PROVISIONAL SPECIFICATION left by the said Henry Warner,
Joseph Haywood, and William Cross at the Office of the Comi-
missioners of Patents, with their Petition, on the 7th May 1853.
We, HENRY WARNER, Manufacturer. JOSEPH HAYWOOD and
WILLIAM CROSS, Mechanists, of Loughborough, do hereby declare the
nature of the Invention of "IMPROVEMENTS IN MACHINERY USED IN THE
MANUFACTURE OF FRAMEWORK KNITTING" to be as follows:---
This Invention consists, first, of applying to knitting machines appa-
ratus for stopping the same when thread is not laid on to the needles.
The machine goes on working by power so long as thread is correctly
laid on to the needles. but immediately the thread is broken or not

page_text: laid correctly on to the needles, a lever or instrument is released, and
moves away from another lever or instrument which comes in the way
of a ratchet wheel, and is moved thereby, and by its movement acts on
the belt fork, and moves the belt from the fast on to the loose pulley.
And secondly, the Invention consists of applying apparatus for
stopping a knitting frame when a determined length of fabric has been
produced, and this is done by means of count wheels, which are caused
to rotate by the working of the machine, and when the requisite length
has been made the lever before mentioned is released, and the belt is
moved from the fast to the loose pulley.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Warner, Joseph Haywood, and William
Cross in the Great Seal Patent Office, on the 7th November
1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
HENRY WARNER, Manufacturer, JOSEPH HAYWOOD and WILLIAM CROSS
Mechanists, of Loughborough, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of May, in the year of
our Lord One thousand cight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Henry Warner, Joseph Haywood, and
William Cross, Her special licence that we, the said Henry Warner,
Joseph Haywood, and William Cross, our executors, administrators,
and assigns, or such others as we, the said Henry Warner, Joseph
Haywood, and William Cross, our executors, administrators, and
assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY

page_text: USED IN THE MANUFACTURE OF FRAMEWORK KNITTING," upon the condition
(amongst others) that we, the said Henry Warner, Joseph Haywood,
and William Cross, by an instrument in writing under our bands
and scals, or under the hand and seal of one of us, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Henry Warner, Joseph
Haywood, and William Cross, do hereby declare the nature of the said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement
thereof, that is to say:
This Invention consists, first, of applying to knitting machines
apparatus for stopping the same when thread is not laid on to the
neelles. The machine goes on working by power so long as thread is
correctly laid on to the needles, but immediately the thread is broken
or not laid correctly on to the needles a lever or instrument is released,
and moves away from another lever or instrument which comes in the
way of a ratchet wheel, and is moved thereby, and by its movement
acts on the belt fork, and moves the belt from the fast ou to the loose
pulley.
And secondly, the Invention consists of applying apparatus for
stopping a knitting frame when a determined length of fabric has been
produced, and this is done by means of count wheels, which are caused
to rotate by the working of the machine, and when the requisito length
has been made the lever before mentioned is released, and the belt is
moved from the fast to the loose pulley.
Having thus stated the nature of our Invention, we will proceed to
give a more detailed account thereof, and in doing so we will refer
to the accompanying Drawings, in the various Figures of which the
same letters denote similar parts.
Figure 1, is a section. Figure 2, an end elevation. Figure 3, a
front view, and Figure 4, a plan drawn full size of so much of a frame-

