We, REGINALD LE NEVE FOSTER, Manager of the firm of F. C. Calvert and
Company, of Bradford, near Manchester, in the County of Lancaster, Manu-
facturing Chemists; and JOHN SIDNEY CROWLEY, of Belair, Paignton, in the
County of Devon, Gentleman, do hereby declare the nature of this invention to be
as follows:-
Our invention relates to improvements in corking or stoppering bottles for
poisons and the like and the object of our invention is to indicate or call attention
to the poisonous or dangerous nature of the contents of a bottle whenever any
person attempts to take out the cork or stopper.
We effect this object by providing the corks or stoppers of such bottles with
pointed. projections or serrations which without being so sharp as to puncture or
tear the skin are yet sufficiently sharp to attract attention and to prevent a poison
bottle being opened heedlessly."
Various modes of furnishing the corks or stoppers with projecting points may
be employed according to our invention. For example a metallic or other ferrule
disc ring cap or thumb piece provided with serrations or other sharp projections
may be secured to each cork; and in like manner points can be moulded cut or
otherwise formed on glass stoppers.
COMPLETE SPECIFICATION.
Improvements in Corking or Stoppering Bottles for Poisons and the
like.
We, REGINALD LE NEVE FOSTER, Manager of the firm of F. C. Calvert and
Company, of Bradford, near Manchester, in the County of Lancaster, Manu-
facturing Chemists, and JOHN SIDNEY CROWLEY, of Belair, Paignton, in the
County of Devon, Gentleman, 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 :-
Our invention relates to improvements in corking or stoppering bottles for
poisons and the like and the object of our invention is to indicate or call attention
to the poisonous or dangerous nature of the contents of a bottle whenever any
person attempts to take out the cork or stopper.
We effect this object by providing the corks or stoppers of such bottles with
pointed projections or serrations which without being so sharp as to puncture or
tear the skin are yet sufficiently sharp to attract attention and to prevent a poison
bottle being opened heedlessly.
Various modes of furnishing the corks or stoppers with projecting points may be
employed according to our invention. For example, a metallic or other ferrule
disc ring cap or thumb piece provided with serrations or other sharp projections
may be secured to each cork; and in like manner points can be moulded cut or
otherwise formed on glass stoppers.
On the accompanying sheet of drawings are shown several forms of safety corks
and stoppers made according to our invention; but we wish it to be clearly

page_text: understood that these forms are simply introduced as types to illustrate a few out
of the many modes in which our invention can be applied and we do not desire or
intend to confine ourselves to any particular form or shape of cork or stopper.
Figures 1 and 2 are a side view and plan respectively of a safety cork and
Figs. 3, 4 and 5 are detail views of the parts of the same.
In this case we employ a cork a recessed to receive the shank b¹ of a button b
which is preferably formed of wood, covered on the top with metal foil, but may be
of any suitable material. On the shank b¹ beneath the head of the button b is
placed a disc or washer c the periphery of which is provided with sharp projections
as shown best in Figs. 2 and 5. The shank b¹ is then placed in the recess in the
cork a and the parts are glued or otherwise secured together.
Figs. 6 and 7 are two views of a cork a to which is secured a flanged metal
ferrule & with sharp points or projections as shown.
Figs. 8 to 11 are side views and Figs. 8 to 11 plan views of four glass stoppers e
the thumb pieces of which have points e¹ moulded cut or otherwise formed upon
them.
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
A cork or stopper furnished with projections serrations or points substantially as
and for the purposes herein described with reference to the drawings annexed.
