is an adjustable collar screwed to the pillar as shown, provided for the pur-
pose of forming a connection which will not work loose by reason of vibration.
The upper face of this collar is cupped to correspond to a raised cone shaped
ring or ixed washer surrounding the aperture E' in the upper section of body E
(Figure 6) through which the pillar passes, so that when the nut C³ (Figure 1)
is screwed tight the raised, ring or washer E7 18 securely imbedded in the cupped
recess of the collar C thus forming a rigid and locked joint

Figure 5 is plan showing lower section of body C, and lower blade A with
oscillating plate D carrying upper plate B, all in position
As will be seen in this drawing the points of the lower blade A project beyond
those of the upper blade B and thus prevent the oscillating blade from coming
into cutting contact with the pelt of the sheep, by this means the need for a
comb 18 obviated
The spring C is provided for the purpose of facilitating the removal and re-
placing of the blade B, by holding the oscillating plate D in position.
The other parts shown have been previously described

page_text: L³ Ls are the apertures through which the spindle K passes, on which the
reciprocating lever oscillates.
The transmitting thumb L' consists of a detachable angle piece the upper
portion of which fits into a recess in one end of the lever as shown, and is secured
therein by means of pivot L' The recess is so constructed as to allow the
thumb La certain amount of play to enable it to accommodate itself to the
differences in radius between the reciprocating lever and the oscillating plate, a
small spiral spring L being provided for the purpose of retaining the thumb L'
in its normal position
Figures 9, 10, 11, 12, 13, 14, shew the separate parts of the tension appliance
shown in position in Figure 6 and 7 to which I now revert in conjunction there-
with
FI (Figures 9 and 6) is a bent shaft to which 18 pivotted a tension block F
which is retained in its normal position by a spring F.
At one end of the shaft F at right angles thereto, a bracket carrying a pair of
Jaws F F 18 constructed Between these jaws, the tension screw (the parts of
which are shown in Figures 12, 13) is secured by a pin F6 as shown in Figure 6.
This pin passes through the aperture lettered F in the different parts.
(Figures 12 & 13) In Figures 10 and 11, and F are the bearings supporting
the ends of tension shaft F shown in position in Figure 6
The tension screw
18 constructed in two parts as shown in Figures 12 and 13 which are held to-
gether by the pin Fe (Figure 6)
In that part of the tension screw shown in Figure 12 F10 is a recess or slot
extending longitudinally through its whole length into which fits the lower
portion of that part of the tension appliance shown in Figure 13, which 18 80
constructed, as to form a spring, lettered F4, hereinafter described
The upper portion F1 of Figure 13 forms top of tension sciew over which the
tension nut F shown in Figure 14 fits, engaging the screw thread F13 (Figure 12).
The spring portion F1 (of Figure 13) pressing against the interior of the
slot F10 (of Figure 12) keeps the key Fis in contact with the inner periphery
of the nut F which 18 consti ucted with a series of recesses to act as stops for the
purpose of locking the tension (as shown in Figure 7)
When it is desned to alter the tension the head F is pressed to the centre of
the aperture in the nut 1 thus releasing the key F from contact with the afore-
said stops and allowing the nut to be revolved as desired. The whole of these
parts constituting the tension appliance are shown in position in Figures 6 and ~.
In Figure 15 M is a bevelled gear wheel, N 16 a crank pin which may be pro-
vided with a roller for the purpose of reducing the friction Mis aperture in
wheel M through which spindle O (shown in Fig 17) passes and on which the
said gear wheel M revolves
Figure 16 shows portions of flexible transmitting shaft terminating in an
elongated bevelled pinion wheel P which engages gear wheel M and is shown in
position in Figure 17
A portion of the body of the bevelled wheel P 18 cut away, as shewn, for pur-
pose of forming a balance weight or fly wheel. Q is a connecting rod pivotted to
pinion wheel P by pin P R is bearing in which one end of pinion wheel P
revolves forming a collar within the handle H, as hereinafter described The
flexible shaft consists of a series of short lengths of tubing alternating with a
series of short rods connected by means of rivetted pins at each end, each pin
being at right angles to the preceding one
These tubes may be made evlindrical throughout or as shown in the drawings
with cylindrical interiors but having then exterior surfaces barrel shaped
SS are the tubes T T are the rods, U U are the pins pivotting tubes S Š to
10ds T T The flexibility of this shaft is obtained by having each alternate pivot
at right angles to the other, and by having the pivot holes in the rods TT
countersunk and of sufficient diameter to allow them free play To permit of
the greatest possible amount of flexibility, to this chain shafting both ends of

