We, JOHN WILLIAM COLTMAN, of 17, Bold Street, Bradford, in the County
of York, Brush Maker, and WILLIAM HENRY CHANTER, of 43, Seymour Street,
Bradford, aforesaid, Brush Maker, do hereby declare the nature of this invention
to be as follows :—
This invention relates to improvements in screw-stoppers for beer and other
bottles; and its object is to enable the bottle neck to be more readily cleaned
and also to prevent dust and dirt accumulating between the rim of the bottle neck
and the stopper.
To carry out our invention we form an external screw thread round the top of
the bottle neck and we provide a flange, shoulder or collar below to form a seat for
an india-rubber or other suitable washer. The stopper consists of a cap having a
female screw thread to fit the screw thread on the bottle and is adapted to be
screwed upon the neck down onto the said washer to close the bottle.

We, JOHN WILLIAM COLTMAN, of 17, Bold Street, Bradford, in the County
of York, Brush Maker, and WILLIAM HENRY CHANTER, of 43, Seymour Street,
Bradford, aforesaid, Brush Maker, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to improvements in screw-stoppers for beer and other
bottles; and its object is to enable the bottle neck to be more readily cleaned and
also to prevent dust and dirt accumulating between the rim of the bottle neck and
the stopper.
To carry out our invention we form an external screw thread round the top of the
bottle neck and we provide a flange, shoulder or collar below to form a seat for an
india-rubber or other suitable washer. The stopper consists of a cap having a
female screw thread to fit the screw thread on the bottle and is adapted to be screwed
upon the neck down onto the said washer to close the bottle.
Reference is to be had to the accompanying sheet of drawings forming a part of
this specification, in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents an elevation of a bottle fitted with our improved stopper.
Figure 2, represents a similar view of the neck with the stopper in section.
Figures 3, 4 and 5 respectively represent an elevation, a diametrical section and
a plan view of the stopper alone.

page_text: Figure 6, represents a diametrical section of the said washer and Figure,
represents a plan of the same.
The bottle neck A has an external collar or shoulder B formed around it to form
a seat for the washer C and the diameter of the neck is preferably reduced inside the
washer so as to form an annular groove in which the washer lies.
The portion of the neck above the washer C is formed with a male or external
screw thread D and the cap or stopper E has a female screw thread F inside which
fits the screw thread D. When the cap E is screwed upon D the rim G of the cap
bears upon the washer and forms a tight joint.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
A bottle having a male screw outside the bottle neck, a flange or collar beneath
said male screw adapted to support a washer in combination with a cap or
hollow stopper having a female screw thread to fit the screw on the bottle
neck and a rim adapted to bear upon said washer, substantially as herein shown
and described.
Deted this 24th day of August 1896.
