Definitions

  • FIG. 1 of the accompanying drawing represents a fragmentary sectional view of a knitting machine constructed according to the invention
  • Fig. 2 is an elevation at right angles to Fig. 1,
  • Figs. 36 are diagrams illustrating the needle positions at difierent stages of the knitting operation
  • Fig. 7 is a fragmentary sectional view of a machine of modified construction
  • Figs. 8-11 are diagrams illustrating the needle movements obtainable with the modified machine construction.
  • the machine comprises a needle cylinder 9 having vertical tricks in which the knitting needles are slidably mounted in the usual manner.
  • the needles are controlled and operated by rocking levers Ill and II which are fulcrumed on pivots I! carried by bearing brackets IS, the latter being mounted on a support H secured to the needle cylinder 9.
  • rocking levers Ill and II which are fulcrumed on pivots I! carried by bearing brackets IS, the latter being mounted on a support H secured to the needle cylinder 9.
  • There is one rockinglever for each needle and the butts of the needles engage in forks at the ends of the levers so that the rocking movement of the levers will result in an up and down movement of the needles.
  • Levers l alternate with levers II, the former being double-armed and the latter singlearmed.
  • a vertically reciprocated operating ring I8 is provided with arms i3 and I secured tothe ring by means of leads M.
  • the arms 13 engage the levers I0 pivotally at one side of the fulcrum l2, and the arms l5 engage the levers l I in the same way but at the opposite side of the fulcrum.
  • the result of this arrangement is that one group of alternately arranged needles will be moved upwards while the other group is moved downwards by the operating ring l8.
  • Figs. 3-6 illustrate the needle movements rela- .tive to the cylinder trick wall 25 of the machine.
  • Six consecutively numbered needles are shown in these figures, (eight needles in Fig. 2), the needles with odd numbers being operated by the levers H and those with even numbers, by the levers Ill.
  • Fig. 3 the needles with odd numbers are descending and the needles with even numbers are being raised by the downwardly moving operating ring i8.
  • all the needles will be on a level with one another, as shown in Fig. 4.
  • the needles with even numbers will be on a higher level than those with odd numbers, as shown in Fig. 5.
  • the needles When the operating ring i8 reaches its lowermost position, the needles will occupy the position shown in Fig. 6 which is reversed from that of Figs. 1
  • Figs. 8-11 illustrate such anaction.
  • the needles With odd numbers are about to descend and will do so while the needles with even numbers remain stationary in their lowermost positions.
  • both sets of needles are level as shown in Fig. 9, the needles with even numbers will be raised, as shown in Fig. 10, while the needles with odd numbers remain stationary, and when the needles with even num bers again arrive in the lowermost position, as shown in Fig. 11, the cycle of operations is repeated.
  • a circular warp knitting machine comprising a needle cylinder, needles carried thereby, the needles being divided into two groups, the needles of one group being intercalated with the needles of the other group, all of said needles being operated simultaneously, but the needles of one group being operated out of phase with the needles of the other group.
