You invention relates exclusively to education a Jäustenaeohanismus for chain knitting machines or chains Knitting machines to control the speed of the infeed of the chain ends for the purpose of creating a patterned chain knitting

The master mechanism described in the previous application includes a counter component in the form of a chain, which is around a toothed drum runs and with. previously applied tenons or the like is provided *

To change the pattern of the fabric when making it with in such a machine the arrangement of the pins on the chain is changed * although a number of chains with correspondingly different pin arrangements in one considerably increased effort could be provided, is the usual Practice t the cones on a chain of the pattern mechaaisous νημ » to add. Because such a chain is usually relatively long and wide and has a large number of cone eleaontes has, the implementation of the same is very time consuming.

The invention is based on the object of creating an iSua tenne chanlsrnus with a chain having patterns learning, which can be easily removed and put on

This effectively prevents the pattern elements from being removed from the chain «

In a preferred embodiment, two recesses are formed at each end in each nut element Edge areas of the same, with the recesses eioh in the essentially at right angles to each other extend in such a way that After inserting the pattern element in the desired position, the first recess extends in the longitudinal direction of the chain, while the second recess extends at right angles the chain extends.

The area of the Mustor element delimiting the second recess thus coincides with the reduced area of the journal

There are opposite ends of each cross-peg on the chain preferably designed to be reduced, and the reduced sins extend through complementary openings in the chain links and have narrow annular grooves, which generally U-shaped spring clips can accommodate »so that the links be held in their position as in an ordinary 3oll * nk "tt".

There are three groups 04, G5 «ad vtib WählklijjKea available, each comprising 16" selector pawls in two rows of 8 pieces, corresponding to the 16 pattern element tracks (eight times each) of the respective pattern chain, as can be seen from Figure 3. The horizontal leg 27 & every »el! Pawl 27 is provided on its outer% de with a small roller 28 on which the curve area 9b of a lifting terminal

Between the groups of Wiblklinken (27) are spacer bars SB arranged. On the back of the Kabelhal + «.

A selector pawl automatically returns to this position and gives the corresponding operating rod (23) fret, see above that this returns to the right under the action of a spring (FIG. 2) when it has moved away from an iiuster element (9). The stop B ^ ange (34) ensures that the profile of the fcuster elements (9) either is used entirely for maximum rotary motion to exercise on the dials, or that it is only partially is used.

Body that enables the full profile of the curve area (9 b) of the Kustereleroentes is used. Assuming that the Change gears are chosen so that a "false spot" repetition is generated in eight runs, the following happens:

(e) In two passes, the selector pawl 27 is released from its neutral position Position raised to its highest position on a liuster element.

(ee) Two runs follow, during which the selector pawl remains while the chain continues to turn.

(eee) Then the selector pawl rolls off the during two runs Top of the pattern element and takes its neutral position in contact with the stop rod (34) again.

(ev) Two runs follow to allow the slack yarn to recover before the next cycle begins.

In order to enable all of the selection pawls to lift off the pattern chain ^{and come} free of them, the subframe SJF is arranged above the drum housing H so as to be pivotable. Ee iet a pivot axis (56) is provided, which runs right through the frame SP and is mounted at its ends in bearings (37) (Figure 1) in the housing H.
