We, DANIEL WILLIAM BLAXTER, of 60, Lincoln's Inn Fields, in the County of
Middlesex, Engineer, and SOLOMON GREAVES PAGE, of 26, Baring Street, New
North Road, Hoxton, in the County of Middlesex, Engineer, do hereby declare the
nature of our invention for IMPROVEMENTS IN SCREW NECK BOTTLES AND STOPPERS,
FOR SAME; HAVING JOINTS MADE OF CORK to be as follows:-
:
The object of our invention is to produce a bottle and stopper of which the
contents can be perfectly secured and released without coming into contact with
any other substance than porcelain, glass, and cork, thus dispensing with the
deleterious substances such as vulcanite, india-rubber, and other compositions,
hitherto used in this class of bottles.
'
To accomplish this, we, in the first place, form the neck of a bottle with an
internal screw thread, and with a seating having two cones intersected with a slight
hollow, below the said thread.
Secondly, we construct a stopper of hard wood or porcelain, having a complete
or segment thread of the same pitch as that in the neck of the bottle, the stopper
being hollow at its base and having an internal left-handed screw thread in the
said hollow; into this hollow we fit a left-handed porcelain or glass set-screw, thus
securely fixing a hollow cork between the head of the said set-screw and the base
of the main stopper.. Our object in having the threads of a contra traverse is to
ensure that the loosening of one shall tend to the tightening of the other, so that
when unscrewing the main stopper to empty the bottle, should any glutenous
substance adhere to the cork, the set-screw tightens upon the said cork, thus firmly
securing it to the main stopper instead of leaving it in the neck of the bottle, as
otherwise it would be left.
Having thus stated the particulars of our invention, what we claim is :-
Firstly, a bottle with an internal screw neck having a seating constructed of two
cones intersected with a slight hollow, below the thread.
Secondly, a stopper having a complete or segment right-handed thread and a
hollow base, internally screwed with a left-handed thread in which is fitted a
porcelain or glass set-screw fixing a hollow cork between the head of the said set-
screw and. the base of the main stopper; the whole being so arranged as to enable
anyone to replace the corks as required.

having Joints made of Cork.
We, DANIEL WILLIAM BLAXTER of 60 Lincoln's Inn Fields in the County of
Middlesex, Engineer, and SOLOMON GREAVES PAGE of 26 Baring Street, New
North Road, Hoxton, in the County of Middlesex, Engineer, do hereby declare the
nature of our invention for IMPROVEMENTS IN SCREW-NECK BOTTLES AND STOPPERS
FOR SAME HAVING JOINTS MADE OF CORK, to be as follows:-
The object of our invention is to produce a bottle and stopper of which the
contents can be perfectly secured and released without coming into contact with
any other substance than porcelain, glass and cork, and thus dispensing with the
deleterious substances such as vulcanite, india-rubber, and other compositions
hitherto used in this class of bottles.
To accomplish this, we, in the first place, form the neck of a bottle, (Figure 1 in
accompanying drawings) with an internal screw thread, and with a seating having
two cones intersected with a slight hollow (a in Figure 1) below the said thread.
Secondly we construct a stopper of hardwood or porcelain or other suitable
material of which Figure 4 is the plan of the top, Figure 5 the plan of the base,
Figure 6 the elevation, and Figure 7 a sectional elevation. This stopper has a
complete or segment thread of the same pitch as that in the neck of the bottle, is
hollow at its base, (b in Figure 7), and has an internal left-handed screw-thread in
the said hollow. Into this hollow we fit a left-handed porcelain or glass set-screw
of which Figure 11 is the plan and Figure 10 is the sectional elevation (shewing
hollow cork (c) attached), and thus securely fix a hollow cork (of which Figure 8 is
the plan and Figure 9 the elevation) between the said set-screw and the base of
the main stopper. Our object in having the threads of contra-traverse is to insure
that, the loosening of one shall tend to the tightening of the other, so that when
the main stopper is unscrewed to empty the bottle, should any glutenous substance
adhere to the cork, the set-screw tightens upon the said cork thus firmly securing
it to the main stopper instead of leaving it in the neck of the bottle as otherwise
it would be left.
The manner in which we make our segment thread is by fitting core-prints in
the mould used in forming the main stopper. These core-prints bore a hole through
the said stopper at an angle corresponding to the thread in the neck of the bottle.
Figure 3 shows the plan, and Figure 2 the end elevation of this hole. We then
place the stopper in a screwed mould and, by pouring molten metal or other suitable
substance into the hole, make the segment thread on the outside of the body of the
main stopper (d in Figure 7).
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
(1.) A bottle with an internal screw neck having a seating (below the thread)
constructed of two cones intersected with a slight hollow.

page_text: (2.) A stopper having a complete or segment right-handed thread and a hollow
base internally screwed with a left-handed thread in which is fitted a porcelain or
glass set-screw fixing a hollow cork between the head of the said set-screw and the
base of the main stopper, the whole being so arranged as to enable anyone to
replace the corks as required.
(3.) A segment thread made and formed in the manner heretofore described.
