page_text: LETTERS PATENT to Hiram Codd, of No. 58, King William Street, in the
City of London, for an Invention of 'IMPROVEMENTS IN GLASS BOTTLES
16
AND IN MOULDS USED IN THE MANUFACTURE OF SUCH BOTTLES!"
PROVISIONAL SPECIFICATION left by the said Hiram Codd at the Office
of the Commissioners of Patents on the 19th September 1881.
HIRAM CODD, of No. 58, King William Street, in the City of London.
"IMPROVEMENTS IN GLASS BOTTLES AND IN MOULDS USED IN THE MANU-
FACTURE OF SUCH BOTTLES."
At the present time bottles for containing beer and other liquids are sometimes
made to be closed by caps or plugs screwed on to or in to a screw thread formed
around the exterior or interior of the heads. The stoppers frequently get lost by
reason of there being no part of the bottle to which the screw caps or plugs can be
connected when the bottle is opened. To avoid this I form either a projection
from one side of the bottle, or a cylindrical recess into the side of the bottle, with
a screw thread around its exterior or interior on to or in to which the cap or screw
plug can be at once screwed when taken off from the head; the cap or plug can in
this way always be kept connected with its own bottle. The above mentioned
projection or recess I am able to form by employing a mould, made as herein after
described, for shaping the bottle at the time when it is being blown.
It is also frequently desired to affix metallic labels to the sides of glass bottles,
but at the present time there is no way in which this can conveniently be done.
Now by the use of a mould made according to my Invention I am enabled to
form at the side of a bottle a flattened recessed surface of any desired height,
leaving the rounded side of the bottle above and below to project outwards beyond
it. The edge of glass so projecting outwards beyond the flattened surface I can
also make somewhat V shaped or rounded in place of straight. I can also make
the edges to somewhat overlap the flattened surface, so that the edge of a metal
plate may enter and be held between them. In this way a metal plate of the size
of the flattened surface, and cut at its ends to correspond to the V shaped or
Duins C71

page_text: rounded projecting edges of glass before mentioned, may when somewhat bent be
placed over the flattened surface, and be then straightened by pressure applied to
it; the top and bottom ends of the plate will then pass below the overlapping edge
before mentioned; and the plate cannot then slide out in any direction, and can
only be removed by again bending the metal plate, which could only be done
intentionally.
To form bottles in the above manner I form the moulds as heretofore, divided
by a vertical division into two equal parts, and hinged together at the bottom and
at the edges of the two parts of the mould, where they meet together when closed.
I form either recesses or projections of the form necessary either to mould a pro-
jection on the exterior of the bottle or a recess in it, as above explained, one half
of the recess or projection being moulded at the edge of one part of the mould, and
the other at the edge of the other part of the mould, so that when a bottle has
been blown into the mould the mould, can be opened in the ordinary manner by
one part turning downwards on the hinge joint at the bottom of the mould.
When a recess with a screw thread around it is to be formed into the side of, a
bottle, I form a hole through the side of the mould where the two parts meet
together through this I pass a screw stem of the 'required diameter. The end of
this screw projects into the interior of the mould when the mould is closed, and
produces a recess in the side of any bottle formed in it.
On the outer end of the screw stem I fix a pinion to gear with a sliding rack on
ane of the parts of the mould, and by means of a lever I move the rack endwise
and revolve the pinion so as to turn the screw stem and screw it out from the
recess in the bottle before the bottle, is removed from the mould.
Other forms than those herein before mentioned can in like manner be moulded
at the sides of bottles according to the shape given to the abutting edges of the
two parts of the mould.

At the present time bottles for containing beer and other liquids are sometimes.
I made to be closed, by caps or plugs screwed on to or in to a screw thread formed
around the exterior or interior of the heads. The stoppers frequently get lost by
0 reason of there being no part of the bottle to which the screw.caps or plugs can
be connected when the bottle is opened. To avoid this I form either a projection
from one side of the bottle,, or a cylindrical recess into the side of the bottle, with
ra a screw thread around its exterior or interior on to or into which the cap or screw
plug can be at once screwed when taken off from the head; the cap or plug can in.

