page_text: I, GEORGE WILLIAM ELLIOTT, The Elms, Coal Aston, Dronfield, Derbyshire, Mining
and Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
Scissors, shears and the like instruments have hitherto been made with their joint
midway between the back & the cutting edge of each blade so that they have a
shearing action only.
In this improvement the joint is not in the centre of each blade.
In one blade the joint is nearer in a line with the cutting edge than with the back,
and in the other blade it is nearer in a line with the back than with the cutting edge.
The distance the joint may be away from the centre of each blade may be varied as
desired.
This arrangement of joint gives a drawing as well as a shearing action to the blades,
the drawing action being in the direction of the length of the blades, and thus
enabling them to sever material with greater ease, and of greater thickness than
possible with those of ordinary construction.
When it is desirable to give a comparatively long drawing action to the blades, in
addition to the joint on which the blades swing it may be preferable to perforate the
blades at or near the usual position for the joint, one blade having a hole, and the
other a radial slot in the direction of the length of the blade, the radius being
the distance from the centre of the joint to the slot.
A curved plate having two holes in it, the same distance apart as those in the
blades, is placed with its round side against the blade with the slotted hole, and the
set-screw, bolt, or rivet forming the joint, passes through one of its holes, and an
additional rivet, bolt, or set-screw passing through the other hole and the slot and
hole in the blades.
In the case of hand sheep-shears and similar instruments, the drawing action of the
blades is obtained by connecting the two halves of the shears by a link, one end being
hinged under the handle at the end nearest the blade, and the other end hinged
under the other handle at the end nearest the spring which forms the fulcrum of the
shears.
Í, GEORGE WILLIAM ELLIOTT, of the Elms, Coal Aston, Dronfield, in the County
of Derby, Mining and Mechanical Engineer, do hereby declare the nature of this
[Price 8d.]

page_text: invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Hitherto scissors and shears and the like instruments have been made with their
joints midway between the back and the cutting edge of each blade, so that they have
a radial action only. By my improvement I remove the joint out of the centre to one
side of the blades to any desired distance transversely and by the new position of
joint I obtain a swinging, sliding or drawing movement in addition to the usual
cutting action of the blades, such additional motion being in the direction of the
length of the blades thus enabling them to sever material with greater ease and of
greater thickness than is otherwise possible.
When it is desired to give a comparatively great longitudinal action to the blades
I use an additional rivet bolt or screw which I place through the blades, preferably at
or near the ordinary position for the ordinary pivot, a plain hole being made in one
blade and in the other blade a corresponding slot extending in a radial direction and
curved to the radius or distance from working pivot to the said additional bolt, also
outside of each blade I place a curved plate having holes therein to receive the pivot
and the bolt so that said plates operate as springs and with the additional bolt tend
to keep the cutting faces of the blades in close contact and so secure firm uniform
cutting action.
In the case of hand sheep shears a similar drawing action may be obtained by
connecting the two halves of such shears by a plain link one end being hinged under
one side of handle near the blade and the other end hinged under the other side near
the spring bow which forms the fulcrum of such shears."
That my invention may be more clearly understood I will now further describe the
same by reference to the drawings annexed hereto, wherein :-
Fig. 1 represents a pair of scissora. with blades closed pivot or joint being
at F. Fig. 2, represents a pair of shears having also additional bolt and side spring
plates, blades being in open position. Fig. 3, is an inside view of one blade B showing
relative position of pivot hole F and of radial slot C. Fig. 4, is a sectional view upon
line x, x, of Fig. 2. Fig. 5, illustrates application of link L to sheep shears to secure
longitudinal motion.
In practice I proceed as follows: The back or upper blade B is forged or formed
with an enlargement on its upper edge for the purpose hereinafter stated, the lower
blade B is likewise formed with a corresponding projection above its cutting edge,
such projections may be of any desired extent, and their object is to receive the pivot
holes F for joint pin F¹ or fulcrum of blades, the said pivot being in all cases placed
above the line of the cutting edge of the lower blade B¹, also approximately in a line
with the back edge of the upper blade B, the said positions resulting in a sufficient
compound swinging or sliding additional movement of the blades. The shanks and
bows of scissors may be bent fashioned or formed in any convenient manner.
For large scissors and tailors shears, or when a considerable longitudinal action of
the blades is desired, I use an additional screw pin C' preferably fixed in the
blade B¹ and sliding in a curved slot C cut in the blade B as shewn Figs. 2 and 3,
and outside of each blade I place a curved spring plate P, having holes therein
through which the pivot F1 and the screw pin C, Fig. 4, are secured so as to
effectually neutralise any tendency to separation of the faces of the blades when
cutting thick or hard materials.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1st. In scissors and tailors shears the method and means of obtaining a compound
longitudinal and radial shearing action by pivotting the blades at a point above or
to one side of the cutting line of such scissors, substantially as herein set forth.
2nd. In scissors and tailors shears having the pivot out of the centre of the blades
the combination therewith of a radial slot in one blade a plain hole in the other

page_text: blade a screw or pin passed through both blades to afford additional support to such
blades, substantially as described.
3rd. In scissors and tailors shears having the pivot out of the centre of the blades
a radial slot in one blade a plain hole in the other blade a screw or pin passing
through both blades in addition to the pivot pin the combination therewith of spring
side plates all substantially as described and for the purposes specified.
