The feeling-bars, which are thus relieved of any appreciable bending strain, can therefore be made of thin wire and be arranged very close together, since there are no horizontal auxiliary needles or eyes.

The projections m of the feeling-bars can be arranged at difierent heights, as will be seen from Fig. 3, so that the needles can be arranged one over another in several rows to enable a row of feeling-bars to be distributed among several rows of needles.

Ajacquard-machine provided with such apparatus operates in the following manner:

Before the spring-casing b and a griffep, both of which parts are operated by known transmission mechanism, have completed their movements thefeeling-bars are lowered by the downward movement of the barg or the frame h. The feeling-bars that pass through the holes in the card can then enter the card-cylinder and so completely descend, while the feeling-bars that strike against the solid portions of the card remain at a certain height, at which their heads n then hold the corresponding needles, Fig. 2. When the feeling-bars have been set, the spring-casing b is moved toward the lifting wires or hooks q, so as to move all the free needles by means of the springs 0 in the direction indicated by the arrow in Fig. 2 and to bring their lifting wires or hooks q into the paths of the blades in the grifie while the lifting Wires or hooks corresponding to the stopped needles remain in their original positions. The griffe after having been raised falls, and at the same time the spring-casing b moves backward in the direction indicated by the arrow in Fig. 1, so as to draw back the needles. Shortly before the spring-casing b commences to return the bar g or the frame h lifts all the feeling-bars, so as to enable the card to move forward by a row of holes. The operation is then repeated in the manner hereinbefore described.

Instead of round feeling-bars flat bars f, Fig. 5, can be used, the lower ends of which are provided with points f which on meeting holes. in the card can pass through them. These bars are in a manner similar to that of the arrangement hereinbefore described, provided with lateral projections m and thickened portions or heads 11, which release the needles 0, when the bars f are in one end position, but stop the needles when they are in the other end position, Fig. 5. The thickened portions or heads n can be mounted loosely on the projections m, since they are prevented from falling out by the two walls 0 and d.

The bars f are provided with slots 2, throughfeach of whichjthere passes a rod h, which is provided with thickened portions b and by means of which the depressed bars are lifted when their points f have to be raised out of the holes in the card 1c.

3, as shown,or in any other suitable manner.

In order to enable the ends of the feelingbarsf or the points f to be accurately introduced into the holes in the card, the round or fiat bars can be pressed down by springs.

In the arrangement shown in Fig. 5 springs 4 can act on projections 5 of the bars f, as shown.

Instead of springs movable magnets can be used, which on moving draw the feeling-bars for f with them.

In the arrangement shown in Fig. 7 the bars f are connected by cross-pieces with the armature 6 of an electromagnet (not shown in the drawings) which at a given time moves the armature, with its attached bars f, in guides 7. The points f are in this case made of non-magnetic materialfor example,brass. The bars themselves may, however, be magnetized and attracted by a stationary armature. l
