FOLDING SCISSORS
Berkeley Julian Florian, Plantsville, Conn.
Application March 1, 1937, Serial No. 128,308
8 Claims.
This invention relates to scissors and shears but
more especially to improvements in folding scis
sors which can be adjusted either into- extended
operative condition or be folded up into small
5 compass, and the invention has for its main ob
joct to provide an improved scissors of this type
which may be of any desired size or design.
It is also an object of the invention to provide
a durable folding scissors instrument which can
10 be conveniently and safely carried in the pocket
of a garment; which will be of simple and effi
cient construction, and which can be produced
at a low cost.
To these ends I have provided an improved
folding scissors instrument constructed and op
erating as set forth in the following description,
the several novel features of the invention being
separately pointed out and de?ned in the claims
at the close thereof
In the accompanying drawing:

'
Figure 10 shows the scissors of Figs. 1 and 2
in another folded condition.
Figure 11 is a top plan view of the scissors
shown in Fig. 10.
Figure 12 illustrates one form of pivotal con
nection by which the several parts of the scis
sors are fastened together.
Figure 13 shows an alternative form of piv
otai connection.
The embodiment of my invention illustrated in
Figs. 1 to 12, inclusive, comprises two scissor or
cutting members 9, 9 each of which includes a
blade-section it] and a handle-section II, the
two blade-sections being duplicates and the two
handle-sections being
duplicates.
(01. 30-255)
blanking dies and one forming die, the latter
being employed to bend the handle-section blanks
into their ?nal shapes. Or the bending of the
handle-section may be effected by the same die
mechanism by which it is cut out.
Cl
All four of these sections are pivotally con
nected together by a single pintle or rivet I2.
That is to say,. the single pintle or rivet l2’not
only pivotally connects the two scissor members
9, 9 but it also pivotally connects the two sections 10
of each of said members.
As shown in Figs. 4 and 5 each handle-section
It comprises a shank portion l8 formed at its
one end with an eye or ring 13 for the reception
of a ?nger of the hand by which the instrument
is operated, the inner marginal portion of this
eye being rounded inwardly as shown at M, and
at its opposite end with an aperture l5, Fig. 4,
to receive the pintle I2 and with a longitudinal
slit it which provides a resilient spring ?nger
ll to co-operate with the hub of the blade sec
tion l0 that is associated with said handle-sec
tion;
As shown in Fig. 5 the shank E8 of each handle
section is of angle-iron shape in cross-section 25
and this angular shape provides an inwardly pro
jecting ?ange l9 which extends throughout the
greater portion of the length of the spring ?nger
if and provides a stop shoulder 20 adjacent to
the free end of said ?nger to co-operate with a
shoulder 2!, Figs. 3 and 8, provided upon the hub
of the blade section l0 that is associated with said
handle section.
At the end thereof that is in proximity to the
?nger-receiving eye l3, viz., at its outer end, the
?ange I9 of each handle-section H is made with
a lug extension 22, Figs. 1 and 11, to co-operate
with the blade-section of the other, or opposite,
scissor member as presently to be described.
In order to impart the desired strength and
resiliency to the spring ?nger ll of each handle
section the latter is spring tempered and because
of the angular cross-sectional shape of said ?n
ger, and the proximity of the inner end of slit
IE to the ?ange l9, practically all of the flexing
of ?nger ll toward and from pivot aperture I5
Fig. Li, will be localized adjacent to said inner end.
Thus the opposite end portion of ?ange i9 that
is adjacent to aperture I5 is not distorted from
its ?at shape by movement thereof toward and
from said aperture.
When the several parts of the scissors are as

