Year: 1863

page_text: LETTERS PATENT to Frederick Charles Phillip Hoffmann, of Newgate
Street, in the City of London, Engineer, for the Invention of "IMPROVE-
MENTS IN SHEARS FOR CUTTING METAL AND OTHER SUBSTANCES."
Sealed the 26th February 1864, and dated the 29th August 1863.
PROVISIONAL SPECIFICATION left by the said Frederick Charles Phillip
Hoffmann at the Office of the Commissioners of Patents, with his
Petition, on the 29th August 1863.
I, FREDERICK CHARLES PHILLIP HOFFMANN, of Newgate Street, in the City
of London, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN SHEARS FOR CUTTING METAL AND OTHER SUBSTANCES," to be
as follows:-
!!My Invention consists in fitting the levers by which the movable blade is
worked above the fixed blade or cutting plate, and in fixing the axis on which
the back of the movable blade is free to move also above the level of the fixed
plate. I undercut the lower part of the bracket in such manner as to allow
the portions severed, say, from a plate, as well as the plate itself to pass freely
away, one on one side and the other on the opposite side of the bracket.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Charles Phillip Hoffmann in the Great Seal Patent

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of August, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Frederick Charles Phillip Hoffmann, Her special licence
that I, the said Frederick Charles Phillip Hoffinann, my executors, adminis-
trators, and assigns, or such others as 1, the said Frederick Charles Phillip
Hoffmann, 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
SHEARS FOR.
CUTTING METAL AND OTHER SUBSTANCES," upon the condition
(amongst others) that I, the sail Frederick Charles Phillip Hoffmann, my
executors or administrators, by an instrument in writing under my, or their,
or one of their bands and seals, should particularly describe and ascertain the
nature of the said Invention, aud 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 Frederick Charles Phillip Hoffmann,
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 thereof, reference being had to the Drawings
hereunto annexed, that is to say :-
· My Invention consists in fitting the levers by which the movable blade is
worked above the fixed blade or cutting plate, and in fixing the axis on which
the back of the movable blade is free to move also above the level of the fixed
plate. I undercut the lower part of the bracket in such manner as to allow
the portions severed, say, from a plate, as well as the plate itself to pass freely
away, one on one side and the other on the opposite side of the bracket.
Figures 1 and 1 of the accompanying Drawings are views of the two sides;
Figure 2 a back view, and Figure 3 a front view of shears constructed
according to my Invention.
a is the movable blade, and b the fixed blade or cutting plate; c is the lever
by which the movable blade is worked; it is fitted above the fixed blade, and
works from an axis at d; e is the axis on which the back of the blade a is
free to move; this axis is also fixed above the level of the blade b. The
lever c is connected by a link to the fore end of the frame 9 which carries

page_text: the blade a. The bracket h is undercut at i, to allow the portions severed,
say, from a plate, as well as the plate itself to pass freely away, one on one
side and the other on the opposite side of the bracket. Figure 4 is a side
view, Figure 5 a back view, and Figure 6 a front view of shears in which the
axis d of the lever c is fitted near the back of the shears, and is connected by
a link to the back end of the frame g in which the movable blade is
fixed. The same letters refer to corresponding parts to those in Figures
1, 2, and 3.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim constructing
shears for cutting metal and other substances with the axis of the movable
blade above the level of the fixed plate, and with the bracket undercut, as
herein-before described and illustrated in the accompanying Drawings.
In witness whereof, I, the said Frederick Charles Phillip Hoffmann, have
hereunto set my hand and seal, this Twenty-ninth day of February,
One thousand eight hundred and sixty-four.
F. C. P. HOFFMANN. (L.S.)
