PATENT OFFICE.

In the case of ribbon looms, as is known, several ribbons are woven simultaneously in so-called aisles arranged next to one another and the lower log is essentially set up as shown in FIG. 1 of the accompanying drawing. There are several rifle lane parts a _x a receiving loading wheels d next to each other in the same. ₂ a ₃ . . . a _{n + l} provided, between which the sheets belonging to each aisle b ₁ b. ₂ b ₃ . . . b _n are located. If the drawer is arranged for η corridors, then in it there are "leaves b _x b. ₂ b ₃ ... b _n and η + -ι rifle course parts with a total of w riflemen C ₁ c ₂ C ₃ ... c “; All the shooters are positively connected to each other in that the loading wheels d engage on the one hand in a toothing provided in the lower part of each shooter, on the other hand in a rack e which is arranged displaceably in the lower loading block and extends along the entire length of the drawer.

In Fig. Ι the accompanying drawing, this rack is intended in its outermost position on the left; the outermost rifle lane Ci ₁ is empty, while all the others have one shooter each C ₁ C ₂ c ₃ . .. C _n included. If the rack e is now brought into its outermost position on the right, all the shooters move from a. ₂ after U ₁ resp. from a ₃ to a. ₂ etc. and the last rifle lane a _{n + 1} becomes empty. With each aisle, since the shed is open at this moment, the thread is inserted, whereupon the store stop takes place. After the formation of the next compartment, the rack e is now brought to the left, whereby all the shooters return to the position shown in FIG.

The drive devices used up to now for the rack e are set up in such a way that the stroke of the latter always remains the same and is only sufficient to move the shooters between two adjacent shooter tracks, i.e. each shooter can only use A ₁ or A _{2 in one aisle} or A ₃ etc. work. But since similar patterns of the same fabric are usually woven in the different aisles of a chair, which differ only in color, it immediately becomes clear that one could weave ribbons of different colors without having to resort to expensive swap shops, if the shooters take turns in different gears could be transferred.

Let us explain this with a simple example:

There are the following two-tone patterns of the same color repeat of a fabric weave: two patterns blue and white and two patterns white and red; the list of the Chair would then be as follows:

The four chain strands, which can be multicolored and also differently colored from each other, are drawn into the aisles A ₂ A ₃ A ₄ A _h , while the aisle A ₁ remains empty. The Schützenbahn a. ₂ receives a shooter C ₁ with white, a " such a C ₂ with blue,

a _i such a C ₃ with white, a. such a C ₄ with red, a ₆ such a c ₅ with white thread, while the rifle tracks U ₁ and a ₇ remain empty; the shooters C ₁ C ₂ C ₃ C ₄ C ₅ work accordingly in the gears A ₁ A ₂ A ₃ A ₁ A ₅ ; since the passage A _{x is} empty, shooter C _{1 works} empty, ie without consumption of weft thread. The gears A ₂ A ₃ A ₄ A _% get respectively. blue, white, red, white thread; At the end of this color repeat the shooter drive device is now controlled in such a way that the shooters C ₁ C ₂ C ₃ C ₄ C ₅ now respectively. work in the corridors A ₂ A ₃ A _t A ₅ A ₆ , the shooter C ₅ then works empty, since the corridor A _{6 is} empty, as is the corridor A ₁ . The position of each shooter in front of each creation in the two color repeats results from the following table:

A ₁ (blank) A C ₁ white C ₁ white
C ₂ blue First C ₂ blue

whereby the last Schufs of each color repeat is a straight Schufs.

The present invention is a gunner drive device, which such Relocation of the shooters from one gear to another at the end of a color report automatically effected.

In the accompanying drawing, an example embodiment of the subject matter of the invention is shown, namely:

Fig. Ι a view of the lower part of a chair drawer,

Fig. 2 is a front view of the entire device in the rest position,

Fig. 3 is a vertical section of the same through line AA (Fig. 2),

4 shows a front view on a larger scale, showing a working position of the device illustrates;

Fig. 5 to 7 are different working positions of a drive device for a Relocating the riflemen by a corridor,

8 a to 10 b different working positions of a drive device for three relocations.

