AN IMPROVED UNSPILLABLE PAIL OR VASE
Year: 1868

page_text: LETTERS PATENT to Frederic Barnett, of No. 164, Rue de Rivoli,
in the City of Paris, in the Empire of France, Merchant, for the
Invention of "AN IMPROVED UNSPILLABLE PAIL OR VASE."
Sealed the 28th October 1868, and dated the 2nd May 1868.

page_text: to render all vessels manufactured after my system, whether for
agricultural, domestic, or other purposes, proof against the accidents
above recited by the following means.
Figure I. represents the outward form on the principle of which I shall
make the said pails or vases.
Firstly. Larger at the base than at the summit, by which means they
will be less liable to upset, but in the event of such accident occurring
this form will greatly favor the action of the self-acting valve G.
Secondly. The base of the pail or vase I, I, being larger than its
summit, this form will when the vessel is on its side dispose the liquid
contents to flow to the only opening at F, and such flow or pressure of
the liquid will naturally propel or press the cone G into or against the
truncated cone F. If the pail or vase should be entirely upset it is
evident that the cone G will close the orifice in the truncated cone F, by
which in its normal position the liquids flow into the vase.
In fashioning the said vessels I make the covering B, C, C, B,
concavely conical to guide the liquids to the central and only
opening C, C, whence they descend, passing between the cones F and G,
composing together the self-acting valve.
A, B, A, B, are circles made of metal, wood, ceramic, or other
materials employed in the construction of the said vessels surrounding
the cover B, C, C, B. In constructing these pails or vases all the parts
must be thoroughly soldered, joined, or hermetically closed, so that no
communication with the interior can exist except by the orifice at C, C.
I render these pails or vases unspillable by the disposition of the self-
acting valve G, which I fix beneath the orifice C, C. When these pails
or vases are in their normal position all liquids will flow into the interior
by the orifice C, C, until upset or thrown on their sides B, I, B, I, and
it becomes evident that in such cases the liquids contained in them will
while striving to escape by their impulsion close the moveable cone G
into the fixed truncated cone F, and by such action effectually close the
the truncated cone F, by which otherwise the liquids would escape, that
is to say, when the vase is thrown on its side or upset the action
of the cone G, guided by its rod K, shuts water-tight into the

page_text: cone F, and thereby as effectually prevents the escape of its contents as
though the orifice in the cone F were corked. By such construction
the vase in its normal position permits of its filling, and if upset closes:
instantly by its own action.
I reserve the right of making the pails or vases in whatever forms and
of whatever dimensions I may find desirable, and I say the same of the
self-acting valve as regards the material and manner of construction
which it may suit me to employ to obtain the best practical. result from
my Invention, but I prefer them as above described and drawn.
For the purpose of cleansing, examination, or repairs I make that
portion of the cover included between D, C, C, D, to unscrew at D, D,
and by such means leave an aperture of several inches in diameter by
which the hand can be introduced; I also provide the spout J whereby'
to empty the vase, the same being otherwise kept closed by a screw or
simple cork. I shall employ a slightly concave plate L fixed at the
extremity of bar K. to assist in closing promptly the cone G.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederic Barnett in the Great Seal Patent Office.
on the 28th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,' FREDERIC
BARNETT, of No. 164, Rue de Rivoli, in the City of Paris, in the Empire
of France, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her.
Letters Patent, bearing date the Second day of May, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty--
first year
of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Frederic Barnett, Her special licence.
that I, the said Frederic Barnett, my executors, administrators, and;
assigns, or such others as I, the said Frederic Barnett, my executors,.
administrators, and assigns, should at any time agree with, and no

page_text: others, from time to time and at all times thereafter during the
term thercin expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
UNSPILLABLE PAIL OR VASE," upon the condition (amongst others)
that I, the said Frederic Barnett, my executors or administrators,
by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Frederic Barnett, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement :-
That all the pails or vases, portable or otherwise, in use to the present
day, whether for agricultural, domestic, manufacturing, or other purposes,
labour under the serious disadvantage of being easily upset and
spillable, thereby entailing by a blow or shock the upsetting and
spilling of a portion and sometimes the whole of their contents. By
means of a new and improved construction I propose to remedy
this inconvenience, and to render all vessels manufactured after any
system, whether for agricultural, domestic, or other purposes, proof
against the accidents above recited by the following means.
Figure 1 represents the outward form on the principle of which I shall
make the said pails or vases.
Firstly. Larger at the base than at the summit, by which means
they will be less liable to upset, but in the event of such accident
occurring this form will greatly favor the action of the self-acting
valve G.
Secondly. The base of the pail or vase I, I, being larger than its sum-
mit, this form will when the vessel is on its side dispose the liquid con-
tents to flow to the only opening at F, and such flow or pressure of
the liquid will naturally propel or press the cone G into or against the
truncated cone F. If the pail or vase should be entirely. upset it is
evident that the cone G will close the orifice in the truncated cone F,
by which in its normal position the liquids flow into the vase.

page_text: In fashioning the said vessels I make the covering B, C, C, B, con-
cavely conical to guide the liquids to the central and only opening C, C,
whence they descend, passing between the cones F and G, composing
together the self-acting valve.
A, B, A, B, are circles made of metal, wood, ceramic, or other
materials employed in the construction of the said vessels sur-
rounding the cover B, C, C, B.
In constructing these pails or
vases all the parts must be thoroughly soldered, joined, or her-
metically closed, so that no communication with the interior can
exist except by the orifice at O, C. I render these pails or vases
unspillable by the disposition of the self-acting valve G, which I fix
beneath the orifice C, C. When these pails or vases are in their
normal position all liquids will flow into the interior by the orifice C, C,
until upset or thrown on their sides B, I, B, I, and it becomes evident
that in such cases the liquids contained in them will while striving
to escape by their impulsion close the moveable cone G into the fixed
truncated cone F, and by such action effectually close the truncated
cone F, by which otherwise the liquids would escape, that is to say,
when the vase is thrown on its side or upset, the action of the cone G,
guided by its rod K, shuts water-tight into the cone F, and thereby as
effectually prevents the escape of its contents as though the orifice in
the cone F were corked. By such construction the pail or vase in
its normal position permits of its filling, and if upset closes instantly
by its own action.
For the purpose of cleansing, examination, or repairs I make
that portion of the cover included between D, C, C, D, to unscrew
at D, D, and by such means leave an aperture of several inches
in diameter by which the hand can be introduced; I also provide
the spout J whereby to empty the pail or vase, the same being
otherwise kept closed by a screw or simple cork.
I shall employ
a slightly concave plate L, fixed at the extremity of the bar K, to
assist in closing promptly the cone G.
Figure I. represents the form of the pail or vase I prefer; Figure II.
is a vertical section or coupe of same.
I reserve the right of making the pails or vases in whatever forms
and of whatever dimensions I may find desirable, and I say the same
of the self-acting valve as regards the material and manner of con-

page_text: struction which it may suit me to employ to obtain the best practical
result from my Invention, but I prefer them as above described and
drawn.
In witness whereof, I, the said Frederic Barnett, have here-
unto set my hand and scal, this Twenty-fourth day of October,
1868.
