Definitions

  • This invent on relates to circular, independent needle, knitting machines of the dial and cylinder type; and, particularly, to stop motions for preventing needle damage and yarn load-ups in such machines.
  • the primary object of the invention is to pro vide a stop motion system which will be absolutely reliable, but less expensive and less complicated than those of the prior art.
  • a further object is to insure that the stop motion system will provide for a safe failure; i. e., will render the knitting machine inoperative if there is any electrical failure in the stop motion system,
  • a stop motion system which includes: a single mechanical trigger for protecting both the dial and the cylinder needles, mechanical means for Withdrawing the trigger from the vicinity of the needles to render it inoperative when it might interfere with their operation, an electrical switch actuated by the trigger and controlling current to a solenoid which actuates the belt shipper or other means for stopping the rotation of the dial and cylinder.
  • Figure l is a diagrammatic view of a stop motion system after the manner of the invention, showing the mechanical trigger in its locked position; i. e., permitting the machine to operate;
  • Figure 2 is a plan View from below of the mounting for the mechanical trigger of Figure 1;
  • Figure 3 is a plan view of the mounting and trigger of Figure 1, with the trigger in unlocked or released position, i. e. causing the machine to stop;
  • Figure 4 is a diagrammatic side view of the mounting and trigger of the other figures, showing the location of the trigger with respect to dial and cylinder needles when in the locked position of Figure 1.
  • this stop motion system includes a mechanical trigger I supported upon a retractable mounting 2 and actuating an elecas shown in Figure 4.
  • the cylinder needles are raised high enough to hit against the trigger in its normal operating position, e. g. during reciprocatory knitting of the heel and toe. At such times, it is necessary to withdraw the trigger I without, at the same time, releasing the actuator l3 of the switch 3. This is accomplished by making the trigger mounting 2 retractable so that the entire assembly can be withdrawn away from the needles to the position designated by the dotted lines in Figs. 1 and 2.
  • aesasgv mounting 2 is slidably held on a bracket IT by means of a slot l8 and guiding screws l9 and 20.
  • the bracket I l is mounted upon the pivoted carrier ring (not shown) which supports the entire dial unit (also not shown) in conventional manner. This method of supporting the trigger assemblyypfi mitsiit and its associated retracting mechanism to be withdrawn from ,the ;cylinder area for purposes of repair, independent operation of the cylinder, etc.
  • a red 22 connected to thapattermdrumlnot shown in Fig. 2, and thereby removes the entire assembly, including the triggery'from proximity to the needles when desired withoutbreaking;
  • a stop motion system which includes a mechanical trigger disposed in arplane extending from approximately theintersectiori; of therl'ongitudinal axes of said dial and cylinder needles, a mounting for said trigger retractable in said plane in a direction away from said needles, said trigger being automatically retractable upon said mounting when struchby said needles or yarn carried by them, aasolenoidgadaptedto operate said means for stopping said; machine, and means for providing anzel'ectricalz current to said solenoid including a switch actuated by said trigger.
  • a stop' motion system according to claim 1 and'jwherei'n said'electric current is at ,nortime during xtheoperation of said systemgrounded to said machine.
