This invention relates to mechanism for and
method of effecting changes in plating.

may be readily understood, we have in the ac

reverse plating is effected in lines, bands, blocks,
dots or other areas which are of precisely the in- '

and method of our invention, we are able, to make

we employ a ' special instrumentality for each

as to insure the continuation of normal plating

the sinkers 5 and jacks 6 during normal plating,

butt 8 never comes in normal plating in contact
of the loops back down to the normal lower knit

the sloping edge 29 were not provided but had
been level or ?at instead of wedge shaped.
In normal plating the loops remain below or in 40

Figs. 3, 4 and 5, and also from Fig. 9; but in re

the top of the nib 32 and down the back edge
of the same and the back edge of the sinker, as 45

shoulder 24 of that jack contacts with the end

said sinker a slight inward movement that would
not be imparted by the outer guiding edge of the

reverse plating may be of a single needle width or

to normal .plating for the very next needle wale.
Of course, the reverse plating areas may be of any

Having thus described certain illustrative em
bodiments of the invention, it is to be understood
that although specific terms are employed, they
are used in a generic and descriptive sense, and
not for purposes of limitation, the scope of the
invention being set forth in the following claims.
We claim:
1. In ‘a knittingmachine of the independent
needles type, a series of needles, means for feed
ing two yarns thereto in a plating relation, a sinker
like special instrumentality for each needlemov
able transversely of the needle series, and having
an edge formation cooperating in e?ecting re
verse plating, a,jack located in the same groove
as and beneath each instrumentality, and means
to move said jacks-thereby to move the desired
instrumentalities to cause the edge formations "
thereof to co-act in effecting reverse‘ plating, in
combination with means for controlling the
needles and special instmmentalities to effect the
knitting of normal plating.
‘
2. In a hitting machine of the independent. 70
needle type, a series of needles, means for feed

sinker like special instrumentality for each needle
movable transversely of the needle series, said in
.strumentalities and needles actini; to bind the
4
2,126,198
threads so that reverse plating occurs only at the
actual needle or needles whose instrumentalities
are moved transversely a distance in'excess of
the normal movement required for normal plat
ing, each of said lnstrumentalities having at its
forward part a binding edge for the threads and
having a top nib, over the top and down back
of which at least one of the threads passes in
reverse plating, and a jack for each such instru
10 mentality, and means to move said lacks so as
thereby to move desired lnstrumentalities in ei
fecting reverse plating.
3. A method of knitting plated areas including
feeding two yarns to the needles of a knitting ma
15 chine in a plating relation and effecting the knit
ting of stitches, causing lnstrumentalities 00operating with the needles to ‘eifect a reversal of
the yarns at one or more of the wales knitted by
the said needles, and causing an adjacent instru
mentality next in advance of a needle whereat‘
reversal of the yarns is not to occur, to act upon
the yarns by engaging them before reversal of
other instrumentality acts upon the yams to pre
vent reverse plating e?ected by the last men
tioned instrumentality from causing reverse plat
iing to be eifected at the wale knitted by a needle I
located between the said last mentioned instru
mentality and the instrumentality in advance
thereof.
-
5. A knitting machine having independent
needles and cooperating lnstrumentalities for ef
fecting the knitting of plated stitches, the instru 10
mentalities being constructed to effect normal
plating at some wales and reverse plating at other
wales, the construction and operation of the said
lnstrumentalities being such that reverse plating
is e?ected at a wale where the plating relations 15
of the threads are governed by one of the said
lnstrumentalities and, at a wale knitted immedi

thereby prevents the reverse plating e?ected by the
?rst mentioned instrumentality extending beyond
the yarns by the adjacent instrumentality in, the , the wale effected in the direction of the second
direction of yarn supply can effect reversal of mentioned instrumentality.
