do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved barrel or receptacle for the preservation and
transport of fresh meat, fish, and other provisions.
The articles to be preserved are placed in this barrel which is then closed by a
particular device enabling the barrel to be closed with the least possible loss of
space.
The tub thus closed is then completely filled with water under a pressure of five or
six atmospheres. In order to facilitate the egress of the air which still remains in the
interior after the self-closing device is applied, I employ a slightly bulging end upon.
which a force pump is screwed. The air accumulates at the upper part and escapes
through a lateral passage in the body of the pump. When this passage allows water
to escape the tub is full, the extremity of the air passage is then closed the operation
of the pump being continued, whereby the water is compressed. The pressure is
indicated by a monometer.
The pump can then be screwed from the bottom of the tub, and, owing to a small
valve whose casing is integral with the self closing device, the pressure is pre-
served. The pump is replaced by a plug, and the barrel or receptacle is ready for
transport.
The barrel is constituted of tinned or galvanized sheet steel which is rivetted and
lastly subjected to tinning. This double coating ensures the solidity and preservation
of the metal. The upper end of the barrel has an opening designed for the intro-
duction of meat or fish to be preserved.
The self-closing device comprises a plate of cast steel provided at its centre with an
internally screw-threaded projection which serves for fixing the force pump. At its
under side it carries a small valve casing pierced with holes, and in which is a

in the apparatus.
The self-closing device which at its lower side is of a concave shape designed to collect
the air contained in the barrel when finally being filled, has an exterior flange in which
is formed a deep groove wherein a band of indiarubber, cord, leather or the like is
located the said band being applied against a second flange.
The self-closing device is of rectangular or other suitable shape and of as large ી
size as possible. It is passed sideways through the opening in the end of the barrel
and then brought to its final position.
The said closing device is kept in its place by two plates, each of which has three
arms and which are connected with each other by handles. The extremities of the said
arms bear upon a flange on the end of the barrel. Thus in spite of the great pressure
the closing device can be applied and removed with facility."

page_text: Improvements relating to Barrels or Receptacles for the Preservation
and Transport of Meat, Fish, and other Substances.
I, PIERRE EMILE ESTABLIE, of 11 to 13 Quai de Valmy, Paris France, Contractor
do hereby declare the nature of the said 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 an improved barrel or receptacle for the preservation and
transport of fresh meat, fish and other provisions.
The articles to be preserved are placed in this barrel, which is then closed by a
particular device enabling the barrel to be closed with the least possible loss of space.
The barrel thus closed is then completely filled with water under a pressure of
five or six atmospheres.
In order to facilitate the egress of the air which still remains in the interior after
the self-closing device is applied I employ a slightly bulging end upon which a force
pump is screwed. The air accumulates at the upper part and passes through the
conduit of the pump whence it escapes to the outside. A safety valve is arranged
so as to be lifted when the desired pressure is attained; at this moment the com-
pression of the water is discontinued; the pump is then unscrewed from the end
of the barrel, and, owing to a small valve whose casing is integral with the self-
closing device, the pressure is preserved. The pump is replaced by a screw plug and
the barrel or receptacle is ready for transport.
The barrel is constituted of tinned or galvanized sheet steel which is rivetted and
lastly subjected to fresh tinning; which coating ensures the solidity of the joint and
the preservation of the metal; this casing is provided with two ends of cast steel.
The upper has an opening designed for the introduction of meat or fish to be
preserved, and which is closed by means of the self closing device.
The self-closing device comprises a plate of cast steel provided at its centre with
an internally screw threaded projection which serves for fixing the force pump. At
its underside it carries a small valve casing pierced with holes, and in which is a
small ball valve which has for its object to oppose the egress of the compressed water
in the barrel.
The self-closing device which at its lower side is of a concave shape designed to
collect. the air contained in the barrel when the same is finally filled, has an exterior
flange in which is formed a deep groove wherein a band of india rubber, cord,
leather or the like is located, the said band being applied against a second flange on
the end of the barrel.
The self-closing device is of rectangular or other suitable shape and of as large a
size as possible. It is passed sideways through the opening in the end of the barrel
and then brought to its final position. The said closing device is kept in its place by
two plates each of which has three arms and which are connected with each other by
handles. The extremities of the said arms bear upon a flange on the end of the
barrel. Thus, in spite of the great pressure, the closing device can be applied and
removed with facility.

is introduced is of special construction, in order to enable the pressure of the barrel
to be gradually diminished prior to opening it for its discharge.

