PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Driving Cutters for Clipping or
Shearing Horses or other Animals.
I, WILLIAM CLARK, of 528 Oxford Street, W. in the County of Middlesex,
Horse Clipper Manufacturer, do hereby declare the nature of this invention to be
as follows:-
My invention relates mainly to improvements in the apparatus for driving cutters
for clipping, or shearing horses, or other animals, for which Letters Patent were
granted to me as follows: No. 4099, bearing date March 18th 1887, and No. 4293,
bearing date, March 20th 1888.
The main objects of my present invention are to effect such improvements in the
construction of such driving apparatus as will simplify its construction and will
render the clippers or shears more easy of manipulation by the operator, while less
power will be required to drive the apparatus.
My improved machine is constructed substantially as follows: A hollow vertical
standard is affixed to a suitable base plate provided with means for attachment to
the ground. The said standard terminates at its upper end in a box or casing
containing a horizontal spindle provided at one end with a fly wheel and handle for
rotation by hand and at the other end with fast and loose wheels for diving by
power.
A spul wheel on the said spindle gears with a pinion on a second spindle, which
by means of bevel gearing drives a vertical shaft within a vertical tube or casing
extending above the said box.
A long light tube 18 jointed to the top of the said vertical tube in such manner
that it can be rotated around it horizontally and also moved through a vertical
angle from an upright to a horizontal position. It contains a light shaft driven
by bevel gearing from the aforesaid vertical shaft, and at its outer end has jointed
to it another and longer light tube, also containing a light shaft driven by bevel
gearing, of such construction, that the said gearing will transmit motion from one
shaft to the other, whether they are in line, or at an angle with each other.
To the end of this second light shaft, the chipping or sheating instrument 18
attached, through the medium of a flexible shaft, or bevel gearing, or a combination
of such flexible shaft and gearing.
To the top of the aforesaid vertical tube, a couple of long flat springs are
affixed, carrying at their outer ends a roller bearing on the under side of the tube
Jointed thereto.
These springs automatically raise the said tube into a vertical, or nearly vertical
position, and are so arranged and adjusted that the resistance they offer to the
pulling down of the tube, when the clipper is in use, is practically constant, thus
enabling the said chipper to be handled with great ease and facility in any
position.
No driving belts or cords are used in the machine, but the motion is imparted to
the clipping instrument from the first borizontal shaft entirely through the medium
of shafts and gearing, thus avoiding the loss of power in the clipper through the
shipping of such belts when too slack, or the absorption and waste of diving
power when they are too tight from the pressure on the various bearings.

Shearing Horses or other Animals.
I, WILLIAM CLARK, of 528 Oxford Street, W. in the County of Middlesex,
Horse Clipper Manufacturer, do hereby declare the unture of this invention and in
what manner the same is to bo peiformed, to be particularly described and
ascertained in and by the following statement :-
My invention relates mainly to improvements in the apparatus for driving
cutters for clipping, or shearing horses, or other animals, for which Letters Patent
were granted to ine as follows; No 4099, bearing date March 18, 1887 and
No. 4293, bearing date March 20th, 1888.
The main objects of my present invention are to effect such improvements in
the construction of such driving apparatus, as will simplify its manufacture, and
will give the operator more command over the clipping or shearing instrument, by
elieving the weight on the hand and causing the said strument to work more
steadily, rapidly and with less vibration, while less power will be required to drive
the apparatus.
In the accompanying four sheets of diawings, which form part of this
Specification, and in which similar letters of reference denote similar parts
throughout;
Fig. 118 a side elevation of an improved driving apparatus, constructed in
accordance with my present invention, the parts being in, or about the position
automatically assumed when the apparatus is at rest, and Fig 2 18 a similar view,
shewing the apparatus as extended when in use
Figs. 2 and 2 are detailed views of a modification,
Figs 3, 4, 5, 6, 7, 8 and 9 are detail views, to an enlarged scale, of various parts
of the mechanism, and
Figs 10, 11 and 12 are similar views, showing modifications of certain parts of
the said mechanism.
