Improvements relating to Receptacles, such as Jugs, Pans, or the
like, employed for the Temporary Storage of Liquids, and to the
Lids or Coverings thereof.
L. EDWARD GREENFIELD, of St. Alban's Place, Islington Green, London, N.,
Gentleman, 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 :-
My invention relates, Firstly, to the improved construction of the lids or coverings
and necks of jugs, pans and the like employed for the temporary storage of liquids
by means of which I am enabled to dispense with the usual binge which serves as
the means of attachment of the lid to the jug, this hinge attachment being so quickly
subjected to decay either by corrosion or by the loosening of the rivets; my inven-
tion relates, Secondly, to the construction of said jugs, pans or the like with an
especial view to cooling, refrigerating and freezing the contents in summer, as also
for chilling, warming or scalding in winter.
In the annexed drawing Figures 1 to 4 illustrate the application of my improve-
ments to jugs and Figure 5 to a milk pan; they may also be adapted with equal
facility to other vessels.
Referring to the drawing,
Figure 1 is an elevational view of a jug having a sliding lid and hinged spout.
Figure 2 is a similar view, the lid being formed with a semi-circular orifice.
Figure 3 is a vertical section of a jug the lid of which is fitted with a hinged spout.
The jug is provided with an outer shell, the space intervening between the inner and
outer shell serving as a cooling or beating chamber as the case may be.
Figure 4 is an elevation of same.
Figure 5 is a vertical section of a milk pan or analogous vessel constructed with
a jacket or receptacle for containing a warming or cooling agent.
In carrying out the first part of my said invention I construct or form the month
of the jug A or other receptacle with a groove, channel or slot a in or on the
neck of the vessel, into which a properly formed lid B can slide, be retained, or
withdrawn at the will of the operator. In some cases it is preferable to form upon
the neck, or exterior thereto, a fillet or fillets, into which, or between which the
edge of the lid B can pass, a groove or channel may also be formed in the lid.
The vessel A may have a spout b, or, in place of lip or spout I may provide a
hole semi-circular or otherwise, or an expanding and receding lip may be provided.
The lid B, formed of earthenware, metal, or other suitable material may be complete
in itself, fitting neatly to the form or shape of the jug, thus retaining the temperature
of the liquid stored within it, or it may be provided with an orifice c. but
preferably in the best style and quality I construct it with a hinged lip d which,
in the act of pouring, is opened by the pressure of the liquids contained within
the jug.
In any of these forms the lid may be applied to ordinary jugs or vessels for coffee,
hot water, milk, beer and other liquids. If for milk, I cover the outer surface of
the jug with a surrounding lapping or envelope of felt or other suitable porous
material to serve as a cheap and efficient means for cooling by atmospheric
evaporation when the said surrounding jacket is moistened.
Under the second head of my invention I form the jug or other liquid receptacle
with outer sides or with an outer casing A', and, in some instances outer bottom,
thus forming as it were a shell of the real receptacle, or in other words, the receptacle
is duplex, being a jug within a jug, or other vessel, sustained by the rim or
depending therefrom or built upon the bottom. A jug or other vessel so constructed

page_text: is shown in Figures 3 and 4, and is designed for the purpose of the storage of
milk in summer, the outer vessel or the chamber formed between the two
shells A, A, being preferably filled with spring water, or packed with ice, keeping
the milk at a low temperature, and preventing the same from souring. In those
cases where it is desirable to raise the cream speedily upon the milk the object
may be readily attained by simply filling one of the compartments with boiling
water and the same method would be invaluable for retaining a medium temperature
of the milk in the depth of winter, thus keeping the quality from depreciating.
For use in dairies or upon the counters of shops, pans constructed upon the duplex
system Figure 5 would be extremely useful either in the hot days of summer or the
coldest days of winter for cooling or heating purposes.
In the case of vessels constructed solely for cooling purposes, milk receptacles
more especially, in one style I provide or construct the outer shell or walls of the
receptacle of porous earthenware, so that the cooling influence produced by evapora-
tion may be beneficially exercised upon the fluid when the outer chamber is supplied
with water.
These receptacles may be constructed of any suitable material and the outer and
inner vessel he of the same or diverse character. As a jug for beer, a supply of
boiling water in one of the chambers will sufficiently raise the temperature for
drinking purposes in the coldest weather and obviate standing the jug upon the
hob, thus saving smoking the beer or blacking and spoiling the jug.
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 :-
1st. The improvements relating-to-receptacles such as jugs, pans, or the like
employed for the temporary storage-of-liquids-and-to-the-lids-or-coverings-of-same
substantially as set forth.
2nd. In receptacles such as referred to in the preceding claim the use of an outer
sheil or casing, the intervening space between the shell and vessel serving as a
receptacle-for-a-cooling or warming agent substantially as set forth.
3rd. In receptacles such as those herein before referred to the “employment of an
envelope or surrounding lapping or covering-of-felt-or-other-porous-and-moisture
retaining material substantially as and for the purposes specified.
4th. Providing jugs, pans or like vessels employed for the temporary storage of
liquids with a lid or covering alapted to slide within grooves or guides formed in
the neck of the vessel, or, the grooves may be formed on the edge of the lid
and engage with projections or fillets on the mouth of the jug, the lid being
fitted with a hinged spout or formed with a semi circular outlet substantially as
*set forth.
