PROVISIONAL SPECIFICATION.
Improvements in Scissors, Shears, and the like.
I, HENRY PARKER of 3 Dearman Road Sparkbrook in the County of Warwick
Assurance Superintendent, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object improvements in scissors, shears, and the like and
consists in making the cutting blades of the aforesaid articles and other like cutting
instruments in such a manner that their cutting edges are always kept keen or
sharpened.
In carrying my invention into practice as applied to a pair of ordinary scissors I
attach to one of the cutting blades near to the joint, or between the joint and the
loop a double quadrant, or, a semicircular strip of sheet steel forming a spring, or
the said cutting blade and the spring may be made in one part.
The function of the said spring is to keep the two cutting blades of the scissors
pressed firmly together, this is effected by the lateral movement of the inner side of
the spring pressing against the side of the opposite cutting blade, thus keeping the
two cutting edges constantly grinding together and maintaining the keenness of their
edges.
:
Or I may modify the form or position of the spring on the scissors blade, to
produce the same effect.
My said invention may be applied to shears or other like cutting instruments in
the aforesaid manner without departing from the nature or object thereof.
Dated this 16th day of July 1891.

COMPLETE SPECIFICATION.
Improvements in Scissors, Shears, and the like.
I, HENRY PARKER, of 3 Dearman Road Sparkbrook in the County of Warwick,
Assurance Superintendent do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention has for its object improvements in scissors, shears and the like and
consists in making the cutting blades of the aforesaid articles and other like cutting
instruments in such a manner that their cutting edges are always kept keen or
sharpened.
In carrying my invention into practice as applied to a pair of ordinary scissors, I
attach to one of the cutting blades near to the joint, or between the joint and the
loop a double quadrant or a semicircular strip of sheet steel forming a spring.
The function of the said spring is to keep the two cutting blades of the scissors
pressed firmly together, this is effected by the lateral movement of the inner side of
the spring pressing against the side of the opposite cutting blade, thus keeping the
two cutting edges constantly grinding together and maintaining the keenness of
their edges, or I may modify the form or position of the spring or the scissors blade
to produce the same effect. My said invention may be applied to shears or other
like cutting instruments in the aforesaid manner without departing from the nature
Price 6d.

page_text: or object thereof. I will now proceed with reference to the accompanying drawings
to describe the manner in which my invention may be performed.
Figures 1 and 4 represent a front elevation Figures 2 and 5 an end elevation
Figure 3 a side elevation of a pair of scissors made in accordance with my inven-
tion.
In Figures 1, 2 and 3 a pair of scissors are represented in their normal or closed
position with. a double semi-circular steel spring attached to the cutting blade c
either by soldering, brazing or fixing with rivets Figure 3 represents a side elevation
of the scissors showing the double semi-circular spring . closed or compressed by
the raised part e. of the cutting blade d. pressing against the inner part of the
spring which is also shown at Figure 2.
In Figures 4 and 5 the scissors are represented opened which allows the inner
part of the spring b³ to expand laterally as shown in at Figure 5. thus the constant
opening and closing of the scissors blades, causes the raised part e of the blade d to
press against the inner part of the spring which in like manner presses the cutting
surface of the blade d, and by the constant grinding of the two together maintain
the keenness of their edge.
In Figures 6 and 7. I show modifications of the spring b. detached from the
scissors blade c.
Figure 8. shows a similar spring corrugated instead of being made flat.
Figure 9. represents a spring made from steel wire instead of sheet steel.
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 :-
The improvements in scissors, shears and the like in which the combination of a
double acting spring operating in the manner herein set forth for the purpose of
grinding or sharpening the two cutting blades substantially as herein described and
illustrated in the several figures of the accompanying drawings.
