Improvements in Knitting Machines for Producing Longitudinally
Striped Goods.
We SAMUEL WULLSCHLEGER, Manufacturer of Knitted Goods and KONRAD
RURY, Physician both of 8 Rebgasse, Basel in the Republic of Switzerland do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide straight or circular knitting machines
with mechanism by means of which such machines are rendered capable of knitting
fabric with longitudinal stripes of different coloured yarn, said stripes being
continuous or broken at regular or irregular intervals as desired.
J
To this end, in front of the needles are journalled a number of rollers at suitable
distances apart according to the distances separating the stripes in the fabric to be
knitted. Near each roller is a spool of the yarn for knitting the respective stripe,
the end of yarn passing first through a wire loop, thence to the roller, where it is
massed through a hole or eye thereon. By revolving each roller for a half turn the
arn is brought in front of the respective needle or needles and knitted into the
fabric. To turn the rollers a sliding piece is provided with a leather or other
tongue so placed that when the said sliding piece is raised by the action of a spring
or by suitable gear from the main shaft, this tongue strikes against the edge of each
roller and revolves the latter in passing. The sliding piece moving in suitable
guides may be pressed down by hand and locked by a suitable detent in which case
the knitting of stripes is interrupted or in a machine provided with pattern gear
the sliding piece will be automatically placed into and out of engagement.
To form the loop it is necessary to turn the rollers back again cach time into
their first position and this is effected also by a sliding tongue mounted for
convenience on the main yarn feed or guide and movable to operate in contrary
direction on the rollers.

page_text: The object of the invention is to enable knitted goods having stripes running in
the direction of length of the fabric to be made upon circular knitting machines.
LL is the frame carrying the vertical or frame needle cylinder Z. N is the frame
cam cylinder which revolves around the needle cylinder Ź and is driven by bevelled
gear K from the shaft, M in the known manner. The ribbing needle disc Dis
supported in the known manner upon the shaft D¹ of the ribbing cam disc P which
is carried by the arm D² on the pillar D³. The frame C attached to the cam
cylinder N carries the main thread bobbin S the thread of which is carried to the
thread guide Q upon the bracket R on the frame C.
C
To provide for the insertion of threads to form the stripes upon the fabric W
at suitable places along the ring A which retains the frame needles and is fixed on
the needle cylinder above the cam cylinder N, are placed pins for carrying the
small reels or bobbins for the respective threads; on the ring A. are also pillars c
carrying the rollers e each adapted to revolve upon the pillar el supporting it and
arranged with its axis horizontal and in a radial line from the vertical axis.XX
of the machine each roller carries the eccentrically placed projecting tube » through
which the respective threads is passed from the bobbin b. The roller c has the
flange or flanges e² for a purpose hereinafter shown. The ribbing cams are
revolved with the frame cams by the arms B connected to the sleeve J on the
shaft D' and brought into connection with the frame cam cylinder N in the usual
manner. The pin P connects the cam disc P to revolve with the arms B when
the latter are driven with the frame cam cylinder N. On one of the arms B is
the sliding bare connected thereto by pins and slots e². On one of the pins e¹
is pivoted the latch d having the turned over end adapted to take into a recess w
in the sliding bar e and lock the same in its lowest position when desired. The
tail of the latch d is connected to the tail of the plate e by the spring p so that
the same spring. lifts the latch by drawing down its tail and lifts the sliding, bare
into its highest position when not retained by the latch d.
In this highest position of the sliding bar e the projection thereon which may
be of leather, stands in a position where, during the revolving of the arm B this
projection touches the lowest lying part of the Hange or flanges c² of each. wheel c
so that the wheel is revolved for an appreciable distance.
On the frame C is a similar sliding bar y attached by pins and slots and having.
the projection of the same nature as the projection but intended to act upon the
upper lying part of the flange or flanges c² of each wheel c and thus act to revolve
each wheel in a direction contrary to the motion imparted by the projection f
The action of either one of these projections as desired will revolve the wheels e so
as to bring the threads projecting from the tube thereon into engagement with
the latch of the ribbing needle which stands opposite the tube r. By this means
the respective ribbing needle which will have been pushed forward to receive the
thread by means of the cams will receive both the main thread in the usual way
and the stripe threads, the latter however lying in front of the former so as to
show upon the outside of the finished fabric. The other projection will operate to
return the roller to its first position while the needle draws the loop and throws off
the standing-loop.in the usual manner. The next rotation will again loop the
respective threads in the same manner over the same needle so that the second loop.
is formed in like manner. By successive rotations of the machine stripes are
produced longitudinally with the fabric at or upon those ribbing, needles which are
respectively opposite the rollers c. By suitable arrangement or grouping of the
rollers e various patterns of stripe may be produced.
By moving the position of the rollerse during the work by suitable shifting to the
right or left with movements according to any suitable pattern it is obvious that in
place of making longitudinal stripes, any desired diagonal, spiral zigzag or inter-
mittent pattern may be produced if the movements of the rollers c are such as
to bring them opposite the respective needle on which the fancy stitch is to
be made.
Interrupted stripes may be produced by setting the stripe mechanism out of

page_text: action during the desired number of rounds by moving one or both projections
out of action.
The bar g is held out of action when desired by lifting the same and securing it
in its upper position to screw down the screws on which it is guided.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
In a knitting machine for the manufacture of knitted goods having longitudinal
or diagonal stripes or the like
1. The combination of a maint hread guide, a series of stationary auxiliary thread
guides located respectively with regard to the needles on which the stripe or
pattern stitches are respectively to be knitted, a projection adapted to rock said
auxiliary thread guides whereby their threads become engaged with the said
needles and a second projection adapted to return said auxiliary thread guides to
their original position and means for supporting the auxiliary thread guides and for
supporting and actuating the main thread guides and the two projections aforesaid
substantially as set forth.
2. A. series of thread guides consisting each of a wheel c having a flange or
flanges and an eccentrically placed thread guide tube in combination with a
projection adapted to rock said wheels in one direction and a second projection
adapted to return the said wheels to their first position and means for supporting
said wheels c and for supporting and actuating the said two projections substantially
as and for the purpose set forth.
3. In a circular knitting machine a ring A having thread spools and thread
guides thereon located respectively with regard to the needles on which the
stripe or pattern stitches are to be knitted in combination with the cam cylinder
provided with the bars e and g having projections and hand rotating with the
cams substantially as and for the purpose set forth.