Referung first to Figs. 1 to 9, A is a base plate, provided with pierced lugs A¹
for attachment to a floor, or other foundation, by means of bolts, or other suitable
devices.
A vertical standard B, which may convemently be of a tubular form, as shown,
1 affixed to, or may be made in one piece with the said base plate
This standard has attached to it, at its upper end, a box or casing C. The said
box, with the attendant mechanisin, is shewn to an enlarged scale most clearly in
Fig. 3, which is a view at right angles to the position shewn in Figs. 1 and 2.
D is a horizontal spindle journalled in the box and provided at one end with a fly
wheel E and handle for rotation by hand, and at the other end with fast and
loose belt pulleys H, H', and belt fork J, for driving by power. A spur wheol K
18 keyed on this spindle D and gears with a pinion L, on a second houzoutal
spindle M, Jounalled in the upper part of the box C A bevel wheel N, also
fixed on the spindle M, gears with a bevel pinion P on the lower end of a vertical
shaft Q, journalled within a tube or shoath R, affixed to the top of the box C and
extending vertically above it.
Referring now more particularly to Figs. 4 and 5, which are elevations at right
angles to each other, to an enlarged scale, of the mechanism at the top of the
tube R, S 18 a sleeve encircling and free to rotate upon the said tube and beating
ou a collar T, but capable of being clamped in any required position by a thumb
screw V, provided for that put pose.
W, W, 18 a box, or casing, formed in two parts, the lower part W is fixed to
the top of, or made in one piece with the sleeve S. X is a horizontal spindle
Journalled in bearings W, projecting from the lower part W of the box, and the

page_text: upper part W of the box is also provided with projecting split bearings W³,
embracing the bearings W, 50 that the said puit W can ock through the
space Y.
A bovel pinion Z is fixed on the top of the shaft Q and gears with a bevel
wheel a on the spindle X. A long light tube is fixed to the top half W₁ of the
box, and bas joui nalled within it a light shaft c, having at its lower end a bevel
pinion d, gearing with the wheel a. By the combination of the rotating sleeve S,
the rocking box W, W, and the bevel gearing Z; a, d, the tube b can be moved
horizontally around the tube R and can assume various angles, as shewn in
Figs. 1 and 2, while in any position in which it can be placed, the contained shaft e
will be able to be driven with equal facility from the vertical shaft Q.
Jointed to and hanging from the upper end of the tube b, 18 a longer and lighter
tube having journalled within it a light shaft f. This shaft is driven from the
shaft e by a pair of suntably formed bevel gears g, g, see Figs. 8 and 9.
e
The form of gear which I preferably employ for this purpose, is, as shewn in the
said Figs. 8 and 9, a variable gear of the well-known construction, which will
transmit motion from one shaft to another, whether such shafts are in line, at an
angle, or parallel.
The tubes and e terminate in
containing the geats g, g The cup

cups g', 93, hu ged to each other at gỗ and
is fast on the tube e, but the cup g is loose
tube e to be moved into any position with
To the end of this shaft f, the clipping or shearing instrument, is attached, and
the said mstinment may be of any well known, or suitable construction, adapted to
the particular work required to be performed.
In order to obtain the necessary freedom of movement, in any direction, for the
said instrument, it is not affixed directly to the end of the shaft, but is connected
thereto by any suitable device, or devices which will provide the required
flexibility. Thus, for example, in Figs. 1 and 2, I shew a flexible shaft and a
pair of bevel or variable gears 1, 1, but I may use a flexible shaft alone, or one or
more pans of variable geais alone, or the ariangement of bevel gears descubed in
the Specification of my aforesaid Patent No. 4099 of 1887.
