COMPLETE SPECIFICATION.
Improvements in Cutters and Combs for Sheep-shears, Horse-
clippers and similar Instruments, and in Holders therefor.
I, FREDERICK YORK WOLSELEY, of the Union Club, Sydney, in the Colony of New
South Wales, and the Oriental Club, Hanover Square, in the County of London,
Gentleman, 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 :-
My invention relates to cutters and combs for sheep-shears, horse-clippers and
similar instruments, and has for its object to facilitate the grinding, setting or
sharpening of the same.
Hitherto considerable difficulty has been experienced in grinding, setting or
sharpening the cutters and combs of sheep-shears, horse-clippers and like instru-
ments in consequence of the difficulty of holding them against the setting or
grinding disc.
According to my invention I form, in each cutter or comb, holes or recesses, as
hereinafter described, and 1 provide a holder having two spring legs or arms
adapted to take into the holes or recesses in the cutter or comb, whereby the latter
will be firmly clipped.
To enable my invention to be fully understood I will describe the same with reference
to the accompanying drawing, in which
Figure 1 is a side elevation of a holder, constructed according to my inven-
tion; and
Figure 2 is a plan of the same.
Figures 3 and 4 are a plan, and edge view respectively of a comb provided with
holes according to my invention so as to adapt it to be held by the holder.
Figures 5, 6 and 7 are a plan, edge view and section respectively of a part of a
comb provided with recesses according to my invention.
I will first describe the holder, a being the handle which is recessod or slotted
at b, and c a socket pivotted in the slot b by the pin d, so that the handle can
be moved relatively to the said socket, for instance, as indicated by the dotted lines e,
figure 2. f is a projection on the socket entering a recess g in the handle to limit
the movement of the latter.
h, h are spring legs or arms which, as shown, can be advantageously formed out of
a single piece of steel, held by lugs or clips i, i in the socket, and bent so that their
free ends j, j pass through and project beyond the end of the socket, the normal
tendency of the said arms being to spring apart.
The
In order to enable the combs or cutters to be held by the holder bereinbefore
described I provide each of them with two holes or apertures k, k for instance, as
shown in Figures 3 and 4, to receive the projecting ends j, j of the arms.
holes k, k are placed at such a distance apart that in order to introduce the ends of
the arms it is necessary to spring the same towards each other.
tendency of the arms to spring outwards causes the clipping of the comb so as to
prevent it from slipping off the holder.
The natural
It will be noticed that the outer end of the socket c is of a curved or rounded form,
and that the ends j, j of the arms h, h are smaller than the holes k, k. This arrange-
ment enables the holder to be moved relatively to the comb or cutter being ground or
set, for instance as indicated by the dotted lines in Figure 1.
This freedom of
motion, together with that of the handle a relatively to the socket, permits of an
even pressure being put upon the comb or cutter, while being ground, set or
sharpened.
Instead of forming holes k, k in the cutter or comb, I can in some cases, when the
thickness of the comb or cutter will allow of it, form recesses in the edge, for instance

page_text: as shewn in Figures 5, 6 and 7 where indicates a V-shaped recess, one of which is
formed in each side of the comb. In this case, however, it will be obviously necessary
to arrange the arms to spring towards each other, and to form the ends j, j with
lateral projections adapted to enter the recesses I, I so as to clip the comb or cutter to
be operated upon.
Instead of employing spring legs as hereinbefore described it will be obvious that
the legs may be operated by a screw but I do not advise this arrangement.
Having now particularly described and explained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1.) Combs or cutters for sheep-shears, horse-clippers and similar instruments
formed with holes or recesses adapted to receive the ends of spring legs, or legs
operated by a screw, substantially in the manner, and for the purpose, set forth.
(2.) An apparatus for holding the cutters or combs of sheep-shears, horse-clippers
and similar instruments while they are being ground, set or sharpened, having spring
legs, or legs operated by a screw, adapted to enter holes or recesses and clip such
cutters or combs, substantially as hereinbefore described.
(3.) The improved holder constructed substantially as herein before described and
illustrated in the accompanying drawing for the purpose specified.
