Definitions

  • the invention specified in the claim is therefore based on the object of accommodating both the control curves and the selection device in the region of the center of gravity of the sewing machine, that is to say where there is only a limited space available due to the design.
  • the sewing machine shown in FIG. 1 has an upper arm 1 which is connected to a base 3 via a stand 2.
  • the base 3 is supported by a base plate 4 and is widened towards the front relative to the stand 2 and the upper arm 1. It is equipped with a fabric support arm 5 which is displaced rearward with respect to the central axis of the base 3 and in which the lower stitch-forming tools, in particular the gripper of the sewing machine, are mounted.
  • a main shaft, not shown, mounted in the upper arm 1 of the machine drives a lower shaft 8 via a toothed belt 6 (FIG. 2) and a toothed wheel 7, which shaft serves to drive the gripper in a known manner, not shown.
  • a carrier 9 is fastened with screws 10 in the base 3 of the sewing machine.
  • an axle 11 is fastened in two bearings, on which a block 12 is loosely mounted, which consists of a series of control cams 13 arranged one behind the other and a gear 14 arranged in front of it. This meshes with a gear 15 fastened on the shaft 8.
  • an adjusting crank (not shown) is rotatably mounted, the position of which can be adjusted by means of a transmission linkage (also not shown) of an adjusting disk 16 rotatably mounted on the carrier 9 (FIG. 1) -Direction of a slider 17 determined.
  • a selection device 18 is installed in the carrier 9 (FIG. 2).
  • a number of levers 20 corresponding to the number of control cams 13 is suspended on an axle 19 mounted in the carrier 9.
  • Each lever 20 is equipped with a locking arm 21 and an arm 22 projecting upwards.
  • a feeler lever 25 is rotatably mounted on each lever 20 and has two scanning lugs 26 and 27.
  • the levers 20 can each be locked in two positions by means of a locking rocker 28 which is pivotably mounted in the carrier 9.
  • its locking arms 21 each have a Ra - TNase 29 which can engage in a respective one of two recesses 30 on the locking rocker arm 28 which is urged by a spring 31 against the locking noses 29th
  • the levers 20 have lugs 32 against which leaf springs 33 which are fastened to the support 9 are supported.
  • the leaf springs 33 are equipped with stops 34 against which the raised levers 20 bear.
  • the scanning lugs 26 arranged on one side of the feeler levers 25 can cooperate with one of the control cams 13 arranged next to one another, while the sensing lugs 27 arranged on the other side of the feeler levers bear against a vibrating frame 35 which is supported in the carrier 9 by means of an axis 36 is stored.
  • the swing frame 35 is connected to a pin 37 on which a tie rod 38 engages, which is connected in a known manner to a needle bar pendulum mounted in the upper arm 1, in which a vertically movable needle bar 39 is guided.
  • the swing-out width of the needle bar 39 is controlled by actuating one or more of the operating elements 24.
  • an operating element 24 When an operating element 24 is depressed, the associated lever 20 is pivoted downward and its latching lug 29 snaps into the lower recess 30 of the latching rocker 28.
  • the locking rocker 28 swings out against the tension of the spring 32, a lever 20 previously locked in the recess 30 is pressed upward by the associated leaf spring 33 against the stop 34 designed to be resilient for noise damping.
  • the locking lug 29 of the lever 20 lies freely in the upper recess 30.
  • the feeler lever 25 articulated on it is brought into contact with the associated control cam 13 and the swing frame 35.
  • the selected control cam 13 thus swings the oscillating frame 35 via the associated feeler lever 25, which swings out the needle bar 39 according to the curve shape of the selected control cam 13 via the associated pin 37 and the pull rod 38.
