"IMPROVEMENTS IN AND RELATING TO VESSELS FOR CONTAINING AND

Southampton Buildings, London "IMPROVEMENTS IN AND RELATING TO VESSELS
FOR CONTAINING AND PRESERVING LIQUIDS." [A communication to him from
abroad by Augustin Jean Gay, of Paris, France.]
A liquid contained in a water-tight or hermetically closed vessel which it
completely fills will be preserved in good condition, but if some of this liquid is
withdrawn and air is admitted which has hitherto been necessary to permit the
flow of the liquid from the vessel, the remaining portion of the liquid is liable to
deterioration. This is always the result when the liquid is drawn off in small
quantities from time to time as it is required for use, thus leaving the vessel only
partially full for a considerable time and exposing the liquid therein to the action
of the air which enters the said vessel.
According to this invention I prevent the access of air to the liquid remaining in
the vessel, in the following manner, that is to say,
I provide means whereby in proportion as the liquid is drawn out the upper
surface thereof will be closed over and protected from the air in the open space
which has heretofore been invariably left between this surface and the upper part
of the vessel the object of my invention may be attained in several ways two of
which are represented in the accompanying drawing.
Referring to Figure 1 A represents a vessel which may be made of stone-ware,
metal, glass, porcelain or any other suitable material and is closed by a cover B.
A float or follower C rests upon the surface of the liquid and its periphery is

page_text: furnished with a band of india rubber D which prevents the egress of air to the
liquid, or instead of the said india-rubber band I may in some cases employ a thin
layer of olive oil. As the liquid is withdrawn through the tap R the level
descends but the float or follower C descends also and prevents the air above the
same from coming in contact with the liquid which is thus preserved in good
condition instead of being deteriorated as is always the case when the liquid is
exposed.
Referring now to Figure 2 A represents a wooden case or vessel closed by a
cover B. This vessel contains a bag E of india-rubber gutta percha, waterproof
fabric or other suitable thin flexible substance in which the liquid is contained. 1
This bag is so made that that the liquid as it enters the same distends it and thus as
the liquid is withdrawn through the tap R the said bag closes upon the reduced
volume of the said liquid and effects the same object as is effected by the float
shewn in Figure 1. The wooden case or vessel protects the flexible bag and
forms a convenient stand for the whole. It may be ornamented in any desirable 1
manner,

A communication to me from abroad
FOR CONTAINING AND PRESERVING LIQUIDS
by Augustin Jean Gay, of Paris, France
This invention relates to vessels from which liquids may be drawn without
allowing the air to come into contact therewith. Heretofore a liquid contained in
a water-tight or hermetically closed vessel completely filled, was preserved in good
condition; but if some of this liquid was withdrawn air was admitted to permit
the flow of the liquid from the vessel, the remaining portion of the liquid was
thereby liable to deterioration. This was always the result when the liquid was
drawn off in small quantities from time to time as it was required for use, leaving
the vessel only partially full for a considerable time and exposing the liquid therein
to the action of the air which entered the said vessel.
According to this invention I prevent the access of air to the liquid in the vessel,
in the following manner that is to say :--I provide means whereby in proportion
as the liquid is drawn out the upper surface thereof, will be closed over and
protected from the air in the open space which has heretofore been invariably left
between this surface and the upper part, of the vessel.
The object of the said invention may be attained in several ways two being
illustrated in the accompanying drawing in which
Figure 1 is a longitudinal vertical section of a vessel provided with a float and
Figure 2. a similar view of a vessel provided with a flexible bag.
Referring to Figure 1 A indicates a vessel which may be made of stone-ware,
metal, glass, porcelain, or any other suitable material and is closed by a cover B.
A float or follower C rests upon the surface of the liquid, and its periphery is
furnished with a band of india-rubber D which prevents the entrance of air to the
liquid.
Instead of the said india-rubber band I may in some cases employ a thin layer
of olive oil.
As the liquid is withdrawn through the tap R the level descends, but the flont
or follower C descends also and prevents the air above the same from coming in
contact with the liquid which is thus preserved in good condition instead of being
deteriorated as is the case when the liquid is exposed.
Referring to Figure 2, A indicates a wooden case or vessel closed by a cover B.
This vessel contains a bag E of india-rubber gutta-percha, waterproof fabric or
other suitable thin flexible substance in which the liquid is contained. This
bag is so made that the liquid, as it enters the samo, distends it, and thus as
the said liquid is withdrawn through the tap R the said bag closes upon the said
liquid and effects the same object as is effected by the flont shewn in Figure 1.
The wooden case or vessel protects the flexible bag and forms a convenient stand
for the whole. It may be ornamented in any desirable manner.
Having thus fully described the said invention as communicated to me by my
foreign Correspondent, and the manner of performing the saine, I wish it
understood that I claim
A vessel for containing liquid, having movable portions arranged therein in

page_text: such a manner that, as the said liquid is withdrawn, the said movable portions will
keep in contact with the liquid and prevent the access of air thereto, whereby the
said liquid is preserved.
In Witness whereof I the said William Robert Lake, have hereunto set my
hand and seal this Nineteenth day of June in the year of our Lord One
thousand eight hundred and eighty three.
