Improvements in Lever Bottle Stoppers.

page_text: Improvements in Lever Bottle Stoppers.
I, SEPTIMUS ALEXANDER PARKES, of Holbrook, Park Road, Surbiton, Surrey,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in lever bottle stoppers and has for its
object mainly to provide an improved means of attaching the hook to the lower disc
shaped portion which is made of non-corrodible material such as glass, porcelain,
vulcanite, or the like.
In carrying out my invention the upper portion or head is provided with a
projecting ring to receive the lower portion of the stopper.
This head is also provided with a strong metal plate upon which the lever bears
and which may be curved to give additional strength to the plate. A flange is
also formed on this upper portion which bears upon the edge of the neck of the
bottle.
The lower portion of the stopper is of disc shape and provided with a second dise
shaped piece of smaller diameter forined on its upper side and the latter fits into the
projecting ring on the head.
This second disc has a portion across the centre removed, leaving segments. The
straight edges of these segments are bevelled or rebated and engage with a piece of
metal or other suitable material provided with similar edges, and is slid into position
from one end.
In the centre of this piece of metal is fixed an extension provided with a hook,
projecting from the plate at right angles. This extension passes through the bearing
and cover plates of the upper portion of the stopper, and an arm or lever is secured
to the hook and on pulling this arm over the lower portion is drawn towards the
upper portion.
Instead of having the metal plate with bevelled or rebated edges it may be of
channelled form with the flanges preferably bent inwards at an angle and corre-
sponding grooves are formed in the lower portion of the stopper. The channelled
piece is provided with the hooked projection at the centre as before described and is
also slid in from one end.
Between the lower disc of the lower portion and the upper portion is placed a
band or ring of rubber or other resilient material, and on operating the arm it is
pressed out and forms the joint between the bottle and the stopper.
Thus there is no metal or other corrosive material in connection with the contents
of the bottle and so it is especially applicable to bottles containing pickles and the
like.

Gentleman, do hereby declare the nature of this invention and in what inanner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
This invention relates to improvements in lever bottle stoppers and has for its
object mainly to provide an improved means of attaching the hook to the lower dise
shaped portion which is made of non-corrodible material such as glass, porcelain,
vulcanite or the like.
In carrying out my invention the upper portion or head is provided with a
projecting ring to receive the lower portion of the stopper.
This head is also provided with a strong metal plate upon which the lever bears
and which may be curved to give additional strength to the plate. A flange is also
formed on this upper portion which bears upon the edge of the neck of the bottle.
The lower portion of the stopper is of disc shape and provided with a second disc
shaped piece of smaller diameter formed on its upper side and the latter fits into the
projecting ring on the head.
This second disc has a portion across the centre removed leaving segments. The
straight edges of these segments are bevelled or rebated and engage with a plate of
metal or other suitable material provided with similar edges which is slidden into
position from one end.
In the centre of this plate is fixed an extension provided with a hook projecting
from the plate at right angles. This extension passes through the bearing and cover
plates of the upper portion of the stopper, and an arm or lever is secured to the hook
and on pulling this arin over the lower portion is drawn towards the upper portion.
Instead of having the metal plate with bevelled or rebated edges it may be of
channelled form with the flanges preferably bent inwards at an angle and corres-
ponding grooves are formed in the lower portion of the stopper. The channelled
piece is provided with the hooked projection at the centre as before described and is
also slidden in from one end.
Between the lower disc of the lower portion and the upper portion is placed a band
or ring of rubber or other resilient material, and on operating the arm it is pressed out
and forms the joint between the bottle and the stopper.
Thus there is no metal or other corrosive material in contact with the contents
of the bottle and so it is especially applicable to bottles containing pickles and
the like.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which Fig. I is an elevation partly in section
of my improved stopper, Fig. 2 is a plan of the same and Fig. 3 is a detail view.
The upper part or head A of the stopper is provided with an internal flange a
forming a step and adapted to receive the upper part of the dise B which may be
formed of porcelain or similar material. The upper part of this disc is raised above
the lower and is of smaller diameter so as to extend within the flange a. It is also
formed with a central groove б the edges of which are bevelled or undercut, the
groove being adapted to receive the bevelled plate C which can be slidden into the
groove from either end. Between the top A of the stopper and the disc B
the rubber ring D is inserted placed round the outside of the flange or lip which
forms a recess to receive it. The complete stopper is fitted within the neck of the
bottle or jar E and the rubber ring D is placed so that when the disc B is compressed

page_text: towards the top, the ring is collapsed and is caused to bulge out against the inside of
the neck forming a tight joint.
To effect this purpose in a simple manner I form the plate C with an extension c
passing through a hole in the cover plate a¹, this plate consisting of a dished or
concave metal dise fitting on top of the flange a. The lever F which is of the usual
kind employed in connection with lever stoppers is fitted to the hook cand operating
through the cam like end so as to press the disc and the top of the stopper
together.
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) In an improved lever stopper, the combination with a cover plate fitted to the
head of the stopper and a flange on the latter, of a disc of porcelain or like material
at the lower side of the stopper, a groove in the said disc, a plate sliding in the said
groove having a hook on its upper side to which the usual lever is attached, and a
rubber ring between the said dise and the top of the stopper, substantially as and
for the purposes.
(2) In an improved lever stopper the combination of a cover plate fitted to the rim
of the stopper, and a flange on the latter, of a dise of porcelain or like material of
stepped form, the upper part passing within the said flange, a groove in the upper
part of this disc, a sliding plate engaging in the said groove having a hook at its
upper side to which the lever is attached, and a rubber ring placed between the disc
and the top of the stopper, substantially as and for the purposes specified.
(3) The improved lever stopper having a grooved porcelain disc, a bevelled plate,
a flange in the said plate, a cover plate, a collapsing rubber ring and means for
operating the said parts substantially as described and shown in the accompanying
drawings and for the purposes specified.
Dated this 1st day of January.
