IMPROVEMENTS IN MAKING GLASS BOTTLES AND IN THE APPARATUS CONNECTED THEREWITH
Year: 1859

page_text: LETTERS PATENT to Alexander Mein, Glass Bottle Maker, at Saint
Rollox, Glasgow, in the County of Lanark, for the Invention of
"IMPROVEMENTS IN MAKING GLASS BOTTLES AND IN THE APPARATUS
CONNECTED THEREWITH."
Sealed the 5th August 1859, and dated the 17th March 1859.
PROVISIONAL SPECIFICATION left by the said Alexander Mein at the
Office of the Commissioners of Patents, with his Petition, on the
17th March 1859.
I, ALEXANDER MEIN, Glass Bottle Maker, at Saint Rollox, Glasgow, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN MAKING
GLASS BOTTLES AND IN THE APPARATUS CONNECTED THEREWITH," to be as
follows:
I use a mould which is internally of the figure of the bottles to be made: it
is split vertically, so as to be capable of being opened into two halves; the
part which moulds the neck and rim of the bottle points vertically downwards,
and contains a hollow core spindle or nozzle to mould the tube of the neck
internally; the mould has also a cover which moulds the bottom of the bottle.
The mould-being shut laterally, but with the cover off; a proper quantity of
glass in a soft state is placed in it; the cover is then put on by hand or by
mechanism, a blast of air is blown by suitable apparatus through the hollow
spindle. this swells out the soft glass so as to make it fit the mould, and com-

by hand or by mechanism, and the bottle is taken out. The neck part of the
mould must point vertically downwards while the glass is put in and blown,
but during other parts of the process the mould may be turned into other
positions if convenient.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alexander Mein in the Great Seal Patent Office on the
10th September 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME. I. ALEXANDER
MEIN, Glass Bottle Maker, at Saint Rollox, Glasgow, in the County of
Lanark, send greeting.
WHEREAS ller most Excellent Majesty Queen Victoria, by Iler. Letters
Patent, bearing date the Seventeenth day of March, Eighteen hundred and
fifty-nine, in the twenty-second year of ller reign, did, for Herself, Iler heirs
and successors, give and grant unto me. the said Alexander. Mein. Her special
license that I, the said Alexander Mein, my executors, administrators, and
assigns, or such others as I and my foresaids should at any time agree with, and
no others, from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN MAKING GLASS BOTTLES, AND IN
THE APPARATUS CONNECTED THEREWITH," upon the condition (amongst others) that
I, the said Alexander Mein, by an instrument in writing under my hand
and seal, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alexander Mein, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol-
lowing statement, that is to say:-
I use a mould which is internally of the figure of the bottles to be made:
it is split vertically, so as to be capable of being opened into two halves; the
part which moulds the neck and rim of the bottle points vertically downwards,

page_text: and contains a hollow core, spindle, or nozzle to mould the tube of the neck
internally the mould has also a cover which moulds the bottom of the bottle.
The mould being shut laterally, but with the cover off. a proper quantity of
glass in a soft state is placed in it, the cover is then put on by hand or by
mechanism, a blast of air is blown by suitable apparatus through the hollow
spindle this swells out the soft glass so as to make it fit the mould, and
completes the formation of the bottle. The mould is then uncovered and
opened by hand or by mechanism, and the bottle is taken out. The neck
part of the mould must point vertically downwards while the glass is put in
and blown; but during other parts of the process the mould may be turned
into other positions if convenient.
One form of my apparatus is represented in the accompanying Drawing.
Figure is a side view of the apparatus: Figure 2 is a front view of the
apparatus with the cover lifted, and the front half of the mould removed, so as
to shew the internal figure of the mould distinctly. In Figure 1, the full lines
shew the mould shut laterally, and with the cover on, and its internal figure is
shewn by dotted lines. The position of the cover when lifted, and of the front
half of the mould when open, are also shewn by dotted lines. In both Figures
the same parts are denoted by the same letters.
A, A, is part of the stand or frame; B is the projecting bracket, base, or
platform of the backward half of the mould; C is the blast pipe bringing air
from any convenient blowing apparatus to the hollow core, spindle, or nozzle D,
which points upwards in the interior of the neck of the mould; E, E, is the
backward half the mould; F is the base of the front half of the mould
hinged to B, B, and G, G, is the front half of the mould itself. The capital
letters and G, G, indicate the position of those parts when the mould is shut
laterally; the small letters f and g. g. indicate the position of the same parts
when the mould is opened laterally, by the front half turning on the hinge
which connects F with B. A lever for moving the front half of the mould is
marked H when the mould is open, h when it is shut; K and are the
corresponding positions of part of a rod for moving that lever; I use a treadle
to move that rod. The front half of the mould might be moved by any other
convenient mechanism: L shews the cover of the mould when lowered; 1, the
position of the same cover when lifted: M and m shew the corresponding
positions of part of a lever for lifting and lowering the cover.
At present I use iron as the material of the apparatus, but other materials
might be used.
I do not bind myself to the details of the mechanism, which may be varied

page_text: according to convenience; nor do I claim separately the ordinary mechanical
parts of the apparatus described, but I do claim,-
First, the improved apparatus for moulding glass bottles, as herein-before
described.
Secondly, the making glass bottles by the aid of that apparatus, as herein-
before described.
In witness, whereof, 'I, the said Alexander Mein, have hereto set my
hand and seal, this Eighth day of September, in the year of our Lord
One thousand eight hundred and fifty-nine.
