Improvements in Machinery for Imparting Motion to Flexible
Shafting for Driving Sheep-shearing and Clipping Apparatus
and for other Purposes.
·
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 to be as follows:-
My invention relates mainly to frictional machinery or apparatus which is especially
applicable for transmitting motion to flexible shafts for driving sheep-shearing and
clipping apparatus but which is also applicable for other purposes.
According to my invention I provide a projecting arm or bracket which at its rear
end is carried in a socket adapted to be screwed to a wall or post, the said arın being
mounted in the socket in such a manner that it can be adjusted therein in either
a vertical or lateral direction. Upon the said arm is mounted a plummer block
which is adapted to be adjusted on the arm by means of set screws, and which
serves to support the shaft through the medium of which motion is imparted to the
apparatus. To the underside of the said plummer block is hinged an arm or bracket
carrying a spindle, one end of which is provided with a spring bayonet fastening
for connection to the flexible shaft, through the medium of which the motion of the
apparatus can be communicated to the shearing or clipping apparatus to be operated;
while upon the other end of the spindle is a friction pinion, designed to engage with a
corresponding friction wheel secured to the shaft working in the plummer block.
The arm carrying the friction pinion is pivoted to the plummer block, so that the
pinion can be thrown out of contact with the friction wheel, and a spring is pro-
vided for pressing the said arm and consequently also the friction pinion against the
friction wheel.
In connection with the said arm or bracket is also arranged a double ended lever,
to which cords can be attached for operating the same.
.
By. moving this lever in one or the other direction, as desired, the lever arm can
be moved to place the friction pinion in or out of contact with the friction wheel.

COMPLETE SPECIFICATION.
Improvements in Machinery for Imparting Motion to: Flexible
Shafting for Driving Sheep-shearing and Clipping Apparatus
and for other Purposes.
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 frictional machinery or apparatus which is especially
applicable for transmitting motion to flexible shafting for driving sheep-shearing and
clipping apparatus but which is also applicable for other purposes.
In the accompanying drawings,
Figure 1 is a side elevation of my improved machinery or apparatus; and

page_text: Ingates
decans, meremarter described.
Figure 10 is a perspective view illustrating the application of my improved
apparatus for shearing sheep.
a is the main-driving shaft of the apparatus, 6 is a bevel friction wheel supported
thereon, and c is a bevel friction pinion through which the motion of the wheel b is
communicated to the flexible or other shaft to be driven. d is a plummer block in
which the shaft a is journalled, the said plummer block being mounted upon an
arm or bracket e projecting from a wall or post, and secured thereon by means of
set-screws e¹.
and
The said arm or bracket is adapted to be adjusted both laterally and vertically to
enable the said plummer block to be accurately placed relatively to the shaft α,
for this purpose, the said arm or bracket e (which is shown detached in elevation and
plan in figures 3 and 4 respectively) is provided at its rear end with a supporting
piece fand carried in a socket g (shown detached in elevation and horizontal section
in figures 5 and 6 respectively) designed to be fixed to a wall, or to a post, as shown
in figure 10. The said arme is introduced into the socket from the back before
the latter is fixed, so that the supporting piece frests therein, as shown in dotted
lines in figure 2. The arm itself projects through a slot h formed in the front of the
said socket, the said slot being made somewhat wider and longer than is absolutely
necessary to allow for the movement of the said arm to one side or the other as may
be required. The vertical adjustment of the arm is effected by means of a set-screw i
in the underside of the said socket g, as shown in figures 1 and 2. The supporting
piece is provided with two studs k, k, also projecting through the slot h, which
studs carry nuts 1, 1 and washers m, m, the latter of which are curved on one face to
approximate to the shape of the said socket g. When the said nuts are tightened
the arm will be firmly held in any position in which it may be adjusted.
This
The friction pinion c is mounted on a spindle n carried in a bracket o.
bracket is pivotted to the underside of the plummer block d at p in such a manner
that the normal tendency of the said bracket, owing to its weight and assisted by
the action of a spring 9 is to remain..in such a position that the said friction pinion.c
will be out of contact with the friction wheel b. In order to press the said pinion c
against the wheel b, when it is required to communicate the motion of the latter to
the former, I provide a spring r adapted to be moved to press against the rear side
of the bracket o, as shown in figures 1 and 2. For this purpose the said spring r
is pivottally connected at its upper end to the plummer block d, as shown at s, and
at its lower end is provided with a pint projecting through a slot u in the arm of
a lever u¹ pivotted at u³ to the bracket o. The said lever u¹ is provided at its opposite
ends with cords or rods v, vl by means of which it can be operated. With this
construction, it will be obvious, by reference to figure 2 that, if the cord v³ is pulled
so as to move the lever u¹ the spring will also be moved from the position indicated
in dotted lines in figure 2, where it is out of contact with the bracket o into the
position indicated in full lines, whereby the said bracket will be operated to press
the pinion c against the wheel b, where it will be held with a yielding pressure.
When the cord v is pulled the spring will return to the position indicated in dotted
lines in figure 2, thereby moving the pinion c out of contact with the wheel b.
་
On the spring is formed a lug or projection w adapted to enter a corresponding
recess in the bracket o to prevent the accidental movement of the said spring by
reason of any vibration to which the apparatus may be subjected.
:
The end w¹ of the bottom of the bracket is bevelled, as shown in figure 7 which is
a section on the line xx figure 2, so as to offer no obstruction to the movement of
the spring r.
The lower end of the spindle n on which the friction pinion c is mounted, is
preferably formed as one part y of a bayonet joint, as shown most clearly in figure 8
(which is a view of the said end drawn to an enlarged scale); the other part 2 of the
said joint, which is designed for attachment to a flexible or other shaft, being shown
in figure 9. 22 is a slot formed in the part z adapted to receive a pin yl on the
party, which part y is also provided with a spring y² adapted when the part z

page_text: is applied to the part y and turned to enter the slot z' to lock the parts in
position.
It is to be understood that any suitable arrangement may be used in lieu of that
described for connecting the flexible or other shaft to the spindle n.
Having now particularly described and ascertained 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. In machinery or apparatus for imparting motion to shafting for driving sheep-
shearing and clipping apparatus and for other purposes, mounting the plummer block,
in which the main driving shaft is journalled, upon an arm or bracket adapted
to be adjusted both laterally and vertically, substantially as, and for the purposes,
described.
2. The combination with a plummer block mounted in the manner described, of
a bracket pivotted thereto and carrying a friction pinion and spindle in such a
manner that by moving the said bracket in one or the other direction upon its pivot,
the said pinion can be moved into or out of contact with a friction wheel on the
main driving shaft, substantially as described.
3. The combination with the plummer block having the bracket pivotted thereto
as described, of a spring adapted to bear against the said bracket to force the pinion
thereon into contact with the driving wheel and to be moved out of contact with the
said bracket, substantially as, and for the purpose, described.
4. The manufacture and use of the improved apparatus herein before described
and illustrated in the accompanying drawings.
