page_text: LETTERS PATENT to Allen Oldroyd, of Clapton, in the County of Middlesex,
Manufacturer, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF TOBACCO AND OTHER POUCHES, PART OF SUCH IMPROVEMENTS BEING APPLICABLE
TO THE FRAMES OF OTHER BAGS OR RECEPTACLES."
Sealed the 22nd November 1867, and dated the 25th May 1867.
PROVISIONAL SPECIFICATION left by the said Allen Oldroyd at the
Office of the Commissioners of Patents, with his Petition, on the 25th
May 1867.
I, ALLEN OLDROYD, of Clapton, in the County of Middlesex, Manufacturer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF TOBACCO AND OTHER POUCHES, PART OF SUCH IMPROVEMENTS
BEING APPLICABLE TO THE FRAMES OF OTHER BAGS OR RECEPTACLES," to be as
follows:-
This Invention relates first to the manufacture of tobacco and other similar
pouches made of india-rubber. Heretofore when metal frames have been
used in combination with india-rubber pouches for closing the opening thereto,
the india-rubber tissue or sheet rubber forming the pouch has been secured to
the frame by rivetting or otherwise attaching it after the india-rubber has been
vulcanized, cured, or converted so as to render it permanently elastic by chemical
treatment, as is now well understood in the treatment of india-rubber for various
purposes.
Now according to my improvements I attach or connect the india-rubber
pouch to its frame by enclosing it in or covering it with the the edges of the

page_text: sheet rubber forming the pouch by means of india-rubber solution before it
is cured or converted by chemical agency to render it permanently elastic.
As the metal frame of the pouch is completely embedded in or covered by the
india-rubber, it is not in the least exposed to the corrossive action of the chemicals
to which the india-rubber forming the pouch is subjected in order to convert or
cure the same.
The second part of my improvements consists in forming india-rubber,
tobacco, or other pouches (combined or made up with a hinged metal frame
as previously described according to the first part of my improvements) with
two separate pouches or receptacles, one of such pouches being attached to
one part or half of the hinged metal frame, and the other to the other part
or balf of the metal frame employed for closing the opening to such pouches.
In carrying out this part of my improvements I prefer to make the hinged
metal frame of circular or of oval shape, at the same time I do not confine
myself to these particular forms, and in making such frames intended to be
covered with india-rubber as previously described it is necessary to leave
sufficient space between the two parts when they are closed or come together
for the spring snap or other fastening to act when each part of the frame is
covered with the india-rubber forming part of the pouch. A folding flap is
applied to cover one of the parts of pouch, thus forming a division between
the two..
t
The third part of my improvements consists in covering or embedding the
inetal frames of bags or receptacles, first with uncured india-rubber and
afterwards subjecting the same to chemical treatment to "convert" or change
the character of the india-rubber so treated as is well understood. The
process I prefer to employ for this purpose is to expose the india-rubber after
it is applied to or combined with so as to cover the metal frame to the fumes
of chloride of sulphur produced by heat in a closed chamber as is now well
understood in the manufacture of pouches and other articles made of india-
rubber. The metal frames thus covered with india-rubber may be made up
with leather or other materials into bags or other receptacles, a very neat and
finished appearance being thus given to the frames so covered; suitable holes.
may be left in the metal frames for the purpose of sewing, rivetting, or otherwise
attaching such frames to the leather, cloth, or other material employed to form
the bag or receptacle.

by the said Allen Oldroyd in the Great Seal Patent Office on the 25th
November 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALLEN
OLDROYD, of Clapton, in the County of Middlesex, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of May, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Allen Oldroyd, Her special licence, that I, the said Allen Oldroyd, my exe-
cutors, administrators, and assigns, or such others as I, the said Allen Oldroyd,
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 THE MANUFACTURE OF TOBACCO AND
OTHER POUCHES, PART OF SUCH IMPROVEMENTS BEING APPLICABLE TO THE FRAMES
OF OTHER BAGS OR RECEPTACLES," upon the condition (amongst others) that
I, the said Allen Oldroyd, my executors or administrators, by an instru-
ment 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Allen Oldroyd, 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 relates, first, to the manufacture of tobacco and other
similar pouches made of india-rubber. Heretofore when metal frames have
been used in combination with india-rubber pouches for closing the opening
thereof, the india-rubber tissue or sheet rubber forming the pouch has been,
secured to the frame by rivetting or otherwise attaching it after the india-
rubber has been vulcanized, cured, or converted so as to render it permanently.
elastic by chemical treatment, as is now well understood. in the treatment of
india-rubber for various purposes.
Now according to my improvements I attach or connect. the india-rubber

