Improvements in the Manufacture of Stoppers for Bottles and other
like Receptacles.
We, FORDER BREWER STANLEY of 10 Cassland Road, South Hackney in the
County of London, Engineer, and CHARLES STUART MOORE of 20 Cheyue
Court, Chelsea in the same County Civil Engineer, do hereby declare the nature
of this invention to be as follows:-
This invention consists of improvements in the manufacture of stoppers for
bottles and other like receptacles and has reference more particularly to scrow and
other stoppers which are moulded under pressure to the desired shape or form from
a suitable material or composition such for example as lionite, woodite, herculite,
vulcanite and the like.
The objects we have in view are to give a more ornamental or decorative
appearance to the top or upper portion of the stoppers, and to enable any desired
characters or dovice such for example as a firm's name, a trade mark or the like to
be stamped, printed or otherwise produced or shown thereon either in any required
color or plain which cannot be done with useful or permanent effect in the case of
stoppers as ordinarily made from lionite, woodito, herculite, or the like.
The invention consists primarily in applying to the top and preferably also to
the milled or other edge of the upper part of the stopper in the course of
manufacture a thin layer or coating of xylonite, celluloid or other pyroxyline
compound, and this we effect by placing a thin layer or strip of xylonite, celluloid
or pyroxyline compound of any required color or colors in the part of the mould
which corresponds with the top or upper part of the stopper; we then fill the
mould with the material or composition from which it is to be made and submit the
material to pressure in the usual way. During this moulding or pressing operation
the pyroxyline compound becomes perfectly united to the material or composition so
as to constituto a permanent face to the top or upper part of the stopper. If found
necessary a little solvent may be used with the xylonite or pyroxyline compound
or this compound may be softened before being put into the mould.
This xylonite face is capable of receiving any desired impression in any desired
color or colors by stamping or otherwise; trade marks or other devices or
characters can therefore be produced thereon in a perfectly distinct and clear
manner. Or devices may be produced on the xylonite face during the moulding
operation if the mould bears the counterpart of such devices. Or according to
another method we introduce a paper or other label or ticket bearing the desired
device between the pyroxyline compound and the composition in the mould before
the moulding operation so that it becomes fixed between them. As the pyroxyline
compound can be of a transparent character the label can be distinctly seen through
it while it is perfectly protected.
According to another method which we employ when using a paper or other
label or ticket between the composition and the pyroxyline compound as above
described, we first mould the stopper from lionite or other composition in any
ordinary way but with a recess in the top. Then we put the label or ticket into
this recess and over the label a piece of transparent pyroxyline compound. We
next place the stopper with the label and pyroxyliue compound into a heated
mould which softens the pyroxyline and the head of the stopper.
We then submit the whole to pressure whereby the pyroxyline and the
composition of the stopper become firmly united at and near the edges of the
former. In this last method we cau employ tale or mica in lieu of the pyroxyline

page_text: compound; the edges of the talc and mica become embedded in or united to the
head of the stopper the material of which is compressed or forced around them.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Stoppers for Bottles and other
like Receptacles.
We Forder_Brewer Stanley of 10 Cassland Road, South Hackney in the
County of London, Engineer, and CHARLES STUART MOORE of 20 Cheyne
Court, Chelsea in the same County, Civil Engineer, 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 consists of improvements in the manufacture of stoppers for
bottles and other like receptacles and has reference more particularly to screw
and other stoppers which are moulded under pressure to the desired shape or form
from a suitable material or composition such for example as lionite, woodite,
herculite, vulcanite and the liko.
The objects we have in view are to give a more ornamental or decorative
appearance to the top or upper portion of the stoppers, and to enable any desired
characters or device, such for example as a firm's name, a trade mark or the like,
to be stamped, printed or otherwise produced or shown thereon either in any
required color or plain, which cannot be done with useful or permanent effort
in the case of stoppers as ordinarily made from liouite, woodite, herculite or tho
like.
