Improvements in Machines for Reeling and Winding Yarns.
We, BENJAMIN ALFRED DOBSON, Machine Maker, of the firm of Dobson
and Barlow Limited, of Kay Street Works, Bolton, in the County of Lancaster,
and JOHN HILL, Foreman, Mechanic, of the same place, do hereby declare the
nature of the said invention to be as follows:-
Our invention consists in an improved method of making reels for reeling into
hank, either lea or crossed, yarns from bobbins or cops or even from other hanks,
and for reeling when required two or more ends together.
In our improved machine there is a swift for each hank to be made and these
swifts are driven independently one of the other, and each end of yarn may be
provided with a stop motion.
One method of constructing our improved reel is as follows:-
In the framing of the machine, similar to the ordinary reel, there is a central
shaft provided with strap or band pulleys and this shaft drives on either side other
pulleys having wheels or friction discs attached to them. Each swift is carried in
open bearings at the end of an upright stand and is also provided with a wheel or
friction disc on the boss of the swift; this stand is open at the top of the bearings
so that the swift may be freely lifted out. The wheel or friction disc driven by the
centre shaft is carried on a pivoted lever one end of which forms a brake acting on
the boss of the swift and the other forms a catch to engage with the stop motion;
at the other end is a handle. When the stop motiou acts the pivoted lever will fall
in a direct way from the driven wheel or friction disc and the brake will come in
contact with the boss of the swift which will stop instantaneously. When reeling
two or more ends, or reeling into leas it is necessary to have a stop motion for each
end of yarn reeled on to each swift, and in these cases the pivoted lever when
placed in proper position for working will be latched and when necessary released
by the action of the stop motion.
When used for cross reeling without any definite length requiring measurement
one traverse motion at the end of the frame will be sufficient to regulate the cross
motion for all the swifts; but when reeling in leas it will be necessary to have a
traverse motion for each swift; and this is arranged for by having on one side of
the boss of the swift a worm which gearing into a worm wheel on a shaft running
at right angles towards the outside of the framing and furnished with a cam which
will lift a notched rack against which the traverse motion is pressed by a spring
and thus lay the leas at equal distances across the swift as in the ordinary reel;
the motion being similar but self contained for each swift. When the proper
number of leas have been reeled the lifting of a notched rack for the last time will
stop the swift by putting into action the stop motion.
In the same or similar manner when a definite length of yarn is required in cross
reeling one traverse motion at the end of the machine will suffice for the whole
frame of swifts and each swift will actuate its own stop motion when the required
length has been reeled.
As each swift has reeled the required quantity of yarn it will stop automatically
and be doffed singly in the usual way, the leas or hanks being tied as usual.

Improvements in Machines for Reeling and Winding Yarns.
We, BENJAMIN ALFRED DOBSON, Machine Maker, of the firm of Dobson
and Barlow Limited, of Kay Street Works, Bolton, in the County of Lancaster,
and JOHN HILL, Foreman Mechanic, of the same place, 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 :-
Our invention consists in an improved method of making reels for reeling into
hank, either lea or crossed, yarns from bobbins or cops or even from other banks,
and for reeling when required two or more ends together.
In our improved machine there is a swift for each hank to be made and these
swifts are driven independently one of the other, and each end of yarn may be
provided with a stop motion.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is a sectional end elevation and Fig. 2 a side elevation of a machine for
reeling and winding yarn to which our improvements are applied, and Figs. 3, 4
and 5 are detailed views of parts of the machine.
In Fig 1 the left hand side of the machine is shown as arranged for cross reeling
and the right hand side for "lea" reeling. Fig. 2 is a view of the cross reeling
side of the machine, whilst the details shown in Figs. 3, 4 and 5 relate to
reeling.
"lea
In these views, a designates the frame of the machine, b supports or stands with
open bearings for the swifts c, d the central driving shaft and e strap or band
pulleys fixed thereon, straps or bands extending from the pulleys e to similar
pulleys 9 on studs ; on each stud is also fixed a pinion or friction disc i gearing
with a pinion or disc j on the boss of each swift; each stud is carried on a pivoted
lever fulcrumed on the stand b, the part of the lever forming a brake to act
on a prepared surface on the boss of the swift; the lower end of the lever k, when
in its working position, is latched by a catch on the pivoted needle box n of an
ordinary needle stop motion, which is actuated by a revolving or oscillating wiper
shaft m when an end of yarn breaks.
