Year: 1854

page_text: LETTERS PATENT to Henry Warner, of Loughborough, Manufacturer,
and Joseph Haywood and William Cross, of the same place, Mechanists,
for the Invention of "IMPROVEMENTS IN KNITTING MACHINERY.
PROVISIONAL SPECIFICATION left by the said Henry Warner, Joseph
Haywood, and William Cross at the Oflice of the Commissioners of
Patents, with their Petition, on the 10th February 1854.
WC, HENRY WARNER, of Loughborough, Manufacturer, and JOSEPH HAY-
WOOD and WILLIAM CROSS, of the same place, Mechanists, do hereby declare
the nature of the Invention for "IMPROVEMENTS IN KNITTING MACHINERY" to be
as follows:-
Heretofore in knitting machinery the jack sinkers have been so formed and
worked that they (having sunk the thread between the needles) have together
with the lead sinkers conjointly worked the course. Now the present im-
provements have for their objects so to construct and arrange the machinery,
that the jack sinkers shall simply perform the process of sinking the thread
between the needles, and that the needles together with stationary lead sinkers
shall work the course. For this purpose the machine is arranged with as
many lead sinkers as there are needles. The lead sinkers are stationary, and.
they carry the presser which passes through them. The needle bar moves
back to bring the new loops into the beards of the needles, the new loops

page_text: being forced under the beards by nebs of the lead sinkers, and the work is
knocked over by the lead sinkers. The jack sinkers in the present Invention
perform no part of the working of the course after sinking the thread. The
jack sinkers are either made to slide in guides and separate from the jacks, or
they are fixed to the ends of the jacks and move up and down with them. The
working parts of the jack sinkers and lead sinkers are modified in their shapes
to accommodate them to these movements. The needle bar moves to and fro
from front to back, and has a rocking motion, in order to bring the work under
the arches of the lead sinkers.
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 10th August 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
WARNER, of Loughborough, Manufacturer, and JOSEPH HAYWOOD and WIL-
LIAM CROSS, of the same place, Mechanists, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of February, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth 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 KNITTING MACHINERY," upon the condition
(amongst others) that we, the said Henry Warner, Joseph Haywood, and
William Cross, or one of us, by an instrument in writing under our hands
and seals, 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.

page_text: NOW KNOW YE, that I, the said Henry Warner, 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:-
Heretofore in knitting machinery the jack sinkers have been so formed and
worked that they (having sunk the thread between the needles) have together
with the lead sinkers conjointly worked the course. Now the present im-
provements have for their objects so to construct and arrange the machinery
that the jack sinkers shall simply perform the process of sinking the thread
between the needles, and that the needles together with stationary lead sinkers
shall work the course. For this purpose the machine is arranged with as
many lead sinkers as there are needles. The lead sinkers are stationary, and
they carry the presser which passes through them. The needle bar moves
back to bring the new loops into the beards of the needles, the new loops
being forced under the beards by the nebs of the lead sinkers, and the work
is knocked over by the lead sinkers. The jack sinkers in the present
Invention performing no part of the working of the course after sinking the
thread. The jack sinkers are either made to slide in guides and separate
from the jacks, or they are fixed to the ends of the jacks and move up and
down with them. The working parts of the jack sinkers and lead sinkers
are modified in their shapes to accommodate them to these movements. The
needle bar moves to and fro from front to back, and has a rocking motion,
in order to bring the work under the arches of the lead sinkers.
Having thus stated the nature of our Invention, we will proceed to describe
the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a transverse section of the principal working parts (drawn
full size) of a machine constructed according to our Invention; and Figure 2
shows a transverse section of the machine ou a reduced scale to show the
mode of giving motion to the various principal parts; the other Drawings
show some of the parts separately, the nature of which being written thereon
it will not be necessary to give a more detailed description. It may be
remarked that it will facilitate a workman carrying out these improvements if
at the outset he clearly understands that the jack sinkers do not in this
machinery contribute in working out the "course" after they have as hereto-
fore at the commencement sunk the thread over the pairs of needles, but that
the lead sinkers, which are as numerous as the needles, come into action
immediately after the jack sinkers have performed their part, and divide the

