CLASS 86: Weaving.

The present machine belongs to the type of bobbinnet machine which the warp threads are divided into several groups according to the pattern, which separately by a jacquard gear on the side of the machine (e.g. so-called "Dropper jacquards") can be moved.

As in ordinary weaving, the warp threads are to a certain extent in "shafts" which, according to the size of the pattern, are moved back and forth to the side; only The lateral stroke of the shafts is also variable according to the pattern and therefore influenced by a sample card, facilities such as those on the high-end machines are generally used.

While so far with the tips manufactured on Bobbinnet machines, the special, e.g. B. stronger or differently colored threads formed pattern figures only applied on a certain side ("applicirt") could be, the present invention aims to provide a fabric which Contains pattern figure the same on both sides, so made in a similar way as embroidered with satin stitch.

If these pattern threads are to lie flat on both sides, this is only possible if they with their containers (spool slide) from one side of the tissue being formed the other are brought 'and then move to the side according to the pattern, then move back to the first side of the fabric and s. f.

The pattern threads are therefore on special above the usual row of bobbins Bobbinet sledge housed, which also has its own drive rods through the chain threads be driven through. Only it is still necessary to also move these spool slides sideways to move. For this purpose the upper reel carriages can be moved in the same way placed on special combs, in turn by a side jacquard gear to be moved to and fro laterally according to the pattern, and indeed as many separately moved combs are necessary as different combs Pattern threads are present in a pattern.

However, this rearrangement makes special movement means for the upper combs, slides and connecting rods required, for which the following versions be used.

Fig. 5 shows on an enlarged scale Carriage with bobbin of the lower row and Fig. 6 Carriage with bobbin of the upper row in side and front view, while FIGS. 7 and 8 in side and front view of one of the Comb pieces or bars (arched track for the coil carriage).

Before describing the individual parts of the machine, it is advisable to consider the To explain the mode of operation with the aid of FIGS. 4 to 4D.

The lower working mechanisms (located under the line / to J in FIGS. 4 and 4α) are known from the commonly used bobbinet machines; the warp threads c ¹⁰ arrive either from a yarn or. Chain tree or separate from individual bobbins to the two iron rods (thread guide rods) c ¹¹ (Fig. 4c; in Fig. 4 to 4B only one is visible), through whose openings they pass, to then over the rod H ^{1 that supports them} Stuff tree to run. Above the rods c ¹¹ move in fixed combs c ^ls c ^13, the bobbin carriages c ⁷ with their bobbins (bobbins) c ⁸ , as FIG. 5 shows. The movement of the sledge. c ⁷ from one to the other comb c ¹³ through the warp threads c ¹⁰ is caused in a known manner by the drive rods cc , which with their bars c ²⁰ engage in the gaps c ^{21 in} such a way that the front rod c over the front Gap c ²¹ lifted, opposite to the carriage c ⁷ , which in the meantime has grasped the rear rod c at its rear gap c ²¹ and retracted it into the position shown in FIG. 4B. Then both rods c move towards each other, the rear one ^{pushes the slide c 7} to the other comb (Fig. 4A), but releases at the moment where the. front rod c in the front gap c ²¹ , grips the slide and then moves back with the same. With each movement of the machine, the rods b slide on rollers b ³ in their path b ^l corresponding to the crests c ¹³ towards the center (Fig. 4a) respectively. "to the sides (Fig. 4B) in order to receive the carriages c ¹ and to support them in the maximum position. While the carriages c ¹ with the bobbins c ^{s are passed} through by the chain threads c ¹⁰ from front to back and vice versa, the two thread guide rods c ¹¹ by a located at the end of the machine (not particularly indicated in the drawings) jacquard apparatus opposite to each other to a lateral movement (see arrows in Fig. 4 c) caused, so that when the carriages c ⁷ die Position of Fig. 4 β take on the rear comb c ¹³ , the movement of the two rods c ¹¹ to the right and left occurs, whereupon the bobbins c ⁷ with their bobbins c ⁸ and threads c ⁹ through the ^{warp threads c 10} on the front comb c ^{13 are} brought and, now returning after reaching their highest position ^{, cut through those warp threads c l} ?, which in the meantime took place again, the jacquard pattern corresponding movement of the bar n c ¹¹ to the left or have been set on the right.

The parts arranged above the line / to J have the following equipment:

Instead of the usual bars (comb blades), which were combined by casting with lead to form combs that are fixed on the comb rods, individually or individually movable bars C of the form are used here, as shown in FIGS. 7 and 8. Each one in a front and in a rear. Row seated bolt C is attached to each one of the rods D, Fig.4bis4B, lying flat on top of one another, in such a way that only one respectively. several specific latches with. one of the bars D is connected in the manner as shown in FIG. 7 illustrates. In addition, the bars D are inserted in grooves c ^{20 of} the comb rods, which, as can be seen from the drawing, consist of two parts ^{C 1} and C ² connected by screws and thus enclose the rod friction DD. This arrangement ensures that the individual bars C, which are not close to one another like the lower c ¹³ , but leave space between them, can be moved independently of one another by the various flat bars DD in the transverse direction of the machine when the latter operated by a second Jacquard gear. The sinkers of this jacquard gear are connected to one end of the various rods D , while the other end of the same is attached to springs in the usual way.

