MoNaught at the Office of the Commissioners of Patents on the 1st March
1882.

IN OR APPLICABLE TO MACHINERY FOR SCOURING AND WASHING WOOL AND
OTHER FIBROUS MATERIALS
"
Firstly, Our invention relates to the mechanism for propelling the wool in, and
delivering it from, the trough of wool washing machines, and consists in combining
excentric toothed wheels, or other known equivalent mechanism, with the shafts
rotating the cranks for actuating the propelling and delivering forks, prongs or
toothed frames, so that the shafts will rotate at a slow speed when the teeth or
prongs are moving forward and operating upon the wool, and at a quick speed
when moving backwards without operating upon the wool, in the washing trough.
Secondly, Our invention relates to mechanism for propelling wool in, and
delivering it from a washing trough, when the trough is so arranged that the wool
is delivered from the trough at one end and at or about the level of the liquor in
the trough.
One modification of our invention consists in a frame armed with prongs, which
frame extends the greater part of the length of the trough.
This frame has motion given to it by cranks, cams or other equivalent mechanism,
so that its prongs will descend towards the bottom of the trough and then move
forward towards the delivery end of the trough, and at the same time rise to some
extent so that the teeth at the delivery end of the frame will push the wool submerged
in the liquor up the incline or curve of the trough at the delivery end and
discharge it over the top of the incline which is at about the level of the liquor in
the trough to then pass on to the squeezing rollers.

page_text: The toothed frame then moves upwards and back wards and then descends again
and moves forward as before.
The wool passes to the squeezing rollers either down rollers or an endless apron
forming an incline, or down a fixed smooth incline, (as we prefer) and the liquor
passing from the wool after being delivered from the washing trough is collected
in a trough or vessel the bottom of which is below the lower squeezing roller, and
is afterwards pumped or otherwise lifted back again into the washing trough.
According to another modification of our invention, the toothed frame is formed
in two parts, the frame at the front which acts to deliver the wool from the trough
is hinged or jointed to the other part of the frame, the teeth of which act to
propel the wool along the trough.
The hinged part of the frame for delivering the wool, may be separated from the
other frame and actuated separately, but we prefer the two parts of the toothed
frame to be hinged or jointed together.
The two parts of the frame are or may be arranged in any convenient manner
and worked to and fro and up and down by a can or cans and cranks or other
equivalent mechanism.
But we prefer to arrange and work the toothed frames by suspending them on
rods, chains or other supports which forms an important feature of our invention.
In the case of rods and where there is only one toothed frame both for propelling
and delivering, we joint the frame to the lower ends of the rods, the upper ends
of which are jointed to an arm or arins from two shafts above, carried in suitable
bearings.
By these arms and a cam or cams and suitable connections, the point of suspension
of the rods can be raised and lowered and by a crank and connections the toothed
frame has to and fro motion imparted to it in the lengthway of the trough, and by
excentric wheels according to the first part of our invention the crank shaft has a
slow and quick speed imparted to it so that the toothed frame will move slowly in
going forward and quickly going backwards.
When the toothed frame is in two parts, it is suspended when rods are used as
when in one frame, and there is or may be a tie from the front end of the
delivery frame to the suspending rod or rods at that end of the propelling frame.
When chains or flexible attachments are employed, the upper ends are attached
to pulleys, instead of arms, on the shafts, and when chains are used the toothed
frame may be wound up and lifted away clear of the trough when required, and
the same may be done when rods and arms are used but not so conveniently.
When the toothed frames are in two parts hinged or jointed together, the
delivery frame moves in a curve to about the radius of the suspending rods or
chains.
Thirdly Our invention relates to means for readily cleaning out and discharging
along with the liquid contents of the washing trough the mud and sediment which
accumulates below the false or perforated bottom of the trough.
The liquor is generally discharged through an outlet or outlets situated in the
bottom of the trough which is closed whilst the machine is working and opened
when the liquor has to be discharged.
Our invention consists in arranging a jet or jets of steam in the space between
the bottom and the false bottom of the trough so as to induce a current in
the liquor contained therein by which the mud and sediment which has settled
underneath the false bottom is swilled out and discharged through the outlet or
outlets.
