Improvements in the Construction of Sheep Shearing and Horse
Clipping Appliances.
°
We, THE WOLSELEY SHEEP SHEARING MACHINE COMPANY LIMITED and
HERBERT AUSTIN, both of Sydney Works, Broad Street, in the City of
Birmingham, Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to the manner in which we construct sheep shearing
and horse clipping appliances, the object of our invention being to make a clipper
or shearer which will have its cutting or clipping surfaces kept more truly in
contact and with less pressure upon the blades than is at present possible with the
ordinary existing methods of construction.
In carrying our invention into effect when constructing a horse clipper, we make
the comb with its teeth arranged in the usual well known manner and having a
handle for manipulating the same attached or carried upon it, and we mount above
it in any well known manner the clipping blade with its teeth formed to suit the
comb and having a handle for manipulating it connected to it in any ordinary
manner, thus making the usual well known appliance in which a pair of handles is
employed to give the reciprocating motion to the cutting surfaces of the comb and
cutter. We make the cutter of a peculiar shape so far as regards its bearing
surfaces which come in contact with the bottom or comb plate, the principles upon
which we construct the plate being to provide as far as possible bearing surfaces
having the nature of a triangular set or sets of points rather than a plain square
bed of contact between the moving surfaces. We make the back portion of the
blade when mounting it within a frame having two guiding and binding screws to
adjust the pressure between the surfaces, with a triangular shaped end on each
portion upon which the binding screws act so that the binding screw on cach side
will compress the cutter on to the comb surfaces, or vice versa, which having
somewhat the character of a triangular shaped bearing base, permits of the front
or cutting portion being more readily brought to a true bearing on the comb by
We
reason of the point like degree of contact of the other portion of the cutter.
make each portion of the cutting plate or shearing plate triangular in its back
bearing surface and we provide between the two triangles thus formed a bed or
contact slot for the end of the lever to work in for giving it the backward and
forward motion necessary for cutting. We shape the comb back surfaces also with
its corners removed so as to bring the same principle into play when the two
surfaces are clamped together by the binding screws. We thus relieve the meeting
or sliding surfaces of all superfluous metal and leave only sufficient and that
arranged in a peculiar manner for permitting of an easy and effectual clamp being
obtained without setting too great a pressure to cause friction between the two
sliding plates. We modify the shape and configuration of our plates to suit the
character or class of clipper which is to be employed, in each instance however
inaking the bearing surfaces between the plates as far as possible triangular in
the manner in which the thrust is received from the binding and clamping screws.
We employ the ordinary mountings and other usual fittings in connection with the
clippers, our present invention only having reference to the manner in which the
blades are brought to bear upon each other.

Clipping Appliances.
We, THE WOLSELEY SHEEP SHEARING MACHINE COMPANY LIMITED and
HERBERT AUSTIN, both of Sydney Works, Broad Street, in the City of
Birmingham, Engineers, 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 has reference to the manner in which we construct sheep shearing
and horse clipping appliances, the object of our invention being to make a clipper
or shearer which will have its cutting or clipping surfaces kept more truly in
contact and with less pressure upon the blades thau is at present possible with the
ordinary existing methods of construction.
In the accompanying sheet of explanatory drawings,
Figure 1 is a plan of our improved clipper.
Figure 2 is a detailed plan of the blade, and Figure 3 is a sectional elevation of
the same.
Figure 4 is a detailed plan of the comb and Figure 5 is a sectional elevation of
the same.
Figure 6 and Figure 7 are detail views of the spring washer plate.
In carrying our invention into effect when constructing a horse clipper as shown
in Figure 1, we make the comb A with its teeth a arranged in the usual well known
manner and having a handle C for manipulating the same attached or carried
upon it, and we mount above it in any well known manner the clipping blade B
with its teeth formed to suit the comb and having a handle C' for manipulating
it connected to it in any ordinary manner, thus making the usual well known
appliance in which a pair of handles C C¹ is employed to give the reciprocating
motion to the cutting surfaces of the comb and cutter. We make the cutter B of
a peculiar shape so far as regards its bearing surfaces which come in contact with.
the bottom or comb plate A, the principle upon which we construct the plate being
to provide as far as possible bearing surfaces having the nature of a triangular set
or sets of points 6' 63 63 rather than a plain square bed of contact between the
moving surfaces. We make the back portion of the blade B (when mounting it
within a frame having two guiding and binding screws to adjust the pressure
between the surfaces), with a triangular shaped end 616263 on each portion upon
which the binding screws D act so that the binding screw on each side will compress
the cutter B on to the comb surfaces A, or vice versa, which having somewhat the
character of a triangular shaped bearing base, permits of the front or cutting
portion being more readily brought to a true bearing on the comb by reason
of the point like degree of contact of the other portion of the cutter 66.
make each portion of the cutting plate or shearing plate approximately triangular
in its back bearing surface and we provide between the two triangles thus
formed a bed or contact slot for the end of the lever to work in for giving it
the backward and forward motion necessary for cutting. We shape the comb back
surfaces also with its corners a¹ a² shown in dotted lines in Figure 4 removed, so as
to bring the same principle of triangulation of bearing into play when the two
surfaces are clamped together by the binding screws D. We thus relieve the
meeting or sliding surfaces of all superfluous metal and leave only sufficient metal
which we arrange in a peculiar manner for permitting of an easy and effectual
clamp being obtained without setting too.great a pressure to cause friction between
the two sliding plates. We modify the shape and configuration of our plates to
suit the character or class of clipper which is to be employed, in each instance
however making the cutting bearing surfaces to be arranged as far as possible

and clamping screws. We employ the ordinary mountings and other usual
fittings EF in connection with the clippers, our present invention only having
reference to the manner in which the blades are formed so as to enable the cutting
faces to be brought into close contact with as little pressure as possible.
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 :-
The construction of cutter blades and combs for shearing and clipping appliances
in which the bearing surfaces are relieved by being formed into triangularly
arranged points in the same plane of contact substantially as and for the purposes
hereinbefore described and as illustrated in the accompanying drawings..
