PROVISIONAL SPECIFICATION.
Improvements in Scissors, Shears, and other like Cutting
Instruments.
I, CHARLES LECOLLIER of Nogent in the department of Haute Marne, France,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The ordinary method of jointing scissors and other like cutting instruments is
troublesome, in order to get the cutting faces of the blades of the said instruments to
lie perfectly flat upon each other, which is done by slightly cranking the shanks of
the finger bows.
My invention consists in connecting the two halves of a pair of scissors together,
by means of a spring clip joint or joints, by means of which the acting faces of the
blades of the said cutting instruments are constantly pressed together, which renders
the said instruments most efficient when in use, and also makes them easy of manu-
facture, as the blades of the two half scissors do not require to be nicely fitted, as is
common with scissors of the ordinary kind.
By the aforesaid method of connecting together the two halves of a yielding joint,
a considerable saving in the manufacture is thereby made.
Another advantage in my new or improved scissors as aforesaid, is that it does
away with callosity, which is common to constant users of scissors.
Figure 1 represents in front elevation, a scissors, provided with improvements
constructed or made according to my invention. Figures 2 and 3 represent a back
and front elevation of one of the blades, separately. Figure 4 represents a side and
edge view of the spring joint, or the yielding means for connecting the two halves
of the scissors together.
a and b are respective scissor halves, provided with all-through joints wherein
joint studs or pins e, e¹, of a yielding clip, springs and snaps, whereby the two halves
of the cutting instrument are held together by a yielding connection, and by
means of which said yielding spring clip, the acting faces of the blades are rendered
self-adjusting.
Where great rigidity is required in the scissor joints, I make one of the joint
studs or pins longer than the other, so that it passes entirely through the joint hole
in the one half, and penetrates a short distance into the hole of the other half.
Figure 5 represents another form of iny invention, and consists in carrying the
joint studs or pins at the extremities of the inner ends of finger-bow extensions.
a and b are scissor halves, with joint holes c, directed through their bolster parts,
and wherein studs or pins e, at the terminals of the arms d and d¹ of the finger bows
of the respective joints a and b, take. Thus the spring arms d and d¹, hold the
scissor halves together, by the arm d proceeding from the finger-bow of the arin a,
and the arm d¹, proceeding from the finger-bow of the other half; so that the stud
on the spring arm of one half, takes into the joint hole of the other half.
Figure 6 represents a modification of figure 5, and shows the spring arms d
with their joint studs or pins e, attachedly connected to the respective shanks of
the finger-bows, instead of making the said spring arms from continuations of
the bows.

respective halves a, b, of a pair of scissors, and with the outer extensions of the said
spring connections d, extended in the direction of the said scissor halves, and with
the extreme ends e, turned at right angles into joints or pivots, which are sprung into
the joint holes c of the respective halves.

the joint may be formed by a threaded pin, with a spring washer or
washers threaded on its outer ends, which are headed, and between which heads and
the outer faces of the scissor halves, the said springs are interposed, and form a
yielding joint.
It will be observed that the cutting faces of the scissor halves are of the same
plane between the points and the shanks of the finger-bows, whilst the said shanks
are slightly cranked or bent, so as to bring the directions of the finger-bows in the

COMPLETE SPECIFICATION.
Improvements in Scissors, Shears, and other like Cutting
Instruments.
I, CHARLES LÉCOLLIER of Nogent in the department of Haute Marne, France,
Manufacturer, 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 :-
The ordinary method of jointing scissors and other like cutting instruments, is
troublesome, in order to get the cutting faces of the blades of the said instruments, to
lie perfectly flat upon each other, which is done by slightly cranking the shanks of
the finger bows.
My invention consists in connecting the two halves of a pair of scissors together,
by means of a spring clip joint or joints, by means of which the acting faces of the
blades of the said cutting instruments, are constantly pressed together, which renders
the said instruments most efficient when in use, and also makes them easy of manu-
facture, as the blades of the two half scissors do not require to be nicely fitted, as is
common to scissors of the ordinary kind.
By the aforesaid method of connecting together the two halves of a yielding joint,
a considerable saving in the manufacture is thereby made.
Another advantage in my new or improved scissors as aforesaid, is, that it does
away with callosity, which is common to constant users of scissors.
Figure 1 of the accompanying drawings, represents in front elevation, a scissors,
provided with improvements constructed or made according to my invention.
Figures 2 and 3 represent a back and front elevation of one of the blades
separately. Figure 4 represents a side and edge view of the spring-clip joint, or
the yielding means, employed for connecting the two halves of the scissors,
together.
a.and bare respective scissor halves, provided with all through joint holes c,
wherein joint studs or pins e, e¹, of a spring or yielding clip d snap and take whereby
the two halves of the cutting instrument are held together, by a yielding connection,
and by means of which said yielding connection or spring clip, the acting faces of
the blades are rendered self-adjusting.
Where great rigidity is required, one of studs of the scissor joints, may be made
longer than the other, so that the longer one passes entirely through the joint bole
in the one half, and penetrates a short distance into the hole of the other half.
Figure 5 represents another form of my invention, and consists in carrying the
joint studs or centres, at the extremities of the inner ends of arms or extensions of
the finger-bows.
a and b are scissor halves, with joint holes c, directed through their bolster parts,
and wherein studs or pins e, at the terminals of the arms d and d of the finger bows
of the respective parts a and b, take. Thus the spring arms d and d¹, hold the scissor

