  • 33/23 15 C an one armed lever pivoted on the template and having an oblong hole in which the crank pin engages, [56] References and and a roller pivoted on the lever and bearing against the gear pinion, for driving the magnetic roller out of UNITED STATES PATENTS the comer- 3,400,608 9/ 1968 Laws ..74/569 2 Claims, 4 Drawing Figures PATENTEDDCT 3 i972 3,695,194
  • a device is already known in which the magnetic power generator independent of the motor driven roller is pivoted about the axis of the driven roller in such a manner that the direction of the initial power lies in a plane which is in the connecting line between the axis of the roller and the point of contact between the roller and the template, while a small air gap is preservedinfront of the template.
  • a further object of the invention is to avoid an interruption of the feed of the magnetic roller after it arrives at an internal corner of the template.
  • FIG. 1 is a front view, partially in section, of a template-controlled automatic sewing device for stitching cuffs or other small parts in a continuous sequence;
  • FIG. 2 is a sectional top plan view on the mechanism according to the invention, taken along line ll-Il of FIG. 1;
  • FIG. 3 is a section taken along line III i ll] of FIG. 2 and FIG. 4 is a perspective view of the mechanism in an enlarged scale.
  • a magnetic roller 8 (FIGS. 2,4) secured to a driven shaft 9 bears upon the peripheral edge 7 of the template 6.
  • the shaft 9 is surrounded by a solenoid 10 which is received in a supporting arm 12 carrying the sewing machine 1 l.
  • the shaft 9 is driven by a motor 15 (FIG. 1) by means of bevel wheels l3, 14.
  • the turntable 1 is carried by a shaft 16 which is pivoted on a frame 17 provided with a jib 18, on which a swingable link arm 19 is swingably supported. The free end of the latter is connected with the supporting arm 12.
  • a motor 22 drives the needle bar 21 of the sewing machine 1 l.
  • the needle bar 21 carries a needle 20 and is coaxially disposed with the shaft 91 Furthermore, secured to the shaft 9 is a gear pinion 23 for meshing with a gear wheel 25, which is rotatably arranged on the template 6 by means of a bolt 24.
  • the mechanism 26 is in drivingconnection with the gear wheel 25, and consists of an one-armed lever 27, which is pivoted aboutan eccentric bolt 28 secured to the template 6.
  • the one-armed lever 27 carries on its free end 27' a loose roller 29 and is provided with'an oblong hole 30 for engaging with a crank pin 31 secured to the gear wheel 25.
  • a tension spring 34 Between the crank pin 31 and an extension 32 of a bolt 33 carrying the loose roller 29, is a tension spring 34.
  • Theclearance between the loose roller 29 and the gear pinion 23 can be eliminated by means of the eccentric bolt 28, so that the traversing motion of the lever 27 begins immediately after meshing of the gear wheels 23, 25.
  • a template follower mechanism including a template having internal corners, a magnetic roller driven by a motor and bearing against said template, a rotatably driven gear pinion mounted coaxially with said roller, a gear wheel, means pivotally attaching said gear wheel to said template adjacent one of said internal corners for cooperating with said gear pinion when said roller enters said internal comers, and means in driving connection with said gear wheel for moving said roller and said gear pinion out of said internal corners into a new path after entering said comers, said means comprising an one-armed lever provided with an elongated hole and means pivotally attaching said one armed lever on said template, a loose roller carried by the free end of said one-armed lever and abutting against said gear pinion upon its arrival in said internal corner, and a crankpin mounted in said gear wheel and engaging in said elongated hole of said one-armed level.
  • a support means a turntable, means pivotally securing said turntable on said support means, a template having internal corners, means attaching said template below said turntable, workpiece clamping means above said turntable, a link arm, means swingably attaching said link arm to said support means, a supporting arm pivtoed on said link arm, a driven magnetic roller engaged with the peripheral edge of said template, means attaching said magnetic roller on said supporting arm, a sewing machine carried by said supporting arm and having a vertically reciprocating needle, a gear pinion coaxially mounted on said driven magnetic roller, a gear wheel, means pivotally attaching said gear wheel to said template adjacent of said internal corners for cooperating with said gear pinion when said roller enters said internal corners, an one-armed lever provided with an oblong hole and means pivotally securing said one-armed lever on said template, a loose roller carried by the free end of said one-armed lever and abutting against said gear pinion upon its arrival
