Improvements in Self-stopping Motions, Applicable to Machinery for
Knitting Cotton, Wool, and other Fibrous Substances.
We, WILLIAM HENRY HOYLE and JOHN TAYLOR of the Turton Manufacturing
Company, Turton near Bolton in the County of Lancaster, Hosiery Manufacturers, do
hereby declare the nature of our said invention to be as follows:-
:-
This invention relates to improvements in self-stopping motions applicable to
machinery for knitting cotton, wool, worsted, silk, and other fibrous substances, and
has for its object that of providing efficient means for automatically stopping the
machine when any desired length of work has been completed, or in case a knot, thick
place or other defect in or on the yarn presents itself to the yarn guide, also when the
yarn breaks, and when the yarn bobbin runs empty, thereby making it impossible to
spoil or damage the fabric being knitted from these causes.
For the purpose of counting or recording the number of stitches or courses and
stopping the machine at any desired point, I provide wheel gear with holes to receive
pins, which operate, according to the setting, on a pivoted lever attached to a friction
pulley or clutch working in conjunction with the driving pulley. The said pivoted
lever is provided with a starting handle and lever suitably mounted on the front side
of the machine, by which it can be stopped or started at will. The end of the pivoted
lever moves on a fixed slide bar with a notch or projection to arrest and maintain the
position of the pivoted lever when the machine is in motion. In case it is desired to
stop the machine by hand it can be performed by operating the starting handle to lift
the pivoted lever from the notch or projection, when it will be actuated by a spring or
its equivalent to release the friction pulley or clutch from the driving pulley. When
the desired number of stitches or courses have been knitted the pin on the wheel gear
operates a lever and catches, and lifts the pivoted lever from the notch or projection
and instantly stops the machine.
For stopping the machine in case of knots, thick places, or other defects in or on the
yarn, also when the yarn breaks, and when the yarn bobbins run empty 1 provide
suitable framework carrying a plate with openings, over which the yarn passes from
the creel bobbins to the yarn guides and needles. On the yarn is supported a bent or
hooked wire, staple, or pin with an eye, with ends extending through the said openings.
Immediately under the openings are disposed two rollers revolving together inwardly;
one roller driving the other by wheels or their equivalents, driven by a band or other
mechanical means from the machine or otherwise. The rollers are so constructed
and mounted that when the yarn breaks or the yarn bobbins run empty the wire,
staple, or pin drops down and is turned through the rollers, which causes one roller
to move so as to permit it to pass through or between them to a receptacle underneath.
Instead of a loose wire, staple, or pin being employed a contrivance can be used to
drop between the said rollers to force them apart to stop the machine, and at the
same time allow of the said contrivance being withdrawn automatically or otherwise.
To the vibrating roller is attached a lever and rod which actuates the before mentioned
pivoted lever from the notch or projection and stops the machine.
In order to stop the machine in case of a knot, thick place, or other defects in or
on the yarn, the wire, staple, or pin is supported by means of a wire or other suitable
contrivance, so that when the knot or uneven yarn comes into contact with the pivoted
yarn guide the latter operates the supporting wire or its equivalent, releases the wire,
staple, or pin, or brings into contact with the revolving rollers and stops the machine
as before described.
The yarn guides can have suitable slots or openings through which the yarn
passes. Immediately a knot or uneven place on or in the yarn presents itself

page_text: the guide vibrates so as to operate the supporting wire or other suitable
contrivance, and to release the knot or uneven part from the slot or opening.
The yarn guides can be fitted with springs or their equivalents to re-set the same.
In order to stop the machine when the yarn breaks on the front side of the
machine we apply a 'connection, between the tension wire or lever that takes up the
slack yarn, to another or to the same wire which supports a bent or hooked wire,
staple, or pin on the slotted plate.
The whole of the apparatus is mounted on suitable framework attached to the
knitting machine in any convenient manner.

