We JOHN HOWARD STOTT of Baron Street Rochdale in the County of Lancaster
Machine Maker and АMOS GRIMSHAW of Albion Terrace Littleborough in the County
of Lancaster Hosiery Manufacturer do hereby declare the nature of this invention to
be as follows:-
Our invention refers to such knitting machines as are actuated by "power" and
relates to arrangements for arresting the operation of such knitting machines when
the yarn or thread being knitted contains a knot or becomes broken or absent.
According to our invention we actuate a knitting machine or knitting machines by
means of a shaft which shaft is provided with suitable gearing by means of which it
imparts motion to the machine or machines above mentioned-Upon the shaft aforesaid
are the two portions of a clutch one portion of which clutch is secured to the said
shaft the other portion of such clutch being capable of being slidden upon the said
shaft by means of a spring-The loose portion of the clutch above mentioned is
provided with a pulley which receives rotary motion by means of a strap or by any
other suitable means from any source of motive power.-Supported by and capable of
being rotated in a suitable frame-work is a roller fast upon which roller is a pulley
which by means of a band or strap receives rotary motion from any source of motive
power-Secured to suitable frame-work are studs upon which is mounted a frame
carrying a roller which at times is by means of a spring or weight held against the
roller before mentioned-Upon a bar or studs secured to the framework above
mentioned and capable of being turned thereon is an arm or frame-A projecting arm
upon the said arm or frame extends across and above slots between bars secured to the
framework above referred to-We form the projecting arm above mentioned with an eye
at one end and with a projection at the remaining end-We provide an arm and
projecting part for each of the knitting machines to which our invention is applied-
The yarn or thread supplied to each of the knitting machines before mentioned is
passed through the eye formed in the arm aforesaid and then through the guides
ordinarily employed in conjunction with knitting machines. We pass over the yarn or
thread a piece of wire bent into the form of an U inverted or into any other suitable

page_text: form the ends or an end of which piece of wire pass or passes into one of the slots
between the bars previously mentioned. We also hang a bent wire similar to that
above mentioned upon the projection formed upon the projecting arm above referred
to If the yarn or thread passing to the knitting machine contains a knot such knot
arriving against the edges of the eye above mentioned and not being capable of
passing through the said eye draws forward the projecting arm and removes the
projection upon the said projecting arm from beneath the bent wire hung thereon-
The said bent wire being then no longer supported falls between the rollers previously
mentioned thereby causing the roller carried by the frame above referred to, to be
moved away from the other roller and by means of a projection on the said frame
liberate a catch thereby allowing the loose portion of the clutch before mentioned to
be separated from the other portion of such clutch, so that the motion of the knitting
machine will be arrested-In case the yarn or thread supplied to the knitting machine
becomes broken or absent the bent wire previously supported thereby will fall between
the rollers before mentioned and cause such rollers to become separated the separation
of the rollers causing the catch above mentioned to move so that the two portions of
the clutch may become separated.
In some cases we connect the arm carrying the eye and projection used in con-
junction with one knitting machine to the arm carrying the eye and projection used in
conjunction with another knitting machine.
We employ a spring in conjunction with the arm carrying the eye and projection
above mentioned to prevent such arm or lever from straining the yarn or thread when
drawn forward by a knot upon the said yarn or thread.
We provide the rollers above mentioned with a guard or cover to prevent the yarn
or thread when broken or severed from becoming wrapped around such rollers-We also
place a tray or other receptacle beneath the rollers before mentioned to receive the
bent wires after such bent wires have passed between the said rollers.
By our invention we enable one attendant to attend to two or more knitting
machines.
We provide the frame carrying the roller before referred to with a suitable bar or
handle by means of which the said roller and certain of the parts may be placed in
position for again "starting" the knitting machine or knitting machines.
In another arrangement of our invention we employ a weight which becomes
liberated when the yarn or thread becomes broken or absent.
The said weight when liberated liberates a catch so as to allow the spring of the
clutch to separate the two portions of the clutch so as to stop the knitting machine
or knitting machines-In some cases we also cause a knot, when such is contained in
the yarn or thread, to liberate the weight above referred to or another weight to stop
the knitting machine or knitting machines.

page_text: Improvements Applicable to Certain Knitting Machines.
We JOHN HOWARD STOTT of Baron Street Rochdale in the County of Lancaster
Machine Maker and AMOS GRIMSHAW of Albion Terrace Littleborough in the
County of Lancaster Hosiery Manufacturer 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 refers to such knitting machines as are actuated by "power" and
relates to arrangements for arresting the operation of such knitting machines when
the yarn or thread being knitted contains a knot or becomes broken or absent.
