PROVISIONAL SPECIFICATION.
Improvements in Scissors.
I, EMIL KRUSIUS, of the firm of Gebrüder Krusius, Cutlers, of Solingen,
Germany, do hereby declare the nature of my invention to be as follows:-
My invention relates to that kind of scissors, in which springs are employed, for
pressing the edges of the blades together and thus ensuring an easy and sharp cut.
Instead of applying a spring externally, between the fulcrum and the point of the
blades, I place a spring between the blades at a point beyond the fulcrum, that is
to say between the fulcrum and the handle, so that the spring tends to press the
handles apart, and thereby to keep the points of the blades in contact.
In order to allow the necessary adjustment or play, one of the blades has a
longitudinal slot through which passes the fulcrum pin or rivet.
This arrangement has for its object, that the blades will cut equally well at the
points, as at the top or near the fulcrum, even if the blades are quite straight, and
that the blades are pressed together only at that point of their length, where the
cutting takes place.
The spring is preferably a leaf spring, bent in the centre, so that the two legs or
sides, if continued, would form an obtuse angle; the ends of this spring are in
contact with the inside of one blade, and the bent middle part with the inside of
the other blade.

COMPLETE SPECIFICATION.
Improvements in Scissors.
I, EMIL KRUSIUS, of the firm of Gebrüder Krusius, Cutlers, of Solingen,
Germany, 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 :-
.
My invention relates to that kind of scissors, in which springs are employed, for
pressing the edges of the blades together, in order to ensure an easy and sharp cut.
Instead of applying a spring externally, or between the fulcrum and the point of
the blades, I place it between the blades at a point beyond the fulcrum, that is to
say, between the fulcrum and the handle, so that the spring tends to press the
handles apart, and thereby to keep the points of the blades in contact.
In the accompanying drawing,

invention.

a indicates the spring,
the fulcrum.
In order to allow the necessary adjustment or play, one of the blades has a
longitudinal slot, through which passes the fulcrum pin or rivet.
The described improvement in scissors has for its object, that the blades will cut
equally well at the points, as at the top or near the fulcrum, even if the blades are
quite straight, and if the fulcrum pin has ample clearance. As the blades are
pressed together, or brought into contact, only at that point of their length, where

page_text: the cutting takes place, and as the pressure required is comparatively small, the
scissors will work more easily than usual.
The spring is preferably a leaf spring, bent in the centre, as shown, the ends of
this spring being in contact with the inside of one blade, and the bent middle part
with the inside of the other blade, but I do not confine myself to this particular
shape of spring.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The combination of scissor blades, with a spring a placed between the said blades
and adapted to force the same apart above their fulerum, so that the blades meet
only at the point, where they are intended to cut, substantially as described.
