I, CARL HAMANN, of Reinbeck, in the Kingdom of Prussia, Manufacturer, do
hereby declare the nature of my invention to be as follows:-
:-
This invention relates to scissors or shears and consists in forming one of the
cutting edges as a separate piece, which is caused to slide in the respective shank of
the scissors in such a manner that it performs when closing, beside the usual more or
less vertical movement of scissors also an independent horizontal cutting movement
along the opposite or fixed cutting edge.
One blade of the improved scissors is as usual of one piece with its shank, while
the other shank has a slot in which is guided an extension of the detached blade,
which can be caused to slide therein by means of a suitable transmitting mechanisın
set in operation by the opening or closing of the scissors. When opening the scissors
the movable blade is shifted outwards and when closing them, the said blade is moved
inwards.
The transmission mechanism may consist of a tooth-wheel rigidly connected with
one shank of the scissors and gearing into teeth on the side of the extension of the
displaceable blade, or a pin at the extension of the blade may catch into an inclined
notch of the other shank of the scissors and thus cause the displacement of the blade
when the scissors are operated or closed, or the same may be operated in any other
convenient manner.

I CARL HAMANN of Reinbeck in the Kingdom of Prussia, Manufacturer do
hereby declare the nature of my 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 relates to scissors or shears and consists in forming one of the cutting
edges as a separate piece which is caused to slide in the respective shank of the
scissors in such a manner that it performs when closing beside the usual more or less
vertical movement of scissors also an independent horizontal cutting movement along
the opposite or fixed cutting edge.
One blade of the improved scissors is as usual of one piece with its shank, while the
other shank has a slot, in which is guided an extention of the detached blade, which
can be caused to slide therein by means of a suitable transmitting mechanism, set in
operation by the opening and closing of the scissors.
When opening the scissors, the movable blade is shifted outwards and when closing
them the said blade is moved inwards.
The transmission mechanism may consist of a tooth wheel rigidly connected with
one shank of the scissors and gearing with teeth on the side of it the extension of
the displaceable blade or a pin on the extension of the blade may catch into an inclined
slot of the other shank of the scissors and thus cause the displacement of the blade,
when the scissors are opened or closed or the same may be operated in any other
convenient manner.
Referring to the annexed drawing showing the invention as applied to garden
shears.
Fig. 1 is a side view.
Fig. 2 is a front view of the shear when closed Fig. 3 is a view of the shank
with movable blade, Fig. 4 shows such shears in open position, Fig. 5 shows the rack
and pinion gear before mentioned. The shears consist of the two shanks A & B
revolvable about pivots o. The blade a is rigidly connected with the shank A in the
usual manner, the blade b belonging to the shank B however (Figs. 3 & 4) carries an
extension displaceably lodged in a slit in the shank B and displaced through suitable
gear or connections with the shank A, outwardly when opening the shears as shown
in Fig. 4 and inwardly when closing the same as shown in Fig. 2. The movement
of the blade b may be effected by a toothed pinion m arranged on the shank A
gearing into a toothed rack p connected with the blade b, Or a pin i with or without
friction roll thereon secured to the extension or haft of the movable blade may be
caused to engage into a slot h in the shank A as shown in the drawing having such
position that the relative moving of the shanks causes a movement of the blade 6 in
the manner required.

page_text: Having now particularly described and ascertained the nature of my Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
In scissors shears and the like :-
1) The combination of a shank having a fixed blade with a shank having a blade
movable therein and adapted to be moved back and forth by suitable mechanism in
the manner and for the purpose set forth.
2) The combination of a shank B having movable blade 6 with pin i and shank A
having blade a and slot h for the purpose set forth.
3) The combination of shank B having movable blade with rack teeth P and
shank having blade a and toothed pinion m for the purpose set forth.
