Definitions

  • the present invention relates to zig-zag sewing machines and is particularly concerned with control and switching mechanism adapting such machines for ordinary sewing operations as well as for automatic or semi-automatic operation, for example, to produce button holes or the like.
  • Zig-zag sewing machines are normally constructed in a manner that they have special manipulating means which are independent of one another by means of which the stitch width or cross-over, the stitch position and the material feed operation are adjustable. It is possible to produce a large number of difierent ornamental stitches with such a zig-Zag sewing machine. It is even possible to sew a button hole with these individual setting means, but this requires especially competent operation which cannot be generally expected of the normal seamstress.
  • so-called automatic sewing machines are known which are provided with a nest of guiding or control cams. This cam nest can be arranged in such a manner that by properly adjusting the earns the sewing of a button hole takes place automatically or semi-automatically, depending on whether or not the control cam nest is driven by the shaft of the sewing machine.
  • the invention utilizes a known zig-zag sewing machine having setting cams for the stitch width and the stitch position arranged axially and independently of one another and having associated manipulating means.
  • the cam disks are on the inside of a cover plate which closes an aperture in the machine housing and the associated manipulating devices are on the outside of said plate.
  • the invention in the first place, provides that in such a zig-zag sewing machine which is known per se the control arrangement is provided with an additional control cam disk for the material feed and manipulating means therefor.
  • the three handles for the stitch width, the stitch position and the material feed can be coupled with one another.
  • the arrangement is preferably made in such a manner that the cam disks are formed along a part of their circumferences in a manner to make the machine useable as a normal zig-zag machine, while the curves along the other part of the circumferences of these cam disks are constructed for semi-automatic button hole production.
  • cam disks for the overstitch width, the stitch position or location and for the material feed thus serve along one part of their circumferences to permit use of the sewing machine as a true zig-Zag sewing machine, while another part of the circumferences of the same setting cam disks is used, for example, for the semi-automatic sewing of a button hole.

  • FIG. 6 is a perspective view of the setting knob
  • FIG. 7 is a perspective illustration of the setting mechanism with the knob removed
  • FIG. 8 is a front view of the setting mechanism shown in FIGS. 4 to 7,
  • FIGS. 9 10 and 11 are rear views of the control disks in the position for sewing straight or zig-zag seams
  • FIGS. 12, 13 and 14 are rear views of the cam disks in the position for sewing the left bead of a button hole for lingerie
  • FIG. 15 is a section through a further embodiment of a setting mechanism taken along line XVXV and looking in the direction of the arrows in FIG. 16, and
  • FIG. 16 is a rear view of the setting mechanism with the guiding cam disks in accordance with FIG. 15.
  • the arm 1 of housing 1, 59 of the sewing machine supports the main shaft 2 which by way of the pair of worm wears 3, 4, drives the cam shaft 5 journalled in bearing 6. At its upper end, the cam shaft 5 supports the cam 7.
  • the cam is engaged by the jaws of claw lever 8 (see FIG. 2) which is linked at its free end at 9 to the operating lever 10 of the needle bar oscillator 11.
  • the operating lever 19 is secured to the needle bar oscillator which oscillates about pintles 12, 12' journalled in the housing and it supports the needle bar 13 in a known manner for reciprocating motion. As shown in FIG.
  • the claw lever 3 is provided with a pin 14 which supports the slide member 15, which slidingly engages a slot 16 of slotted member 17 which has a cylindrical stud (not shown) by means of which it is rotatably supported endwise of the shifting lever 18.
  • the shifting lever 13 is rockable about a pin 19 which is secured in the arm 1. If the slot 16 in member 1'7 is disposed at right angles with respect to the imaginary connecting line between 9 and pin 14 the claw lever 8 is caused to rock back and forth as the cam 7 rotates about pivot without the claw lever 8 or the pivot pin 9 being shifted longitudinally of the axis of the claw lever.
  • the needle bar oscillator 11 and therefore needle bar 13 does not move laterally transversely of the material feed direction so that in this position of slot 16, the sewing machine makes straight stitches.
  • the claw lever 8 moves back and forth along its longitudinal axis in addition to moving about pivot pin 9. In this manner the needle bar oscillator 11 or needle bar 13 will produce lateral deflections of more or less magnitude transversely of the direction of material feed and thus produce Zig-zag stitches.
  • T 0 permit setting of the position of slot 16
  • a lever arm 34 is provided on slotted member 17 which carries a pin 33.
  • a link 31 is connected with lever arm 34 by means of this pin 33 and is also connected by means of pin 32 with lever arm .26 of angular lever 2d, 26'.
  • the angular lever 2d, 21) is journalled upon a stud 19 secured to arm 1.
  • the shifting lever 18, lever arm 34 and link 31, as Well as the lever arm 20 of angular lever 21), 2t) define a parallelogram.
  • a pin 26 is provided to which is linked one end of a connecting bar 27 while the other end is threadedly connected by means of screws 43 to the connecting bar 41.

