IMPROVEMENTS IN THE MANUFACTURE OF GLASS BOTTLES
Year: 1882

page_text: LETTERS PATENT to James Scope Davison of Sunderland, in the County of
Durham, Glass Manufacturer for an Invention of IMPROVEMENTS IN THE
MANUFACTURE OF GLASS BOTTLES.
PROVISIONAL SPECIFICATION left by the said James Scope Davison at
the Office of the Commissioners of Patents on the 30th December 1882.
JAMES SCOPE DAVISON of Sunderland in the County of Durham, Glass
Manufacturer "IMPROVEMENTS IN THE MANUFACTURE OF GLASS BOTTLES,"
My invention relates to a process of manufacturing glass bottles, especially in
what is known as "black" or "dark" metal, in such a manner as to dispense with
the use of tools (or "shears ") and "finisher," known as the bottle maker, to form
the neck or mouth of the bottle.
To effect this I employ moulds, into which the bottle is to be blown, having the
particular formation of the neck and mouth formed in them, and by means of
which the bottle is finished at one operation by the blower, requiring only grinding
round the mouth.
The moulds I propose to use are formed so as to give to the neck and mouth of
the bottles, while being blown, the internal and external formation required
without using tools, as at present, after the bottle is blown.
The neck or mouth, or both, may be thus formed with one or more internal sunk
grooves or raised ribs, or a combination of both, either parallel to each other and
at a right angle or any other angle to the centre line of neck, or forming threads
of a screw, or of any other formation suitable for the stopper intended to be used,
the outside of the neck and mouth following the same formation of the interior.
The process of manufacture is as follows: The bottle being blown in the mould
the neck and mouth are at once formed of the required shape and the superfluous
metal being cut off, the bottle is taken to the annealing furnace and afterwards the
mouth is finished by grinding or other means.

page_text: In some of the various forms in which the neck and mouth may be made I
propose to employ elastic rings, hoops or washers, split or otherwise, which are
sprung into their place, but no such fitting is essential as the neck or mouth or
both, being formed as described may be closed by an ordinary cork or by any
other stopper made to suit the formation of the neck or mouth without any elastic
fitting.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said James Scope Davison in the Great Seal Patent Office on the
29th June 1883.
JAMES SCOPE DAVISON of Sunderland in the County of Durham Glass
Manufacturer IMPROVEMENTS IN THE MANUFACTURE OF GLASS BOTTLES
My invention relates to a process of manufacturing glass bottles, especially in
what is known as "black" or "dark" metal, in such a manner as to dispense with
the use of tools (or "shears ") and "finisher" known as the bottle maker to form
the neck or mouth of the bottle
To effect this I employ moulds, into which the bottle is to be blown, having the
particular formation of the neck and mouth formed in them, and by means of which
the bottle is finished at one operation by the blower requiring only grinding round
the mouth
The moulds I propose to use as to their general construction are similar to those
ordinarily in use, but the upper portion of the mould is formed so as to give to the
neck and mouth of the bottles, while being blown, the internal and external
formation required without using tools, as at present, after the bottle is blown,
The neck or mouth, or both, may be thus formed with one or more internal sunk
grooves, or raised ribs, or a combination of both, either paralell to each other and
at a right angle or any other angle to the centre line of neck, or forming threads of
a screw, or of any other formation suitable for the stopper intended to be used, the
outside of the neck and mouth, following the same formation of the interior. One
special form in which I propose to make these bottles is with a square mouth
(joining into a round neck) so as to receive a square cork which can be more
cheaply made than ordinary round corks. The process of manufacture is as
follows: The bottle being blown in the mould the neck and mouth are at once
formed of the required shape and the superfluous metal being cut off, the bottle is
taken to the annealing furnace and afterwards the mouth is finished by grinding
or other means. In some of the various forms in which the neck and mouth may
be made I propose to employ elastic rings, hoops, or washers, split or otherwise,
which are sprung into their place, but no such fitting is essential as the neck or
mouth or both, being formed as described, may be closed by an ordinary cork or by
any other stopper made to suit the formation of the neck or mouth without any
elastic fitting and any such fitting, except as applied to bottles made according to
my invention, I do not consider as forming part of my patent.

page_text: as to
I have not thought it necessary to shew by drawings how the bottles are made
as the novelty is not in any special tools but in so forming the moulds so
make the mouth or neck (or both) of the bottle, of any desired form for receiving
the stopper or cork, in the process of blowing dispensing with the after process of
finishing the mouth as at present required.
Having now fully described my invention and the objects to be attained I would
have it understood that what I claim as new and secured to me by Letters patent
hereinbefore recited is:
First. The manufacture of Glass bottles by blowing in moulds in such a manner
that the mouth is made to take any required formation to suit the stopper or cork
and is finished by the blower, without any subsequent process, except grinding,
substantially as described.
Second. The manufacture of bottles in the manner above described with square
mouths to receive square corks substantially as described
In witness whereof I the said James Scope Davison have hereunto set my
hand and seal this twenty eighth day of June in the year of our Lord
one thousand eight hundred and eighty three.
A
JAMES.
