Abstract

934,064. Stop-motion for delivery rollers. TWEEDLES & SMALLEY Ltd. Nov. 20, 1961 [Nov. 22, 1960], No. 40163/60. Class 120 (2). In a drilling &c. frame having delivery rollers 16, 17, the upper of which is carried by an arm 17 pivotally mounted at 18 behind the rollers, means are provided for interrupting the delivery of yarn comprising a yarn-feeler 21 pivoted to the forward end of the arm, which, when a yarn breaks, moves so as to be engaged by a driven member and be thereby raised to move the arm about its pivot and lift the upper roller away from the lower roller. The driven member is a reciprocating lever 26 fastened to a shaft 14 which is constantly rocked by a pivoted bellcrank 22, 23 worked by an eccentric 24. When the feeler falls an abutment 27 thereon engages the lever so that when the latter makes its next upward stroke, the arm is lifted to position A where roller 16 is clear of roller 15 in which position it is retained by an abutment 28 engaging a catch 29. A further abutment 30 serves to retain the arm in position B. The roller 15 is driven; shafts 14 and 18 run through the length of the machine; the arm 17 is mounted between bosses 20 on the shaft 18; and the yarn is guided over the path shown by guides 12, 13 and by passing under the shaft 14.
