I, ARTHUR GEORGE, NEWTON 58, Infirmary Road, Sheffield in the County of
York Joiner do hereby declare the nature of my said invention for IMPROVEMENTS
IN THE CONSTRUCTION OF SHEEP SHEARS, AND SIMILAR SHEARS, to be as follows:
My invention of improvements in the construction of sheep shears, and other
similarly constructed shears relates to those shears in which the blades are made to
turn back to a convenient position for sharpening or for other purposes, and more
particularly to those joined at the bows and known as double bowed.
i
The object of the invention is to construct a simple, strong, and effective joint to
secure the parts together, and at the same time to keep the blades on the cut.
I also dispense with screws or any loose parts.
In carrying out my invention so as to accomplish the above-named objects,
I make one of the joint-ends of the bow with a fixed stud having a head similar
to a rivet head, this fixed stud is not in the centre but is placed preferably between
the centre and the edge.-In a similar position on the other side of the centre, is
the rivet hole corresponding with one in the other part of the shear, through
which the connecting rivet is secured, and upon which the blades can be turned or
rotated when required.
To engage with the headed fixed stud before mentioned, a segmental slot with
open end is formed in the opposite part of the shear to receive the neck of
the stud.
This open end slot is so arranged that the position of the blades right for cutting,
must be reversed, that is instead of being face to face, they must be sprung apart
and be back to back, before the two blades can be turned round or rotated on
the rivet.
Thus by this method of constructing the joint of shears, the blades of such shears,
can only be separated and rotated in one direction, and when closed for use they
are firmly held in position together between the "cut" and the stud.
I do not bind myself to the exact shape or configuration of the details of the
joint, as such details may be varied without altering the principle of the invention..
Dated the 8th day of December 1885.

Improvements in the Construction of Sheep Shears and
similar Shears.
I, ARTHUR GEORGE NEWTON 58 Infirmary Road Sheffield in the County of
York Joiner do hereby declare the nature of my invention for IMPROVEMENTS IN
THE CONSTRUCTION OF SHEEP SHEARS, AND SIMILAR SHEARS and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement, that is to say :-
My invention of improvements in the construction of sheep shears, and other
similarly constructed shears, relates to those shears in which the blades are made
Bo that they can be turned back to a convenient position for sharpening, or for
other purposes and more particularly to those that are joined at the bows and
known in the trade as double bowed.
And so that my invention may be clearly understood, I annex thereto a sheet of
drawings illustrating my invention in which
Fig. 1, represents a pair of shears made according to my invention.
Figs. 2 & 3, the ends of the bow which form the joint, separated.
The object of this invention is to construct a simple, strong and effective joint to
secure the two parts of the shear together, and at the same time to hold the blades
on the cut, without the use of screws or other loose appliances.
In carrying out my invention so as to accomplish the above named objects,
I make one of the ends of the bow see Fig. 2, with a fixed stud, A, having a head
similar to that of an ordinary rivet, this fixed stud is preferably placed halfway
between the centre of the end, and the edge, as shown in the drawing, and in a
similar position on the opposite side is a rivet-hole B, corresponding with one in
the other end Fig. 3, marked C-Through these two holes the connecting rivet is
passed and secured, by heading in the usual way, but so that the blades can be
turned or rotated when required.
To engage with the fixed headed stud A before mentioned, I make a segmental
open ended slot D, in the end shown in Fig. 3, to receive and work upon the neck
of the stud.
This open end slot is so arranged that the position of the blades when right for
cutting (as shown in Fig. 1) must be reversed, or sprung apart so as to be back to
.back, before they can be rotated on the rivet or joint pin and separated.
Thus by this novel method of making or constructing the joint of shears, the
blades can only be rotated or turned in one direction when it is desired to separate
them, and when closed and in position for use, they are firmly held in position
together between the "cut" and the stud, a matter of great importance.
I do not bind myself to the exact details or configuration of the parts, as it
is evident that variations may be made without altering or departing from the
principle of my invention.

page_text: Having now particularly described and ascertained the nature of my Baid
invention and in what manner the same is to be performed I declare that what
I claim is
1-The improved construction of joint for Sheep Shears and other Shears, sub-
stantially as hereinbefore described and illustrated.
2-In Sheep Shears, and similar shears, the combination of the stud A, the slot D,
and the rivet pin passing through the rivet holes B & C, for the purpose specified,
and substantially as hereinbefore described.
