Improvements in Stoppering Bottles for Aerated and other
Liquids.
I THOMAS TERRELL of No. 1 New Court Temple in the City of London, Barrister
at Law do hereby declare the nature of this Invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to improvements in stoppering bottles for containing aerated
and other liquids and relates to improvements upon my invention described in the
Specification of Letters Patent now being applied for by me and dated 3rd
December 1886, No. 15,826 in which the stopper when removed to discharge the
contents is retained by a loop which connects it to the neck of the bottle ready for
use again and in the application of a lever arm or catch for drawing down the
stopper tightly upon the neck or valve seating of the bottle and the inlet valve when
the bottles are filled with liquids under pressure.
My present improvements consist in the form and arrangement of the parts which
connect the stopper to the bottle a plate being connected to the collar mounted on the
neck of the bottle, its other end being hinged or connected to a collar mounted in a
suitable groove formed around the upper part of the stopper and so hinging or
connecting the latter permanently to the bottle.
On the opposite side of this collar on the stopper a similar plate is mounted
which has a suitable slot or opening through which a lever arm or catch (threaded
or mounted on the collar around the bottle neck as heretofore) is passed and then
pulled over to close the stopper down tightly on to its seating and so make a tight
joint to close the bottle.
By this improved arrangement I find that the pull on the stopper is more direct
and even and consequently makes a better stoppering.
The connecting plates, lever arm and collars may advantageously be made of mild
steel or other suitable metal.
And in order that my invention may be clearly understood and readily carried
into practice I will proceed to describe the same with reference to the accompanying
drawings.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an exterior view of the neck of an aerated water bottle having my
improved stopper applied thereto closed down.
Figure 2 is a similar view with the stopper raised in the process of opening and
Figures 3 show front and back views of the stopper and its connecting parts the
stopper a in this arrangement being made of porcelain, glass or other hard material,
vertical and horizontal sections of which are shown by Figures 4.
The stopper a is connected to the neck of the bottle by plates of metal (advan-
tageously made of mild steel) the back plate or hinge piece c¹ being mounted at
one end on the collar d around the neck of the bottle and at its other end on the
collar a arranged in a groove formed around the upper part of the stopper a which
is thus permanently connected to the bottle. b and may be formed either with or
without an inlet valve (as previously described) according to the purpose for which it
is required.
The plate e¹ is mounted on the collar a¹ on the opposite side of the stopper to that
on which the hinge piece c¹ is mounted (as shown by Figures 3) the plate el having
a hole or slot 2 formed therein and through this slot the lever arm is threaded
which is then pulled over and draws down and retains the stopper tightly on to its
seating.
Figures are detail views showing the construction of the stopper a and the
groove or channel formed therein for the collar a¹; care being had to mount the
metal plates c¹ and e¹ in such a manner that when the stopper is closed down, they
lay close up against it as shown in Figure 1.
Figures 5, 6, 7 and 8 show a modified arrangement of the parts of my improved
stopper and consists in constructing the stopper in two parts, the top part or cap a
being formed advantageously of tin-plate having a block of cork a pressed into and
retained by the turned in edges of the part a.
The cork a² is advantageously formed conical and the inner surface of the mouth
of the bottle being formed conical to correspond as shown in dotted lines in
Figure 8 so that the cork has a large area on its seating.
The lever arm is mounted as before described and the hinge pieces or plates c¹ and e¹
are mounted as shown in Figures 5 and 6 on lugs or ears a³ and a respectively
on the cap or part a the hinge piece e¹ being mounted at its other end on the collar d
as before thus permanently securing the stopper to the bottle neck.
The lever arm acts as before to draw down and retain the stopper tightly on the
mouth of the bottle.
This arrangement is more particularly applicable for bottling beer and wines.
The lever arm is set off from the projecting collar g on the neck of the bottle
part of which had heretofore to be chipped or ground off to admit of the lever arm f
being mounted upon the collar d.
Lugs or projections d' d' are fixed upon the collar d on each side of the plate e¹
thus causing that part of the collar d to project sufficiently to avoid the cutting away
of the collar or bead g on the bottle . I also find it advantageous to place the
twisted ends of the wire collar d in a slot c cut in the back strap or hinge piece c¹
by which means the relative positions of the combined parts are maintained."
In every case the lever arm should be so mounted that when it is pulled over
and the stopper a closed down the pull or pressure of the slotted plate e¹ will be
inside of the bearing of the lever arm f so that the lever arm will be held down by
the pull or pressure and not have any tendency to open.
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 :-
1. The application of the lugs or projections d¹ d¹ on the collar d substantially as
described for the purpose of keeping the lever faway from and thus avoiding the
cutting away of part of the neck of the bottle as heretofore.

page_text: 2. The fastening of the ends of the wire collar din a slot c³ cut in the hinge piece c¹
substantially as shown and described thus preventing the relative parts of the
combination from becoming displaced and requiring adjustment.
3. The improved combination of the bottle b with wire collar d lugs d² d¹ lever f
straps or plates el cap or plate a and cork or other elastic stopper a³ substantially
as shown and described.
4. The combination last described substituting for the cap or plate a and cork a²
the earthenware glass or other hard stopper a (shown in Figures 1 to 4) fitted with
wire collars a¹ and d and cork rubber or elastic flange a substantially as shown and
described.
