We, WILLIAM WALTER BARTON and ARTHUR THOMAS BARTON, both of 103, New
Oxford Street, London, W., Horse Clipping and Sheep Shearing Machine Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to produce a simple, convenient, and effective
machine for clipping horses and shearing sheep.
A machine which is suitable for clipping horses is not at all suitable for shearing
sheep, the power required for the latter purpose being much greater, for several
reasons, than is necessary in the former case. At the same time, a sheep-shearing
machine does not lend itself conveniently for clipping horses, and as in many
places, both the operations of clipping horses and shearing sheep are carried on,
the production of a suitable and economical machine for effecting both operations
will supply a long-felt want, which many attempts have been made to fill without
success.
Several years' experience in the sale of horse-clipping machines has shewn to us
where the difficulties lie, and applications for a machine which will shear sheep
as well as clip horses, have demonstrated to us the need for such a machine.
In carrying out our invention, we make use of pedal power for the purpose of
driving the machine, a power which has proved hitherto ample for the clipping of
horses, and this power is applied in different ways for the two purposes in view.
To a base of cast metal are fitted two standards or posts, one post carrying the
pedal power mechanism, and the other a seat for the attendant who is to drive the
machine. These two posts are connected together at top by a stay or strut, which,
with the solid base and the posts, form a kind of rigid frame for the power
mechanism.
Extending forward horizontally from the post, is a bar or tube, which serves the
double purpose of a spacing bar and a steadying bar.
Two standards or posts carry a shaft, and at the centre of this shaft is mounted
a bridge piece, having a stem which fits into the tube, and is secured therein by
a clamping screw, or in any other convenient manner.
Under the bridge, and upon the shaft, is mounted a pulley, which receives a
band or cord from the pedal mechanism.
Mounted upon the shaft is a sheep-shearing mechanism, which consists of a
counter-weighted bar secured to a sleeve mounted loosely on the shaft.
At the outer end of this bar, is fitted a flexible shaft, which is driven by a cord
or chain from a pulley or chain wheel on the shaft.
It being necessary, in order to get good results, to drive the shearing knife at
a high rate of speed, the diameters of various pulleys or wheels required will be
so regulated as to cause the shaft to attain a high speed without any increase
of the pedal power.
When it is desired to clip horses, the sheep shearing mechanism is unshipped

page_text: and taken away, and a driving band or cord from the pedal mechanism is adapted
to a pulley of the horse-clipping mechanism, which is carried by the frame, and
extends upwards in a diagonal direction from the post.

We, WILLIAM WALTER BARTON and ARTHUR THOMAS BARTON, both of 103, New.
Oxford Street, London, W., Horse Clipping and Sheep Shearing Machine Manu-
facturers, 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:-
The object of this invention is to produce a simple, convenient, and effective
combined machine for clipping horses and shearing sheep.
A machine which is suitable for clipping horses is not at all suitable for shearing
sheep, the power required for the latter purpose being much greater, for several
reasons, than is necessary in the former case. At the same time, a sheep-shearing
machine does not lend itself conveniently for clipping horses, and as in many
places both the operations of clipping horses and shearing sheep are carried on,
the production of a suitable and economical machine for effecting both operations
will supply a long felt want which many attempts have been made to fill without
success.
Several years' experience in the sale of horse clipping machines has shewn to us
where the difficulties lie and applications for a machine which will shear sheep
as well as clip horses have demonstrated to us the need for such a machine.
In carrying out our invention we make use of pedal power for the purpose of
driving the machine a power which has proved hitherto ample for the clipping of
horses and this power is applied in different ways for the two purposes in view.
In the accompanying drawings---

shearing sheep and
Fig. 2 is a front elevation of the same.
is a base of cast metal into which are fitted two standards be one standard b
carrying the pedal mechanism and the other ca seat for the attendant who is to
drive the machine. These two standards are connected together at top by a stay
or strut which with the solid base and the standards form a kind of rigid frame
for the power mechanism.
and
The standard which is preferably forked at its lower end has bearings e for the
pedal action f on which is mounted in the fork of the standard a fly wheel
at either end a pedal crank to which the pedals i are fitted in the usual way.
Above the wheel g and extending forward horizontally from the standard is
a bar or tube j which serves the double purpose of a spacing bar and a steadying
bar.
kare two standards which at their upper ends support forked bearings / for
a shaft m. At the centre of this shaft m is mounted a bridge piece n having a
stem which fits into the tube and is secured therein by a clamping screw or
in any other convenient manner. Between the bearings and the bridge piece n
are sleeves which connects these parts together and form a rigid support for
the shaft m.

