Abstract: 11,644. Donner, H. May 18. Parallel knitting- machines.- Relates to a device for taking up freshlycommenced portions of work consisting of either plain circular or flat ribbed fabric knitted in continuous lengths on parallel machines. In forming a continuous band of stocking lengths, Fig. 2, it is necessary, when forming the broad part B, to suspend in the new loops a weighted hook &c. C to give the necessary tension. This is done automatically by bringing into the loops a finger 1, Fig. 4, carried by a cranked lever 2 pivoted to another lever 3, which is in turn pivoted to a slide 5. A stop 11, Fig. 3, carried by a bar 6, normally presses against the side of the lever 3, holding the finger 1 out of action as in Fig. 4, but, when the lever 3 is released from this stop, a spring 15 pulls it over into the position shown in Fig. 5, when the lever 2 is held against a stop 14 by a spring 12 and the finger 1 is held in the new loops D. The slide 5 rests on another weighted slide 8, Fig. 3, to which is pivoted the bar 6, carrying the stop 11 and provided with an arm engaging with a catch 7. When the lever 6 is rocked to the left, Fig. 3, against the action of the spring 10, by means of the catch 7, the lever 3 is released from the stop 11, allowing the finger 1 to come into action. The bar 6 is next released from the catch 7 allowing the slide 8 to fall, and leaving the slide 5 suspended in the new loops by means of the finger 1. The catch 7 is attached to a bar 24, Fig. 18, on which are mounted levers 22, 23 connected by a spring coupling 26 to form a bellcrank lever. An arm 20 carrying a bar 21 is rocked by suitable means so as to rock the arms 22, 23, bringing the latter into a recess T in a bar X, and causing it to lie in the path of a projection 27 on the carriage S. The carriage, moving to the right, carries it up the inclined surface 28, also pushing the bar 24 to the right and bringing a broader part of the catch 7 against the bar 6, thus rocking the latter and so freeing the lever 3, Fig. 4, from the stop 11. The bar 24 is also provided with a plate having inclined edges 30, 31, Fig. 14, engaging with a spring bolt 29, which serves to return the bar 24 after the arm 23, Fig. 18, has ridden up the incline 28 and can come over the stop 27. As the carriage S returns, the stop 27 again engages with the arm 23, moving the bar 24 to the left and completely withdrawing the catch 7 from the lever 6 and thus allowing the slide 8 to fall. The arm 23 rides up the incline 32 and is again pushed back over the projection 27 by the spring bolt 29. By this time the lever 20 has been released, allowing the bar 21 and arm 22 to drop and so bringing the arm 23 out of the path of the projection 27. When a sufficient length has been knitted, the cam 33, Fig. 3, is operated, forcing up the slide 8 by means of a lever 17 and causing a stop 33<1>, Fig. 9, on the bar 6 to engage with a curved lever which is thus rocked, and, by means of a pin 36 engaging with a slot 37 in the lever 3, rocks the latter and withdraws the finger 1. As the bar 6 continues to rise, the stop 11 engages with the side 38 of the lever 3, securely holding it. The slide 5 is kept steady during the withdrawal of the finger 1 by means of a pawl 39 forced into engagement with a rack by means of a spring 40 acting upon a pin 41 attached to the pawl. As the slide 8 rises, a finger 43, Figs. 4 and 5, lifts the pin 41, releasing the pawl 39, the slides 8, 5 being further raised until the lever 6, Fig. 3, again engages with the catch 7, bringing the various parts to their original positions.
