PATENT OFFICE.

The purpose of the present invention is to provide greater versatility in manufacture from prefabricated patterns on French circular looms of old and new systems grant than is possible with the previous means.

With the type of pattern that is now in use, in which first loops on all needles are cultivated, and then only those needles on which the pattern stitches are to appear, be squeezed, one is in the removal of these individual priced needles very limited from one another, since it succeeds at most, with an overlap of five to six Needles that are not priced to form pattern stitches. If you go in number of the needles lying next to one another, the next to one another stretch first trimmed stitches are very elongated, in that they take up part of the culverted thread of the unchecked stitches; furthermore, so much of the loose thread that has not been tied into mesh remains on these unpriced needles lie that the same is entirely true in the case of hard yarns such as worsted and mohair pops out of the needles and then again from the sinkers of the next mailleuse is grasped, whereby either unclean goods or by cutting the thread holes develop.

All these evils can be avoided, if, first of all, with the needles, on them no pattern stitches are to be formed, no thread is cultivated, and secondly these Needles are barked before the sinkers take the thread lying stretched on the needles pull under the tips of the needles; so that the thread comes to the tips of these needles and is pressed when pressing the adjacent pattern needles (i.e. the needles on which the Pattern thread is correctly cultured) at the same time cut off. The apparatus that achieves this goal is shown on the accompanying drawing.

In the support a, which is held by means of the round column b from the angle c attached to the disk of the machine, the Mailleusen axis d runs in points. On the inner end of this axis is the drive wheel e, which is provided with hyperbolic teeth and engages either in the drive ring of the latter on machines with a large Stuttgart mail lock or in the needle ring behind the knock-off plates on machines with a small French mail lock. The brass sinker plate f is firmly seated on the front end of the axle, in which the sinkers g can move radially, as in the Jacquin Mailleuse. Behind the sinker disk, the disk / 2 is rotatably seated on the axle and at its lower end contains a slide h _t that can be adjusted vertically in it. So that the disk h and the slide cannot participate in the rotation of the axis, the screw i, which passes through the support a , engages in the former.

Towards the disk h , the sinkers have small noses protruding from the sinker disk f , with which they grip into an annular groove in the former. At the point where the sinkers are supposed to hold the thread, this ring groove is broken and the adjustable one

Claims (1)

Slide H ₁ inserted; When turning the sinker disc, this forces the sinkers, which are moving with their nose under it, to quickly make a downward movement and to culminate the thread. As can be seen from the Grundrifs ι (Fig. 3), the axis of the Mailleuse I is offset to the needle direction, it lead the sinkers, while they go under the slide along, the loops culminated close to the inner needle tips up to the outer needle tips at which point the boards are lifted again by the slider. The latter is adjusted by means of the screw k, which is rotatably mounted in a clamp of the disk h and is moved up and down by the bracket / slide. If it is in a higher position, short stitches are formed, and if it is in a lower position, long stitches are formed. Right in front of the sinker disc is located, firmly screwed to the same, the pattern press wheel m, which therefore turns around quite evenly with the sinker disc. With its toothed edge, this press wheel presses the tips of the needles, on which no loops are to be cultivated, into their teeth, and this closing of the needle tips takes place before the sinkers can pull the thread under the tips (Fig. 4). At ! the needles on which stitches are to be formed, the teeth of this wheel are m cut, it can thus reach the kulirten grinding in the usual manner in the needle tips. Furthermore, since a stitch formation cannot take place at all on the needles that are closed by the Prefsrad m by removing the associated sinkers g from the sinker disk f , the thread is simply stretched smoothly over these needles on the closed tips and it becomes this straight piece of thread when knocking off the old stitches tying in the new pattern stitches is immediately pulled down completely from the needles, so it can never get under the sinkers of the following j mailleuse and cause errors here. Close to the left of the Mailleuse is the well-known tee with tee press η and ο , which integrates the knitted loops of the pattern thread into finished stitches by knocking off the related old stitches. As can be easily seen, the Abschlagprefsrad 0 must be divided opposite to the Prefsrad m , ie the needles that are not pressed on the Prefsrad m are priced on the Prefsrad 0 , and vice versa. In order to strongly support the needles during the killing of the thread and to prevent them from bending, a wheel divided according to the pattern, the support wheel p, engages under the needles just behind their outer tip, so that they are extremely beneficial during the killing of the thread being held. The teeth of the wheel p, which meet the needles pressed by the wheel m , are cut out so that these needles can bend freely downwards. With the help of this device it was possible to smooth the thread over 25 to 30 needles lead, with extreme limitation of the consumption of pattern thread, which is during processing expensive yarns, such as silk, are very important. Finally, it should be mentioned that if you want to lay the pattern thread on the reverse side of the fabric a little looser, so as not to impair the elasticity of the tricot, this can easily be achieved by inserting one or more sinkers, even with the needles, which pass through the wheel m are pressed. The loops formed here, which cannot get under the needle points, simply serve to increase the pattern thread lying on the back of the fabric. Pa τ ε ν τ - A ν s ρ R r c η: A French circular knitting loom, in which, for the production of price samples with sample threads lying smoothly on the back of the fabric, the thread processed by a jacq uin mailleuse is only cultivated on the needles on which the pattern stitches are to be formed and which at the same time by pressing the other needles by means of a sample price wheel (m) located in front of the sinker disc, the non-culverted piece of thread is placed directly on the needle tips, which makes it possible to strip this piece of thread completely from the needles when tying in the new pattern stitches. For this purpose ι sheet of drawings.
