PROVISIONAL SPECIFICATION.
Improvements in or connected with Shears, Scissors, Pliers, or like
Instruments.
I, ELI BAILEY, of Brantford, in the County of Brant, in the Province of
Ontario and Dominion of Canada, Manufacturer of Cutlery, do hereby declare
the nature of this invention to be as follows:
My invention relates to shears scissors or the like having an adjustment
yoke applied to their pivotal point to bind the two blades thereof together
with a requisite amount of pressure to enable the accurate working of the
implement, and my invention consists in features of novelty hereinafter fully
described and pointed out in the claims.
Fig. I is a side view of a pair of shears constructed in accordance with my
invention.
Fig. II is a cross-sectional view taken on the line II-II, Fig. I.
Fig. III is a longitudinal sectional view taken on the line III-III, Fig. I
through the portions of the blades adjacent to the pivotal point, the pivot pin
and yoke being shown in elevation.
Fig. IV is an inner face view of the pivot portion of one of the blades.
Fig. V is a detail sectional view taken on the line V-V, Fig. III.
1 designates one of the shears or scissors blades having a handle 1 and 2 is
the other blade having a handle 2".
Each blade has a flat bearing surface 4 (see Figs. III and IV) at the inner
portion, and from these flat surfaces the blades are formed with concaves 3 that
extend from said surfaces 4 to the points of the blades, the concavity continuing
to the end of each blade in conformity to the portions seen in Fig. III. The
concave 3 extends from the outer to the inner edges of each blade and said
outer and inner edges are on planes with the bearing surfaces 4, as is clearly
shown in Fig. III. By this arrangement the working of the shears or scissors is
rendered extremely accurate by reason of there being a minimum of contacting
surfaces throughout the implement.
The blade 1 has a pivot pin 5 inserted in it and extending beyond the inner
face of said blade. The blade 2 is provided with a cavity 6 that receives the
inner end of the pivot pin 5, the said pin being adapted to fit into said cavity
to a nicety to prevent play of one blade on the other. The pivot pin 5 is
provided with a shoulder 5 that limits the extent of the insertion of the pin
and it has at its outer end a rounded boss 5b. The pin is removably seated in
the blade 1 in order to allow of its withdrawal during the operation of grinding
or sharpening the blade at any time. The blade 2 has a recess 7 in its outer
face directly opposite the central portion of the pivot pin 5.
8 designates a yoke, one end of which is provided with a stud 9 adapted to
seat in the recess 7 of the blade 2. The other end of the yoke is provided with
a cavity 10 that receives and fits over the rounded boss 5 of the pivot pin (see
Fios and III).

page_text: The yoke 8 has a screw 11 attached to one of its arms, and extending beyond
said last mentioned arm. On the free end of the screw is an adjustment nut 12
whose inner end is provided with a screw-thread that engages the thread of
said screw. The nut 12 is formed with a recess 12" in its outermost portion
that receives a shouldered head 11" of the screw 11. By this arrangement the
screw 11 may be made of only sufficient length to allow the nut 12 to
be turned onto the screw 11 a sufficient distance to tighten the clamp 8 upon
the pivot point of the shears without the headed or free end of the screw pro-
jecting beyond the outer face of the nut and when the nut is loosened to allow
the removing of the clamp S for the separation of the shear blades, said nut
cannot entirely escape from the screw 11, owing to the shouldered head coming
in contact with the base of the recess 12" and limiting the turning of said nut,
thus the nut is prevented from becoming separated from the screw in which
event it might become lost or misplaced.
While I have shown and described my invention as applied to shears or scissors,
I do not limit myself to its use for this particular implement, as besides its
use in connection with shears or scissors of all kinds, it may be applied with
equal facility and advantage in the construction of pliers, forceps, surgical instru-
ments or other devices of like character.

