of a mechanically or partly mechanically constructed or fitted joint, commonly
called a "he and she joint," in combination with other means such as those before
described, if desired but not of necessity, and so that the several parts may be made
in quantities and be interchangeable.
A further improvement which I introduce in scissors and shears is in adapting
them to be used as a knife or the like, separately from their shearing action I make
one or both of the blades with two cutting edges instead of one as heretofore, that
is, in addition to the usual inside shearing edge, I make an outside cutting edge at G,
either plain like a knife, or toothed like a saw, or a combination of both, or of a
knife and a file; but I especially exclude any claim to the file-cut edges of nail
scissors.
Instead of making the before described edge at G, I may construct the scissors
or shears so that when the blades are closed, the cutting edge of one blade will
project past the back of the other blade in such a manner that it can be used for
cutting purposes without necessitating the opening of the scissor or shear.
The improvements hereinbefore described in relation to the joints of scissors, arc
with the necessary modifications applicable to surgical instruments, and the like.
Having thus particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is or may be carried into practice, I declare that
what I claim is :-
1st. In the manufacture of scissors, shears, surgical and other like instruments,
the attachment of the blades to the shanks and bows or other form of handle by
means of a mechanical joint or junction, in which one part fits into the other part,
and are commonly known as "he and she" either without or in combination with
cement, solder, one or more rivets, pegs screws, or other auxiliary means, substan-
tially as hereinbefore described, and as illustrated in Fig. 1, that is with a she
joint of any desired configuration in the blade, or wrought part of the instrument.
2-In scissors and the like, the fitting together of the parts A, B, when the
"she" portion is in B, by means of a circular or semicircular recess or recesses,
whether made by casting or mechanically, or by a combination of these methods as
shown Fig. 2, B1, substantially as hereinbefore described and illustrated.
3-In surgical instruments or parts of such instruments that have hitherto been
made of one piece of metal, or of different metals (such as steel and iron) welded
together, the fitting and joining rigidly together of separately made parts by means
of he and she joints of any desired configuration, and either in conjunction with, (or
not) the auxiliary means as herein before described.
4-In scissors, shears and surgical instruments the combination of "he and she "
joints with pegs for securing same made solid with or of the same continuous metal
as, one or other of the parts to be joined.
5-Manufacturing the outside longitudinal edge of scissors and shears with a saw
edge, or with any combination of knife, file and saw edges, substantially as herein-
before described and shown.
6-In scissors and shears, constructing the blades so that when shut, the cutting
edge of one blade will project past the back of the other blade, so that it can be
used for cutting purposes, like a knife.
7-Fitting together the several parts of scissors, shears, and surgical or other
like instruments, by the combination of mechanically fitted and cemented "he and
she" joints, substantially as hereinbefore described.
8-Fitting together the several parts of scissors, shears, and surgical or other
like instruments, by the combination of mechanical joints, as herein before described,
with the process of electric welding applied to the said joints.
