Improvements in Stop Motions and Knocking-off Motions of Beam
Warping Machines and other similar Machines.
We, BENJAMIN HOLT and FRANK ASHWORTH HOLT, both of Thomas Holt
Limited, of Atlas Iron Works, Molesworth Street, Rochdale, in the County of
Lancaster, Machine Makers and Ironfounders, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in stop motions and knocking off motions
of beam warping machines and other similar machines and the objects of our
invention are first to simplify the electric stop motion for stopping the machine
when an end breaks, also to stop the machine electrically by hand pressure
whether an end is broken or not and further, to construct an improved measuring
motion which will operate either an electric or mechanical knocking off motion.
In carrying the first part of our invention into effect we arrange the bobbins of
yarn preferably in a Vereel and we employ the ordinary guide rods which are
attached to the uprights of the creel and extend from the top to the bottom
and we utilize these rods to serve as part of the electric stop motion. A strip
of metal placed near to and parallel to the guide rod is fixed upon each of the
uprights and elbow shaped or bent wires are pivoted at one end to screws or studs
on these metal strips and at the other end are formed into curls. Each thread
of yarn passes first over the guide rod then through the curl of one of the bent
wires and through a stationary curl on the same upright in its passage to the
beaming machine. The guide rods and the strips of metal are all connected by
wires to an electric generator and so long as all the threads of yarn are pieced up
there is no electrical contact between the strips of metal and the guide rods but
as soon as an end of yarn breaks its bent wire falls and one portion of it
comes into contact with the guide rod over which it passes and thus the circuit
between the strip of metal and the guide rod is completed and a magnet placed
between the generator and the creel actuates the knocking off motion and stops the
machine.
The knocking off is effected preferably by a magnet placed near one end of a
pivoted lever and when the circuit is completed by the breaking of an end of yarn
or by hand or from the measuring motion the end of the lever is moved by electro
magnetic force thus bringing the other portion of the lever into contact with a lever
kept constantly oscillating or moving by any part of the mechanism, the movement
of these levers knocking off and stopping the machine which cannot be re-started
until the electric circuit has been broken which is effected when all the broken ends
have been pieced.
In order to prevent the lever actuated by the magnet from moving when the
machine is stopped we employ a switch connected to the electric generator which
switch is out of contact with the vertical lever of the starting motion when the
machine is stopped and thereby breaks the electric circuit and render the magnet
inoperative but as soon as the machine is re-started the lever is raised and the
circuit is again completed.
Our improved measuring motion is applicable to beam warping and similar
machines and it consists of a casing which contains a number of discs and special
ratchet wheels all mounted loosely upon a shaft and we employ a worm and worin

page_text: wheel to turn the first disc, a ratchet motion being introduced between the worm
wheel and the disc to allow the latter to be turned independently of the worm wheel,
each disc carries on it's periphery numerals say from 0 to 9 and on each disc except
the first is secured a ratchet wheel with ten teeth; the ratchet wheels on the
adjoining discs come against one another and one ratchet wheel is smaller than its
neighbour pivoted to the casing are two pawls the first of which is actuated by a
projection cast upon the first disc and the second pawl is actuated by a projection
on the third disc the face of the pawls being wide enough to lie across the two
ratchet wheels. In this manner when a disc and ratchet wheel have made ten move-
ments the pawl has fallen into the deep tooth and at this time it moves the smaller
ratchet wheel one tooth and when the smaller wheel has moved once round it gives
to the next disc one movement.
In order to stop the beaming machine at any desired time we pivot a ratchet
catch below or near each disc each ratchet catch resting in a notch formed in a bar
free to slide through the casing and below each ratchet catch is mounted a small
cam or equivalent by which the catches can be thrown out of action when
required.