the limb a, and the arm d' proceeding from the finger bow of the other half; so that
the stud e, on the arm d, of part a, takes into the joint hole of the part b, while the
stud e, on arm d', takes into the joint hole of the part a.
Figure 6 represents a modification of figure 5, the connection of the scissor parts is
made by a flat spring arm d, carrying joint studs e, at their free ends, and with their
other ends attached to the shanks of the finger bows by small screws or rivets.
Figure 7 shows another form of spring connection.
d, d, are spring connections with the lower ends coiled around the shanks of the
finger bows, of the respective halves a, b, of a pair of scissors, and other ends made
into arms with turned in ends e, and which said ends e, form pins for the joints of
the said halves.
If necessary the joint may be performed by a threaded pin, with a spring washer or
washers threaded on its outer ends, which are headed, and between which heads, and
the outer faces of the scissor halves, the said springs are interposed, and form a
yielding joint.
It will be observed that the cutting faces of the scissor halves, are in the same
plane, between the points and the shanks of the finger bows, whilst the said shanks
are slightly cranked or bent, so as to bring the directions of the finger bows in the
same plane.
Figure 8 represents a barbers' scissors, constructed according to my invention.
Figure 9 represents a front and edge view (outside), of one of the parts or limbs,
whilst figure 10 represents like views of the other part, showing the flat side of the
part.
Figure 11 represents separately, the scissor clip, which is marked d, and also
represents the same provided with a single stud or fulcrum pin e, directed inwardly
from one of branches, which fits accurately within the holes c, of both of the halves
of the scissors.
The action of the spring clip, is identically the same as described in the preceding
figures.
The junction of the blades, with the shanks of the finger hows, have shoulders ƒƒ³,
so that as the halves of the scissors rotate around the axis or axes, the pulling or
lugging of the air being cut, is avoided, and which is unattainable in scissors with
slot and joints.
9. g¹, which
I also provide the inner sides of the shouldered part, with lugs or ribs
are kind of incline planes, the tops of which, are to the cutting side of the blade, and
graduating to the plane of the other part.
By the use of these lugs, a cut is obtained corresponding to the closing of the
blades, whilst the pressure of operating, is thrown upon the levers.
These lugs have a third advantage, inasmuch that the blades admit of being hollow
ground, as shown in the section figure 8, thus imparting to the scissors, a fine edge,
which will be retained, in consequence of the gradual and progressive rise of the said
inclined lugs.
From the above description, it will be understood, that the joining of the branches
of scissors by yielding connections, allows the blades to give, to an adjusted pressure,
whilst the said branches, are held efficiently together.

uses, where an alternate
Thus, in scissors for dressmakers, tailors, and for other like
opening and closing takes place, my system of connection is highly advantageous.
Figure 12 represents a modified form of my invention.
a, b, are the branches or scissor halves, p a transverse pin, and o a milled nut,
taking upon the screwed outer end of the pin; and interposed between the blades, is
a flat spring or washer r, imbedded within a cap, to prevent rotation.
The spring washers may have one or more hold-fasts, which will take into slots in
the plate.
As a modification of this last arrangement, I may employ a coiled spring, instead
of a flat one.

page_text: 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 :-
First Uniting or connecting together the halves of scissors, or the branches of
them, by means of a spring clip, whose extremities or free ends, are provided with
studs e, el, which take and adjust themselves within holes, made within the branches
or halves of the scissors a, b, respectively, substantially as described and set forth in
gures 1, 2, 3, and 4.
Secondly-Joining or connecting the branches, by spring clips or arms d, d²,
(which are extensions of the finger bows) having studs e, e¹, which take and adjust
themselves within holes in the opposite branches of the scissors respectively, substan-
tially as, and for the purpose, as described and set forth in figure 5.
Thirdly-A yielding connection for the branches or scissor halves, consisting of
flat springs d, d', with studs e, e¹, at their free ends, (as in figure 6) or coiled
springs d, d', with their upper ends, made into arms, with their terminal ends, turned
inwardly into pivot centres e, substantially as and for the purpose, as described and
set forth in figures 6 and 7.
Fourthly:Joining or connecting the branches of scissors, by a spring clip, as
described in figures 8, 9, 10, and 11, or connecting or joining the said scissor blades
or parts, substantially as set forth in figure 12.
:-
Fifthly The combination with the spring clips, as herein described, of the
concentric junction shoulderings f, and inclined lugs or ribs g, whereby a progressive
tension, and an elastic mount in the holding together of the branches or parts, is
obtained, substantially as described and set forth in figures 8 to 12.
Sixthly-The combination with the spring clips or means as described, of concentric
shoulderingsf, (struck from the pivot centre) whereby the pinching or lugging of
hair, when being cut, is avoided, substantially as described and set forth.
==
Seventhly Making the branches, and concaving the blades of the interchangable
scissor halves, by dies and pressure, and tempering the same, by the same means,
substantially as described and set forth.
Dated this 26th day of February 1890.