It is also frequently desired to affix metallic labels to the sides of glass bottles,
but at the present time there is no way in which this can conveniently be done.
T
Now by the use of a mould made according to my Invention I am enabled to
form at the side of a bottle a flattened recessed surface of any desired height
leaving the rounded side of the bottle above and below to project outwards beyond
it. The edge of glass so projecting outwards beyond the flattened surface I can}
also make somewhat V shaped or rounded in place of straight. I can also. make.
5 the edges to somewhat overlap the flattened surface, so that the edge of a metal
plate may enter and be held between them. In this way a metal plate of the size :
of the flattened surface, and cut at its ends to correspond to the V shaped or:
rounded projecting edges of glass before mentioned, may when some what bent bec
placed over the flattened surface, and be then straightened by pressure applied to:
0 it; the top and bottom ends of the plate will then pass below the overlapping-edge
before mentioned, and the plate cannot then slide out in any direction, and can
only be removed by again bending the metal plate, which could only be done
intentionally.
.
To form bottles in the above manner I form the moulds as heretofore, divided.
5 by a vertical division into two equal parts, and hinged together at the bottom
and at the edges of the two parts of the mould, where they meet together when>
closed. I form either recesses or projections of the form necessary either to mould
a projection on the exterior of the bottle or a recess in it, as above explained,
one half of the recess or projection being moulded at the edge of one part of the
0 mould, and the other at the edge of the other part of the mould, so that when
a bottle has been blown into the mould the mould can be opened in the ordinary,
manner by one part turning downwards on the hinge joint at the bottom of the
mould.
When a recess with a screw thread around it is to be formed into the side of a
5 bottle, I form a hole through the side of the mould where the two parts meet
together; through this I pass a screw stem of the required diameter.
The end of this screw projects into the interior of the mould when the mould is
closed, and produces a recess on the side of any bottle formed in it.
On the outer end of the screw stem I fix a pinion to gear with a sliding rack on
0 one of the parts of the mould, and by means of a lever I move the rack end wise
and revolve the pinion so as to turn the screw stem and screw it out from the
recess in the bottle before the bottle is removed from the mould.
Other forms than those herein before mentioned can in like manner be moulded
at the sides of bottles according to the shape given to the abutting edges of the
5 'two parts of the mould.

page_text: In the Drawing hereunto annexed I have shewn examples of bottles formed as
above described, and also moulds. for making such bottles.
Figure 1 shews a side view of a bottle closed by a screw stopper screwing into
the interior of the head of the bottle; this bottle is formed with an internal pro-
jection a, which is hollow, and has a screw thread formed around its interior for
the screw portion of the screw stopper to be screwed into when the bottle has been
opened; the dotted lines b shew the stopper thus screwed into this recess a. The
bottle is also formed with a flattened surface c at its side, over which a label can
be secured by V shaped overhanging parts d, as above described.
A face view of this flattened surface is seen in the side view of the bottle shewn
at Figure 2:
Figure 3 shews a side view of a bottle formed with an external projection a,
with a screw thread around its exterior for a screw cap used for closing the bottle
to screw on to when the bottle is opened, as shewn by the dotted lines b.
Figure 4 shews à longitudinal section of a mould suitable for forming the bottle
shewn at Figures 1 and 2; and Figure 5 shews a similar view of a mould suitable
for forming the bottle shewn at Figure 3; Figure 6 shows another longitudinal
section of this mould taken.at right angles to the section, Figure 5; and Figure 7
is a cross section of the mould.
The mould shewn at Figures 5, 6, and 7 is an ordinary glass worker's mould for.
bottle making, except that the side edges of the two parts where they meet together
are made on the one side. with projections e for shaping the flattened surface, and
on the other with recesses f for moulding the screw projection a
'
The mould shewn at Figure 4 is of the same construction, except that, instead of
the recessed parts f, it is provided with a stem g. having a screw thread on its end
for forming the internal projection a of the bottle, Figure 1.
When a bottle has been made in a mould: formed as shewn at Figure 4, the
stem g. has to be unscrewed from the recess a in the bottle before the bottle can be:
removed from the mould. Any convenient mechanical arrangement may be adopted
for turning the screw stem to unscrew it. In the Drawing it is shewn to have
upon it a toothed pinion, into which gears a toothed rack h, so that by moving this
rack end wise a revolving motion may be given to the screw stem. When' the screw
stem has thus been unscrewed from the bottle, the mould can be opened and the
bottle removed in the ordinary manner.-"
I
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that I claim,
First: The manufacture of glass bottles that are to be closed by screw stoppers'
or caps with an internal or external screw projection' at their side for the screw
stopper or capito screw in or on to when the bottle has been opened.
Second: The manufacture of glass bottles with a flat surface at their side for a
metallic or other label to be placed over, and witli the exterior of the sides of the
bottle above and below such flat surface formed in the manner herein before
described to retain such label-in place.
Third The construction of moulds for making glass bottles, substantially as
herein before described, to enable projections or recesses to be formed at the sides
of the bottles.
In witness whereof; I, the said Hiram Codd; have hereunto set my hand and
seal, this Seventeenth day of March, in the year of our Lord. One thousand