page_text: each of the tubes S S may be countersunk

J 18 a helical spring formed of wue and used as an inner cover for flexible
shafting J is outside coveung surounding saad helical sping and is made pie-
ferably of soft leather The method of fastening the wire spring covering J
to the handle of the machine is as follows One end enters a tube or socket W
the end of the wire being bent to pass through a slot WI in an interior
shoulder W' and to rest in the other side of the shoulder which is cup shaped,
a cored stuffing box W being screwed down to meet the shoulder thus holding
the end of the wire covering Je securely in position The tube W is also pio-
vided with an external shoulder W which with the flange W of the stuffing
box forms an annular recess embedding the shoulder H¹ on the interior of the
handle thus forming a bearing which secures the casing to the handle while at
the same time allowing it to revolve freely In order to secure the end of the
leather covering the outside periphery of the tube or socket W is made tapered
at one end (as shown) and the leather being forced over the tapered point thereot
is held in position by means of a jamb nut Wo The handle H is secured to the
mechanical chamber G by an overlapping joint as shown and held in position by
screw H. The other end of both the leather and the wire coverings of the
flexible shafting are secured in a similar manner to that just described with the
difference that the end of the wire is in this case secured by a small screw (as
shown) Z in place of the stuffing box W3 Z is a tube or socket connection
similar to W Z is jamb nut similar to W securing leather cover J This
connection terminates in a universal or ball joint of which X 18 the ball socket
and X the ball This ball X¹ 1s extended in the form of a tube X with an
internal diameter equal to that of the spring casing J¹ On the end of this tube
is screwed a socket X³ connecting it to another section of tubing X' of the same
diameter and of any desired length to form a covering for the shafting as shown
The flexible shafting shown in Figure 16 18 encased by the covering shown in
Figures 18 and 19, the connecting rod V terminating in the slotted tube Y
within the casing tube X as shown in Figure 19; the key V₁ gripping the edge
of the longitudinal slot Y¹ of tube Y thus forming a connection. The other end
of tube Y is fitted with an eye hole Ya which engages the hooked end of a rigid
steel shaft of any desued length. The shaft may be then continued by
another length of flexible shafting covered and jointed in a similar manner to
that herein before described and as shown in Figure 19 The sheft may be thus
continued to any desed length by alternate sections of rigid and flexible shaft-
ing jointed and covered as herein before described or if desired may consist of
one continuous length of flexible shafting.
X (Figure 19) shows a portion of tube covering rigid steel shafting 0. This
tube connects with the universal joint shown in Figure 20 (a) being ball
socket (a) the ball (a) screwed joint connecting casing X³ of Figure 19 to the
said universal joint

