Improvements in Stoppers for Jars and other like Receptacles.
We, HARRY ALBERT GRIFFITHS, of 37 Powell Street in the City of
Birmingham, Engineer, and RICHARD HANSON GRIFFITHS, of Hazeldeane,
Pershore Road, Selly Park, in the County of Worcester, Clerk, d hereby declare
the nature of this invention to be as follows:-
This invention consists of improvements in lever or similar stoppers for jars and
like receptacles, our object being to provide some efficient and durable means
whereby the stopper is secured within the mouth of the jar or other receptacle than
exists with the stoppers at present in use.
In the application of our invention in one convenient manner to the construction
of a lever type metallic stopper for a jar or bottle containing pickles, preserves or
the like, we form the head or upper par with a projecting ring or body serving as
a socket for the reception of the base or lower part of the stopper. Within the
interior space between the head and the base of the stopper we insert a pressure
plate, preferably of steel, having its central portion dished or recessed to form a
seating for the closing lever hereinafter described and having projections, preferably
four in number, from its under side seating upon an internal flange or shoulder of
the stopper head.
The stopper base is formed to a cup or other suitable shape, and has a pair of lugs
or ears projecting within the space between the head and base of the stopper,
through which we pierce slots or apertures to admit the head or cross piece of the
closing lever or its equivalent.
The ends of the cross piece are recessed to fit within the slotted projecting
lugs or ears, and thus a hinge or pivot connection is formed between the lever and the
base of the stopper.
When the stopper is opened, or before its insertion within the month of the jar or
bottle, the flat part of the lever cross piece rests upon the dished surface of the
pressure plate hereinbefore described, and its stem or long arm projects vertically
through a slot or aperture in the head of the stopper. An external flange or
shoulder is provided upon the stopper head, which on insertion of the stopper
within the jar or bottle, rests upon the upper extremity of the neck. When thus
inserted within the jar, the stopper is secured, and an air tight joint is formed by
depressing the projecting stem of the lever to its horizontal position, and thus
causing the short end or cross piece of the lever to raise the base whilst firmly
pressing the head upon the neck end. In this manner the ring of india rubber or

page_text: other suitable material placed between the head and base of the stopper is expanded
tightly against the interior surface of the jar mouth, thus forming an air tight
joint.
A depression or seating is provided on the outer surface of the head to receive
the lever stem when in its horizontal or closed position, and thus to bring it flush
or level with the top of the head. The outer end of the stem is formed suitably
for convenient manipulation by the fingers.
The head or upper part of the stopper is preferably formed from a flanged ring
or body having a top plate or cap secured to the same in any ordinary manner. To
prevent independent movement or rotation of the base and the pressure plate and
lever relatively to the head, we form indents or projections from the inner surface
of the flanged ring, engaging with, or acting as stops against the pressure plate.
We do not limit the application of our invention to any particular form or
pattern of stopper, but adapt the same with such modifications as may be necessary
to the construction of stoppers of varying designs to suit the particular receptacles
for which they are required.

We, HARRY ALBERT GRIFFITHS, of 37, Powell Street, in the City of
Birmingham, Engineer, and RICHARD HANSON GRIFFITHS, of Hazeldeane,
Pershore Road Selly Park, in the County of Worcester, 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:-
This invention consists of improvements in lever or similar stoppers for jars and
like receptacles, our object being to provide more efficient and durable means
whereby the stopper is secured within the mouth of the jar or other receptacle than
exists with the stoppers at present in use.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to
Figure 1 is a front elevation of our stopper when open and Figure 2 a similar
view when closed.
Figure 3 is a plan of the complete stopper, and Figure 4 a plan with the top
plate or cap removed.
Figure 5 is a sectional elevation of the complete stopper when open, and Figure 6
a similar view when closed.
Figure 7 is a sectional elevation of the base or lower part of the stopper, and
Figure 8 a front elevation of the same.
Figure 9 is a plan, and Figure 10 a sectional elevation of the pressure plate.
Figure 11 is a plan, and Figure 12 a sectional elevation of the body of the
stopper.
The same reference letters in the different views indicate the same parts.
In the application of our invention to the construction of a lever type metallic
stopper for a jar or bottle containing pickles, preserves, or the like, we form the
head or upper part with a projecting ring or body such as A serving as a socket