Supposing that lengths indicated by three figures only where required, say three.
hundred and forty five yards, then a movable stop would be put in the third disc
indicating hundreds at (3) then, in the tens disc a stop would be put in at 4, and in
the units disc a pin at 5, and the machine would run. until the stop in the hundreds
disc came against and pressed down the upper end of its ratchet catch thus removing
the catch from the bar, next the second pin would act upon its ratchet catch and
raise it from the bar, and then the third pin would act upon its catch and raise it
from the bar which bar being drawn in one direction would by electrical contact
with the generator or by mechanical means actuate the knocking off motion and
stop the machine.

Improvements in Stop Motions and Knocking-off Motions of Beam
Warping Machines and other similar Machines.
We, BENJAMIN HOLT and FRANK ASHWORTH HOLT, both of Thomas Holt
Limited, of Atlas Iron Works, Molesworth Street, Rochdale, in the County of
Lancaster, Machine Makers and Ironfounders, 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 relates to improvements in stop motions and knocking off motions
of beam warping machines and other similar machines and the objects of our
invention are first to simplify the electric stop motion for stopping the machine
when an end breaks, also to stop the machine electrically by hand pressure whether
an end is broken or not, and further, to construct an improved measuring motion
which will operate either an electric or mechanical knocking off motion.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying three sheets of drawings reference being
had to the figures and letters marked thereon.
Fig. 1 is a side elevation. Fig. 2 a plan of part of a creel fitted up with our
improved electric stop motion, and Figs. 3 and 4 are views of part of the same on
an enlarged scale.
Fig. 5 is a similar view to Fig. 1 showing a small part of the creel fitted with an
alternative arrangement.

page_text: Fig. 6 is a side elevation of part of a beaming machine to which is applied
our improved electric stop motion, actuated either by the measuring motion or by
broken ends from the creel, and Fig. 7 is a plan view of part of Fig. 6.
Figs. 8 and 9 are two views showing the application of our improved measuring
motion to a mechanical stop motion.
Fig. 10 is a side elevation (with the front of the casing removed) of our
improved measuring motion. Fig. 11 is a plan view of the same omitting a number
of parts. Fig. 12 is an end view of Fig. 10, and Fig. 13 is a transverse section on
the line A B, Fig. 11, and Fig. 14 is a detail view.
In the drawings, the top horizontal bars are marked 2 and the upright bars of
the creel 3 for supporting the bobbins of yarn 4 which are preferably set as shown;
to one of the upright bars for each row of bobbins is secured two narrow strips say
of copper 5, 6, see Figs. 3 and 4, each end of yarn from the creel 7 passes through
an eye in an elbow shaped or bent wire 8 pivoted on a screw secured to the metal
strip 5; secured to the other strip 6 near each guide wire 8 is a projecting screw 9;
the yarn preferably passes from the eye in 8 through a fixed eye 10 and then over
the ordinary upright wire 11 attached to one of the uprights 3 from which it passes
to the reed 12, see Fig. 6. The metal strips 5, 6, on each upright 3 are bent over
their top horizontal bar 2, see Fig. 3, and all the wires 5 are connected together
and the strips 6 are also connected together by horizontal strips of metal 13, 14,
secured to the bars 2. The metal strip 13 is connected by a wire 15 to a screw. 19
on the machine and the strip 14 to an electro maguet 17 by wires 18, see Figs. 1
and 6. A wire 15" from a dynamo or electric generator 16 is connected to a brass
spring clip 19 insulated from the machine side, and the magnet is also connected
by a wire to the machine frame while the dynamo and magnet are connected
together by a wire 20. A wire 21 from the magnet is connected to a hand push 22.
on each side of the machine for stopping the machine by hand.
