Office of the Commissioners of Patents, with his Petition, on the
20th May 1868.
I, ROBERT FROEHLICH, of South Grove East, Mildmay Park, in the
County of Middlesex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MEANS OR APPARATUS FOR OPENING SARDINE AND OTHER.
SHEET METAL CASES OR RECEPTACLES, WHICH IMPROVEMENTS ARE ALSO APPLICABLE

from abroad by Bellina Froehlich, of West Twelfth Street, New York,
in the United States of America, to be as follows:-

page_text: The Invention has for its object improvements in means or apparatus
for opening sardine and other sheet metal cases or receptacles, which
improvements are also applicable to cutting sheet metals and other
materials.
For this purpose an instrument is employed one jaw of which is
pointed and formed with a suitable cutting edge, and somewhat in
the form of one jaw of a pair of shears, whilst the other jaw is provided
with a pair of rollers or discs mounted on a suitable axis, and between
which rollers the first-named jaw is caused to work.
When about to open a sardine or other case the pointed jaw is forced 1
through the case, and the two jaws are operated in a similar manner
to operating a pair of shears, the rollers at such time being supported
upon the case, and thereby regulating the depth to which the pointed
jaw is allowed to enter the case or other receptacle. A suitable spring
is employed to force the jaws open, as is well understood.
If desired, only one roller or disc may be employed in combination
with the pointed jaw.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Froehlich in the Great Seal Patent Office
on the 20th November 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
FROEHLICH, of South Grove East, Mildmay Park, in the County of
Middlesex, 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 sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Robert Froehlich, Her special
licence that I, the said Robert Froehlich, my executors, adminis-
trators, and assigns, or such others as I, the said Robert Froehlich,
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,
usc, cxcrcise, and vend, within the..United Kingdom of Great Britain.

"IMPROVEMENTS IN MEANS OR APPARATUS FOR OPENING SARDINE AND OTHER
SHEET METAL CASES OR RECEPTACLES, WHICH IMPROVEMENTS ARE ALSO APPLICABLE
TO CUTTING SHEET METALS AND OTHER MATERIALS," a communication to me-
from abroad by Bellina Frochlich, of West Twelfth Street, New York, in,
the United States of America, upon the condition (amongst others) that.
I, the said Robert Frochlich, 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 Inven--
tion, 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 Robert Froehlich, do hereby
declare the nature of my said Invention, and in what manner the same
3 is to be performed, to be particularly described and ascertained in
and by the following statement thereof, that is to say :—
The Invention has for its object improvements in means or apparatus
for opening sardine and other sheet metal cases or receptacles, which
improvements are also applicable to cutting sheet metals and other
) materials.
For this purpose an instrument is employed one jaw of which is
pointed and formed with a suitable cutting edge, and somewhat in
the form of one jaw of a pair of shears, whilst the other jaw is provided
with a pair of rollers or discs mounted on a suitable axis, and between
which rollers the other jaw is caused to work.
: When about to open a sardine or other case the pointed jaw is forced
through the case, and the two jaws are operated in a similar manner to
operating a pair of shears, the rollers at such time being supported upon
the case, and thereby regulating the depth to which the pointed jaw is
allowed to enter the case or other receptacle. A suitable spring is
employed to force the jaws open, as is well understood.
If desired, only one roller or disc may be employed in combination
with the pointed jaw.
And in order that the Invention may be more fully understood and
5 readily carried into effect I will proceed, aided by the accompanying
Drawings, more fully to describe the same.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view, Figure 2 is a plan, and Figure 3 is an end
view of cutting apparatus constructed according to the Invention.
a is one jaw of the cutter, having a suitable cutting edge formed thereon,
and being pointed at its end. The other jaw b is provided with a pair of
rollers 6', between which the jaw a is caused to work. The two jaws are
pin-jointed together at c, and are provided with handles a¹ and b³, by
which the jaws a, b, are forced together in the act of cutting, whilst a
spring d acts to open the jaws when pressure is removed from the
handles.
When it is desired to open a sardine or other box or case the pointed
end of the jaw a is first forced through the metal, and the handles are
grasped and operated in a similar manner to those of a pair of shears, the
rollers b' at such time being supported upon the box or case, and thereby
regulating the depth to which the jaw a is allowed to enter the box or.
other receptacle.
If desired, only one roller or disc 6' may be employed in combination
with the jaw a, and the cutting edge of the jaw a may when the appa-
ratus is required for cutting sheet metal and other materials be made of a
shape suitable to the work it is intended to perform.
Having thus described the nature of the said Invention, and the mode
in which the same may be carried into effect, I would have it understood
that I do not confine myself to the precise details herein shewn and
described so long as the peculiar character of the Invention be retained,
substantially as herein shewn and described.
In witness whereof, I, the said Robert Froehlich, have hereunto set
my hand and seal, this Eighteenth day of November, in the
year of our Lord One thousand eight hundred and sixty-eight.
