IMPROVEMENTS IN STOPPERS FOR BOTTLES, JARS, AND OTHER HOLLOW ARTICLES
Year: 1874

page_text: LETTERS PATENT to Nathan Thompson, of Brooklyn, New York, in
the United States of America, but at present of 23, Southampton
Buildings, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN STOPPERS FOR BOTTLES, JARS, AND OTHER HOLLOW
ARTICLES."
PROVISIONAL SPECIFICATION left by the said Nathan Thompson at
the Office of the Commissioners of Patents, with his Petition, on
the 5th November 1874.
I, NATHAN THOMPSON, of Brooklyn, New York, in the United States
of America, but at present of 28, Southampton Buildings, in the County
of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN STOPPERS FOR BOTTLES, JARS, AND OTHER HOLLOW ARTICLES,"
to be as follows:-
The present Invention has for its object improvements upon an
Invention for which I obtained Letters Patent on the Twenty-ninth
day of August last, No. 2961. For this purpose instead of forming

page_text: the wing pieces to turn upon hinge or pin joints, as described in my
Provisional Specification filed with the application aforesaid, I form
such wing pieces to slide to and fro in right lines on suitable guides
formed on the cap or cover. This by preference I effect in the following
manner: On the cap or cover I form in the process of stamping the t
same out of sheet metal two recesses on the top in a line with each
other, and projecting up from such recesses are studs or projections
also formed by stamping them out of the metal forming the cap or
cover.
The wing pieces are also by preference stamped out of sheet metal,
and have formed thereon guide pieces which fit into the recesses in the
cap or cover, and each of such wing pieces is formed with a slotted, hole,
through which holes pass the studs or projections from the cap or cover.
These studs or projections are then turned down' over the sides of the
slotted holes so as to hold the wing pieces in position and act as guides
thereto. Each wing piece has also formed therein by the process of
stamping a raised loop or eye, which loops or eyes can be readily secured
together by wire passed therethrough, and lying in a recess formed in
the top of the cap or cover. By these means the stopper is reduced in
cost, and the construction thereof considerably simplified and improved.
In some cases more than two of such wing pieces constructed and
operated as above described may be employed.
The second part of my Invention also consists in an improvement
upon my Invention before referred to. For this purpose instead of
forming the wing pieces to turn on hinge or pin joints, so that the outer
end of one is placed on one side, and the outer end of the other is placed
on the other side of the cap or cover, I so hinge or pin joint them and
increase their length, that when closed upon the cap or cover, the outer
ends thereof shall meet or nearly so, and I form at the ends thereof
raised loops or eyes by stamping as before described with reference to
the first part of my present Invention, so as to enable them to be secured
together by wire, and thereby enable me to dispense with the pin-jointed
locking bar described in my Provisional Specification before referred to.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Nathan Thompson in the Great Seal Patent Office
on the 5th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHAN
THOMPSON, of Brooklyn, New York, in the United States of America,
but at present of 23, Southampton Buildings, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of November, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Nathan Thompson, Her special license that I,
the said Nathan Thompson, my executors, administrators, and assigns, or
such others as I, the said Nathan Thompson, 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 STOPPERS FOR Bottles,
JARS, AND OTHER HOLLOW ARTICLES," upon the condition (amongst others)
that I, the said Nathan Thompson, 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 Scal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, tho said Nathan Thompson, 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 :-
The present Invention has for its object improvements upon an
Invention for which I obtained Provisional Protection on the 29th day
of August last, No. 2961. For this purpose instead of forming the wing
pieces to turn upon hinge or pin joints, as described in my Provisional
Specification filed with the application aforesaid, I form such wing

page_text: pieces to slide to and fro in right lines on suitable guides formed on the
cap or cover. This by preference I effect in the following manuer :—
-On
the cap or cover I form in the process of stamping the same out of
sheet metal two recesses on the top in a line with each other, and
projecting up from such recesses are studs or projections also formed by
stamping them out of the metal forming the cap or cover.
The wing pieces are also by preference stamped out of sheet metal, and
have formed thereon guide pieces which fit into the recesses in the cap
or cover, and each of such wing pieces is formed with a slotted hole,
through which holes pass the studs or projections from the cap or cover.
These studs or projections are then turned down over the sides of the
slotted holes, so as to hold the wing pieces in position and act as guides
thereto. Each wing piece has also formed therein by the process of
stamping a raised loop or eye, which loops or eyes can be readily secured
together by wire passed therethrough, and lying in a recess formed in
the top of the cap or cover. By these means the stopper is reduced in
cost and the construction thereof considerably simplified and improved.
In some cases more than two of such wing pieces constructed and
operated as above described may be employed.
The second part of my Invention also consists in an improvement upon
my Invention before referred to. For this purpose instead of forming
the wing pieces to turn on hinge or pin joints so that the outer end of
one is placed on one side, and the outer end of the other is placed on the
other side of the cap or cover, I so hinge or pin joint them and increase
their length, that when closed upon the cap or cover, the outer ends
thereof shall meet or nearly so, and I form at the ends thereof raised
loops or eyes by stamping as before described with reference to the first
part of my present Invention, so as to enable them to be secured together
by wire, and thereby enable me to dispense with the pin-jointed locking
bar described in my Provisional Specification before referred to.
And in order that my said Invention may be clearly understood and
readily carried into effect, I will proceed aided by the accompanying
Drawings, fully to describe the same.

other article, and
Figure 18 represents an under side view of the stopper.
«, Figure 2, represents a flange formed on the neck of a bottle, jar, or
other hollow article, to enable the stopper to be fixed thereon.
b represents a metal cap, in which a cork c is fixed by means of
cement or by means of wire passing through such cork and through the
cap b, on the outside of which the wire is soldered so as to prevent the
passage of air through the cap 6 at such part, or the cork c may be fixed
in any other convenient and suitable manner. Around the cork c I
place a ring of india-rubber d, in order that on pressure being applied to
the cap or cover b, the india-rubber may be compressed between the
6 and the upper edge of the flange a.
Other suitable material may
cap
however be employed in lieu of the cork and india-rubber.
The stopper represented at Figures 1 to 10, is provided with two
sliding wing pieces e, which are formed with flanges e¹ to come under
the flange a, and thereby hold the stopper firmly in position. These
wing pieces are guided by means of staples ✓ passing through slits or

page_text: And, Fourthly. I claim when employing sliding wing pieces e, forming
a recess in the cap or cover b, to enable the fastening wire to lie flush
therein, in manner substantially as herein shown and described.
In witness whereof, I, the said Nathan Thompson, have here-
unto set my hand and seal, this Fifth day of May, in the
year of our Lord One thousand eight hundred and seventy-
five.
