This Invention, which relates to improvements in frames for spinning, doubling,
twisting and roving jute, flax, hemp, cotton worsted and other fibrous substances,
has for its object to dispense with the ordinary manual operations of "shifting" or
doffing" the bobbins and of "piecing" the yarn. For these ends, the pins or studs
on which the bobbins are carried are fixed at opposite sides of a shaft mounted in
brackets capable of moving upwards and downwards on or in slides attached to,
or forming part of the frame. The bobbin-board is also mounted on slides and rests
upon the aforesaid brackets or their equivalents during the ordinary traverse. The
sliding brackets are supported by adjustable links connected to a series of counter-
weighted levers fastened on a shaft situated lengthwise with the frame, and this shaft
during the running of the frame is actuated upwards and downwards, that is to say,
in its ordinary traverse, by a heart-cam and chains or the equivalent thereof.
Attached either to the bobbin-board or other suitable part of the frame, or connection
of the frame are knives or equivalent cutters, combined with holding devices, the
former of which cut the yarn after the full bobbins have been doffed, and the latter
hold the yarns, as the frame starts to wind them on to a fresh set or empty set of
bobbins. The lower set of pins or studs previously to the stopping of the frame has
been provided with another or empty set of bobbins.
-
The bobbin-board used in connection with these improvements is of such con-
struction that it admits of the pins or studs in their revolution placing the empty
bobbins partly above the bobbin-board and this bobbin-board has a traverse slightly
in excess of the ordinary traverse when the frame is running.
The operation of these improvements is as follows:-So soon as a set of bobbins is
filled with yarn the frame is stopped, and near to the lower limit of the ordinary

page_text: traverse, then the heart-cam motion is disengaged from the counterweighted levers,
and they together with the shafts carrying the bobbin pins or studs, are moved
through an additional traverse sufficient to withdraw the said studs or pins out from the
filled bobbins which remain standing on the bobbin-board.
At this stage the shaft carrying the bobbin studs or pins is rotated through an arc
of a circle, that is to say, so that the said studs or pins reach a horizontal position,
when the counterweighted levers carrying the said shaft and pins or studs are returned
to the lower limit of the ordinary traverse and become connected with the heart-cam
mechanism. At this position the shaft and bobbin pins or studs are turned through
another arc, the effect of which is to bring the pins or studs carrying the empty set of
bobbins vertically uppermost, and by this movement and contact to displace the filled
bobbins standing on the bobbin-board, causing them to fall over the front of the bobbin-
board and cutting devices, which are operated so as to cut the several yarns, whilst the
holding devices retain them for being laid on the set of empty bobbins.
It is to be understood that the shaft carrying the bobbin studs or pins, as well as
the bobbin-board itself may both be supported and traversed by the chains and shifter
rods ordinarily employed in such frames.
It is further to be understood that these improvements are specially adapted for use
in connection with the flyers rotating independently of spindles described in the
specifications of the said William Robert Laing respectively numbered 3820 and 8111
both of 1887.

Improvements in Frames for Spinning, Doubling, Twisting, or
Roving Jute, Flax, Hemp, Cotton, Worsted, or other Fibrous
Substances.
I, WILLIAM ROBERT LAING of Stobwell Works, 10 Panmure Street, Dundee, in the
County of Forfar, North Britain, Spinner and Manufacturer 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, which relates to improvements in frames for spinning, doubling,
twisting and roving jute, flax, hemp, cotton, worsted and other fibrous substances, has
for its object to dispense with the ordinary manual operations of shifting" or
doffing" the bobbins and of "piecing" the yarn. For these ends, the pins or studs
on which the bobbins are carried are fixed on a shaft mounted in brackets capable
of moving upwards and downwards on or in slides attached to, or forming part of the
frame. The bobbin-board is also mounted on slides and rests upon the aforesaid
brackets or their equivalents during the ordinary traverse. The sliding brackets aro
supported by adjustable links connected to a series of counterweighted levers fastened
on a shaft situated lengthwise with the frame, and this shaft during the moving of
the frame is actuated upwards and downwards, that is to say, in its ordinary traverse,
by a heart-cam, and chains or the equivalent thercof. Attached either to the bobbin-
board or other suitable part of the frame, or connection of the frame are knives or
equivalent cutters, combined with holding devices, the former of which cut the yarn
after the full bobbins have been doffed, and the latter hold the yarns, as the frame
starts to wind them on to a fresh set or empty set of bobbins. The lower set of pins
or studs previously to the stopping of the frame has been provided with another or
empty set of bobbins.
The bobbin-board used in connection with these improvements is of such construction
that it admits of the pins or studs in their revolution placing the empty bobbins
partly above the bobbin-board and this bobbin-board has a traverse slightly in excess
of the ordinary traverse when the frame is running.
The operation of these improvements is as follows. So soon as a set of bobbins is
filled with yarn the frame is stopped, and near to the lower limit of the ordinary
traverse, then the heart-cam motion is disengaged from the counterweight levers, and
they, together with the shafts carrying the bobbin pins or studs, are moved through
an additional traverse sufficient to withdraw the said studs or pins out from the
filled bobbins which remain standing on the bobbin-board.
At this stage the shaft carrying the bobbin studs or pins is rotated through an
arc of a circle, that is to say, so that the said studs or pins reach a horizontal
position, when the counterweighted levers carrying the said shaft and pins or studs
are returned to the lower limit of the ordinary traverse and become connected with
the heart-cam mechanism. At this position the shaft and bobbin pins or studs are

