Improvements in and relating to Cocks and Valves for Bottles
and other Receptacles.
I, Doctor JULES BENGUE, of 2 Rue Caulaincourt, Paris, in the Republic of
France, Chemist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a simple contrivance serving to render the ordinary
centre pointed cock, the rod of which is actuated by rotation and from outside,
properly tight fitting in all cases, without great exactness in its construction and
mounting being required.
For this purpose I make the conical point of the centre movable upon its guide
and actuating rod. In consequence of this movability, this conical point will
automatically, on closing the cock, place itself exactly into the axis of its seat and
the concentricity and consequently the tightness will be absolutely obtained in all
cases.
The centre is arranged with sufficient play in a cavity provided in its guide rod
or valve stem of the cock or valve, and it is connected to this rod by means of a
pin traversing the same with sufficient play.
My cock or valve comprises a case which is fixed on the bottle or receiver and a
valve stem which is screwed and unscrewed in this case and actuates in its
movements the valve or movable centre point.
In the arrangement of the lateral cock the casing communicates with the
receiver through a hole of which one branch is vertical and the other horizontal,
and with the outside through a capillary hole provided in a glass rod fixed in the
metallic joint, which latter is screwed upon the tubular piece of the said casing.
In the lower hollowed part of the rod cotton is placed so as to form a filter, and
an indiarubber washer, insures the tight closure around the said rod. The casing
is moreover provided with a horizontal tubular connection, in which the valve stem
is displaced when the lever is acted upon from outside.
The movable centre point is a piece of steel or other suitable metal, the head of
which is perfectly conical and the tail of which is pierced with a transverse hole.
A cylindrical hollow is arranged in the valve stem at its extremity; the
tail of the centre point is located therein with a sufficient play, and a pin of a
smaller diameter than that of the hole connects the centre point to the valve
stem in such a manner as to leave to this centre point sufficient liberty so as to
always place itself concentrically to the horizontal hole when bearing upon its seat
with its conical surface. The joint around the piston is formed by an indiarubber
washer compressed by a socket connected to and mounted upon the valve stem
without friction and screwed into the tubular piece.
In the arrangement of the vertical cock the casing is simply perforated in a
vertical direction.
The chamber is provided with internal screw threads of two different diameters
so as to receive the screw threaded valve stem and the socket which presses upon
the washer and forms a joint around the valve stem or rod. This valve stem or
rod is perforated all along its longitudinal axis to afford a passage for the liquid, and
two small side orifices provided above the conical head of the centre point produce
a communication of the central channel of this rod with the chamber of the case.

page_text: The connection of the rod and of the centre point is identical to that described for
the lateral cock. Upon the valve stem rod is keyed at a considerable height a
small milled hand wheel which permits of easily turning this rod or valve stem for
opening or closing the cock.
The upper part of the piston is provided with screw thread so as to receive, an
atomizing nozzle or one or more straight or curved nozzles, as the case may be.
I may apply my cock or valve with movable centre point to all kinds of bottles,
receivers or conduits required to be carefully and efficiently closed. I particularly
claim the exclusive right of applying my cock or valve for allowing of an easy
employment of volatile liquids for medical purposes or for domestic and industrial
use, such as ethyl-chloride, methyl-chloride and the like.
Finally I may vary the form, material and dimensions of the different parts of
my cock or valve, connect the movable centre point to its guide rod in any
appropriate manner different to that indicated and arrange the whole device in
any suitable way according to the particular application.

Improvements in and relating to Cocks and Valves for Bottles
and other Receptacles.
I, Dr. JULES BENGUE, of 2 Rue Caulaincourt, Paris, in the Republic of France,
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 various improvements in the closing of receptacles
designed to preserve and project more or less volatile liquids, these improvements
consisting substantially in the employment of a cock or valve with a movable centre
piece or conical valve ensuring perfect and unlimited tightness to these apparatus,
in combination with devices for the outlet of this liquid, either as a capillary jet or
in the form of vapours obtained by atomizing.
I first render the cock or valve with the ordinary centre piece, which is actuated
by rotation and from the outside, thoroughly tight in all cases without requiring
great accuracy in its construction and in its mounting. For this purpose I render
the conical centre piece of the spindle movable upon its guide and operating rod.
By reason of this movableness the said conical centre piece will, in the closing of
the cock or valve, be placed exactly in the axis of its seat, and the concentricity
and therefore the tightness will be absolute in all cases.
The centre piece is placed with play in a cavity of its guide rod or piston of
the cock or valve, and it is united to this rod by means of a pin which traverses it
with play.
In the accompanying drawings I have represented two bottles for volatile
liquids, permitting these liquids to be projected either as a capillary jet or in
the form of atomized liquid or vapour, these bottles embodying the chief features
of my invention.
Figure 1 is an exterior view of a bottle provided with a lateral cock or valve
having a movable centre piece, with a special connection for the outlet of the liquid
as a capillary jet.
Figure 2 is a vertical section to an enlarged scale of the lateral cock or valve
furnished with its connection having a capillary hole.

