AND APPARATUS OR TOOLS THEREFOR "
PROVISIONAL SPECIFICATION left by the said Thomas Pyke at the Office
of the Commissioners of Patents on the 22nd August 1882.
THOMAS PYKE, of South Shields, in the county of Durham,
"IMPROVEMENTS
IN THE MANUFACTURE OF GLASS BOTTLES AND APPARATUS OR TOOLS THEREFOR
"
This invention relates to an improved method of and apparatus or tool for
finishing the mouths of glass bottles.
By the present mode of finishing the mouths of glass bottles, the tendency of
the workman is to make the bottle neck thin, so that the ring or mouth may be
put on easily and as a consequence, if the ring is not worked on to the bottle neck
with sufficient care, the bottle has not a smooth mouth as a piece of metal or
"bite" is left inside which forms an obstruction in corking and uncorking often
resulting in the splitting of the neck of the bottle and the loss of the liquor.
According to my improvements the above named defects are obviated, greater
homogeneity is obtained by the neck of the bottle being formed of one piece from
the shoulder to the mouth, the inside of the mouth being uniformly smooth, and
considerably stronger than when made by the present method and the necessity of
employing skilled labour for finishing the bottle is dispensed with.
In carrying out my invention instead of the mouth of the bottle being worked
on and finished by shears as usual I form the mouth in the mould which is adapted
to form the neck with a ring or groove on its exterior, as may be required for
capsuling purposes.
The bottle being thus moulded the mouth is finished in a tool or machine
constructed as follows, videlicet :-
I employ a frame or stand provided with a plug similar to the plug of the
ordinary shears, this plug is either placed in the centre of a hollow bush in the stand
or may project from the stand and be surrounded with a metal ring or cylinder.
The mouth of the bottle is heated and placed on the hereinbefore described plug
and turned thereon by which operation the interior and exterior of the mouth of
the bottle will be smoothed and the openings of the mouths of the bottles will be
of uniform size and thickness and without the usual "bite" in the interior

This invention relates to an improved method of and apparatus or tool for
finishing the mouths of glass bottles."
"
By the present mode of finishing the mouths of glass bottles, the tendency of
the workman is to make the bottle neck thin, so that the ring or mouth may be
put on easily and, as a consequence, if the ring is not worked onto the bottle neck
with sufficient care, the bottle has not a smooth mouth, as a piece of metal or
bite" is left inside which forms an obstruction in corking and uncorking, often
resulting in the splitting of the neck of the bottle and the loss of the liquor.
According to my improvements the above named defects are obviated, greater
homogeneity is obtained by the neck of the bottle being formed of one piece from
the shoulder to the mouth, the inside of the mouth being uniformly smooth and
considerably stronger than when made by the present method and the necessity of
employing skilled labour for finishing the bottle is dispensed with.
In carrying out my invention instead of the mouth of the bottle being worked.
on and finished by shears as usual I form the mouth, in the mould which is
adapted to form the neck, with a ring or groove on its exterior, as may be
required for capsuling purposes.
The bottle being thus moulded, the mouth is finished in a tool or machine
constructed as follows, videlicet :-
I employ a frame or stand provided with a plug similar to the plug of the
ordinary shears; this plug is either placed in the centre of a hollow bush in the
stand or may project from the stand and be surrounded with a metal ring or
cylinder.
Or the cylinder may be formed in two parts or halves hinged or jointed together;
one part is fixed or formed on the stand and the other part works on the hinge or
joint and is operated by means of a treadle in such a manner as to allow of the
neck of the bottle being clasped by the cylinder when the mouth of the bottle is
passed over the plug.
In order to enable my invention to be better understood I will proceed to
describe the same by reference to the accompanying drawing in which figure 1, is
a front elevation and figure 2, a transverse section shewing a suitable construction
of tool or machine for finishing the mouths of glass bottles according to my
invention and in which the plug is placed in the centre of a hollow bush fitted in
the stand; figure 3, is a front elevation; figure 4, a side elevation and figure 5, a
section through the line A B of figure 3, shewing a tool or machine in which the
plug projects from the stand and is surrounded by a cylinder formed in two parts
or halves hinged or jointed together. The several figures are drawn full size and
similar letters in all the figures represent similar or corresponding parts.
I will first describe my invention by reference to figures 1, and 2.
a, is the frame or stand and b, the hollow bush fitted into the said stand in any
suitable manner; c, is the plug, similar to the plug of the ordinary shears such
plug being either formed or fitted in the centre of the said bush b, in the stand a.
A bottle having been formed in the mould, which, as hereinbefore mentioned, is
adapted to form the neck of the bottle with the mouth having a ring or groove on
its exterior, the mouth of the bottle is heated and placed in the hollow bush b, and

page_text: over the plug c, in the stand a; the mouth of the bottle is turned on the plug c,
within the bush b, by which operation the interior and exterior of the mouth of
the bottle will be smooth and, the openings thereof will be of unifc.a size and
thickness and without the usual "bite" in the interior.
In figures 3, 4 and 5, the plug c, projects from the stand in the centre of a ring
or cylinder b, b', forming a hollow bush; the ring or cylinder is formed in two
parts or halves, the part b¹, working on the joint d, the said part b¹ being also
jointed at e, to a rod f, which is adapted to be operated by a treadle in such a
manner as to allow when the treadle is depressed of the neck of the bottle being
clasped by the cylinder when the mouth of the bottle is passed over the plug;
the figures of the drawing shew the position of the parts when the cylinder is
closed over the mouth of the bottle. The bottle is then turned on the plug in a
similar manner to that hereinbefore described. Instead of the ring or cylinder
being formed in two parts as herein before described and shewn in the drawing it
may be formed in one piece in which case the treadle and connections would not
be required.
Having thus described my said invention and the manner of performing the
same What I claim is :-
Firstly. The method herein described of forming and finishing the mouths of
glass bottles by moulding the mouth in the bottle mould and then finishing the
interior and exterior thereof while in a heated state by revolving it on a plug or
mandril in a hollow bush or cylinder on a suitable frame or stand as and for the
purposes herein before described.
Secondly. The use for finishing the mouths of glass bottles of an apparatus or
tool consisting of a fixed plug or mandril in the centre of a hollow bush or ring or
cylinder adapted to a suitable stand substantially as hereinbefore described and
represented in the accompanying drawing
In Witness whereof I the said Thomas Pyke have hereto set my hand and
seal this nineteenth day of February in the year of our Lord one thousand
eight hundred and eighty three