purpose of minimising the danger of breakage from possible obstructions

page_text: between the cutting blades (6) 18 a pulley or if preferred a sprocket wheel on
one side of which is a cap (61) of smaller diameter. This cap (b) may be an
integral part of pulley as shown or may be attached to it in any suitable way
The pulley and cap (b, b) fit over the end of and revolve on a hollow horizontal
shaft (d). Between the end of the hollow shaft (d) and the inside face of cap (6)
is a disc provided on one ade with a hollow boss (el) which acts as a bearing
and on the other with a screwed spindle (e) which passes through the end of
cap (6) as shown. A pin passes through the spindle () and projecting on either
side forms stops (e³) (e³) A flanged and slotted sleeve (f) (shown in detail in
Figures 22 and 23) fits over the spindle (e²) the projections (63³) fitting between
the slots (Figure 22). The sleeve (f) is provided with a sping catch (f³) for
the purpose of locking the tension nut (g), the toothed periphery of which t
engages. Between the flange of the sleeve (f) and the outside face of cap (6)
is a washer (f³) of almost the same diameter as the cap (6) (Figures 20 and 21)
The face of the disc (6) which butts against the inside face of cup (6) is provided
with a projection or nose (e) the inside face of cap (6) being provided with a
corresponding nose so that when the sping catch (4) is pressed forward and the
tension nut (9) is screwed up the face of the disc (e) is diawn into close contact
with the inner face of cap (6) and the washer (³) with its outside face, thus
gripping the pulley and revolving with it Should an abnormal obstruction
occur from any cause the nose (e) on the face of the disc (6) would ride over the
corresponding nose on the innei face of cap (61) the latter being constructed in
the form of a sping for the purpose, and thus prevent any breakage of the work-
ing parts of the machine
(h) is an internal shaft one end of which enteis and 18 secured to the hollow
boss (e) of disc (e) by means of the pin (h) (A) is a movable collar fitted on
shaft (h) and provided with a feathered key way (¹) the shaft (h)
being fitted with a corresponding key (h³) (L-³) 19 an annular recess
for the purpose of operating the collar or clutch (4) as hereinafter described
() are parallel tongues fitted on the end of collai (k) which when the collar
is moved forward engage corresponding tongues (181) on the end of bearing (¹)
of gear wheel (1) This movable collar oi clutch gear is provided for the purpose
of starting or stopping the machine and the method of operating same 18 shown
in Figure 24 which 18 a cross section through the annular recess () in
Figure 20. (m) 18 a lever bar or handle evolving on pivot (n) which is fixed
to bracket (p). (r) is a right angular thumb or pin which is attached to the
end of the lever (m) and passing through an aperture in the bracket (p) enters
the annular recess (13) so that by operating the handle (m) the collar (*) is moved
either backwards or forwards as required. In Figure 20 (t) 18 pinion wheel
engaging gear wheel (7) and revolving in bearing (10) fixed in right angular
aim (p) of bracket (p) To this pinion () which is coied as shown is attached
the flexible shafting as hereinbefore described by means of the pin (¹) The
pinion (t) is also piovided with anti-friction wheels (13 (2) on which it revolves,
the wheels themselves revolving on the pin (¹) The motive power is trans-
mitted from the main shaft to the pulley b, either by any suitable belting, or by
a chain if a sprocket wheel is used in place of a pulley as shown
When the pulley (6) 18 10tated (the tension nut (g) being adjusted) the
washer (f) on the one side, and the nose (et) of disc (e) on the other, grip the
cap (6) and are rotated thereby carrving with them the shaft (h) thus transmitting
the power to the wheel (7) by means of the keyed clutch (*) This gear wheel (7)
engages the pinion wheel (t) to which is jointed the flexible shaft in the manner
herein before described The other end of the shaft terminating in the pinion
wheel P (Figure 17) engages the gear wheel M which revolves on the spindle O
and operates the reciprocating lever L by means of the crank pin N (Figure 15)
which works in slot L thereof (Figure 7) thus changing the rotary motion of the
shaft into the necessary intermittent oscillating movement which is transmitted

page_text: by the thumb L (Figure 6) to the plate D (Figure 5) The movable blade I
being secured as herein before described to the plate D is operated thereby
B
The parts of the machine are so constructed and adjusted, that the teeth of the
movable blade B pass over those of the fixed blade A sufficiently far to allow of
the wool to interpose
•
The lower blade A is constructed slightly wider than the upper blade B, having
one more tooth. Figure 5 shows the movable blade in the position taken up
about the middle of its stroke, 16. with its teeth lying opposite the interstices
of the teeth of the fixed blade
Figure 1 shows approximately the position when the movable blade has
reached the end of its stroke towards the right, that is when the teeth of the
movable blade overlap those of the under excepting only that on the extreme left.
When the movable blade reaches the end of its stroke towards the left, the teeth
will again overlap but this time the tooth on the extreme right of the lower blade
will be uncovered It will thus be seen that every tooth of both blades cuts on
both sides (excepting those on the extreme right and left of the lower blade),
consequently the number of revolutions necessary to effectively operate this
machine is much less than in those hitherto in use which have only one cutting
blade
As
"
It will be seen from the foregoing that my machine differs not only in construc-
tion but in the essential principle of movement from all those now in use
in place of one blade moving on a comb at an enormous velocity and "chewing'
the wool the principle on which my machine works 18 a comparatively slow
movement by which the wool is cut between two sharp edges exactly as if shorn
by a pair of shears or scissors
