Die Erfindung betrifft einen sowohl einseitig als auch auf beiden Webstuhlseiten anbringbaren Schützenwechsel mit Hubkästen, bei welchem die Verstellung der Wechsellade in bekannter Weise durch die Platinen einer Mustervorrichtung unter Vermittlung zweier nach entgegengesetzten Richtungen sich bewegender Messer bewirkt wird, von denen das eine Messer die Hebung, das andere die Senkung der Wechsellade herbeiführt.The invention relates to a loom that can be attached both on one side and on both sides of the loom Change of shooters with lifting boxes, in which the changeover drawer can be adjusted in known way by the boards of a sample device with the mediation of two knife moving in opposite directions, of which the one knife raises the drawer, the other lowers it.

Dieser Schützenwechsel kennzeichnet sich im wesentlichen dadurch, daß die Wechselplatinen 8 mit einer Reihe von Hubkörpern, die als schwenkbare Schlitzexzenter ausgeführt sind, in Verbindung stehen, zwischen welchen parallel bewegliche Gleitstücke angeordnet sind, deren jedes durch das eine der beiden, dem betreffenden Gleitstück benachbarten Schlitzexzenter verstellbar ist und die Drehachse für das andere dieser Schlitzexzenter trägt, wobei das erste Exzenter der ganzen Reihe um eine feste Achse drehbar ist und das letzte Exzenter mit der Wechsellade in Verbindung steht. Bei entsprechender Bemessung der Schlitzexzenter wird durch die vorbeschriebene Anordnung erzielt, daß beim Ausheben eines der Schlitzexzenter die Wechsellade um einen Schützenkasten gehoben oder gesenkt wird, während durch gleichzeitiges Verstellen mehrerer oder aller Schlitzexzenter zufolge Summierung ihrer Hubwirkungen die Wechsellade in verschiedenem Maße verstellt bezw. mit .jedem ihrer Schützenkästen in die Ladenbahn gebracht werden kann.This change of shooter is essentially characterized by the fact that the exchangeable sinkers 8 with a number of lifting bodies designed as a swiveling slot eccentric are in connection, between which parallel sliding pieces are arranged, each of which through one of the two slot eccentrics adjacent to the slider in question is adjustable and carries the axis of rotation for the other of these slot eccentrics, wherein the first eccentric of the whole series can be rotated around a fixed axis and the last eccentric is connected to the removable drawer. If the slot eccentric is dimensioned accordingly, the above-described arrangement achieved that when one of the slot eccentrics is lifted, the removable drawer is raised or lowered by a contactor box, while by simultaneous adjustment of several or all slot eccentrics resulting in the summation of their lifting effects the changeable drawer adjusted to different degrees respectively. with each of their contactor boxes in the store lane can be brought.

In Fig. ι der beiliegenden Zeichnung ist ein derartiger Schützenwechsel mit vier Hubkästen im Aufriß dargestellt, wobei sämtliche Platinen und die mit denselben verbundenen Teile aus ihrer Grundstellung ausgehoben erscheinen. Fig. 2 ist ein nach der Linie A-B in Fig. 1 geführter senkrechter Schnitt und Fig. 3 ein nach der Linie C-D in Fig. 1 geführter Horizontalschnitt. Die Fig. 4 bis 7 zeigen die den vier Stellungen der Wechsellade, entsprechenden Stellungen der Schlitzsegmente und der mit denselben in Verbindung stehenden Teile.In Fig. Ι of the accompanying drawing, such a shooter change with four lifting boxes is shown in elevation, with all the boards and the parts connected to them appear to have been lifted out of their basic position. FIG. 2 is a vertical section taken along the line AB in FIG. 1, and FIG. 3 is a horizontal section taken along the line CD in FIG. 4 to 7 show the four positions of the interchangeable drawer, corresponding positions of the slot segments and the parts connected to the same.

