Improvements in Slubbing, Intermediate, and Roving Frames
employed in the Preparation of Fibrous Materials for Spinning.
I, JAMES LUCAS, of Globe Works, Accrington, in the County of Lancaster
Machine Fitter, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of slubbing, inter-
mediate and roving frames used in the preparation of cotton and other fibrous
substances for spinning, the object being to prevent undue strain, or tension, and
consequently stretching of the rove or thread at the time the bobbins are changing
from a rising to a falling motion or vice versa.
Heretofore when bobbins have been caused to revolve at a decreasing speed
according as the diameter of the rove or thread thereon increased, such change
took place shortly after or later than the change in the direction of motion of the
lifting rail owing to the ordinary radial arm connected with such lifting rail having
to lift or overcome the tumbler weights or springs consequently the bobbins have
revolved for a short time (say one revolution) at the same speed after the direction
of motion of the lift has changed and the rove or thread was stretched or strained
at such time.
My invention consists in the employment of mechanism for lifting the tumbler
weights or overcoming the tumbler springs, and removing strain from the radial
arm, direct from and by the lifting shaft, or top rail so as to cause the direction of
inotion of the lifter rail and speed of revolution of the bobbins to change
simultaneously so obviating the above defect.
According to my said invention for purpose aforesaid I employ a separate or
independent swing catch or quadrant actuated by a worm fixed on the lifting
shaft; or a quadrant lever actuated by a wheel fixed on the lifting shaft, or a com-
bination of lever and spur rack actuated by a wheel fixed on the lifting shaft, or by
lifting chains or ropes with blocks or pulleys fixed to and actuated by the lifting
shaft according to the class of frame or machine to which the improvements are to
be employed.

Improvements in Slubbing, Intermediate, and Roving Frames
employed in the Preparation of Fibrous Materials for Spinning.
I JAMES LUCAS of Globe Works, Accrington in the County of Lancaster,
Machine Fitter, 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 :-
This invention relates to improvements in the construction of slubbing, inter-
mediate, and roving frames used in the preparation of cotton and other fibrous
substances for spinning the object being to prevent undue strain, or tension, and
consequently stretching of the rove or thread at the time the bobbins are changing
from a rising to a falling motion, or vice versa.
Heretofore when bobbins have been caused to revolve at a decreasing speed
according as the diameter of the rove or thread thereon increased, such change