Like letters of reference indicate corresponding parts in all the figures.
The casing A of the barrel of galvanized or tinned steel or other suitable material
is bent and rivetted to two end pieces B and C. The upper end piece has a
rectangular opening closed by the self-closing device G and is provided with a flange D
against which is pressed the packing material E of the latter; this packing material
which is contained in a somewhat deep groove penetrates into the intermediate spaces
between the threads a, a provided in the lower side of the flange D on the upper end
piece C and ensures a perfectly tight joint between the latter and the closing device.
Upon the self closing device G are pivotted two plates H H the arms of which
are connected by handles II which serve for the operation and the removal of the
device. By causing the plates H H to turn upon their fixed points J, their extremities
are disengaged from the flange of the end piece D and the self-closing device can
be removed by moving it a little sideways. The reverse operation is performed in
order to close the barrel.
The system formed by the self-closing device Gand the end piece C is slightly
concave as shown in figure 1. At the top of this concavity is an opening wherein the
the casing K that contains the ball L is fixed. This casing is pierced with holes to
let the water under pressure pass and at its upper part with holes allowing the egress
of the air which collects in the upper part of the barrel above this casing is screwed
the force pump represented on a larger scale in two vertical sections in figures 5 to 8.
It comprises a casing of sheet metal, in which is located the pump body Q
wherein a plunger piston R moves being operated by a hand lever S.
The water which is poured into the casing O penetrates at the bottom of this casing
through the holes & provided in the plate T that carries the pump. It is then drawn
through the pipe c and forced through the passages d e f to the valve casing K. which
communicates with the interior of the barrel.
The water passing into the barrel compresses the air which has accumulated at the
upper part; this air passing through the upper holes of the valve casing K rises
through the water through the passage in the centre then leaves through the casing
of the safety valve g passing through the passage h which extends from the central
passage in the said casing.
When the opening i in the casing of the safety valve figure 9 allows only water to
pass the pressure is reached in the barrel, and the latter no longer contains air. The
compression is then discontinued, the ball valve L rises to its seat at the upper part
of the casing K, and opposes the
egress
of water.
The pressure, for which the tension of the spring k of the safety valve must be
regulated, is moreover indicated and controlled by means of a gauge m secured upon
the end piece C of the barrel A. This gauge, with a central pipe, is placed flat upon
the end piece C so as not to extend beyond the upper edge of the barrel (see figure 2
and 3). A second gauge can be secured at V upon the plate T of the pump. It
would communicate through the passage n with the central passage f.
The compression being terminated the pump is unscrewed and the opening o in the
self closing device is closed by means of the plug p represented in figure 4.

page_text: This plug, threaded on the outside presents at its interior screw threads with
which engages a screw 7 which I call a discharge screw for the following reason.
With a view to obviate the inconveniences that result from the sudden opening of
the barrel by the retreat of the self closing device, which would cause an instan-
taneous reduction of pressure that would result in damage to the provisions contained
in the barrel, or would give them a disagreeable appearance, it is necessary before
opening the barrel to gradually reduce the pressure in its interior in order to bring
it very slowly to zero.
For this purpose, after having unscrewed the plug p, the screw q is turned in order.
to cause it to pass a little from its place, the plug p is then put back in its place.
The screw which is thus in front of the plug passes into the valve casing K and
presses upon the ball L so as to force it to leave its seat in the casing K to which it
was applied.
The water under pressure in the interior of the barrel then passes through the
orifice and oozes through between the external threads of the plug and the internal
threads of the nut, thereby enabling the pressure to be gradually reduced. The
play which however small always exists between the screw and its nut is sufficient
to allow the passage of the small quantity of water that tends to leave under the
action of the compression in the barrel.
The pressure having been suitably diminished, the self closing device can be
withdrawn with the greatest facility.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
In a barrel designed for the preservation and transport of meat, fish and other
provisions,
First. The special construction of the said barrel with a somewhat bulging end
piece in order that the said barrel shall permit of being completely filled, and in
order that the air which collects at the upper part can be easily expelled therefrom.
Second. The closing of the barrel after its filling by means of a self-closing
device arranged as described, which can be 'conveniently slid into the interior of the
end piece although the barrel is filled, this self-closing devico being secured in place
by means of a system of pivoting exterior cross-bars which bear upon the end piece,
these cross-bars being connected together by rods, forming handles; the tightness of
the joint being moreover ensured by indiarubber, leather or other similar packing
material arranged in a groove in the plate of the self-closing device.
Third. With the object of drawing the air which collects at the centre of the end
piece provided with the self-closing device, and of forcing under pressure a certain
quantity of water to replace this air, the arrangement, in the centre of the self-
closing device, of a pump provided with a safety valve in order to limit the pressure
to the desired degree.
Fourth. The construction of the barrel of tinned or galvanized sheet metal, the
rivetted barrel being again passed into the tinning bath, for ensuring the preserva-
tion of this barrel and the tightness of the joints of its several parts.
Fifth. The arrangement of the plug having a discharge screw, in order to enable
the pressure to be gradually reduced at the moment when the full barrel is to be
opened, as hereinbefore described and represented.
