IMPROVED APPARATUS APPLICABLE TO KNITTING MACHINES
Year: 1884

page_text: I, WILLIAM WHITE, Machinist, in the employment of Alfred Chamberlin and
Company, of Newark Street, Leicester in the county of Leicester, Hosiery
Manufacturers, do hereby declare the nature of my invention for "IMPROVED
APPARATUS APPLICABLE TO KNITTING MACHINES," to be as follows:-
Heretofore when commencing to make knitted fabrics on knitting machines, to
" set on
"the attendant has taken a length of yarn, and formed a series of coils
with it, over the whole breadth of needles in each division, each coil enclosing two
or more needles. This I propose to effect on cach separate breadth of needles, or
set of points of equal breadth, the whole width of the machine, simultaneously by
apparatus consisting of the following parts. To each division of the machine,
I attach either a slotted or capped bearing, these bearings carry a bar, which rocks
and slides in them, this bar is provided with as many thread guides as there are
widths of needles in the machine, at one end of the bar, there are a number of
projecting studs, each the width of two or more needles apart, the whole number
being equal to the width of one set of needles, the two outermost studs, clip the
rim of a cam which is slotted in one part, so as to allow one of the studs to pass
through it, at each revolution, the cam rim is of such shape, that it causes the bar
to slide to and fro in its bearings; by the side of the cam there is either an
eccentric or double throw cam, which operates a link or links, so as to cause the
studded and thread guide rod, to rock and pass each guide up through the needles
or points, then down through other needles or points, after being traversed by the
cam first named. Both cams are revolved simultaneously by the attendant, by
means of a handle, projecting from the outerside, at each revolution the whole of
the thread guides pass their yarn up through the needles, or points, then traverse
it over two or more needles, down through the needles, or points, under them, and
up through them the next revolution, the movements being repeated until the yarn
is linked over the whole breadth of needles, or points, thereby producing a perfect,
regular "set on," at the commencement of making either hose, half hose, shirts,
pants or other knitted articles, at a considerable greater speed than can be effected
by hand. Or by applying my improved apparatus to any number of widths of
transferring points, in bars, each such width of transferring points can, be taken
(with the "set on upon them) and transferred to an equal width of needles, in
any machine away from the apparatus.

Company of Newarke Street Leicester in the County of Leicester Hosiery
Manufacturers do hereby declare the nature of my invention for IMPROVED
APPARATUS APPLICABLE TO KNITTING MACHINES and in what manner the same
is to be performed, to be particularly described and ascertained in and by the 5
following statement :—

Figure 4 is a plan of a lever E+ hereafter referred to.
Heretofore when commencing to make knitted fabrics on knitting machines, To
set on, the attendant has taken a length of yarn and formed a series of coils with
it over the whole breadth of needles in each division, each coil enclosing two or
more needles, This I effect on each separate breadth of needles, or set of trans-
ferring points of equal breadth, the whole width of the machine to which the
apparatus may be applied, simultaneously by apparatus consisting of the following
parts.
The apparatus is shown as adapted to be applied to what is known as the cotton
type of knitting machine. To the right end standard or to the framing outside it,
I attach a bearing A and to each division of the machine a bearing A¹. These
bearings support a bar B which rocks and slides in them, this bar is provided with
as many thread guides C as there are widths of needles in the machine or widths
of transferring points to which the apparatus may be applied, at one end of the bar
there are a number of projecting studs D each the width of two or more needles
apart, the whole number being equal to the width of one set of needles or
transferring points, To facilitate the construction and erection of the apparatus,
the bar B may be in two lengths, connected by a coupling collar B₁ and set screws
as shown at Figure 1. The outermost studs D at the commencement of the set on,
clip the rim of the cam E which is slotted at one part and bent to the shape shown
at Figure 1 so as to allow one of the studs to pass through it at each revolution,
causing the bar B and the whole of the thread guides C to be traversed the width
of two needles or points to the right under them, the traverse being continued the
width of three more needles or points by a cam El secured to the left side of the
cam E being pressed to the right by a Truck E which revolves on an axle secured
to the left side of the bearing A while held to the right a cam E (which is also
secured to the left side of the cam E) passes within a projection on the right side
of the upper end of an angular lever E' (shown in plan at Figure 4) which rocks
on a stud secured to the left side of the bearing A, the lower end of the lever E*
is forked and clips the studs D as they are traversed to and fro, while actuated by

page_text: the cam the lever holds the rod B in such a position that the whole of the thread
guides C are above the needles or points, and while in such position they are
traversed back three needles or points to the left by a cam E' secured to the right
side of the cam E being pressed upon by a Truck F¹ which revolves on an axle
secured on the right end of a fixed axle F projecting from the upper end of the
bearing A. Immediately the cam E clears the lever, a spring E rocks the lever
so as to throw the thread guides below the needles or points as shown at Figures 1
and 3. A repetition of such movements results in each thread guide placing its
thread under five needles or points then up through them and back over three
needles, or points then down through them and again under five needles or points
such movements being repeated until a set on is made on each width of needles in
the machine or on each width of transferring points to which the apparatus may
be applied. The cams E E' E³ E³ are revolved in the direction indicated by the
arrows either by a belt passed round a grooved pulley secured to the right side of
the cam E and round a pulley on a counter shaft conveniently placed so that the
attendant is enabled to start or stop the apparatus at will, or the cams may be
revolved by the handle shown to the right of Figure 1.
At Figures 1 and 3 transferring points are shown in the same relative position
as the needles in a cotton type of knitting machine when commencing to make a
knitted fabric.
The Drawings show the Cams E E¹ E³ Es as set out to produce a set on upon
needles or points of eighteen guage, but the apparatus is equally applicable to
produce a set on upon other guages by simply changing the cams for others set out
to the required guage coarser or finer and taking away the studded right end
length of the bar B and substantiating a length having studs of a guage to
correspond.
By means of the Improved apparatus above described I am enabled to produce a
perfect regular set on, at the commencement of making either hose, half hose,
shirts, pants, or other knitted article at a considerable greater speed than can be
effected by hand.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
The construction and employment of apparatus to produce a perfect regular set
on substantially as described and illustrated in the Drawings annexed.
