Sealed the 31st March 1857, and dated the 2nd October 1856.
PROVISIONAL SPECIFICATION left by the said Charles Goodyear at the
Office of the Commissioners of Patents, with his Petition, on the
2nd October 1856.
I, CHARLES GOODYEAR, of Leicester Square, in the County of Middlesex,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN SECURING
THE OPENINGS OF AIR-TIGHT AND OTHER BAGS AND PACKAGES," to be as follows:-
This Invention consists in a method of securing the openings or mouths of
bags or packages made of waterproof or other fabric. For this purpose the
edges of the opening or mouth are made with flanges or enlargements, which
when the package is to be closed are brought together, and a clamp made in
the form of a split tube is slid over them, which by means of screws is caused
to press the edges of the opening together, so as to make an air-tight joint;
or the bag or package may have a ring of metal or other rigid material fixed
to it round the edges of the mouth or opening, and into the ring a door or
plug is made to fit, and the door or plug, or its seat, is lined with elastic
material, and is pressed firmly into its seat, and secured by screw fastenings or
otherwise.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of October, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles Goodyear, Her special licence that I, the said Charles Goodyear, my
executors, administrators, and assigns, or such others as I, the said Charles
Goodyear, 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 SECURING
THE OPENINGS OF AIR-TIGHT AND OTHER BAGS AND PACKAGES," upon the condition
(amongst others) that I, the said Charles Goodyear, 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 Charles Goodyear, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say:-
This Invention consists in a method of securing the openings or mouths of
bags or packages made of waterproof or other fabric. For this purpose the
edges of the opening or mouth made with flanges or enlargements, which
when the package is to be closed and brought together, and a clamp made in
the form of a split tube is slid over them, which by means of screws is caused
to press the edges of the opening together, so as to make an air-tight joint ; or
the bag or package may have a ring of metal or other rigid material fixed to
it round the edges of the mouth or opening, and into the ring a door or plug
is made to fit, and the door or plug, or its seat, is lined with elastic material,
is pressed firmly into its seat, and secured by screw fastenings or otherwise.

page_text: Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows the section of a bag with apparatus, according to my
Invention, applied thereto; Figure 2 is a side view thereof. a, a, is the bag,
made of or lined with waterproof material. The form and construction of the
bag may be varied, and, separately, is not claimed. At the mouth of the bag
there is introduced vulcanized india-rubber. At b, b, and c, c, is a clamp, which
has spring clamping pieces d, d, with screws e, e, as shown; the form of the
clamping apparatus may however be varied. In some cases, in place of
making the mouth of a bag to close, as above explained, I have a frame
or ring around the mouth of the bag, together with a metal door or lid; the
parts of the ring or frame, and the door or lid which come together, are lined
with vulcanized india-rubber or suitable waterproof flexible material.
In witness whereof, I, the said Charles Goodyear, have hereunto set my
hand and seal, this Thirty-first day of March, in the year of our Lord
One thousand eight hundred and fifty-seven.
Witness,
E. BARKER.
CHARLES GOODYEAR. (L.S.)