The frame B , in which the carriage C can slide up and down, is attached to the loading arm A. On the front side of the frame B , the two guides EE ^{1 are} attached, into which the rulers FF ^{1 are} loosely inserted; At their upper end, these rulers FF ¹ are connected to one another by a cord / cord running over a loose roller G which is carried by an extension H of the frame A. At their lower end, the rulers FF ¹ are in turn connected to one another by a chain J, which runs over the chain wheel M carried by the support K on the lower loading block L. On the back of the sprocket M sits firmly the gear N, which engages in the aforementioned rack e. The two rulers FF ¹ are usually pressed against each other by springs OO ¹ and each of them is respectively ^{with two notches P 1} P ^3. P ² P ⁴ , in which the pin Q carried by the carriage C can fall. This carriage C is moved up and down by the shutter drive shaft in the frame A , namely once down and up again in front of each shutter stop. As the pin Q. falls into one of the notches P ¹ P ² P ³ - P * when the carriage C goes down, it takes one of the rulers FF ^{1 down} with it, causing the chain wheel M, the gear wheel N and the rack e to move be caused in a sense. When going up, the pin Q, overcoming the force of the springs OO ¹ , spreads the rulers FF ¹ apart,

without taking them with you. On the guide E , the lever R is rotatably arranged about the bolt S ; the two wires TT ¹ , which are bent at a right angle towards the frame B, extend from this lever at their free end; in the normal position of the lever R, ie when the same is symmetrical to the line AA , the bent ends of the wires TT ¹ each engage between one of the springs O O ¹ and a ruler F respectively. F ¹ , but without affecting the springs or the rulers. A pull cord UU ¹ goes from each end of the lever R to a sinker of the jacquard machine.

The device works as follows:

Let the contactors C ₁ C ₂ C ₃ ... C _{n be} in the position illustrated by FIG. 1 and the drive device in the middle position illustrated by FIG. 2; the drawstring U ^{1 is} now drawn to the jacquard machine; the wire pushes against the ruler T F, the action of the spring O supportive, while the wire T ¹ lifts the pen from the rulers O ¹ F ¹ (see FIG. 4.); the rulers FF ¹ then move into the position illustrated by FIG. 4, for which the notch P ^{1 of} the ruler F is in the path of the pin Q. When the carriage C then descends, the ruler F is carried along by the pin Q , while the ruler F ¹ , attracted by the pull cord /, moves upwards. As soon as the pin Q has fallen into the notch P ¹ , the tension on the cord U ¹ continues and the rulers FF and lever R are brought back into a symmetrical position with respect to line A -A by the springs OO ^1. As the slide C goes down, the chain wheel M, gear wheel N, rack e and all the shooters C ₁ C ₂ C ₃ move. . . C _n in the sense of arrows 1 (Fig. 2). When the slide has reached its lowest position, the shooters C ₁ C ₂ C ₃ ... C _{n are also} from the rifle lane parts a ₂ a ₃ a ₄ . . . a _{n + l} in those U ₁ a ₂ a _a . . . a _n arrives, whereby the rifle lane part a _{n + l} becomes free. The notch P ^{2 of} the ruler F ¹ occupies the earlier position of the notch P ⁴ , while P ^{1 takes} the earlier position of P ³ . The carriage C and with it the pin Q now goes back upwards, spreading the rulers FF ¹ from one another, into its starting position and snaps into the notch P ² (see FIG. 5). At the next downward movement of the pin Q. this takes the ruler F ¹ with it without the involvement of the cords UU ¹ , and the whole shooter mechanism moves in the opposite direction to the arrows 1 and comes to its original position Fig. 1 and 2. After going up of the carriage, the cord pull U ¹ ; tightened (Fig. 4) and continued the same game until the color change is to occur.

On the assumption that the number of shots in a color repeat is even, At the end of such a device, the whole device is returned to that illustrated in FIGS. 1 and 2 Be able to d. H. in the starting position.

Now the first card of the following color repeat is arranged in such a way that it causes the pulling of the cord U; It follows from this that the rulers FF ^{1 come} into the position illustrated by FIG. 6, as a result of which the pin Q now falls into the notch P ^{i instead of into the notch P 1} (see FIG. 6) the whole shooter drive mechanism is driven again in the same sense as in the previous shooting and the shooters C ₁ C ₂ C ₃ ... C _n instead of Ci ₁ a. ₂ a ₃ ... a _n now to a ₃ a _i a _& ... a _{n + l} move when the next low-going of the carriage C of the pin (Fig s. 7.) falls Q. without the participation of cord coatings UU ¹ in the notch P ³ in;. for all this colors rapport operate the notches P * P ³ instead of P ¹ P ² , ie the shooters work in corridors A. ₂ A ₃ A ^... A _{n + 1} , the latter being empty instead of A ₁ A ₂ A ₃ ... A _n . Always on the assumption that the number of shots of the color repeat is even, at the end of the same the whole device is again in the L illustrated by FIGS. 1 and 2 age have reached; then the next sample card will again cause the pull cord U ^{1 to be} tightened and a return to the color repeat /.

