WILHELM VOGEL in TRIBERG (Baden). Straw braiding machine.

Patented in the German Empire on May 28, 1879.

In the accompanying drawing, FIG. 1 is the side view, FIG. 2 is the basic outline, FIG. 3 the front view; the remaining figures are details of the machine. The mesh strip is clamped by the five-edged properties prism cde from fixed and horizontally; so that four blades 1,2,3 ^un d 4 and three blades 5, 6 and 7 are directed perpendicularly to each other and horizontal. The prism abcd * is pressed downwards onto the strip by the spring i and is in the guide of the cylinder surrounded by the spring i , on which the prism can be moved up and down with the two side levers k, FIGS. 1 and 2 . L is a power cylinder which is rotated by the wheels mm '; on the same are the depressions η , in which the pins of the levers o, o. ₂ O ₃ and f., are pushed back and forth by the curves made in the depression, the developments of which can be seen in FIG.

The braiding itself is done with the angle levers k and the segment-shaped levers p. There is z. For example, in the case of a seven-stemmed braid, as shown here, the fact that the outer stem is placed once on the left and once on the right side around the next one below and over the other two; in Fig. 2 z. B. first goes around stalk 1 under stalk 2 and lays itself over 3 and 4 close to 5 in the same plane; once this has happened, blade 7 makes the same movement; he goes around under 6 and lies down again on the same level close to stalk 4, and so on

At the beginning of the braiding, the cylinder Z, Fig. 1 and 2, rotates in the direction of the arrow, Fig. 3. The pin o ,, Fig. 2, moves with the lever arm O ₁ backwards; as a result, the levers k, FIG. 1, are pressed downwards and a break (see FIG. 5) is pressed into the stalk 1. The table top itself has the appropriate recess for the break; at the same time the stalk 2 goes up to 60 ° through the lever qr, Fig. 1 and 3. The arm al, Fig. 6, is fixed to kk and pushes q downwards; qr moves around the pin s, Fig. 1, 3 and 6. At R, Fig. 1 and 2, there is a fixed journal bearing for the angle lever k. When k and stalk ι return to their previous position, pin o. _X , Fig. 1 and 2, goes forward, and the round lever /, Fig. 2, grasps with its claw, Fig. 7, the stalk 1 and guides it up to bc, close to and in the same direction with stalk 5. Stalk 2 is now on top, stalk 3 and 4 below. The straw strip must now go back around the braided stalk 1, and the same thing is repeated on the other side. The strip retreats alternately in the direction cd and cb, FIG. 2.

The retractor / is pulled backwards again by a curve in L , but at the same time deflected laterally by the two springs //, FIG. 2, alternately once to the right and once to the left at 45 °; This happens as follows: As soon as the walking backwards from / begins, an increase I, FIG. 9, at q in FIG. 1 comes into effect on the wave L at the same time. As a result, the same goes up with the square and the comb and holds the strip under the prism cde, similar to the stuff of a sewing machine; at the same time, 11, Fig. 2, goes up, and holds the square in the line b Z ₁ resistance. The spring 11 remains calm, while ή ή by u ti, Fig. 8, was taken up with. The retractor goes in this way first upwards, then backwards at 45 °, and quickly back to its previous position, and the strip of straw is clamped back onto the table by ab cde. Braiding then begins on the other side; in this case, the spring 11, FIG. 2, rises with / through another elevation on shaft L in the air. The retractor must then step back into the lower position. All levers run in the middle guide, Fig. 10, and / is held by the spring, Fig. 8.

Another job of the machine is inserting the stalks; because a stalk is braided, so the latter must be replaced by a new one. Unlike braiding by hand, the stalks do not become random long to the end, but braided from exactly the same length. As soon as the straw strip braided and inserted, the stalks must be proportionally decreasing in length. Of the the shortest about 4 cm, the first 6 cm, the third 8 cm and so on.

If a new stalk is necessary after weaving both sides four times, so the inlay roller turns once, while the drive roller makes four turns, etc.

The whole straw is inserted as follows:

The straw container v, Fig. 2, it and .12, consists of a wedge-like pointed sheet metal box ν ν, Fig. 2. The lower edge protrudes a stalk thickness from the table so that only one stalk can pass through.

A shaker w, Fig. N, causes the straw to be correctly positioned by its upward and downward movement, so that at all times a stalk lies below in the apex. Under the straw container is the roller X, Fig. 2 and 12, which receives its rotation from the shaft L, Fig. 2, and has a recess y in which the pin of the insert ζ runs. In Fig. 13, the insert ζ is seen from above. It forms a pair of pliers, the arms of which are held apart by a spring. At I, I, Fig. 13, the pliers are pulled through two edges protruding on both sides with their two bevels, as a result of which they pick up and grasp the lowest stalk with the two forks ", Z ₁ , Fig. 13. The Insert ζ is now brought forward by the curve y , so that the stalk at z>, k ,, Fig. 2, is brought to the edge cb . This happens exactly at the time when the stalk 2 rises, the break in the stalk 1 is made and before the stalk 1 is braided. The new stalk only arrives when it is to be worked into it using the lever ρ. If the lowest stalk is now pushed forward through the insert ζ , it releases the stalk and goes back; this happens because the increase s 1, FIG. 12, hits the two resistors II, II, FIG. 13 a, and the pliers move apart and empty; Once in the earlier position, it is returned to the two side resistors II by the pressing spring. The step of the depositor is as follows: At the beginning of the forward movement he closes, grabs the stalk, pulls it forward, lets go of the stalk and goes back empty.

The straw container is closed at the bottom by a light sheet metal spring V ₁ , FIG. 11. While the machine continues to weave a few times, a new straw is placed in the lower corner of the straw container.

If the netting is made from once or twice divided straw, or otherwise from wood fibers, etc., this straw container is no longer sufficient; then the material is fed in a different way. In Fig. 15 there is an endless wire mesh which rotates around two rollers. This wire mesh has sections on its surface, into the depressions of which a stalk is placed by hand and is guided up to the braided edge bc, FIGS. 2 and 15. This movement is brought about by the drive shaft through transmission; the depositor ,. Fig. 16 is the same as in Fig. 12, only here it is reversed. As soon as a stalk is necessary, it is turned in the direction of a by the peg c _% , Fig. 16, which runs in a curve. ₂ advanced; the latter goes up through the resistance b%, Fig. 16, then goes together through the resistances III, III on both sides, grabs the stalk, quickly guides it into place, goes up through the slope d _% , releases it III unplug the tongs, let go of the stalk, and, pressed by a spring, goes back empty to its former position.

The machine's system can be used for any type of braid. It will be from both of them every time Pages alternately the outermost stalk under the initially adjacent stalk around the bottom laid the stalks next to it.

For this purpose I sheet drawings.
