Improvements in Spinning, Twisting, and like Machines.
I, FRED HAGGAS, Senior, of Providence, Rhode Island, United States of
America Superintendent, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the class of stop-motions used on spinning frames,
twisters, and like machines.
The object of the invention is to produce a stop-motion that will operate to stop
the machine if the belt that drives that part of the mechanism that governs the
laying of the thread on the cop or bobbin, breaks or runs off the pulleys.
I will describe my invention as applied to a spinning frame comprising end
frames, a band cylinder held on the shaft, which runs in bearings in the end
frames, driving pulleys fast on one end of the shaft and a belt that runs the
machine. A shipper rod is provided having a belt guide on its outer end. The
machine is also provided with a ring, or cop rail, according to the make of the
machine, that governs the laying of the thread on the cop or bobbin. A rising
and falling motion is given to this rail, through vertical rods, and chains which
connect the rods to a horizontal rod.
The horizontal rod is turned down at one end and has a friction roll, pivoted
to it, which bears on a cam, that is held on a cross shaft. The cross shaft is
moved by a worm gear, fast on it that engages in a worm held on a short shaft
that extends through the end frame in a long bearing fast to the end frame.
The outer end of the shaft has a gear fast on it, that engages with a gear fast
on a sleeve, held to turn on a stud, also fast in the end frame. A pulley is made
fast on the outer end of the sleeve, and is connected by a belt to a small pulley
fast on one end of the cylinder shaft. In this way motion is conveyed from the
said shaft, through the cam, to the horizontal rod and the rail. The usual start-
ing and stopping of the machine is done through the shipper rod having the
belt guide on its outer end and a short arm having a hole with a screw thread
in it, on its inner end. A screw shaft, having one bearing in the end frame,
and another bearing in a standard attached to the end frame, has a screw thread
made on it that fits in the thread in the arm of the shipper rod. The outer end
of the screw shaft, has a hand wheel, made fast on it, by turning which the shipper
rod can be moved endways either way to move the belt, to start or stop the
machine. A notch is made in the end of the arm, and a projection made on one
end of a collar fast on the screw shaft, to catch in the notch, when the arm
is nearly to the hub, to stop the shaft before the arm is jammed against the
collar. A small gear is held on the screw shaft, near the frame, and a larger
gear, held on a stud fast in the end frame, engages with it. This larger gear
has a bevel gear fast on its outside which engages with a bevel gear held loosely
on a vertical shaft. The said vertical shaft is held to turn and slide in brackets,
fast on the end frame. As before stated the stop-motion is to prevent the break-
ing or running off of the belt from spoiling the cop, by winding the thread in

page_text: a ridge. This is effected as follows:-a forked bracket fast in the end frames
has a cam pivoted in the fork and a small arm, projects from the cam, and rests
lightly against the belt, when that belt is in place. The lower end of the
vertical shaft rests. on the face of the cam and is held up by the cam so long
as the cam is held up by the arm thereon resting against the belt whilst
the shaft is held in this way a worm gear fast on it will be held up from
engaging with a worm fast on the cylinder shaft but if the belt
breaks or is thrown off the pulleys, the cam and armı will turn over
by their
own weight and allow the shaft to drop the worm gear,
into gear with worm which will put the shaft in motion, and when the said
shaft drops a pin in its upper end drops into one of the slots in the top of the
gear which starts the said gear and the bevel wheel which is in gear therewith,
which by means of the toothed wheel on the same shaft, starts the pinion and
the screw shaft and moves the driving belt by means of the shipper rod, onto
the loose pulley and stops the machine. By reason of the great speed usually
given to the band cylinder, and the increase of that speed by the gears on the
stud and screw shaft, the stopping of the machine, when the lower belt slips off,
is accomplished at once before any damage can be done.
The invention is applicable to spinning frames, twisters, and to most machines
using a reciprocating rail to lay the thread on the cop or bobbin.

I, FRED HAGGAS, Senior, of Providence, Rhode Island, United States of
America, Superintendent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
-
This invention relates to the class of stop-motion used in spinning frames,
twisters, and like machines.
The object of the invention is to produce a stop-motion which will operate
to stop the machine if the belt which drives that part of the mechanism which
governs the laying of the threads on the cop or bobbins, breaks or runs off of
the pulleys, and also to stop the machine when the bobbins are ready to doff.
Referring to the accompanying drawings:
Figure 1 is a front elevation of a portion of a spinning frame showing the
devices used in the stop-motion.
Figure 2 shows an end view of the machine mainly of the parts connected
with the stop-motion.
Figure 3 is an enlarged top view of a part of the stop-motion mechanism.
Figure 4 is a side view of a part of the starting and stopping mechanism of
the machine.
Figure 5 is an enlarged view of the upper portion of the release motion.
Figure 6 shows a part of the lower belt, and cast off, and
Figure 7 shows the details enlarged of the parts that govern the stop-motion
with regard to stopping to doff the bobbins.
In the drawings A, A, denote the end frames of the machine, C, is the band