Improvements in Self-stopping Motions, Applicable to: Machinery for
Knitting Cotton, Wool, and other Fibrous Substances.
We, WILLIAM HENRY HOYLE and JOHN TAYLOR of the Turton Manufacturing
Company, Turton near Bolton in the County of Lancaster, Hosiery Manufacturers,
do hereby declare the nature of our said invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in self-stopping, motions applicable to
machinery for knitting cotton, wool, worsted, silk, and other fibrous substances, and
has for its object that of providing efficient means for automatically stopping the
machine when any desired length of work has been completed, or in case a knot, thick
place or other defect in or on the yarn presents itself to the yarn guide, also when the
yarn breaks, and when the yarn bobbin runs empty, thereby making it impossible to
spoil or damage the fabric being knitted from these causes.
For the purpose of counting or recording the number of stitches or courses and
stopping the machine at any desired point, we provide wheel gear with holes to
receive pins, which operate, according to the setting, on a pivoted lever attached to a
friction pulley or clutch working in conjunction with the driving pulley. The said
pivoted lever is provided with a starting handle and lever suitably mounted on the
front side of the machine, by which it can be stopped or started at will. The end of
the pivoted lever moves on a fixed slide bar with a notch or projection to arrest and
maintain the position of the pivoted lever when the machine is in motion. In case it
is desired to stop the machine by hand it can be performed by operating the starting
handle to lift the pivoted lever from the notch or projection, when it will be actuated
by a spring or its equivalent to release the friction pulley or clutch from the driving
pulley. When the desired number of stitches or courses have been knitted the pin on
the wheel gear operates a lever and catches, and lifts the pivoted lever from the notch
or projection and instantly stops the machine.
For stopping the machine in case of knots, thick places, or other defects in or on
the yarn,. also when the yarn breaks, and when the yarn bobbins run empty we.
provide suitable framework carrying a plate with openings, over which the yarn passes
from the creel bobbins to the yarn guides and needles. On the yarn is supported a
bent or hooked wire, staple, or pin with an eye, with ends extending through the said
openings. Immediately under the openings are disposed two rollers revolving
together inwardly; one roller driving the other by wheels or their equivalents, driven
by a band or other mechanical means from the machine or otherwise. The rollers
are so constructed and mounted that when the yarn breaks or the yarn bobbins run
empty the wire, staple, or pin drops down and is turned through the rollers, which
causes one roller to move so as to permit it to pass through or between them to a
receptacle underneath.

page_text: To the vibrating roller is attached a lever and rod which actuates the before
mentioned pivoted lever from the notch or projection and stops the machine.
In order to stop the machine in case of a knot, thick, place, or other.defects in or on
the
yarn, the wire, staple, or pin is supported by means of a wire or other suitable
contrivance, so that when the knot or uneven yarn comes into contact with the
pivoted yarn guide the latter operates the supporting wire, or its equivalent, releases
the wire, staple, or pin, and brings into contact with the revolving rollers and stops
the machine as before described.
The yarn guides can have suitable slots or openings through which the yarn passes.
Immediately a knot or uneven place on or in the yarn presents itself the guide
vibrates so as to operate the supporting wire or other suitable contrivance, and to
release the knot or uneven part from the slot or opening. The yarn guides can be
fitted with springs or their equivalents to re-set the same.
In order to stop the machine when the yarn breaks on the front side of the
machine we apply a connection, between the tension wire or lever athat takes up
the slack yarn to another or to the same wire, which supports a, bent, or hooked wire,
staple, or pin on the slotted plate.
The whole of the apparatus is mounted on, suitable, framework attached to the
knitting machine in any convenient manner.

A, A, are frame sides of, the knitting machine; B the framework for carrying, the
needle beds, slide, bars, carriage, driving gear, and, other parts; C the yarn.guides
which slide on the slide bars D by, the action or movement of the carriage; and is
the driving shaft fitted with the driving. pulley, G.
For the purpose of counting or recording the number of stitches, or courses and
stopping, the machine, at any desired point, we mount on, the framework Bithe,spur
wheel I provided, with, the, holes 2, to receive one, or more pins 3. The spurwheel: 1

