Improvements in the Method of Closing and in the Construction of
Receptacles for the Reception of Chloride of Ethyl or Methyl or
other similar Liquid.
I JOHN WILLIAM MACKENZIE of the Firm of Wheatley and Mackenzie,
Engineers and Patent Agents of 40 Chancery Lane in the County of London, do
hereby declare the nature of this invention,- -a communication to me from Dr.
Jules Bengué of 2 Rue Colain Court, Paris, in the Republic of France, and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
This invention for improvements in the method of closing and in the construction
of receptacles for the reception of chloride of ethyl or methyl or other similar
liquid, has for its object to provide a receptacle assuring the indefinite preservation
of chloride of ethyl or methyl or similar volatile liquids and allowing of a fine jet
of this liquid to be obtained as desired. This apparatus permits of the convenient
and economic use of the liquid employed medically to produce local anesthysm.
In the accompanying sheet of illustrative drawings
:-
Figure 1 is an elevation of a receptacle with its stopper constructed according to
this invention and Figure 2 is a plan of the same.
Figure 3 is an elevation of the stopper and
Figure 4 is a central vertical section on the axis of the same.
The receptacle constructed of copper or other suitable metal in two or more
parts A A drawn, lapped and soldered together. The stopper closing this
receptacle forms the essential part of this invention. It is composed essentially
of a glass tube C with a capillary bore opened out into a cup shape C₁ at the
lower end, and this cup is covered by a cloth D of very fine mesh and acting as a
filter. On the tube is fitted a metallic covering which fits it exactly except at the
part opened out which is free. The upper part of this metallic piece is turned
away at I up to a small collar and screw threaded. On the threaded part is
screwed a metal capsule K in the bottom of which is placed a round piece of
rubber. The lower part of the metal covering is also turned away at F and screws
into the neck of the receptacle A A' which carries a corresponding screwed nozzle.
In the centre of the metal covering is a square part H to fit an ordinary spanner
or wrench and underneath this square is a ring G which rests on the seating formed
in the neck of the receptacle and by means of an interposed lead ring gives an
absolutely hermetical joint.
The receptacle being filled with liquid the stopper above described is firmly
screwed in place, the lead ring giving a hermetical joint to the neck; and the
capsule K being also screwed down completely closes the capillary bore E by
means of the rubber piece e.
When
To make use of the apparatus, the capsule K is unscrewed and the receptacle
inclined a capillary jet being obtained which is directed on the desired part.
the desired effect is obtained the capsule is replaced and the apparatus may be used
any number of times.
The filtering cloth D insures the regular action of the apparatus by keeping
back impurities which would obstruct the capillary bore. When the receptacle is
empty it may be again refilled. The apparatus may also be used as a perfume
spray.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. The construction and arrangement substantially as described of a stopper

page_text: allowing the absolute preservation and the fractional use in a very fine jet-due to
the capillary bore of the glass tube forming part of the stopper-of chloride of
ethyl or methyl or other volatile products contained in a metal receptacle which
can be refilled when empty and so last indefinitely.
2. In a stopper for receptacles for containing chloride of ethyl or methyl or
other volatile product the use of a glass tube with a capillary bore enlarged at its
lower end and covered with a filter cloth substantially as described for the purpose
.set forth.
Dated this 16th day of June 1893.
