I, JAMES GEORGE INGRAM of Felstead Street, Hackney Wick in the County of
Middlesex, India Rubber Manufacturer, do hereby declare the nature of this invention
to be as follows:-
In the manufacture of pouches of the "Horsey" pattern and some other forms of
pouches, the pouch is formed of a number of pieces of sheet rubber cut to the proper
shape and cemented together at their edges.
It frequently results from this method of manufacture that even comparatively new
pouches come apart at the joins and thus render the pouch useless.
Now the object of my invention is to entirely remove this objectionable feature
by forming the pouch without any join or seam therein.
For this purpose I form a mould to the shape of the pouch required to be
produced and I then by the process of dipping produce thereon a pouch of any
desired thickness and entirely without a seam.
The folds or corners of the pouch are preferably strengthened, before, intermediate
of, or after the dipping process, by means of pieces of rubber, or rubber or other
fabric an opening is then formed in the pouch and the raw edges or lips are
strengthened in any suitable manner.
The complete pouch is then aired in any well known and suitable manner after
which the mould is removed through the opening formed therein.
The rubber solution to form the pouch may be coloured in any desired manner or
the colour may be applied to the pouch at any other stage of the manufacture.

Improvements in the Manufacture of Tobacco Pouches.
I, JAMES GEORGE INGRAM of Felstead Street, Hackney Wick, in the County of
Middlesex, India Rubber Manufacturer do hereby declare the nature of this invention,
and in what manner the same is to be performed, to be particularly described and
ascertained, in and by the following statement :-
In the manufacture of tobacco pouches of the "Horsey" pattern, and of some
other forms, the pouch is manufactured of a number of pieces of sheet india rubber,
cut to the proper shapes and cemented together at their edges.
It frequently results from this method of manufacture, that even comparatively new
pouches come apart at the joins and thereby become useless.
Now the object of my invention is to entirely remove this objectionable feature by
forming the pouch without any join or seam therein.
I will describe my invention as applied to the manufacture of the "Horsey" pouch,
such as represented in face view and longitudinal section in its extended or open
position at Figures 1 and 2.
For this purpose 1 form a mould b, as represented at Figures 3 and 4, of any
suitable metal or alloy to the shape of the interior of the pouch a required to be
produced, and I then, by the process of dipping the said mould b into a solution of
india rubber, or of any desired india rubber compound, produce on such mould a
coating of any desired thickness entirely without seam.
The corners of the pouch a are preferably strengthened by means of pieces a' of
india rubber, or of india rubber, or other, fabric, which may be applied to the mould b,
before commencing the dipping process, or may be placed in proper position after a
thin coating of india rubber has been formed on the mould b, then, by the dipping,
or further dipping, of the mould into the solution, the said strengthening pieces
are firmly secured in position either on the inside of the pouch or intermediate of
the thickness thereof. These strengthening pieces may however be applied to the
pouch after the same is formed on the mould.
When the desired thickness of india rubber or of india rubber compound, has been
obtained upon the mould b, an opening a² is cut therein, so as to form the lips a³, a*,
of the pouch and the raw edge of the lip a is then strengthened by turning over
a portion of the material forming the body of the pouch, or it may be strengthened in
other suitable manner.
The completed pouch is then curved or vulcanized in any well known and suitable
manner, after which the mould is removed from the pouch a through the opening a²
between the lips thereof.
The rubber solution or compound to form the pouch may be colored in any
desired manner, or color may be applied to the pouch a at any other stage of the
manufacture.
To facilitate the manipulation of the mould b, a wire c may be fixed in one end
thereof and the other end of such wire may be removably fixed to a board d by

page_text: means of clamps d', a number of such moulds being preferably arranged on one
board, by which means they can be simultaneously dipped into the solution. On
removal of the moulds from the solution after each dipping process, the surplus
solution collected at the lower edge thereof is carefully removed, after which the
moulds are reversed in position by standing the board d on a table or other support,
by which means the thickness of the coating is equalized.
When it is desired to remove the pouch from the mould, the wire c is released from
the clamp d and the pouch is drawn off the mould, the wire c passing through the
small hole formed in the pouch thereby:
When using comparatively thick wires c to support the moulds b, a hole is formed
in one end of the pouch, which, if desired, may be stopped before submitting the
pouch a to the curing or vulcanizing process.
€
If desired, however, the construction of mould represented at Figure 5 may be
employed in carrying my invention into effect; in this case a small tube is cast
within the thickness of the mould and from end to end thereof and a countersunk
hole 6 communicating with such tube b¹ is made in the centre of the mould, a very
thin supporting wire c is then passed through the hole and out through one end
of the tube b', the ends c¹, c, of such wire care hent, as shown, so as to enable the
mould to be suspended from a suitable dipping board or frame, a similar wire c being
inserted from the other end of the tube to enable the mould to be readily reversed
in position when required; then, when the pouch is completed, the wires c have
their ends c¹, c³, cut off, and are then pulled out of the mould, when it will be
found that only very small and unimportant holes have been made thereby in the
pouch.
It will be understood that other forms of tobacco pouches may be manufactured in a
similar manner to that above described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is
1. The manufacture of tobacco pouches by the process of dipping a suitably shaped
mould into a solution of india rubber or of india rubber compound and then finishing
them in manner substantially as herein described and for the purpose stated.
2. A tobacco pouch manufactured by dipping a suitably shaped mould into a
solution of india rubber or of india rubber composition and strengthened at the
corners by pieces of india rubber or other suitable material applied to the mould
before dipping or before the full thickness of india rubber has been obtained thereon
substantially as herein described.