The invention consists primarily in applying to the top and preferably also to
the milled or other edge of the upper part of the stopper in the course of many-
facture, a thin layer or coating of xylonite, celluloid or other pyroxyline compound,
and this we effect by placing a thin layer or piece of xylouite, celluloid or pyro-
xyline compound of any required color or colors in the part of the mould which
corresponds with the top or upper part of the stopper; we then fill the mould with
the material or composition from which it is to be made and submit the material
to pressure in the usual way. During this moulding or pressing operation the
pyroxyline compound becomes perfectly united to the material or composition so
as to constitute a permanent face to the top or upper part of the stopper.
found necessary a little solvent may be used with the xylonite or pyroxyline
compound; or this compound may be softened before being put into the mould.
If
This xylonite face is capable of receiving any desired impression in any desired
color or colors by stamping or otherwise; trade marks or other devices or
characters can therefore be produced thereon in a perfectly distinct and clear
manner. Or devices may be produced on the xylonite face during the moulding
operation if the mould bears the counterpart of such devices.
Or according to another method we introduce a paper or other label or ticket
bearing the desired device between tho pyroxyline compound and the material or
composition in the mould before the moulding operation so that by such operation
it becomes fixed between them. The pyroxyline compound in this case is of a
transparent charactor so that the label will be distinctly visible through it and will
at the same time be perfectly protected.
According to another method which we employ when using a paper or other
label or ticket between the composition and the pyroxyline compound as above
described, we first mould the stopper from lionite or other composition or material
in any ordinary way but with a circular or other recess in the top. Then we put
the label or ticket into this recess which may be slightly undercut or dovetailed
and over the label a piece of transparent pyroxyline compound. We next" place

page_text: the stopper with the label and pyroxyline compound into a heated mould which
softens the pyroxyline and the head of the stopper. We then submit the whole to
pressure whereby the pyroxyline and the material or composition of the stopper
become firmly united at and near the edge of the former. In this last method we
can employ a piece of talc or mica in lieu of the pyroxyline compound; the edge
of the talo or mica becomes embedded in or united to the head of the stopper, the
material of which is compressed or forced around them; for the sake of greater
economy the piece of talc, mica or pyroxyline compound may he dispensed with,
in which case the edge of the paper or other label or ticket placed in the recess in
the top of the stopper will become embedded in and united to the stopper when
the pressure is applied as hereinbefore described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed wo declaro that what we
claim is :-
1. In the manufacture of moulded stoppers for bottles and other like receptacles,
placing a layer or strip of xylonite or other pyroxyline compound in that part of
the mould which corresponds with the top or upper part of the stopper to be
produced, and filling tho mould with the material from which the stopper is to be
made and then submitting the material to the pressure required to mould the
stopper, whereby the pyroxyline compound becomes united to the material of the
moulded stopper so as to constitute a permanent face to the top or upper part of
same, substantially as and for the purpose hereinbefore described.
2. The modification of the manner of manufacture referred to in Claim 1 in
which a paper or other label or ticket is introduced between a transparent layer or
piece of pyroxyline compound and the material in the mould before the moulding
operation so that by this operation the label or ticket becomes fixed between them
and is visible through the pyroxyline compound as set forth.
3. In the manufacture of moulded stoppers for bottles and other like receptacles,
first moulding a stopper with a recess in the top, then insorting into this recess a
label or ticket and over this a piece of transparent pyroxyline compound or of
mica or talc, then placing the stopper into a heated mould and finally submitting
it to pressure whereby the pyroxyline compound, mica or talo and the material of
the stopper become united at and near the edge of the former, substantially as and
for the purpose hereinbefore described.
4. In the manufacture of moulded stoppers for bottles or other like receptacles,
first moulding a stopper with a recess in the top, then inserting a label or ticket
into this recess, then placing the stopper into a heated mould, and finally sub-
mitting it to pressure, whereby the label or ticket and the material of the stopper
become united at and near the edge of the former, substantially as and for the
purpose hereinbefore described.
