IMPROVEMENTS IN THE MANUFACTURE OF STOPPERS FOR BOTTLES AND OTHER ARTICLES
Year: 1873

page_text: LETTERS PATENT to Joseph John Perry, of Red Lion Square, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF STOPPERS FOR BOTTLES AND OTHER ARTICLES."
Scaled the 20th February 1874, and dated the 5th September. 1873.
PROVISIONAL SPECIFICATION loft by the said Joseph John Perry at
the Office of the Commissioners of Patents, with his Petition, on
the 5th September 1873.
I, JOSEPH JOHN PERRY, of Red Lion Square, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF STOPPERS FOR BOTTLES AND OTHER
ARTICLES," to be as follows:-
My Invention has for its object improvements in the manufacture of
that class of stoppers which are made hollow and of elastic india-rubber,
and my improvements refer to means whereby the cost of manufacturing
such description of stoppers is greatly reduced.

page_text: Heretofore such description of stoppers have been made in one piece
of india-rubber in the shape of a cylinder closed at one end and open at
the other, which necessitated the employment of moulds in their manu-
facture. These moulds are however somewhat costly, and when
manufacturing such description of stoppers by their means the process
is necessarily a slow and therefore expensive one.
Now according to my Invention I dispenso with the use of moulds in
the manufacture of india-rubber stoppers, and thereby chcapen and
facilitate their manufacture. For this purpose I make the stopper in
two parts, the body or cylinder thereof being formed of india-rubber
tube cut off to the length required, whilst the head or cap thereof is
formed of any suitable hard material. These two parts may be connected
together by either stretching the tube or cylinder over a portion of the
head or cap or by cementing them together, or in some cases the tube
may be fastened to the head or cap by means of wire or cord. Any:
suitable means may however be employed in connecting the two parts of
the stopper together.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph John Perry in the Great Scal Patent Office
on the 28th February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPп
JOHN PERRY, of Red Lion Square, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of September, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Mer reign, did, for Пerself, Her heirs and successors, give
and grant unto me, the said Joseph John Perry, Her special license, that
I, the said Joseph John Perry, my exccutors, administrators, and assigns,
or such others as I, the said Joseph John Perry, my executors, adminis-
trators, 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 Ircland, the Channel Islands, and

page_text: Isle of Man, an Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
STOPPERS FOR BOTTLES AND OTHER ARTICLES," upon the condition (amongst
others) that I, the said Joseph John Perry, my executors or adminis-
trators, 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 per-
formed, 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 Joseph John Perry, 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, reference being had to the Drawings here-
unto annexed and to the figures and letters marked thereon, that is to
say :-
My Invention has for its object improvements in the manufacture of
that class of stoppers which are made hollow and of elastic india-rubber,
or compounds thereof, or other al alogous gums, and my improvements
consist in a mode of manufacture whereby the cost of production of
such description of stoppers is greatly reduced.
Heretofore such description of stoppers have been made in one piece
of india-rubber or of compounds thereof or of other analogous gums in
the shape of a cylinder closed at one end and open at the other, which
mode of construction necessitated the employment' of moulds in their
manufacture. These moulds are however very costly, and when manu-
facturing such description of stoppers by their means the process is
necessarily a slow and therefore expensive one.
Now according to my Invention I dispense with the use of moulds in
the manufacture of such description of india-rubber stoppers, and
thereby facilitate and cheapen their manufacture.
In carrying my Invention into effect I make the stopper in two parts,
as shown in the accompanying Drawings, in which Figure 1 represents
a section of the stopper; Figure 2, a section of the head thereof
separately; and Figure 3, a section of the tubular or body part thereof.
The tubular or body part a of the stopper I form according to my
Invention of india-rubber tubing or of tubing formed of compounds

page_text: thereof, or of other analogous gums, cut off to tho length required, whilst
I form the head or cap thereof of any-suitable, hard material. Theso
two parts may be connected together by cementing them together by
the aid of india-rubber or other suitablo cement, or in some cases the
tubo a may be fastened to the head or cap by means of wire, thread, ₺
or cord wrapped and tied around them: Any suitable means may
howover be employed in connecting the two parts of the stopper
together.
When forming the head or cap 6 of tho stopper of porous material I
apply a coating of india-rubber or other suitable cement to the inner 10
part thereof in order to prevent the passage of air therethrough, and
therefore form a perfectly hermetical stopper..
·
Having thus described the nature of my said Invention and tho modo
in which I carry the same into effect, I would have it understood that
what I claim as my Invention, and desire to secure by Letters Patent, is 15
the mode of constructing hollow elastic stoppers in two parts in manner
substantially as herein shown and described in lieu of making them in
one piece in moulds as heretofore.
In witness whereof, I, the said Joseph John Perry, have hereunto
set my hand and scal, this Twenty-seventh day of February, in 20
the year of our Lord One thousand cight hundred and seventy-
four...
