Abstract
762,050. Shuttleless looms. SULTZER FRERES SOC. ANON. Sept. 13, 1954 [Sept. 19, 1953], No. 26403/54. Class 142 (2). Weft patterning mechanism for a gripper shuttle loom comprises weft feeders 83, Fig. 5, carried by a feeder changer 81 which can be turned about its pivot by cam links 46a, Fig. 6, on a pattern chain 46 ; the selected feeder is located (for sliding endwise to present its weft to a shuttle) by a notched sector 84, Fig. 5, and a cam-operated lever 87. The pattern chain sprocket 45 is driven through a Geneva mechanism, the pin wheel of which may have less than its full complement of pins so that the pattern chain is not advanced on every pick of the loom; there may be two Geneva mechanisms in series to increase the scope of variability in the drive. A clutch (not shown) as interposed in the shaft 49 between the follower lever 48 and the feeder changer 81, the clutch having a single V-shaped dog so that if the loom is turned backwards, without moving the pattern chain, the dog rides out of the notch in the other clutch element and re-engages, under spring load, when the loom runs forward again. Fig. 10 shows a simpler mechanism controlling two weft feeders 131, with no pattern mechanism other than a cam 134 which imparts a greater movement to a rod 142 than is necessary to bring the feeder changer 128 against stops 156, 157, the surplus movement being absorbed by springs 154, 155.
