Merchants, both of No. 82, Boulevard Sébastopol, Paris, France,
for the Invention of "IMPROVEMENTS IN APPARATUS FOR OPENING PRE-
PROVISIONAL SPECIFICATION left by the said Edme Achille Paillard
and Zacharie Gourlan at the Office of the Commissioners of Patents,
with their Petition, on the 20th May 1873.
We, EDME ACHILLE PAILLARD and ZACHARIE GOURLAN, Merchants,
both of No. 82, Boulevard Sébastopol, Paris, France, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR
OPENING PRESERVED MEAT, FISH, POTTED MEAT, AND OTHER TINS," to be as
follows:-
The object of this Invention is to facilitate opening preserved meat
and other tins expeditiously and without danger.

page_text: blade; this carriage is adjustable at the desired height, in accordance
with that of the tin to be operated on, and is fixed by an adjusting
screw. The blade slides with the carriage up and down the slot or
aperture in the frame, and is actuated by a movable lever to which
it is attached by a pin; one end of the lever is articulated to the
carriage, and the other terminates in a handle. On acting by a down-
ward pressure on the lever the blade penetrates the tin. The blade is
directed in its movements by two guides, and the course of the lever is
determined by a detent.
Instead of the lever acting by a downward pressure it may be arranged
to act by an upward motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edme Achille Paillard and Zacharie Gourlan in
the Great Seal Patent Office on the 12th November 1873.
* TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDME
ACHILLE PAILLARD and ZACHARIE GOURLAN, Merchants, both of No. 82,
Boulevard Sébastopol, Paris, France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of May, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Edme Achille Paillard and
Zacharie Gourlan, Her special licence that we, the said Edme Achille
Paillard and Zacharie Gourlan, our executors, administrators, and assigns,
or such others as we, the said Edme Achille Paillard and Zacharie
Gourlan, our 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 APPARATUS FOR OPENING PRESERVED MEAT, FISH, POTTED
MEAT, AND OTHER TINS," upon the condition (amongst others) that we,
the said Edme Achille Paillard and Zacharie Gourlan, our exccutors or
administrators, by an instrument in writing under our, or their, or one

page_text: 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
5 of the said Letters Patent.
NOW KNOW YE, that we, the said Edme Achille Paillard and
Zacharie Gourlan, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and accom-
O panying Drawings, that is to say :—
The object of this Invention is to facilitate opening preserved meat
and other tins expeditiously and without danger.
The apparatus consists of a vertical slotted frame fixed to a bottom
plate on this frame slides a movable carriage bearing the cutting
blade; this carriage is adjustable at the desired height, in accordance
with that of the tin to be operated on, and is fixed by an adjusting
screw. The blade slides with the carriage up and down the slot or
vertical aperture in the frame, and is actuated by a movable lever
to which it is attached by a pin; one end of the lever is articulated
to the carriage, and the other terminates in a handle. On acting by a
downward pressure on the lever the blade penetrates the tin. The blade
is directed in its movements by two guides, and the course of the lever
is determined by a detent.
Instead of the lever acting by a downward pressure it may be arranged
to act by an upward motion.
Fig. 1 is a front view, and Fig. 2 a side view of the apparatus. A
is the vertical slotted frame attached to the bottom plate P, which may
be screwed or fixed to a bench; H is the movable carriage sliding on
the frame, and adjustable by the screw D; f is the cutting blade con-
nected to the lever E by the pin K, the other end of the lever is
attached to the carriage H by the screw v. The blade is maintained
within two guides c, c, which give it free play; L is the detent limiting
the course of the lever E.
Fig. 3 is a modification of the same principle; in this the lever is
raised to bring the blade into operation; Fig. 4 is a plan of the same;

page_text: the same letters of reference indicate like parts in Figures 1 to 4
inclusive.
Fig. 5 is a side view, and Fig. 6 a plan of a similar apparatus to
the preceding one; here, the frame P has an internal groove serving
to guide the blade f; M is the vertical support to the lever E; in this 5
instance the guide to the blade is the screw K; a fly wheel V is
attached to one end of this screw for regulating the blade at the required
distance.
We claim as our Invention,―
1st. The combination with a vertical slotted frame A of a vertically 1
adjustable carriage H, in combination with a cutting blade fand lever E,
as and for the purposes substantially as described.
2nd. The internally grooved frame P, in conjunction with the vertical
support M, screw K, and fly wheel V, in the manner and for the
purposes herein mentioned, and as illustrated by the accompanying 1
Drawings.
In witness whereof, we, the said Edme Achille Paillard and
Zacharie Gourlan, have hereunto set our hands and seals, this
Eighth day of November, in the year of our Lord One thousand
eight hundred and seventy-three.