To the frame 23 of the beaming machine is bolted a bush 24 with an inclined
face; this bush carries one end of a shaft 25 on which is secured a driving drum 26
on which the warp beam 27 rests and by which it is driven; on the shaft 25 is
mounted loosely a driving pulley 28 with a grooved rim 29 to give motion by a
band 30 to a pulley on the dynamo 16; secured to the boss of the pulley is a
recessed disc or cam 31 and secured to the shaft is a friction plate 32 which acts
upon a prepared surface on the inner flange of the pulley when the parts are in the
position shown in Figs. 6 and 7. Mounted loosely upon the shaft 25 is the boss of
a lever 33 which has an inclined face opposite that on the bush 24; one end of this
lever is slotted and the other end has a stud 34 to which is pivoted one end of a
bar 35 which is notched near its upper end where it passes through a slot in a
bracket 36 secured to the frame and is held there by a spring 37. Below this
bracket and nearly in contact with the bar 35 is a horizontal notched bar 38 carried
by the upper end of an arm 39 pivoted to the frame at 40; the lower part of the
lever 39 is connected by a spring 41 to a lever 42 pivoted to the frame at 43, and
the lower curved end of this lever is maintained by the spring 41 in contact with
the surface of the cam 31 by which it is oscillated. A lever 44 pivoted to the
frame at 15 has a stud 46 which rests in the slot in the lever 33 and carries a
weight 47 at its other end which maintains the parts in the position shown. The
measuring roller 48 is turned by the yarn 7 which passes over it in its passage
from the reed 12 to the warp beam 27 and the casing 49 of the measuring motion
has a slot 50 in the front covered with glass; in bearings at 51 at each end of the
0 casings is fitted a stationary shaft 52 and a bevel wheel 53 on the measuring roller
shaft 54 gears into a bevel wheel 55 fixed upon a stud 56 carried in a bracket 57
on the casing 49; a worm 58 on this stud gears into a worm wheel 59 loose on
the shaft 52; a pawl 60 secured to this wheel rests in the teeth of a small ratchet
wheel 61 loose upon the shaft 52 the boss of which passes through the bearing of
5 the shaft to the interior of the casing and fixed upon this boss is the first or unit
dial 62 of the counting apparatus shown on Sheet 3. There are five dials in all,
62, 63, 64, 65, 66, those marked 63 to 66 all being loose upon the shaft 52, each

page_text: dial has a boss attached to it and ten small radial holes are drilled in each boss to
correspond with the numerals from 0 to 9 on the dials; the dials 62 and 64 have a
short pin 67 on the face of their boss while 63 and 65 have ratchet teeth 68, 69,
respectively cut on their bosses and 64 and 66 have ratchet teeth 70, 71, respectively
cut upon their smaller bosses. Pivoted upon a stud 72 which extends across the
interior of the casing are a pair of elbow levers or catches 73; one end of these
catches is actuated by the pins 67 and to the other end of ench is pivoted a pawl 74,
springs 75 serving to keep the catches in the position shown in Fig. 13. A spring
clip 76, see Fig. 14, is placed over each boss and is held in any desired position by
a pin 77 which fits into one of the holes referred to, the projection 78 engaging with
and raising the end of a weighted lever 79 which rests normally in a notch cut in a
bar 80. This bar is slotted at 81 and guided by screws 82 and is normally in the
position shown in Fig. 10, a spring 83 tending to push the bar to the left hand when
released by the acting levers 79 into contact with a piece of metal 84 insulated from
the casing, see Fig. 11; an electric wire 85 is carried from this piece to the electro
magnet 17.
In operation suppose it is desired to measure say 1250 yards, the first four dials
only would be required and they would be moved to bring the numerals 1250 to
the top of the dials, the spring clips 76 are brought with their projection 78 in line
with those numerals, the pins 77 holding them in position; the dials are then turned
to bring the ciphers opposite the glazed slot 50 and the last dial 66 is turned until
its lever 79 is raised out of its notch in the bar 80.