It should be noted that only every odd card in a color repeat causes the pulling of one of the cords U or U ^1; No actuation of these cords is required for the straight shots, as one can see for oneself when looking at FIGS. 5 and 7.

If the number of shots in a color repeat is odd, the shooters C ₁ c ₂ C ₃ ... C _n in a _v a come for the first shot. ₂ a ₃ . . . a _n to lie; at the end of the color repeat, ie after the 2 »i + i ^th firing, they are then again in the rifle tracks a ₂ α _Ά a _t . . . a _{n + 1} , as illustrated in Fig. 1, and the 2m + 2 "card then causes a lift. The shooter in the same sense as in the 2m + 1 ^th Schufs, ie in the opposite sense to the arrow 1, as explained before. Instead the two gears a ₁ and a _{n +} BEZW to leave _one empty. on a chair with "transitions η -2 programs to use for weaving, it will naturally be more advantageous, both on the left and on the right end of the lower

Loading block L above the outermost sheets b _r and b _{n to attach an excess shooter track, which the shooter C 1} or not belonging to this report on every second shot of a color report. C _n (white in the example mentioned).

It is of course also possible to move the shooters several times in the same direction by one gear; for this it is only necessary to provide the rulers FF ¹ with a corresponding number of notches. With three notches in each of the rulers FF ¹ , the shooters can be shifted two times in the same direction by a course and thus three-colored patterns are woven; In this case, however, the number of shots of each color repeat must be odd, as is evident from FIGS. 8a to 8b. With all odd shots of the first color repeat, the pin Q falls into the notch in the ^{ruler x 1 of} the ruler F, with the even shots, however ^{, it falls into the notch x 2 of} the ruler F ¹ (see FIGS. 8a and 8b). At the end of this color repeat the rulers are in the position illustrated by Fig. 8b (position after an odd or in front of an even scratch), but they are controlled in such a way that the pin Q. must ^{fall into the notch x 3} (Fig 9 a), the shooters are shifted by one gear by being actuated in the same way as with the last shot of the first color repeat (see Fig. 8 a and ga). The same thing happens with the transition from the second to the third color repeat (see Fig. Ga and ioa).

In FIGS. 5 to lob, the pin Q. is in thought of its supreme position; from these figures it can be seen in which of the notches he comes to mind for the next villain; it can be derived from this on the related sense of movement the riflemen were asleep.

This rifle drive device can be used not only on simple, but also on double and swap shutters, ie with those with two rows of rifle tracks arranged one above the other, it is only necessary to connect the two rack racks e with each other. In the case of swap shops, there would be a shooter drive device according to the present invention for each row of rifle tracks. With such a drawer, the shooters could change in two directions: on the one hand, by alternately starting the various rows of shooters and, on the other hand, by moving the shooters in one row from one aisle to another.

The illustrated embodiment is not intended to be binding, but rather serves to explain the concept of the invention using a concrete example. The rulers FF ¹ with the notches P ¹ P ² P ³ P *, the slide C with the pin Q, the lever R with its two wires TT ¹ and the gear MN can be replaced by other equivalent parts. Let us therefore introduce the more general designations switch hook carrier ⁷ instead of rulers FF ¹ , switch hooks instead of notches P ¹ P ² P ³ P ⁴ , switch element instead of pin Q, gripper instead of wires TT ¹ .

Claims (1)

Patent claim: A shuttle drive device for ribbon looms controlled by the jacquard machine, which allows the shooters to be shifted from one gear to another, characterized in that the usual shift hook carriers (FF ¹ J instead of just one shift hook each with a row of such (x ¹ x ³ x ⁵ ... or X ² X ⁴ X ⁶ ...,) and by means of two grippers (TT ¹ J in one for the engagement of a switching element (Q) in one of the switch hooks belonging to this carrier can be brought into a suitable position for the purpose of actuating the rack rack periodically two times one after the other in the same sense and thus being able to move all the shooters by one gear in the drawer. 1 sheet of drawings.
