This invention relates to a method of manu
facturing a knitted fabric,
Particularly, it is an object of my invention to
arrange the links of a pattern chain in such a
manner so that the machine will automatically
knit a diamond-shaped pattern.
More particularly, I have provided an arrange

such a position that the needles 58 in the bank
slide up and down, but leave sufficient space to
permit the fabric to cast oil. The needle bar 5|
is raised and lowered in the usual manner by the
needle cams 54-—54 which may either be single
or double action cams. Cam-s 54 act through cam
arms 55 which are pivoted at 55 and restricted
lifter rods 5'! on which the needle bar 5| is
mounted, the needle cams '54 are on the main
ment of links for the pattern chain which oper

I have illustrated a machine showing two guide

bars, one guide bar ‘being numbered 59, and the

only two guide bars, since the machine can read

in Figs. 3 and 4, it should be understood that the
same movements which are created by the pat

cated by the use of cut wheels, the edges of which
are cut at varying distances from the center to
create the different heights. This is an equiv is
alent for the links of the chains illustrated in
Figs. 3 and 4 which are also of varying height.
In Figs. 3 and 4, I have illustrated the two pat

The fabric heretofore described and the rela
tive heights of the links to create this fabric can
be made by reversing the direction of the threads,
that is, threads that loop around the needles
from right to left can be looped around the needles
from left to right so that in the ?nal appearance

method will look exactly the same.