page_text: work knitting machine, having our Invention applied thereto, as will
enable us to describe the manner of applying our Invention thereto.
a. a, is the framing of the machine; b, is the driving shaft with fast
and loose pullies c, c¹; d, is a pinion (keyed on the driving shaft or
axis b.) taking into and driving the toothed wheel e, on the cam shaftf.
On the shaft f, is a cam g, which gives the requisite movement to the
several parts used by us in carrying out our Invention. h, is a lever
having thercon a projection h³, on which projection the cam g, acts in
order to raise the lever h. Through an opening or eye at the outer
end of the lever h, is passed one end of a rod i. Around the rod i, is
applied a spiral spring ), which is so placed that by the rising of the
outer end of the lever h, the spring j, is pressed upwards against the
collar or stop, which is on the rod i, by which means the rod i,
will be slightly raised. The upper end of the rod i, is connected to
the short lever k, on the axis 7; hence, by raising the rod i, the instru-
ments or pressers m, m, are caused to act on the various threads
passing from the bobbins to the thread carriers, so as to press them on
to the plates or pieces of metal », n, affixed to the wooden bar o; as
the lever, continues to rise, and by rising has caused the compression
of the spring j, and has given movement to the pressing instruments
m, m, the pin or projection I, of the lever h, acts upon the connecting
link p. The link p, is provided with a slot or opening p', into which
the pin or projection h², of the lever h, enters, and this slot or opening ',
allows of the necessary movement to the pressers m, m, and parts
connected therewith, taking place without the rod i, being completely
raised until after the pin or projection h2, of the lever h, has arrived at
the upper part of the slot or opening p', when the rod or link p, will be
raised as well as the rod i. The link p, is connected to the spindle bar
or axis q, by the arm or lever r; motion is thus communicated to the
arms or levers s, s, (fixed to the spindle bar 9,) which carry the instru-
ments t, t, which move on pins or centres at the ends of the arms s.
The outer ends of the instruments t, at their cranked parts, are
pressed on by the threads, and so long as the threads are unbroken the
machine will go on working. At the lower ends of the instruments (1,

page_text: are catches u, u. Whenever a thread breaks one of the instruments t, t,
becomes thereby released from the pressure of the thread, and that
instrument t, will assume the position shown by the dotted lines in
Figure 1. By this arrangement of parts, when the instruments t,-are
again raised by the lever h, the instrument t, where such thread has
broken, will take hold by its catch u, of one of the levers v, by which it
will be raised, and the spindle bar or axis'v', will be turned partly
round. At one end of the spindle bar or axis v', is fixed an armi or
lever see Figure 2. The end of the arm, is connected to a bell
crank lever, by the link ; the bell crank v³, works on a.centre.or
axis v. On the lower end of the bell crank v³, is a catch v³, which
sustains that end of the frame a', which is carried by the axis a³,-from
being borne down by the action of the spring w, attached to. the ground
or flooring; but when a thread has broken and the arm v, is afterwards
raised, the arm or lever, will also be raised, and the catch, of the bell
crank will be thereby moved from under the end of. the frame a', 'thus
allowing that end of the frame a', to descend slightly by the action of the
spring at w, whereby the clawkera, will descend and fall into. the teeth.of
the wheel, on the shaft or axis b. The end a¹, of the clawker is cut
obliquely, so that by its coming in contact with the enda, of the levera³,
that end of the lever will be pressed outwards; and as the. lever a³,
moves on its axis as, the other end, will be moved inwards, and push
in advance of it the rod y, which slides in its bearings a², ², fixed to
the framing a, a. The forky, on the rod y, embraces the driving
baud; hence the movement of the rod y, causes the band to leave the
fast pulley c, and to pass on to the loose one-c, and thus stop the
working of the machine. When the broken thread has been 'repaired
the rod y, is to be brought back again, and such is to be the case in
regard to the end of the frame a, and clawker a, carried thereby, to
allow of the. catch 6, of the bell crank to assume, its former. position;
the parts will then be ready to operate again as before. The several
threads pass from their hobbins over the guides (1,) 1,) see Figure.I,
through the holes in the guides (2.) 2.) then under the guides (3,)*3,)
thence between the nippers m. m. over the cranked parts of the

