Improvements in Stoppers for the Capillary Outlet Orifices of
Vessels Containing Volatile Liquids.
I, JOHN IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Consulting Engineer and Chartered Patent Agent, do hereby
declare the nature of this invention to be as follows:-
This invention relates to stoppers for the capillary outlet orifices of vessels
containing volatile liquids such for instance, as chloride of ethyl, or of methyl, the
object of the invention being to facilitate the application of such fluids for
anesthetic and other medical operations. For this purpose, there is fixed on the
conoidal neck of the vessel a shell or capsule on one side of which is pivotted a
lever. The upper arm of the lever has seated in it a pad or piece of caoutchouc
or other elastic packing material which is pressed against the capillary orifice at
the mouth of the vessel by a spring acting on the lever. The lower arm of the
lever is adapted to receive the pressure of the hand, so that a person holding the
vessel, can, by pressure on the lever, open the capillary mouth of the vessel
allowing escape of a portion of its contents.
For many purposes it is convenient to make the vessel with its neck inclined to
its body. Instead of forming the capillary orifice in the neck of the vessel itself,
it may be formed in a cylindrical piece of glass or other suitable material which is
held with an elastic packing on the mouth of the vessel by a screw socket, and can
be removed to allow of the vessel being readily filled. Instead of one, there may
be several outlet orifices each closed as described.
Dated this 9th day of September 1895.

I, JOHN IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Consulting Engineer and Chartered Patent Agent, 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 for the capillary outlet orifices of vessels

object of the invention being to facilitate the application of such fluids for
anesthetic and other medical purposes.

page_text: Fig. 1 of the accompanying drawings is an elevation of a vessel with stopper
according to this invention.
Fig. 2 is a section of the upper part drawn to an enlarged scale.
Figs. 3 and 4 are corresponding views of a vessel with bent neck, the capillary
orifice being formed in a plug.
As shewn in the figures, there is fixed on the conoidal neck of the vessel a shell
or capsule A on one side of which is a bracket 6 having pivotted on it at a a lever B.
The upper arm C of the lever has seated in it a pad or piece d of caoutchouc or
other elastic packing material which is pressed against the capillary orifice at
the mouth of the vessel by a spring D acting on the lever B. The lower arm c
of the lever is adapted to receive the pressure of the hand, so that a person
holding the vessel, can, by pressure on the lever in the direction of the arrow a
open the capillary mouth of the vessel allowing escape of a portion of its
contents.
For many purposes it is convenient to make the vessel with its neck inclined to
its body as shewn in Figs. 3 and 4, and, instead of forming the capillary orifice at
in the neck of the vessel itself, it may be formed as shown in these figures in a
cylindrical plug a³ of glass or other suitable material which is held with an elastic
packing a on the mouth of the vessel in a socket a² screwed into a union sleeve a³
which is screwed on the capsule A'. This plug can be removed to allow of the
vessel being readily filled.
Instead of one, there may be several outlet orifices each close as described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. A stopper for the capillary orifice of a vessel containing volatile fluid,
consisting of an elastic pad fixed on a spring lever pivotted on a capsule which is
fixed on the neck of the vessel, substantially as described.
2. In combination with the capsule on which the lever is mounted, a screwed
union sleeve and socket holding a plug in which the capillary orifice is formed,
substantially as described.
Dated this 22nd day of May 1896.