page_text: took place shortly after or later than the change in the direction of motion of the
lifting rail owing to the ordinary radial arm connected with such lifting rail
having to lift or overcome the tumbler weights, or springs consequently the
bobbins have revolved for a short time (say one revolution) at the same speed after
the direction of motion of the lift has changed, and the rove or thread was
stretched or strained at such time.
My invention consists in the employment of mechanism for lifting the tumbler
weights, or overcoming the tumbler springs, and removing strain from the radial
arm direct from and by the lifting shaft or top rail so as to cause the direction of
motion of the lifter rail and speed of revolution of the bobbins to change
simultaneously so obviating the above defect.
According to my said invention for purpose aforesaid I employ a separate or
independent swing catch or quadrant actuated by a worm fixed on the lifting
shaft or a quadrant lever actuated by a wheel fixed on the lifting shaft, or a com-
bination of lever and spur rack actuated by a wheel fixed on the lifting shaft, or
by an arrangement of levers actuated by the top or bobbin building rail, or by
levers actuated by eccentrics or cams fixed on the lifting shaft, or by lifting
chains, or ropes with blocks or pulleys fixed to and actuated by the lifting shaft
according to the class of frame or machine to which the improvements are to be
employed.
Such being the nature and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings
in which:-
Fig. 1. is a front elevation of suitable apparatus applied to a slubbing, inter-
mediate, or roving frame to ensure the simultaneous change of speed of the bobbins,
and change of direction of motion of the lifter rail.
Fig. 2. is a sectional end elevation of Fig. 1.
Fig. 3. is a sectional elevation of part of Fig. 2.
Fig. 4. is an elevation of apparatus operated from the builder rail.
Fig. 5. is an end view of Fig. 4.
The several figs. on Sheet 3 are details drawn detached in order to shew their
construction more clearly.
According to this invention at 1 is the ratchet wheel which receives its motion
from the diag weight as ordinary. The shaft 2 is carried on the bosses 3. 3. shown
in detail by Fig. 3 Sheet 2 and carries on its end the spur wheel 4 gearing with
the rack 5 on the radial arm 6. The radial arm 6 works through holes in the lug
or bracket 7 cast to or forming part of the rocking bracket 8 which has two
lugs 9. 9 cast to it. In each of the lugs 9. 9. is an adjustable set screw 10 and 11
and when the lifter rail 12 begins say its downward motion the end of the radial
arm 6 which is carried in the slot 13 is also carried down with said lifter rail and
the bracket 8 is slightly turned on its axis which is the shaft 2. and the adjustable
set screw 11 will come in contact with the end or finger 14 and depress the latter
so raising its catch end 15 until the latter is clear of the holding notch 16 in the
bracket 17 free to rock on its axis which is the shaft 2. The lower end of the
bracket 17 moves in a radial slot 17° and carries a cross piece 18 the ends of which
come in contact with the vertical rocking arms 19. 19 carried on studs 20. 20.
the upper ends of the rocking arins 19. 19. are holding catches 21, 21, which
engage with the teeth of the ratchet wheel 1. The arms 19. 19 are drawn towards
each other and the catches 21, 21 held in contact with the ratchet wheel 1 by
means of the spiral spring 22. When the bracket 17 rocks on its axis 2 as above
described one end of the cross piece 18 forces the catch 21 out of the ratchet
wheel 1 and the latter is free to turn for a space of part of one tooth or until the
opposite catch 21 by means of the spiral spring 22 catches into one of the spaces
between the teeth of the ratchet wheel 1 and arrests its further movement. On
the bracket 17 are two wings or lugs 24. 24 through holes or slots in which are-
passed the rods 25. 25 at the lower end of which are suspended the weights 26. 26
and as soon as the catch 15 releases the notch 16 the weight 26 will turn the
At

page_text: bracket 17 on its axis and the lower end 27 to which the upper end of the ordinary
reversing lever 27* is connected is operated and the direction of motion of the
top rail is reversed.
On the lifter shaft 28 is a worm 29 driving the worm wheel 30 loose on its
carrying stud and in the boss of said wheel 30 is formed a clutch which engages.
with a clutch formed on the boss of the quadrant lever 31 free to turn on its
axis.32. The outer ends 33 of the quadrant lever 31 pass underneath the
adjustable hooks 34 formed in the rods 25 which carry the weights 26. 26. and the
quadrant will raise the weights at the required time and as arranged by the clutch.
which by cutting away more or less a longer or shorter dwell can be obtained
before the quadrant is operated upon by the clutch of the worm wheel and by
varying the distance or space between the clutches the apparatus can be regulated
to suit various length of bobbins.
A spiral spring 35 is employed to keep the catches 15. 15 in contact with the
bracket 17.
At 12 is the builder rail to which is attached the bracket 13. the parts 25, 26,
31, 32, 34, are like parts to those shewn in Figs. 1 and 2 Sheet 1. The lever 36.
being employed instead of the wheel 30. (Figs. 1 and 2) the clutch being divided
one part thereof being on the boss 32 the other part of said clutch being attached
to the fulcrum end of the lever 36. The operating of the lever 36 is from the
movement of the builder rail 12 through the rod 37 and adjustable stop pieces 37. 38
which raise or lower the lever 35 and thereby the weights 26 to allow the tumbler
bracket 17 to move simultaneously with the builder rail.
It will be seen as above explained that the lifter shaft is available (by any of
the several equivalent means set forth) for effecting the requisite adjustment of and
rotation of the bobbin to the movements of the lifter rail.
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 general arrangement construction and combination of apparatus illus-.
trated by Figs. 1. 2 and 3 for purpose herein set forth.
2. The apparatus herein described and illustrated by Figs. 4. and 5 for purpose-
set forth.
3. Mechanism such as herein described whereby the motion of the lifter rail and
the speed of rotation of the bobbins is changed and adjusted simultaneously so as to.
avoid undue strain or tension on the rove or thread.
