page_text: LETTERS PATENT to James Reynolds, of Belfast; in the County of
Antrim, Ireland, for the Invention of "IMPROVEMENTS IN ROVING OB
SLUBBING FRAMES, PARTLY APPLICABLE FOR IMPARTING MOTION IN OTHER
MACHINERY."
Sealed the 24th September 1872; and dated the 5th April 1872.
PROVISIONAL SPECIFICATION left by the said James Reynolds at
the Office of the Commissioners of Patents, with his Petition, on
the 5th April 1872.
I, JAMES REYNOLDS, of Belfast, in the County of Antrim, Ireland,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN ROVING OR SLUBBING FRAMES, PARTLY APPLICABLE FOR IMPARTING MOTION IN
OTHER MACHINERY," to be as follows:-

:-
My Invention consists in improvements in machinery for roving or
slubbing cotton, flax, tow, or other fibrous material to be made into
rove or sliver, part of which improvements is applicable for transmitting
motion in other machinery.

page_text: The first improvement relates to driving the bobbins and regulating
their take-up motion, and consists in a new construction of expanding
pulley and mechanism for adjusting the same, the pulley being wrought
by flat straps or bands, whereby perfect accuracy is ensured in regu-
lating the speed of the bobbins as they become filled with rove. These
pullies are intended to be employed in lieu of cones, discs, friction
pullies, or expanding pullies, with round cords, as used hitherto; and
my improved pullies may also be used for transmitting motion in other
machinery either at a fixed or variable diameter or circumference.
The pulley, which resembles a lantern. wheel in construction, consists of
4 discs, two at each side, with transverse rods to form the circumference
and determine the size of the pulley. The ends of these rods are
received in curved radial slots in the double discs running obliquely
towards the centre, the grooves in the double discs being inclined in
opposite directions so as to intersect one another, those in the two
innermost and two outermost discs being in the same direction.
pair of discs are keyed to a shaft and the other to a sleeve on said shaft,
having an inclined slot, on which works a feather on another sleeve,
fitted on the shaft in such a manner as to admit of its being moved to
and fro along the shaft without turning, whereby the other sleeve and
with it the one pair of discs are caused to partially rotate, causing the
point of intersection of the slots on the double discs and consequently
the transverse bars to approach or recede from the centre, and so
contract or expand the pulley. The sliding sleeve is moved by a plate
having a curved slot in which works a pin on a collar connected to said
sleeve in which the shaft is free to revolve.

My Invention relates, 2ndly, to a contrivance for reversing the traverse
or up-and-down, motion of the bobbin lifter in an instantaneous
manner, whereby stretching or straining the rove or sliver is avoided,
and perfect uniformity in the building or warping of it on the bobbins.

The contrivance of my Invention is intended to replace the mangle
wheels commonly used for the purpose, these being slow in reversing
the bobbin lifter. On the bobbin lifter shaft is keyed a face plate
provided with tappets made adjustable to accommodate the bobbin lifter
traverse, which tappets come alternately into contact with part of a
sliding arm or lever mounted on the bobbin lifter shaft which passes
through a long slot in the lever to admit of the latter traversing the

incline which is caused by the traverse of the lever to work over
corresponding inclines on the movable bearing of a pinion which by
the pressure of the lever is shifted to and fro into gear, first with one
wheel and then with another, in connection with the bobbin lifter shaft,
thereby reversing the motion of the bobbin lifter each time.

The Invention relates, 3rdly, to a method of conveying motion to
the bobbin and spindle shafts at two or more different points by so
arranging the general construction of the frame as to admit of this
being effected in order to lessen the torsion of these shafts, the motion
being transmitted by gearing of different pitches to prevent back' laslı
or tugging in the bobbins, and for imparting a more uniform speed to
the spindles.

NOW KNOW YE, that I, the said James Reynolds, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the two Sheets of
Drawings hereunto annexed, and to the letters and figures marked
thereon (that is to say) :-
:―
My Invention consists in improvements in machinery for roving or
slubbing cotton, flax, tow, or other fibrous material to be made into rove
or sliver, part of which improvements is applicable for transmitting
motion in other machinery.
The first improvement relates to driving the bobbins and regulating
their take-up motion, and consists in a new construction of expanding
pulley and mechanism for adjusting the same, the pulley being of such
construction that it may be wrought by flat straps or bands, whereby
perfect accuracy is ensured in regulating the speed of the bobbins as
they become filled with rove. These pullies are intended to be employed
in lieu of cones, discs, friction pullies, or expanding pullies, with round
cords, as used hitherto; and my improved pullies may also be used for
transmitting motion in other machinery either at a fixed or variable
diameter or circumference. The pulley resembles a lantern wheel in
construction, and consists of four discs, two at each side, with transverse
rods to form the circumference and determine the size of the pulley.
The ends of these rods are received in curved slots in the double discs
running obliquely towards the centre, the grooves in the double discs
being inclined in opposite directions so as to intersect one another,
those in the two innermost and two outermost discs being in the same
direction. One pair of discs are keyed to a shaft and the other to a
sleeve on said shaft, having an inclined slot, in which works a feather on
another sleeve, fitted on the shaft in such a manner as to admit of its
being moved to and fro along the shaft without turning, whereby the
other sleeve and with it the one pair of discs are caused to partially
rotate, causing. the point of intersection of the slots on the double discs
and consequently the transverse bars to approach or recede from the
centre, and so contract or expand the pulley. The sliding sleeve is
moved by a plate having a curved slot, in which works a pin on a collar
connected to said sleeve in which the shaft is free to revolve.

