    This invention relates to a rotation dobby having a key coupling between a drive shaft and an eccentric device for the movement of the heddles, the key being mounted under spring action in a radially extending recess in an eccentric disk arranged in a crank arm and being engageable and disengageable in accordance with a pattern into and out of an axially extending groove of the drive shaft at two diametrically opposite coupling places by means of a shift rod which can be controlled in accordance with a pattern and engages via a coupling member into a groove of the key which is open in the axial direction of the drive shaft. In order to simplify the engagement and disengagement, the key is pressed, in engaged position, by a compression spring into the groove of the drive shaft, the spring force of the spring being greater than the centrifugal force which acts on the key during revolution, two spring-loaded lock slides which receive the outer end of the disengaged key between them being provided on each crank arm at each coupling place.

The latch pin 5 (Figs. 7 and 8) is fixed between two locking sliders 25 and 26, which are located on the axles 27 fixed on the connecting rod and can be rotated in the direction opposite to the action of the compression spring 28. The blocking sliders 25 and 26 also have an upslip surface 29, which form a wedge hedge with the closure direction ({ixator 5) the same angle p and also deflect in the direction of movement P. The lateral walls of the stops of the sliders 18, 19 and 25, 26, facing the wedge clamp 5, tilted and mounted to each other at an angle of 30. Due to this, the locking wedge 5 is always fax 5 -ets in the same open position .. The levers 10 and 11 are rotatably mounted on fixed axles x 30 and 31 and with their outer ends through the bearing NTSh 32 slides are connected to a control 33, which is connected with a horizontal lever 34. On the lever 34, two hooks 35 are hingedly attached to a stylus needle 36, which looks at a punched card (not shown) that is rifled with a punch card 37. The hole in the punched card means that the needle 36 of the igniter and the hooks 35 have moved to the trajectory of movement of the knives 38. The control ha 33 by means of the spring 39 supported on the bearing 40 and the cam 41 returns to its original position. G both sides of the cleaved bearing 32 for both control levers 10 and 11, cams 42 to 45 are installed between the intermediate position of the compression springs 46 and 47 so that the result of reading the punch card is transferred to the wedge connection assembly (latch 5. The horizontal lever interacts with two bearings 48 and 49. The shunting needles 36 (Fig. 9), in the position of the nidiyo pharynx, fix the hole on the punched card, while the hooks 35 lift the horizontal lever 34 from its support 48 as a result, turn the lever 10 so that the wedge lock 5 enters into the drive shaft 6. Following this, the corresponding shaft 1 moves from the lower pharynx position to the upper pharynx position. In the upper pharynx position (Fig. 1O), a hole in the punch card operates, so that the wedge latch 5 opens the connection and by means of the lever 11 is clamped in its locking position. The corresponding hem shaft 1 remains in the upper pharynx. In the position of the upper pharynx (Fig. 11), the Feeder needles 36 do not fix the holes in the punched card. Both hooks 35 are outside the zone of operation of the knife 38, so that the horizontal lever 34 is adjacent to the supports 48 and 49, so that the lever 11 again introduces the wedge-fixer 5 into the drive shaft 6. Then the corresponding heddle 1 moves from the upper mouth to the lower . In the position of the lower pharynx (Fig. 12), both Feeder Needles 36 again do not fix the holes in the punch card, so that everything remains in the previously described position and due to this, the wedge lock 5 is softened by the lever 10 and clamped to its locking position. The corresponding heddle 1 remains at its final working stroke in the lower pharynx. 1 Claims 1.