Improvements in or connected with Shears, Scissors, Pliers, or like
Instruments.
I, ELI BAILEY, of Brantford, in the County of Brant, in the Province of
Ontario and Dominion of Canada, Manufacturer of Cutlery, 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
thereof that is to say:-
My invention relates to shears scissors pliers, or like instruments having an
adjustment yoke applied to their pivotal point to bind the two blades thereof
together with a requisite amount of pressure to enable the accurate working of the
implement, and my invention consists in features of novelty hereinafter fully
described and pointed out in the claims.
Referring to the drawings accompanying my Provisional Specification
Fig. I is a side view of a pair of shears constructed in accordance with my
invention.
Fig. II is a cross-sectional view taken on the line II-II Fig. I.
Fig. III is a longitudinal sectional view taken on the line III-III, Fig. I
through the portions of the blades adjacent to the pivotal point, the pivot pin
and yoke being shown in elevation.
Fig. IV is an inner face view of the pivot portion of one of the blades.
Fig. V is a detail sectional view taken on the line V-V, Fig. III.
1 designates one of the shears or scissors blades having a handle 1 and 2 is
the other blade having a handle 2ª.
Each blade has a flat bearing surface 4 (see Figs. III and IV) at the inner
portion, and from these flat surfaces the blades are formed with concaves 3 that
extend from said surfaces 4 to the points of the blades, the concavity continuing

page_text: to the end of each blade in conformity to the portions seen in Fig. III. The
concave 3 extends from the outer to the inner edges of each blade and said
outer and inner edges are on planes with the bearing surfaces 4, as is clearly
shown in Fig. III. By this arrangement the working of the shears or scissors is
rendered extremely accurate by reason of there being a minimum of contacting
surfaces throughout the implement.
'
The blade 1 has a pivot pin inserted in it and extending beyond the inner
face of said blade. The blade 2 is provided with a cavity 6 that receives the
inner end of the pivot pin 5, the said pin being adapted to fit into said cavity
to a nicety to prevent play of one blade on the other. The pivot pin 5 is
provided with a shoulder 5" that limits the extent of the insertion of the pin
and it has at its outer end a rounded boss 5b. The pin is removably seated in
the blade 1 in order to allow of its withdrawal during the operation of grinding
or sharpening the blade at any time. The blade 2 has a recess 7 in its outer
face directly opposite the central portion of the pivot pin 5.
8 designates a yoke, one end of which is provided with a stud 9 adapted to
seat in the recess 7 of the blade 2. The other end of the yoke is provided with
a cavity 10 that receives and fits over the rounded boss 56 of the pivot pin (see
Figs. II and III).
The yoke S has a screw 11 attached to one of its arms, and extending beyond
said last mentioned arm. On the free end of the screw is an adjustment nut 12
whose inner end is provided with a screw-thread that engages the thread of
said screw.
The nut 12 is formed with a recess 12" in its outermost portion
that receives a shouldered head 11" of the screw 11. By this arrangement the
screw 11 may be made of only sufficient length to allow the nut 12 to
be turned onto the screw 11 a sufficient distance to tighten the clamp 8 upon
the pivot point of the shears without the headed or free end of the screw pro-
jecting beyond the outer face of the nut and when the nut is loosened to allow
the removing of the clamp 8 for the separation of the shear blades, said nut
cannot entirely escape from the screw 11, owing to the shouldered head coming
in contact with the base of the recess 12ª and limiting the turning of said nut
thus the nut is prevented from becoming separated from the screw in which
event it might become lost or misplaced.
While I have shown and described my invention as applied to shears or scissors,
I do not limit myself to its use for this particular implement, as besides its
use in connection with shears or scissors of all kinds, it may be applied with
equal facility and advantage in the construction of pliers, forceps, surgical instru-
ments or other devices of like character.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In a pair of shears scissors pliers or like instrument the combination of a
yoke having its ends applied to the pivotal joint of the blades thereof, and
adjusting means applied to said yoke at a point removed from the pivotal point
of the blades; substantially as described.
2. In a pair of shears, scissors, pliers, or like instrument the combination
of a yoke having its ends applied to the pivotal point of the blades thereof, a
screw seated in said yoke at a point removed from the pivotal point of the blades,
and extending from one arm thereof through the other arm, and a nut applied
to said screw, through means of which the ends of said yoke may be contracted
to bind said blades at their pivotal point; substantially as set forth.
3. In a pair of shears scissors, pliers or like instrument the combination
with the blades thereof, of a removable pivot pin in one of said blades, the other
of said blades being provided with a cavity adapted to receive said pivot pin,
and a yoke applied to said blades at their pivotal point, substantially as described.
4. In a pair of shears scissors, pliers or like instrument the combination with

page_text: the blades thereof, of a yoke adapted to be applied to the pivotal point of said
blades, a screw seated in said yoke, a nut on said screw, said nut being provided
