PROVISIONAL SPECIFICATION.
Improvements in Shears or Scissors.
I, ELI BAILEY, of Keokuk, County of Lee, Iowa, U.S.A., Shears and Scizzors
Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of shears or scizzors in which a lever is
applied to the pivot pin, one end of which rests upon one of the blades and the
other end is provided with means for adjusting it so as to bind the two blades
together. The object of the invention is to provide the lever with simple means
for securing it to the pivot pin.
For this purpose the pivot pin is provided at one end with a head and at the
other end with a perforation. The lever, preferably made of spring steel, is made
with an eye at about the middle to take over the perforated end of the pivot..
One end of the lever is turned down and bears against a blade of the scissors
forward of the pivot, and the other end is provided with a recess to receive the
inner end of a thumb screw that is passed through the handle part of a blade back
of the pivot. To the back end of the lever near the set screw is pivotted one end
of a hook or lever the other end of which engages in the perforation of the pivot
and thus holds the lever in engagement with the pivot. Each blade is provided
with a recess partly surrounding the hole in which the pivot fits and back of these
recesses are semicircular raised bearing surfaces for the two blades.

I, ELI BAILEY, of Keokuk, County of Lee, Iowa, U.S.A., Shears and Scissors
Maker, 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 that class of shears or scissors in which a lever is applied
to the pivot pin, one end of which rests upon one of the blades and the other end
is provided with means for adjusting it so as to bind the two blades together.
The object of the invention is to provide the lever with simple means for securing
it to the pivot pin and a device which will always accompany the lever and not
be liable to be lost.
For this purpose the pivot pin is provided at one end with a head and at the

page_text: other end with a perforation. The lever preferably made of spring steel, is made
with an eye at about the middle to take over the perforated end of the pivot.
One end of the lever is turned down and bears against a blade of
the scissors forward of the pivot, and the other end is provided with
a recess to receive the inner end of a thumb screw that is passed through the
handle part of a blade back of the pivot. To the back end of the lever near the
set screw is pivotted one end of a hook cr lever the other end of which engages
in the perforation of the pivot and thus holds the lever in engagement with the
pivot. Each blade is provided with a recess partly surrounding the hole in which
the pivot fits and back of these recesses are semicircular raised bearing surfaces
for the two blades.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of drawings, of which,
Figure 1 shows in elevation a pair of shears or scissors with my invention
applied.
Figure 2 is an enlarged detail side view.
Figure 3 is an enlarged transverse section taken on line III III, Figure 1.
Figure 4 is a detail view showing the central part of one of the blades, and
Figure 5 is a similar view showing the central part of the other blade.
Referring to the drawings, 1 represents one of the blades of the shears or scissors,
and 2 the other blade. 3 represents the pivot-pin, provided at one end with a
head 4 and at the other end with a perforation or hole 5. 6 represents a lever,
preferably made of spring-steel, and which is provided with a perforation to
receive the hole end of the pin 3. One end of this lever is turned down, as shown
at 7 Figure 2, and bears against the blade 2 forward of the pivot 3. The other
end of the lever is provided with a recess 8 to receive the inner end of the thumb-
screw 9, that is passed through the handle part of the blade 2 back of the pivot.
I have shown my invention applied to a pair of shears or scissors having the
raised hearing-surfaces, and I have shown in the drawings one of these bearing-
surfaces extended forward of the pivot.
10 represents a hook pivoted to the lever 6, preferably by having an inturned
efd 11 riveted in an opening formed in the lever, as shown in Figure 2. The
point of this hook is adapted to fit in the perforation 5 of the pin 3, and thus hold
the lever 6 into engagement with the pin.
When it is desired to separate the blades to clean or sharpen them, the hook 10
is simply swung back on its pivot out of engagement with the perforation 5 and
remains connected to the lever, so that there is no danger of its becoming mislaid
or lost, and the body of the hook forms a convenient leverage, against which the
finger may be pressed to disengage the point of the hook from the pin. After the
blades have been cleaned or sharpened, the pivot-pin is slipped in place, the lever
applied, the hook caused to engage the perforation in the pin, and the set-screw 9
tightened to give the proper friction between the blades.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is:―
1. In a pair of shears or scissors, the combination with the blades of a pivot-pin
or pintle provided with a perforation, a lever adapted to fit over the pin and to
bear at one end against one of the blades forward of the pin, means for adjusting
the other end of the lever, and a hook pivoted to the lever and parallel therewith
and the point of which is adapted to enter the perforation in the pin, substantially
as set forth.
2. In a pair of shears or scissors, the combination of the blades, a pivot-pin
provided at one end with a perforation and at the other end with a head, a lever
adapted to fit over the pin, a set-screw for tightening one end of the lever, and a
hook arranged parallel with the lever having an inturned end riveted into a

page_text: perforation in one end of the lever and the point of which is adapted to fit in the
perforation of the pin, substantially as set forth.
Dated this 4th day of May 1898.
