Definitions

  • the invention relates to means for providing enlarged needle wale loops along the inner selvages of heel tabs of full-fashioned hosiery, to facilitate the impalement of'said loops on the needles for the formation of the foot.
  • Figure l is an end view of a needle bar of a full fashioned machine, with a needle mounted thereon, representative of the needle row and with my improvement in place.
  • Fig. 1a is a sectional view on line la of Fig. 3 and showing the loop enlarging point in dotted lines in idle position.
  • Fig. 1b is a view of a detail.
  • Fig. 2 is an elevation of the needle bar, with my improvement in place as viewed from the front of the machine.
  • Fig. 3 is a plan view of the 'ieedle bar with my improvement in place.
  • Fig. 5 is a detail view of a bracket member for supporting the loop enlarging finger on the pivot shaft therefor.
  • Fig. 6 is a view of the bracket member of Fig. 5.
  • Fig. 7 is an enlarged view of a part of a spring needle of special construction, together with the loop enlarging point in position to cooperate with the needle in-the enlargement of the loops.
  • l indicates the needle bar of a full fashioned knitting machine.
  • a needle is shown at 2, this being one of the straight row of needles carried by the needle bar as in ordiof the point of the beard and also below the level of the usual eye or recess 21) on the beard side of the needle.
  • a loop enlarging finger 3 is adapted to cooperate with each of these special needles, it having a curved end 3a terminating in a point 31) which when the finger is set in position to enlarge the loop enters the special eye 2a in the back or beardless side of the needle.
  • This loop spreading member has a vertically extending portion 3d to lie close at the back of the needle, when in op crating position, to add its thickness to that of the needle stem for obtaining the enlargement of the loop formed on this needle.
  • the finger has Fig.
  • each end of the section of instep needles may be shifted by taking them out and replacing them in another location. This will necessitate filling the spaces left by the removal and shifting of these special needles with ordinary needles.
  • the special and ordinary needles may be interchanged in position to get various widths of instep fabric, as may be desired.
  • the needle bar may be practically of one piece from end to end, and yet the length of the instep row of needles may be altered at will. This can be accomplished by ad- 35 justing the enlarging fingers along the rod 5 which forms their pivotal support.
  • the said fingers may be held in any position to which they may be adjusted by friction or by any other suitable means.
  • loop enlarging fingers renders it unnecessary to use a needle bar in sections capable of adjustment or replacements for get.- ting different lengths .of the section of the needle row for making the instep.
  • the needles are maintained in their upright positions. No deflection of the needles take place when the loop enlarging fingers are set in operative position.
  • the loop enlarging fingers provide loop engaging 5g portionswhich are of rigid construction.
  • the setting of the loop enlarging fingers is preferably done by turning the shaft or rod upon which they are mounted. This can be accomplished either by hand or automatically.
  • the I setting of the fingers into their operative or idle positions is performed when the needles are in their lowest position.
  • the machine as usual in full-fashioned machines includes sinkers and knock over bits.
  • the sinkers overlie the stitch which is being enlarged by the upthrust of the fingers.
  • the action of the knitting element; spring beard needles and sinkers and knock over bits is the same relative to each other as in ordinary full-fashioned knitting practice.
  • the upper end of the enlarging finger presents a surface sloping towards its point of engagement with the needle so that'in penetrating the opening in the stitch the enlarging action will be that of a wedge acting gradually n the yarn.
  • a pivotal support 5 may consist of a shaft or rod turnable in bearings 6 on the needle bar.
  • This shaft is under tension of a spring lcoiled about it and tending to rotate theshaft in a direction to position the loop enlarging point adjacent or virtually against the needle stem.
  • the shaft has a finger piece 8 fixed thereto at its right hand end which may be used in turning the shaft to make the loop enlarging points assume their idle positions'as shown in dotted lines in Fig. 1a. When in this position the points will be retained by a catch lever- 9 having a notch l0 receivinga projection H on the finger piece. This catch may be under control of a spring pressing it against a stop l2 Fig. 1.
  • the catch lever is pivoted at 13 and has a downwardly extending arm 14 by which said catch may be operated.
  • the spring When operated to release the shaft 5 carrying the loop enlarging fingers, by withdrawing its notched portion ID from the finger piece, the spring will turn the shaft and the loop enlarging fingers thereby will be positioned at the needles to cooperate therewith in enlarging the loops.
  • the loop enlarging finger will be adjacent,the needle stem but need not contact therewith,-though the point of the loop enlarging finger will be buried in the special eye in the back of the needle.
  • the loop enlarging points are desirably carried by base plate portions It: held adjustably by screws I6 passing through slots in said base plates into the platelike bracket members 4 which are brazed to the shaft 5.
  • the adjustment of the loop enlarging members allowed by the screw and slot arrangement along the shaft may be as desired, say A" or more.
  • the catch lever 9 may be controlled automati-' cally by a connection engaging the arm l4 thereof, sa d connection being operated automatically from the control cam shaft at the rear of the knitting machine, such, for instance, as shown at b in Letters Patent of the United States No. 1,982,991, December l, 1934, though as above indicated, the invention is not limited in this respect and setting of the loop enlarging points may be effected by hand.
  • the loop enlarging finger is limited in its movement towards the needle by the plate 4 contacting the upper surface of the needle bar.
  • the finger 3 when in position for operation does not contact with the needle, nor does the point 3b strike the bottom of the eye, butis limited to a position intermediate the depth of the eye.
  • back as applied to the needle refers to that side or edge which is opposite to that side upon which the spring beard is located, this being so notwithstanding the fact that when the needle is mounted in a fiat full-fashioned knitting machine, this side or edge which we now refer to as back faces towards the front of the machine.
  • a row of needles carried thereby including those located at the points in the needle row where the wales adjacent the inner selvages of the heel tabs are knit and which have an eye in the back surface thereof, and fingers movably mounted on the needle bar to be adjusted to and from the needles having said eyes, said fingers having points to enter the eyes of said needles, the loops formed by said needles being enlarged by the combined thickness of the fingers and the needles adjacent which they lie, substantially as described.
  • a needle bar of a full fashioned knitting machine having a row of needles and fingers pivotally mounted on the needle bar and thereby swingable into a position adjacent the stems of those needles which form the loops.
  • loop enlarging fingers mounted thereon, adjustable to and from the needle row and adjustable on the bar to different positions along the needle row, said fingers when in position adjacent certain of the needles enlarging the loops along the inner selvages of the heel tabs, the adjustment of said fingers along the needle row enabling the length of the instep section of the needle row to be varied, substantially as described.
  • loop enlarging fingers adjustable to operative position adjacent certain needles and to an idle position relatively remote from the needles, a rodmounted on the needle bar forming a pivot for the said fingers, said fingers being adjustable lengthwise of said rod to coact with the desired needles for varying the length of the instep section of the needle row, substantially as described.
  • loop enlarging fingers adjustable to either idle or active position relative to the needleswhich form the loops along the inner selvages of the heel tabs, and adjustable along the needle row to accord with different lengths of the series of needles which form the instep.
  • I 7 In combination with needles, sinkers and knock over bits of a full fashioned knitting machine, fingers adjustable from idle position to active position at the needles, said fingers pointing in the same direction as the needle penetrating the loops on the beardless side of the needles to enlarge the same, while held by the sinkers against the thrust of the advancing needles, by
  • a spring beard needle having a recess in its back edge and a loop'enlarging member carried by the needle bar and having a point to enter said re- 10 cess, substantially as described.