This jet or jets of steam is or may be arranged to act upon the principle of the
injector for steam boilers, and the steam is turned on at the time the liquor is to
be discharged. The current of liquor induced by the jet or jets of steam acts to
loosen and stir up the mud and sediment and to mix it with the liquor that is
being discharged from the trough whilst the outlet or outlets is open.

by the said John MoNaught and William MoNaught in the Great Seal
Patent Office on the 30th August 1882.

Rochdale, in the County of Lancaster Engineers and Machinists. "IMPROVEMENTS
IN OR APPLICABLE TO MACHINERY FOR SCOURING AND WASHING WOOL AND OTHER
FIBROUS MATERIALS."
Firstly, Our invention relates to the mechanism for propelling the wool, in and
delivering it from the trough of wool washing machines, and consists in combining
excentric toothed wheels or other known equivalent mechanism for producing
quick and slow rotary or reciprocating motion with the propelling and delivering
forks, prongs or toothed frames so that they will move at a slow speed when the
teeth or prongs are moving forward and operating upon the wool, and at a quick
speed when moving backwards without operating upon the wool in the washing
trough.
Secondly Our invention relates to mechanism for propelling wool in and
delivering it from a washing trough when (as we prefer) the trough is so arranged
that the wool is delivered from the trough at one end, at or about the level of the
liquor in the trough, though our mechanism will operate in a satisfactory manner
when the wool is delivered above the said level.
One modification of our invention consists in a frame armed with prongs which
frame extends the greater part of the length of the trough.
This frame has motion given to it by cranks cans or other equivalent mechanism
so that its prongs will descend towards the bottom of the trough and then move
forward towards the delivery end of the trough, and at the same time rise to some
extent so that the teeth at the delivery end of the frame will push the wool sub-
merged in the liquor up the incline or curve of the trough at the delivery end, and
discharge it over the top of the incline which is (by preference) at about the level
of the liquor in the trough to then pass on to the sqeezing rollers.
The toothed frame then moves upwards and backwards and then descends again
and moves forward as before.
The wool passes to the squeezing rollers either upon rollers or an endless apron,
or down a fixed incline (as we prefer) and the liquor passing from the wool after
being delivered from the washing trough is (as we prefer) collected in a trough or
vessel the bottom of which is below the lower squeezing roller and is afterwards
pumped or otherwise lifted back again into the washing trough.
According to another modification of our invention the toothed frame is formed
in two parts, the frame at the front which acts to deliver the wool from the trough
is hinged, jointed or connected to the other part of the frame the teeth of which
nct to propel the wool along the trough.
The hinged or connected part of the frame for delivering the wool may be
separated from the other frame and actuated separately, but we prefer the two parts
of the toothed frame to be hinged or jointed together.
The two parts of the frame are or may be arranged in any convenient manner
and worked to and fro and up and down by a cam or cams and cranks or other
equivalent mechanism.
But we prefer to arrange and work the toothed frames by suspending them on
rods, chains or other supports, which forms an important feature of our invention.
In the case of rods and where there is only one toothed frame both for propelling
and delivering, we joint the frame to the lower ends of the rods, the upper ends of

page_text: which are jointed to an arm or arms from two snarts above carried in suitable
bearings.
By these arms and a cam or cams and suitable connections, the point of
suspension of the rods can be raised and lowered, and by a crank and connections
the toothed frame has a to and fro motion imparted to it in the lengthway of the
trough and by excentric wheels according to the first part of our invention, the
crank shaft has a slow and quick speed imparted to it or a crank is arranged to
act on a slotted lever so that the toothed frame will move slowly in going
forward and quickly going backwards.
When the toothed frame is in two parts it is suspended when rods are used, 1
as when in one frame, and there is or may be a tie from the front end of the
delivery frame to the suspending rod or rods at that end of the propelling
frame.
When chains or flexible attachments are employed (as we prefer) the upper ends
are attached to pulleys, instead of arms, on the shafts, and when chains are used
the toothed frame may be wound up and lifted away clear of the trough when
required, and the same may be done when rods and arms are used, but not so
conveniently.
When the toothed frames are in two parts, hinged, jointed or connected together
the delivery frame moves or may move by preference in a curve to about the radius
of the suspending rods or chains.
