PROVISIONAL SPECIFICATION left by the said Louis Auguste Pichon
at the Office of the Commissioners of Patents on the 6th November 1877.
LOUIS AUGUSTE PICHON, of Paris, Rue des Saussaies, No. 14.
SCISSORS WITH JOINTED RINGS, ALSO APPLICABLE TO FORCEPS."
"IMPROVED
Scissors and forceps of ordinary construction are often inconvenient for fitting
into sheaths or cases, on account of the rings or loops by which they are held.
My present Invention consists in obviating this difficulty by constructing the
rings or loops with joints, in such manner that when not in use they will fold
together, so as to occupy no greater space in the width than the other part of the
scissor or forceps, while when the loops are expanded for use they are as rigid as
ordinary loops. For this purpose the loops are constructed with four hinge joints,
one at the junction of the outer part of the loop with the shank, one on each side
of the loop at about the middle thereof, and one at the bottom of the loop, so that
on pressing the two sides of the loop together, they will fold inwards against each
other; the side joints are by preference made with shoulders outside, so that when
opened out to the required distance the joints become rigid, and in order to avoid
unevennesses at the joints they are made with a mortice on the one part fitting on to
a tenon on the other part, so that the side surfaces are all flush..
y
For convenience the bottom joint may be made double; that is, the meeting ends
of the two lower links may be made with mortice joints which are connected
by a short tenon link.

'IMPROVED
The fixed or rigid rings of ordinary or surgical scissors and of dressing forceps
often present a certain inconvenience when a place has to be found for them in
cases, necessaries, etc. This disadvantage is remedied by providing the said rings
with a certain number of joints or hinges; the said jointed rings then fold either up
or down on themselves, and open again with equal ease. When folded or flattened
on themselves, either up or down, they take up but little room, and may easily be
inserted in the divisions or compartments intended for their reception.
The accompanying Drawing gives a clear illustration of my instruments with
jointed rings.
Fig. 1 is a front view of a pair of pocket case scissors, open; Fig. 2 is a side view
of the same.
Fig. 3 is a front view of the scissors, shut, the rings being flattened or folded
down on themselves.
Fig. 4 illustrates a pair of scissors constructed according to the Invention.
Fig. 5 is a front view of a pair of scissors, the open jointed rings of which are to
be flattened or folded in an upward direction; Fig. 6 is the same view, the rings
being flattened upwards.
On each of the arms a are jointed the links b and c, connected and jointed with
the link d. The said three links b, c, d, together with the arm form a lozenge which
can be unfolded and expanded to allow a passage for the fingers, Fig. 1. or 5, or
else closed, in order to take up little room, Fig. 3 and 6.
The links are rounded as much as possible inside to avoid the angles which would
render the handling of the scissors inconvenient.
The different links are jointed with tenon and mortise. The arm a carries a
tenon e, corresponding with the mortise f of the link b which carries at its oppo-
site end a tenon g; the end of the arm a is notched with a mortise h, to
receive the tenon of the link c, provided with a mortise j; and, lastly, the
link d carries a tenon l, corresponding with the mortise ; of the link c.
The number, shape, and dimensions of the links of which the jointed rings are
formed may be varied, and the latter made of metal, similar or different to the metal
of the scissors, or of any other suitable material; the joint rings may likewise be
modified.
Having thus fully described the said Invention, and the manner of carrying it
into effect, I would have it understood that I do not confine myself to the precise
details above enumerated, as these may obviously be modified without departing
from the principle of the Invention; but what I claim is, the application to ordinary
or surgical scissors, dressing forceps, and other instruments, of rings, with several
joints easily opening and flattening or folding at will, either upwards or downwards,
upon, or against themselves or the arms, so that the said instruments may without
any difficulty be stowed away in surgical pocket cases, travelling necessaries,
etc., substantially as above described, and represented in the accompanying
Drawings.
In witness whereof, I, the said Louis Auguste Pichon, have hereunto set my
hand and seal, this Twenty-fifth day of April, in the year of our Lord
One thousand eight hundred and seventy-eight.