page_text: turned through another arc, the effect of which is to bring the pins or studs carrying
the empty set of bobbins vertically uppermost, and by this movement and contact to
displace the filled bobbins standing on the bobbin-board, causing them to fall over the
front of the bobbin-board and cutting devices, which are operated .so as to cut the
several yarns, whilst the holding devices retain them for being laid on the set of
empty bobbins.
It is to be understood that the shaft carrying the bobbin-studs or pins, as well
as the bobbin-board itself may both be supported and traversed by the chains and
shifter rods ordinarily employed in such frames.
It is further to be understood that these improvements are specially adapted for use
in connection with the flyers rotating independently of spindles described in the
specifications of the said William Robert Laing respectively numbered 3820 and
8111 both of 1887.
In order that my Invention may be properly understood and readily carried into
effect, I have hereunto appended four explanatory sheets of drawings in the
several Figures of which corresponding parts are marked with the same letters of
reference.
Figure 1, is a front elevation of part of a spinning frame shewing my Invention
applied thereto.
Figure 2, is a transverse vertical section of part of such frame shewing my said
improvements drawn to a larger scale than in Figure 1.
Figure 3, is an end view of the feed mechanism for giving the necessary traverse
to the frame.
Figure 4, is a part plan of the bobbin-board and Figures 5 and 6 are respectively
elevations of detached parts of the mechanism constructed in accordance with and
constituting part of my invention.
Figures 7 and 8, are respectively transverse vertical sections of alternative
mechanical methods or devices for "doffing" the bobbins.
Figures 9, and 10, are a front elevation, a part side elevation and part vertical
section drawn on a larger scale of the temper arrangement as shown applied to
Figure 7, and Figure 11, is a plan of the same, while Figure 12, is part plan
of a sliding plate or bobbin-board used in connection with the said Figures 7
and 8.
The improved mechanism employed in carrying my Invention into practice and
illustrated in the drawings consists of a shaft A, carried in bearings at either end
of and at a suitable distance along the frame. Supporting these bearings are the
moveable brackets B, and B', which are carried in guides P, formed in the gable of the
frame and connected by adjustable links C, to the curved lever D, keyed or otherwise
secured to the shaft E, having at the opposite side a counterweight E¹, which imparts
through the feed mechanism the traverse motion of the frame mounted on the
shaft A, at the proper distances from each other and screwed into or otherwise fixed
to, in a row at one side only or in rows at opposite sides of the said shaft A, are tho
bobbin-studs or pins F, which, together with the bobbins G, when the frame is running,
stand a little above the bobbin-board H.
In the bobbin-board H, are mounted the temper pins I, with the adjustable
arrangement, and rack I, for giving the necessary degree of temper to the
bobbins G. In front of the said bobbin-board H, are attached the devices for
retaining and cutting the yarn after the bobbins are filled and displaced. At a
suitable distance below the said bobbin-board H, is another bobbin-board or table H³,
for carrying the empty bobbins G', which are placed in an inverted position upon
shoes, immediately underneath the bobbins G. A series of treadles or pedals J,
are shewn corresponding to the number of flyers in the frame to these pedals J, are
attached the same number of vertical rods J', which are bent at their upper ends for
shifting the belts or straps from the driving pulleys b, to the loose pulleys c, of the
flyers K. As this part of the frame constitutes an essential feature of one of my
previous specifications No. 8111 of 1887, further reference will only be made when
found necessary in describing the operation of my present improvements.

