PROVISIONAL SPECIFICATION.
An Improvement connected with Scissors, Shears, and the like.
I, ERNEST JAMES COURT, of 10 Duke Street, Manchester Square, Middlesex,
Watch Maker, do hereby declare the nature of this invention to be as follows:-
:-
The object of this invention is to provide an appliance to scissors, shears, and
the like, whereby the edges of blades are kept in close contact during the move-
ment of the blades, so that better cutting is effected, the pivot pin never working
loose.
For the purpose of my invention, I employ a slightly arched flat springy plate,
which has a slot in it for half its length or nearly so for engaging under one head,
or in recesses, or notches of the pivot pin, which is loosely fitted in holes in the
blades and by its springy nature keeps the two blades in close contact.
The pivot pin may be of square or approximate shape at its upper part and fit a
similar shaped hole in one blade of the article, so that the spring plate engaging
under the head would not shift its position when the article is in use.
If the pivot
pin be cylindrical the whole of its length, a small slot may be made in the plate for
engaging in a projecting pin on one blade of the article, or a groove or grooves cut
in the blade for the ends of the spring plate to rest in will prevent the spring plate
moving when the article is in use, but I do not limit myself to any particular shape
of pin or means for keeping the spring plate in position when the article is in use,
the chief feature of my invention being the arched flat springy plate for keeping
the cutting portions of the two blades of scissors, shears, and the like in close
contact, whereby cleaner and better cutting is effected, the article wears longer and
does not require sharpening or setting so often.

COMPLETE SPECIFICATION.
An Improvement connected with Scissors, Shears, and the like.
I, ERNEST JAMES COURT, of 10 Duke Street, Manchester Square, Middlesex,
Watch 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 :-
The object of this invention, is to provide an appliance to scissors, shears, horse
clippers, and the like, whereby the edges of blades are kept in close contact during
the movement of the blades, so that better cutting is effected, the pivot pin never
working loose.
For the purpose of my invention, I employ a slightly arched flat springy plate,
which has a slot in it for half its length, or nearly so for engaging under one head,
or in recesses, or notches of the pivot pin, which is loosely fitted in holes in the
blades and by its springy nature keeps the two blades in close contact.
The pivot pin may be of square or approximate shape at its upper part and fit a
similar shaped hole in one blade of the article, so that the spring plate engaging
under the head would not shift its position when the article is in use.
If the pivot
pin be cylindrical the whole of its length, a small slot may be made in the plate
for engaging in a projecting pin or screw on one blade of the article, or a groove

page_text: or grooves cut in the blade for the ends of the spring plate to rest in will prevent
the spring plate moving when the article is in use. I do not limit myself to any
particular shape of pin, or means for keeping the spring plate in position when the
article is in use, the chief feature of my invention being the arched flat springy
plate for keeping the cutting portions of the two blades of scissors, shears, horse
clippers, and the like, in close contact, whereby cleaner and better cutting is
effected, the article wears longer, and does not require sharpening, or setting 50
often.
My invention will be clearly understood by reference to the annexed drawings.
Figure 1 is an elevation of the springy arched plate with the slot for engaging
the head of the pin running from the end of the plate to about the middle.
Figure 2 is an elevation of the springy arched plate with the slot made in it and
terminating in a hole, through which the head of the pivot pin is passed and the
plate then moved along for the slot to pass under the head.
Figure 3 is an elevation of the springy arched plate with a slot in the centre of
oval shape for engaging an oval head of the pivot pin. The plate in this instance
is put over the head of the pivot pin, and then turned a quarter round to occupy
its proper position, the narrow sides of the slot engaging under the head of the
pivot pin.
Figure 4 shows the pivot pin having a tapered portion.
Figure 5 shows the pivot pin having a square portion near one end for engaging
a similar shaped hole in one blade and keeping the plate in position without the
use of the screw or pin.
Figure 6 is an elevation of a pair of scissors showing the spring plate in the
position it occupies and held by screw or pin engaging recess in one end of plate.
Figures 7 and 8 are side elevations of a pair of scissors showing the spring plate
in position but with the pivot pins of different shape, that of Figure 7 being
tapered at one part, the pin of Figure 8 being made with a square at one part for
engaging the hole of one blade of the scissors and to move with it.
Figure 9 is an elevation of a modified spring plate of cup shape having radial
slits, the slot terminating in a hole, as at Figure 2.
A, spring plate.
B, slot in spring plate.
C, recess in end of spring plate for engaging pin or screw to keep plate in
position.
D, pivot pin.
E, screw or pin for holding plate A in position when cylindrical shaped pivot pin
is used.
Having now particularly described and ascertained the nature of this inven
declare that what I
tion and in what manner the same is to be performed
claim is :-
Providing the pivot pins of scissors, shears, and the like, each with an arched
flat spring plate having a slot in it for engaging under a head of said pivot pin, as
and for the purposes described, and in the manner illustrated by the annexed
drawings.
