Improvements in the Manufacture of Bottles.
I, STEPHEN THISTLETHWAITE, of 35, Market Street, Manchester, in the County
of Lancaster, Surgical Instrument Maker, do hereby declare the nature of this
invention to be as follows;-
This invention relates to the manufacture of bottles of various forms such as
are ordinarily used by chemists and medical men and are closed by means of
ordinary corks, the object being to reduce the stock of corks necessary for a
number of bottles of various sizes, and to use one standard size of cork for various
sizes of bottle, and so to effect a great saving of time in selecting a suitable size
of cork for each bottle.
For this purpose instead of changing the plug upon which the bottle neck
is formed by the dies of the usual tongs for making these bottles, whenever a
different size of bottle neck is to be made, I now make use of one plug only, and
this plug is considerably tapered from the root to the point.
When forming a bottle neck I take care that the dies are held firmly to retain
the metal" or glass close against the plug, and thus when the neck is com-
pleted the inside of the bottle neck is conical and decreases in diameter from
the mouth to a point about ", or half an inch down the neck or for a distance
sufficient to form a perfectly water-tight and air-tight joint with the cork which is
also slightly tapered.
When forming the necks of the larger sizes of bottle more "metal" or glass
than usual is used in order to keep the appearance of the bottle symmetrical.
Such additional "metal" will also strengthen the bottle at the neck where it is
usually weakest.
It will be evident that by making the bottle neck in this manner one size
of cork will fit the necks of many sizes of bottles.

by means of corks.
The object of my invention is to enable one standard size of cork to be em-
ployed for bottles of various sizes, in order to effect a reduction in the number
of corks that under ordinary circumstances it is necessary to keep in stock, and in
the time occupied when a suitable size of cork has to be selected for each bottle.
In the accompanying drawing various sections of the necks of bottles are shown
to which I hereinafter refer and describe similar letters indicating similar parts.
By the ordinary means adopted for making bottle necks after being blown in
the mould and the moulded bottle coming out similar to the form shown in
Fig. 1, the neck a having been broken off the blowers tube, the neck is then
reheated and the bottle clamped at the end of a rod, by which it is rolled on a
table while the tool (Fig. 2) is grasped in the hand by the attendant, the neck
rotating between the profiles and is thus formed. The plug of the tool
(Fig. 2) merely forms a point around which the bottle neck can rotate, and as
long as the outside of the neck is a good shape, the inside may be quite a loose
fit in the plug: Usually the neck of each size of bottle is made on its own tool
with a smaller or a larger plug, thus the workshop is provided with 20 oz. 10 oz.
8 oz. 6 oz. and other sizes of tools or tongs.
"
For the purpose of this invention, instead of changing the plug upon which
the bottle neck is formed by the dies of the ordinary tongs for making bottles
whenever a different size of bottle neck is to be made, I now make use of one
plug only, and this plug is considerably tapered from the root to the point.
When forming a bottle neck I take care that the dies are held firmly so as to
retain the metal or glass close against the plug, and thus when the neck is
completed the inside of the bottle neck is conical and decreases in diameter from
the mouth to a point, at a distance sufficient to form a perfectly water-tight and
air-tight joint with the cork which is also slightly tapered.
When forming the necks of the larger sizes of bottles more
than usual is employed in order to keep the appearance of the bottle symmetrical;
Such additional metal will also strengthen the bottle at the neck where it
is usually weakest.

Fig. 3 shows a bottle neck made according to this invention. Figs. 4 and 4*
show parts of two ordinary bottles, say 10 oz. and 1 oz. having different sized
necks, and Figs. 5 and 5 show parts of two of the improved construction of
bottles say 10 oz. and 1 oz. having the same internal sizes of neck.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is;-
The improved manufacture of medicine or other bottles by which all bottles
of a set are or may be provided with a neck of a uniform internal diameter, and
of a conical or tapered form at the upper end of the said neck, whereby one
standard size of corks may be used for various sizes of bottles, substantially as
and for the purpose hereinbefore described.
