Improvements in Scissors.
We, JOHANN BECKMANN and WILHELM ROHR, both residents of Solingen, in
the Province of the Rhine, Kingdom of Prussia, German Empire, Manufacturers, 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:-
Our invention relates to improvements in scissors and has for its object to
increase the usefulness and adaptability of scissors by forming the blades and
handles alike, that is to say, in such a way, that the blades, which are provided
with two sharp edges, may be used as handles, and reversely, so as to enable a
person to use either one or the other pair of cutting-blades.
The grips by
means of which the scissors are held and worked, are in this case detachable and
may be fastened to the blades at either end, so that one or the other half of
the scissors may be used as handles whilst the respective opposite half acts as
blades during that time.
In order that our invention may be fully understood, we will proceed to describe
the same by the aid of the accompanying drawings, in which:
Fig. 1 is a front view of our improved scissors, drawn to natural size.
Fig. 2 is a side view of the same.
Fig. 3 is a front view of a pair of scissors of smaller size than those shown in
Fig. 1.
Fig. 4 shows details of the grip and means for securing the same to the blades.
Fig. 5 shows a modification.
Similar letters refer to similar parts throughout the several views.
In carrying our invention into effect, we provide two double-blades a g and b h,
which are connected by a pin or screw t in the usual way in or near their central
point, so that the halves ab of the double-blades are on one side and the
halves g h on the other side of said screw or pin. Each of the blades is pro-
vided with cutting-edges on both sides and has near its two pointed (or dumb) ends
transverse grooves n with holes o for fastening the grips by aid of screws s passing
through holes of lugs p.
Instead of the screws and the lug p grasping the blade on both sides, we may
employ the modified means illustrated by Fig. 5. The grip † is provided with a
lug y having a recess for the reception of the spring z. The lug y and spring z are
entered into a hole j formed between the blade and a small cover / secured to the
The spring z is bent down while passing through the hole j, and hereafter
the end of the spring, which is formed with an offset serving as a stop, is raised so
as to lock the grip rin relation to the blade.
same.
The advantages of our improved scissors are the following:
First; a pair of scissors of the new kind replaces two pairs of the old kind;
secondly, the blades, having eight cutting edges instead of two as usual, may be
employed four times as long without requiring to be sharpened; and thirdly, all
parts may be cleaned easily, as the blades are entirely free to rotate around the
central pivot.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:―
1. A pair of scissors consisting of two double-biting blades pivoted to one another
so as to be entirely free to rotate around the pivot, and of detachable grips adapted
to be fastened to any of the four ends of the blades, for the purpose as described,

ally connected double-biting blades a g and b, having transverse grooves n and
holes 0, of the detachable grips r, having lugs p, and the screws s, substantially and
for the purpose as described.
