PROVISIONAL SPECIFICATION.
An Improvement connected with Scissors and Shears.
I, FRITZ WEINTRAUD, of 2 Cripplegate Buildings, Wood Street, City of
London, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention has for object, constructing one blade of a pair of scissors and
shears with a slot in the shoulder, so that said blade during the cutting has a
forward motion imparted to it, for gathering the material into and between the
blades instead of having a tendency to push the material forward as by the usual
construction.
The ordinary binding pin is employed, and I prefer to fix a flat spring on the
neck of the non-slotted blade with a portion embracing the slotted shoulder of the
other blade to exert pressure and keep the cutting edges in contact.
The forward novement of my slotted shouldered blade is effected by the bite of
the cutting edges as the blades are closing.

An Improvement connected with Soissors and Shears.
I FRITZ WEINTRAUD of 2 Cripplegate Buildings, Wood Street, City of
London, Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention has for object constructing one blade of a pair of scissors and
shears with a slot in the shoulder so that said blade has a motion imparted to it for
gathering the material into and between the blades instead of having a tendency to
push the material forward as by the usual construction.
The ordinary binding pin is employed and I prefer to fix a flat spring on the
neck of the non-slotted blade with a portion embracing the Flotted shoulder of the
other blade to exert pressure and keep the cutting edges in contact.
•
The movement of my slotted shouldered blade is effected by the bite of the
cutting edges and the pressure of the shoulder edges as the blades are closing.
The invention is shown on the annexed drawings.
Figure 1 is an elevation of part of a scissor or shear blade with the alot in the
shoulder.
Figures 2 and 3 show a pair of scissors or shears in a closed and an open state
respectively.

seen at
The point of contact ever variable in the length of the blades becomes a fulcrum,
on which the upper blade moves and any material, which may be between the
blades to be cut, is severed by a guillotine shearing action, the material being, so
to speak, pressed upon and gathered in, and cut simultaneously during the descent
of the upper blade.
The spring is fixed to the neck by a screw pin, and the part which bears
and presses against the shoulder serves, not only to keep the edges of the
blades in cutting condition but covers the slot which prevents entry of dust
and dirt.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
--
1. The construction of scissors and shears with a slot in the shoulder of one
blade, as and for the purpose or purposes described and substantially as shown in
the annexed drawings.
2. Making an elongated hole in the pivotable or connectable part of one blade of
a pair of scissors or shears as set forth with reference to Figure 1 of the annexed
drawings.
