Improvements in Machines for Shearing and Clipping Wool and for
Cutting Hair.
We, JOHN MOFfat, Tin Smelter, and WILLIAM WRIGHT VIRTUE, Engineer,
both of 18 Bridge Street Sydney in the Colony of New South Wales, 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:―
These improvements relate to machines for shearing and clipping wool and for
cutting hair, ordinarily known as "Sheep Shearing and Horse Clipping Machines."
In these pieces of apparatus, rotary motion, transmitted by some form of flexible
shafting, is converted into reciprocating motion, which is applied to vibrating a
knife or cutter over a comb or gathering plate.
But in order that the invention and the method of using the same may be
easily understood, reference is had to the annexed sheets of explanatory drawings,
which are to be taken as supplementary to this Specification and read there-
with. Several of the chief features in the machines illustrated in the drawings
are interchangeable and are wholly or in part adaptable to many machines already
known.
Figures 1 and 2, 3 and 4, and 5 and 6 are respectively illustrative of the
first, second and third modifications of construction of the machine; a fourth
modification is described but not illustrated; Figures 15 and 16 are illustrative
of the fifth modification, and Figures 19 and 20 are illustrative of the sixth and
seventh modifications respectively. Figure 7 relates to Figures 1 and 2, Figures 8
and 9 to Figures 3 and 4, Figure 11 to Figure 3, and Figure 12 to Figures 5
and 6; Figures 17 and 18 relate to Figures 15 and 16, and Figures 21 and 22
to Figures 15, 16, 19 and 20. The application of one of the features of the
invention to a machine of known construction in which the knife-bar is a lever
of the third class, is illustrated in Figures 13 and 14.
Figures 1, 3, 5 and 15 are central longitudinal sections and sectional elevations
through machines constructed according to the present invention, and Figures 2,
4, 6 and 16 are part plans and horizontal sections corresponding therewith, respec-
tively; Figure is a transverse section on line a-b in Figure 1; Figures 8
and 9 are similar sections on lines c-d and e-f in Figures 3 and 4, respectively;
Figure 10 is a transverse section illustrating an alternative method of securing
the machine lid and capping the main oil hole; Figure 11 is a similar section
on line g-h in Figure 3; Figure 12 a similar section on line k-l in
Figures 5 and 6; Figure 13 is a sectional elevation of a machine of another
class, to which one of the features of the invention is applied; Figure 14 a part
plan and horizontal section relating to Figure 13; Figure 17 a transverse
section on the line m―n, Figure 15; Figure 18 a part exterior plan relating to
Figures 15 and 16; Figures 19 and 20 part plans and horizontal sections
illustrative of the sixth and seventh modifications of construction; Figure 21 a
longitudinal section through the tension distributing fork, and Figure 22 a plan
of same.
Neither of the tail connections shewn in Figures 1 to 6 for counline the

page_text: machine and the flexible shaft by which rotary motion is imparted to it, is
claimed as novel; being all interchangeable and non-essential to the successful
operation of the machines, there may be substituted for them any form of con-
nection that will allow the requisite flexion to take place close to the tail, and
transmit the motion of a flexible shaft or other source of power to the main
shaft of the machine.
The improvements included in the present invention cover methods of and
mechanism for converting rotary into reciprocating motion, tension mechanism, the
construction and combination of power transmitting and tension levers and parts
therewith connected, and generally, details either directly or indirectly connected
with one or other of these parts. Several modifications are shewn of each of the
more important pieces of mechanism. In nearly every case either of the modifi-
cations of one part are usable in combination with any of the modifications of the
other parts; thus the motion converting mechanisms shewn in Figures 1, 5, and 15,
are all interchangeable, whilst the same is also the case with the tension mechanisms
shewn in Figures 1 and 3; the construction and combination of the power and
tension levers shewn in Figures 19 and 20 and the tension gears used therewith
are similar to the construction and combination of like parts as shewn in Figures 1,
3, and 5.
In all the drawings, the same letters and figures of reference indicate corre-
sponding and like parts.