Our improved combinations of toothed propelling and delivery frames are or
may be used in combination with the ordinary immersing drum, but we find that
the latter may be dispensed with and a more perfect substitute obtained by adding
a perforated plate, grid or sieve (which forms one feature of our invention) to the
feeding end of the toothed frame, which comes flat down upon the wool or
material fed into the trough as the frame descends and immerses the material while
the prongs under the immersing perforated plate, grid or sieve, propel the material
forward at the same time.
Thirdly, Our invention relates to means for readily cleaning out and discharging
with the liquid contents of the washing trough, the mud and sediment which
accumulates below the false or perforated bottom of the trough.
The liquor is generally discharged through an outlet or outlets situated in the
bottom of the trough which is closed whilst the machine is working and opened
when the liquor has to be discharged.
Our invention consists in arranging a jet or jets of steam in the space between
the bottom and the false bottom of the trough, or in a pipe outside and communi-
cating with the ends of the trough, so as to induce a current in the liquor contained
therein in one direction by which the mud and sediment which has settled
underneath the false bottom is swilled out and discharged through the outlet or
outlets.
The current of liquor induced by the jet or jets of steam, acts to loosen and stir
up the mud and sediment and to mix it with the liquor that is being discharged
from the trough whilst the outlet or outlets is open.
Fig 1 is a longitudinal section and elevation, fig 2 is a cross sectional elevation,
the section being taken through the trough at the discharge outlet, the elevation
being that of the deilvery toothed frame, and fig 3 a plan section taken below the
false or perforated bottom, these figures illustrating the mode of carrying out parts
of our invention.
Fig 4 is a longitudinal section and elevation, and fig 5 a cross sectional elevation,
the cross section of the trough in this figure also being near the discharge outlet
from the trough, illustrating other parts of our invention.
Fig 6 is a longitudinal section and elevation, showing a partial outside elevation
at the feeding end of the machine; fig 7 is a cross sectional elevation, the section
through the trough being near the feeding end of the machine; fig 8 a side
elevation, and fig 9 a cross section of the trough through the elevating wheel.
These figures illustrating other modifications of our invention.

page_text: Fig. 10 is a longitudinal side. elevation; fig 11 an end elevation; fig 12 a longi-
tudinal elevation in section, and fig 13 a cross section of a machine arranged
according to another modification of our invention.
Figs 14, 15, 16, and 17 are views corresponding respectively to figs 10, 11, 12
and 13 of a machine according to another modification of our invention.
a is the trough; a' its perforated or false bottom; a² the incline or curve from
the false bottom to the preferred working level of the liquor; a* the reverse
incline to the ordinary squeezing rollers b; c the ordinary feeding apron; & the
ordinary immersing drum.
Though not shown in all the illustrations, we prefer to arrange an open vessel a³
to come under the lower sqeezing roller (as shown in figs 6 and 8) to collect the
liquor discharged with the wool or material and expressed by the squeezing rollers,
and to connect this vessel a³ by a pipe a with another vessel a attached to the
side of the trough a and to arrange a series of buckets or scoops e¹ on a wheel e to
rotate on a stud e on the side of. the trough, this wheel being slowly rotated by a
belt from any convenient moving part of the machine, so that the buckets will
partly fill when in their lowest, and discharge in their highest position into a
vessel a secured to the side of the trough, and having an outlet from it through
which the liquor elevated will flow into the washing trough a.
Figs 1 and 2 show a wool washing machine in which a series of ordinary swing
rakes fare combined with a toothed delivery frame g, arranged according to our
invention.
The ordinary swing rakes fare actuated by cranks, on shafts f¹ which have
bearings on the side of the trough a, at one end, and on brackets adjustable on a
longitudinal bar f³ carried on the framing (as shown) at the other end.
The swing rakes swivel at their upper ends in brackets also carried on a
longitudinal bar f³ attached to the framing.
The crank shafts f' are geared together by spur wheels as indicated by peculiar
dotted lines and these wheels are also in gear with a wheel on a stud in the side
frame which wheel has an excentric toothed wheel g¹ upon its axis in gear with a
corresponding wheel g² on the shaft for the toothed delivery frame g which has
thus a slow and quick motion imparted to it.
