PROVISIONAL SPECIFICATION.
Improvements in Scissors and Forceps for Surgical and other
purposes.
JOHN BLYDE, Cutlery Manufacturer, of Clintock Works, Sheffield, in the County
of York, do hereby declare the nature of this invention to be as follows:
: -
My invention consists in improvements in scissors, forceps, and such instru-
ments as may be of a like nature. It is well known that for surgical purposes
the scissors and forceps used must be perfectly cleaned after each operation, and
in order to do this it is necessary to take them in pieces so that all the parts can
be chemically cleaned. In the ordinary type of scissors the blades are held
together by a screw which to take the blades apart would require unscrewing.
In my scissors this screw or rivet is fastened permanently only in one of the
blades.
Having a hole in the other blade in which the screw works freely.
Thus the blade can be lifted out easily. In order to hold the bladis together
a clamp is fixed by screwing or otherwise fastening to the other blade.
This clamp is permanently attached to a projecting lug at the side of the blade
which keeps the edges on the cut.
Another feature of my invention is that clamp is put at the blade side of screw,
and not at the shank side.
Thus the clamp causes the blades to be more firmly held to the cut than in
existing scissors and forceps.
Improvements in Scissors and Forceps for Surgical and other
purposes.
I, JOHN BLYDE, Cutlery Manufacturer, Clintock Works, Sheffield, in the County
of York, 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 improvements in the construction of scissors, forceps
and other like jointed instruments, and more particularly to the fulcrum joint
of same.
The annexed drawings illustrate how my invention is carried into practice.
Fig. 1, represents a pair of scissors made according to my invention.
Fig. 2. represents the hooked clamp.

page_text: Figs. 3 and 4, show the two blades separated.
The object of my invention is to enable the two parts of the scissor or like
instrument to be readily separated and put together again, and to hold them
firmly upon the cut when in position.
It is absolutely necessary that scissors and forceps used for surgical purposes
must be perfectly cleaned after each operation, and in order to accomplish this
it is necessary to take them to pieces so that the joints and every part can be
subjected to chemical cleaning, or other cleaning process.
In scissors of the ordinary type, the blades are held together by means of a
screw, and in order to separate them it would be necessary to remove the said
screw, a troublesome process and which would soon cause the blades to work
loosely.
In carrying out my invention I secure the fulcrum pin P, permanently to one
of the blades A, and make a corresponding hole H, in the blade B, to receive it,
and in which it can turn freely.
To secure the blades together and to keep them properly on the cut, I form
upon the back edge of the blade B, a projection or lug L, and upon this projecting
lug I permanently secure a hook shaped clamp or finger C, seen in Fig. 2, which
extends across the inner face of the blade, with a space between to receive the
blade A.
This clamp or finger C, is situated upon the blade side of the pin P, rendering
it more efficacious in holding the two blades firmly to the cut than hitherto.
To put the blades together, the blade A, is placed across the blade B, and the
pin P, inserted into the hole H, the blade A, is then turned under the clamp C;
to separate them the movement described is reversed.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed I declare that what I claim
is:
1 The improvements in detachable blades of scissors, forceps and like instru-
ments as herein before described, with reference to the drawings.
2-In scissors, forceps and like instruments, in which the blades are detachable,
the use of a hooked clamp C, secured upon a lug L, projecting from the back
edge of one of the blades at a suitable distance in front of the fulcrum pin, and
bearing upon, the other blade, as herein before described and shown in the draw-
ings annexed.
3-In scissors, forceps, and like instruments in which the two parts are detach-
able, a hooked clamp C, formed upon the back of one of the blades from the same
continuous material in front of the fulcrum, to hold the other blade in position,
as herein before described.