The upper bobbin carriages E, the shape of which can be seen in FIG. 6, slide in the grooves C ¹⁰ , FIG. 8, the bolt C; they are somewhat stronger than the lower carriages c ⁷ , since they work with stronger threads or with cords which are located on the bobbins or bobbins E ¹ , which are held in their position in a known manner by a spring E ^20. The sleds E are at their lower part E ²¹ with the exception of the foot? ²² screwed in so that they are held by the overarching groove C ¹⁰ and do not jump out of it

can. The back and forth movement of the sled !? from one comb C to the other cause the drive rods E ^% and E ^e *, which will still be described in more detail, which engage with their strips E ¹ and E ⁷ * in the gaps E ^{so of} the carriage E. The serving to receive the stitches needle bars F ² and F ² * carry, as in the conventional Bobbinet machines, poured their rows of needles in Bleie- F.

Since the needle bars must move down between the upper combs in order to also take up the ^{thread loops formed by the lower bobbin carriages c 7} , the device has been made so that comb bars C ¹ C ² , rods D, combs C and bobbin carriage E are combined in one circular path around the lower point of the bar H ^{1 and} move away from each other. During this movement,. which is caused by the later to be discussed guidance of the contact strips C ³ * in the slots of coulisse C ³ , the rods DD that take the individual bars C with them are shifted by the jacquard machine according to the pattern in their longitudinal direction.

The mode of operation of the parts described here is as follows:

Assuming that the two carriages c ⁷ and E move from the front to the rear of the machine, the mutual position of the individual parts can be seen from FIG. 4A when the lower carriage c ^{7 is} in the center line, ie on the approach is to go through the warp threads c ^10. The thread c ^{9 of} the lower bobbin c ⁷ is therefore first knocked through the chain, whereupon the carriage E follows with its own e ² ; both carriages complete their movement at the same time, and at the same time the upper carriage goes up with its comb rod, so that the individual parts now assume the positions shown in FIG. The front needle bar F ² * now descends, passes between the combs CC and grabs the loops of the threads c ¹⁰ c ⁹ e ² and pulls them up to the lower edge of the bar H ¹ , during which the combs CC close, both carriages c ⁷ and E are driven forward and thus reach the position of FIG. 4A, but in the opposite sense: that is, carriage E is now on the rear comb C. If now both carriages reach their end positions on the front combs at the same time , the upper combs C diverge, the rear needle bar F ² grips the threads c ¹⁰ c ⁹ and e ² , so that with a new drive to the rear all parts return to the starting position of Fig. 4A.

As already noted, the upper bobbin carriages E are stronger than the lower c ⁷ , which the latter produce the fine tulle background, while the upper ones work with strong threads or cords. They are also further, corresponding to the separate position of the bolt C on the upper combs, further than the lower reel carriages c ⁷ from one another; in the drawing Fig. 4c and 4D corresponds to Ζ; B- an upper slide E four lower slide c ⁷ , ie on four threads c ⁹ respectively. c ¹⁰ a thread e ^{2 is} used. These threads e ² can set up their looping of the tulle threads according to the pattern of the jacquard machine, depending on the movement of the individual rods DD, so that each thread is within certain limits independently of the other by one, two, three, four etc. threads c ⁹ resp. c ¹⁰ , both to the right and to the left, as well as in opposite directions, that is, one part of the threads to the right, another part to the left (Fig. 4D). The pattern figures will stand out on both sides of the tulle background with their threads e ² .

The machine parts used to move the devices described are shown in FIGS. 1 to 3, but what is not necessary for understanding has been omitted. The frame of the machine consists of two uprights A located at each end (FIGS. 1 and 3 show it only the right one), as well as from a stand B, Fig. 2, and four smaller intermediate stands or console bearings B ^a (Fig. 2 shows only one of them), which are supported by a base plate A ^B rails A ^ and A ⁵ in solid Connection with each other.

The drive takes place from the main shaft B ⁷ , Fig. 2, equipped with pulleys B ^a , which is mounted in bearings B ²⁰ and B ^{21 of} the stands A and B, Figs. 2 and 3, and by bevel gears B ⁶ and S ⁶ * a shaft B ¹ * at the left end inclined, Fig. 2, set in rotation, the upper, not shown bevel gear engages in the bevel gear B ^{b of} a shaft B ⁱ , the latter by means of a number of thumbs attached to it all movements of the individual Produces machine parts, with the exception of the lower drive rods cc and the tie rods bb converging with them, which receive their movement directly from the main shaft B ^1. For this purpose moved the same means in the vicinity of each Endständers A crank, a connecting rod ⁹ B, Fig. 1 and 3, which is backwards articulated to the shaft on the B ^'x tight lever J3 ^10th On the shaft B ¹¹ also sit two levers £ ¹² * and b ^1, of which the former by the after "front lever continuous B ¹² ,, the front of the

the latter actuated the rear connecting rod mechanism of the lower row of slides by lever b ^{2 (Fig. ι and 4).} The tie rods bb, Fig. 3, which are moved by the levers B ¹² and b ^l , run with rollers b ³ b ³ on coulisses £> ⁴ b * and with their approaches c ¹ c ¹ articulated the two drive rods cc, which ^{at each end a lever arm c 2} , Fig. 3, inclining towards the center of the machine, which is rotatably attached to one of the rods c ³ , Fig. 2 and 3.

