I WILLIAM CAMPBELL WOOD, 55 Kirkwood Road, Nunhead, Surrey, Clerk, do
hereby declare the nature of this Invention to be as follows:-
The Improvement consists in making the inside of the neck of bottles & other
vessels slope downwards for a certain distance where 1 there form a sloping or inclined
ring or ledge (from this point the remainder of the neck is continued in a straight
line). This inclined ring or ledge may be formed at any distance from the mouth
within the neck of the vessel. It slopes upwards from the inside of the neck towards
the centre at a very acute angle. Upon this inclined ring or ledge rests the bottom
of the stopper which lower part being made of cork or any other elastic material is
by pressure from the top tightly pushed against the inclined ledge & thus allows the
elasticity of the cork to form a perfectly air & water tight joint.
At the mouth of the neck are 2 wide slots to allow the passage of the lugs
formed on the upper part of the stopper. On the right hand side only of each slot
is a groove made in the rim to allow the entrance of the lugs. The entrance is the
deepest part of the groove, the groove becoming gradually less deep until it is at
length flush with the inside of the neck. This lessening of the depth of the groove
when the stopper is in position prevents the lugs making a complete revolution,
allowing them only to make a quarter revolution & yet firmly hold when pressed
within the grooves.
The upper part of the stopper I inake of glass, wood, metal, porcelain, or any com-
position. On the sides are 2 lugs to fit the slots in the mouth of the vessel. Through
this upper part passes a spindle on which it revolves. Beneath the 2 lugs is a plate

page_text: cast or fastened to the spindle. Beneath this plate is a screw or thread on which the
cork is screwed, thus rendering it easy to be replaced at any time. This lower part
whether of cork or any other material is made sloping to fit the corresponding part
of the neck of the vessel.
On putting the stopper in the neck a slight pressure forces the cork on to the inclined
ring or ledge. At the same time the lugs enter the slots in the mouth & by a slight
turn enter the grooves & become firmly held. The same slight turn the reverse way
completely unlocks the stopper.
The advantages I claim for this Invention are; that the pressure from the top
passing in a downward direction causes a perfectly air & water tight joint, together
with simplicity of parts and easy manipulation.

An Improvement in Stoppering Bottles, Jars, and other Vessels
Used for Ale, Stout, Aerated and Mineral Waters, Wines, and the
like.
WILLIAM CAMPBELL WOOD 55 Kirkwood Road, Nunhead Surrey Clerk 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:
My improvement consists in making the inside of the neck of bottles and other
vessels slope downwards towards the centre, where I there form a sloping or inclined
ring or ledge (from this point the remainder of the neck may be continued in a straight
or curved line.) This inclined ring or ledge may be formed at any distance from the
mouth, within the neck of the vessel. It slopes upwards from the inside of the neck
towards the centre at a very acute angle. Upon this inclined ring or ledge rests the
bottom of the stopper, which lower part being made of cork or any other elastic
material, is by pressure from the top pushed against the inclined ring or ledge and
thus allows the elasticity of the cork or other material to form a perfectly air and
water tight joint.
At the mouth of the neck are two wide slots to allow the passage of the two lugs
formed on the upper part of the stopper. On the right hand side only of each slot
is a groove made in the rim or neck to allow the entrance of the lugs. The entrance
is the deepest part of the groove, the groove becoming gradually less deep until it is
at length flush with the inside of the neck. This lessening of the depth of the groove,
(when the stopper is in position) prevents the lugs making a complete revolution,
allowing them to make only a quarter revolution and yet hold firmly when turned
into the grooves.
The upper part of the stopper, I make of glass, wood, metal, porcelain, or any
composition. On the sides are the two lugs before mentioned to fit the grooves in
the mouth of the vessel. Through the upper part of the stopper passes a spindle on
which it revolves. Beneath the two lugs is a plate cast or fastened to the spindle.
Beneath this plate is a screw or thread on which the cork or other material is screwed,
thus rendering it easy to be replaced at any time. This lower part whether of cork
or other material is inade sloping to fit the corresponding part of the neck of the
vessel.
On putting the stopper in the neck, a slight pressure forces the cork or other material
on to the inclined ring or ledge. At the same time the lugs enter the slots in the
mouth and by a slight turn enter the grooves and become firmly held. The same
slight turn the reverse way then completely unlocks the stopper.
The advantages I claim for this Invention are, that the pressure from the top
passing in a downward direction causes a perfectly air and water tight joint, simplicity
of parts and easily manipulation.

at the entrance V, and gradually lessening until it is flush with the inside of the neck
at X, D continuation of neck.
Fig. 2 is a plan of the top of the neck, E, E being the slots, where the lugs H, H
or figure 3, & L L on figure 4 enter; the dotted lines F, F show how the grooves in
the neck gradually decrease.
Fig. 3 shows the stopper in elevation, G being the upper part, H, H the two lugs,
I the plate & K, K the spindle and screw, and J the cork or other elastic material.
Fig. 4 is a bottom view of stopper, L L being the two lugs corresponding with the
letters H H on Fig. 3.
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 :
First The formation on the interior of the mouths of vessels, of an inclined ring
or ledge, and two graduated grooves at the mouth with a slot or aperture forming
entrance to each groove as described.
:
an
Secondly The use in combination with such inclined ring or ledge, of a stopper
with corresponding projections as described, and with the upper part of the stopper
movable, and the lower part capable of being unscrewed and renewed the
stopper being capable of being brought by a part of a rotation into airtight contact
with the inclined ring or ledge in the neck of the bottle or vessel.
Dated this 28th day of December 1887.
