IMPROVEMENTS IN STOPPERS FOR BOTTLES, JARS AND OTHER HOLLOW ARTICLES "
Year: 1882

page_text: LETTERS PATENT to Nathan Thompson of Brooklyn in the County of Kings
and State of New York in the United States of America but at present of
23 Southampton Buildings in the County of Middlesex for an 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 on the 29th September 1882.
NATHAN THOMPSON of Brooklyn in the County of Kings and State of New York
in the United States of America, but at present of 23 Southampton Buildings in
the County of Middlesex "IMPROVEMENTS IN STOPPERS FOR BOTTLES, JARS AND
OTHER HOLLOW ARTICLES"
:
The Invention has for its object improvements in stoppers for bottles, jars and
other. hollow articles whereby the stopper is readily locked in position on the
bottle neck, and released therefrom whilst a neat, compact and efficient arrangement
is obtained.
For this purpose I form the stopper with a hollow cap lined or fitted with cork
or other suitable packing and capable of passing over the upper part of the neck of
the bottle as heretofore. The cap has fixed thereto two or more spring catches
preferably bevelled on their undersides and square on their upper sides.
These catches are formed on or fixed to the free ends of springs, preferably made
of flat wire, lying close to and around a portion of the cylindrical part of the cap
and fixed to the latter so that the spring catches may be capable of moving
outwards when required.
Slots or openings are made in the cylindrical portion of the cap to permit of the
spring catches passing through the same and stops are sometimes fixed to the
outside of the cap to prevent the catches being opened out too wide.
11
I use the above improved stopper with a bottle, jar or other hollow article formed
with a conical end to the neck thereof and with a flange or groove on the neck so
as to enable the stopper to be fixed in position thereon by pressing the said stopper
thereon until the spring catches pass under the flange or into the groove in the neck.
The stopper is removed by opening-out and thereby relieving one or more of the
spring catches from the groove or flange.

the said Nathan Thompson in the Great Seal Patent Office on the 29th March
1883.
NATHAN THOMPSON of Brooklyn in the County of Kings and State of New York
in the United States of America but at present of 23 Southampton Buildings in
the County of Middlesex IMPROVEMENTS IN STOPPERS FOR BOTTLES JARS AND
OTHER HOLLOW ARTICLES
"
"
The Invention has for its object improvements in stoppers for bottles jars and
other hollow articles whereby the stopper is readily locked in position on the bottle
neck and released therefrom whilst a neat compact and efficient arrangement is
obtained.
For this purpose I form the body of the stopper of hollow cap lined or fitted
with cork or other suitable packing and capable of passing over the upper part of
the neck of the bottle as heretofore. The cap has fixed thereto two or more spring
catches preferably bevelled on their undersides and square on their upper sides.
These catches are formed on or fixed to the free ends of springs lying close to and
around a portion of the cylindrical part of the cap and fixed to the latter so that
the spring catches may be capable of moving outwards when required.
Slots or openings are made in the cylindrical portion of the cap to permit of the
spring catches passing through the same and stops are sometimes fixed to the
outside of the cap to prevent the catches being opened out too wide.
I use the above improved stopper with a bottle, jar or other hollow article formed
with a conical end to the neck thereof and with a flange or groove around the neck
so as to enable the stopper to be fixed in position thereon by pressing the said
stopper thereon until the spring catches pass under the flange or into the groove
around the neck. The stopper is removed by opening out and thereby relieving
one or more of the spring catches from the groove or flange.
And in order that my said Invention may be more clearly understood and
readily carried into effect I will proceed aided by the accompanying drawings
more fully to describe the same.

page_text: the spring catches c, passing through the same and stops a² are by preference
formed on the cap a. or fixed to the outside thereof to prevent the catches c. being
opened out too far.
The catches c and their springs c', are as shewn in the Drawing made of one piece
of sheet steel or other metal stamped and shaped to the required form; they may
however be formed of flat steel or other wire.
The stops a², as shown in the drawing are formed by the piece of metal separating
the two adjacent slots al such part being caused to project a short distance from
the cylindrical part of the stopper a, to permit of the required motion of the
catches c, a single alot or hole a', may however be formed in each side of the
cylindrical part of the cap a in which case the stop a², would consist of a wire or
piece of metal fixed across the centre of such slot or hole a'.
I use the above improved stopper with a bottle, jar or other hollow article d,
formed with a conical end d¹ to the neck thereof and with a flange or with a
groove d, around the neck so as to enable the stopper to be fixed in position by
pressing it thereon, which action causes the spring catches c, (by their inclined
undersides coming against the conical end of the bottle neck) to be forced
outwards until they pass under the flange or into the groove d², around the neck of
the bottle.
The stopper is removed from the bottle neck by opening out and thereby
relieving one or more of the spring catches c, from the groove d², or from underneath
the flange around the bottle neck.
In applying my Invention to large stoppers I fix thereto three spring catches c,
in which case the stopper can be fixed in position in the manner above described
whilst it can be removed by opening out two of such spring catches c, andstilting
the stopper.
Having thus described the nature of my said Invention and the mode in which
I carry the same into effect I would have it understood that I do not claim
generally the application of spring catches to a cap or stopper for securing the same
in position on the article to which it is applied as spring catches of various forms
have heretofore been applied to stoppers but what I do claim is the construction of
stoppers with slots a', stops a², and spring catches c constructed, applied and
operating in manner substantially as herein shown and described.
In witness whereof I the said Nathan Thompson have hereunto set my hand
and seal this twenty Eighth day of March in the year of Our Lord one
thousand eight hundred and eighty three.
