Definitions

  • Each disc 26 comprises a cylindrical metal block into the upper face of which (FIG. 2) are machined twelve radial channels 27 to receive the 12 selector members 22.
  • An annular slot 28 is also machined into the upper surface of each disc 26 and each selector member is mounted for pivotal movement on a disc by a pin 29 located in a hole extending through the selector member, the pin projecting at both sides of the selector member and the projecting ends, constituting spigots, being located in the apertures in the walls of the associated channel 27 which are formed by the slot 28.
  • the axis of pivotal movement of each selector member lies in a plane perpendicular to the axle 25. pendicular to the axle 25.
  • each blade 33 then moves over the land 54 between the portion 50 and the slot 48 in the cam plate 37 and thus approaches the blade 39 constituting the control member.
  • the blade 39 is in its raised position, the electromagnet 46 remaining unenergised, and the blade 33 moves be-' neath the end portion 45 of the blade 39 without contacting it-and continues its rotational movement above the cam plate 37. That is the blade 33 in this case remains in its upwardly inclined position.
  • the blade 39 is in its'depressed position, having been pulled down by energisation of th electromagnet 46. The blade 33 thus impinges upon the wedge-shaped end portion 45 of the blade Y39 and is moved downwardly thereby throughthe slot 48 in the cam plate 37 illustrated in FIG. 6.
  • FIG. 7(a) the blade 39 is in its raised position, the electromagnet 46 remaining unenergised, and the blade 33 moves be-' neath the end portion 45 of the blade 39 without contacting it-and continues its rotational movement above the cam plate 37. That is the blade 33 in this case remains in
  • each of the 96 selector members 22 will be presented to a patterning butt of one of 96 jacks in the needle cylinder and will, according to its position, push the jack into its trick or leave it untouched.
  • the stack of discs will programme the next 96 jacks and so on around the needle cylinder.
