I SAMUEL SKERRITT of 181 Devonshire Street Sheffield Yorkshire Ornamental
Iron Worker do hereby declare the nature of my said Invention for "IMPROVE-
MENTS IN THE MEANS AND APPARATUS FOR STOPPERING BOTTLES " to be as
follows:-
This Invention consists in the construction of a bottle the mouth of which is set
down from, or smaller in diameter than, the neck thereof and formed with an
external quick threaded screw, in combination with a cap with an internal screw
corresponding to the external screw on the mouth of the bottle; to the top of tho
said cap is fitted or fixed an elastic pad. By preference the pad is of india-rubber
and in the form of a half globe, and is retained in the cap by being inserted in a
recess therein.
When the cap is screwed onto the mouth of the bottle the elastic pad will be
compressed onto the bottle thus making a water-tight and gas-tight joint and the
outside of the cap will be flush with or even with the neck of the bottle.

page_text: COMPLETE SPECIFICATION,
I, SAMUEL SKERRITT of 181 Devonshire Street Sheffield in the County of York
Ornamental Iron Worker, do hereby declare the nature of my Invention for
IMPROVEMENTS IN THE MEANS AND APPARATUS FOR STOPPERING BOTTLES, and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
This Invention consists in the construction of a bottle the mouth of which is set
down from, or smaller in diameter than, the neck thereof, and formed with an
external quick threaded screw, in combination with a. cap with an internal screw
corresponding to the external screw on the mouth of the bottle; to the top of
the said cap is fitted or fixed an elastic pad. By preference the pad is of India
rubber and in the form of a half globe, and is retained in the cap by being inserted
in a recess therein.
When the cap is screwed on to the mouth of the bottle the elastic pad will bo
compressed on to the bottle, thus making.a water tight and gas tight joint and the
outside of the Cap will be flush with or even with the neck of the bottle.
The object of my invention is to improve the means of stoppering bottles
containing liquids or fluids under pressure, or otherwise; by constructing the bottle
with an external screw on the neck and constructing a cap or stopper with an
internal screw corresponding in pitch and depth to the said screw on the neck of
the bottle, such cap or stopper being fitted with an elastic pad which is pressed
down on to, or into the mouth of the bottle when the said cap or stopper is
screwed down on to the neck of the bottle far enough for that purpose; Bottles
with caps or stoppers so constructed can easily be closed by hand so as to be
perfectly tight and thereby prevent the admission of Air into the bottle, and in the
like manner prevent the escape of the contents.
The opening or unstoppering of the bottle, can also easily be effected by hand,
without any other mechanical aid.
The caps or stoppers and the bottles can be made interchangeable with other
caps and bottles of the same construction, and the caps and stoppers can be used
over and over again without renewal, the accompanying sheet of Drawings
illustrate my invention in which
Fig 1 represents a bottle the neck or mouth of which is set down from or
smaller in diameter than the neck thereof and formed with an external quick
threaded screw A A.
Fig 2 represents a section of the Cap or stopper with an internal screw B B
corresponding to the external screw A A on the neck of the mouth of the bottle;
inside the top of the said cap is fitted or fixed an elastic pad C.
Fig 3 represents the same bottle and cap but with the cap screwed down on to
the neck of the bottle so as to press the elastic pad C, down on to or into the mouth
of the bottle as shewn by the dotted lines.

page_text: The caps or stoppers as herein described may be made of metallic or other
suitable substance, they may be left plain outside or may be ornamented, recessed
or milled, so as to enable a better grip being taken when screwing, or unscrewing,
in or out of the bottle.
Glass is the material which by preference would be used in the manufacture and
construction of the bottles as herein described, and the thread or worm is formed
on the neck of the bottle after the said bottle has been blown or cast, by heating
the neck of the bottle to a sufficiently high temperature to enable the thread of the
screw or worm being formed by passing or turning the heated part between
dies or tools having corresponding threads of a worm or screw on their surface,
which form the screw on the neck of the bottle whilst the glass is in a heated and
pliant condition.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
•
1. Forming an external screw or worm on the necks of bottles made of Glass or
other material which can be worked and manipulated like glass such worm or
screw being of a less diameter than the neck, and being so formed on the neck after
the bottle is blown or cast, by heating the neck of the bottle to a sufficiently high
temperature to enable the thread of the screw or worm being formed thereon by
passing or turning the heated part between dies or tools having corresponding
threads of a worm or screw on their surface to form the screw on the neck of the
bottle.
2. Using in combination with the bottle made as last described a cap or stopper
made of metal wood or other equivalent material fitted with an elastic pad and
with an internal screw or worm corresponding to the external screw or worm on
the neck of the said bottle, such cap or stopper being used to stopper or close the
orifice or mouth of the bottle, substantially as herein described and set forth.
