Improvements connected with Tailors' and other like Shears and
Scissors.
I, FRITZ WEINTRAUD Junior of the firm Weintraud Sons & Co. 1, 2, and
3 Cripplegate Buildings, London, Warehouseman, 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 :-
This invention relates to certain detail improvements connected with tailors and
other like shears and scissors, the object being to ensure a perfect cut for the full
length of the blades, the blades having a drawing in action on the fabric while the
blades are closing.
For the purpose of my invention, and as will be understood by the following
description when read in conjunction with the annexed drawings, Figure 1 of which
is an elevation looking on the right hand side of a pair of shears. Figure 2 a
similar view looking on the left hand side, and Figure 3 a plan or top elevation.
A, B, are the two blades pivoted at C. The blade A is slotted in the shoulder D,
and the socket cap E of the pivot pin F fixes a spring blade G in close contact, the
shank of the spring being secured by a screw H to the neck of the blade B.
The shoulder of the blade B has a link I affixed at I' near the upper part just
behind the pivot pin F, the opposite end of the link I being connected to a
projection J of the neck K of the blade A. with free action of the link for moving
over the arc of the circle in proportion to the distance the two blades are
separated.
The position and action of the link I is such that during the opening of the
blades, the blade B is drawn backwards, the pivot pin F riding backwardly in the
slot of the blade A, and in the closing operation the blade B moves forward to
engage the fabric, and prevent it being pushed forward by the edges of the blades
when first touching it, as is usual with ordinary shears and scissors.
The direction of cut will be clearly understood by the dotted lines represented
at Figure 4, in which the line a, b, shows the arc of the circle described in opening
and in closing ordinary shears and scissors from a fixed pivot, while the line c, b,
represents the arc of the circle described by the movement of my improved arrange-
ment of connecting one blade to the other on a movable pivot, this movement being
effected from the pivot L of the link I, the pivot F and slot M acting as the guide
by which the blades are held together.
C
It will be seen by the dotted line cb that the point of the blade B moves eccen-
trically from c to b, in the closing operation.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
―
1. The construction of tailors and like shears and of scissors with a slot in the
shoulder of one blade for the joint pin of the other blade to move in and with a link
joining the two blades to obtain a reciprocating motion of one blade to the other in
the opening and closing operation as set forth and substantially as shown by the
annexed drawings.

page_text: 2. The particular arrangement and the position of the parts by which a recipro-
cating motion of shear and scissor blade or blades can be produced as described and
shown in the annexed drawings.