page_text: pouch to its frame by enclosing it in or covering it with the edges of the sheet
rubber forming the pouch by means of india-rubber solution before it is cured
or converted by chemical agency to render it permanently elastic. As the
metal frame of the pouch is completely embedded in or covered by the india-
rubber, it is not in the least exposed to the corrosive action of the chemicals
to which the india-rubber forming the pouch is subjected in order to convert
or cure the same.
The second part of my improvements consists in forming india-rubber
tobacco or other pouches (combined or made up with a hinged metal frame,
as previously described according to the first part of my improvements) with
two separate pouches or receptacles, one of such pouches being attached to
one part or half of the hinged metal frame and the other to the other part or
half of the metal frame employed for closing the opening to such pouches.
In carrying out this part of my improvements I prefer to make the hinged
metal frame of circular or of oval shape, at the same time I do not confine
myself to these particular forms; and in making such frames intended to be
covered with [india-rubber, as previously described, it is necessary to leave
sufficient space between the two parts when they are closed or come together
for the spring snap or other fastening to act when each part of the frame is
covered with the india-rubber forming part of the pouch. A folding flap is
applied to cover one of the parts of the pouch, thus forming a division between
the two.
And in order that my Invention may be most fully understood and readily
performed or carried into practice, I will proceed to describe the Drawings
hereunto annexed..
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a transverse section of an india-rubber tobacco pouch
formed or made up with a covered metal frame, and with two separate
receptacles a and 6 for tobacco, in accordance with the first and second parts
of my improvements; Figures 2 and 3 show a plan and section of the same
pouch open; Figure 4 shews a plan and section of the hinged metal frame c
before it is covered; and Figure 5 shows a plan and section of one half of
such metal frame c when covered by the tubular ring c of uncured india-
rubber, shown at Figure 6. In order to cover the hinged frame c with the
uncured india-rubber it is separated by withdrawing the pin of the hinge
which connects the two parts together; a tubular ring of india-rubber, such
as shown at Figure 6, is then stretched around each separate part of the
frame c; the edges of the india-rubber are then brought in contact and

page_text: cemented together so as to encase each separate part of the frame. The pro-
jecting parts of the hinge c are passed through slits cut in the india-rubber
rings c¹, such projecting parts of the hinge when connected. together by the
pin being covered over with a separate piece of india-rubber cemented to the
rubber which covers the frame (as shewn at *, Figures 1, 2, and 3). The
spring catch c is protected during the process of curing by a coating of
varnish or by a piece of india-rubber cemented over it which is afterwards cut
away to allow the spring catch to act, and thus secure the two parts together
when closed. Each separate pouch or receptacle a, b, is formed by connecting
the outer cut edge or circumference of a flat ring of uncured india-rubber to
the outer cut edge or circumference of a flat disc of uncured india-rubber ;.
the two parts thus connected will form a cup-shaped receptacle, as shown at,
Figure 7, the upper edge of which is afterwards connected to the uncured
cover of the frame cat c by cementing it thereto, by which means each
separate pouch or receptacle a and b is thus formed. d is a folding flap
attached to one side of one of the receptacles a or 6 near the hinge, so that
when the other side is tucked under the opposite side it forms a division.
between the contents of the two receptacles a and b; if desired one or both
of the receptacles may be partially covered by a diaphragm. of india-rubber
attached to the inner edges thereof.
From the previous description it will be evident that other forms of hinged
frames may be employed and covered with uncured india-rubber for the-
manufacture of india-rubber tobacco and other pouches previous to being cured
in accordance with this part of my Invention.
The third part of my improvements consists in covering or embedding the
metal frames of bags or other receptacles, first, with uncured india-rubber
and afterwards subjecting the same to chemical treatment to convert or change
the character of the india-rubber so treated, as is well understood. The
process I prefer to employ for this purpose is to expose the india-rubber (after
it is applied to or combined with so as to cover the metal frame) to the
fumes of chloride of sulphur produced by heat in a closed chamber, as is now
well understood in the manufacture of pouches and other articles made of
india-rubber. The metal frame thus covered with india-rubber may be made
up with leather or other material into bags or other receptacles, a very neat
and finished appearance being thus given to the frames so covered. Suitable
holes may be left in the metal frames for the purpose of sewing, rivetting, or
otherwise attaching such frames to the leather, cloth, or other material
employed to form the bag or receptacle.
Having thus described the nature of my Invention, and the manner of per-

page_text: forming or carrying the same into practice, I would have it understood that I
do not confine myself to the exact details herein described so long as the
peculiar character of either part of my Invention is retained; but what I
claim is,―
First, the manufacture of india-rubber tobacco and other pouches con-
structed with hinged metal frames, as herein described, by first covering the
metal frame with uncured india-rubber and attaching the pouch or receptacle
thereto, the pouch so made up being afterwards vulcanized or chemically treated
in order to render the india-rubber permanently elastic, as is well understood.
Secondly, I claim the manufacture of india-rubber tobacco and other
pouches with two separate receptacles combined with a metal frame, as herein
described and shewn in the accompanying Drawing.
And, thirdly, I claim the covering of metal frames for bags or other recep-
tacles with uncured india-rubber, as herein described, and afterwards sub-
jecting the same to chemical treatment to change or convert the india-rubber,
as is well understood in the treatment of other articles composed of india-
rubber.
In witness whereof, I, the said Allen Oldroyd, have hereunto set my
band and seal, this Twenty-second day of November, in the year of
our Lord One thousand eight hundred and sixty-seven.