page_text: My invention relates, 2ndly, to a contrivance for reversing the traverse
or up-and-down motion of the bobbin lifter in an instantaneous manner,
whereby stretching or straining the rove or sliver is avoided, and perfect
uniformity in the building or warping of it on the bobbin is ensured.
The contrivance of my Invention is intended to replace the mangle
wheels commonly used for the purpose, these being slow in reversing the
bobbin lifter. On the bobbin lifter shaft is keyed a face plate provided
with tappets made adjustable to accommodate the bobbin lifter traverse,
which tappets come alternately into contact with part of a sliding arm or
lever mounted on the bobbin lifter shaft which passes through a long
slot in the lever to admit of the latter traversing the shaft. The lever
is provided with a wedge-shaped projection or double incline, which is
caused by the traverse of the lever to work over corresponding inclines
on the movable bearing of a pinion, which by the pressure of the lever
is shifted to and fro into gear, first with one wheel and then with another,
in connection with the bobbin lifter shaft, thereby reversing the motion
of the bobbin lifter each time.
The Invention relates, 3rdly, to a method of conveying motion to the
bobbin and spindle shafts at two or more different points in order to
drive them more uniformly and lessen the torsion to which they are
subject when driven from one end, and the motion may be transmitted
by gearing of different pitches to avoid back lash and prevent the bobbins
tugging and straining the rove or sliver, and for imparting a more

page_text: intersection of the slots of one disc a with those of the other disc b
recede from the centre, when discs a or 6 are partially rotated.. The
outer pair of discs a, a, are keyed on a sleeve e on shaft f, the inner
pair b, b, being keyed to the shaft by pins 9, 9, passing through slots in
sleeve e to allow of the latter with discs a, a, being partially rotated
independently of discs b, b. These pins g also serve to keep the sleeve
in its place on the shaft. h, Figure 3, is the inclined or spiral slot in
the sleeve e, in which works a pin i on a second sleeve j keyed on shaft ƒ,
with a groove and feather connection to allow it to be slid on the shaft
in or out of sleeve e for turning the same together with discs a, a, in one
or other direction for increasing or decreasing the diameter of the pulley.
This is effected by means of a collar or socket / fitted on sliding sleeve j,.
so that the latter is free to revolve therein with shaft f, and provided with
a pin working in a curved slot in a plate . The expanding pulley
shaft is mounted in bearings at the ends of arms m (see Figure 4),
which compose a frame carried by pivots m¹ mounted in bearings in the
framework A of the machine, so that shaft may be moved in an arc of
a circle, of which arms m are the radius to admit of the band by which
the pulley is driven, being kept at an equal tension notwithstanding the
varying diameter of the pulley. To the said frame is attached a counter-
balance weighted lever B, which tends to raise the pulley, and is
supported by a chain C connected to a sheave D mounted in the
framing A, and geared with a ratchet wheel E by wheels D', E¹. The
ratchet wheel E is controlled by two weighted latch levers F, F, which
hold it alternately, and are raised out of the teeth by a pin G which
projects from the end of the bobbin lifter and strikes the latches F,
thereby allowing the ratchet wheel to revolve to the extent of half a
tooth at each up-and-down motion of the bobbin lifter. By this means,
as the diameter of the bobbins is gradually increased by fresh layers of.
rove, the chain is permitted to uncoil from sheave D, and the weighted
lever B is gradually lowered, and the expanding pulley raised at the
same time that its working diameter is increased by the pin k¹ on
collar k, pressing against the slot in plate lª, which is so hinged, or
suspended from the table of the frame A (see Figure 3) that it is free to
swing and accommodate itself to the are described by the shaft of the
expanding pulley. In this manner the speed of the bobbins is so varied
as to cause them to take up the rove uniformly, and the ratchet or
index E above mentioned may be changed if required to suit the class of
rove to be produced.