page_text: Figure 3 is an exterior view, partly in section, of the cock or valve piston or rod
for guiding the movable centre piece for the lateral cock or valve.
Figure 4 is an exterior view of a bottle provided with a vertical cock or valve
having a movable centre piece with an atomizing nozzle.
Figure 5 is a longitudinal section of the atomizing nozzle.
Figure 6 is a vertical section of the cock or valve piston or rod for guiding the
movable centre piece for the vertical cock or valve.
Figure 7 is a perspective view showing how I may operate the vertical cock or
valve with the same hand which holds the bottle.
My cock or valve comprises a box a which is fixed upon the bottle or recep-
tacle F, and a piston p which is screwed into this box and unscrewed therefrom and
operates in its movements the movable valve or centre piece p¹.
In the arrangement of the lateral cock or valve (Figures 1 to 3) the box a
communicates with the bottle F through a hole b, one of the branches of which is
vertical and the other horizontal, and with the outside through a capillary hole o
formed in a glass rod q fixed in a metallic connectioun which is in its turn screwed
upon the tubular part m of the box.
The capillary hole o of a certain diameter pierced in the glass rod q is widened
at the lower part so as to form two small cavities or funnels, one of which o¹,
remains empty and serves as a reservoir to obviate interruptions in the jet, whilst
the other, o, is filled with cotton for filtering the liquid and preventing any
obstruction of the capillary hole.
A rubber washers pressed between the tubular part m and the connection n
ensures tightness round the rod q.
The box a presents moreover a horizontal tubular part a¹ in which the piston p
is displaced when I act from the outside upon the lever f. The movable centre
piece is made of steel or other suitable metal, the head pl of which is perfectly
conical, and the tail-piece p² of which is pierced with a transverse hole g.
A cylindrical cavity is reserved in the piston p at its extremity; the tail-piece p
of the point is located therein with play, and a pin 1 made of a smaller diameter
than that of the hole g, connects the centre piece to the piston while affording
this point sufficient freedom for enabling it to be always placed concentrically
to the horizontal hole when it is caused to bear upon its seat b¹ by the conical
surface.
The joint is made round the piston p by a rubber washer compressed by a
gland slid without friction upon the rod of the piston and screwed into the tubular
part a'.
For projecting the liquid in the form of vapours I replace the connection n by
an atomizing nozzle x (Figure 5). These nozzles which are interchangeable, may
at will be curved or straight. In the arrangement of the vertical cock or valve
(Figures 4 to 7) the box a fixed upon the bottle F is simply pierced in a vertical
direction. The chamber is interiorly screw threaded at two different diameters for
receiving the screw threaded piston p and the gland which compresses the
washer t and makes a joint round the rod of this piston. This rod of the piston is
pierced in its axis throughout its length for the passage of the liquid, and two small
lateral orifices u u placed above the conical head of the point set the central channel
of this rod in communication with the chamber in the box a.
The union of the rod and centre piece is similar to that described for the
lateral cock or valve. Upon the rod of the piston is keyed at a suitable height a
small milled wheel v which enables this piston to be easily turned for opening or
closing the cock or valve. The same hand which holds the bottle may effect its
movements, for which purpose it is sufficient to take the wheel v between the thumb
and fore finger, as clearly shown in Figure 7.
The upper part of the piston is screw threaded so as to receive according to
circumstances either an atomizing nozzle projecting the liquid so to speak in a
vaporized state (Figure 4), or else a connection with a glass rod having a capillary
hole for the outlet of the liquid in the form of a capillary jet.

page_text: I reserve the right to apply my cock or valve with a movable centre piece to any
bottles, receptacles or conduits for which absolute tightness is indispensable. In
particular I may employ my cock or valve for permitting the ready use, in medicine
and for domestic and industrial purposes, of volatile liquids such as ethyl chloride,
methyl chloride and the like, and this in combination with the above described
devices for the outlet of these liquids as a capillary jet or as an atomized jet.
Lastly I may vary the forms, materials an1 di nensions of the various parts of
my cock or valve, unite the movable centre piece to its guide rod in any appropriate
manner other than that set forth, and to arrange the whole in any suitable manner
according to the special applications.
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 1
claim is :-
First. An improved closing device for receptacles designed to preserve and
project more or less volatile liquids, this closing device comprising substantially a
