Definitions

the aim of the invention is a simple and economical solution in which the shed formation is preferably carried out by means of rotary shaft machines and in which no shutting down of the shed is necessary for the control.
the dobby has two known lifting units 1 and 10 of the rotary shaft type, for example according to CH-PS 517192. These units each consist of a drive shaft 2, on which an eccentric disc 3 is rotatably mounted, which in turn is rotatably seated in the connecting rod 4 and has a wedge 5 which is radially displaceable to the drive shaft 2 or to the eccentric disc 3 and by a control element, not shown , for example according to CH-PS 517192, is pushed back and forth so that it couples either with the drive shaft 2 or with the connecting rod 4.
the lifting unit executes a working movement, ie the differential lever 6 is pivoted via the connecting rod 4, one lifting unit 1, 10 engaging at each end of the beam-like differential lever.
the connecting rods 4 of the two lifting units 1, 10 are in the low position.
the differential lever 6 is also in the low position 26 and is parallel to the drive shafts 2.
the pin 11 of the bracket 12 is located obliquely below the pin 13.
the shaft 17 has the high position 18.
the wedge 5 of the lifting unit 1 is not controlled to engage with the drive shaft 2. During the subsequent rotation of the drive shaft 2 of the lifting unit 1, it does not perform any working movement. The dobby remains in the position shown in FIG. 2.
the wedge 5 of the lifting unit 1 is controlled to engage with the drive shaft 2.
the lifting unit brings the second end of the differential lever 6 into the elevated position (FIG. 3).
the differential lever 46 is now again parallel to the drive shafts 2, but at a higher level.
the rocker arm 7 is pivoted further up to the position shown in FIG. 3.
the tab 12 is also pivoted up, which corresponds to a pivoting back of the angle lever 15 from the position shown in FIG. 2 into the identical position shown in FIGS. 1 and 3.
the shaft in turn reaches the high position 18.
the angle lever 15, in spite of the three control positions of the differential lever 6, takes only two end positions without an intermediate stop.
the one pivot pin 11 of the bracket 12 must perform a movement 20, in this case an up and down movement, which is approximately perpendicular to the direction of movement 21 of the second fastening bolt 13 of the bracket 12, in this case horizontally.
the dobby according to FIG. 4 in turn has two lifting units 1, 10, the drive shafts 2 of which alternately rotate by half a turn.
the ends of the differential lever 6 are articulated at the connecting rods 4.
the rocker arm 70 engages, as in FIGS. 1-3, again in the middle at 8 on the differential lever and is provided at its free end with a curve 22 which has a cam 220 approximately in its central region.
the free end 130 of the angle lever 150 bears against this open cam curve 22, 220 under the force of the spring 24.
the lifting units 1, 10 are in the low position of the connecting rods 4.
the free end 130 of the angle lever which is provided with a roller 23, lies against the cam curve 22 above the cam 220.
the shaft 17 is lifted into the high position 18 via the lifting linkage 150, 16.
FIG. 5 corresponds to the example according to FIG. 4, except for the open cam curve, which is replaced by a cam curve 222 designed as a groove.
This lever is connected directly to the shaft 17.
a spring on this single-arm lever is no longer necessary because the lever is inevitably guided through the curve as a groove.
the pattern-based control of each wedge has at least the duration of a weft or a full revolution of the main shaft of the loom, since the two lifting units are independent of the next requested shaft position - unless there is none Change of position of the shaft - always work alternately.
the central articulation point 8 of the differential lever 6 assumes three working positions 26, 36, 46, the shaft 17 with the central working position 36 basically in one specialist position, e.g. Low position 19, and with the two extreme or external working positions 26 and 46 basically in the other position, e.g. High position 18, is controlled.
the control can also take place in reverse.
This different control with respect to high and low shed represents one of the essential differences of the present dobby compared to the known, so-called three-position dobby.