Referring particularly to Figures 1, 2 and 7, and to the portions of other figures
illustrating parts of corresponding construction, 1 is the main shaft, 2 annular oil
chamber about such shaft, 3 main bearing, 4 balanced disc or coupling, 5 overhung
excentric pin or shaft cored out to form an internal oil reservoir, 6 bush or bearing
fitting truly about the pin or shaft 5, and formed square exteriorly and exactly
fitting the space between the wings 11, 7 screwed plug and nut, 8 centre-block,
9 upper section of centre seating, 10 lower section of centre seating, 11 lever wings
or rearward extensions of brackets from the centre block 9, expanded and thinned
out at the edges as shewn in section in Figure 7, 12 knife-bar arms, which also
constitute the tension lever, centred at 13 on the lever wings 11, and capable of
moving at the forward end about such centre 13 perpendicularly to the plane of
vibration, 14 web uniting the arms 12 at the forward end, 15 knife or cutter plate,
16 dowels on the fingers of the knife-bar passing into corresponding holes in the
knife or cutter plate, 17 comb or gathering plate secured by screws 18 to the lower
lip 19 of the machine, 20 side jaws, 21 upper lip or nose-cover, which is either
secured by screws 22 as shewn in Figure 1 or made integral with the upper section 9
of the centre seating as shewn in Figure 3 or 5, 23 machine case or shell, 24 cover
plate, 25 cover plate locking spring, 26 tension screw, 27 cone point or ball head,
28 thimble seated in the upper section 9 of the centre seating, 29 washers, 30 tension
bridge pin, 31 slotted holes through the sides of the centre-block, 32 reaction
spring, 33 oil holes.
The axes of the shafts 1 and 5 if projected forward would cut one another in the
axis of vibration -y of the block 8, as indicated by dotted lines. These two
shafts and the coupling 4 may be either turned out of the one piece of metal, or
may be formed separately and secured together as shewn in Figures 1 and 5. The
bushing or bearing 6 is supported about the shaft or pin 5 and moves vertically
between the lever wings 11. The nut 7 acts as a plug for the foot of the oil
reservoir within the shaft or pin 5 and also serves as a collar to keep the bush or
bearing 6 in position thereon. Holes are provided to allow the passage of oil for
lubricating purposes from the oil reservoir before mentioned to the exterior side
surfaces of the pin or shaft 5 and to the interior and the exterior side surfaces of
the bearing or bushing 6 and to the interior side surfaces of the lever wings 11.
The thimble 28 is independent of the centre-block 8 and is made square exteriorly
in order to look itself in the upper section 9 of the centre seating, or otherwise it is
pinned or keyed therein; this thimble is tapped and the tension screw 26 moves
through it. When the thimble is used, the tension may be varied at will whilst the

page_text: machine is in motion. The centre-block acts only as the centre of motion, and when
the tension is varied it does not rock in a plane perpendicular to the plane of
vibration of the knife or cutter plate, as is usually the case in shearing machines.
Nut lock gear may be provided for preventing the tension screw from slacking
back.
The cover-plate encloses the upper half of the machine between the seating 9 and
the tail; at the forward end it is engaged by a snug as shewn in Figure 1, and
at the rear end it is provided with a finger piece which fits into a notch. If desired
the cover plate may be hinged.
Two forms of locking device are shewn in Figures 10 and 11 respectively, and
will be hereinafter described.
The centre-block 8 is turned to fit the seating, and when in operation vibrates
therein; it is integral with the lever wings 11 which extend rearwardly almost to
the coupling 4. There are in the sides of the block 8 two slotted holes 31 and
through these the bridge-pin 30 passes, and enters holes in the knife-bar 12 as shewn
in Figure 8. In proportion as tension is applied the spring 32 is compressed and
the bars 12 move downward towards the comb about the centres 13, but the
positions of the centre-block 8 and of the lever wings 11 are not varied; when the
tension screw is slacked back, the spring 32 raises the bars 12 about the centres 13
and relieves the pressure upon the knife-plate 15. There is no surplus play in any
part of the mechanism, slackness or undue vibration in working being prevented by
the spring 32, the action of which likewise effectively prevents the "sticking
of the parts, and thus facilitates the positive and exact application of the tension.
During each revolution every point in the parts 5 and 6 describes a circle, while
the part 6 itself describes the surface of the frustum of a cone.
Referring now to parts in Figures 3, 4, 8, 9 and 11 which do not correspond
substantially with parts performing like functions in the figures last described, 35 is
the motion disc or coupling, 36 checks thereon, 37 pin, 38 eye head of excentric pin
or coupling rod, 39 hollow excentric pin or coupling rod, 40 excentric bush or
bearing (in which the part 39 moves) formed square exteriorly, 41 pin set in the
wings 11 about which the part 40 moves, 42 centre-block, 43 foot plug in part 42,
44 tension screw, 45 and 46 washers, 47 hand guard, 50 main oil hole, 51 spring
bridge piece, 52 clasp springs.
In machines of this class of design the centre block may be either formed as
shewn in Figure 3 and provided with a foot-plug, or cast solid as shewn in Figure 8.
