Preparing Machines.
I, EDWARD BUCKLEY, of the firm of Taylor Lang & Co. Limited, Castle Iron Works,
Stalybridge in the County of Chester, Machine Makers, do hereby declare the nature
of the said invention, to bo as follows:-
The ordinary mechanism for equalizing the feed of fibrous materials to preparing
machines consists of a roller, and a series of levers with a short and long arm, side by
side, and the fibre passes between the short arms of the levers and the roller, and
causes the long arms of the levers to rise and fall as the thickness of the fibre fed
varies.
On each long arm of each lever, a bar is suspended having inclined or wedge shaped
sides and these bars are termed " pendents and they act upon rollers or pulleys
placed to come between the inclines upon the pendents, and one pendent thus acts
upon another and they all act together to show the general average thickness of the
sheet or lap of fibre being fed, and operate upon well known mechanism to vary the
speed of the roller accordingly as the general average thickness of the fibre or lap or
laps changes, that is, to decrease the speed, if the general average thickness increases,
and vice versa, if the general average thickness decreases.
The bowls or rollers between the inclines of the pendents when one, two or more are
used, as hitherto, roll against the inclines and each other, and upon guide ways in
horizontal guide bars, and when three pulleys are used on the same axis, the ends of
the axis rolls on horizontal guide ways, and two of the bowls come upon one side of
the incline of one pendent and one against a rib or incline on the other side of another
pendent.
One part of my improvements consists in using three bowls on the same axis, and a
pair of these three bowls on the same axis between each pair of pendents. The two
outside bowls on each axis run on the horizontal guide ways and close against each
other, or they are kept separate by links between their axes.

page_text: The middle bowl on each axis is or may be less in diameter than the end bowls so
that the middle bowls of each pair do not come in contact with each other as the
outside bowls do or may do and are separately free to rotate on, their respective axis
and against the inclines upon the pendents.
Another improvement consists in making the inclined end or wedge of each pendent
separate from its stem and bending the stem to come on one side and carry the lower
end of the pendent, or the stem and inclined end or wedge of the pendent bent as
above explained is or may be formed in one piece.
When constructed and arranged as last described the upper ends of the inclines or
wedges are or can be covered to provent fibre from accumulating upon them to
obstruct their free action.
Another part of my invention consists in dispensing with the inclines or wedges on
the pendents and mounting antifriction bowls upon them instead, these bowls acting
upon inclines or wedges on a stem (having the form of spears) suspended from a stud,
there being one such spear pendent suspended between each pair of pendents with
bowls.
The studs for the spear headed pendents are secured in a bar extending across the
machine or on a cover plate to protect the mechanism from fibre.
The pendents with bowls and spear heads swing and are allowed to move freely
between horizontal guide bars.
The lower ends of the bowl pendents, and spear ended pendents are or may be bent
or arranged so as to be covered or protected from fibre, as hereinbefore explained with
respect to pendents carrying or having formed upon them inclined or wedged shaped
ends.

Improvements in or Applicable to Mechanism for Equalizing the
Feed of Fibrous Materials to Scutchers, Openers, and other
Preparing Machines.
I EDWARD BUCKLEY of the firm of Taylor Lang & Co. Limited, Castle Iron Works,
Stalybridge in the County of Chester, Machine Makers, 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 :-
The ordinary mechanism for equalizing the feed of fibrous materials to preparing
machines consists of a roller, and a series of levers with a short and long arm, side by
side, and the fibre passes between the short arms of the levers and the roller and
causes the long arms of the levers to rise and fall as the thickness of the fibre fed
varies.
On each long arm of each lever, a bar is suspended having inclined or wedge shaped
sides and these bars are termed "pendents" and they act upon rollers or pulleys placed
to come between the inclines upon the pendents, and one pendent thus acts upon
another and they all act together to show the general average thickness of the sheet or
lap of fibre being fed, and operate upon well known mechanism to vary the speed of
the roller accordingly as the general average thickness of the fibre or lap or laps
changes, that is to decrease the speed, if the general average thickness increases, and
vice versa, if the general average thickness decreases.
The bowls or rollers between the inclines of the pendents when one, two or more
are used, as hitherto roll against the inclines and each other and upon guide ways in
horizontal guide bars, and when three pulleys are used on the same axis, the ends of
the axis rolls on horizontal guide ways, and two of the bowls come upon one side of
the incline of one pendent and one against a rib or incline on the other side of another
pendent.
One part of my improvements consists in using three bowls on the same axis, and a
pair of these three bowls on the same axis between each pair of pendents. The two
outside bowls on each axis run on the horizontal guide ways and close against each
other or they are kept separate by links between their axes.
The middle bowl on each axis is or may be less in diameter than the end bowls so
that the middle bowls of cach pair do not come in contact with each other as the
outside bowls do or may do and are separately free to rotate on their respective axis
and against the inclines upon the pendents.
Another improvement consists in making the inclined end or wedge of each pendent
separate from its stem and bending the stem to come on one side and carry the lower
end of the pendent, or the stem and inclined end or wedge of the pendent bent as
above explained is or may be formed in one piece.
When constructed and arranged as last described the upper ends of the inclines or
wedges are or can be covered to prevent fibre from accumulating upon them to
obstruct their free action.