  • Shifting the position of slot 16 of member 17 causes the machine to produce zig-Zag stitches which are symmetrical with respect to center position. If it is desired to produce zig-zag scams or straight seams along the right or left side with respect to the center position, it is necessary to move the shifting lever 18 about bolt 19.
  • the shifting lever 18 has a lever arm 35 at its end which carries the pin 36 (see FIG. 2). This pin 36 supports at the same time one end of the connecting bar 39. At its other end the connecting bar has two screws 42 by means of which the connecting bar 40 is threadedly linked to the connecting bar 39.
  • This bar 49 is provided in the region of the two screws 42 with a longitudinal slot (not shown) for controlling the spacing, while the other end of the connecting bar 4-0 is linked by means of bolt 51 to the follower lever 52 (FIG. 4) which is journalled upon the bolt 46.
  • the manner in which the setting means 99 and 163 operate the control mechanism of the sewing machine is described hereinafter in a subsequent part of the specification.

  • the looper drive shaft 58 is driven at a ratio of 1:1 by means of belt 56 mounted on the two pulleys 55 and 57.
  • a cam 60 is provided upon the looper drive shaft which is engaged by the jaws of claw lever 61.
  • One end of the claw lever 61 is linked by means of bolts 62 to an arm 63 of the feed shaft 64 while the other end of the claw lever carries a bolt 7% on which a sliding member 71 is supported. This member slides in a slot '72 of guide block 73 which is rotatably journalled by means of its cylindrical stud 39 (see FIG.
  • a toothed head or feed dog 69 is secured to the feed bar 67.
  • the pivotal movement of the feed shaft 64 is transferred by way of arm 65, feed bar 67 and feed dog 69, and in this manner the advancing movement of the material is obtained.
  • an arm 74 is provided on member 73 which carries the pin 75. Due to the pressure of spring 91 this pin 75 engages the lower edge of the slot 536 of the connecting bar 76.
  • the connecting bar 76 is linked by means of bolt 79 tolever arm 78 (FIGS. 1 and 3).

  • the point 112 (FIG. 11) of this follower lever 44 rests against the cam 87, and the point 113 against the cam 86.
  • the sewing machine produces straight stitches. If the knob is turned to the right, the follower lever 44 is shifted by means of the cam portions 126, 121 and thus the magnitude of the zig-zag stitches is changed.
  • the cam portion 85 (FIG. 9) is not utilized. Consequently the follower point 122 of the screw 103 provided in the follower lever 83 rests against a concentric part of the cam 85.
  • the connecting bar 82 is linked to the pin 85' adjustably mounted in longitudinal slot 118 of follower lever 83 (FIG. 4) and is provided at its lower end with a longitudinal slot 81 which receives the pin 75 of the arm of slide member 74 (FIG. 3).

  • the nut 109 serves for locking the adjusted position thus found. While it is possible to adjust the equal stitch length with forward and backward stitches by means of the screw 1%, the setting of the stitch length is provided for by shifting the pin $5 in the longitudinal slot 118 of the follower lever 83. in the desired position the pin 85 is securely held in position.
  • cams 8d and 37 are formed in such a manner that the follower points 112 and 113 of the lever 44- have not yet reached the lowest or highest point of the cam during sewing of the beads (see FIG. 12), it is possible by adjusting the abutments 11%, 111 in the longitudinal slots 117, 116, respectively to change the width of the bead and the distance of the two beads from one another (FIG. 7).
  • cams 86, 8'? for the over stitch width and the cam $5 for the stitch length are shifted together by about 180 during shifting from optional sewing to button hole sewing, while the cam 88 retains its position for the stitch location because the cam sections 118, 119 of cam 83 are used for the random setting of the stitch location (see FIG. 10) as well as for the sewing of button holes.