We will in the first instance describe our invention as applied to and used in
conjunction with a "straight" knitting machine.
In the drawings hereunto annexed Fig. 1 is a front elevation, Fig. 2 a plan from
which certain parts are omitted to avoid confusion, Fig. 3 an end elevation and Fig. 4
a vertical section taken on the line A B of Fig. 1-Fig. 5 is a plan and Fig. 6 an
elevation upon a larger scale of a portion of that which is shown in Figs. 1. 2. 3.
and 4-The same letters of reference are applied to corresponding parts throughout
the whole series of figures.
a is a bench or table to which a straight knitting machine C of ordinary construction
is secured. Fast upon the shaft of the knitting machine upon which is mounted
the handle c by which the machine may be turned by hand we mount a bevel-wheel d
the teeth of which "
gear with
the teeth of a bevel-wheel e fast upon a shaft f
supported by and capable of being rotated in brackets g secured to the bench or
table a by means of bolts and nuts-Upon the shaft fare mounted the two portions h¹ h³
of a clutch the portion 2 of which clutch h is secured to the shaft f-The portion h¹
of the clutch h is capable of being slidden longitudinally upon the shaft -The loose
portion of the clutch h is provided with a pulley 3-Secured to the bench or
table a are end-frames j. j-k is a roller the axle ¹ of which is supported by and
capable of being rotated in bearings formed in the end-frames j. j-Fast upon the
axle k¹ of the roller k is a pulley which by means of a band or strap receives
rotary motion from any source of motive-power-Secured to the end-frames j. j
respectively are studs, Upon the studs and capable of being turned thereon
is mounted a frame which frame carries a roller m free to be revolved therein――
The frame is provided with an arm the lower portion of which is bent so as to
be parallel to the front of the machine C-Secured to one of the end-frames j. j is a
bracket n to which is secured one end of a spring o the other end of which is formed
into a handle o-In the bracket n we form a notch or recess n¹-The spring o is so
formed that while tending to force the handle o¹ into the notch or recess n¹ it also
tends to force the handle o' in the direction indicated by the arrow D-The handle o'
also pressing against the portion of the arm tends to force the roller m against
the roller k-Mounted upon the roller k is a toothed wheel the teeth of which
46 gear with " the teeth of a wheel m' mounted upon the roller m-Secured to the bench
or table a is a bracket p provided with a stud p¹ upon which and capable of being
turned thereon is a lever q one end of which is formed as a handle g¹ the other end
of such lever q being at times acted upon by the handle o―The lever is provided
with a pin q which passes into a groove formed around the boss of the portion /¹
of the clutch -Carried by the end-frames i, j, is a bar r and secured to such bar r
is an arm s-A projecting arm s' secured to the arm s extends across and above slots t,

page_text: between bars t¹ which bars t¹ are supported by the ends of such bars t¹ passing into
recesses formed in the end-frames j. j-Secured to the arm s¹ is a projecting parts
The arm s is provided with a projecting part s which resting upon the stay bar
maintains the arms in the position in which it is shown-The yarn or thread E
supplied to the knitting machine C is passed through an eye s formed in the arm s
and then through the guides Cordinarily employed in conjunction with knitting-
machines At the point where the yarn or thread E passes across the bars t¹ we
hang upon such yarn or thread E a piece u of wire formed as shown in Figs. 7 and 8
the legs u¹ of such piece of wire being passed down either of the slots & between the
bars and such piece u of wire being prevented from passing through the said slot t
by the curved portion u² of such piece u of wire resting upon the yarn or thread E-
We also hang upon the stud s³ a piece u of wire of the form shown in Figs. 7 and 8-
The ends u¹ of such piece of wire being passed down either of the slots t between the
bars t. F is a band or strap which imparts rotary motion to the rollers k, m. In
the position of the parts as shown in the drawings the roller k is rotating in the
direction indicated by the arrow G and by means of the wheels k³, m¹ is rotating the
roller m.
