PROVISIONAL SPECIFICATION.
Improvements in and connected with the Stoppers or Caps of Bottles
Containing Medicinal and other Liquids.
FREDERICK WILLIAM FLETCHER, Beauchamp Lodge, Enfield Middlesex
Manufacturing Chemist, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in the stoppers or caps of bottles con-
taining medicinal and other liquids, and its object is to provide the stopper or
cap with a contrivance by means of which the said liquids may be withdrawn from
the bottle and measured, thus rendering unnecessary a separate measuring instru-
ment or vessel.
The arrangement consists of a stopper or cap of any suitable material through
which passes a
graduated glass tube. The upper end of the tube is preferably
flanged in order the more securely to attach it to an elastic air chamber of any
convenient shape. The action of the arrangement is as follows:
The stopper or cap having been loosened, any air or liquid in the graduated
tube is expelled by compressing the elastic chamber. The lower part of the tube
is then immersed in the liquid, and the pressure on the air chamber gradually
released. The liquid will then rise in the graduated tube to any desired point,
where it will remain, and whence it can be transferred to another vessel by
removing the arrangement and once more compressing the air chamber.
Instead of an elastic air chamber the graduated tube may be provided with a
piston like a syringe.
If desired, the stopper or cap may be more securely fixed into or upon the
mouth of the bottle by means of a screw or other appropriate fastening.

COMPLETE SPECIFICATION.
Improvements in and connected with the Stoppers or Caps of Bottles
Containing Medicinal and other Liquids.
1, FREDERICK William FLETCHER of Beauchamp Lodge Enfield Middlesex,
Manufacturing Chemist 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 :-
My invention relates to improvements in the stoppers or caps of bottles con-
taining medicinal and other liquids, and its object is to provide the stopper or
cap with a contrivance by means of which the said liquids may be withdrawn from
the bottle and measured, thus rendering unnecessary a separate measuring instru-
ment or vessel. I have given to my invention the name of autometric stopper or
autometron. In the accompanying drawings A (Fig. 1) is a perforated stopper
formed of india rubber or other suitable material, through which passes a
graduated glass tube B of any convenient shape or size. The upper end of the
tube is preferably flanged in order the more securely to attach it to the elastic
air chamber C which may be spherical, as shown, or of any other convenient shape.
My invention is used as follows-The stopper A (Fig. 2) having been loosened,
any air or liquid in the graduated tube is expelled by compressing the elastic
air chamber C. The lower part of the tube is then iminersed in the liquid, and
the pressure on the air chamber gradually released.

page_text: The liquid will then rise in the graduated tube to any desired point, where it
will remain, and can then be transferred to another vessel by removing the
arrangement and once more compressing the air chamber.
Instead of an elastic air chamber, the graduated tube may be provided with a
piston like a syringe.
If desired, the stopper may be more securely fixed into the mouth of the bottle
by means of a screw or other appropriate fastening. Instead of a stopper fitting
into the mouth of the bottle, a cap D (Fig. 3.) made of any suitable material may
be substituted.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
.claim is-
A stopper or cap for bottles containing medicinal and other liquids, having a
contrivance attached by means of which the said liquids may be withdrawn and
measured without the aid of any other instrument or vessel, substantially in the
manner hereinbefore described and as illustrated by the accompanying drawings.
Dated this 20th day of January 1892.