. Each of the arms c ³ , Fig. 2, is attached with its upper end to a lever c ^{4 swinging about axis c 5} , which is alternately raised and lowered with its nose by a thumb or eccentric ⁶ seated on shaft B *, whereby also the rods c ³ c ^{3 can put} the drive rods cc up and down accordingly in order to allow them to engage in the gaps of the latter for the purpose of the above-mentioned displacement of the lower reel carriages c ⁷ , while at the same time they themselves through the opposite oscillating movement of the levers B ¹² and b ^{1 run} back and forth. Two pair of hinge arm 1, 2 and 3, 4, which are mounted rotatably on a shaft mounted between each end stand, and a support A A A ⁶ * ^e axis, Fig. 3 and 4 serve BEZW the tie rods b. Support rods c during their movement.

All of these machine parts are used in the bobbinet machines that have been used up to now come, but they had to be taken into account here in detail, since the new added parts are closely related to them and their mode of operation only under Consideration of the whole becomes understandable.

The back and forth movement of the upper carriages E with their bobbins E ¹ from one comb to the other is achieved in the following way:

The shaft B ⁱ is provided at each end with two thumbs E ² and E ³ , Fig. 2b, of which the former actuates a lever E ⁵ equipped with a roller and oscillating with the shaft E ¹ (Fig. 2). The shaft £ ⁴ , which extends along the whole machine, carries several (four) levers Z) ¹ , each of which is articulated to the upper end of a rod Z) ² , the lower end of which engages ^{a lever D 3, which} swings about an axis attached to the intermediate stand B ^B at Z) ³ * and carries the shaft Z) ^4. This shaft is provided at each end with an arm Z) ⁵ , FIGS. 2 and 4, the roller Z) ^{6 of which runs} on an arcuate coulisse D ⁷ . The other thumb E ³ attached to .B ⁴ actuates lever E ⁵ * and its shaft E ⁴ *, whereby the lever Z) ¹ * centered on rod Z) ² * the lever D ³ * attached at Z) ³⁰ as well as the shaft Z) ⁴ * carried by the latter raises or lowers, whereby the arm Z) ⁵ arranged corresponding to the rear side runs with its roller Z) ⁶ on the coulisse D ⁷ and thus guides the shaft D ⁴ *. On the shafts D ⁴ and D ⁴ *, Fig. 4, the arms E ⁶ and E ⁶ * are attached, which serve as connecting rods and for this purpose the bars E ⁷ and E ¹ * which fit into the gaps E ^{30 of} the carriage E. wear. The movement of the bars required to drive the sledge, which is also still to be gripped. Letting go of the same lift or. must lower, should be explained by the described rotation of the shafts Z) ⁴ and Z) ⁴ * under the same guidance on the prescribed path D ^7.

On the lever Z) ¹ * a rod Z) ^{8 is also} articulated (Fig. 2), which is attached to one end of a two-armed lever Z) ⁹ , which is carried by the shaft Z) ¹⁰ and the other end one Rod Z) "moves, which is connected at the bottom with a hand lever Z) ¹² , the rear end of which ^{swings around the shaft C 6.} This arrangement is used to be able to lift the strips E ¹ * by pressing down the hand lever Z) ^{12, if necessary} If new bobbins or bobbins are inserted, it should be necessary to remove the carriage E.

In order to allow the upper comb catches to diverge while the thread loops are being picked up by the needles, as already noted above, grinding pieces on the comb rods, so-called. Stones C ³ * C ³ * attached, which slide in semicircular slots of the segments C ³ C ³ attached to the frame of the machine, the hinge levers 5 and 6 swinging around A ⁶ * serve for support and security. Furthermore, a rod C ^{4 is} attached to each end of the front comb rod C ^1, FIGS. 2 and 3, the upper end of which is rotatably connected to a lever C ^{5 attached to the shaft C 6;} the shaft carries a lever C ⁶ C ^7, which is bethätigt through the shaft to B * seated thumb C ^8, Fig. 2 a, and the wave C ⁶ BEZW. the comb rod is set in corresponding vibrations. ^{A rod C 4} * is attached to the rear comb rod, which is connected at its upper end to the lower arm of an angle lever C ^{5 * which is also rotatable on shaft C 6} , the upper arm of which is supported by another thumb C ⁸ * sitting on shaft B ^1. is actuated. With this arrangement, the comb rods are lifted and / or lifted in a manner corresponding to the rotation of the thumb in the slots in the segments C ³ C ^{3 that} guide them. lowered and, since these slots are concentric with the lower edge of the strip H ¹
