PROVISIONAL SPECIFICATION.
Improvements in Means or Receivers for the Preservation and
Application of Chloride of Ethyl and other Volatile Liquids, to
be employed principally in the Production of Cold.
I, BENJAMIN JOSEPH BARNARD MILLS of 23 Southampton Buildings in the
County of Middlesex Patent Agent do hereby declare the nature of this inven-
tion, (a communication to me from Messieurs Auguste Gilliard, Prosper Monnet
and Jean Marie Cartier of 8 Quai de Retz, Lyons, in the Republic of France
Manufacturers of Chemical Products), to be as follows, reference being had to the
accompanying drawings and to the figures and letters marked thereon:-
Hitherto chloride of ethyl has been delivered to commerce in small glass receivers
having capillary necks closed or sealed by a blow pipe, of which it was only
necessary to break the point to be enabled to project the liquid in a more or less
strong jet according to the heat communicated to it by the hand.
It is now proposed to produce receivers with metallic closure capable of being
opened and closed at will and consequently capable of containing a quantity of any
desired liquid, and of being again filled after having been emptied. These new
receivers may be used not only for chloride of ethyl but for any volatile liquid to
be projected in a jet or in vapour, by an elevation of temperature, which in
practice is furnished by the heat of the hand.
The accompanying drawing shows at Figures 1 and 4 external views of two
differently shaped receivers and at Figures 2 and 3 respectively a longitudinal
section and an external view of the metallic closing means drawn to an enlarged
scale.
The glass receiver A, which can be of any desired form and dimensions provided
it can be held in the hand, has its neck terminated by a capillary orifice.
Upon its neck is cemented or otherwise fixed a metallic neck B corresponding
with the external form of the neck of the receiver which can have a straight neck
as represented at Figure 1. or a bent neck as at Figure 4. This neck is covered
by a stopper C in the hollow of which is placed a disc b, of caoutchouc or other.

suitable means effecting the same object.

and will press the compressible disc 6 strongly against the orifice of the neck, so as
to close it hermetically.
This closing fastening means is known as a bayonet joint and is well known in
other applications, but it is desired to claim its special application to the particular
case above referred to, because of its simplicity and of the rapidity of closing
which cannot be otherwise obtained.

Improvements in Means or Receivers for the Preservation and
Application of Chloride of Ethyl and other Volatile Liquids, to
be employed principally in the Production of Cold.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings,, in the
County of Middlesex, Patent Agent, do hereby declare the nature of this inven-
tion, (a communication to me from Messrs. Auguste Gilliard, Prosper Monnet
and Jean Marie Cartier, of 8 Quai de Retz, Lyons, in the Republic of France
Manufacturers of Chemical Products), and in what manner the same is to be,
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying drawings and to the figures
and letters marked thereon :-
Hitherto chloride of ethyl has been delivered to commerce in small glass receivers
having capillary necks closed or sealed by a blow pipe, of which it was only
necessary to break the point to be enabled to project the liquid in a more or less
strong jet, according to the heat communicated to it by the hand.
It is now proposed to produce receivers with metallic closure capable of being
opened and closed at will and consequently capable of containing a quantity of any
desired liquid and of being again filled after having been emptied. These new
receivers may be used not only for chloride of ethyl but for any volatile liquid to
be projected in a jet or in vapour by an elevation of temperature, which in practice
is furnished by the heat of the hand.
The accompanying drawings show, at Figures 1 and 4, external views of two
differently shaped receivers and, at Figures 2 and 3, respectively a longitudinal
scetion and an external view of the metall; closing means drawn to an enlarged
scale.
The glass receiver A, which can be of any desired form and dimensions provided
it can be held in the hand, has its neck terminated by a capillary orifice. Upon its
neck is cemented or otherwise fixed a metallic neck B corresponding with the
external form of the neck of the receiver, which can have a straight neck as
represented at Figure 1, or a bent neck as at Figure 4. This neck is covered by a
stopper C, in the hollow of which may be placed, as described in my Provisional
Specification, a disc of caoutchouc or other suitable compressible material pressed
forward by a coiled spring, but, as shown in the accompanying drawings, it is
preferred to place a stopper b of caoutchouc or other elastic material in the hollow
of the stopper C.
The closing is maintained by a stud c fixed to the neck B and capable of entering
the slot d of the stopper until it enters the interior groove e, within which it can
engage by giving the stopper a partial turn. The caoutchouc stopper b, the length
of which is regulated to suit, will be then compressed and will press strongly
against the neck, the orifice of which it hermetically closes.
This closing fastening means is known as a bayonet joint and is well known in
other applications, but it is desired to claim its special application to the particular
case above referred to, because of its simplicity and of the rapidity of closing,
which cannot be otherwise obtained.
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 :-
1. The new or improved receiver or holder for containing and applying chloride
of ethyl and other volatile liquids principally for producing cold by evaporation of
the liquid projected, the said receiver or holder being of glass and having a
capillary orifice and being provided with a metallic closure fitting with a bayonet

page_text: catch and provided with a stopper for closing at will the capillary orifice in the
neck of the said receiver or holder, substantially as herein shown and described.
2. The new or improved receiver or holder for containing and applying chloride
of ethyl and other volatile liquids, substantially as herein shown and described and
for the purpose stated.
