1 Claim.
This invention relates to a method and means
for laying-in elastic strand in the edge of a mesh
fabric.
In the weaving or knitting of mesh fabrics
such as adapted for use in the manufacture of
trating the means for shuttling the elastic strand.
Figure 3 is a similar view with the parts in
another position.
Figure 4 is a view of a hair net formed accord

an elastic strand in the edge of said fabric so
the initial portion of this speci?cation will deal *
that when the net is‘ made up the selvage edge
thereof'is provided with the property of intimate
Q 1y hugging the face and neck of the wearer.
‘This type of hair net is well known but hereto

Oi had to have ‘a uniform repeat mesh since that
type of knitting is characteristic of these ma
chines. The laying-in of the elastic strand is
a natural function of machines of this type and

with those portions of a Jacquard Raschel knit
ting machine which are old but pertinent in car
rying out the purposes of the invention. On a
frame 5 there is carried a sinker bar 6 having
a plurality of sinkers 1 arranged in banks as
shown.
In association with the sinkers are arranged
the knitting needles 8, in the present instance, 15
of the bearded type. These needles, carried by
the needle bar 9, are moved up and down in a
reciprocatory manner to accomplish the knit
ting of the yarn Hi into the mesh N. This move
ment is relative to the sinkers, and the needles

In order to lay-in an elastic strand in the
signs. This is incapable of accomplishmentron
the knitting, machines above mentioned and
hence resort was had to the Jacquard Raschel
knitting machine.
This type of knitting machine, as commonly
used, does not lend itself to laying-1n an elastic
‘ strand in the edge of thefabric produced, hence
the invention seeks to provide means for laying
in elastic strand in the selvage edge of a knitted
fabric and'thus provides a new method for ac
complishing the purposes of the invention.
In the present instance, since the needles in
Jacquard Raschel machines have only a recipro
catory movement, it is necessary to provide means
for, in e?ect, shuttling the elastic strand from
:0 one side to the other of the end needle of a bank
of needles, and it is this means which forms the
basis of this invention.
,
In the accompanying drawing in which the
invention is illustrated in semi-diagrammatic
:5’ form, a preferred manner of practicing the in
vention is shown. This drawing together with
the following speci?cation comprises a complete
disclosure of the invention as at present con
templated.

In the drawing:—
Figure 1 is a semi-diagrammatic broken cross
sectional view of the knitting members of a Jac
quard Raschel knitting machine and including

features of the invention.

selvage of a mesh fabric as produced in the ma
chine, it is necessary to provide means for mov
ing the elastic strand from one side to the other
of the needle associated with the outermost sink
er, since this needle does not have any endwise
movement in relation to its sinker. This is ac 30
complished in the following manner. An elastic
strand guide bar i3 is mounted for endwise move
ment in the machine frame 5 and a spring I4 is‘
employed to maintain this bar in one endwise
position. A cam l5, driven by any feasible por- 3
tion of the machine, is arranged to engage a. roll
er IE on the bar to move it to the other end
~ wise position.
Upon the bar l3, are carried a plurality of
tubes or. elastic strand guides l1 thru which pass
the elastic strands I8 which are preferably main;
tained in tension.
The character of the cam I5 is such as to cause
the bar I3 and thus the tubes H, to move in
one direction for one cycle of movement of the
needles, i. e., up and down once. As an example,
0
the needles move up and then down to form a.
stitch with the parts as in Figure 2. The cam
I5 then acts to move the bar l3 towards the
right.
With the parts in this position (Figure
3) the needles again move up and down to form
another stitch.
It is apparent from the above that the elastic
in one instance will be outside the'needle, i. e_.
remote from the sinker, and in the second in 65

While the invention is quite simple, it does seek
around the elastic strand to accomplish the to provide more commercially desirable articles
purposes or‘ the invention, and while the inven
of the nature herein set forth at a cast com-i
tion is shewn as being carried out in a simple mensurate with articles formed on the piain Rats-l‘
manner, it is, nevertheless, conceivable that im
material variations in design may be resorted
10 to by skilled persons in following the principles
here set forth.

With reference to Figure 4 in which the re
sult accomplished by the invention is illustrated,
the length of fabric from which the cap is
16 formed, may be knitted with a central area 20
of one form of design, the end areas 2| of an
other form of design, and intermediate areas 22
of a‘third form of design. This illustration is
indicative of the variegated designs which may be
employed and which were not capable of produc
tion on the plain Raschei machines. The mesh
fabric thus produced may now be formed into
the shape of a cap as shown, but in this instance

Having thus described my invention, what I‘
claim as new and desire to secure by Letters 1
Patent, is:
In a Jacquard Raschel knitting machine, a
bank of needles and associated sinkers, and means
for directing a length of elasticstrand ?rst to
one side and then to the other of the end nee- 1
dle of said bank whereby a tubular selvage edge.
is formed on the fabric knittedby said needles
and‘ sinkers and said elastic is positioned within
said selvage, said means comprising a guide for
the elastic strand positioned below the sinkers, 2
a bar carrying the strand guide and a rotary
cam for actuating said bar.
