PROVISIONAL SPECIFICATION left by the said Hector Auguste
Dufrené at the Office of the Commissioners of Patents, with his
Petition, on the 5th March 1868.
I, HECTOR AUGUSTE DUFRENÉ, of No. 10, Rue de la Fidélité, Paris, in
the Empire of France, and 4, South Street, Finsbury, London, Civil
Engineer, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN COVERS OR CAPSULES FOR JARS, POTS, AND OTHER VESSELS," to
be as follows, that is to say:-
This Invention has for object the manufacture of covers or capsules
as a prompt and easy means of closing pots, jars, and other vessels
containing pharmaceutical, edible, and other non-liquid substances.

page_text: I cut a sheet of cardboard or other analogous material into the form
and dimensions of the top of the vessel to be closed; I paste or glue on
to the edges of this piece of cardboard the edge of a ring or band of
india-rubber; I then place over it a sheet of paper or other analogous
material, and interpose or not a band of paper or textile material, the
extremities of which may be pasted or otherwise fixed to the vessel to
be closed. I place the piece of cardboard over the opening and bring
down the india-rubber over the rim of the vessel and thus form the
joint.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Hector Auguste Dufrené in the Great Seal Patent
Office on the 5th September 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HECTOR
AUGUSTE DUFRENÉ, of No. 10, Rue de la Fidélité, Paris, in the Empire
of France, and 4, South Street, Finsbury, London, Civil Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of March, 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 Hector Auguste Dufrené, Her special
licence that I, the said Hector Auguste Dufrené, my executors, adminis-
trators, and assigns, or such others as I, the said Hector Auguste
Dufrené, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 Inven-
tion for "IMPROVEMENTS IN COVERS OR CAPSULES POR JARS, POTS, AND OTHER
VESSELS,' communication from Monsieur Henry Viollet, a person
resident at Tours, in the Empire of France,) upon the condition
(amongst others) that I, the said Hector Auguste Dufrené, 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
"

page_text: 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 Hector Auguste Dufrené, 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, reference being had to the Drawing hereto
annexed, and to the figures and letters marked thereon, that is to
say-
The Invention communicated to me consists in forming a cover for
closing jars, pots, and other vessels containing other than liquid sub-
stances with a piece of cardboard or other analogous material of the
required form surrounded with an india-rubber ring attached to the
edge thereof.
I will now proceed to describe the manner of carrying the Invention
into effect by reference to the accompanying Drawing, in which the
same letters of reference indicate similar parts.
Figure 1 is a plan of the cover; Figure 2, a section of the same on
line A, B, of Figure 1, and Figure 3 is a section shewing the same
applied to a pot.
c is a piece of cardboard which is cut to the form of the opening of
the jar or other vessel to be closed, and surrounded with an india-rubber
ring which is attached to its edges by glue or other suitable adhesive
substance and then takes the shape shewn at b. Over the top of the
cover is pasted a sheet of paper a to strengthen and give it a better
appearance; under the cover may be pasted a sheet of tin foil d. When
the cover is placed on the pot g, Figure 3, the india-rubber ring fits
on to its edges as shewn at b, and thus keeps on the cover and prevents
water from entering the pot. For greater security a strap ƒ may be
attached by glue or paste under the sheet of paper a, and fixed to the
vessel by means of a seal or other suitable means. Figure 3 shews the
ends of the strap held fast by seals f¹.
Having now described the nature of the Invention communicated to
me, and the manner of performing the same, I would have it understood
that I do not confine myself to the precise details herein laid down, but
what I claim is,―

page_text: Firstly. The forming a cover or capsule with a piece of cardboard and
an india-rubber ring, substantially in the manner and for the purposes
herein-before described and represented in the accompanying Drawing.
Secondly. The application of a strap to keep the cover more firmly
fixed as herein-before described and represented in the accompanying
Drawing.
In witness whereof, I, the said Hector Auguste Dufrené, have
hereto set my hand and seal, this Thirty-first day of August,
in the year of our Lord One thousand eight hundred and sixty-
eight.
