Improvements in Sheep Shears.
We CHARLES BURGON of Malin Bridge Sheffield in the County. of York Sheep
Shear Manufacturer, and THOMAS OAKLEY of Dykes Hall Road Hillsborough
Sheffield Sheep Shear Manager do hereby declare the nature of this invention to be as
follows:-
The object of this Invention is, the making of sheep shears so that each or either
blade can be very readily and most accurately interchangeable, that is, when it is
required to change one blade of the shears for another, any shear blade. made
according to these improvements will most accurately fit into or with the other blade
in or at the double bow of the shears, an object which has not hitherto been attained
with certainty and success.
Our Invention consists principally in making the tongue of each half of the double
bow of a pair of sheep shears with two holes therein, one hole being made larger than
the other; a stud or plate is provided to be used therewith, having a screwed pin and
a plain or other pin fixed or made on or in it; the screwed pin is passed through
the larger hole in each tongue of the double bow, and the other pin through the
smaller hole in each tongue, the whole is then fastened together by means of a washer
and a thumb screw, put and operated on the screwed pin, and the whole is tightened
up as required; or other suitable fastening or tightening up means can be used,
if necessary, so long as the same are equally applicable to either half of the double
bow of the shears.
Or instead of employing the above described means of making the shear blades
interchangeable we can attain the same result by providing suitable sliding studs and
screws or pins in or connected with the tongue of each bow of the shear.

COMPLETE SPECIFICATION.
Improvements in Sheep Shears.
We CHARLES BURGON of Malin Bridge Sheffield in the County of York Sheep
Shear. Manufacturer and THOMAS OAKLEY of Dykes Hall Road Hillsborough Sheffield
Sheep Shear Manager do hereby declare the nature of this invention and in what
marner the same is to be performed, to be particularly described and ascertained
in and by the following statement in writing, and on reference to the accompanying
sheet of drawings:
:-
The object of this Invention is the making of sheep shears so that each or either
blade can be very readily and most accurately interchanged or interchangeable for
sharpening, grinding, whetting, and other purposes such as for replacing a damaged
or an unevenly tempered blade, or when it is required to change one blade of the
shears for another, any shear blade made according to these improvements will
most accurately fit into or with the other blade in or at the double bow of the shears,
an object which has not hitherto been attained with certainty and success.
In order that our said invention and the manner of carrying it into practical
effect may be fully understood it is illustrated on the accompanying sheet of explana-
tory drawings, which sheet is marked with figures and letters of reference corre-
sponding with those in the following description thereof, that is to say :-
Figure 1, represents a pair of sheep shears, constructed as we prefer to make the
same, and embodying the principal features of our improvements.

page_text: Figure 2, shows views (drawn about full size) of the tongue portions of the double
bow of our improved sheep shears.
Figures 3 to 5 inclusive show details of the separate parts of our fastening and
tightening up appliances.
Figure 6, shows views (about full size) of the tongue portions made according to
the modified form of our improvements.
And, Figures 7 to 10 inclusive show details of the separate parts constituting the
inodified form of our fastening and tightening up appliances.
Our invention consists principally in making the tongue a, of each half of the
double bow of a pair of sheep shears with two holes b, c, therein, one hole b, being
made larger than the other onc c, as seen at Figure 2. A stud or plate d,
(shown at Figures 3 and 4) is provided for use therewith having a screwed pin e,
and a plain or other pin f, fixed or made on or in it (see Figure 3) the screwed
pin e, is passed through the larger hole b, in each tongue of the double bow, and
the other pin f, through the smaller hole e, in each tongue; the whole is then fastened
together by means of a thumbscrew g (Figures 1, and 5,) which is fitted to and
operated on the screwed pin e, and the whole is tightened up as required, a washer
being used therewith, or not as found necessary.
Or, any other suitable fastening or tightening up means can be used if necessary
or desired, so long as such fastening or tightening up is equally applicable to either
half of the double bow of the shears.
According to a modification of this invention, instead of employing the above
described means of making the shear blades interchangeable we attain the same
result by cutting or slotting the tongue a, of each half of the double bow of the
shears as shown at h, in Figure 6, and we apply thereto a sliding stud i, as
shown at Figures 8, and 9, on which stud is a screwed pin j; the whole is fastened
together by means of a thumb screw k, being fitted and operated on the screwed
pinj. As shown in Figures 7, and 8, a part 1, of the top of the stud i, is made-
loose so as to make the fastening or tightening up more effective.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The making of improved sheep shears in such a manner that either or both
of the blades will be easily and accurately interchangeable when required for
another blade or other blades made according to this invention, such other blade
or blades accurately fitting into the double how of the shears; substantially as
herein before described and as illustrated on the accompanying sheet of drawings.
2. The hereinbefore described improved means of fastening together the double
bows of sheep shears and tightening up the same by providing and using the
appliances as shown either at Figures 3, to 5, or at Figures 7, to 10, inclusive,
on the accompanying explanatory drawings, or any modification or variation in the
construction of the same.
