Year: 1873

page_text: LETTERS PATENT to John Macintosh, of Bayswater, in the County
of Middlesex, for the Invention of "IMPROVEMENTS IN TOBACCO
POUCHES OR RECEPTACLES FOR CONTAINING TOBACCO, APPLICABLE TO OTHER
PURPOSES."
PROVISIONAL SPECIFICATION left by the said John Macintosh at
the Office of the Commissioners of Patents, with his Petition, on
the 24th June 1873.
I, JOHN MACINTOSH, of Bayswater, in the County of Middlesex, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
TOBACCO POUCHES OR RECEPTACLES FOR CONTAINING TOBACCO, APPLICABLE TO OTHER
PURPOSES," to be as follows:-
:
The object of my Invention is to lessen the cost and weight of the
above articles by making them without frames, draw strings, twisting or
doubling folds of india-rubber for rendering the opening air-tight as
heretofore used.
・

page_text: In accordance with my Invention I make an opening in the india-
rubber or other flexible material, which is covered with a flexible flap,
overlapping the opening on the under side, rendering the joint air-
tight.
It will be readily understood that applying this Invention to rigid
vessels the flap must overlap the under side to insure a fluid or liquid
tight joint.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Macintosh in the Great Seal Patent Office on
the 24th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MACINTOSH, of Bayswater, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of June, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh 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 Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
TOBACCO POUCHES OR RECEPTACLES FOR CONTAINING TOBACCO, APPLICABLE TO OTHER
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 Macintosh, do hereby declare
the nature of my said Invention, and in what manner the same is to be.

page_text: performed, to be particularly described and ascertained in and by the
following statement:-
The object of my Invention is to lessen the cost and weight of the
above articles by making them without frames, draw strings, twisting
or doubling folds of india-rubber for rendering the opening air-tight as
heretofore used.
In accordance with my Invention I make an opening in the india-
rubber or other flexible material, which is covered with a flexible flap
overlapping the opening on the under side, rendering the joint air-
tight.
It will be readily understood that applying this Invention to rigid
vessels the-flap must overlap the under side of the opening, or it may be
attached to the opening to insure a fluid or liquid tight joint.
A flexible valve kept in the required position during vulcanization
will remain permanently in such position. This valve may be applied
to every description of. hollow vessel which is not subjected to more than
a certain amount of heat.
In some cases an opening may be made in vessels already vulcanized,
and a piece of india-rubber or other flexible material attached to form a
valve as above described.
The above Invention being so simple that any ordinary worker of
india-rubber can at once understand it I deem it wholly unnecessary to
add any Drawings.
In witness whereof, I, the said John Macintosh, have hereunto set
my hand and seal, this Twenty-fourth day of December, in the
year of our Lord One thousand eight hundred and seventy-
three.
JOHN MACINTOSH. (L.S.)