page_text: for the reception of the base or lower part B of the stopper. Within the interior
space between the head and the base of the stopper we insert a pressure plate C
preferably of steel, having its central portion dished or recessed to form a seating
for the closing lever D hereinafter described, and having projections preferably
of four in number from its under side for seating upon the internal flange or shoulder
of the stopper head.
The stopper base B is formed to a cup or other suitable shape, and has a pair of
lugs.or ears B' projecting within the space between the head and the base of the
stopper, through which we pierce slots or aperture; B² to admit the head or cross
piece of the closing lever D or its equivalent.
The ends of the cross piece of the lever are recessed to fit within the slotted'
projecting lngs or ears B' and thus a hinge or pivot connection is formel between
the lever and the base of the stopper.
When the stopper is opened, or before its insertion within the mouth of the jar
or bottle, the flat part of the lever cross piece rests upon the dished surface of the
pressure plate hereinbefore described, and its stem or long arm projects vertically
through a slot or aperture in the head of the stopper, as illustrated at Figures 1
and 5. An external flange or shoulder A¹ is provided upon the stopper head,
which, on insertion of the stopper within the jar or bottle, rests upon the upper
extremity of the neck. When thus inserted within the jar the stopper is secured,.
and an air tight joint is formed by depressing the projecting stem of the lever to its
horizontal position, as at Figures 2 and 6, and so causing the short end or cross
piece of the lever D to raise the base whilst firmly pressing the head upon the neck
end. In this manner the ring of india-rubber E or other suitable material placed
between the head and base of the stopper is expanded tightly against the interior
surface of the jar mouth thus forming an air tight joint in the ordinary manner.
A depression or seating is provided on the outer surface of the head to receive
the lever stem when in its horizontal or closed position, and thus to bring
flush or
level with the top of the head. The outer end of the stem is formed suitably for
convenient manipulation by the fingers.
The complete head or upper part of the stopper is preferably formed from a
flanged ring or body A as hereinbefore described with a top plate or cap A² secured
to the same in any ordinary manner. To prevent independent movement or
rotation of the base and the pressure plate and lever relatively to the head, we form
indents or projections such as A³ from the inner surface of the flanged ring or
body A engaging with, or acting as stops against the pressure plate.
We do not limit the application of our invention to any particular form or pattern
of stopper, but adapt the same with such modifications as may be necessary to the
construction of stoppers of varying designs to suit the particular receptacles for
which they are required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we are aware that
lever stoppers have been constructed in two telescoping parts which are drawn
together by a pivoted lever and in which the joint is made by a washer bulged out
when the telescopic parts are drawn together, and we do not claim such construction
generally, but we declare that what we claim is :-
1. An improved stopper for jars and like receptacles consisting of an upper part.
having a body such as A with a pressure plate C fitted thereto, and a lowe: part
such as B having lugs or ears B' slotted for the reception of the lever D,
substantially as and for the purposes hereinbefore described and as illustrated in
the accompanying drawings.
2. In stoppers for jars and like receptacles, the combination of an upper part
consisting of a flanged ring or body such as A having a top plate or cap
A²; with a
pressure late such as C, the hedy A having indents or projections as A³,
substantially as and for the purposes herein before described and as illustrated in the
accompanying drawings.

page_text: 3. In stoppers for jars and like receptacles, the combination of a base or lower
part such as B having ears or lugs as B', with a lever such as D, the ears or lugs
having slots or apertures to admit the head or cross piece of the lever, substantially
as and for the purposes herein before described and as illustrated in the accompanying
drawings.