page_text: cylinder held on the shaft F, which runs in bearings in the end frames.
B indicates the driving pulleys fast on one end of the shaft F, and G, is the belt
which runs the machine. H, is the shipper rod having a belt guide H¹ on its
outer end.
D, is the ring, or cop rail made according to the class of machine and which
governs the laying of the thread on the cops or bobbins L. A rising and
falling motion is given to this rail 1 by means of vertical rods T, T, and the
chains Y, Y, which connect the rods to the horizontal bar S.
To the end of the bar S, is bolted a hollow bracket k, which is screw threaded
to receive the screw threaded end of the rod S¹ which extends through the end
frame A, and is provided at its opposite end with a hand wheel O, made fast
thereon. An upright lever V₁, is held on a stud y, in a bracket made fast to
the floor. This lever V, extends up beyond the end of the hollow bracket k,
and is provided with a bracket Y¹ carrying a friction roll the said bracket being
adapted to be adjusted vertically upon the said lever.
Another lever U, is pivoted at U* and adapted to hang down in engagement
with the friction roll on the lever V, and provided with a friction rolls, upon
the opposite side therof, which latter bears against a cam 61 secured to a cross
shaft N, operated by a worm gear N¹ engaging a worm P¹ secured to a short
shaft v, arranged in a long bearing P in the end frame A. To the outer end
of the shaft c, is secured a gear ¹, engaging a gear d¹, fast on a spindle d,
adapted to turn in a bearing, secured to the end frame A. A pulley g, is
secured to the outer end of the spindle d, and is connected by a belt R, to a
small pulley f, fast on one end of the cylinder shaft F.
In this way motion is communicated from the shaft F, through pulley g
gears d¹¹, worm P¹, and cam 6', to the bar S, and the rail D. The usual
starting and stopping of the machine is effected through the shipper rod H,
having a belt guide H¹ at one end, and at its opposite end provided with a short
arm a, having a screw threaded hole adapted to receive the screw threaded part
of a shaft J, Figure 4, having one bearing in the end frame, and another bearing
in a standard C, attached to the end frame.
The outer end of the shaft J, has secured thereto a hand wheel o, by which
the shipper rod H, can be moved endways either way to shift the belt G, to
start or stop the machine. A notch e¹, is made in the end of the arm a, see
Figure 4, and a projection *, on the end of the collar J', fast on the screw
shaft is adapted to catch in the said notch e, when the arm a, is near the
hub, to stop the shaft J, before the said arm a, is jammed against the collar J¹.
A small gear a¹, is held on the shaft J, near the frame, see Figure 2, and a larger
gear r, held on a stud y¹, fast in the end frame, engages with it.
This larger gear 1, has attached to its outerside a bevel gear h', which
engages with a bevel gear r, held loosely on a vertical shaft K. The said
shaft K, is held to turn and slide in brackets n, n, fast on the end frame of
the machine.
As before stated one object of the stop-motion is to prevent the breaking
or running off of the belt R from spoiling the cop by winding the thread in a
ridge.
The manner in which this is effected is as follows:-A lever e, see Figure 5,
pivoted to the end frame A has a cam j pivoted near its outer end o¹, and a small
arm t, projects from the cam j, and rests lightly against the edge of the belt R,
when the latter is in place as shown in Figure 5.
The lower end of the vertical shaft K, rests on a lever K³, the free end of
which rests on the face of the cam j, and is held up by the said cam as long as
the latter is held up by the arm t, resting against the belt R. Whilst the
shaft K, is held in this position the worm gear c', fast thereon will be held out of
engagement with the worm c, fast on the cylinder shaft F, but if the belt R
should break, or be thrown off the pulleys, the cam j, and arm t, will turn over
by their own weight and allow the shaft K to drop so that the worm gear c¹

