for Containing Aerated Liquids.
We, WILLIAM WILSON MACVAY and RICHARD SYKES Bottle Manufacturers and
WILLIAM WAINWRIGHT Fitting shop Foreman all of the Albion Glass Works,
Castleford in the County of York, do hereby declare the nature of this invention
to be as follows:-
In bottles for containing aerated liquids the mouth of the bottle is commonly
stopped by a ball of glass or other stopper held by the pressure within the bottle up
to and against a ring of vulcanized india rubber held in a groove formed around the
interior of the mouth.
With such bottles much inconvenience is experienced by reason of the rings of
vulcanized india rubber being removed from the bottles.
To prevent the removal of the rings we make the groove in the bottle of a dovetail
form in cross section and to form such a groove around the mouth we form the pair
of dogs which are made to protrude from the central plug or core of the tool which
passes into and shapes the interior of the mouth in such a manner that one of them
serves to shape the upper side of the groove and the other the under side. Each
dog being thus smaller than the mouth of the groove can leave it readily.
We also make the tongs in such a manner that the dogs are moved in and out from
the core with a positive movement when the tongs are opened and closed-so that the
spring of the side arms of the tongs is made use of to withdraw the "dogs" when
the tongs are allowed to open and these being strong spring arms the withdrawal of
the dogs is ensured.
"
Each dog is at the end of a bar which at its opposite end is pivotted to the central
stem by which the "swiller plate" and "central core are carried. An arm extends
outwards from each bar and has a groove cut in it into which a pin fixed into one
or other arm of the tongs enters and the grooves are so shaped that when the tongs
are closed the dogs move out from the central core and when the tongs are opened
they are withdrawn into the core.

page_text: for Containing Aerated Liquids.
We, WILLIAM WILSON MACVAY, and RICHARD SYKES, Bottle Manufacturers, and
WILLIAM WAINWRIGHT, Fitting shop Foreman, all of the Albion Glass Works,
Castleford, in the County of York, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascertained
¡n and by the following statement :-
In bottles for containing aerated liquids the mouth of the bottle is commonly
stopped by a ball of glass or other stopper held by the pressure within the bottle up
to and against a ring of vulcanized india rubber held in a groove formed around the
interior of the mouth.
With such bottles much inconvenience is experienced by reason of the rings of
vulcanized india rubber being removed from the bottles.
To prevent the removal of the rings we make the groove in the bottle of a
dovetail form in cross section and to form such a groove around the mouth we
form the pair of dogs which are made to protrude from the central plug or core of
the tool which passes into and shapes the interior of the mouth in such a manner
that one of them serves to shape the upper side of the groove and the other the under
side. Each dog being thus smaller than the mouth of the groove can leave it
readily.
We also make the tongs in such a manner that the dogs are moved in and out from
the core with a positive movement when the tongs are opened and closed-so that the
spring of the side arms of the tongs is made use of to withdraw the "dogs" when
the tongs are allowed to open and these being strong spring arms the withdrawal of
the dogs is ensured.
Each dog is at the end of a bar which at its opposite end is pivotted to the central
stem by which the "swiller plate and :: central core are carried. An arm extends
outwards from each bar and has a groove cut in it into which a pin fixed into one or
other arm of the tongs enters and the grooves are so shaped that when the tongs are
closed the dogs move out from the central core and when the tongs are opened they
are withdrawn into the core.
We make no claim to the bottle, our invention relates only to the tools used for
forming it.
Figures 1 and 2 of the drawing annexed shew tongs formed in the above manner.
Figure 1 shews the tongs open and Figure 2 the tongs closed. Figure 3 is a
transverse section of the head of a bottle formed by such tongs.
A A are the spring arms of the tongs,B are the blocks carried at their end for
shaping the exterior of the head of a bottle-C is the central rod carrying at its end
the central core D and the swiller plate E-F1 F1 are the teeth or dogs which are
made to protrude from the central core when the tongs are closed.

page_text: Each dog F is at the end of a bar F which is pivotted at F2 to the central rod C-
F3 are arms extending outwards from each bar and having slots F' cut in them
through which are passed pins G carried by the arms A. The inner ends of the
slots are concentric with the centre about which each arm turns or bends and the
outer ends are inclined thereto so that when the pins G enter these parts of
the slots the bars must of necessity turn around their pivot F2-and the inner ends
of the grooves being concentric with the centre on which each arm turns the dogs
must be fully protruded before the tongs are fully closed so that the grooves in the
bottles are always made of the same depth.
Each dog as will be seen is smaller than the groove formed in the head of
the bottle and one shapes the upper side of the groove and the other the
lower side.
Other means than those shewn might be employed for protruding and with-
drawing dogs formed in this manner we prefer however to use the arrangement
shown.
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 :-
:-
1. Forming tools, used for moulding dovetail grooves in the mouths of bottles, with
one of the dogs which are made to protrude from its central core shaped to mould the
upper side only of the groove and the other to mould its under side only substantially
as described.
2. Forming tools used for moulding dovetail grooves in the mouths of bottles in
such manner that the dogs are by the spring of the side arms of the tongs moved in
and out from the central core with a positive movement when the tongs are opened
and closed.
3. The construction of tools used for moulding dovetail grooves in the mouths of
bottles substantially in the manner herein before described.