This delivery frame g bas its teeth arranged in the segment of a circle and the
upper end of the stem g' to which the toothed frame g is attached is jointed to the
upper end of a bar g³ arranged to slide vertically in guides attached to or forming
part of the framing.
When the upper end or joint of the stem g' is stationary as when the toothed
frame is delivering the material, the latter moves in a curve to a radius from the
joint of the stem g' the curve at the bottom of the trough at that part being made
to a corresponding radius.
The crank pin that gives to and fro motion to the stem and toothed frame has
a block or bowl upon it that slides or rolls up and down in a slot in the stein gʻ
and when the toothed frame g has moved forward nearly to its greatest extent,
there is a cam go on the shaft g³ shaped to act upon the bowl at the lower end of
the slide g to lift the joint of the stem g' and hold it up while the frame g is
passing back, and then lower it again for the forward stroke.
The combined movements of the crank and cam cause the points of the first row
of prongs to describe the figure shown by the dotted line and small circles g7, the
path of the points of the prongs of the next swing rake f to the delivery frame g,
being shown by the figure f4.
The joint of the stem g' for the toothed frame g may also be arranged on a lever
having its fulcrum on the framing and the bowl for the cam on another lever
having also its fulcrum on the framing the two levers being connected by a rod
jointed to each lever.
The excentric wheels are arranged to give the slow motion when the toothed
frame is delivering and the quick motion when making the return stroke.

page_text: Figs 4 and 5 illustrate a machine where one toothed frame is used for immersing
and propelling wool or other material in and delivering it from a washing trough.
his the frame formed of two longitudinal side bars which are or may be tubular
to reduce weight.
These side bars are connected by cross bars to which the prongs or teeth h³ are i
secured.
a' are standards from the sides of the trough to carry the bearings of two cross
shafts h having pulleys secured upon them.
One chain h³ is secured to each side bar at each end, and the other ends of these
chains are attached to corresponding pulleys h* on the shafts h² which are
connected to move together by a chain 5 between corresponding pulleys hª on the
shafts h³.
There is a pulley h7 on the outside end of one shaft hs which has one end of a
chain attached to it, the other end being secured to a lever i having its
fulcrum on a bracket on the side of the trough,
This lever i has a weight upon it to partly counterbalance the weight of the
toothed frame h.
The lever i is made with a slot in it to carry a bowl and give space for a cam i³
to act upon the bowl and pass through the slot in the lever, but the bowl may be
on a stud in the side of the lever.
This cam is on one end of a cranked shaft ; having its bearings on the
framing, which crank is connected by two rods with brackets on the side bars of
the toothed frame h.
are the fast and loose pulleys on a stud in the side frame.
There is a pinion on the "fast" pulley which drives a wheel on a stud that has
an excentric wheel upon it, that drives one j' on the crank shaft j so that the
toothed frame will move slowly while propelling, and quickly when making its
back stroke.
The combined movements of the crank j and can cause the points of the
prongs to describe a figure similar to that shown by the dotted line *, the points
of the prongs rising as they move forward in an incline about parallel to that of
the incline a², up which the material is delivered from the washing trough.
It will be obvious to a mechanic that rods and arms may be substituted for the
chains and pulloys.
1º is the perforated immersing plate, grid or sieve which extends nearly across
the trough under and secured to the side bars of the frame h, and in some cases is
or may be made to extend the greater part of the length of the frame. There are
prongs arranged underneath it secured to the frame in any convenient manner.
The immerser is or may be formed of a sheet of copper or brass perforated on its
horizontal surface or of sieve wire work to afford free passage of the liquor through
it upon its sinking into and its rising out of the same.
All the edges of the immerser are turned up sufficiently high to prevent any
particles of wool from floating on to its upper side when it is down in its lowest
position in the liquor.
This immerser plate hº descends upon the material fed to the trough between
each downward stroke of the plate and immerses it, the prongs carrying it forward
at the same time.
In the modification of our invention illustrated by figs 6, 7 and 8 the propelling
part of the toothed frame h is arranged, suspended and actuated as hereinbefore
described in reference to figs 4 and 5 with the exceptions hereinafter mentioned,
but that part of the toothed frame 10 which both propels and delivers the wool
from the trough is hinged or jointed to the other part of the frame at h¹.
