Improvements in Sheep Shears.
We, PHILIP ASHBERRY of Burngreave Road, Manager, and WALTER BARNES,
of Intake Road, Ivory Worker, both of the City of Sheffield, do hereby declare the
nature of our invention to be as follows:-
-
Our improvements refer to shears having detachable blades, or blades made
separately and permanently affixed to the shanks and how.
The object of the invention is to enable the blades to be made of steel adapted
for cutting purposes, and the bow of elastic spring steel, also to avoid waste of
material and reduce the cost of manufacture.
We propose to punch the blades to form from flat steel, each blade having a short
tang with a slotted opening or mouth at the extreme end when the blade is to be
detachable, and a concaved tab to fit the inside of the shank when it is to be
permanently attached.
The shanks and bow are cut in one piece and bent, hollowed and pressed to the
desired configuration. The extreme end of each shank is doubled and flattened to
form a lug having one face in line with the centre of the shank, against which the
flat side of the blade fits and to which it is secured.
For detachable blades a slot is made in the centre of the bow shanks, to receive
the end of the tang upon the blade, and a short indented portion at the bottom
of the slot passes into the mouth of the tang before mentioned.
The screw hole through the butt end of the blade which lies against the lug at
the end of the shank, may be either slotted through one side, to avoid the complete
removal of the screw, or not as desired.
If the blades are to be permanently fixed to the shanks, a rivet is passed through
the blade and lug, and through the tang and shank.

Improvements in Sheep Shears.
We PHILIP ASHBERRY of Burngreave Road Manager, and WALTER BARNES
of Intake Road Ivory Worker, both of the City of Sheffield do hereby declare the
nature of this invention and in what manner the same has to be performed, to be
particularly described and ascertained in and by the following statement :—
Our improvements refer to hand shears having blades made separately and then
affixed permanently to the shanks and bow, or separate detachable blades.
The object of the invention is to enable the blades to be made of steel specially
adapted for cutting purposes, and the bow of elastic spring steel, and also to avoid
waste of material and to reduce the cost of manufacture.
The invention is illustrated in the annexed sheets of drawings in which like
letters of reference refer to like parts in any of the figures.

Fig. 3, end view of same.
Fig. 4, represents a blade as cut out of the flat, and the butt end stamped to
shape.

Fig. 6, back view of same.
Fig. 7, a detachable blade.
Fig. 8, top end of shank, showing slot and recess.
Fig. 9, section of same through slot and recess.
Fig. 10, section, with blade in position.
We propose to punch out the blades to the desired form A, and to press the short
tang B, to a concave shape to fit into the concavity of the shank C, when the blade
is intended to be fixed permanently, as shown in Fig. 4.
The shanks and bow are cut out in one piece, the ends being of the configuration
shown in Fig. 1, and the various parts are afterwards bent and hollowed as shown
in Fig. 2. The extreme ends D, are doubled and pressed close as shown in Fig. 2,
one side being in line with the centre of the shank C, or thereabouts, against which
the flat side of the blade A, fits and is secured.
In the end of each shank C, we make a slit E, to admit the back of the blade,
the shoulder F, on the blade resting on the top of the shauk as seen in Fig. 6.
When the blade is placed in position it is secured by rivets or screws at G, and G.
In constructing a shear with removable blades, the blade A³, Fig. 7 is provided
with a recess H, at the back, and a deep notch I, in its extreme end, the end is not
concaved as before but is left flat.
The hole J, is screwthreaded as is the hole J², in the part D³, of the shank, or
they are otherwise prepared for a screw K.
back
At the back of the shank we cut out a slotted hole L, and
press
the metal so as to form a recess at M, the hole L, being to receive the part N, of
the tang of the blade, and the recess M, is to receive the point O, as shown
in Fig. 10, which shows the blade in position and secured ready for use by the
screw K.
The hole in the blade through which the screw K passes may be slotted, to
enable the blade to be removed without withdrawing the screw from the part.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim, is:
1. The improvements in sheep shears as herein before described and substantially
as shown.
2. In sheep shears constructing the shanks with the extreme ends pressed
together to form a tab D, and having a slit E, to receive the blade, as described
and shown.
3. In sheep shears having detachable blades provided with an end slot I, and
a recess H, the arrangement of a slotted hole L, and a recess M, for the purpose
specified.
