Improvements in Bottle Stoppers.
I, RUPERT ROBINSON, of 11, Ashbridge Road, Leytonstone, in the County of
Essex, Director, do hereby declare the nature of this invention to be as follows:-
My invention relates to bottle stoppers and has for its object to provide a
stopper having a handle of such shape that it can be readily engaged by the
bottling machine for the purpose of screwing in the stopper or grasped by the
hand when it is desired to withdraw the same.
Screw stoppers as at present manufactured are provided with milled heads of
various designs and one on the market has a flattened projecting portion which
has on either side of it a recess enabling the stopper to be very firmly grasped.
My improved bottle stopper differs. from these in the shape of the head which
according to my invention is formed at the top like a wing nut, that is to say,
substantially heart shape in cross section: the sides of the head are preferably
made concave so that a firm grip is afforded for the fingers of the operator.
whilst unscrewing the stopper. The under part of the stopper is made of the
ordinary shape and is of course varied to fit the various kinds of bottles with
which it is intended to be used.
.
My improved bottle stopper can be made of any material suitable for the
purpose such as vulcanite or other hard composition, and may be provided with
a fillet or groove for the reception of a packing ring if desired.

I, RUPERT ROBINSON, of 11, Ashbridge Road, Leytonstone, in the County of
Essex, Director, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to bottle stoppers and has for its object to provide a
stopper having a handle of such shape that it can be readily engaged by the
bottling machine or by hand for the purpose of screwing in the stopper or
grasped by the hand when it is desired to withdraw the same.
Screw stoppers as at present manufactured are provided with heads of
various designs and one on the market has a flattened projecting portion which

page_text: has on either side of it a recess enabling the stopper to be grasped by the
machine. My improved bottle stopper differs from these in the shape of the
head which according to my invention is formed at the top like a wing nut,
that is to say, substantially heart-shaped in cross section, the sides, of the head
are preferably made concave so that a firm grip is afforded the hand or machine
for screwing up and for the thumb and fingers of the operator. whilst unscrewing
the stopper. The under part of the stopper is made of the ordinary threaded
shape and of course may be varied to fit the different kinds of bottles with
which it may be intended to be used.
In the accompanying drawings:
Figure 1 is a front elevation of a bottle stopper constructed according to my
invention.
Figure 2a side elevation of the same.
The stopper is provided with the ordinary screw portion A adapted to enter
the neck of the bottle and a head B substantially heart-shaped as clearly
shewn in Figure 1.
From Figure 2 it will be seen that the sides of the head are made concave,.
I do not however restrict myself to this precise detail as stoppers with flat
sides are also included in my invention and whether flat or concave, with or
without a recess on either or both sides of the head as desired.
My improved bottle stopper can be made of any material suitable for the
purpose such as vulcanite or other hard composition, and may be provided with
a fillet or groove for the reception of a packing ring if desired.
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-
-
A bottle stopper provided with a head in the form of a wing nut or substantially
heart-shaped and concave or not at the sides, substantially as described.