The thimble 28 as shewn in Figure 1 may or may not be used; when the block
itself is tapped the tension screw necessarily vibrates with it and the tension cannot
be varied whilst the machine is in motion. In other respects the tension mechanism
operates like that previously described. The guard 47 is only necessary when the
thimble is not used. The main oil hole 50 is enclosed by a leather cap set on a
spring bridge-piece 51 ; and the cover 24 is secured by clasp springs 52 which when
in the closed position appear as in Figure 11.
The chief difference in the design of the machines illustrated in Figures 1 and 3
lies in the mechanism for transforming motion. The operation of the-device
shewn in the latter figure will be readily understood on reference thereto. The
part 40 reciprocates vertically about the pin 41, while within that part the part 39
rotates, reciprocating with it; the latter part also moves slightly about the
pin 37. Every point in the parts 39 and 40 except the centre 41 describes an
ellipse in each revolution. The nose cover plate 53 is preferably cast in one piece
with the part 9.
Referring to the parts in Figures 5, 6 and 12 which do not correspond substan-
tially with parts performing like functions in Figures 1 and 2, 55 is the centre-
block, 56 knife-bar, 57 shoe, 58 eye in rear end of knife-bar, 59 jaws or wings
extending forward from the centre-block 55, 60 hollow pin, and 61 nut securing
same.
In this design of machine the method of transforming motion is analogous to that
employed in the design illustrated in Figures 1 and 2, the main points of difference

page_text: being confined to the tension gear, and to the construction of the centre-block and
its attachments and their combination with the knife-bar. Unlike the examples
shewn in previous figures the knife-bar is not bifurcated. It passes through a
rectangular aperture in the centre-block and is grasped on either side by the
jaws 59 forward of the centre and by the lever jaws 11 rearward thereof. At the
rear end a hollow pin 60 passes through the wings 11 and the eye in the boss 58,
and about this pin the lever 6 moves when the tension is varied. The tension
Ecrew may be seated either in a thimble, or in the solid centre-block as shewn in
Figure 8. The tension is applied directly upon the shoe 57 which is embedded in
the knife-bar. The operation of the motion mechanism is precisely analogous to
that shewn in Figure 1, and will be understood on reference to the part of the
present Specification relating thereto. An interrupted spring ring 62 sliding in a
grove around the part 4 is employed to close the oil hole leading to the oil reservoir
within the pin 5. In lieu of the cover clasp gear shewn in Figures 3 and 11, that
shewn in Figure 10 may be employed.
A tension lever of the first class may be combined with the power lever last
described. In such an arrangement the wings or jaws 59 are extended further
forward than shewn, and a pivot-pin is inserted through them and through the
tension lever to allow the latter to be moved about it relatively to the power
lever at right angles to the plane of vibration. As the details of such a construc-
tion will be at once evident to any skilled mechanic, it is unnecessary to describe
the same.
If desired, the thumb-piece of the tension screw may be omitted, and a keyway
formed in the screwed spindle 26 fitting a key or equivalent device of convenient
form for regulating the tension.
Referring to Figures 13 and 14, 63 is the main shaft, 64 collar or disc,
65 excentric pin, 66 bushing or bearing thereon, 67 nut, 68 centre pivot, 69 knife-
bar, 70 cheeks, 71 shoc, 72 tension roller, 73 machine case, 74 comb, 75 knife or
cutter. These figures indicate the mode of applying the invention to a form of
machine already well known and in use. Hitherto, in machines of this class, a
cheese roller, which is overhung excentrically from a disc such as 64, and works
between cheeks such as 70, has been employed to give motion to the knife-bar; but
this construction brings about rattling and loose working and consequent heating of
the parts, and to avoid these disadvantages is one of the aims of the present
invention. The operation of the device will be readily understood on reference to
the drawings.
In lieu of the tension genr illustrated, a "mushroom" piece similar to that shewn
in Figure 13, or other form of rolling contact bearing down on the knife-plate, and
gear for applying pressure thereto, may be provided over the nose of the machine.
The application of tension in this manner is already well-known and need not there-
fore be described, the means and necessary mechanism ordinarily employed for the
purpose being capable of adaptation to the machines herein described by the
exercise of ordinary mechanical skill.
In machines where one lever is adapted to operate both as power lever and knife-
bar, the excentric pin or shaft with or without the bush 6, or the modifications of
that construction which have been already described, may be employed to vibrate
the lever, at the rear end of which jaws or cheeks in which such pin or shaft 5 moves,
may be formed.