page_text: instruments t, t, through the guides (4,) 4.) and (5,) 5,) to the thread
carriers (6,). 6.) as shewn by Figures 1, and 4; and by the thread
carriers the threads are laid on to the needles by any of the well-known
methods.
Figures 5 and 6, respectively show a front view and section, half size
of apparatus, for stopping the machine whenever a thread breaks,
having some of its parts different from the apparatus above described.
Instead of using a clawker æ, to act on a ratchet wheel, we employ a
break or friction lever R, which acts upon the periphery of the fly
wheel L. For this purpose L, is a lever, working on an axis at M.
N, is a catch on one end of a bell crank lever O, which turns on an
axis O'. The other end of the bell crank O, is connected to the lever v²,
before described; the hinder portion of the lever L, is turned up, and
forms a lever L', which, when the removal of the catch N, takes place
by the breaking of a thread, as before described, the lever L, descends
by the action of the spring S, and the portion L', of the lever L, pushes
in advance of it the stud or projection P, on the bar P. To the other
end of the bar P, is connected the fork P, which embraces the driving
band or strap. The lever L, on its descent, comes in contact with the
end Q, of the lever Q, thereby causing it to move on its axis, and
press away the other end Q, of the lever Q, by which the break R,
was supported or held; so that the break R, being hinged at R',
descends upon the periphery of the fly wheel I, aided by the lever I',
on the centro I, and the spring S, attached to the lever L, and to
the ground or flooring. When the broken thread has been repaired,
the lever I, is again to be drawn up, and the catch N, placed beneath
it, and the end Q, of the lever Q, is again to be made to bear the
break R, lever I³, and the resistance of the spring St.
We will now proceed to describe the second part of our Invention,
which consists of the employment of apparatus in connection with
framework knitting machinery for stopping the same when a deter-
nined length of work has been produced.
Figure 7, is a front view, and Figure 8, an edge view, of apparatus
suitably arranged for carrying out this part of our Invention. A, is a

page_text: lever working on a centre at A', and having a regulating screw A, the
end of which coming against the stop A", causes a greater or lesser
amount of movement to be imparted to the lever A, by the lever and
cam a, a, hereafter described,) as the screw A², is worked round to
the right hand or to the left. he lever A, carries a pall or click B,
which enters between the teeth of the ratchet C, and is kept in contact
therewith by the spring D, so that each revolution of the cani a', on the
shaft b, (shown in Figure 7,) gives an amount of motion to the rod a',
and lever A, by which the ratchet wheel C, will be caused to move
round on its centre C', one step or tooth in the direction of the arrow.
On the face of the ratchet C, is a pin or tooth C, which enters the
spaces between the teeth of the larger ratchet wheel E, and causes it to
advance one tooth for every revolution of the smaller ratchet wheel C.
The ratchet wheel E, works on an axis E. Upon the boss of the
ratchet E, is an indicator or pointer F, having a collar F, and set
Screw, by which it may be fixed, so as to cause the machine to stop
at any point or length of material produced. G, is a pall which
regulates the movement of the ratchet wheel C; and H, is a pall
which regulates the movement of the ratchet wheel E. I, is a lever
working on a centre at I, having an eye or opening, to which a cord K,
is attached, passing over the pullics j, j (shewn in Figure 2,) in such
manner that upon the indicating point F, coming against the tooth or
projection I, of the lever I, the end of the lever to which the cord K,
is attached will be raised, and draw up the lever, and stop the
machine, as shown and described in reference to the Figures 1, 2, 3, 4.
Having thus described the nature of our Invention, and the manner
of performing the same, we wish it to be understood that we make no
claim to any of the parts separately, nor do we confine ourselves to the
precise details herein shewn and described, as the same may he varied
without departing from our Invention. But what we claim is,--First,
the combining with framework knitting machines apparatus for causing
such machines to stop in the event of a thread breaking or failing to be
properly supplied.
Second, we claim the employment of apparatus in combination with

page_text: amework knitting machinery, in order to cause the machinery to stop
hen a given quantity of work has been produced.
In witness whereof, we, the said Henry Warner, Joseph Hay-
wood, and William Cross, have hereunto set our hands and
seals, this Fifth day of November, in the year of our Lord
One thousand eight hundred and fifty-three.
