It consists, in a box of any convenient form or material, in which is placed a
moveable diaphragm of a diameter equal to that of the box, and on which is
placed the matter or substance to be preserved enclosed in a suitable envelope
assuming the form of the box; this box is furnished with a hermetically
closing lid. An endless screw, the lower extremity of which is connected
with the metal plate bottom of the box in which it turns, traverses the
diaphragm, the pasty substance, the box in its whole height and its lid, above
which it ends in a handle which serves to actuate it. By imparting a
rotation movement to this screw by means of the handle when the pasty
substance is placed inside the box, the diaphragm threaded with a worm like
that of the endless screw is compelled to rise inside the box towards or against
the pasty substance or matter, which being pressed by the diaphragm against
the lid issues in such a quantity as may be required by an opening managed
in the lid and which is afterwards closed when it is no longer needed to
extract any more of the said substance.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henri Adrien Bonneville in the Great Seal Patent Office on
the 23rd April 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Oflice, 24, Rue du
Mont Thabor, Paris, in the Empire of France, and 38, Porchester Terrace,
Bayswater, in the County of Middlesex, Patent Agent, send greeting.
* WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of November, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henri Adrien Bonneville, Her special license that I, the said Henri
Adrien Bonneville, my executors, administrators, and assigns, or such others
as I, the said Henri Adrien Bonneville, my executors, administrators, and
assigns should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein 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
"IMPROVEMENTS IN THE METHOD OR MEANS FOR PRESERVING PASTY MATTERS AND
SUBSTANCES AND APPARATUS THEREFOR," a communication from Edouard Charton,

page_text: a person resident at Rue Lepic, in Paris aforesaid, Painter, upon the
condition (amongst others) that I, the said Henri Adrien Bonneville, my
executors or administrators, by an instrument in writing under my, or their,
or one of 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 Henri Adrien Bonneville, 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:--
The Invention communicated to me relates to the preserving of pasty
matters and substances so as to prevent them becoming dry and corrupt,
whilst allowing of taking out a greater or lesser quantity as may be needed.
It consists in a box of any convenient form or material in which is placed a
moveable diaphragm of a diameter equal to that of the box, and on which is
placed the matter or substance to be preserved enclosed in a suitable envelope
assuming the form of the box. This box is furnished with a hermetically
closing lid. An endless screw, the lower extremity of which is connected
with the metal plate bottom of the box in which it turns, traverses the
diaphragm, the pasty substance, the box in its whole height, and its lid,
above which it ends in a handle which serves to actuate it. By imparting a
rotation movement to this screw by means of the handle when the pasty
substance is placed inside the box the diaphragm, threaded with a worm like
that of the endless screw, is compelled to rise inside the box towards or
against the lid, the pasty substance or matter being pressed by the diaphragm
against the lid issues in such a quantity as may be required by an opening
managed in the lid, and which is afterwards closed when it is no longer needed
to withdraw any more of the said substance.
Having thus summarily stated the said Invention, I will now proceed more
particularly to describe the same, reference being had to the accompanying
Drawings, Fig. 1 of which is an outside vertical view of the box; Fig. 2 a
vertical section of the same; Fig. 3 a view of the handle by itself, and
Figs. 4 and 5 are a plan and a section representing a modification in the lid
of the box. Like letters of reference indicate in Figs. 1 and 2 corresponding
parts.
A is the lid perforated with a hole A, through which issues the pasty
substance; B, an inside tube in which is placed the pasty substance; C is

page_text: the moveable diaphragm, made of metal, india-rubber, leather, or other
suitable material; D is a nut on the upper extremity of the diaphragm's
driving screw; E, the box of a circular form made of metal, pipe-clay, or
other suitable material; F is a sheet of metal or of parchment lining the inside
tube B to prevent the loss of any of the pasty substance when pressed; G is
the endless screw held at its lower end by a peg, and at its upper end by the
nut D; H, the handle or key fixing itself upon the nut D in order to turn
the screw G; I is a cavity or recess into which the metallic or parchment
lining is folded down when the diaphragm rises; J is a cloth preserving the
sheet of metal or parchment when it rises.
From the foregoing description the working of the apparatus will be readily
understood without entering upon more ample explanations.
For substances the consistency of which is too great, and whose easy out-
flow through the hole in the lid would consequently be impeded, this lid may
.be disposed as represented in the Figs. 4 and 5, that is to say, it may be
composed of a circular band or crown a, adapting itself on the top of the box
and divided at its centre by a transversal bar b, having on each side a slot c,
in which are placed little planks of the shape of a half moon, retained on their
outer edges by any convenient means, and which are withdrawn in order to
remove the pasty substance by means of the band and which are afterwards
replaced.
Having thus described the nature of the said Invention and the manner of
carrying the same into effect, what I claim and desire to secure by the said
Letters Patent is, the combination with a moveable diaphragm at top and
bottom actuated by an endless screw or other suitable means, of a box or
recipient intended to preserve pasty substances, substantially as herein-before
fully set forth and described and represented in the accompanying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have here-
unto set my hand and seal, this Twentieth day of April, in the
year of our Lord One thousand eight hundred and sixty-eight.
H. BONNEVILLE. (L.S.)