page_text: is mounted on the centre 4, and is driven by the spur pinion 5 on the wheel 6, both
the latter being mouuted on the centre 7 secured to the framework B. The wheel 6
is driven by the worm 8 on the driving shaft E. The pin or pins 3 operate, according
to the setting of the same, as the spur wheel 1 rotates, on the arm 9 pivoted to the
lever 10, and held in position by the spring 11. The lever 10 is mounted on the
centre 12 in the fixing 13 secured to the framework B by the bolt 14. The other end
of the lever 10 extends to and over the end 17 of the catch 15 pivoted on the
centre 16. The end 18 of the catch 15 extends under the lever 19 pivoted to the
framework B by the pin or centre 20. The lever 19 is attached to the friction
pulley or clutch 21 working in conjunction with the driving pulley G. The friction
pulley or clutch 21 is provided with the sleeve 22 fitted with the spur wheel 23 and
the collar or groove 24 to slide on the driving shaft E. The pin 25 on the end of
the lever 19 operates in the collar or groove 24 to move the friction clutch 21 in or
out of gear with the driving pulley G. The end of the lever 19 moves on the slide 26
attached to the framework B, and is provided with the projection 27, as shown in
Fig. 13, to arrest and maintain the position of the pivoted lever when the machine
is in motion. When the lever 19 is held by the projection 27 as shown in
Figs. 1, 2, 3, and 13 the friction pulley or clutch 21 is in gear with the driving
pulley G, and the machine is in motion provided the pulley G is being driven. The
slide 26 is mounted on the slide bar 28 secured to the framework B. After the
slide 26 has been fixed in position by the setting screw 29 in the slide bar 28 it is
locked by the bolt 30. In case it is desired to stop the machine by hand
it is performed by lifting the handle 31 mounted on the centre 32 in the
fixing 33 secured to the framework B by the bolts 34. The other end of the
handle 31 is provided with the projections 35 and 36, the latter resting under
the lever 19. When the handle 31 is raised the projection 36 lifts the outer end of
the lever 19 above the projection 27, when it assumes the position shown in dotted
lines in Fig. 13 by the action of the spring 37 and releases the friction pulley or
clutch from the driving pulley G and stops the machine. The machine is re-started
by depressing the handle 31, which causes the projection 35 to force the lever 19
back to the position shown in Figs. 2, 3, and 13, and puts the friction pulley or
clutch 21 in gear with the driving pulley G.
When the desired number of stitches or courses have been knitted the pin or pins 3
on the wheel 1 operates the arm 9 and lifts the lever 10, which action causes the
other end of the lever 10 to be depressed and to operate on the end 17 of the
catch 15. By the depressing action of the end 17 of the catch 15 the end 18 lifts
the lever 19 above the projection 27, and allows the spring 37 to release the friction
pulley or clutch 21 from the driving pulley G which instantly stops the machine.
For stopping the machine in case of knots, thick places, or other defects in or on
the yarn, also when the yarn breaks, and when the yarn bobbins run empty we
provide the pillar 40 carrying the table 41 on which are mounted the yarn bobbins 42,
pillar 43, and the plate 44 over which the yarn passes from the yarn bobbins 42 to
the yarn guides C and needles. The yarn is represented by the line 45. On the
yarn 45, in its passage from the bobbins 42 to the yarn guides C and needles, is
supported the bent or hooked wire or staple 46, of the form shown in Figs. 9 and 10,
with the ends 70 extending or projecting through the slot or opening 47 in the
plate 44 as shown in Figs. 4, 5, 6, 7, and 8. If desired the bent or hooked wire or
staple 46 can be substituted with the pin 46 with the eye 49 through which the
yarn 45 passes to support the same. Immediately under the slot or opening 47 are
disposed the rollers 50 and 51 revolving together in the direction indicated by the
arrows. The roller 50 is provided with the centres 52 mounted in the bearings 53 of
the framework 54 on the pillar 43. The roller 51 with its centres 54× is mounted in
the levers 55 pivoted to the framework 54 by the centres 56. The levers 55 are
jointed together at their upper ends by the stay 56× and nuts 57. The roller 50 is
driven from the driving shaft E by the bevel wheels 58 and shafts 59, held or
supported in the fixings 60 secured to the framework in any convenient manner.
the centre 52 is fixed the spur wheel 61 in which gears the spur wheel 62 on the
On

