Improvements in or relating to the Construction of Screw Stoppers
for Bottles, Jars, or other Vessels.
I, HERBERT MONTGOMERY EDWARDS, of 37, Queen's Road, Brownswood Park, London,
Warehouseman, do hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements in or relating to the construction of
screw stoppers for bottles jars or other vessels and is as follows:-
According to the present invention the screw thread or male screw part of an
internal or male stopper is of a skeleton form advantageously made of a piece of
spirally twisted rod or wire the shape in cross section or size or gauge of said rod or
wire being such as to correspond or fit more or less accurately the spiral groove or
channel forming the female screw thread adapted to receive said male screw.
Or said skeleton male screw may be formed double or from a doubled wire or from
two or more wires.
- The upper part of said wire or wires may be rivetted or connected to any suitable
head or top part of the stopper for instance a flanged disc or device adapted to receive
and hold thereon any suitable compressible or packing washer such for instance as an
ordinary rubber washer or collar while this disc or device is provided (either integral
therewith or attached thereto) with a suitable milled head or milled edge or with a'
loop knob or wings or other suitable means by which to grip the stopper and screw
up or.unscrew same.
For instance the male screw part the disc part carrying the elastic washer and the
winged head or grip may be all securely rivetted together.
or
In order to prevent the liquid or other contents of the bottle etc. from having any
corrosive action upon or suffering any injurious effect from said metallic stopper -I
form the male screw other part thereof of any suitable non-corrosive metal or I
may provide same with a coating such as vulcanite or I may coat or plate same with
tin, nickel, or other suitable metal by electro-deposition or otherwise.

for Bottles, Jars, or other Vessels.
I, HERBERT MONTGOMERY EDWARDS, of 37, Queen's Road, Brownswood Park, London,
Warehouseman, 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 has for its object improvements in or relating to the construction of
screw stoppers for bottles jars or other vessels and is as follows:
According to the present invention the screw thread or male screw part of an
internal or male stopper is of a skeleton form advantageously made of a piece of
spirally twisted rod or wire the shape in cross section or size or gauge of said rod or
wire being such as to correspond or fit more or less accurately-or otherwise suitably
fit the spiral groove or channel forming the female screw thread (in the neck or
opening of the bottle, jar, etc.) adapted to receive said male screw.
Or said skeleton male screw may be formed double or from a doubled wire or from
two or more wires.
The upper part of said wire or wires may be riveted or connected to any suitable
head or top part of the stopper for instance a flanged disc or device adapted to receive
and hold thereon any suitable compressible packing or washer etc. such for instance
as an ordinary rubber or cork washer or collar while this disc or device is provided
(either integral therewith or attached thereto) with a suitable milled head or milled
edge or with a loop, knob, wings, or other suitable means by which to grip the
stopper and screw in or unscrew same.
or
and
The male screw part, the disc part (carrying the elastic washer) and the head or
grip or part by which the stopper is turned, may be all securely riveted together.
In order to prevent the liquid or other contents of the bottle etc. from having any
corrosive action upon or suffering any injurious effect from said metallic stopper I
form the male screw other part or parts of said stopper of any suitable non-
corrosive metal or I may provide same with a coating such as vulcanite or I may coat
or plate same with tin, zinc, nickel or other suitable metal by electro-deposition or
otherwise for instance may galvanise the whole of the parts either before or after
(or both before and after) joining same together-such galvanising or electro-
deposition or plating or coating process serving to form a liquid-tight and gas-tight
joint at the point or points where the male screw part is fixed to the head or top
part of the stopper in cases where the former is riveted or secured to the latter by a
rivet or rivets or other suitable fastenings passing right through the said upper part
-the said galvanising or coating material serving to make a perfectly gas-tight joint
at such point or points.
Referring to the accompanying drawings:-
In Fig. 1 my improved male screw metallic stopper is shown with the male screw
part constructed of a single spirally twisted rod or wire a the upper end of which
latter is flattened and riveted by the rivet a¹ to the upwardly flanged disc b (having
washer or packing c on the flange thereof) and to the ring or handle d by which
latter the stopper is turned.
It will be obvious that the male screw part a may be riveted at two or more points
if desired and such rivet or rivets may be other than central in said stopper.
In Fig. 2 the male screw part a is riveted to a downwardly flanged disc 6 (having
washer c thereon) and to the disc or plate d having wings on said plate by which
means the said stopper can be turned.

page_text: In Fig. 3 the male screw part a is formed as a double spiral riveted to a down-
wardly flanged disc b and to the disc d this latter having a milled edge thereon (as
shown) by which means it is turned.
In Fig. 4 a single wire is shown with two rivets a¹ in the central part thereof each
end of the wire being spirally twisted to form the male screw part of the stopper as
shown said male screw part a being riveted (at the two points a¹) to the upwardly
flanged disc b and to the ends of the handle d by which latter the stopper is
turned.
The washer or packing c in each case when used may be of any suitable size
material etc. the parts a b and d being put together and finished as desired before
applying the washer.
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 :-
For stoppering a bottle jar or other vessel having a female screw thread within its
neck or opening:
1. A-stopper-having the male screw-part-thereof formed as-a-skeleton-from-a-rod
or wire (or wires) spirally twisted to correspond with the spiral of the female-serew
substantially in the manner and for the purposes-hereinbefore-described.
2. Constructing a metallic stopper of a spirally twisted rod or wire (or wires)
to form the male screw part as a skeleton, suitable head or top part adapted to
have said male serew part riveted or otherwise fixed thereon, and carrying any
suitable elastic-packing or washer thereon and means on said stopper by which to
turn same substantially in the manner and for the purposes-hereinbefore
described:
3. 1. Constructing a metallic stopper of a spirally twisted wire or wires such as a, a
flange disc such as b, a washer c on the flange of said disc and means such as a handle
wings or milled head d by which to turn said stopper substantially in the manner and
for the purposes hereinbefore described with reference to the drawings hereunto
annexed.
4.2. The improved construction of male screw stoppers having the several parts
combined arranged and operating substantially in the manner and for the purposes
hereinbefore described with reference to the drawings hereunto annexed.
5.3. The improved male screw stopper constructed substantially as herein before
set forth.
