19 Claims.
This invention relates to improvements in knit
ting machines.
The primary object of the invention is the pro
vision of improved means for automatically con
5 trolling and positioning the feed yarns of a knit
ting machine relative to the needles of the ma- _
chine, so that the operation of placing the wrap
yarns upon the needles may be efficiently carried

Figure 6 is a horizontal sectional view taken
substantially on the line 6--6 of Figure 1.
In the drawings, wherein for the purpose. of
illustration is shown only a preferred embodi
ment of the invention, the letter A may generally
designate the improved knitting machine, which
may be generally of the type set forth in any of
out Without much of the'manual labor and extra

A further object of the invention is the im
proved means for automatically lifting the yarn
feed head lassemblage of a knitting machine to
an out of the way position relative to the needles,
at the end of _the knitting of a stocking, or at
any other desired interval during the knitting op

The machine A may include a frame B; rotary
cylinder C; a set of needles D for the cylinder C;
a rotary bobbin head E; a vertically movable wrap
yarn feed head assemblage F, which includes a
1
movable frame G and the individual wrap yarn
feed fingers H. The machine also includes the
eration.
A further object of this invention is the -pro- means J for automatically lifting the head as
vision of improved means, connected with the semblage F to an out of the way relation relative
to the cylinder and needles of the machine at pre
20 yarn feed head assemblage of a knitting machine,
20
for automatically locating the yarns in position ‘ determined operations. Furthermore, the ma
for effective placement upon the needles of the chine includes the improved means K in the na
machine by the yarn feed fingers or members of ture of a plunger or extension of the head frame
the assemblage.
'
'
'
Other objects and advantages of this inven
25
tion will be apparent during the course of the fol
lowing detailed description.
In the accompanying drawings, forming a part
of this specification, and wherein similar refer-v
30 ence characters designate corresponding parts
throughout the several views,
Figure 1 is a fragmentary side elevation of the
improved machine showing the yarn feed head
assemblage in feeding relation to the needles of
35 the machine.
Figure 2 is a view similar to Figure 1, but with
the yarn feed head assemblage elevated to an out
of the way relation with respect to the hook ends
of the needles of the machine, so as to permit the
40 operator to have access to the fabric and needles
of the cylinder, etc.
Figure 3 is a fragmentary vertical sectional
view_taken through the cylinder of the knitting
machine and the adjacent associated features of
45 the yarn feed head assemblage; showing the im
proved means associated with said assemblage for
positioning and controlling the wrap or other
yarns relative to the feed lingers and needles of
the machine.

G and attached .to the latter for controlling the
position of the yarns relative to the hook ends of
the needles D and the yarn feed ñngers H, as will
be subsequently described.
The _details of the machine A, as above men
tioned, are generally shown in my three above
identified co-pending'applications. The machine
is of the rotary cylinder type, and of course it
includes the usual swinging latch ring L, which is
pivoted at 20 (see Figure 3 of the drawings).
This latch ring L has the usual body yarn and
other feed fingers associated therewith (not
shown) and the said latch ring may further in
clude the yarn restraining members 2 I, shown in
Figure 3 which cooperate with the wrap yarn feed
fingers H in restraining the yarn for feed upon
the desired number of elevated needles, all of
which is more specifically disclosed in my above
5
identified co-pending applications.
The frame B of the machine ‘is provided with
means for rotatably supporting the bobbin stand
E, and this bobbin stand E is driven through
means 23, shown in Figure 1, and well understood
in the art. The bobbin stand E preferably does
not elevate or lower, but remains at one level,
notwithstanding the fact that it is rotatable. On
the other hand the yarn feed- head assemblage F 50
elevates and lowers relative to the bobbin stand,
and relative to the cylinder C and'the hook ends
of the needles, in order that the feed fingers H
may be placed into or out of feeding relation with
the hook ends of the needles. Thus, the head as

more specifically disclosed in my above identified
_no-pending applications; these feed fingers H
having apertured lower ends 38 for threading of
the yarns therethrough. At their upper ends the
15 feed ñngers H are provided with suitable- butts
35, at different levels for operation by any of a
group of cams 36, also placed at different levels.
These cams 36, as shown inthe drawings, are
actuated by means 31 more specifically disclosed
20 in my above identified co-pending applications.

'I’he bobbin stand E of coursel supports any
25 desired number of bobbins 48; the yarns of which
are extended from the bobbins upwardly through
suitable tensioners 4| and then thru spring take
up devices 42, shown best in Figure 2 of the
drawings; the yarn being from this point
30 threaded downwardly through the head frame G
and through the apertured ends 38 of the yarn
feed fingers. ' Due to relative movement between
the feed fingers and the bobbin stand as >when
the former is- elevated and lowered, the take
35 up devices 42 keep the yarns 58 taut.
The means K for controlling the position of
the wrap yarns 58 relative to _the needles prefer
end of certain‘knitting operations in' order to
prevent the `weight from slappingthe stocking
against some solid vportion of the frame of the
machine. The improved means K is entirely
automatic in operation, and entails no move upon 15
the part of the operator except to knot together
the ends of the yarns below the head end 63.
Lowering of the head F will place the yarns in
position for feeding to the needles upon move- l
ment of the respective yarn feed fingers. The
take-up'springs 42 pull the yarns 58 taut beneath
the head 63.

It is of course to be understood that Ido not "
wish the invention limited to use upon a wrap
yarn head type of knitting machine. 'I'he con 25
trolling member K may generally be used in con
nection with g any yarn feeding apparatus for
automatically or effectively controlling and plac
ing the yarn in such -relation that‘it will be fed
to the needles of the machine at a desired move '30
ment` of either a needle or yarn feed member.
It could be used externally of the cylinder for
that type of feed member which moves from the
outside of the ‘cylinder to the inside of the cylin

It is to be noted that when the head F is low
ered the member K holds the yarn in deñnite
relation at a point below the hook' ends of the
needles, so that when the feed fingers H are
65 swung outwardly above the needles the yarns
mg rod s3 with the end of the yoke 1ever s2
opposite the yoke end. With this leverage
mechanism a small cam throw of the drum 38“
will transmit a relatively long leverage move
ment to the yoke end of the lever 82, and thus
raise and lower the yarn feed assemblage F be
tween the position shown in Figures 1, 2 and 3 65
of the drawings.

It is customary practice on conventional ma
chines embodying a wrapping head to tie all of
the wrap yarns together in a knot prior to low

a spring operated detent |88 which engages the
yoke lever 82 and holds the head F elevated, as 70
shown in Figure 2 of the drawings. A handle

much labor and time will be saved in the opera

machines, where the stocking is taken 0E of the
machine at the end of knitting of the toe; it is
usually necessary for the operator to manually
lift the heavy wrap yarn head and to re-arrange

top has been placed upon the needles) it is
merely necessary for the operator to knot the
ends of the wrap yarns togetherv below the im

lowering of the wrap head the Wrapyarns will
be in position for accurate feed upon the needles
of the machine when the respective wrap yarn

invention herein shown and described, without
