Improvements in Apparatus for Driving Shears or Cutters for
Clipping Horses or other Animals.
WILLIAM CLARK 528 Oxford Street W. London, Horse Clipper Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The object of my Invention is the construction of an Apparatus to be employed for
driving Cutters or Shears, for clipping the hair of Horses, or shearing the wool from
sheep or other animals, or for other similar or like purposes, and the Improvements
consist in providing a frame or standard supporting a driving wheel and pulley, the
said pulley through the medium of a cord, drives a small pulley on an axle giving
motion to a pair of bevil wheels, one of which drives a shaft shielded by a tube.
To the bottom of the rod carrying the small driving pullies a weight is connected
in a manner which will allow the said rod to move freely in a circle round the driving
shaft centre in any direction. The shaft inside the tube driven by the aforesaid bevil
wheels, gives motion to a pair of mitre wheels, at the bottom end of such shaft, one of
the mitre wheels is connected by a short spindle with a second pair of mitre wheels
giving motion to the spindle in the handle of the clipper driving the cutters.
The said pair of mitres are capable of turning in any direction to suit the position
of the hand of the operator so that the greatest freedom of action may be secured and
the said pair of mitres may be placed either in the rear of the handle or in front
thereof.
I would further remark that 1 prefer to use in connection with this class of Improved
driver, spring fingers for giving a yielding pressure to the cutter plate of the instrument
such as that described in the Specification and patented by me on the 3rd day of
February 1877 and numbered, 459, the combination of which with such driving
Apparatus will not only maintain the cutters in perfect yielding contact, but will with
the driving gear enable the whole apparatus to be worked with the greatest freedom
in what ever position the clipper may be placed whilst in operation.

I WILLIAM CLARK of 528 Oxford Street, in the County of Middlesex Horse Clippper
Manufacturer, 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 the construction of an Apparatus to be employed for
driving cutters or Shears for clipping the hair of Horses or shearing the wool from
Sheep or other animals, or for other similar or like purposes, and the Improvements
consist in connecting the prime mover by an arrangement of mitre wheels with the
cutting instrument in such a manner that during the time the cutters are being driven
the instrument or shears can be traversed by the operator with the greatest ease
over the surface of the Animal which requires the hair or wool to be cut or sheared
therefrom.
In order that the Invention may be well understood and explained in detail I have
hereunto annexed two sheets of Drawings on which letters of reference are marked
on corresponding parts on all the Figs. alike.
DESCRIPTION OF DRAWINGS.
Fig. 1. represents a front elevation of the shearing instrument shewing the method
of communicating motion in any position to the cutter from the prime mover through
the medium of mitre wheels, (the casing of which is shewn in section) placed at the
rear end of the handle by which the instrument is taken hold of.
Fig. 2 represents a side elevation of the same.
Fig. 3 represents a similar view to that shewn at Fig. 1. in which the mitre wheels
transmitting motion to the cutters are placed in front of the handle.
Fig. 4 represents a side elevation of the same, in both of these Figs. (3 and 4) the
outer casing or shield for the mitre wheels is shewn in dotted lines, and
Fig. 5 represents an arrangement of driving apparatus which transmits motion to
the mitre wheels driving the cutters of the shearing instrument.
In these Figs. a is the upright or standard supporting the driving wheel on the
axle of which is supported the balanced vibrating rod c provided at its top end with
the pulley d and bevil gearing e which through the medium of the cord a' communi-
cates motion to the rod fenclosed in the swinging or vibrating tube f¹ the whole of
such driving apparatus being well known.
The bottom end of the rod is provided with a screw and coupling nut 9 and is
so shaped that when the screw h forming the axle of the first pair of mitre wheels /
is fitted thereto, the said screws and h are coupled together by the nut g and so form
a direct connection with the bevil gearing e driven by the cord a' from the main
driver. The series of mitre wheels h and i, with their axles are so arranged and
closed in by the casing that when so coupled up to the main driver they will

page_text: communicate motion to the cutters of the instrument A in whatever direction such
instrument may be placed (when at work) relative to the position assumed by the
rod f of the driving apparatus. The arrangement for transmitting motion to the
cutter through the medium of such mitre wheels placed at the rear of the handle
shewn at Figs. 1. and 2 is by the spindle and disc m the crank pin of which enters a
ball placed in the tube n of the lever o connected with the cutter, thus when the
apparatus is at work, the rapid motion given to the disc m causes its crank pin to
transmit a rapid to and fro motion to the cutters through the medium of the lever o
and so enables the hair or wool to be cut or sheared from the animal under operation
with the greatest ease no matter what position the shearing instrument has to assume
relative to the surface of the animal on which it is operating.
The action of the shears shewn at Figs. 3 and 4 is exactly similar when coupled up
with the driving apparatus, the only exception in this instance is that the motion is
communicated through the medium of the mitre wheels and crank disc direct to the
cutters in front of the handle, the shielding case in these views is shewn by
dotted lines.
It will be evident that a number of such instruments may be so arranged that they
can be operated by one main driver, in this case each shearing instrument with
its universal driving gear will be connected to the main driver by means of friction
clutches or their equivalent.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare that what I claim is :-
:-
In apparatus for driving that description of Instrument known as a "Clipper" for
shearing hair or wool from Horses, Sheep or other animals, of the universal mitre
gearing marked h¹, i and in the drawings so connected to the rear or front of the
handle of such instrument, that they will when motion is communicated to them
transmit a rapid rotation to a crank disc m giving motion to the lever driving the
cutters in whatever position such cutters may be relative to the main driver, substantially
as described herein, and shewn in the drawings annexed.