page_text: thread between all the needles, and by the joint action of the lead sinkers and
the movement of the needle bar the "course" is completed without the
further aid of the jack sinkers. a, a, are the jack sinkers (one to every two
needles), which are constantly pressed downwards by the springs a', a', fixed
to the bar a², supported by the end framing of the machine; the jack sinkers
a, a, (in this arrangement) slide in combs a³, at, fixed to the bar a, which is
fixed to and supported by the end framings of the machine; b, b, are the lead
sinkers, cast in leads and fixed to the sinker bar b', which is fixed to and
supported by the end framings of the machine, and there are as many lead
sinkers as there are needles, every alternate sinker having a projecting neb b
formed thereon, which acts to divide the loop previously made over every two
needles by the jack sinkers a, when the needles c, c, are drawn back by the
movement of the needle bar c. Motion is given to the needle bar in the
following manner-d is a cam fixed on the cam shaft or axis d', which by
acting on the truck or roller d gives motion to the lever d³. This lever d³ is
supported at one end by the axis e¹, and its other end is connected to the
needle bar c by the link d', so as to raise and lower the needle bar at each
revolution of the cam shaft; e is a cam fixed on the cam shaft, which acts on
the truck or roller &, carried by the lever arm e³, fixed on the spindle bar
el, which gives motion to lever arms e, which are connected by arms or
links to the needle bar, so as to move the needle bar to and fro; f is the
slur cock bar supported in front of the jack sinkers a, and f¹ is the slur cock,
the construction of which is shown separately in the other Figures, in order to
show the sliding piece f, which lifts up and supports the jacks during the
passage of the thread carrier, the double incline f acting under the projecting
part a* of the jacks to raise them above the needles. Motion is communi-
cated to the slur cock in the following manner :-g is a crank fixed on the end
of the axis h, which receives motion from the cam shaft d' by a bevil pinion ¹
taking into and driving the bevil wheel fixed on the axis h. The crank g
is connected by pin joints to the links g', g', which are supported at their other
ends by links g², suspended by pin joints from the cross bar g', the links g¹, g',
are connected to one end of the links g', g, to which the lever g' is connected
by a pin passing through slots in the ends of the links g³, the lower end of
the lever g' moving on a stud 9, and the upper is connected with the cord
or band g, which passes partly round the pullies 9', the ends of the cord
being connected to the slur cock f', so as to move it from end to end of the
machine by the alternate to and fro movement of the lever g'; i is a wheel
fixed on the cam shaft or axis, which receives motion by the toothed-wheel i
taking into the teeth of the wheel j fixed on the axis k, to which motion may

page_text: be communicated by a steam engine or other motive power. Figure 3 shows
a section of another arrangement or modification of some of the parts, in which
the jacks have sinkers a affixed to them, and they move up and down on axes
in place of sliding in guides or combs; in other respects they simply act to
form the loop as before described, the lead sinkers being formed with nebs to
divide the loop, as in Figure 1.
Having thus described the nature of our Invention, and the manner of
performing the same, we would have it understood that we do not claim the
parts separately, nor do we confine ourselves to the precise details herein
described, so long as the peculiar character of our Invention be retained.
But what we claim is, the combination of parts of knitting machinery whereby
jack sinkers are so constructed and worked as simply to form loops between
alternate pairs of needles, lead sinkers (one to each needle) acting together,
with a moveable needle bar dividing the loops (made by the jack sinkers)
between all the needles and completing the "course," as described.
In witness whereof, I, the said Henry Warner, have hereunto set my hand
and seal, this Fourth day of August, in the year of our Lord One
thousand eight hundred and fifty-four.
