Year: 1872

page_text: LETTERS PATENT to Charles Lund, of Fleet Street, in the City of
London, Manufacturer, for the Invention of "AN IMPROVED CUTTING
INSTRUMENT FOR OPENING METAL BOXES OR CASES."
Sealed the 31st December 1872, and dated the 9th November 1872.
PROVISIONAL SPECIFICATION left by the said Charles Lund at the
Office of the Commissioners of Patents, with his Petition, on the
9th November 1872.
I, CHARLES LUND, of Fleet Street, in the City of London, Manu-
facturer, do hereby declare the nature of the said Invention for "AN
IMPROVED CUTTING INSTRUMENT FOR OPENING METAL BOXES OR CASES," to be as
follows:-
My improved cutting instrument for opening metal boxes or cases is
composed of a pair of arms or levers connected together by means of a
pin joint at a short distance from their front ends while their opposite
ends are so shaped as to be conveniently grasped by the hand.
The front end of the lower arm has a slot cut vertically through it for

page_text: arm forms the cutting blade, the cutting edge being on the upper side
of the same; and the under side of the slotted portion of the lower
arm forms the bearing against which the blade cuts. The under side of
the lower arm and the under side of the blade are both curved or
rounded so as to be moved or slid easily along the metal case as the
cutting operation proceeds. A. bent spring, rivetted at one end to the
handle of the upper arm and resting at its other end upon the lower
arm tends to force, the arms apart and therefore to keep the cutting
blade below the slotted part of the upper arm.
The action is as follows:-A hole having been made in the metal case
to be opened the blade is inserted therein, the handle ends of the two
arms are then pressed together so as to force up the blade into the slot
of the lower arm, and in thus rising the blade will cut so much of the
metal as is between the front portions of the two arms. The pressure on
the arms being then removed the spring forces them again apart and the
blade descends ready for the next cut, the instrument being meanwhile
slid the requisite distance along the top of the case, and so on, the action
resembling that of sheep shears.
An abutment on one of the arms prevents them being brought too
closely together. When the instrument is not in use it may be kept
closed by a loop or stirrup on one arm being slipped over the end of the
other arm.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Lund in the Great Seal Patent Office
on the 22nd January 1873.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
LUND, of Fleet Street, in the City of London, Manufacturer, send

that I, the said Charles Lund, my executors, administrators, and

to be opened the blade e is inserted therein, the handle ends of the two
arms are then pressed together into the position Figure 1 so as to force
up the blade into the slot of the lower arm, and in thus rising the
blade will cut so much of the metal as is between the front portions of
the two arms. The pressure on the arms being then removed the
spring forces them again apart, and the blade descends ready for the
next cut, the instrument being meanwhile slid the requisite distance
along the top of the case, and so on, the action resembling that of sheep
shears.
An abutment on the arm prevents the two arms being brought
too closely together. When the instrument is not in use it may be kept
closed by a loop or stirrup ½ on one arm being slipped over the end of
the other arm.
In witness whereof, I, the said Charles Lund, have hereunto set
my hand and seal, this Eleventh day of January, One thousand
eight hundred and seventy-three.