ingiy against the hub portion 23, Figs. 3 and 8,
edges of the blade sections, prevent further rela
of the blade section If! however the latter may be
tive movement of the latter. Continued move
ment of the handle-sections thereafter moves
them relatively to the closed blade sections until
adjusted relatively to the handle-section.
The hub portion 23 of each blade-section l0,
Figs. '7 and 8, is formed with an aperture 24 to
receive the pintle-rivet l2 while its periphery is
made with two tangential ?at surfaces 25 and 26,
the former surface 25 being disposed at one side
of aperture 24 adjacent to shoulder 2| and the
10 surface 26 being disposed at the opposite side of
said aperture 24, said two surfaces being also
disposed obliquely relatively to each other as
shown in Fig. 7. Between these two flat surfaces
the periphery of said hub portion is made arcuate
15 and concentric with respect to aperture 24 as
shown at 27.
When the blade section occupies extended posi
tion relatively to its handle-section the shoulder
2| thereof abuts the end of ?ange l9 at 20 while
said ?ange bears ?atwise against the ?at sur
face 25 of the blade section thereby to yieldingly
hold the latter against closing movement rela
tively to the handle section. Thus the ?ange IQ
of each handle-section cooperates with the blade
25 section thereof to perform a double function in
addition to a third function to be referred to
presently.
When the two members 9 of the scissors are in
operative condition as shown in Fig. 1, relative
swinging movement of the two members in a
direction to close the blade section together is
limited by the engagement of bosses 3! which
project from the inner faces of the blade sec
tions, each with the cutting edge of the opposite
blade section. These bosses are struck up from
the material from which the blade sections are
made by the blanking die and therefore each
boss is integral with its blade section and cannot
work loose. Swinging movement of the two han
40 dle sections in the opposite direction ?rst opens
the blade sections to their fullest extent as shown
the shoulders 28 at the ends of the ?anges l9
abut the shoulders 2! of the blade sections which
is the limit of adjustment of the two handle
sections in that direction. The scissors is then in
operative but closed condition.
While being thus adjusted the engagement of 10:
the ?ange portions E9 of the spring
H
with the ?at surfaces 26 causes each blade-sec
tion to move with its handle-section as the two
handle-sections are moved apart from the posi
tions shown in Fig. 2 until the movement of the 15
blade sections toward each other is arrested by
the stop bosses 3i, Fig. 1, and thereafter the en
gagement of shoulders 29 and 2i occurs while the
blades are closed which prevents further move
ment of the handle-sections. It will be clear
that when a blade section occupies the position
shown in Figs. 2 and 3 the engagement of the
?ange IQ of spring ?nger E? with the ?at surface
28 of the blade section yieldingly opposes open~
ing movement of the latter, while further move 25
ment of the blade section toward the eye of its
handle-section is prevented by the elevation 28
of the blade.
The pintle rivet I2 is made at one end with a
head as shown while the opposite end portion of
its shank is made tubular and is upset as shown
to permanently secure the parts together. Be
fore upsetting the end of the shank of the pintle~
rivet a spring washer 32 is placed in position on
the projecting end of the shank that is to be 35
upset.
In Fig. 13 I have illustrated an alternative form
of pivotal connection wherein each handle-sec
tion il is pivotally and permanently connected

rivet l2 in the same direction brings the two
scissors members in this fashion a solid rivet 35
?nger eyes 13 into register as shown in Fig. 2, the
engagement of the outer free end portions of the
blades with the lugs 22 of flanges l9 together
with the engagement of an elevation 28, Figs. 7
and 8, on the hub of each blade section with its
two members and upset as shown. With this
construction illustrated in Fig. 13 the two sections of each scissors member are pivotally con50
nected by a rivet or pintle other than that which
?ange i9, preventing further relative movement
of the two handle-sections in that direction. The
elevation 28 on the hub of each blade section
is made of su?icient height to co-operate with
its ?ange I9 as a stop as described. That is, the
radial distance of elevation 28 from the axis of
the aperture 24, Fig. '7, is materially greater than
the radial distance between said axis and the
arcuate surface 21.
After each blade blank is produced from sheet
steel as above described it is ground away upon
its outer face to bevel the same as shown at 29,
Fig. '7, along its inner cutting edge 30.
In adjusting the parts from their folded up
inoperative positions shown in Fig. 2 the two
handle-sections are swung apart on the pintle
rivet [2 to the extent of nearly 180 degrees.
When the scissors instrument is viewed as in Fig.
2 the nearest handle-section i! would be swung
downwardly and the further handle-section up~
wardly to the extent described. The ?rst effect
of this relative movement of the handle-sections
is to close the two blades together until the bosses
