  • One arm of the lever 64 is integral with the hub 65 and has pivotally connected theretoat II a link 12 in turn connected to a lever 13, by passing through a bushing 14 I carried by said lever, being retained in said bushing by a screw 15.
  • the lever 13 is pivoted intermediate its ends to the machine frame at 16 and one arm thereof has a toe ll normally held in engagement with a drum 18 or cam 18 mounted thereon by the tension of a coil spring 19 connected at one end to the other arm of a lever 13 and at its other end to a pin or screw 80 carried by a plate or bracket 8
  • the other arm 83 of the lever 64 which is a right angled continuation of shaft 66, projects in the direction of the pattern chain l5 and normally seated thereupon is a pin 84 connected to and laterally extending from a block or plate 85 fastened to the starting pawl 38 by screws 86.

  • the idler 35 carried by the pawl 20 is in engagement with a lug 93 carried by a link of the pattern chain I5 which lug holds the pawl 28 elevated and prevents the same from engaging the teeth I9 and advancing ratchet l8 although the pawl 20 is constantly reciprocated once every two courses throughout the knitting of the stocking.
  • the two pawls 20 and 38 act .as one during theknitting of the bottom half or narrowing of the toe to advance the pattern chain once for every two courses of knitting throughout the knitting of the toe.
  • I are rendered ac- A spring 96 attached at one end to the pin or screw 58 and at its other end to a pin or screw 9'! together with the pin and slot connections between the lever 59 and the link 55, compensate for inequalities in the heights of the lugs 95".
  • the spring 96 is much stronger than the spring contained within the pick block 8 and consequently when the toe 03 of the lever 59 is raised by a lug 95" the pins the upper portions of their respective slots 55, 51 notwithstanding the fact that the lever 50 at the same time, raises the butterfly cam I9 against the tension ofthe spring contained within the pick block 8. If a lug 95" is higher thannecessary -to elevate the widening picks to operative position the extra height'is taken up by the spring 96.
  • the relative arrangement, spacing and numlocation of the said links and recesses H00 causes her of special links 95.98.99 in a pattern chain depends upon :the form of toe desired, the chain I5, Fig. 11, effecting the knitting of the elongated toe disclosed in Fig. 12 while the arrangement of links 95, 99, 99 on the pattern chain it, Fig. 13, results in the somewhat shorter or less pointed toe shown in Fig. 12.

  • the cam 18 may be of any length desired it must be of suflicient length to permit the starting pawl 38 to advance the ratchet wheel l8 and the chain l5 through a distance represented by three teeth l9 by which time the pawl 20 is clear of the pattern chain lug 93 and is in position to advance the ratchet wheel l8 and chain l5.
  • one or more plain links H2 permit pawl 20 to retime the pawl mechanism and chain l5, by continuing to advance the ratchet wheel l8 until the chain lug 93 again engages the idler 35 to idle the pawl 20.
  • the arrangement of links shown in- Fig. 11 eilects the knitting of the stocking toe H3 of the stocking I ll shown in Fig. 10.

  • the widening picks I, l are specially controlled to effect the knitting of the stocking toes shown in Figs. l0, 12, 14. 15, the narrowing picks 6, 6 may be specially controlled or both the narrowing and widening picks may be specially controlled. Furthermore, the picks may acts upon jacks or other butts instead of on the butts of needles to effect the desired results.
