Improved Device for Scissors, Shears, Dressing and other Forceps
and similar Instruments, to keep their Edges in Working Contact.
I, JOHANN MARTIN FRIEDRICH WEIDEMEYER, of No. 10, Markt-Strasse, in the
City of Kiel, in the Kingdom of Prussia and Empire of Germany, Cutler and
Surgical Instrument Maker, do hereby declare the nature of this invention
to be as follows:-
The present invention relates to an improved device for keeping the blades
of scissors, shears, dressing and other forceps and similar instruments, in working
contact.
The device consists of a spring, preferably more or less flat, and long enough
to reach from the pivot of the blades to any convenient point on one of the shanks.
This spring has a hole at one end to enable it to be secured by a screw loosely
to the shank, and at the other end a hook, which just reaches around the pivot
(generally a screw) of the blades.
The spring is slightly bent upwards at the part just in front of the pivot in order
to cause its forward or hooked end to exert a downward pressure upon the top
of the blade when it is hooked around the pivot.
The screw or pivot of the blades is screwed into one of the blades; it possesses
a shoulder upon which the other blade is rotatably mounted and terminates in
a neck and head, around which the hook-like end of the flat spring fits as above
stated and bent in such a manner that the hooked end of it which rests against
the set screw presses one blade upon the other. The spring thus presses only
at one place, which is the one where the cut of the scissors begins; thereby a
sharp clear cut, and at the same time smooth working of the scissors, is attained
The improved fastening device can easily be detached by releasing its hooked
end from the setscrew or pivot. Thereupon the two blades can easily be separated
and the spring fixed into position again.

page_text: do hereby declare the nature of this invention, and in what ma
Ե
be performed, to be particularly described and ascertained in and by the following
statement:
The present invention relates to an improved device for keeping the blades
of scissors, shears, dressing and other forceps and similar instruments, in working
contact.
I attain this object by the means illustrated in the accompanying drawing,
in which:-
Figure 1-is a top view of a pair of scissors provided with my invention;
Figure 2 is a lateral view of Figure 1,
Figures 3 and 4 are detailed views of the spring,
Figures 5 and 6 are similar views to Figures 1 and 2, but showing a modification
of the construction.
Similar letters refer to the same parts throughout the several views.
The device consists of a spring A, preferably more or less flat, and long enough
to reach from the pivot B of the blades to any convenient point on one of the
shanks. This spring has a hole c at one end to enable it to be secured by a stud
or screws loosely to the shank, and at the other end a hook or slot, which just
reaches around the pivot (generally a screw) B of the blades.
The spring is slightly bent upwards at the part just in front of the pivot in
order to cause its forward or hooked end to exert a downward pressure upon the
top of the blade when it is hooked around the pivot.
The screw or pivot B of the blades is screwed into one of the blades; it
possesses a shoulder e upon which the other blade is rotatably mounted and
terminates in a neck f with a head f', around which neck the hook-like end of
the flat-spring fits as above stated; the spring is bent in such a manner that
the hooked end of it which embraces the neck of the pivot B presses one blade
upon the other. The spring thus presses only at one place, which is the one
where the cut of the scissors begins; thereby a sharp clear cut, and at the same
time smooth working of the scissors is attained. The improved fastening device
can easily be detached by releasing its hooked end from the pivot B. Thereupon
the two blades can easily be separated and the spring fixed into position
again.
In the modification shown by Figures 5 and 6 the pivot B is not screwed into
one of the blades but is loosely inserted in a suitably shaped hole of the respective
blade and prevented from slipping through this hole by a yielding abutment f
(spring, resilient arms or the like) attached to the pivot-pin and resting against
or upon the outer side of the corresponding blade. The spring A is not screwed
to the shank of the blade but engages with its hole c a suitable stud or projec-
tions of the said shank, so that when the spring A is released from the stud s'
the slotted end of the spring engaging the neck of the pivot may be drawn off
from the latter and the scissors thus taken easily into its constituent parts.
Owing to the property of taking into parts instruments of the said kind when
provided with my invention, such instruments are particularly applicable for
surgical use as the single parts may be thoroughly aseptically treated.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
(1) Improved device for scissors, shears, dressing and other forceps or similar
instruments to keep their cutting edges in working contact, comprising, in com-
bination with the blades of such instruments, a pivot (B) engaging one blade
and having a shoulder (e) upon which the other blade turns, said pivot also having
a reduced neck (f) and a head (f), and a flat spring (A) one end of which engages
the neck of the pivot whilst the other end is secured to the shank of the adjacent
blade, substantially as and for the purpose set forth.

page_text: (2) The improved device for keeping the cutting edges of scissors, shears and
the like in working contact constructed, arranged and operating substantially as
herein before described with reference to and shown in the annexed drawing.
Dated the 16th day of August 1898.
