IMPROVEMENTS IN FORMING THE NECKS OF BOTTLES AND OTHER HOLLOW VESSELS TO BE USED WITH CERTAIN KINDS OF STOPPERS
Year: 1885

page_text: I JOHN BLOCKSIDGE of Great Hampton Street, Birmingham, in the County of
Warwick, Manufacturing Jeweller and Silversmith do hereby declare the nature of
said invention for "IMPROVEMENTS IN FORMING THE NECKS OF BOTTLES AND
OTHER HOLLOW VESSELS TO BE USED WITH CERTAIN KINDS OF STOPPERS "
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
and
My invention has for its object the production or formation of the necks of bottles,
jars and other hollow vessels to be used in connection with certain kinds of
stoppers, as I will hereinafter particularly describe-The production or manufacture
of the necks of the said bottles or other hollow vessels is much simplified and
economised; and my said invention consists in forming or producing within the
inside of the neck of the bottle, stopper holding shoulders or projections which
close and fix the stopper when the said stopper is slightly turned and rotated; and
my invention has especial reference to the formation or production of these over-
hanging lugs or shoulders by bulging or gathering inwards the material of the neck
of the bottle as hereinafter particularly described.
Figure 1 represents in side elevation, figure 2 in front elevation and figure 3 in
transverse vertical section the neck of a bottle constructed according to my inven-
tion. Figure 4 is also a transverse vertical section taken at right angles to figure 3.
Figure 5 is a plan of the neck of the bottle showing the internal projections or
shoulders upon opposite sides of the inside of the said neck. Figure 6 is a trans-
verse vertical section on the dotted lines A B figure 1. Figure 7 is the kind of
stopper to be used in connection with the specially formed neck constituting my
invention. Figure 8 is the neck of the bottle figure 3, and the stopper figure 7
upon a larger scale. The said stopper is shown in use, closing the mouth of the
bottle, and held in position by the cross end acting upon the undersides of the
inclines of the projections or overhanging shoulders as represented. Figure 9 is a
cross section of the neck of the bottle showing the position of the end of the stopper
when the said end is introduced into the neck, and figure 10 represents the position
of the cross end when the stopper is fixed and the bottle closed. Figure 11 represents
a modification of the neck formation, the planes or undersides of the projections being
disposed at a slight angle, to give a greater drawing to or binding power. Figure 12

page_text: is also a modification in which the top part of the neck is made slightly elliptical
and the metal of the bottle bulged outwards on the shorter axis instead of inwards,
as in the former case.
The same letters of reference indicate corresponding parts in the several figures
of the Drawing, and for convenience of description, I will describe my invention as
applied to a bottle, although the improvements are equally applicable to jars and
vessels for various purposes.
a is a bottle and 6 is the neck thereof, and c c are stopper holding shoulders or
contractions of the said neck formed at a short distance from the mouth of the
bottle. This contracted or bulged in part is best seen in the plan figure 6 taken
upon the dotted lines A B figure 1. The shoulders or overhanging lug projections
situated on opposite sides of the inside of the neck of the bottle are formed prefer-
ably at the time when the bottle is made; that is to say, the mould within which
the bottle is fashioned or blown, has upon opposite sides of the neck of the mould,
rises or projections corresponding to the shape or throttling inwards that is required
to be given to the inside of the neck to form the necessary opposite protuberances
-c c, under which the stopper end engages.
The pinching or gathering inwards of the metal of the bottle, makes the sides
even and uniform in thickness.
In figure 12 d d are bulgings from the inside of the neck of the bottle, so as to
form recesses or shoulders on opposite sides, and into these opposite recesses, the
T or cross end of the stopper takes for closing and fixing the stopper within the
bottle.
In order to apply my invention to existing bottles, it is only necessary to take
an ordinary bottle with a uniform neck, and heat or soften the glass or material of
which the bottle is composed, and by impressing tools pinch or gather inwards the
neck and so form the necessary shoulders or lug projections as described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
:
Forming the necks of bottles to be used with T or like cross ended stoppers, by
bulging or gathering inwards the sides or the material of the neck of the bottle so
as to contract or shorten the orifice of the said neck in one direction, and so
thereby form shoulders or standing out lugs or sides, and under the overhanging
edges of which, the end of the stopper takes and locks. The production or forma-
tion of the shoulder parts being conducted and carried out in the manner and for
the purpose as described and illustrated in figures 1, 2, 3, 4, 5, 6, 8, 9, 10 and 11
of the accompanying Drawing; also the modifications described and represented in
figure 12, in which the sides of the neck of the bottle are bulged outward instead
of inward for the end or side of the stopper to engage in for the purpose as
described and set forth.
