PATENT OFFICE.-
ERICK EARTH, OF CHEMNITZ, GERMANY.
CIRCULAR-KNITTING MACHINE.
Application filed May 12, 1923. Serial No. 688,671.
To all whom it may concern:
Be it known that 1, ERIC BARTH, a citizen of the German Republic, residing at Chemnitz, Germany, have invented certain B Improvements in Circular-Knitting Ma-- 1 also employed which hold the respective needles in a osition to catch the thread and which are either advanced or retarded in order to make the pattern run diagonally on the fabric.
In either case the angle of adjustment of the patterning elements is limited so that a continuous spiral pattern can only be produced by carrying the thread loosely at the back of the fabrlc from one pattern stripe to another.
This involves a considerable waste of material, and the arrangement does not lend itself to the use of different colours for adjacent pattern stripes.
1 The object of the present invention is to ada t the circular knitting machine for producing continuous diagonal patterns with out any transfer of thread from one stripe to the other, and the invention consists 1nv arranging the guide for the pattern thread stationary, and adapting the needle cylin der for rotary adjustment, a periodic displacement of the c linder being brought about. by there is nothing to limit the displacement of 60 the cylinder, the pattern can be carriedon continuously. in a spiral fashion, ently coloured threads may be used for the individual stripes.
Fig. 1 of the accompanying drawings rep- 5 resents a vertical section of the device,
Fig. 2, a plan of the same, and I Fi 3, 'a diagrammatic view illustrating the ormation' of the pattern.
Figs. 4, 5 and 6, are diagrams showing the old system of patterning, and
. Fig. 7, a diagram showing the system according to the present invention.v The needle cylinder at is carried by a ring der. Fig. 3 shows the formation of means of-t e camring drive. As'
and differ-{ chines unless the pattern is run in zig-zag 0 which is rotatably guided-in the machine frame 6 and which is formed integrally with or connected to a ratchet wheel 71. having as many teeth as there are needles in the cylinder. The cam elements (Z are carried by a ring 6 which is driven in the usual manner by means of a bevel gear f. The cam ring revolves once for each-revolution of the gear f. Keyed to the shaft of the latter is a ring 9 on which there is a tappet h. A doublearmed lever Z carries at one end a pivoted pawl m-which engages the teeth of the ratchet wheel n. The other end of the lever l is held by a spring against a roller is which is carried by a plunger. The latter is held in a guide '5 and is arranged so as to be operated by the tappet h at each revolution of the cam ring for advancing the wheel a one or more teeth according to requirements, the needle cylinder being adjusted accordingly. A detent pawl 0 controlled by a spring p prevents retrograde movement of the elements.
The patterning thread is held by guides q (Fig. 3) whichare fitted in a head 1' in the usual manner. However, while the head r is ordinarily displaced for producing the diagonal pattern, in this case it is held stationary, as the desired effect is produced by the rotary displacement of the needle cylinthe pattern b a displacement .of the needles to the rig t by one needle s ace for each course. The displacement can e carried on regularly throughout the length of the fabric which will have the appearance shown. more clearly in Fig. 7. It will be noticed that there are no loose threads at the back of the fabric as in the examples given in Figs. 4 and 6, the loose thread being shown at t. This is unavoidable in the ordinary maas shown in Fig. 5;
I claim v '1.- In a circular knitting machine, the combination with a rotatable cam ring and with a driving gear for operating the same, of a stationary guide for supplying the patterning thread, a rotatable needle cylinder, and connections between the driving gear andv the c linder 'for rotating the same intermittent y so as to produce a diagonal patml tern, substantially as set forth.
2. In a circular knitting machine, the combination With a rotatable cam ring and with a driving gear for operating the same, of a stationary guide for supplying a pat- 5 terning thread, arotatable needle cylinder, a ratchet Wheel connected to said cylinder, at spring-pressed pawl cooperating with said pattern.