The front end of the toothed frame has a chain attached to it which passes
over a guide pulley h¹ loose on one shaft h² and then to a sinall pulley ¹ fast on
the other shaft h".
The combination of the movements of the crank and cam is such as to cause the

page_text: points of the prongs of the toothed propelling frame h to describe the figure similar
to that formed by dotted line and small circles h*, and to cause the points of the
last row of prongs at the end of the delivery frame to describe a figure in dots
and circles, similar to 1.
The lever i has its fulcrum ¹ on a stud on the side of the trough, and the
cam is on a stud or short shaft driven by a toothed wheel in gear with a pinion
on the fast driving pulley, both fast and loose pulleys being on a stud in the
side of the frame.
The pinion on the fast pulley drives a wheel on the end of a shaft k in bearings
on the side of the trough, which shaft has a crank at one end, the pin of which
has a block k¹ on it which slides in a slot in an arm k² on the end of a cross shaft k³
in bearings on the sides of the trough, and the other end of this shaft has a
corresponding arm /³ upon it.
The ends of the arms ³ have bosses jointed to rods 7 connecting them with the
side bars of the toothed frames.
The shaft passes through a tube between the sides of the trough or it may
pass outside the end or through a gap in the end of the trough.
The arm or lever at one sido has a curved slot for the shaft k. which passes
through it, as shown in dotted line fig 8, and this shaft forms the axis for the
inner roller of the feeding apron c
The crank is rotated in the direction shown by the arrow (fig 6) and acting
through the slotted arm or lever k² produces a slow forward motion of the toothed
frames h and 10 when propelling the material in the trough, and a quick back
motion when returning out of the liquor.
It is obvious that rods and arms or levers may be used for the compound toothed
propelling and delivering frames in place of chains and pulleys.
By depressing the weighted levor i and hooking or otherwise holding it down,
the toothed frame or frames is suspended out of the way above the trough when
required.
Figs 14 to 17 inclusive illustrate a machine according to our invention having a
toothed frame both for propelling and discharging actuated to produce the same
movements and action in the toothed frame as that illustrated by figs 4 and 5, but
differently carried and actuated.
There are bars across the frame, bent down over the sides of the trough, and
baving feet 7 resting upon antifriction bowls l' on bell crank levers 1³, having their
fulcrum on the sides of the trough.
The two bell-crank levers on each side of the trough are connected together by
a rod or rods and to an arm 1º on a cross shaft in suitable bearings on the end
of the trough. This shaft 7 has an arm on each end for each side of the trough,
and another arm on one end for a weight lever i the weight partly balancing the
weight of the toothed frame 7.
This lever i also carries a bowl, which works against the face of a cam i³ shaped
to give the required up and down movements, and this cam is on a separate shaft
or is or may be on the shaft which forms the axis of the immersing drum d, and
has or may have also cranks on each end, or one crank is or may be in a wheel
driving the immersing druin, and these cranks are connected by rods j¹ with the
side bars of the toothed frame h.
In the modification illustrated by figs 10 to 13 inclusive, the mechanism is
arranged and actuated same as that shown and described in reference to figs 14 to
17 inclusive, except that the movements imparted to the toothed frames are similar
to those hereinbefore described in reference to figs 6 and 7.
In this case there is a stem m rigidly connected with the toothed delivery
frame which ascends vertically and can slide freely through a swivel bracket m¹
in an arm or upright a secured to the side of the trough a, or the upper end of the
stem is or may be jointed with a radius rod having its fulcrum on the framing, and
this arrangement causes the delivery toothed frame 10 to move in a curve in a
radius from the swivel m³, when the toothed frame is making its forward or

page_text: delivery stroke and then permits it to lift pass backward and descend again for the
next forward movement.
The illustrations show the toothed frames combined with the ordinary immersing
drums & but these are or may be dispensed with and a perforated plate, grid or
sieve on the feeding end of the toothed frame h, used instead as hereinbefore
explained.
A quick and slow motion is or may be imparted to the toothed frames h and h¹º
by eccentric toothed wheels, one on the crank shaft in gear with one on a separate
axis, as herein before described in reference to figs 1 and 2.