page_text: Under the bridge piece and upon the shaft m is mounted a pulley p which is
driven by a band or cord g from the fly wheel g.
This band or cord is tightened up by shifting the shaft m and its accessories
outwards and then clamping the stem o to the tube in the new position.
Between each bearing and upon the shaft m is carried a counter-weighted bar r
secured to a sockets mounted loosely on the shaft m.
At the outer end of this bar r is a forked bearing for level gearing mechanism
for driving a flexible shaft which gearing is of the usual construction and with
the shaft and a cutter (not shown) constitutes the shearing mechanism. This
mechanism is driven by means of a small pulley u round which passes a cord from
the larger pulleye on the shaft m.
It being necessary in order to get good results to drive the shearing knife at
a high rate of speed the diameters of these various pulleys or wheels pu and
will be so regulated as to cause the pulley to attain such high speed without
necessitating any increase of the pedal power and thus a great amount of work
will result from the expenditure of comparatively little power.
By mounting the sheep-shearing mechanisms loosely on the shaft m and pro-
viding the counterweight on the bar any slack in the flexible shaft will be at
once taken up and no undue strain on the hand and arm of the attendent who is
directing the shearing knife will be caused when he desires to lengthen the space
over which the machine will be operative by pulling down the bar r.
When it is desired to clip horses the sheep-shearing mechanisms may be un-
shipped and taken away and the driving band or cord from the wheel is adapted
to the pulley arranged on a shaft between two horse-clipping mechanisms.
These mechanisms are of the usual character, that is to say the knives are
attached to flexible shafts operated by bevel gearing and need no further descrip-
tion. They are carried by the frame which extends upwards in a diagonal
direction from the post band is rigid, the mechanisms having stems or pieces
which enter the tubes of the frame and are clamped therein in any convenient
manner. Thus the horse-clipping mechanisms may be unshipped and taken away
when desired.
y is a handle bar attached to the standard b for the attendent to hold on to
while driving and z is a step attached to the standard e to enable the attendant to
mount to his seat or saddle both of which are usual in this class of machine.
It may be here remarked that the flexible shafts, the bevel gearing employed
to operate them and the knives which constitute the clipping and shearing
mechanism, form no part of the present invention as these parts are now well
known. The running and moving parts will also be provided with any suitable
means for overcoming friction.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. A combined machine suitable for clipping horses and shearing sheep and
consisting of a main frame containing a pedal-propelled driving wheel and a seat
for the attendant, a frame extending forwards from the main frame in an upward
direction and carrying horse clipping mechanisms driven from the pedal wheel,
a separate shaft carried by standards connected to the main frame by a spacing
bar or tube, the said shaft being provided with pulleys and driven from the pedal
wheel, sheep-shearing mechanisms carried by counterweighted bars or rods
mounted loosely on the shaft and driven by wheels or pulleys so regulated in size
as to give a high speed to the shearing mechanisms without increasing the pedal
speed all as herein shown and described.
2. In a combined horse clipping and sheep shearing machine operated by pedal
driving mechanism duplicate sheep shearing mechanisms carried by counter-
weighted rods mounted loosely on a shaft the said shaft being mounted in sleeves
with a saddle piece and forked bearings carried by standards and driven from the

page_text: pedal mechanism the rotary motion of the shaft being communicated to the
shearing mechanisms by cords and pulleys all as set forth.
3. A combined horse clipping and sheep shearing machine constructed arranged
and operating as herein shown and described with reference to the drawings.
