COMPLETE SPECIFICATION.
An Improved Apparatus for the Preservation and Conveyance
of Milk.
I, ERNEST WIART, of 6 Faubourg Poissonière, Paris, France, Merchant,.
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 :-
The object of this application is to provide an improved milk-can specially
arranged for the conveyance of milk over long distances, and for its preservation,.
without altering in any way the essential qualities of the liquid. Many attempts
have been made to accomplish this object but they have hitherto failed for two.
reasons, namely, the rise in temperature which is liable to occur in summer-
weather and the agitation or shaking both of which seriously effect the condition.
and quality of the milk. To overcome this difficulty I have devised a milk-can
capable of containing the milk at a sufficiently low temperature, and for preventing
its being shaken which latter I accomplish by means of an airtight joint secured
by pressure.
I will now describe the invention with reference to the accompanying drawings,.
in which:
Fig. 1 shews a vertical section of my improved milk-can, and discloses the
central cylindrical vessel in which the ice is placed, and which I term an.
ice-holder.
Fig. 2 shews an elevation of the ice-holder detached.
Fig. 3 shews a plan view of the same.
Fig. 4 shews a vertical section of the same.
It will be seen that in order to obtain a sufficiently low temperature I place the
milk in the container 1 and insert the ice-holder H which I fill with ice,.
preferentially obtained from one block. The container I thus forms a reservoir
cooled from its centre for the refrigerating influence of the ice-holder. The upper
end of the ice-holder is enlarged and fits tightly into the throat of the container I.
I have somewhat enlarged the container to allow for the space occupied by the
ice-holder. The ice-holder itself is hermetically sealed by means of the cover B,.
furnished with cross-haudle C, between this cover and the contracted neck of the
cylinder I place a piece of felt or cloth c, which being wedged tightly by the
cover B ensures the tightness of the ice-holder. The cover is held tightly in place
by means of a cross-bar D, one end of which is attached to the handle of the
container by means of a chain and the other end is fastened to a lug a on the
container by a ring or wire of metal, or by a lead seal o or in any other suitable
way. The milk-container is thus securely fastened and if properly filled no.
churning action can take place, and both the quality and quantity of the milk are
secured. Two bow handles K are attached to the can for convenience of handling
and the bottom is strengthened by a hoop L in the usual way.
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:
. An improved receptacle for the conveyance of milk to long distances, and for
the preservation of same by means of a central ice-holder or refrigerator which.

page_text: maintains a sufficiently low temperature to prevent any deterioration of the
constituents of the milk: said ice-holder being fixed hermetically under pressure
inside the throat of the milk-container, as herein described and set forth.
Dated this 5th day of March 1897.