Referring to Figures 1 to 12, and to Figures 19 and 20, the centre-block may
be made to run in ball bearings, and the tension may also be applied through
these devices. The centre-block and tension gear and the mechanism for converting
motion are capable of use in and adaptation to known machines independently of
each other.
Referring to Figures 15, 16, 17, 18, 21, and 22, 80 is the main shaft, 81 main
bearing, 82 balanced disc or coupling, 83 motion block, 84 spindle of block 83,
85 turned shoulder, 86 screw plug, 87 oil reservoir, 88 power lever, 89 cross heads
on power lever, 90 knife edges set in the cross heads 89, 91 face plates set in

page_text: as to
machine body against which the knife edges 91) bear, 92 round or conical point,
93 hardened seating, 94 lower section of machine centre seating, 95 upper
section of machine centre seating, 96 tension lever, 97 shoe, 98 intermediate
tension lever, 99 ball head thereon, 100 tension screw which works through the
part 95, 101 tension locking spring, 102 tension lever centre pin, 103 turned
shoulder on tension lever, 104 head of tension lever, turned and cut down on
upper side as shewn, 105 tension distributing fork, 106 ring on stem of part 105,
107 spring claw, 108 screw, 109 dowels, 110 cutter or knife, 111 comb,
112 upper jaw or nose cover, 113 machine case, 114 cover plate, 115 oil holes.
The motion converting device is a modification of the construction shewn in
Figures 5 and 6. The part 82 is swelled as shewn, and through the swelled
portion a hole is bored on a centre which, if produced, would, irrespective of
the position of the disc 82, cut the axis of vibration m-n at the point of inter-
section of the latter with the centre line of the main shaft produced. In this
hole the shank or spindle 84 of the motion block 83 is fitted truly so
rotate freely but without play; this shank or spindle is bored to form an oil
chamber within it, and the end of this oil chamber is filled by a cheese head
screw 86 which takes against the back of the part 82 and keeps the motion
block in position. The operation of the device will be readily understood on
reference to the drawings; it is analogous to that of the equivalent mechanism
shewn in Figures 5 and 6. The pressure at the centre is taken on knife edges
and points. The power lever 88 is formed with two cross heads or T-piece 89
which carry the knives 90. The knives may be formed either with rounded or
sharpened edges, and the face plates 91 are formed accordingly; rounded edges
are shewn in the drawings. The lower knife is brought to a round head or cone
point 92 at the foot and this is supported against a hardened plate or seating 93.
The tension lever 96, except at the head, is formed like the tension lever 56
shewn in Figures 5 and 6, and it is set between the jaws of the power lever
in a similar manner. As, however, the construction of the power lever 88 is
such that the tension screw cannot be made to bear directly upon the shoe 97,
an intermediate lever 98 having a ball or cone head 99 is provided. This lever
is formed with expanding claws at the forward end which take against a step
in the under part of the upper jaw or nose cover 112; at its rear end bears a
tension screw 100 which passes through a tapped hole in the part 95. The
portion of the pressure exerted by the screw 100 upon the part 96, which is
transmitted from that part to the part 88 through the pin 102, suffices to keep
the point 92 upon its seating, and thus the proper position of the power lever
is maintained. The tension locking spring 101 consists of a light steel strip
with a pawl adapted to engage the detents on the under surface of the thumb-
head of the screw; when the spring is in its normal position the screw can only
be operated to increase the tension, but when it is held down the tension screw
can be rotated freely in either direction. In an alternative arrangement, the
seatings are set on the lever, and the knives in the parts 94 and 95. At the
head the tension lever 96 is provided with a turned shoulder 103 and forward
of this shoulder the lever is turned on its own centre and the turned part 104
is cut away at an angle as shewn in Figures 21 and 22. The tension distributing
fork 105 is formed to clasp the round of the part 104, and the ring or collar 106
which is integral with the part 105 embraces the part 104. The spring claw 107
is formed as shewn in Figure 1, and bears down at the point upon the middle
tine of the cutter; it is screwed to the part 104 and forms a stop against the
collar 106 to prevent the part 105 from being lifted out of position relatively
to the part 104. The part 105 can move slightly about the part 104 to adjust
itself to the plane of the upper surface of the cutter and thus equally distribute
the tension thereon. We are aware that other devices are known for distributing
the tensional pressure upon the cutter one such being described in the Specification
of the Patent granted to Charles Burgon and Harry Burgon No, 5317 of
1891.

