PROVISIONAL SPECIFICATION.
Improvements relating to Tools for Shearing or Clipping Hair
or Wool.
We, THE WOLSELEY SHEEP SHEARING MACHINE COMPANY LIMITED,
and HERBERT AUSTIN, both of Sydney Works, Broad Street, in the City of
Birmingham, Manufacturers, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the manner in which we construct the comb or bottom
plate of a sheep shearing machino and the top and bottom plate of a horse clipping
tool or like appliance, whereby the wool or hair is very readily cut or sheared, and
the keen cutting edges of the tool retained for a long period of service without
renewal.
In carrying our invention into effect we construct the cutters or plates in the
ordinary manner and cause the one to be reciprocated over the other by the action
of the tool or appliance to which it is attached. The comb or bottom plate has
teeth formed either at one or both edges as may be required. Instead of leaving
the upper sides or faces of the teeth at the same level or flush with the upper
surface of the body of the comb or bottom plate, we cut out the metal from
such upper faces of the teeth, or form a groove or depression between their
edges.
We preferably remove or cut out the metal by means of specially formed
milling tools or cutters, although we adopt other methods for effecting the same
purpose.
By thus arranging the edges of the comb teeth to stand above the surface
of the metal between them, we avoid the formation of ridges or projections
between such edges during the reciprocation of the top plate or cutter, and are
enabled to effectively employ the one comb for long periods of service without
renewal.
We do not limit the application of our invention to any particular type of hair
or wool shearing or clipping appliance, but adapt the same to hand tools, and to
the varying forms of machines employed for such purposes.
COMPLETE SPECIFICATIO
Improvements relating to Tools for Shearing or Clipping Hair
or Wool.
We, THE WOLSELEY SHEEP SHEARING MACHINE COMPANY LIMITED,
and HERBERT AUSTIN, both of Sydney Works, Broad Street, in the City of
Birmingham, Manufacturers, do hereby declare the nature of this invention and in

page_text: what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to the manner in which we construct the comb or bottom
plate or cutter of a sheep shearing machine, and the top and bottom plates or
cutters of a horse clipper or like appliance in order that the wool or hair shall be
very readily cut or sheared, and the keen cutting edges of the tools retained for
long periods of service without sharpening or renewal.
In order that our invention and the application of the same may be the more
readily understood we append hereunto two sheets of explanatory drawings to be
hereinafter referred to.
Figures 1 to 5 inclusive, on Sheet 1, illustrate the application of our invention
in connection with a sheep shearing machine.
Figure 1 is a part plan of the machine illustrating the comb or bottom plate or
cutter A in position beneath the top cutter B.
Figure 2 is a plan, and Figure 3 a sectional end elevation of the comb or bottom
plate or cutter A.
Figure 2 is a part plan showing a modified form of groove in the teeth of the
cutter A.
Figure 4 is a plan, and Figure 5 a sectional end elevation of the top plate or
cutter B.
Figures 6 to 8 inclusive, on Sheet 2, illustrate the application of our invention
in connection with a horse clipper or like appliance.
Figure 6 is a part plan of the clipper, showing the top and bottom plates or
cutters C and D in position.
Figure 7 is a part plan, and Figure 8 a sectional elevation representing to an
enlarged scale the form of the teeth or cutting edges of both the top and bottom
plates or cutters C and D.
Figure 7 is a part plan showing a modified form of groove in the teeth of the
cutters.
We produce the comb A of the sheep shearing machine, and the top and bottom
plates or cutters C and D of the horse clipping or like appliance, in the ordinary
manner, preferably from shear steel, providing teeth or cutting edges as illustrated.
We sometimes shape the comb and the top and bottom plates suitably for the
formation of teeth at each end of the same. We cause the one plate to be
reciprocated over the other by means of suitable mechanism forming part of the
shearing or clipping tool or appliance, and arranged for operation either by hand,
mechanical, or other power.
Instead of allowing the metal between the two cutting edges of each tooth to
remain flush or level with the upper surface of the comb A, or the top and bottom
plates C and D, as with the usual methods of construction we cut away such metal,
and thus form a groove or depression such as a in Figures 1, 2, 24, 3, 7, 7^, and 8.
We preferably remove or cut away the metal to form the grooves or depressions by
means of suitably shaped milling tools or cutters, although we adopt other methods
for effecting the same purpose.
By arranging that the cutting edges of the teeth shall stand above the surface of
the metal between them, as hereinbefore described, we avoid the formation of
ridges or projections between such edges during the reciprocation of the plates
when in service, and are thus enabled to effectively employ the comb such as A. or
the one pair of top and bottom plates C and D, for long periods of service without
sharpening or renewal.
We are aware that the top plate or cutter B of a sheep shearing machine "has
been previously made in a hollow form, as illustrated ou Sheet 1, and we make no
claim to such plates or cutters.
We do not limit the application of our invention to any particular type of hair
or wool shearing or clipping appliance, but adapt the same to hand tools, and to
the varying forms of machines employed for such purposes.

page_text: 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 improved construction of tools for shearing or clipping hair or wool con-
sisting in the removal of the metal between the cutting edges of the teeth
substantially as and for the purposes herein described.
