COMPLETE SPECIFICATION.
An Improved Stopper for Stoppering Bottles and other like Vessels.
We WILLIAM HAZLEHURST and EDWARD HAZLEHURST both of 22 St. Thomas
Street (North) Oldham both in the County of Lancaster Pattern Maker and Brewer's
Traveller respectively 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 stoppers externally applied to bottles and other like vessels.
This improvement has particular reference to a stopper being the subject of prior
Letters Patent granted to William Hazlehurst one of the inventors herein, being
numbered 10,072 A.D. 1886.
In the specification and the drawings thereto annexed of the aforesaid Patent a
stopper is therein fully described and illustrated. It will be observed on referring to
the said specification and drawings that between the cover and the rim of the bottle is
interposed a lining or seating of rubber or other flexible material; the seating and the
cover being an integral part. In practice it is found that when the cover is partly
rotated about its axis, in either direction for the purpose of applying or relieving from
pressure the cover, accordingly as may be desired to effectually stopper or unstopper
the vessel as the case may be, that from the fact of the adherence of the seating to the
surface of the rim of the vessel when under the influence of pressure that a resistance
is offered to the motion of the cover, such an occurrence presenting difficulty to the
operator to manipulate and in many cases has a tendency to resist an effectual closure
of the vessel.
Our improvement has for its object to remedy the defect herein before stated.
In order that our invention may be clearly understood we have reference to the
accompanying sheet of drawings, in which like letters of reference indicate like parts
throughout the figures therein shown.

page_text: Fig. 4 is a plan showing the position of the cover when the opening of the bottle is
to be effectually closed, or the stopper pressed tightly on to the rim of the vessel.
Fig. 5 is a sectional view of the rim of a bottle, and the stopper, showing a position
of the stopper when the opening of the bottle is to be uncovered.
Fig. 6 represents the clip.
Fig. 7 represents a hollow circular cover, without seating.
Fig. 8 represents a hollow circular piece in section which we term the shell, and
which is adapted to fit into the cavity of the cover.
Fig. 9 represents a circular rubber or other flexible piece in section, which is concave
at its lower side and is adapted to fit into the cavity of the shell and to seat on the rim
of the bottle.
Between the cover A and the rim B of the bottle or vessel, we interpose a shell C of
metal or other suitable material having a lining or seating D of rubber or other suitable
flexible material, the shell C is loosely fitted into the cavity of the hollow cover A, the
cover A being (when operated upon) free to rotate (partly) in either direction
independently of the shell C, during such motion the said shell remains in a stationary
position upon the surface of the rim B of the vessel, which rim is of spherical form,
being preferably of this form so that when the stopper is caused to assume various
positions or assume a position in relation to the rim B as shewn in Fig. 5, that the
seating D shall be in close contact with the surface thereof, and shall move freely
about its surface and the axis of the clip E when the cover is in such a position with
relation to the clip as is indicated in Fig. 3 which figure represents the elevated inclined
pieces F and G disengaged from the underside of the clip E. Fig. 4 shows the inclined
pieces passed under the clip thus the cover A with the seating D is pressed tightly
upon the rim of the vessel. The cover A being free to move about its axis independently
of the shell C allows the same to be easily turned by the operator obviating the binding
action of the seating D upon the rim B when so turned, which is the object of
this our invention.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is
1. In a stopper for stoppering bottles and other like hollow vessels the use and
application of a loosely fitted shell forming a component part of the stopper having a
seating of flexible material which shell shall be adapted to remain stationary on the
vessel whilst its component is free to be turned about its axis or have an independent
motion as and for the purposes herein fully set forth.
2. The hollow shell C having fitted into its cavity the flexible material D which is
adapted to seat in a spherical surface substantially as and for the purposes herein fully
set forth.
3. The combination of the hollow shell having a flexible seating D with a cover A
and clip E substantially as and for the purposes herein fully set forth and described in
the annexed drawings.
4. The combination of the cover A the clip E the shell C and its seating D with a
spherically shaped rim B substantially as and for the purposes herein fully set forth and
described in the annexed drawings.
Dated this 10th day of December 1887.
