PROVISIONAL SPECIFICATION.
An Improved Appliance for Inserting and Removing Screw and like.
Bottle or other Stoppers.
I, CHARLES EMILIUS SCHROEDER, Agent, of 98, Park Road, in the City and
County of Newcastle-on-Tyne, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an appliance for inserting and removing screw and
like bottle or other stoppers, the object being to provide an appliance that will
be both durable and cheap to produce.
An appliance, according to my invention, consists of an outer hollow part of
unyielding or rigid material and an inner hollow part of resilient or yielding
material, the latter being held within the former by a series of integral peri-
pheral ribs, studs or projections thereon engaging corresponding recesses or
grooves in the outer part, or vice versa. The outer part may be of wood, vulcanite
or other suitable materal shaped or otherwise adapted for convenient operation,
while the resilient material may be rubber, leather or other similar substance.
For use, the appliance is placed over the stopper with the resilient portion
surrounding and gripping same so that on turning the appliance the stopper
can be either inserted or withdrawn.

An Improved Appliance for Inserting and Removing Screw and like
Bottle or other Stoppers.
I, CHARLES EMILIUS SCHROEDER, Agent, of 98, Park Road, in the City and
County of Newcastle-on-Tyne, 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 relates to an appliance for inserting and removing screw and
like bottle or other stoppers, the object being to provide an appliance that will
be both durable, and cheap to produce.
An appliance made according to my invention is illustrated in the accom-
panying drawings, whereof Fig. 1 is a front elevation, and Fig. 2 is a cross
section on the line Z-Z in the previous figure.
The appliance consists of an outer hollow part A of unyielding or rigid

page_text: material, and an inner hollow part B of resilient or yielding material, the latter
being held within the former by a series of integral peripheral ribs, studs or pro-
jections b, b, b, 7 thereon engaging corresponding recesses or grooves a, a, a, a
in the outer part A.
As will be obvious, the location of the ribs b, b, b, b and recesses a, a, a, a
may be transposed, that is to say, the ribs may be formed on the outer part A,
and the recesses in the inner part B; but I prefer the arrangement exemplified
as I find it answers best.
The outer part A may be of wood, vulcanite or other suitable material shaped
or otherwise adapted for convenient operation, while the resilient material con-
stituting the part B may be of rubber, leather or other similar or appropriate
substance.
The appliance may be either hand or machine operated. The example illus-
trated is suitable for the former use, though of course the shape of the part A
may be varied to meet particular wishes; for instance, instead of being square
with a flat top, it may be made semi-spherical. In adapting the appliance for
machine use, the part A will be furnished with a boss or like part to receive and
be fixed to the usual revoluble spindle, thus replacing the customary clutch or
chuck.
The part B is best tapered, as represented, from the outer to the inner end,
for, in this way, the grip on the stopper is ensured.
In hand stoppering, the stopper is slackly fitted in the bottle before tightening,
while in machine stoppering the stopper is held in the clutch or chuck; and in
the use of my appliance, in the former case, the appliance is placed over the
stopper with the resilient portion B surrounding and gripping same, whereas,
in the other application, the stopper is pushed into the cavity of the part B
where it is held by the resiliency; but in both cases, on turning the appliance,
the stopper is either inserted into the required position, or withdrawn, depending
on the direction of rotation.
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. An appliance for inserting and removing screw and like bottle or other
stoppers consisting of an outer hollow part of unyielding or rigid material, and
an inner hollow part of resilient or yielding material, the two parts being
arranged and adapted for use, substantially as described.
2. An appliance for inserting and removing screw and like bottle or other
stoppers, constructed, and arranged or adapted for use, substantially as described
in reference to the accompanying drawings.