page_text: Let it be supposed from Figures 1 and 2, of the drawings that the bobbins G, have
just been filled and the frame stopped for the purpose of "doffing" the filled
bobbins G. For this end the bobbin-board H, is retained locked in the position
shewn in Figure 2, by a projecting arm M, fixed on the longitudinal bar N, which,
being slid along, engages with a corresponding projection O, formed on the rear top
end of the moveable bracket B, and that a downward movement is about to be
imparted to the shaft A, by the attendant disengaging the heart motion by lifting the
link I, and pulling the lever L, in the direction of the arrow, Figure 3, and thereby
the shaft A, is inoved a distance sufficient to draw out the studs or pins F, from the
bobbins G, the said shaft A, is rotated about a quarter of a turn when an upward
movement of the shaft A, is necessary to enable the attendant to bring the points of
the studs or pins F, immediately over the holes of the empty bobbins G'. Such a
position is shewn in dot and pick lines Figures 1 and 2. An additional traverse of
the shaft A, causes the studs or pins F, to enter the empty bobbins G¹, and these are
thus driven home. At this point the shaft A, together with the empty bobbins G', is
raised to the position shewn in Figure 2, when, by virtue of the construction of the
bobbin-board H, Figure 4, it is free to be turned up. By this operation the empty
bobbins G, displace the full bobbins G, which fall over the front of the frame.
the said bobbins G, are falling the pivoted holders or retaining catches d, Figures 2
and 5, are opened up ready to catch and retain the several ends of yarn in front of
the cutting edges of the knives e, Figures 2 and 6, which said knives or cutters e,
when the bobbins c, have fallen to the floor or into receptacles for being removed, are
slid along by virtue of a handle formed in a sliding frame Q, to which the knives or
cutters e, are attached. The hand lever L, which transmits the necessary up and down
motion imparted to it by the heart-cam R, is thrown into gear with the hand lever L',
and the frame is then restarted. In the alternative method shewn at Figure 7, the
shaft A, for carrying the studs or pins F, and the temper arrangement only are
carried in the traversing mechanism, and the bobbin-board is dispensed with. A
different arrangement of guides and slides is used. The bracket for carrying the
temper arrangement H, is attached to or forms part of the cylindrical bar S, which
in its traverse works in the fixed guides T, and U. The link C, is coupled directly to
the shaft A.
As
The operation of "doffing" the full bobbins is effected as follows:-The sliding
plate f, is arranged under the bobbins and the studs or pins F, are withdrawn in a
manner similar to that herein described with reference to Figures 1 and 2, leaving
the full bobbins G, standing on a sliding plate f, having recesses j, corresponding to
the feet of studs and further indentations K, for the free passage of the temper pin 1,
which is shewn in the enlarged view Figure 12. The attendant then throws back the
bar V, which is pivoted to the lower bobbin-board H', and contains the holding and
cutting devices and the sliding bobbin-plate f, being withdrawn in the direction of
the arrow shown at this point the full bobbins G, being held against the fixed
ledge n, fall in front of the bar V, which, on being brought forward to its normal
position, brings the threads all into position for cutting and holding for the restarting.
A thin vertical plate m, prevents the bobbins G, in their fall passing behind the
bar V.
In Figures 9, 10 and 11, are shewn on an enlarged scale the temper arrangement
adapted for the last mentioned modification, Figure 7. Upon the stud F, Figure 10,
screwed into the shaft A, a portion of the hobbin is shewn with the temper applied.
A bar W, is suspended from the shaft A, as shewn at Figure 7, which bar W, is bent
at right angles in front of the frame, and to this bent portion of the bar W, a
longitudinal plate X, is fixed by bolts not shewn in the drawing. On the back of this
plate X, fixed studs are held by nuts h, and the vertical lever Y, vibrates on these
having the temper pin I, attached. Above the plate X, also attached to the front of
the bar W, in such a way as to admit of its sliding longitudinally is the bar X', upon
which is mounted the rack arrangement I', with the spring i, for giving the necessary
degree of temper to the bobbin G, imparted to it by the said temper pin I.

page_text: Figure 8, shews an arrangement of "doffing" the bobbins different in operation
to the foregoing but in this method the stud shaft A, and the tempering apparatus
only are carried in the traversing mechanism and the bobbin-board is dispensed with.
The operation of placing empty bobbins C, on the studs or pins F, is identical in all
the Figures.
In doffing by the method shewn in Figure S, the sliding plate f, having been
advanced either by hand or mechanically to facilitate the studs being partially with-
drawn out of the bobbins G the object of which is to cause the said plate f, to carry the
bobbins G. The plate f, is then withdrawn and the shaft A, having been lowered,
(the hobbins clearing the foot of flyers) the shaft A is rotated forward till the feet of
the studs F, drop into holes or recesses in the plate p, this plate is similar in shape to
the plate marked f, Figure 12, (but the plate in this case does not require the
smaller indentations marked K). The bobbins G, thus standing upon the plate pa
further downward motion is required to allow the studs or pins being wholly drawn
out of the bobbins G. By virtue of the construction of the plate p, and the anglo
at which the bobbins are left upon the said plate p, the said bobbins fall to the
floor.
.
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 and combination of parts constituting the improve-
ments in frames for spining, doubling, twisting, or roving jute, flax, hemp, cotton,
worsted or other fibrous substances, substantially as hereinbefore described and shewn
upon the annexed sheets of drawings.
"
"
or
2. The arrangements whereby the ordinary manual operations of "shifting
doffing" the bobbins and of "piecing" the yarns, are dispensed with, substantially
as herein before described and shewn upon the annexed drawings.
3. The arrangement of the shaft mounted in brackets and capable of moving
upwards and downwards and wherein the pins or studs for carrying the bobbins
are fixed, substantially as hereinbefore described and shewn upon the annexed
drawings.
4. The arrangements of the knives or equivalent cutters combined with holding
devices whereby the former cut the yarn after the full bobbins have been "doffed
and the latter hold the yarns as the frame starts to wind them on to a fresh set
of bobbins, substantially as hereinbefore described and shewn upon the annexed
drawings.
5. The arrangement and construction of bobbin-board substantially as hereinbefore
described and shewn upon the annexed drawings.
