Year: 1884

page_text: TROYISIONAL SPECIFICATION,
We, BENJAMIN KERR, of 82 Havelock Street, Machinist,, and EDWIN NEWTON
80 Jarron Street, both of Leicester in the County of Leicester, Overlooker, do
bereby declare the nature of our invention for "IMPROVEMENTS IN CIRCULAR
HOSIERY MACHINES to be as follows:-
.
"
'
Our improvements relate to circular knitting machines such as the Griswold and
Hainworth, the Automatic, Starr and similar machines, by which we are enabled
to produce fashioned, plain, tubular, knitted fabrics. Instead of a dial carrying the
machine needles we employ a dial of smaller diameter having radiating slots of
equal guage and number to the frame needles in each slot instead of the machine
needles, we place a point each of which is projected between the frame needles by,
a cam, while they are drawing their loops instead of drawing their loops on the
leaves of the frame cylinder, and when the fabric is required to be narrowed we
withdraw two frame needles, and take out a point on each side of the groove, from
which a frame needle was withdrawn and transfer the loop. from each frame needle
onto the next adjacent needle right and left outwards or inwards so that as the
needles take the thread to form their loops, such thread not being drawn down
between the points, stretches from one needle to the other, thereby forming fabric
of the same guage and stiffness, round the whole circle. Or instead of the points
and dial before named we employ vertical sliding leaves in the frame cylinder,
between the frame needles in a portion of the circle, or we cut off the tops of the
leaves for a portion of the circle and for each portion so cut off, substitute a loose
top to each leaf, each loose top, lying in a slot in the top of the cylinder, is held in
position by a spring secured on the front of the cylinder. When the fabric is
required to be narrowed, we withdraw two frame needles and transfer their loops
to the next adjacent needles and either lower or remove the top of a leaf next, the
groove, from which a frame needle has been withdrawn so that as the needles take
the thread to form their loops, such thread not being drawn down between the
leaves, stretches from one needle to the next adjacent needle, thereby forming the
fabric of the same guage and stiffness round the whole 'circle.

We, BENJAMIN KERR, of 82 Havelock Street, Machinist, and EDWIN NEWTON
of 80 Jarron, both of Leicester, in the County of Leicester, Overlooker, do hereby
declare the nature of our invention for "IMPROVEMENTS IN CIRCULAR KNITTING
MACHINES," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-

cylinder, and the dial. we employ.

plate hereafter referred to.
Figures 5 show side views of. certain sliding points we employ.

Like letters indicate corresponding parts throughout the Drawings.
Our improvements relate to circular knitting machines such as the Griswold and
Hainworth, the Automatic, Starr and similar machines, by which we are enabled
to produce fashioned plain tubular knitted fabrics.
Instead of a dial carrying the machine needles we employ a dial A of smaller
diameter than the ring of needles in the cylinder B, the dial has radiating slots
shown in plan at Figure 3 of equal guage and number to the frame needles in the
vertical slots in the cylinder B:
In the Drawing the dial A and cylinder B are each shown as having one half
cut to an eighteen guage, and the other half cut to a twenty four guage, the slots
in the finer guage of the dial are cut somewhat shallower than the slots in the
coarser guage, but we do not confine ourselves to such guages, as they will vary
according to the guage of fabric required to be made.
In each radiating slot of half the dial we place a point C, where it is cut to the
eighteen guage, and in each slot of the other half of the dial cut to the twenty four
guage we place a point C¹, side views of these points are shown at Figures 5.
Each point is projected between the frame needles by a cam D while they are
drawing their loops, the loops being drawn upon the points instead of on the leaves
of the frame needle cylinder B in the usual way. The dial A is secured to the
lower end of a vertical axle A' and is caused to revolve with it, by the post usually
employed to drive the machine dial, the cam being held in the position it is placed
by the attendant by the pin previously employed to hold the machine dial, the
vertical axle A¹ passes through the cam D and its cover plate D³, an underside
view of the several parts forming the cam is shown at Figure 4 and in plan by
dotted lines at Figure 1, the cam D which is secured to the cover plate is slotted to
allow of the to and fro movement, of an outthrow incline plate D¹, which when
adjusted is held in position by a thumb screw D*, passed through a slot in the

page_text: cover plate, the incline plate regulates the projection of the points C and C¹, the
points are prevented from sliding out of the dial by 'a plate D' which partly
surrounds the cam D, the space between the two receives the vertical bends of the
points, the points are also prevented from being projected too far by an adjustable
cam plate E which is pivotted at one end to the cover plate and is capable of
adjustment at the opposite end by a screw E¹ passed through a slot in the cover
plate.
To prevent the points being thrown out of the dial by suddenly reversing its
revolution we employ a cam plate D³, secured by a screw to the top of the cover
plate and projecting downwards so as to nearly touch the stem of the points. To
obviate the necessity of taking out a point where a narrowing is required to be
made, we hinge the outer ends of the points C¹ to the main stems as shown at
Figures 5, and turn the outer end up and back as shown at C when we do not
require a loop to be draw upon the point. Portion of the cam ring outside the
frame needles we make somewhat shallower than usual so as to allow the needles
to fall lower to enable an easier transfer of the loops when narrowing. An inside
view of portion of the cam ring F upthrow cans F and stitch cam G is shown laid
out flat at Figure 6.
The remainder of the machine is of the usual construction.
When the fabric is required to be narrowed we withdraw two frame needles, and
either take out a point Ĉ or else turn up and back the front end of a point C¹ on
each side of the groove from which a frame needle was withdrawn and transfer
the loop from each frame needle onto the next adjacent needle right and left
outwards or inwards so that as the needles take the thread to form their loops,
such thread not being drawn down between the points stretches from one needle to
the other, thereby forming fabric of the same guage and stiffness round the whole
circle of fabric.
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
In a circular knitting machine
First. The construction and employment of a dial to carry points to draw loops
upon.
Second. For the double guaged dial and cylinder of equal numbers to produce
an equal guage of fabric all round.
Third. The cam D, incline plate D¹, cover plate D³, cam plates D*, D³ and
adjusting screws D³ and E¹ for operating the points in the dial substantially as and
for the purpose set forth.
Fourth. The points C and C to draw loops upon, instead of drawing the loops
on the leaves of the frame needle cylinder.
