PROVISIONAL SPECIFICATION.
Improvements in Stoppers for Bottles, Jars, and the like.
I, JOHN JAMES VARLEY, of No. 268, South Lambeth Road, in the County of
Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to screw stoppers for bottles, jars and the like.
Such stoppers are usually provided with an india rubber or other ring or seating
placed upon the neck or stem of the stopper, which it has been before proposed to
form with a single groove forming a ridge over which the ring was stretched the
upper edge of the ring entering the groove and the lower edge embracing part of
the stem; the middle of the ring or seating resting upon the ridge was therefore
caused to project beyond the edges or was of larger diameter than the edges with
the result that only about 3rd of the ring acted as a seating and was by this fact
soon compressed at that part and rendered unsuitable for the object for which it
was intended.
My invention has for object to render the entire surface of the ring available for
making the joint in the bottle neck and for this purpose in place of a single groove
or ridge I make a number, (preferably 4 or 5) of grooves upon that part of the
stem on which the seating is placed so that when an india rubber ring is stretched
upon the ridges between the grooves the inner part of the ring will partly enter
the grooves and the outer surface of the ring will be therefore slightly depressed
between the ridges upon which the ring rests. That part of the ring will thereby
be caused to retain its elasticity and at the same time be sufficiently rigid to make
a perfect joint that is to say the whole surface of the ring will not be equally
compressed but the part of the ring between the grooves will be protected by the
part which rests upon the ridges and will be maintained in an uncompressed
state.
A screw stopper made according to my invention and fitted with an india rubber
ring will not require to be screwed into the bottle with such force as is now
necessary and can be much more easily removed.

COMPLETE SPECIFICATION.
Improvements in Stoppers for Bottles, Jars, and the like.
I, JOHN JAMES VARLEY, of No. 268, South Lambeth Road, in the County of
Surrey, Engineer, 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 invention relates to screw-stoppers for bottles, jars and the like.
Such stoppers are usually provided with an india-rubber or other ring or seating
placed upon the neck or stem of the stopper, which it has been before proposed to
form with a single groove forming a ridge over which the ring was stretched, the
upper edge of the ring entering the groove and the lower edge embracing part of
the stem; the middle of the ring or seating resting upon the ridge was therefore

the result that only about rd of the ring acted as a seating and was by this fact
soon compressed at that part and rendered unsuitable for the object for which it was
intended.
My invention has for object to render the entire surface of the ring available
for making the joint in the bottle neck and for this purpose in place of a single
groove or ridge I make a number, (preferably 4 or 5) of grooves upon that part of
the stem on which the seating is placed for the purpose hereinafter described.
In order to enable my invention to be fully understood 1 will describe the same
by reference to the accompanying drawing, in which :—
Figure 1 is an elevation of a screw-stopper made according to my invention:
Figure 2 is a similar view shewing the india-rubber ring or washer in section :
Figure 3 is an elevation of the stopper without the ring; and,
Figure 4 is a view similar to Figure 2 shewing a slight modification of the
stopper.
Similar letters of reference indicate similar or corresponding parts in the
several figures.
a represents a stopper made of any suitable material such as wood, composition
or vulcanite as usual, and 6 is the screw-thread formed thereon adapted to screw
into a corresponding screw-thread in the neck of the bottle to be closed.
c, c represent the grooves which I form upon that part of the stem of the stopper
on which the seating is placed, and d represents the usual india-rubber ring forming
the seating. In the drawing only three grooves c are shewn for the sake of
clearness but in practice I use four or five grooves.
When this ring is placed upon a stopper provided with grooves as described the
inner part of the ring will partly enter the grooves c, c and the outer surface of the
ring will therefore be slightly depressed between the ridges upon which the ring
rests, as clearly shewn in Figures 1, 2 and 4. This part of the ring will thereby
be caused to retain its elasticity and at the same time be sufficiently rigid to make
a perfect joint, that is to say, the whole surface of the ring will not be equally
compressed but the part of the ring in the grooves c, c will be protected by
the part which rests upon the ridges and will be maintained in an uncompressed
state.
The stopper shewn in Figure 4 is substantially the same as that represented in
Figures 1, and 3, except that I only shew one groove which is made around a
bead on the stopper just below the under side of the head.
e represents a slot which is sometimes formed in screw-stoppers when made of
wood for the purpose of allowing for the contraction and expansion of the
material.
A screw-stopper made according to my invention and fitted with an india-rubber
ring as described will not require to be screwed into the bottle with such force as
is now necessary and can be more easily removed from a bottle.
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. A screw-stopper for bottles, jars and the like having a number of grooves
upon that part of the stem in which the seating is placed as, and for the purpose,
hereinbefore described.
2. A screw-stopper having grooves c, c on the stem thereon adapted to receive
an elastic seating such as d substantially as, and for the purpose, hereinbefore
described and illustrated in the several figures of the accompanying drawing.