Or the toothed frames have or may have to and fro motion imparted to them by
a crank or cam acting upon a lever from which the movement is transmitted to the
toothed frame h and 10 in a manner the same or similar to that hereinbefore
described and illustrated by figs 67 and 8 of the drawings.
The toothed frames illustrated in the drawings are each shown at the middle
positions of their forward stroke, as when propelling and delivering, except the
frame g figs 1 and 2, which is shown at the commencement of its forward stroke.
In some of the hereinbefore described modifications of our invention the toothed
frames are suspended, supported or arranged with the points or centres of support
or oscillation above the toothed frames, but it is obvious that they may be also
supported or carried and mude to oscillate on rods centred below the level of the
toothed frames, in which case the curves of the delivering toothed frame will be
reversed; and the toothed delivery frame need not move in a curve, but may if
desired, be carried, arranged and connected with the toothed propelling frame so
that the former will lift or ascend at the time it is propelling or delivering, and
thus move, so that the points of its teeth will describe a straight oblique line
parallel to the incline of the trough at the delivery end, when it is made straight;
but we prefer the arrangements illustrated as the most simple and convenient for
carrying our invention into effect.
We are aware that toothed frames or harrows for propelling wool in, and also for
delivering it from washing troughs are not new in themselves, as we invented and
patented the same previous to the date of our present invention, but we believe
that toothed frames which both propel the material in the washing trough and
deliver it therefrom according to our present invention are new, and have not been
before used.
Toothed frames or harrows have also been invented and patented by us prior to
our present invention, where one toothed frame or harrow for propelling the wool
along the trough has been combined with two alternately acting toothed frames for
delivering the wool at a level much above that of the liquor in the washing trough,
but we believe that a single toothed frame for propelling, combined with one for
delivering the wool according to our present invention is novel, and has not before
been used,
We have also previous to the date of our present invention, invented and
patented modes of actuating toothed frames or harrows where the up and down
movement has been effected by cams acting upon flat surfaces, which were directly
connected with and partook of the to and fro movement as well as the up and down
movement of the toothed frames, which surfaces slided upon the cams, but by
such arrangement of cams acting upon sliding flat surfaces the most desirable
lifting movements could not be so conveniently imparted to the toothed frames, as
they can by our present invention, where cams are and can be used of any desired
shape to act upon rounded or projecting surfaces (which are not directly connected
with and do not partake of the to and fro movement of the frames) or upon anti-
friction bowls as we prefer, by which we can obtain any desired up and down
movement combined with the to and fro movement suitable for propelling wool or
material in and delivering it from washing troughs.
In figs 1, 2 and 3 one mode of carrying out the third part of our invention is
illustrated.

page_text: a³ is an ordinary recess in the bottom of the trough, and a" is the outlet pipe
which has a valve to discharge the liquor in the usual manner.
Between the false bottom a¹ and bottom of the trough there are angle pieces alo
on each side extending from end to end.
The spaces along the two sides formed by these angled pieces communicate with
a space formed by an angle piece all across the end, and there is a narrow space
left between the bottom of the end angle piece and the bottom of the trough.
On each side there is a steam pipe with a nozzle n to come into the centre of a
cone nozzle, being an arrangement similar to that of a steam jet injector.
When the steam is turned on, a current is produced along each sido space, and
this gets into the end space and passes through the narrow space under the angle
piece all and then along the bottoin, and passes to the other end of the trough, the
current of liquid circulating as shown by the arrows in fig 3.
The steam is turned on while the outlet valve is open. The circulating current
produced by the stem jet or jets, stirs up and mixes the sediment with the liquid
and both the liquid and sediment so mixed are discharged through the outlet valve
while thus circulating.
In figs 4 and 5 another mode for carrying out the third part of our invention is
illustrated.
We in this modification use an angle piece a¹¹ at one end of the trough as shown
in figs 1, 2 and 3, but we cause the current to pass all in one direction in the space
between the false bottom and bottom of the trough by means of a pipe n¹ below
the bottom of the trough, and connected therewith at each end as shown.
A steam jet nozzle n is arranged in this pipe as shown in figs 4 and 5.
The current passes as shown by the arrows in fig 4.
We have now particularly described the nature of our invention and the modes
of carrying the same into effect and claim as our invention.
