms of
ships for the purpose of increasing their speed, and for other purposes.
For coating ships' bottoms I sometimes mix with the ground intestines
ground fish skins to render the surface more slippery.
In some cases I mix with the pulpy matter cohesive materials, such as
glue and glycerine, for the purpose of softening the same.
My Invention also consists in making from the intestines of animals
flat bands for driving machinery. For this purpose I take the intestines
of animals, and after washing and freeing them of all oleaginous matter
I soak them in water, and having stretched them I place them together
in layers to obtain the desired thickness.
The surfaces of the intestines can be rendered more adhesive by using
glue or analogous substances. In some cases I soften them by means
of glycerine. I afterwards pass them through rollers, or otherwise press
them, dry them, and cut them to the required length.
