Patented Jan. 12, 1932v UNITED STATES PATENT OFFICE THEODOR VORCK AND PAUL ZIMMERKANN, OF BARMEN, GERMANY, ASSIGNORS T0 MESSRS. J'OHS. GIRMES & CO. AKTIENGESELLSCHAFT, OF OEDT NEAR KREFELD,
GERMANY WARP-KNITTING MACHINE Application filed July 19, 1927, Serial No 206,833, and in Germany December 12, 1926 -be used when required, without structural alteration, in the usual way, that is for the manufacture of known kinds of fabrics.
In order that the invention may be clearly understood and readily carried into practice, we have appended hereto two sheets of drawings, in which Fig. 1 is a sectional end view of a portion of a. machine embodying the invention; and
Fig. 2 is a fragmentary side view of the weft guide members and the means for operating them.
The guides a for the knitted warp threads K, K, K K are carried by bars suspended in the usual way from a swinging beam 6. In a space formed by the omission of one of the usual thread guide bars, is arranged a bar 0 provided with weft guide fingers e, e mounted on supports having tongues or ribs sliding in longitudinal grooves of channels (I, (1. These fingers, which guide the wefts 8, 8 are positioned according to the breadth of a the fabric, and are actuated by the driving pins or tappets f, f.
The driving pins or tappets f, f are fastened to bars 9, g, which may be, similarly to the thread guide bars, movable laterally, but are also pivotally mounted so that either or both of the tappets can be put out of action at will. By displacement of the bars 9, g, the tappets f, f can be swung into.
either of the. positions shown in full lines and dotted lines respectively, so that they will strike either of the thread guides e, e.
In the position of the parts shown in the drawings, crossed-double wefts S, S, S are being inserted, i. e. wefts are being inserted simultaneously from both sides of the fabric. If the driving pins or tappets f, f are moved into the positions shown in dotted lines, they run without working, that is to say, neither of the two weft guide fingers is actuated, and no weft is inserted. If only the upper or the lower driving pin or tappet f is moved around out of the position shown in the drawings, then one only of the two wefts is inserted.
The driving pins f, f may, of course, be shaped differently, and the bars 9, y can be operated by any suitable means other than a cam drum.
In the case of a single instead of a double weft arrangement, a single weft thread guide finger may simply be secured to a bar, which is suspended similar to the thread guide bars, from a bar on which it can freely slide longitudinally.
The number of the thread guide bars may, of course, be varied. For the most usual fabrics the thread guide bars 1, 2 are not utilized, that is to say, they carry no warp threads.
The weft thread arrangement may be provided between others of, the thread guide bars instead of between the ones shown: it is also possible to provide several such devices in different positions at the same time. Moreover, a known kind of weft arrangement h, preferably a double one, may also be provided in front of the needle rail, for laying an ordinary weft thread 8.
If two weft arrangements according to the invention are provided, or if one such arrangement, and another weft arrangement in front of the needle rail are provided, the advantages are obtained that with only on! latch needle rail, front and back wefts can be inserted at the same time. That is to say, one weft is inserted by means of the deviceJz in front of the warp K, and the other weft is' inserted by means of device 6, e behind the warp K, so that the two weft threads of the whole width of the fabric.
It should be understood that the above described construction'is not essential to the invention. It should further be understood that in a fabric having several wefts, the various wefts may be laid either simultaneously or alternately by suitable arrangement of the operating cams and other mechanism.
What we claim is 1; A warp knitting machine, comprising in combination, a latch needle bar, a plurality of warp thread guides disposed in parallel relation, means operative intermediate the formation of successive stitches for laying wefts between the warp threads carried by said guides, and means also operative intermediate the formation of successive'stitch'es for laying other wefts on the. outer side of said warp threads.
2. A warp knitting machine, comprising in weft guide fingers secured to said supporting members, and tappets mounted ad acent to said bar for reciprocation longitudinally of the bar and adapted to engage said supporting members thereby to move said weft guide fingers. I 5. A warp knitting machine, comprising in combination, a needle bar, a series of parallel movable bars carrying cooperating warp thread guides, another parallel movable bar disposed between a pair of saidfirst bars and provided in opposite sides thereof with longitudinally extending guide channels, supporting members having ribs seated in said channel for movement longitudinally therein, weft guide fingers secured to said supporting members, and tappets mounted adjacent to said bar for reciprocation longitudinally of the bar and adapted to engage said supporting members thereby to move said weft guide fingers, said tappets being angularly adjustable into and out of engaging position thereby to selectively operate said weft guide fingers.
In testimony whereof we have signed our names to this specification.
THEODOR VORCK. PAUL ZIMMERMANN.
