1304151 Tufting machine SINGER CO 27 May 1971 [3 Nov 1970] 17393/71 Heading DIG A tufting machine which produces tufts of chosen lengths unrelated to the needle stroke comprises a first looper 26 rockable through a chosen adjustable angle to intercept a loop presented by the needle 22 and a second looper 58 for intercepting the loop pulled down by the first looper, the second looper being adjustable towards and away from the work support 24 to conform to the pile height selected by the adjustment of the first looper. The first looper is carried on a shaft 32 oscillated from a shaft 34 by an eccentric rod 38 adjustably engaging a slot 42 in a pivoted arm 40 connected to the shaft 32 by a link 48. Movement of bolt 44 along slot 42 adjusts the amplitude of swing of the first looper. The second looper 58 is adjustably secured by bolts 64 to a bar 62 pivoted at 84 to the machine frame and oscillated from a rock shaft 74. The looper 58 is moved along face 70 of bar 62 to register with the lowest position of looper 26. A stationary knife 86 is adjustably secured to the frame to co-operate with looper 58 to sever a tuft thereon as that looper swings back from looper 28. Bolt 56 may be loosened to allow looper 26 to be swung clear to allow looper 58 to produce short pile in the conventional manner if required, when bolt 80 may be loosened to allow looper 58 to be be reversed and knife 86 omitted to produce by means not described. positioned nearer needle 22. Looper 58 may uncut pile. The needle stroke may be varied