The motion of the beaming machine is conveyed to the first dial 62 as described
each rotation of which brings a pin 67 under its elbow lever 73 and causes the
pawl 74 to move the dial 63 one tooth on the ratchet wheel 68; this wheel has one
extra deep tooth 68 and when the pawl enters this tooth it also turns the ratchet
wheel 70 on the third dial 64; a più 67 on the boss of this dial actuates at every
rotation a second elbow lever 73 which causes a pawl 74 to move the ratchet 69 on
the dial 65 one tooth; this ratchet wheel also has an extra deep tooth for the
purpose before described. When the numeral I on the dial 65 comes opposite the
glass the projection 78 will come against and lift its lever 79 out of its slot in
the bar 80, the same action takes place when the numeral 2 on the dial 64, the
numeral 5 on the dial 63 and the numeral 0 on the first dial 62 comes opposite
the glass at which time all the levers 79 will be lifted from the bar 80 and the
latter will be moved by the spring 83 into contact with the metal plate 84 which
is connected by the wire 85 to the electro magnet 17 and as the casing 49 is in
electric contact with the frame of the beaming machine the movement of the
bar 80 thus puts the machine stop motion into immediate operation to stop the
machine.
When the beaming machine is in operation the parts occupy the position shown
in Figs. 6 and 7 the dials of the measuring motion being set for the required length.
The ends of yarn 7 from the creel pass through their bent wires 8 and through the
reed 12 over the measuring roller 48 which is turned by the friction of the yarn as
it is wound upon the warp beam. When an end of yarn breaks its bent wire 8 falls
thus bringing the other end of 8 into contact with its screw 9 whereby an electric
connection is formed between the strips 5, 6, which are in contact with the
strips 14 and 13 which are electrically connected to the magnet 17 and dynamo 16
and the electric circuit being thus closed the magnet actuates the bar 38 by which
the stop motion is put into action to stop the machine. Further the machine will
be stopped in the ordinary course when the required quantity of yarn has passed
over the measuring roller 48 by the closing of the electric circuit consequent upon
the release of the bar 80.
Again the electric circuit may be closed at any time by the hand push 22.
When the machine is stopped the current of electricity is broken at the lever 35
because the lever has moved out of the spring clip 19" and therefore the lever 38
can fall away from the magnet 17 and no current passes through the machine. In
either case whenever the electric circuit is closed the magnet immediately attracts

page_text: the lever 38 lifting one end and depressing the other thereby latching its hooked
portion upon the oscillating lever 42 which, as the cam 31 turns, moves forward
the lever 38 and pushes back the vertical bar 35 and unlatches it from the bracket 36
and immediately this takes place the bar 35 is drawn down by the levers 33, 44 and
the weight 47; the movement of the lever 33 causes the inclined face on its boss
to turn upon the inclined face of the bearing 24 thus bringing the lever 33 nearer
to the bearing and allowing the pulley 28 to slide away from the fast friction
plate 32 whereby the pulley 28 runs idly on the shaft 25 and the machine comes to
a stand.
To re-start the machine the treadle on the lever 44 is depressed which brings the
parts into position shown in the drawings with the bar 35 hooked on to the
bracket 36 where it is maintained by the spring 37.
In Figs. 8 and 9 a mechanical arrangement of knocking off motion actuated by
the measuring roller 48 is indicated the parts necessary to illustrate the improvement
alone being shown; the vertical rod 35 is hooked on to the bracket 36 and held
there by a spring 37; pivoted to the frame of the machine at 89 is a lever 86 one
end of which is supported by a hooked wire 87 suspended from the bar 80 or its
equivalent actuated by the measuring motion; to the other en 1 of the lever 86 is a
striking bracket 88 which rests near to the bar 86. When the regulated length of
yarn has passed over the measuring roller 48 the bar 80 which supports the hook 87
is moved to release the latter when the long end of the lever 86 falls and so brings
the striking bracket 88 into contact with the vertical bar 35 and moves it from its
support on the bracket 36, the weight 47, see Fig. 6, then acts to stop the machine
as before described.
Our improved electric stop motion can be employed in combination with any
suitable measuring motion and our improved measuring motion can be employed in
combination with any suitable stop motion.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
