PROVISIONAL SPECIFICATION.
A Portable Receiver to Retain Volatile Liquids while Allowing of
the Escape of their Vapours.
WILLIAM HENRY BEACH 10, East Castle Street, Bridgnorth Shropshire Veterinary
Surgeon do hereby declare the nature of this invention to be as follows:-
My invention consists of a cylinder pierced at the top and bottom by tubes which
terminate near its centre charged with liquid less than half its capacity, the vapour
arising therefrom may be utilised without the liquid itself being spilt, notwithstanding
that the cylinder be in any position. I provide a suitable joint by which the top of
the cylinder can be removed for the purpose of charging, and I fix a piece of non-
conducting substance to the bottom through which the vapour may be passed to be
utilised for the production of light & heat or local or general anesthesia I provide a
suitable nozzle to the top to which tubes may be attached to pass a current of air
through the cylinder.

A Portable Receiver to Retain Volatile Liquids while Allowing of
the Escape of their Vapours.
I WILLIAM HENRY BEACH, of 25 East Castle Street, Bridgnorth in the County of
Salop, Veterinary Surgeon 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 a portable receiver for use in connection with
Dr. Paquelin's well known thermo-cauter, the purpose of the receiver being to
contain, and retain, the volatile liquid while permitting the carrying off of its vapor
in order to maintain the cauter at its proper state of incandescence.
Heretofore in using tho Paquelin thermo-cauter, the benzoline has been generally
contained in a bottle which it has been usual to suspend from the button hole of the
operator's coat, the bottle being connected by flexible tubes with the pneumatic bulb
on the one hand and with the thermo-cauter on the other.
The thermo-cauter is used both for human surgery and in veterinary practice and
in the latter case this means of holding the store of benzoline is apt to lead to
dangerous accidents as owing to a sudden movement of the operator in order to escape
injury by the animal under treatment or from other cause the bottle is liable to be
broken. Moreover the movements of the operator are cramped as should he assume
a stooping position the bottle is apt to be inverted, the benzoline is consequently
liable to choke the outlet tube leading to the cauter, extinguish the latter and escape
in the liquid state from the instrument.
The object of my invention is to provide a reservoir which forms an integral part
of the cauter itself and which may be held in any position without causing the grave
objections above referrel to.
Reference is to be had to the accompanying drawings forming part of this specifica-
tion wherein figure 1 is a central longitudinal section of my improved reservoir, as
applied to the Paquelin thermo-cauter and figure 2 is a modification. The same letters
of reference indicate like parts in both figures.
The Invention consists of a cylindrical inetal chamber A closed at the one end and
fitted at the other end with a screw-cap B. Axially into the opposite ends of this
cylinder project the inlet and outlet tubes C, D, these tubes being separated by a

page_text: sufficient interval to allow the air current to exercise its inductive action on the vapors
contained in the cylinder. E is the Paquelin thermo-cauter which being well known
needs no description. It is connected by a screw-joint with a metal cap F which is
connected with the closed end of the cylinder A only through the intervention of a
block G of ebony or other poor conductor of heat. The outer tube D communicates 5
with an orifice through said block and with the bore of the screw nozzle of the cap F
to which the cauter is screwed.
The receptacle A thus constitutes the handle of the cauter and is filled to so much
less than half its capacity that the benzoline cannot run out of the tube C, D, in
whatever position it may be held. The screw-cap B is provided with a nozzle for the
attachment of a flexible tube by which the inlet tube C is connected with the
pneumatic bulb H. Screw plugs (not shown) are provided for closing the inlet and
outlet orifices in the caps B, F, when the air pipe and cauter are disconnected fromi
the reservoir, for transport.
The cylinder, apart from the cauter and pneumatic apparatus, may also be used for
the purpose of administering a local anaesthetic. For example by closing the orifice
in cap B and attaching the tube of an enema to the orifice of cap F, the cylinder
previously charged with ether may be immersed in hot water for the purpose of
driving off the ether vapors through the enema tube to the point of application
required.
My Invention also comprises a modification of the above described apparatus for
the purposes of general anesthesia, which is illustrated in figure 2. It consists of a
glass or other bulb A intended to contain chloroform and having an air inlet tube C
and concentrically therewith, the outlet tube D, the latter being rather longer than
the former and both terminating at about equal distances from the centre of the bulb
and both being fixed in a cap B screwing on the neck of the bulb. Between the
tubes C and D is an annular air inlet and to the outlet tube D is connected a flexible
tube terminating in an inhalation mouth piece. When not in use the flexible tube is
detached and the inlet and outlet tubes closed by a screw-cap Z screwing on to the
neck of cap B.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;
1. The combination with a thermo-cauter of a cylindrical reservoir for volatile
liquid, said reservoir having inlet and outlet tubes projecting axially within it from
opposite ends and respectively in connection with the pneumatic bulb and with the
cauter, said reservoir forming the handle for the thermo-cauter, substantially as specified
2. The combination with a thermo-cauter of a cylindrical reservoir for volatile
liquids, said reservoir having air inlet and air and vapor outlet tubes projecting axially
within it from opposite ends and terminating within a short distance from each other
the said reservoir serving as the handle for the cauter and being connected theret
through a non-conducting block, substantially as specified.
3. The combination of the herein-described cylinder closed at one end and provided
with an inwardly-projecting outlet tube at the other end, with an enema for th
administration of a local anaesthetic, as described.
4. The combination with an inhalation mouth piece of a portable receiver to contai
anesthetic liquid, consisting of a glass bulb provided with concentric inlet and outle
tubes arranged substantially as described for the admission of air and for conveyin
the
where required.
