This Invention relates to an improved Bottle stopper which is applicable to
Bottles of every variety and which need not be specially made for it.
There are several varieties of Bottle stoppers patented and made all of which
have some advantages and some disadvantages.
In the best of these the Bottles have to be made specially for the purpose with
necks screwed either inside or outside or with other special provision for the stopper,
and in making them there is considerable loss & expense because any variation or
imperfection in the screwed part makes the Bottle useless.
In others the Bottle may be of the ordinary type but the stopper or its fittings
must be specially adapted to each Bottle for the reason that as Bottles are ordinarily
made there is great variety in the diameter of the neck, and in the length of the
same from the top to below the band.
My Invention claims and is intended to avoid both these difficulties & I effect this
in the following manner.
I first take a strap which is fastened round the Bottle below the band either by
being wired at the ends or in any convenient way. On each side are holes in which
the bands coming down from the Boss are so fixed that they can swing. The
Boss is a centre piece screwed internally to receive the stopper and having arms
or bands running down on each side of the neck of the Bottle to the strap on which
they can swing. The Boss is raised by these Bands so high above the Bottle that when
the stopper is unscrewed it with the nipple can swing off and leave the top of the
Bottle clear.
The stopper is formed in two Pieces first the stopper which is a circular piece
screwed outside to fit into the Boss.
Secondly the nipple which is attached to the stopper by rivetting but so that in
screwing in the stopper the nipple does not revolve with the stopper.

page_text: This nipple is formed conical with a flange at top and bottom. The flange at top
is larger than the diameter of the Bottle, and the lower flange goes into the Bottle.
On the conical part of the nipple.is_placed a ring of India Rubber which is held in
its place by the said two flanges.
In attaching the stopper to the Bottle, the strap with the arms in their place is
fixed round the Bottle. The Bottle is then made tight by simply screwing down the
stopper.

I, THOMAS RAWSON of 6 Wimborne Street Hoxton in the County of Middlesex,
Engineer and Tool Maker, do hereby declare the nature of this invention and in
what manner the same is to be perforined, to be particularly described and ascertained
in and by the following statement :-
There are several varieties of Bottle stoppers made all of which have some advantages
& some disadvantages.
In the best of these the Bottles have to be made specially with the provision of a
neck screwed inside or outside or with some arrangement for attaching the stopper
& in making them there is a considerable loss & expense because the least difference
or imperfection in the screwed part or the neck of the Bottle makes the Bottle
useless.
In others the Bottle may be of the ordinary description but the stopper or its
fittings have to be made specially adapted to each Bottle for the reason that as Bottles
are ordinarily turned out there is great variety in the diameter of neck and in the
length of the same to below the band.
This invention claims to avoid both these difficulties and it is carried out as
follows
I first take a strap f. (see drawing which is fastened round the bottle below
the band either by being wired together at the two ends or in any convenient way.
It has holes one on each side of the bottle in which the arms C. (see drawing)
coming down from the Boss B. are so fixed that they can swing. The Boss B. is
formed of a center piece screwed internally to receive the stopper and is raised above
the top of the Bottle so far as to allow it with the stopper & nipple to swing off the
Bottle when screwed back but having still hold of the Boss.It has two arms C.
running down one on each side to the strap, in which they swing.

page_text: The stopper is formed in two parts, first the stopper A. which is screwed externally
to fit the Boss. Secondly the nipple D which is attached to the stopper by rivetting
but so that in screwing down the stopper the nipple does not revolve with the stopper.
This nipple is formed by preference conical with a flange at top & bottom.
The flange at top is larger than the diameter of the mouth of the bottle but smaller
than the internal diameter of the Boss so that the stopper & nipple can be with-
drawn into the Boss. The lower flange goes into the neck of the Bottle-The upper
flange is cast with the nipple. The lower flange may be cast solid with the nipple or
screwed or rivetted on. On the conical part of the nipple is placed a ring of India
Rubber or other elastic substance E which is held in place by the said two flanges.
The Drawing shows, fig. 1. the stopper & Bottle in section, fig. 2. elevation of
Bottle with stopper screwed down in place. Fig. 3 Bottle with the stopper screwed
back & being swung off the Bottle.
In attaching the stopper to the Bottle the strap is fixed round the Bottle, the bent
ends of the arms are slipped into the holes in the band. The Bottle is then made tight
by simply screwing down the stopper.
I am aware that stoppers have been made with many of these parts, or parts similar
in form more or less combined but none have been successful for want of what I claim
as the essential part of my invention, The nipple made as herein described separate
from and attached as described to the stopper so that it can swivel and not revolve
with the stopper.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is
First. The stopper constructed substantially as herein before described and to be
made, including the combination of the Boss & arms swinging on the strap and the
stopper composed of the two parts herein described so attached that they do not
revolve together but the nipple swivels on the stopper the nipple formed of a center
piece and flanges substantially as described.
Secondly. The stopper made as above described so that it can be withdrawn
entirely through the Boss.
