Definitions

  • the object of the invention is to provide a feed means which can be simply adjusted to enable feed rate of the yarn to be altered precisely.
  • a yarn feed means comprises a feed device consisting of a pair of disc like elements each having an interrupted conical face whereby the elements can be moved into a position such that one interrupted conical face interengages the other interrupted conical face, there being on one element a screw means arranged to pass into a conical recess in a mounting shaft for the device, and spring means between said elements arranged, in use, to tend to hold the elements apart.
  • FIG. 1 is a part sectional side elevation of a yarn feed means mounted upon a carrying shaft
  • FIG. 2 is a frontal elevation of one of the yarn feed elements and showing a yarn in one position thereon.
  • a yarn feed element comprises two yarn feed elements 10, 11 each of which is of a form such that one face is in the form of an interrupted cone, there being therefore segments 12 lying on the face of a cone separated by spaces 13 equal in size to the segments 12.
  • Each element has a central boss 14 through which can pass a mounting shaft 15.
  • One of the elements in this case element 11, has, in addition, a boss 16 on its non-conical face and through this boss are drilled two radial holes 17 and 18.
  • the hole 18 is screw threaded to receive screw 19 provided with a conical end 20 and the hole 17 serves to receive a dowel pin 21.
  • the shaft is provided with a conical recess 22 into which the end of the screw 19 can enter (The recess 22 is preferably of an identical cone angle to that of the conical end 20 of the screw 19).
  • the shaft 15 is provided with a keyway 23 into which the dowel pin 21 can pass.
  • a spring 24 which tends normally to hold the elements 10, ll apart.
  • the shaft 15 is provided with spaced peripheral grooves into which seat a pair of snap rings 25.
  • the snap rings 25 serve as stops against which, in their most separated position, the elements 10, II will abut. In the arrangement being described the element 10 will always abut a snap ring 25.
  • a yarn to be fed is indicated by the reference numeral 26.
  • the screw 19 is screwed down to cause its conical end 20 to ride down the face of the recess 22 in the shaft 15 thereby to cause the element 11 to move towards the element 10 to cause maximum intercngagement between the interrupted conical faces of the elements thus the yarn 26 moves around the feed device at a maximum radius from the centre of the elements.
  • the spring 24 is compressed.
  • a feed means such as that described above can conveniently be used for the feeding of a weft thread or catch thread to a narrow fabrics needle loom, which latter yarn will be used to lock the chain stitch selvedge produced by the selvedge knitting needle.
  • a yarn feed means comprising a rotatable mounting shaft, said shaft having a conical recess in its periphery, a pair of disc like elements mounted on said shaft for rotation therewith, each of said elements having an interrupted conical face whereby the elements can be moved into a position such that one interrupted conical face interengages the other interrupted conical face, a screw means on one element and arranged to pass into said conical recess in said mounting shaft, and spring means between said elements and biasing said elements apart.
  • a yarn feed means as claimed in claim 1 in which the conical faces of the feed elements are each provided with alternating segmental portions and spaces.
  • a yarn feed means as claimed in claim 1 in which said shaft has an axially extending keyway on its periphery, one feed element is provided with a boss on its non-conical face, there being a radial screwed hole in said boss to receive a conical ended screw, a second radial hole in said boss, and a dowel pin extending through said second hole and into said keyway in the mounting shaft.