page_text: centre 54* to drive the roller 51. One of the levers 55 is considerably longer than
the other, and extends to a point near the framework B. When the bent or hooked
wire, staple, or the pin is released from the yarn 45, through the yarn breaking or
the yarn bobbins running empty, it drops down and through the slot or opening 47,
and is turned through or between the rollers 50 and 51 as shown in Fig. 6. This
causes the roller 51 to be moved sideways bodily and pushes the long end of the
lever 55 sufficiently to lift the lever 19 above the projection 27 by the inclined or
wedge shaped slide 63. The latter is mounted in the slide bar 64' secured to the
framework B as shown in Fig. 14. The slide 63 is provided with the arm 65 to
attach it to the long end of the lever 55 by means of the connecting rod 66 and pins
or centres 67. After the bent or hooked wire, staple, or pin has passed between the
rollers 50 and 51 it drops into the receptacle 68 underneath. Immediately the
lever 19 is lifted above the projection 27 it is operated by the spring 37 and releases
the friction pulley or clutch 21 from the driving pulley, G.
For the purpose of stopping the machine in case of a knot, thick place, or other
defects in or on the yarn 45 the wire, staple, or pin is supported on the wire 71
coupled to the pivoted yarn guide 72 by the rod or wire arm 73 as shown in Figs. 4
and 5. The wire support. 71 slides through the guide 74 secured to the plate 44.
The yarn guides 72 are pivoted to the plate 44 by the pins 74*. The yarn guides 72
are constructed in two segments, one being fixed to the plate 44, and the other being
mounted loosely on the centre 74* to allow of the segment moving sideways in case
a knot or thick place in or on the yarn presents itself as shown in Fig. 7, by which
the wire, staple, or pin 46 is released from its supporting wire 71. When the bent
or hooked wire, staple, or pin is released from its supporting wire 71 it drops
between the rollers 50 and 51 and operates the stopping mechanism of the machine as
before described. The vibrating yarn guides 72 are fitted with the springs 75 to
re-set the same after the defect has been removed.
In order to stop the machine when the yarn breaks on the front side of the
machine we provide the tension lever 76, that takes up the slack yarn, with the
arm 77 coupled to the wire 71 employed to support the bent or hooked wire, staple,
or pin 16 as shown in Figs. 5 and 8. The lever 76 is provided with the lever 78 and
balance weight 79 for the purpose of allowing of the free movement of the lever 76
according to the tension on the yarn. Immediately the yarn breaks the balance
weight 79 drops and releases the wire 71 from the bent or hooked wire, staple, or
pin 46, which drops into contact with the rollers 50 and 51 and stops the machine as
before described.
In another modification the supporting wire 71 can be provided with the taper or
inclined end 80 as shown in Fig. 15. The bent or hooked wire, staple, or pin 46 is
supported on the taper or inclined end 80 above the rollers 50 and 51, which,
immediately the wire 71 is operated by a knot, thick place, or other defects in or on
the yarn, or by the yarn breaking, or by the yarn bobbins running empty, drops
between the said rollers and forces them apart as shown in Fig. 16. When the
rollers 50 and 51 are forced apart the machine is stopped by the intervening
mechanism before described. In this case the bent or hooked wire, staple, or pin 46
is held between the rollers 50 and 51 until the wire 71 is re-set; the latter action
withdrawing the same automatically from between the said rollers, at which point it
will remain until the wire 71 is operated by any of the aforesaid defects or causes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we would have it understood
that we lay no claim to the driving shaft E, pulley G, friction pulley or clutch 21,
spur wheel 1 with the holes 2, pins 3, pinion 5, wheel 6, worm 8, arm 9, and
spring 11, but what we claim is :-
1. The combination and arrangement of the lever 10, catch 15, lever 19, spring 37,
adjustable slide 26 with the projection 27, handle 31 with the projections 35 and 36,
substantially as described and shown for the purpose specified.

page_text: 2. Stopping a knitting machine by means of a metallic wire, staple, or pin,
dropping between two revolving rollers to force them apart.
