Park, in the county of Essex, Gentleman, for an invention of "IMPROVEMENTS
IN TOBACCO POUCHES."
PROVISIONAL SPECIFICATION left by the said Benjamin Leon James at
the Office of the Commissioners of Patents on the 6th May 1882.
BENJAMIN LEON JAMES of Mornington Villas Wanstead Park in the County of
Essex, Gentleman, IMPROVEMENTS IN TOBACCO POUCHES
This Invention has reference to the manufacture of Tobacco Pouches which
admit of very easy access to the contents and by the exclusion of the air the
tobacco is kept in the best possible condition. In making these pouches two pieces
of rubber are cut from a sheet of the prepared material, these pieces may be of any
desired shape either circular, octagonal, rectangular or other figure. The edges of
the pieces are turned in and fastened with naptha or " solution." A small hole is
left in the bottom at the junction of the parts, to admit of the bag being partly
filled with water, after which the hole is plugged with a small piece of rubber
dipped in naptha; the water thus serving as a flexible core during the subsequent
moulding process. A cap piece of a crescent shape which forms the enclosing cover
is fastened to the lower part of the pouch, leaving about two thirds of it to form
the moveable cap which slides on and off sideways or in a lateral direction a
feature which distinguishes this pouch from all others. The cap corresponds in
figure with the thickened lower part of the pouch, so that when closed it presents
a smooth uniform surface. French chalk or other suitable material is interposed
between the body of the pouch and the cap to prevent those parts adhering. The
pouch is then placed in a suitable mould and submitted to the vulcanizing process,
and when cold it is taken from the mould, the cap is thrown back and the opening
of the pouch is made by cutting round a portion of the edge a rim inside the
enclosing cap. This part may or may not be further enclosed by a small over-
lapping flap piece. Pouches made in this manner entirely prevent the escape of
dust or small particles of tobacco from passing into the pocket and in this respect
they are far more efficient than any others now in use.

BENJAMIN LEON JAMES of Mornington Villas Wanstead Park in the County of
Essex Gentleman "IMPROVEMENTS IN TOBACCO POUCHES
"
This Invention consists in a novel construction of india rubber tobacco pouch
which while excluding the air from the interior will allow of ready access to
the contents.
In carrying out this Invention two pieces of the size and shape according to the
form of the pouch to be made are cut from a sheet of rubber compound and the
edges of these pieces are joined together by means of solution to form a bag. A
cap piece is then applied to the bag and is so arranged as to open laterally. The
pouch thus formed is subjected to vulcanization in the usual way.
In the accompanying drawing, Fig: 1 is a front view of a closed pouch
constructed according to my Invention. Fig: 2 is a front view of the pouch with
the cap piece thrown back, and Fig: 3 is a plan view of the pouch open.
In the drawing the pouch is shewn as of a circular form, but it may be of any
other suitable form, as octagonal or rectangular.
A A¹ are two pieces cut from a sheet of rubber compound. These pieces are
joined at their edges by means of solution in the usual way or in any other suitable
manner. A small quantity of water is placed in the bag thus formed to serve as
an elastic core during the subsequent operation of moulding and vulcanizing as is
well understood.
Outside the bag is placed a cap piece B also formed of two pieces B B¹ cut from
a sheet of rubber compound. These pieces are joined together where required by
solution or otherwise. The exact size of this cap piece may vary but for a circular
pouch I prefer it shall be about two-thirds the size of the pouch as shewn in the
drawing. This cap piece is attached to one side of the pouch so that it may be
thrown back laterally of the pouch as shown in Figures 2 and 3.
The bag A with the cap piece B attached thereto is placed in a mould of the
form and size of the pouch it is desired to make, and is then subjected to the
vulcanizing process in the usual manner. When withdrawn from the mould
the pouch will be found to have taken the form of the mould and have received
the proper "set" which it will always retain.
To prevent the cap piece B adhering to the bag A during the vulcanization
French chalk or other suitable material is placed between the parts
To remove the water core from the pouch and also to form the mouth of the
pouch an opening is made with a knife say along the dotted line Fig: 2.
In addition to the cap piece B a small flap C may be attached to the bag A before
vulcanization. This flap will serve to keep the mouth of the bag closed and
prevent dust or fine particles of tobacco escaping into the pocket of the owner.
Having now described the nature of my Invention of " Improvements in
Tobacco Pouches" and explained the manner of carrying the same into effect,
I claim:
Constructing vulcanized india rubber tobacco pouches with a cap piece opening
laterally of the pouch substantially as herein shewn and described.
In witness whereof I the said Benjamin Leon James have hereunto set my
hand and seal this second day of November in the year of our Lord One
thousand eight hundred and eighty two.
