Crochet machine for decorative thread trimmings.

Patented in the German Empire from May 4th 188g.

In the previously used crochet machines for decorative thread trimmings, the setting is one new pattern with great expenditure of time and the number and variety of possible pattern a very limited one.

The machine forming the subject of the present invention is intended to remedy this disadvantage and for this purpose is equipped with a jacquard machine, whose sinkers act on the thread guides.

Fig. Ι the accompanying drawing shows the machine in the front view, Fig. 2 in the Side view from the right and FIG. 3 seen in the side view from the left.

• Fig. 4 shows the machine in an axonometric view.

Figure 5 shows a pattern made by the machine and Figures 6-11 illustrate the making of this pattern.

In the inclined crossbars a, Fig. 2 and 3, the thread guides / supporting rods b are mounted displaceably, which engage with the arms c between the bars of the guide grate d and can only rotate about their axis as far as is necessary to let them pass each other.

On the rods b two adjusting rings b ^l & ² , Fig. Ι and 4, are attached, between which the rod b encompassing the tabs of the push rods ^ are moved back and forth according to the pattern, the magnitude of the displacement by adjusting the adjusting rings can be changed.

The movement of the push rods is done according to the pattern by a jacquard machine in the following way:

The rods \ are attached to the arm h of the three-armed angle lever rotatable about the common axis χ.

The arms h ¹ h ^{2 of} these levers are connected by cords or wires u to the sinkers ρ of a jacquard machine, which contains twice as many sinkers as there are guide rods b , since one sinker for left and a second for right movement the rod in question is required.

The sinkers ρ are lifted by a knife m in the same way as with the loom, if they are not pushed back by the jacquard card r and by means of the needles η in a known manner, as soon as the drawer Z carrying the card prism e mediates the arm i attacking pull rod i ¹ , which is actuated by the needle movement eccentric not specified here, strikes against the needles η.

The up and down movement of the knife m in the guides t is brought about by the lever k , which is driven by eccentric ο and engages the crosspiece q, through the intermediary of the rod g carrying the knife m .

If a certain line guide is to be moved during a tour of the meshes, the needle η belonging to the corresponding sinker will find a hole in the abutting card so that it penetrates into the prism e ... and does not push the sinker back, whereby that

Messer lifts the board and, with the help of the parts uh ¹ respectively. h ² h qnd \ causes the movement of rod b.

When changing the pattern one only has to put another jacquard warp on the prism e , which can be done in a few seconds.

The process of making the trimmings results from the following:

While the latch needles s process the threads v ¹ inserted through the perforated needles ν like in a chain chair into wales, the cords ι

2, 3, 4

and 5 of those by the jacquard machine activated cord layers inserted and thereby integrated.

From the latter, ι and ι ^{x are moved} evenly and each lay their cord only over three needles, the cord layers 2, 3, 4 and 5, on the other hand, lay their cords over all six needles and then, after making the respective rows of stitches, as those in Fig. 5 are numbered, one after the other in the positions shown in FIGS. 6 to 11.

If we start from the position in FIG. 6, where all the line layers are on the right, then the guide 3 moves to the left over all the needles and places his line over all six threads, FIG. 7a; In Fig. 7b the knitting needles s have advanced over the cord 3 to the perforated needles ν , in Fig. 7c the perforated needles have inserted their threads into the hooks of the knitting needles and in Fig. 7d the knitting needles have moved back again and still worked six stitches on cord 3.

In the second knitting tour, the cord layers 3 and 2 are on the left, FIG. 8, and the cord 2 is involved.

In the third tour, the guides i ^x , i, 2 and 3 are on the left, FIG. 9, and the cords i ^x and ι are worked in by three needles each.

In the fourth tour, the guides 1 * and ι are again on the right, FIG. 8, and the cords i ^x and ι are tied for the second time.

In the fifth tour, the guides i ^x and ι are again on the left, FIG. 9, and the cords 1 ^x and ι are set for the third time.

On the sixth tour, the guides i ^x , i, 2, 3 and 4 are on the left, FIG. 10, and the cord 4 is incorporated.

On the seventh tour, all guides are on the left, Fig. 11, and line 5 becomes bound.

On the eighth tour, the guides stand, as shown in FIG. 10, and the cord 5 is again involved.

The ninth tour corresponds to Fig. 9,

the tenth tour Fig. 8,

the eleventh tour Fig. 9,

the twelfth tour Fig. 8,

the thirteenth tour Fig. 7 a,

the fourteenth tour Fig. 6, and, it will here, as can be seen above, each time the cord was tied in, which was laid last became.

Claims (1)

Patent claim: A crocheting machine for decorative thread trimmings, the decorative thread guides of which are individually moved back and forth over the wales formed by the latch needles by sinkers of a jacquard machine, in that the drivers (\) of the guide rods (b) between adjusting rings (b ¹ b ² ) of the the latter, depending on the distance between these adjusting rings, emptied over distances of different lengths. For this purpose 2 sheets of drawings.
