We BENJAMIN ALFRED DOBSON, Machinist, and JOHN HILL, Foreman, both of
Bolton in the County of Lancaster, do hereby declare the nature of said Invention
for IMPROVEMENTS IN STOP MOTIONS FOR REELS AND CERTAIN OTHER WINDING
AND TWISTING MACHINES, to be as follows:-
Our invention relates to certain improvements in stop motions for reels and
certain other winding and twisting machines and our improvements consist chiefly
in the application of a needle box similar to that described in Patent No 3135 of
A.D. 1877 granted to Sidney Emsley and Samuel Smith, this needle box extends
the entire or part length of the swift, and it contains as many needles as there are
ends of yarn to be wound or reeled. The needle box is pivoted in such a manner
that when deflected it returns to the working position by its own weight: a lover
or attachment connects the end of the needle box to the strap fork guide which ⚫
controls the driving belt of the swift or reel. Underneath the oscillating needle
box is a vane shaft or wiper shaft driven from the particular swift or reel to which
the stop motion is attached.
When an end of yarn breaks its needle falls and the wiper on the shaft coming in
contact with the needle moves the oscillating needle box a certain distance and
causes the strap fork to move the strap from the fast to the loose pulley on the
swift or reel; at the same moment a brake being automatically applied, the machine
comes to a stand.
The machine may be driven by friction, catch box or otherwise, and the lever
arranged to disengage the driving power and apply a brake.
In this stop motion the yarn before passing through the eye or loop of the needle
traverses preferably over a drag board placed in front of, and a little above, the
level of the needle eye and this drag board may be attached by brackets to the
pivoted needle box; in this position the drag board acts as a preventative of
ballooning" in the ends of yarn being reeled or wound, besides assisting the ends
to maintain the weight of the detector needles.
This invention is more particularly applicable to those reels in four sections
known as "
Coleby's" reels and certain other winding and twisting machines in
which swifts are employed.

We BENJAMIN ALFRED DOBSON, Machinist, and JOHN HILL, Foreman, both of
Bolton in the County of Lancaster, do hereby declare the nature of said Invention
for IMPROVEMENTS IN STOP MOTIONS FOR REELS AND CERTAIN OTHER WINDING
AND TWISTING MACHINES, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Our invention relates to certain improvements in stop motions for reels and
certain other winding and twisting machines and our improvements consist chiefly
in the application of a needle box similar to that described in Patent No 3135 of
A.D. 1877 granted to Sidney Emsley and Samuel Smith; this needle box extends
the entire or part length of the swift and it contains as many needles as there are
ends of yarn to be wound or reeled. The needle box is pivoted in such a manner
that when deflected it turns to the working position by its own weight. A lever
or attachment connects the ends of the needle box to the strap fork guide which
controls the driving belt of the swift or reel.
When
Underneath the oscillating needle box is a vane shaft or wiper shaft driven
from the particular swift or reel to which the stop motion is attached.
an end of yarn breaks its needle falls and the wiper on the shaft coming in
contact with the needle moves the oscillating needle box a certain distance and
causes the strap fork to move the strap from the fast to the loose pulley on the
swift or reel, at the same moment a brake being automatically applied, the machine
comes to a stand.
The machine may be driven by friction, catch box, or otherwise and the lever
arranged to disengage the driving power and apply a brake.
In this stop motion, the yarn before passing through the eye or loop of the
needle traverses preferably over a drag board placed in front of, and a little above,
the level of the needle eye, and this drag board may be attached by brackets to
the pivoted needle box; in this position the drag board acts as a preventative of
"ballooning" in the ends of the yarn being reeled or wound besides assisting the
ends to maintain the weight of the detector needles.
This invention is more particularly applicable to those reels in four sections
known as "Coleby's" reels and certain other winding and twisting machines in
which swifts are employed.
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.
Figure 1 is a side elevation. Fig. 2 a front elevation and Fig. 3 a plan of the
driving portion of a machine for winding or reeling to which our improvements are
applied.
The machine shown in the Drawings is what is known as a "Coleby's" reel in
which four swifts are employed, two on either side of the frame, each swift is

