Year: 1877

page_text: LETTERS PATENT to James Cooper, of Huddersfield, in the County of York,
Innkeeper, for the Invention of "IMPROVEMENTS IN BOTTLE STOPPERS, AND IN
APPARATUS CONNECTED THEREWITH."
Sealed the 9th November 1877, and dated the 29th August 1877.
PROVISIONAL SPECIFICATION left by the said James Cooper at the Office of
the Commissioners of Patents on the 29th August 1877.
JAMES COOPER, of Huddersfield, in the County of York, Innkeeper. "IMPROVE-
MENTS IN BOTTLE STOPPERS, AND IN APPARATUS CONNECTED THEREWITH."
This Invention relates to an improvement in bottle stoppers of the external class,
and the object of the Invention is to construct such as to be available and applicable
to bottles of ordinary form or shape of neck; the apparatus for securing and for
removing the stopper from the nozzle of the bottle being a combination of clasp or
holder disc, or a ball stopper, and a bow, blade, spiral, or other spring.
The construction is as follows:-One end of a blade or bow spring is secured to a
wire or other hinge piece attached to the neck of the bottle; the stopper consists of
a stud, disc, and india-rubber washer (or a ball of india-rubber) are attached to the
spring at such position that when the spring is compressed the disc (or ball) stopper
is within the neck of the bottle, the other or loose end of the spring is held by a
clasp or holding piece connected with the wire or hinge piece above referred to.
When the clasp is forced off the end of the spring the latter rebounds, withdrawing
the stopper, self-acting from the neck of the bottle.
In lieu of a blade or bow spring a spiral spring or springs may be attached to a
cross piece attached to the head of the stopper, and a clasp or holding piece is
described, or the spring may be applied between the hinge piece and the stopper, or
a bow or spiral spring may be applied beneath the disc.

"IMPROVE-
This Invention relates to an improvement in bottle stoppers of the external class,
and the object of the Invention is to construct such as to be available and applicable
to bottles of ordinary form or shape of neck; the apparatus for securing and for
removing the stopper from the nozzle of the bottle being a combination of clasp or
holder, disc, or a ball stopper, and a bow, blade, spiral, or other spring.
The construction is as follows:-One end of a blade or bow spring is secured to a
wire or other hinge piece attached to the neck of the bottle; the stopper consists of
a stud, disc, and india-rubber washer (or a ball of india-rubber) attached to the
spring at such position that when the spring is compressed the disc (or ball) stopper
is within the neck of the bottle; the other or loose end of the spring is held by a
clasp or holding piece connected with the wire or hinge piece above referred to.
When the clasp is forced off the end of the spring the latter rebounds, withdrawing
the stopper self-actingley from the neck of the bottle.
In lieu of a blade or bow spring a spiral spring or springs may be attached to a
cross piece,attached to the head of the stopper, and a clasp or holding piece as
described, or the spring, may be applied between the hinge piece and the stopper, or
a bow or spiral spring may be applied beneath the disc..
Such being the nature and object of this my said Invention, I will now proceed
to describe the same in detail, and in order that the Invention may be fully under-
stood I have hereunto annexed one Sheet of Drawings, and have marked the same
with figures and letters of reference, the same letter referring to the same part in
the several views or Figures.
At Fig. 1A is the blade or bow spring; B, the hinge piece; C, the disc stopper,
attached to the spring A when the disc is in position within the neck of the bottle;
it is there held by means of the clasp or holding piece D; the latter and the hinge
piece B are secured by the wires Ė, F. On the clasp or holding piece D being
released the rebound of the spring A self-actingley withdraws the stopper to the
position shewn by dotted lines.
Fig. 2 shews the application of an elastic ball to the spring A, in lieu of the
disc stopper described in connection with Fig. 1.
Fig. 3 shews the application of a spiral spring A in lieu of the blade or bow
spring.
Fig 4 shews the spiral spring A attached to the cross piece a, secured to the
stopper disc as described.
Fig. 5 shews blade spring A applied vertically.
Fig. 6 shews spring A released and stopper withdrawn.
Fig. 7; like view, shewing double wires E and F.
Fig. 8, another modification of vertical application of spring A.
In all cases the clasp or holding piece D may be tempered, so as to act as a spring,
that when the stopper, if pressed into the mouth of the bottle, the spring clasp or
holding piece will self-actingley engage with the catch of the part carrying the disc
or ball stopper.
Having thus fully described. the nature and particulars of this my said Invention,
together with the manner in which the same is to be performed, I would observe
that in order to fully illustrate and describe the Invention, I have shewn and
described parts which are not new, and I expressly limit and confine my Invention

page_text: to the application and use of a bow, blade, or spiral spring A, for the purpose
described and illustrated.
In witness whereof, I, the said James Cooper, have hereunto set my hand
and seal, this Twenty-sixth day of February, in the year of our Lord One
thousand eight hundred and seventy-eight.