To the top of the aforesaid sleeve S, or lower part W of the box thereon, I affix
a couple of long flat spungs k, l, catiying at then outer ends a roller bearing
against the tube b. These springs automatically raise the said tube with its
dependent tube e, clipper and connections, into a vertical, or nearly vertical
position, as shewn in Fig. 1, and they are of such strength and proportions and Bo
adjusted, that the resistance they offer to the pulling down of the parts into the
position shewn in Fig 2, when the clipper is in use, is practically constant, for as
the tube approaches a horizontal position, the roller gradually approaches
neare to W, W, so that though the resistance of the springs to bending increases,
the leverage to overcome such resistance increases, while the pressme of the tube
on the roller necessarily increases as it approaches the horizontal position, and as
the sand spings aflord an excess counterbalance to the moving parts, only just
sufficient to raise them to the position shewn in Fig 1, the resistance to the hand
of the operator is very slight, and, as just explained, practically constant, so that
this arrangement, in combination with the freedom of movement of the tubes baud e
around and about the standard R, and of the tube e about the tube b enables the
clipping instrument to be handled and moved with great ease and certainty in
any position, or direction, while the weight is taken almost entirely off the hand.
The springs h, k, may be cased with rubber or leather mm, as shewn, to prevent
their chahng the tube b, and although in practice I prefer to employ a couple of
springs, a single spring may be used to serve the same purpose
In place of the Hat springs A, A, above described, springs A, A, Figs 24 and 28,
formed of round hand drawn steel wire, may be employed. Then lower ends are
secured lugs, and the wne is bent into a coil, thereby giving greater
clasticity and a large range of motion to the spring,

page_text: Figs. 10 and 11 represent two elevations, at right angles to each other, of a
modification of the paits shewn in Figs. 4 and 5, by means of which two clipping
or sheating instruments can be driven by the same apparatus.
In this case the spindle X and bearings W, W, on the lower part W of the box,
are extended in length and the upper part W of the box is in two parts W', W'
One pait has projecting bearings W³, W³, embracing the bearings W, w,
as before described with reference to Figs. 4 and 5, and the other part has
bearings W, W, carried by wings W, W, and embracing the extensions of the
bearings W, W.
Each part Wis provided with a tube b, carrying a shaft c, operated by a bevel
pinion d, from the besel wheel a, and each of these tubes and shafts has connected
to it a tube e and shaft f, with clipping instrument, as before described. Two
separate pans of springs h, k, are attached to the sleeve S, to counterbalance the
tubes and shafts, so that the two clipping instruments can be operated and moved
about, quite independently of each other
Fig. 12, represents in elevation, another mode of driving two instruments from
one apparatus Here the machine is the same as that shewn in Figs 1 to 9 as far
as the top of the tube . A lame u is fixed to the end of the said tube and caries.
a horizontal spindle p, diven from the shaft e by bevel gears q, r.
To each end of this shaft p, a tube e is attached by cups g', g, having bingos 9',
and containing shafts duiven by gears 9, 9, and during clipping insti Hinents.
The connections at the ends of the shaft p, are practically a duplication of the
arrangement shewn in Figs 8 and 9
No driving belts, cords, or chams, are used in the machine, but the motion 15
unparted to the clipping instrument, or instruments h, from the first motion shatt D,
entirely through the medium of shafts and genuing, so that a positive motion i8
imparted, without loss of power and speed, or risk of stoppage.
When belts or cords are employed in such a machine, if slack they slip, and
there is a loss of speed and power, and if tight enough to prevent slipping, they
are likely to break and absorb driving power to overcome the pressure thereby
caused on the bearings
These objections are entirely overcome in my improved machine.
In the machine thus illustrated and described, tho lower portion, included
between the base A and sleeve S is substantially the same as in the machine
described in the Specification of my aforesaid Letters Patent, No. 4293 of 1888,
and I therefore make no claim to such lower portion, but,
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be per formed, I declare that what I
claim, 18.—