page_text: Referring to Figure 19, 120 is the main shaft, 121 main bearing, 122 balanced
disc or coupling, 123 overhung excentric pin or crank, 124 centre block, 125 lever
wings extending rearwardly therefrom, 126 jaws or wings extending forward
from the centre block, 127 tension lever, 128 tension lever centre pin, 129 shoe
for tension screw, 130 forked link or connecting bar, 131 machine screws
pivotally securing same to the part 124 across its centre of vibration, 132 bored
end of link 130 fitting the part 123, 133 oil chamber, 134 lower section of
centre seating, 135 lower jaw of machine, 136 machine cheeks, 137 machine
case, 138 oil holes, 139 machined faces. In this design the motion is converted
from rotary into reciprocating by the action of the overhung pin 123 and the
forked link 130. The centre-block 124, and the combination therewith of the
lever wings 125 and 126 and the tension lever 127 is similar to that illustrated
in Figures 5 and 6, and need not therefore be described in detail. The link
or bifurcated connecting piece 130 is pivoted across the centre of vibration by
the machine screws 131 and at the rear it is bored to fit the pin 123. In
operation its machine jaws reciprocate vertically in sliding contact with the
adjacent exterior part of the lever wings 125, whilst the component of the rotary
motion at right angles thereto is spent in freely reciprocating the part 130 in
a vertical direction between the lever wings 125. The pin 123 is turned on a
centre which if produced would cut the axis of vibration at its point of inter-
section with the centres of the pins 131; it is bored hollow to form within it
an oil chamber 133, and to reduce its weight.
The centre block 143
Referring to Figure 20, 140 is the main shaft, 141 main bearing, 142 balanced
disc or coupling, 143 centre block, 144 rearward wings or extensions therefrom,
145 hollow machine screws set in the sides of the block 143, and carrying the
eyes of the excentric driving lever 146, 147 turned head of lever 146, fitting a
hole of corresponding form in the part 142, 148 forked tension lever, 149 tension
lever centre pins, 150 tension bridge pin, 151 tension screw, 152 oil chamber,
This
153 oil holes, 154 lower section of centre seating, 155 machine case.
design is a modification of that shewn in Figures 3 and 4.
is formed with lever wings 144 to the rear of which legs 148 of the tension
lever are pivoted by means of machine screws 149. Hollow machine screws 145
are set in the centre-block, their axes being in line and cutting the axis of
vibration. On these screws the motion bar 146 reciprocates at right angles to
the plane of vibration; it is formed with parallel faces which move in sliding
contact between the lever wings 144, and at the rear end is turned to a cylindrical
pin 147 which is bored as shewn to reduce its weight and to form within it an
oil chamber 152. The tension screw 151 takes against the tension bridge pin 150
as shewn in Figure 1 or 3, and the tension bridge pin is set hard in the legs
of the tension lever as previously described. Sufficient clearance is provided
within the hollow screws 145 to allow the requisite motion to the pin 150 when
the tension is varied. The hole in the part 142 in which the pin 147 moves is
bored on a centre, which, if produced, would cut the axis of vibration at its
point of intersection with the axis of the pins 145.
The parts for gyrating the levers 130 and 146 are interchangeable; and any
device may be substituted for either of them which will effect the gyration of
these levers in the manner described.
We are aware that shearing machines have been known in which there is an
overhung pin, or a pin and roller projecting from a rotating disc and moving
in a slot or way formed in the tail of the knife-bar; and it is further within
our knowledge that machines exist in which a forked connecting link in
mechanical connection at the rear end with a rotating disc grasps the tail of
the knife-bar and is pivotted thereto near or across the centre of vibration.
We desire it to be understood, however that all existing forms of shearing and
clipping machines comprising these features have mechanical faults and imper-
fections which are not to be found in the present invention; moreover, the
methods of application of such of these principles of construction and operation

page_text: as are set forth in the claiming clauses which follow, are materially different
from the methods previously employed, and embody features of utility and
mechanical value which known constructions of machines do not possess.
We would have it understood also that known shearing and clipping machines
wherein are combined a power lever of the first class, a tension lever of the
third class, tension gear at the common centre of vibration, a bell crank on the
power lever, and a pitman for communicating reciprocating thereto have mechanical
disadvantages of considerable moment, and have been superseded in use by other
machines which do not embody such constructions; we disclaim the combination
of a power lever of the first class and a tension lever of the third class, in so
far as the existence of such previous combination renders it legally necessary
to do so. Subject always to this limitation, we desire the claiming clauses
which follow to be read as not confining us to the special constructions of parts
described.
Having now particularly described and explained the nature of our said inven-
tion and in what manner the same is to be used, we declare that what we
claim is :-
