PROVISIONAL SPECIFICATION.
Improvements in Slubbing, Intermediate, and Roving Frames
Employed in the Preparation of Fibrous Materials for
Spinning.
I, ROBERT TAYLOR, Junior, of Asa Lees and Company Limited, of Soho Iron
Works, Oldham, in the County of Lancaster, Engineer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in the "swing" or arrangement of links
which carry the gears by which motion is transmitted to the rising and falling
bobbin shaft from the driving shaft of a slubbing, intermediate or roving frame.
In carrying my improvements into effect I pivot an arm on the driving shaft and
another arm on the bobbin shaft and connect these two arms together by a link in
the manner set forth in the Specification to Letters Patent numbered 20639 and
granted to me on 27th November 1891. The studs by which the link is pivotel to
the arms support the two carrier wheels which gear with the toothed wheels on
their respective shafts. I connect the two arms together and control their
movements by a stud on one engaging a suitably shaped slot formed in the other,
the slot being so shaped as to prevent the possibility of any axial movement being
communicated to the bobbin shaft by the rise and fall of the lifting rail. I prefer
to use the arms and links in duplicate that is to say one set on each side of the
wheels.
As an alternative for the slots and studs I may fix a toothed wheel (or sector)
concentric with the driving shaft and another toothed wheel (or sector) concentric
with the bobbin shaft and of the same diameter as the toothed wheels on those
shafts and gear with these and with each other two wheels free to revolve on the
carrier wheel studs and having the same diameter as these wheels; or I may
make the guiding wheels or sectors without teeth and connect them together by
metal bands or chains so that a rolling motion would be given to them in practically
the same manner as if they were geared; in this last case the carrier wheels also
would be without teeth.
Dated this 9th day of March 1895.

COMPLETE SPECIFICATION.
Improvements in Slubbing, Intermediate, and Roving Frames
Employed in the Preparation of Fibrous Materials for
Spinning.
I, ROBERT TAYLOR, Junior, of Asa Lees and Company Limited, of Soho Iron
Works, Oldham, in the County of Lancaster, Engineer, 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 :-
My invention relates to improvements in the "swing" or arrangement of links
D

page_text: which carry the gears by which motion is transmitted to the rising and falling
bobbin shaft from the driving shaft of a slubbing, intermediate or roving frame.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying two sheets of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is a side elevation of the improved "swing
"with the wheels conveying
motion from the driving shaft to the bobbin shaft. Fig. 2 is a diagramatic view of
Fig. 1 showing the parts in their highest position.
Figs. 3 and 4 are side and sectional elevations respectively of one alternative
arrangement and Fig. 5 is a side elevation of another alternative arrangement
of my improved "swing."
Similar letters refer to similar parts throughout the several views.
In carrying my improvements into effect in the arrangement illustrated by
Figures 1 and 2, I pivot an arm a on the driving shaft b and another arm c on the
bobbin shaft d; and I connect these two arms together by a link e in the manner
set forth in the Specification to Letters Patent numbered 20639 and granted to me
on the 27th November 1891. The studs f1 by which the link e is pivoted to the
arms ac support the two carrier wheels g¹g of which the wheel gl gears with the
toothed wheel g which is mounted loosely on the driving shaft 6 and is driven by
the jack-in-box or differential motion as usual and the wheel 9³ gears with a
toothed wheel g fixed on the bobbin shaft d.
I connect the two arms a and c together and control their movements by a stud h
on one engaging a suitably shaped slot i formed in the other arm, the slot i being
so shaped as to prevent the possibility of any axial movement being communicated
to the bobbin shaft d by the rise and fall of the lifting rail. To determine the.
shape of the slot i it is necessary to prevent the wheels g g³ from rotating and to
observe and mark out the path of the stud h as the bobbin rail rises and falls.
I prefer to use the arms and links in duplicate that is to say one set on each side
of the wheels.
As an alternative for the slots and studs I may as illustrated in Figs. 3 and 4
fix a toothed wheel; (or sector) concentric with the driving shaft 6 on a bracket k
secured to the framing, this wheel or sector j being of the same diameter as the
toothed wheel g and in like manner I fix on the bracket on the lifting rail another
toothed wheel m (or sector) concentric with the bobbin shaft d and the same
diameter as the toothed wheel g³ and I gear the wheels or sectors j m together by
two toothed wheels n n' see Fig. 4, mounted loosely on the respective studs ff' on
which the toothed wheels g¹ g are also mounted.
As a further alternative illustrated by Figure 5, I may make the guiding wheels
or sectors jm without teeth and connect them together by metal bands o or chains
which pass in opposite directions over and under the carrier wheels n n' (in this
case without teeth) and are secured at each end to the peripheries of the two
wheels or sectors j m so that a rolling motion is given to the carrier wheels n n¹ in
practically the same manner as if they were geared.
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 1
claim is :-
In a swing consisting of three links or levers-
1. The combination and arrangement of parts for guiding and controlling the
movement of the swing and thereby preventing any axial movement being
imparted to the bobbin shaft by the rise and fall of the bobbin rail, substantially
as herein described with reference to Figs. 1 and 2.
2. The combination and arrangement of parts for and guiding controlling the
novement of the swing and thereby preventing any axial movement being
imparted to the bobbin shaft by the rise and fall of the bobbin rail, substantially
as herein described with reference to Figs. 3 and 4.
3. The combination and arrangement of parts for guiding and controlling the

page_text: movement of the swing and thereby preventing any axial movement being imparted
to the bobbin shaft by the rise and fall of the bobbin rail, substantially as herein
described with reference to Fig. 5.