page_text: will be moved into gear with worm c, to start the shaft K When the said
shaft drops, a pin h in its upper end, see Figure 3; engages with one of the
slots in the top of the gear which thereupon- starts the said 'gear' and the
gear meshing therewith so as to operate by means of the gears, and a',
the screw shaft J, and move the driving belt by means of the shipper rod, onto
the loose pulley to stop the machine.
To provide for the stopping of the machine when the bobbins are ready to
doff, a short shaft T¹, arranged in a bearing in the end frame A, has a worm
gear m, fast to its inner end, which worm gear engages with a worm s¹, fast
on the cam shaft N, see Figure 7.
A gear m¹, fast on the outer end of the shaft T", is connected by a pair of
change gears 1, 2, with a gear 3, adapted to 'slide on and turn with the rod Si
by means of a spline in the gear and a slot in the said rod.
A rocker shaft R'; is held in bearings on the end frame A, and has a vertical
arm P, loose thereon provided with a pin w*, that engages a pin in a collar w¹,
fast on the said shaft R¹. The arm P has a dog b pivoted to its upper end see
Figure 7, and adapted to straddle the rod S¹. This rod is provided with a collar /
adjustable thereon, by means of a set screw and adapted to operate the said
arm P..
.
When the worm s¹, and train of gears m, m³, 1, 2, and 3, have moved the
rod S far enough out of the socket k, to bring the collar 1, against the arm P,
then the bar S, may be let down.
When the collar 7, has pushed the arm P, over far enough to trip the dog b,
see Figure 7, by pushing it against the set screw 2, in a bracket fast on the
end frame A, the vertical arm g of the bell-crank lever fast on the same shaft,
see Figure 2, will move the hook e¹, on its upper end into the position of the
dotted lines in Figure 5 and at the next outward movement of the rod S¹ the
collar, will strike the end of the fork or dog b and push the arm P, over to
the position indicated in dotted lines in Figure 7, which will turn the shaft R¹
and arm and throw the hook e¹ off the end of the lever e and let the cam j,
drop and allow the shaft K, to fall and stop the machine in the same manner
as described when the belt R, breaks or slips off the pulley f.
When the machine has stopped automatically to doff, the rod S¹, is screwed
back into the hollow bracket k, by means of the hand wheel O, until the pin *
in the collar, engages with the pin 12, on the lever V1, when the machine is
ready to start again. To give the cast off mechanism an easy start and avoid
a shock when the shaft K, drops the worm gear cl, into engagement with the
worm c, the gear is held loose on the shaft and is connected with a collar 2,
fast on the shaft K, by a stiff spiral spring ³, which has one end fast to the
gear c¹ and the other end fast in the collar c², and a collar i, fast on the shaft K,
just above the worm gear ¹, has two prongs 22, on its under side that engage
with two prongs, in the upper side of the gear c¹, after the spring c³, has taken
the first shock of starting.
To allow the shaft J, to shift the belt automatically and not jam the arm a,
hard against the inner bearing the thread on the shaft is turned off for a short
distance from the end so that the arm a, will stop when it has gone far enough
to move the belt off the fast pulley, and to provide a check when the belt is turned
off by the hand wheel O, a small shaft n¹, is arranged in a bearing in the end
frame see Figure 4, having a lever n² fast on its outer end, with one end
of the lever held under a collar m² fast on the shaft K, and a weight 102, on
the opposite end of the lever, to hold up the arm t¹, on the inner end of the
shaft n', with a flat disk n³, that is arranged to lie against the shaft J, where
the thread is turned off and stop the arm a, before it runs off the thread when
turned by hand, but when automatically stopped by the dropping of the shaft K,
the collar m³, will tip the shaft over and turn the arm n² and disk n³, over out
of the way and the arm a, will run off the thread before stopping the machine.
small stop clip d which projects into the centre of the cam 2 is bolted on the
A

page_text: lever e, see Figure 5, and is formed with recesses to limit its motion each way, and
the arm t, is made in such a way that it may be adjusted as desired see Figure 6.
By reason of the great speed usually given to the band cylinder, and the
increase of that sneed by the gears on the stud and screw shaft, the stopping
of the machine when the lower belt slips, is accomplished at once before any
damage can be done. The invention is applicable to spinning frames, twisters,
and to most kinds of machines using a reciprocating rail to lay the thread on the
cop or bobbin.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a stop-motion for spinning machines, twisters, and like machines, the
combination with the main shaft, of a pulley fast on said shaft, a belt connecting
said pulley with a lower pulley, said lower pulley, means for turning the lower
pulley, a cam with an arm arranged to rest against said belt, a worm fast on the
main shaft, a vertical shaft held to slide in brackets on the frame, a worm gear
on said vertical shaft, a bevel gear held loosely on the upper end of the vertical
shaft, a vertically arranged bevel gear held on a stud and engaging with the
loose bevel gear, a spur gear fast on said vertically arranged bevel gear, a gear
held on a horizontal shaft and engaging with the spur gear, and mechanism
connecting said horizontal shaft with the driving belt, substantially as described.
2. In a stop motion for a machine of the character described, the combination
of a shipper rod, an arm fast thereon and having a hole in its free end with a
screw thread made in it, and a notch made below said hole, a shaft having a
screw thread made on it, fitting in the hole in said arm, a collar fast on said shaft
and having a projection on its inner end arranged to catch in said notch and
stop the shaft, with means for turning said shaft, substantially as described.
3. In a spinning machine the combination of the parts of the within described
mechanism for automatically stopping the machine when the belt that drives the
mechanism for raising the ring or bobbin rail, slips off its pulley, substantially
