Definitions

  • This invention relates to a thread guide drive
  • the object of the invention is to overcome these objections. This is attained by employing cylindrical rollers or guide blocks engaging in the continuous cam groove for transmitting movement between the cam discs and loading frames, these rollers or blocks being connected with the holder of the loading frame by a simple hinge 35 joint.
  • This simple hinge joint ensures aperfect guiding of the guide block in the cam groove in the case of slight changesof pitch owing to the necessary play for fitting.
  • guide blocks it is advisable when employing guide blocks to connecty this with the holder of the loading frame by a cross-joint so that it can adapt itself to any change of pitch.
  • the invention presents the advantage that transmission means can be employed between the cam and loading frame, which means ensure at least a line contact and when guide blocks are employed even a surface contact without rimpeding the adjustment of the cam disc. construction wear at this point is almost completely eliminated so that the former interruptions in working no longer occur and consequently the machines can be run economically. Moreover, expense by replacement of these elements is 55 eliminated as they last indelinitely.
  • FIG. 1 shows the'employment of a guide block in elevation.
  • Fig. 2 is a section on line A-B of Fig. 1.
  • Fig. 3 is a similar View to Fig. 1 of a modiiied form of construction.
  • Fig. 4 is a section on line C-D of Fig.3.
  • Fig. 5 shows the employment of a cylindrical 10 I roller.
  • Fig. 6 is a section on line E-F of Fig. 5.
  • the swinging takes place over bevels 8 of the 20 Asquare 4 so that theguide block can adapt itself to the actual position' of the cam disc.
  • Figs. 3 and 4 show the same arrangement only in this instance the guide block 3 is connected with the holder of the loading frame by a crossjoint in such a manner that itcan adapt itself to any alteration in the pitch of the cam disc.
  • the square 4 is loosely mounted on a bolt 9 fixed on the holder 5. and carrying the loosely mounted guide block on-laterally projecting pins I0.
  • the bolt has a pin I I which engages in a slot in the square limiting the oscillating movement.
  • a cylindrical roller I2 is employed which is mounted on a sleeve I3 which is 40 loosely mounted on a bolt Ii fixed in the square 4.
  • the thread guide drive can evidently be employed everywhere where continuous cscillatable 'tip curves are employed, that is also in spool spinning machines, ring twisting machines, twisting machines and winding machines.
  • a thread guide drive especially for centrifugal spinning machines for artificial silk in which the drive transmission 'to raise and lower 50 the loading frames is effected by cam discs which are cscillatable to vary the stroke, comprising in combination with the loading frame and the cam disc and in which said cam disc has a continuous groove, a holder carrying said frame, a guide element engaging in said groove having a line contact with the Wall of the groove, and a hinge connection between said guide element and said holder constructed and arranged to produce an oscillating movement in one direction and to be guided in its movements in two directions with said guide element maintaining its original contact With the walls of the cam groove irrespective of the tiltable adjustment of the cam disc.
  • the guide element consists of a cylindrical roller.
  • a thread guide drive as speoied in claim l in which the guide element consists of a guide block and the hinge connection consists of a cross-joint.