page_text: Figure 5 represents a side view of an arrangement for working two of
these expanding pullies together when required, and Figure 6 a front
view of the same. The same reference letters indicate similar parts to
those in the preceding Figures.
His a lever mounted on a fulcrum I, and having two equal arms
whose extremities H¹ are forked, and embrace the sliding parts of the
pullies respectively, and are connected thereto as shown. D is the
sheave geared to the ratchet E by wheels D', E', and having a chain C
connected, to which is attached a weight to turn the ratchet wheel.
The latter is provided with a cam K, against which bears a friction
roller on one arm of lever H, so that as the ratchet wheel is allowed to
turn by the latches F, F, being alternately freed by the bobbin lifter, as
before described, the tappet K will force back the arm of lever H, and
draw out the sleevej of the lower pulley, which is thereby contracteḍ
by the action of the devices previously described, at the same time that the
other end of lever H and sleeve ; of the upper pulley is pushed inwards,
and the pulley is consequently expanded in the same proportion, both
pulleys being constructed and operated as before described in reference
to the single pulley, except that they are not mounted in a rocking
frame..
Figure 7 is a detached view of the arrangement for reversing the
bobbin lifter, which is also shown applied in Figure 4 together with, its
connections. M is a lever mounted on the bobbin lifter shaft N which
passes through a slot n formed by a bracket M¹ bolted to the lever and
having a projecting pin o. O is a face plate keyed on the shaft N, and
provided with an adjustable tappet or tappets O¹, the faces of which strike
alternately against pin o as the shaft N rotates in one or other direction
to raise and lower the bobbin lifter, thereby causing lever M to move
longitudinally to and fro, to permit of which the slot n is provided. The
extremity M² of the lever is weighted, and rests on a movable bearing
p of a pinion p mounted in a box or frame P fixed to the framing A of
the machine; r is a wedge-shaped projection on the under side of lever
M which rests on the bearing/p, the top of which has also a double
incline, as shown, and moves the bearing to and fro each time the lever
M is moved by the tappeto striking pin o.. The, movement of the
sliding bearing p is limited by the two fixed parts 9, 9, and the pinion
p' is mounted on the end of a shaft supported in said bearing, to, which.
shaft power is applied from: the main shaft Z to impart alternate rotary

page_text: motion to the bobbin lifter shaft; R, R', are two intermediate spur
wheels geared together, wheel R' being also geared to the bobbin
lifter shaft N, and with which wheels pinion p¹ is put into gear alter-
nately by the shifting of bearing p. Thus, supposing face plate O
to revolve in the direction of the arrow, and the parts to be in the
position shown in Figure 4, tappet O' will strike pin o and move lever
M, causing wedger to rise up the incline on p until its point passes
over the top. of the same when the weight M³ will cause it to descend
on the other side and force along the bearing p until it comes into
contact with q', thereby throwing pinion p¹ out of gear with R and
into gear with R', and consequently reversing the direction of motion of
the bobbin lifter shaft N and its connections until the other end of
tappet O¹ strikes pin o and moves the lever M in the other direction,
when the same movements are repeated in the opposite direction and
the bobbin lifter is again reversed.
Figure 8 shows the way in which motion is imparted to the bobbin
shafts at two or more points. S is the differential wheel commonly
used from which motion is transmitted at more than one point to the
bobbin shaft T by bevel gear and an intermediate shaft s as shown; t is
the bobbin lifter. The two shafts T, T', carry bevel pinions, and drive the
bobbins through pinions u, u', which support. and impart motion to the
bobbins as usual. The other bobbin shaft T is driven at two or moro
points from shaft T. by pinions v, v¹, of the same or different pitches of
teeth so that these shafts may be driven more uniformly than is the
case at present. When of the same pitch it is only necessary that the
two sets of pinions should be so keyed on their shafts that the teeth of
one set are longitudinally opposite the spaces between the teeth of the
other set.
Figure 9 shows a front view of the arrangement for conveying motion
to the spindle shafts by gearing of the same or different pitches at two
or more points, the object being to distribute the power applied equally
along the said shaft or shafts and thereby avoid the twisting or jerking
consequent on driving the shafts at one end only, which renders the
motion of the spindles irregular and causes them to tug and strain the
rove or sliver. In Figure 4 the arrangement is shown applied to the
machine. The bevel wheels U, U¹, are keyed to the main shaft Z,
and placed at such a distance apart that they divide equally the driving
power. Y is the spindle shaft, to which motion is imparted from wheels

page_text: U, U', through the bevil wheels V, V', keyed on intermediate shafts Y³,
which also carry bevel wheels W, W', gearing with wheels X, X¹, on
the spindle shaft. Wheel U and the gearing which it drives may be
of the same or of a different pitch of teeth to that of wheel U¹ and
the other set of gearing.
Having described the nature of my Invention and in what manner
the same is to be performed, I declare that what I claim as my
Invention, to be protected by the herein-before in part recited Letters
Patent is:-
1st. The improved construction of expanding pulley arranged and
operating substantially as herein-before described and shown in Figures
1, 2, 3, and 4 of the Drawings for transmitting motion in roving or
slubbing frames and other machinery in which varying speed is
required.
2ndly. The mechanism, arranged, applied, and operating substantially
as herein-before described and illustrated in Figures 4 and 5 of the

4thly. Imparting motion in such frames to the spindle shafts at two
or more points in the latter by gearing of the same or different pitches
arranged and applied substantially as described and shown in Figures
4 and 9.