page_text: Another part of my invention consists in dispensing with the inclines or wedges on
the pendents and mounting antifriction bowls upon them instead-these bowls acting
upon inclines or wedges on a stem (having the form of spears) suspended from a stud
there being one such spear pendent suspended between each pair of pendents with
bowls.
The studs for the spear headed pendents are secured in a bar extending across the
machine or on a cover plate to protect the mechanism from fibre.
The pendents with bowls and spear heads swing and are allowed to move freely
between horizontal guide bars.
The lower ends of the bowl pendents, and spear ended pendents are or may be bent
or arranged so as to be covered or protected from fibre, as hereinbefore explained
with respect to pendents carrying or having formed upon them inclined or wedged
shaped ends.
Fig. 1 is a sectional elevation of parts in the lengthway of the machine and fig. 2
is a front elevation of the same.
Fig. 3 is a plan section of parts detached, on an enlarged scale.
a is part of the side framing of a scutcher or other like opening and preparing
machine.
bis part of a feeding apron or lattice, which works round a roller b₁ passing across
the machine at one end, is a roller extending across the machine for feeding forward
the fibrous materials which passes under the roller and between it and the upper
surface of the short arm of a lever c resting upon a fulcrum shaft or bar c¹
extending across the machine.
There are a series of these levers c side by side, across the machine as shown by
fig. 2, and the long arm of each lever c has a wedge ended bar d suspended from it
which are termed pendents.
с
The ordinary pendents are straight bars, and come straight down from the end of
the levere between two guiding bars e carried on the framing.
One of my improvements consists in employing two rollers to come between each
pendent & the periphery of one roller touching the inclined surface d' of one pendent,
and that of the other roller the inclined surface of the adjoining pendent.
The peripheres of each pair of rollers are kept from touching as the pivots of each
roller enter boles in the axes of narrow rollers 1 of larger diameter than the middle
rollers and the peripheries of these narrow rollers f¹ of each pair are in contact and
run upon ledges formed in the guiding bars e (see figs. 2 and 3).
According to another modification of my invention tho three rollers f¹, fand "aro
or may be of the same diameter, and there is a link at each end of the middle
roller in the holes in which the pivots of the middle rollor can freely rotate these
links acting to keep the two pairs of three rollers f³, f and f¹ apart as shown in
fig. 3, where e represents the guiding bars, and d the plan section of the pendents.
Another improvement consists in bending each pendent d as shown in figs. 1 and 2
to pass on the outside of the guiding bars e, the lower end of the pendent being bent
at a right angle to come under the centre of the space between the guiding bars e
upon which bent end the wedge d is placed and is or may be secured thereto by a set
screw as shown in fig. 1.
Above the wedges d' of the pendents when so arranged, a cover g is placed, of the
shape shown in fig. 1, which cover rests at its lower ends on ledges formed on the
guide bars e as shown.
Thus arranged loose fibre is prevented from accumulating between the wedges d' of
the pendents and the rollers f.
In fig. 2 the front or outside guiding bar e is supposed to be removed to show
rollers more clearly, and the cover g is shown in section.
In other respects the mechanism is arranged and acts in the ordinary manner.
Figs. 4 and 5 are views corresponding respectively to figs. 1 and 2 but illustrate
another modification of my invention.
In fig. 5 the front guide bar (e) is supposed to be removed.

page_text: The parts marked a b, b¹ b c and e¹ in these figures are the same as those having
the same letters of reference shown in figs. 1 and 2.
The pendents d in this modification are straight bars, suspended from the levers ▸
and passing freely between the guide bars e.
The lower end of each pendent has two studs secured in it each stud having a
bowl d' upon it.
at
The pendents & come between wedge ended rods h suspended freely from a stud
secured in a plato 2 attached to the framing.
One bowl on one pendent d coines against the edge of the wedge h³ on one side,
and the other bowl against the edge of the adjoining wedge h³.
One bowl on the pendent at one side works against a bracket with an incline
face secured to the framing.
It will be seen that a movement up or down of say the pendent d nearest the fixed
bracket h will cause all the other pendents & and wedge ended rods h to move
sideways in the lengthway of the guide bars e and the up and down movements
of the other pendents d will act so as to be transmitted to the ordinary mechanism
for varying the speed of the feed roller *.
The connecting mechanism between the last pendent (say that marked d×) on the
right of figs. 2 and 5 or the last wedge ended rod h (say that marked h*) on the right
of fig. 5 (if it is on the right of the last pendent d) and mechanism for changing the
speed of the roller 62 as the fibrous material varies in thickness is or may be the same
as the ordinary connecting mechanism.
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. The employment of two rollers (f) between the wedges (d') of the pendents,
each roller (f) having two narrow rollers (¹) one on each pivot, and with or without
links or connections (f) between the rollers f, substantially as and for the purpose
hereinbefore described and illustrated by figs. 1, 2 and 3 of the drawings.
2. The construction of the pendents (d) with the wedge end (d¹) arranged to be
covered by a plate (g) substantially as and for the purpose hereinbefore described and
illustrated by figs. 1 and 2 of the drawings.
3. The combination of pendents (d) with bowls (d) with suspended wedge ended
rods (h) substantially as and for the purpose herein before described and illustrated by
figs. 4 and 5 of the drawings.
