PROVISIONAL SPECIFICATION.
Improvements in Scissors or Shears.
We, JAMES HALL SYKES, of 7, Lune Street, Preston, Dentist, and HERBERT
FINLAY SWINDLEHURST, of 5, Fox Street, Preston, Engineer, both in the County
of Lancaster, do hereby declare the nature of this invention to be as follows:-
This invention relates to scissors or shears, and has for its object certain
improvements which will now be described.
În carrying our invention into effect, we form our scissors or shears with two
blades pivoted together that cut from opposite sides against an object placed
between them. One of these blades however is made double, that is to say, it is
formed with two blades placed face to face with a narrow space between them,
and in this narrow space is pivoted the single blade that cuts from the opposite
side. The double blade therefore acts as a guide for the single one. One of the
blades of the double blade, is a little broader than the other one, this broader
blade acting in conjunction with the single blade as the cutting edge of the
scissors, while the other acts mainly as a guide which keeps the single blade in
close contact with the cutting edge, so that even if the rivet be slack the scissors
will always cut well. Another reason for making the cutting blade broader than
its adjacent one, is to prevent the cloth or other material that is being cut, getting
doubled between the two blades. There is preferably a through passage right
between the double blade, so that any matter that in cutting may accumulate
between them can easily be forced out by any suitable instrument.
It will be seen that by this invention a great improvement is effected as even if
the rivet gets slack, that occurrence will not interfere with the good cutting
qualities of the instrument, a very great desideratum.

FINLAY SWINDLEHURST, of 5, Fox Street, Preston, Engineer, both in the County

the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
-
This invention relates to scissors or shears, and has for its object certain
improvements which will now be described.

page_text: The invention will be understood from the following description, reference being
had to the accompanying drawings, in which,
Figure 1 is a view of a pair of scissors made in accordance with our invention;
Figure 2, the parts of the scissors separated from each other.
Referring to these figures, we form our scissors or shears with two blades A
and B pivoted together, that cut from opposite sides against an object placed
between them. One of these blades A however is made double, that is to say,
it is formed with two, blades A and a placed face to face with a narrow space C
between them, and in this narrow space is pivoted at D the single blade B that
cuts from the opposite side. The double blade A a therefore acts as a guide for
the single one B. One of the blades A of the double blade is a little broader than
the other one, this broader blade acting in conjunction with the single blade
as the cutting edge of the scissors, while the other a acts mainly as a guide which
keeps the single blade in close contact with the cutting edge, so that even if the
rivet D be slack the scissors will always cut well. Another reason for making
the cutting blade A broader than its adjacent one a is to prevent the cloth or
other material that is being cut, getting doubled between the two blades. There
is preferably a through passage right between the double blade, so that any
matter that in cutting may accumulate between them can easily be forced out by
any suitable instrument.
It will be seen from Figure 2 that the blade a is separate from the blade A and
is rivetted thereto at E, lugs F being provided to separate the two blades
sufficiently to leave a space between. We do not however confine ourselves to this
exact construction.
It will be seen that by this invention a great improvement is effected as even if
the rivet gets slack, that occurrence will not interfere with the good cutting
qualities of the instrument, a very great desideratum.
In the drawings the guiding blade a is shown the same length as the other
blades A and B. It is obvious however that if desired this blade a need not be
made the full length of the other blades.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
wo claim is:
1. The improvements in scissors or shears which consist in forming one of the
blades double, that is to say with two blades placed face to face with a narrow
space between them, and in this narrow space pivotting a single blade having an
opposite cutting edge to the double blade, whereby the double blade acts as a
guide for the single one, substantially as and for the purposes described.
2. The general combined arrangement and construction of parts forming our
improved scissors or shears substantially as set forth.
