Definitions

  • ABSTRACT Apparatus for use with a textile machine or the like having periodically reciprocating parts includes actuating means continuously operable with the textile machine.
  • Linkage means operatively connected to the actuating means has a first position operable to impart to the actuating means a reciprocating motion to reciprocate the reciprocating parts and a second position operable to cause the actuating means to terminate the reciprocating motion of the reciprocal parts.
  • the present invention relates to a textile machine with periodically reciprocating parts and more particularly to a hosiery knitting machine and the knitting needles used therewith.
  • the reciprocating parts are operatively associated with non-detachable connecting elements, more particularly links which are so arranged that the continuously operated means which drives the periodically reciprocal parts is guided during its off or disconnect position into an operational mode different from that which occurs during the on or connect position. In this manner.
  • the parts which are to be reciprocated periodically at a high speed, and whose movement path is to proceed linearly or curved, can be connected and disconnected in rapid sequence, whereby the movement energy is deflected but not nullified, when the reciprocal movement of the reciprocating working or operating elements, such as knitting needles or the like, is terminated, the stroke or movement of the continuouly operable drive means, though it continues, is guided through a stroke displacement into another, e.g. an opposite, direction.
  • the deflection of the stroke direction may be provided by one or several non-detachable connecting elements which are connected with control members which restrain or release the movement of the connecting elements.
  • the control members may consist, for example, of couplings or brakes which actuate the connecting elements. In some cases, certain control members may introduce unavoidable play of these members which may lead to inaccurate movements of the connecting elements. In order to avoid this, the control members may be attached also in a non-detachable relationship, to the connecting elements. Furthermore, the control members may be arranged so that in order to restrain movement or terminate reciprocation they can be transfered into a dead center position.
  • the non-detachable connecting elements comprise two spaced bars each having one end pivotally mounted on its own fixed pivot in the same plane, and which are inter-connected by means of two bar sections which form a knee joint.
  • the knee joint receives a continuous and constant stroke movement and each bar is provided with a hinged pair of levers in the form of control members that are connected in hinged relation on one hand, with said bar and. on the other hand, with the end of a common shifting lever.
  • the ends of the shifting lever may be provided with stop members for the hinged pair of levers in order to support the pair of hinged levers during shifting to the dead center position. It is also advantageous to provide the hinged pair of levers with stop contours which secure the on-and off postion. These stop contours can be affixed either on both bars spaced from each other, or they may be situated in form of independent stop points, in a gear housing which accomodates all elements, such as the bars control members, hinged lever pairs and connecting elements.
  • the constant stroke movement delivered to the fulcrum of the sections which form a knee joint can be produced either by a cam gear, a linkage, or by a gear.
  • FIG. 1 is a schematic view of apparatus providing for periodic reciprocation of elements according to one embodiment of the invention.
  • FIG. 2 is a schematic view of another embodiment employing a lever linkage in place of the knee joint included in the FIG. 1 embodiment.
  • FIG. 3 is a schematic view of another embodiment utilizing pairs of hinged levers as control members.
  • FIG. 1 shows a slide 3 which is to be reciprocated in the direction indicated by the double arrow 1, along the length of stroke indicated by the double arrow 2,
  • the slide 3 operates in conjunction with a slide needle (not shown) of a hosiery knitting machine or the like.
  • a hub element is reciprocated between the two positions indicated by the double arrow 4 by known means including linkages,
  • a shifting lever 9 is pivotally mounted at a central location and has pivotally connected at one end an arrestingpin 10 which is adapted to engage or disengage from a slide element 12.
  • the slide element 11, is free to reciprocate in the direction indicated by the double arrow 14 when the arresting pin 10 is disengaged from the slide element 11.
  • the arresting pin 10 engages slide element 11 the latter is prevented from being reciprocated.
  • Another arresting pin 13 is pivotally connected to the other end of the shifting lever 9 and is adapted to engage or disengage a slide element 12 which operates the slide 3.
  • the slide element 12 is free to reciprocate in the direction indicated by the double arrow 1 when the arresting pin 13 is disengaged from the slide element 12. However, when the arresting pin 13 engages the slide element 12, the latter is prevented from being reciprocated.
  • FIG. 2 a constant stroke reciprocal movement is imparted to a bar 34 in the direction indicated by the double arrow 33.
  • a lever 35 has a central portion pivotally secured to the bar 34.
  • a shifting bar 38 has a fork 41 at one end adapted to engage the end of lever 35 and another fork 40 at the other end adapted to engage the other end of the lever 35.
  • a slide element is pivotally connected to one end portion of the bar 35 and carries a slide element reciprocal in the direction indicated by the double arrow 1 to thereby reciprocate the slider 3.
  • FIG. 3 shows a further alternate embodiment wherein a slide 3 is reciprocal in the direction indicated by the double arrow 1.
  • a knee joint 25 pivotally connects bars 22, 23, 24. Reciprocation of a hub element between the positions indicated by the double arrow 4 will articulate the bars 22, 23, 24 to various positions including the position indicated by the broken lines 22, 23', 24, 25'.
  • a bar 27 has one end pivotally connected to bar 23 I and the other end pivotally connected to a fixed pivot central portion pivotally mounted on a fixed pivot and one end operably connected to the bar 27 through intermediate control links 15, 16.
  • the shifting lever has its other end operably connected to the bar 28 by means of control links 17, 18.
  • the pivot 21, on the end of the bar 24 may be free to reciprocate or its reciprocation may be terminated by disposing the pivotal control links 17, 18 in a manner similar to the pivotal control links l5, 16.
  • the lower section of shifting lever 26 has a stop member 30 similar to stop member 29 and that a fixed stop member 32 is provided similar to stop member 31.
  • the shifting lever 26 and pivotal control links 17, 18 have a dead center position 19 similar to the previously described dead center position 19. It will be seen that with the shifting lever 26 in the solid position in FIG. 3, the pivot 21 at the end of bar 24 will not be able to reciprocate. However, when the position of the shifting lever 26 is changed to that generally indicated by the broken lines 26, the pivot 21 at the end of bar 24 will be free to reciprocate in the direction indicated by the arrow 14.