page_text: driven by separate gearing and has a separate stop motion--For the sake of
clearness we will refer in detail to one side of the frame only.
In these views. -a is the frame of the machine and b b are two of the swifts;
cc are two driving pulleys each of which runs loose on a bush or sleeve fitted on
the driving shaft x and is provided with internal clutch teeth on its boss at c' to
receive the corresponding teeth on a clutch d which is fitted and free to slide on a
feather key on the bush. Also fixed one on each of the bushes are toothed wheels e
which gear into toothed wheels f fixed on the axles b' of the swifts b and so drive
each swift when its clutch d is in gear with its driving pulley c; each wheel e also
drives a wheel g on the boss of which is a grooved pulley g¹ which drives by a
band h a grooved pulley i fixed on a wing or wiper shaft j. The yarn to be reeled
is drawn from the bobbins k mounted on spindles carried by the creel board a¹
and the yarn passes over a drag board 7 through the eyes of the detector needles or
wires m held in a needle box or plate n pivoted at each end to the frame a directly
over the revolving wing shaft j. The yarn passes from the detector needles m over
the guide plate o to the swift b. The drag board is supported by brackets l' cast
with or secured to the needle box n to which is also secured an arm or lever n¹
which rests immediately under the lower end of the starting lever p which is
pivoted at q¹ to a rod or shaft q supported and free to turn in suitable bearings in
the frame a and connected by a forked lever q' to the sliding clutch d.
When the machine is running, the upper portion of the starting lever p rests at
as in a notch in the frame a, and an arm pl secured to the starting lever p supports
the weighted end 71 of a brake lever which is pivoted to the frame at and the
other end or brake portion of which rests under the axle b¹ of the swift b. Immc-
diately below and in contact with the weighted end 1 of the lever there is the
end of a lever s, the other end of which is secured to a shaft s¹ upon which are
mounted as many brake levers t as there are bobbins k. The brake levers t are so
mounted that when the machine is in motion they are held clear of the bobbins k
by the shaft s but immediately the machine is stopped and the shaft s¹ moved as
hereinafter described each brake levert falls forward against the flauge of its
bobbink thereby stopping the rotation of all the bobbins.
When the starting lever p and the other parts are in the position shown in the
Drawings, the clutch d is engaged with the teeth on the boss c¹ of the driving
pulley c and as the clutch d and the bush on which it slides revolve the wheel e
also revolves and motion is transmitted as described by the wheel and axle b¹ to
the swift b and by the wheel g, pulley g', band h, and pulley i to the wing shaft j,
and as the swift b revolves yarn is drawn from the bobbinsk over the drag board
through the detector needles or wires m, over the guide plate o to the swift bon
which it is reeled; but as soon as a thread breaks or fails the detector needle m
through which it has been passing falls, and is struck by the revolving wing shaft j
which causes the needle box n to oscillate or turn on its pivots, and the arm or
lever n¹ moving with it, lifts the lower end of the pivoted starting lever p and 80
unlatches the upper end at a², the starting lever p then falls rapidly sideways in
the direction indicated by the arrow, shown in Fig. 2, its own weight being assisted
by the action of the weighted end r¹ of the lever r and also by the spiral spring u,
and as the lever p falls it turns on its axis the shaft q, on which it is pivoted
thereby causing the clutch lever q' to slide the clutch d out of contact with the
teeth on the boss c¹ of the driving pulley c, which thus ceases to drive the swift b,
the revolving motion of which is immediately stopped by the braker which is
applied to the axle 61 as soon as the arm pl moving with the lever p allows the
weighted end of the lever to fall and when this takes place, the end of the
lever 8 is also depressed thereby partly turning the shaft s¹ and applying the brakes t
and stopping the bobbins k.
The whole machine having been stopped in this manner the end of yarn may be
pieced and when this has been done the machine can be re-started by moving the
handle of the starting lever p and replacing the said lever in the notch a³ thereby

page_text: moving the clutch & into gear with the boss c' of the driving pulley c and replacing
the other parts in their working positions as shown in the Drawings.
In place of the toothed clutch driving mechanism herein shown and described the
machine may be driven by friction, or otherwise and the starting lever p so arranged
that when released it will disengage the driving mechanism and apply a brake to
the swift in the manner already described.
It is obvious that when the yarn is drawn from cops on spindles in place of from
the bobbins k, the lever a would be dispensed with, as the brakest would not be
required.
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 use and application of a needle box stop motion, substantially as described,
for reels and certain other winding and twisting machines.
2. In a reeling or winding machine, the combination with the detector needles m,
oscillating needle box n, and revolving wing shaft j, or its equivalent, of means for
stopping and re-starting the driving mechanism of the machine, substantially as and
for the purposes herein set forth.
3. In a reeling or winding machine, the combination with the pivoted starting
lever p by which the driving mechanism and brake apparatus are controlled, of the
detector needles m, needle box n, and revolving wing shaft j, all substantially as
and for the purposes herein set forth.
4. In a recling or winding machine, the detector needles m, the needle box n,
and the revolving wing shaft j, in combination with a brake for the swift, and,
when required, with brakes for the bobbins, substantially as herein shown and
described for the purposes specified.
