Improvements in or connected with Bottles and Bottle Stoppers..
We, WILLIAM HENRY WATTS of 54 Marshall Street, Golden Square
Gunmaker, and HORACE EVEREST of 381 Goldhawk Road, Hammersmith,
Clerk, both in the County of Middlesex do hereby declare the nature of this
invention to be as follows :-
The invention relates to that class of bottle stopper which is generally formed
of vulcanite and provided with a screw thread adapted to engage a corresponding
thread formed in the bottle neck and which makes a tight joint with the bottle
neck by the aid of co-acting ring of india-rubber or other material and the
object of the present invention is to substitute for the screw threads a simple
device which will be easier and less expensive to produce and at the same time
equally efficient in use.
In carrying the invention into effect the bottle neck is formed upon the interior
and at diametrically opposite points thereof with a projecting vertical rib, and at
the bottom of this vertical- rib and disposed at right angles thereto is a short
horizontal rib or lug which latter are upon their undersides formed inclined tapered
or wedge shaped.
The stopper which may be formed of any suitable material is upon each side
formed with a vertical groove corresponding with the vertical rib of the bottle, but
the vertical groove of the stopper is formed of such width or the stopper is so cut
away as to enable the same to receive a partial rotation and at the bottom of the
vertical groove and at right-angles therewith the stopper is provided with a groove
or projection adapted upon the rotation of the stopper to engage the wedge or lug
of the bottle.
The vertical rib in the bottle neck in conjunction with the groove in the stopper
acts as a guide to the stopper when the latter is placed in position in the bottle
neck and the wedge shaped lug or projection upon the bottle neck in conjunction
with the projection or groove of the stopper acts to force the same firmly down
upon the rubber, ring or cushion or other packing and thus make a perfectly tight
joint between the parts.
In some cases the arrangement herein before described is reversed that is to say
vertical grooves terminating in approximately horizontal but inclined offset-grooves
are formed upon the interior of the bottle neck upon diametrically opposite sides
thereof, and the stopper is provided with corresponding laterally projecting studs
formed by a metal pin passing transversely through the stopper or otherwise and
adapted to traverse the vertical grooves and upon partial rotation to engage the
inclined offset-grooves or recesses.
By the means hereinbefore described the cost of production of the bottle and the
co-acting stopper is materially reduced as compared with the screw threads
herein before referred to and in use the stopper is more easily inserted and
withdrawn and quicker in its action.

page_text: glass is upon each side provided with a corresponding laterally projecting cylindrical
stud b' formed by a pin of metal fitted into a hole passing transversely through the
body of the stopper 6 so as to project beyond the same, or the studs b¹ might be
otherwise formed as hereinafter described.
The neck a of the bottle at a' is formed with an annular conical seat for a ring
of cork, rubber, or other suitable packing material 62 fitted upon the stopper b
immediately beneath the head thereof, and which is caused to form a tight joint
between the parts in the manner hereinafter described.
b
Upon the insertion of the stopper 6 into the bottle neck the projecting cylindrical
studs b' travel down the vertical groove a', and upon a partial rotation being given
to the stopper 6 engage the inclines a³ of the offset grooves a² in the bottle neck,
and act in conjunction therewith to force the rubber, cork, or other packing ring
or cushion 6 firmly down into the conical or inclined seat in the bottle neck, and
thus make a perfectly tight joint between the parts.
If necessary, the transverse pin forming the studs b¹ may be fastened in position
by any suitable means such as a cement which will not be injuriously affected by
the contents of the bottle.
Although the projecting cylindrical studs b₁ are herein before described as formed
of a metal pin passing transversely through the stopper it will be evident that such
pin might if desired be formed of other suitable material.
If desired, instead of forming a hole completely through the stopper to receive
the pin as herein before described indentations or recesses may be substituted
therefor, and the studs 61 may be formed of separate short lengths or pins inserted
therein.
By the means hereiubefore described the cost of production of the bottle and
the co-acting stopper is materially reduced as compared with the screw arrange-
ment hereinbefore referred to, and in use the stopper is more easily inserted and
withdrawn, and quicker in its action, thus materially facilitating the bottling
operation.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
-
The combination of a bottle formed with two vertical grooves in the neck
terminating in offset grooves, the upper sides of which are shaped as inclines or
wedges, and a stopper furnished with a ring of cork or other packing at its upper
end, and at its lower end transversely perforated or recessed, and fitted with a pin
or pins of metal or other suitable material projecting in the form of studs adapted
to co-act with the said inclines of the bottle substantially as herein shown aud
described.
