of the feed setting cam 18 therefore the tramsmission rod 60 gives no influence to the feed adjuster 41 on the other hand the follower pin 31 of the changeover arm 30 comes to engage the cam face 172 of larger diameter of the feed changeover cam 17 the changeover arm 30 is therefore turned in the counterclockwise direction and displaces the pivot 32 to the lowered position as indicated by the broken line in fig3 the follower 36 is therefore brought into engagement with one of the feed control cams 8 1 8 2 for controlling the feed adjuster 41 through the transmission rod 34 and the vertical rod 44 simultaneously one of the pattern cams 7 is selected by the pattern selecting cam 13 and the transmission rod 23 with the end follower 23a which is operated in association with the pattern selecting cam 13 thus a pattern is produced which is accompanied by a varied feed control as shown in the groups of patterns 81 1 82 1 83 1 and 81 1a 82 1a 83 1a shown in fig2 when the operating dial 90 is turned to the position as shown in fig2 in which the arrow mark 91 points the indexing mark s 2 on the pattern indication panel 80 the u shape member 93 is held through the connecting rod 92 in the angular position indicated by the solid line s 2 in fig3 in this set position of the u shape.