The shaft is also being rotated by means of the strap or band F¹ which
passes around the pulleys ³ ³ and by means of the clutch and wheels e d is causing
the shaft b of the knitting-machine C to be rotated-The yarn, or thread E supplied
to the knitting machine will be passing in the direction indicated by the arrow H-
In case the yarn or thread passing to the knitting-machine C should contain a knot
such knot arriving against the edge of the eyes formed in the arms and being
incapable of passing through the eyes, the arms will be drawn forward by the knot
in the direction indicated by the arrow J-The movement of the arms in such
direction will carry the projecting part 2 from beneath the wire u previously
supported thereby which being unsupported will fall between the rollers k, mn, thereby
causing the roller m to be moved away from the roller k-The movement of the
roller m will cause the frame to be turned upon the studs j¹ in the direction indicated
by the arrow K-The movement of the frame in the direction indicated by the
arrow K will cause the portion 12 to push the handle o¹ out of the notch or recess n¹-
The handle o will then act against the lever q so as to turn it upon the stud p¹ in the
direction indicated by the arrow L and thereby slide the portion ¹ of the clutch
until the teeth on such portion h' are clear of the teeth on the portion h³ when the
portion h² of the clutch / being no longer driven the shaft will be no longer rotated
and the knitting machine C will be "stopped "When the knot upon the yarn or
thread arrives against the edge of the eyes the said knot will turn the arms in the
direction indicated by the arrow J until the knitting machine C is stopped the arm's
being free to be moved by the yarn or thread until the knitting machine (is stopped
no injurious strain is put upon the yarn or thread or upon the knitting machine C.
The attendant having removed the knot from the yarn or thread E turns back the
arms into the position in which it is shown in the drawings and again places the
wire u upon the projecting part 2 as previously described-The roller m is placed
against the roller k by means of the handle -The attendant then places the handle o¹
in the notch or recess n'-The attendant turns the handle q' so as to place the portion h¹
of the clutch into gear with the other portion 2 of the clutch and so cause the
knitting machine C to be again started so that Knitting will proceed.
66
In those cases in which the yarn or thread E being supplied to the knitting
machine becomes broken or absent the wire u previously supported by the yarn or
thread E will fall between the rollers k. m thereby moving the roller m from the
roller and causing the arm to force the handle o¹ from the notch n¹ and thereby
stop" the knitting machine C in a manner similar to that above described-After.
the yarn or thread has been pieced the attendant replaces the parts into the positions
in which they are shewn in the drawing and again places the piece of wire u upon
the yarn or thread E and causes the knitting machine C to be again started-We
provide the roller m with a guard or cover formed of a strip of cloth secured by its
upper edge to one of the bars t'-The guard or cover is shown broken in order that
other parts may be more readily seen- -To the lower edge of the said strip of cloth

page_text: we secure a bar vl which bar ol by its weight keeps the cloth extended-The guard or
cover prevents the yarn or thread when broken or severed from becoming wrapped
around the rollers k, m-Beneath the rollers k, m and secured to the end frames j. j.
we place a trough or receptacle w to receive the wires u after they have passed
between the rollers k. m. When the portion h¹ of the clutch h is removed out of
gear with the other portion of the clutch / the knitting machine C may be worked
by means of the handle c in the ordinary manner.
-
Fig. 9. is an elevation and Fig. 10 a plan showing our invention as employed in
conjunction with knitting machines of the kind known as circular knitting machines―
To the bench or table a is secured the circular knitting machine C-Secured to the
bench or table a by a bolt is a bracket 9 supported by and capable of being revolved
in which is a shaft the other end of which is supported by and capable of being
rotated in a bracket secured to the knitting machine C. Fast upon the shaft f is a
bevel-wheel e¹ which "gears into" the bevel wheel d' of the knitting machine C-
Fast upon the shaft is a pulley provided with a handle c-Fast upon the shaft fis
one portion of a clutch h-Mounted upon the shaft f and loose thereon is the other
portion h¹ of the clutch -As the operation of the various parts of this arrangement
of our invention is the same as that of the parts previously described in reference to
Figs. 1. 2. 3. 4. 5. 6. 7. and 8. and as we have affixed to the various parts in Figs. 9
and 10 the same letters of reference as we have applied to the corresponding parts
in Figs. 1. 2. 3. 4. 5. 6. 7. and 8 no further description of the arrangement shown in
Figs. 9 and 10 will be necessary.
By our invention we enable one attendant to attend to two or more knitting
machines.
We would have it understood that in using the word "knot" we refer to the knots
lumps "snarls" and tangled portions which occur in yarn or thread.
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 herein before described arrangements of apparatus constructed, arranged,
employed, and operating substantially as hereinbefore described by means of which
a knitting machine is stopped when the yarn or thread being knitted by such machine
contains a knot or becomes broken or absent.
