Definitions

  • This invention relates to a device adapted to protect needles and threads passed therein during the loading operations of the fabric to be embroidered on the lower beam of embroidering machines.
  • the protecting device which permits to make the loading of the fabric to be embroidered in an easy manner and above all without affecting the correct run of threads going to the needles.
  • Such protecting device is substantially characterized in that it comprises a guard and a rod running parallel to the beam on which the fabric is wound and adapted to provide proper protection to the threads in the needle and spool zones, respectively, said guard and rod being normally maintained in rest position out of the working zone and being brought to the working position during the loading of the fabric by actuation of simple releasing means.
  • FIG. 1 is a schematic side view of the protecting device according to this invention in rest position
  • FIG. 2 is an analogous schematic view of the protecting device in working position.
  • the embroidering machine comprises at least a pair of beams, viz. lower beam 1 and upper beam 2, between which the fabric 3 to be embroidered is stretched out.
  • the embroidery thread 4 unwinds from the spool 5, passes on rollers 6, 7 and 8 to thread in the needles 9 of the needle holding bed 10.
  • the device comprises at least a pair of arms 11, pivoted at 12 on a stationary support or frame. At free ends of the arms 11 is fastened a guard 13, which is adapted to protect the threads in the needle zone as will be seen hereinafter.
  • a pair of arms 14 is pivoted at 15 at an intermediate point of the arms 11 and holds up at its free ends a rod 16. On the same arm 11 is pivoted at 17 a fork 18, adapted to engage on the pin 19, the latter being fixed on said support or frame. On said pin 19 may slide an arcuate slot 20 fast with the arm 11.
  • the arms 11 are released and the guard 13 may be lowered upon the needles 9 as shown by the arrow F2 in FIG. 1. In this position the guard 13 is supported by the metal points 23 on the needle holding bed 10.
  • the rod 16 is in turn spported via the arms 14 and the metal points 24 on the same arms 11. In the position shown in FIG. 2 it is clearly visible how the rod 16 holds the fabric 25 to feed into the machine in a position remote from the spools 5. From the rod 16 the fabric runs subsequently onto the guard 13 and from this to the lower beam 1 for the winding operation without coming in contact with the threads 4 and the needles 9.
  • a device for guarding the needles and threads of said machine during the loading of fabric to be embroidered on said supply beam comprising at least a pair of first arms pivotably mounted about one of their ends on said frame, a guard member carried by the other ends of said first arms, at least a pair of supplemental arms each pivotably mounted about one of its ends on a corresponding first arm between the ends of said first arm, an operating rod carried by the other ends of said supplemental arms and extending parallel to said beam, all of said arms being pivotable from an inoperative position in which said guard and said rod are spaced from said machine to a fabric loading operative position in which said guard is disposed between the needles and the fabric being loaded, and in which said guard and said rod each support said fabric.
  • the device of claim 1 further comprising means to lock said first arms in said inoperative position.
  • said locking means comprises a pin fixed with respect to said frame and a catch member pivotably mounted on at least one of said first arms and adapted to engage said pin in said inoperative position.
  • the device of claim 3 further comprising means on at least one of said supplemental arms to release said locking means as said supplemental arms are moved into said operative position.
  • the device of claim 4 wherein said release means 8.