Die Beeinflussung des Schützenwechsels erfolgt, wie angegeben, mittels einer Jacquardeinrichtung, deren Kartenzylinder 1 in festen Lagern drehbar gehalten ist. Die Nadeln 2 dieser Jacquardeinrichtung sind in Führungen 3 verschiebbar, und jede dieser Nadeln ist an dem rückwärtigen Ende mit einem Schlitz versehen, durch welchen der aufrechte Arm 4 eines zugehörigen Klinkenhebels 5 dringt. Die Klinkenhebel sind bei 6 an den zugehörigen Führungsstangen 7 für die durch die letzteren dringenden Platinen 8 der Jacquardeinrichtung angelenkt. Die in dem Webstuhlgestell horizontal geführten Stangen 7 stehen unter Druck von Federn 9, welche bestrebt sind, die Platinen nach rechts gegen die Nadeln hin zu drücken.The change of shooter is influenced, as indicated, by means of a jacquard device, whose card cylinder 1 is rotatably held in fixed bearings. The needles 2 this jacquard device are slidable in guides 3, and each of these needles is on the rear end provided with a slot through which the upright arm 4 of an associated Ratchet lever 5 penetrates. The ratchet levers are at 6 on the associated guide rods 7 for those penetrating through the latter Hinged sinkers 8 of the jacquard device. The horizontally guided in the loom frame Rods 7 are under pressure from springs 9, which strive to move the sinkers to the right to push against the needles.

Unterhalb der Klinkenhebel 5 ist ein Stecher 10 angebracht, welcher von einem bewegten Teil des Webstuhles aus in schwingende Bewegung versetzt wird. Bei der Bewegung des Stechers 10 gegen die Platinen hin nimmt derselbe diejenigen Klinkenhebel 5 mit,Below the ratchet lever 5, a piercer 10 is attached, which of a moving part of the loom is set in swinging motion. When moving of the piercer 10 against the sinkers, the same takes those pawl levers 5 with it,

Claims

which, as a result of the entry of the associated needles 2 into the card holes, are lowered, while the other ratchet levers, whose needles hit full card positions, are raised and therefore remain unaffected by the engraver. On both sides of the rows of boards two knives 1.1 and 12 are arranged, which move up and down in opposite directions. The knife 11 takes on its upward movement all sinkers, which are held in the right-hand basic position by the springs 9, with upwards, while the second knife 12 in its downward movement through the Stecher takes the plates adjusted to the left downwards.

Each ratchet lever 5 has a reinforcement 5 'on its underside, onto which the engraver acts on its return movement, whereby the

ao lowered ratchet lever is raised again and the associated needles are removed from cylinder 1 be pulled out, which latter can now be rotated.

The device described so far is known and does not form part of the present invention. The latter consists of the following: The plates 8 are connected to associated pivotable slot eccentrics α, b and c, for example by a lever 14 pivotable by 13 and a handlebar 15 each. Between the mutually identical slot eccentrics a, b and c, sliding rods g and h are arranged in fixed guides τ6 parallel and displaceable in the longitudinal direction.

The first slot eccentric α of the "series is mounted in the loom frame at 17, and a bolt 18 seated on the adjacent slide bar g engages in the slot of this eccentric, advantageously by means of a slide roller. This slide bar carries the pivot pin ig for the second eccentric b. In the slot of which engages a roller bolt 20 carried by the second slide rod h . The slide rod h carries the pivot bolt 21 for the third eccentric c, in whose slot the roller 22 of an angle lever 23 pivotable by 13 engages, the second arm of which with the changeable drawer or with the is connected to the same leading linkage.

The said slot eccentrics are now dimensioned so that each of the same during its adjustment through the intermediary of the angle lever 23 raises or lowers the changeable drawer around a contactor box. Now that the drawer is in their basic position holds a contactor box in the store lane, so are when the removable drawer for example, as assumed, contains four contactor boxes, three adjustments of the Removable drawer, accordingly three slot eccentrics and three sinkers are necessary to each of the four To be able to bring contactor boxes into the store lane.

In general, there will be as many slot eccentrics and sinkers as there are corresponds to a reduced number of contactor boxes in the removable drawer.

It is now the mode of operation of the device described on the hand of Figs. 4 to 7 will be described in more detail.

As soon as the drawer is in the basic position and holds the first contactor box in the store track, all eccentrics are with their slotted part (Fig. 4), but the sinkers are lowered and the angle lever 23 assumes position I. If the slot eccentric c is pivoted from the basic position shown in FIG. 4 by lifting the respective plate 8, it brings the angle lever into position II (FIG. 5), in which the second contactor box is engaged. If the slot eccentric b is also pivoted (FIG. 6), the same effects a displacement of the slide rod, including the slot eccentric c, to the left, so that the angle lever 23 is brought into position III, in which the third contactor box is engaged. If finally the slot eccentric α is also pivoted (Fig. 7), the same causes the displacement of the two slot eccentrics b and c and the slide rods g and h as a whole to the left (Fig. Τ and 3), so that the angle lever 23 in the Position IV is brought, in which the fourth contactor box is engaged. This position of the parts was based on FIG.