When used for cross reeling without any definite length requiring measurement
one traverse motion at the end of the frame will be sufficient to regulate the cross
motion for all the swifts. This arrangement is illustrated by Fig. 2 where the
thread guides o' shown in Fig. 1 are carried on a bar o which is traversed by a
revolving camp. The arrangement for cross reeling definite lengths of yarn is
hereinafter described.
When reeling in "leas" it is necessary to have a separate traverse motion for
each swift and to actuate the same intermittently instead of continuously as when
cross reeling, and such a traverse motion is shown as applied to each swift on the
right hand side of Fig. 1 and is further illustrated in detail by Figs. 3, 4 and 5.
This "lea" traverse motion consists of the following parts
On the boss of each swift is a worm which gears into a worm wheel 9 on a
vertical shaft to which is secured a pinion s gearing into a carrier wheel t which
drives a wheel u on which is a cam which at each revolution raises a double rack
bar one tooth, while a spring w draws the usual traverse step ladder and its
thread guide y forward for the next "lea" at the same time allowing a pin v on the
double rack bar to mount one step on the step ladder ..
When reeling two or more ends to form a hauk or when reeling into "leas" it is
necessary to have a stop motion for each end of yarn reeled on to each swift and
the ends of yarn are drawn from the cops shown in Fig. 1 or it might be from
bobbins or hanks through guides 2 over a drag board 3 suitably covered through a

page_text: needle 4 in the pivoted needle box n and then through one of the thread guides
on the traverse bar o or through a thread guide y as the case may be and so to its
swift c.
When an end breaks the wiper shaft m catches the respective needle 4
and moves the pivoted box n and catch which thus releases the lower end of the
lever k, the upper end of which moves away at once from the centre of the swift c
and disengages the gears i and j, while the portion of the lever comes upon the
prepared surface on the boss of the swift and acts as a brake to stop its revolution
instantly.
To re-start the swift after replacing the broken end it is only necessary to pull
the lever into the working position by means of a finger k² and latch it upon the
latch 1.
When however the pin has mounted the last step of the ladder
X, after the last
"lea" has been wound, the spring w withdraws said ladder a and an adjustable
bracket on the rack bar v comes in contact with and disengages one end of a
pivoted lever z from the double rack and the other end of said lever acts upon the
catch of the needle box n and so releases the lever k and stops the swift ċ which
it controls.
When it is desired to cross reel a definite length of yarn, which length can be
varied by changing the wheel s, the spring w is disconnected from the step ladder a
thereby allowing it and its thread guide y to remain stationary whilst a series
of guides on a single traverse bar o as shown in Fig. 2, act for the whole
number of swifts on that side of the machine; but the rack bar will be.
raised one tooth at each revolution of the cam wheel u and when the adjustable
bracket comes in contact with the end of the lever the stop motion will be
actuated as before described.
As each swift has reeled the required quantity of yarn it will stop automatically
and as it is driven independently and mounted in open bearings it can be lifted out
and doffed without interfering with the working of the rest of the machine, the
"leas"or hanks being tied as usual.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The mode of driving each swift independently of the other swifts by means of
a gear or friction disc carried by a brake lever and driven by a strap or band from
a shaft placed preferably near the middle of the machine, said lever being latched
in its working position by a catch in connection with a stop motion and released by
the withdrawal of said catch to stop the swift all substantially as and for the purposes
herein set forth.
2. Mounting each swift in open bearings and driving it independently of the
others substantially as herein described so that it can be lifted out for dofting when
required.
3. The combination with a swift driven independently of the other swifts, and the
cam wheel u driven from said swift, of the double rack bar and its adjuncts for
actuating the needle box stop motion substantially in the manner and for the
purposes described with reference to the accompanying drawings.
of
4. The combination with the gears or friction discs mounted on each swift c.
j
the driving shaft d, pulley e, strap or band f, gear or friction disc i, pivoted brake
lever k, and catch 1, all substantially as and for the purposes herein set forth.
5. The several combinations and arrangements of parts embodying our improve-
ments in machines for reeling and winding yarns substaniially as herein described
and as illustrated by the drawings annexed.
