Definitions

  • An apparatus for making a tucking curtain comprises a sewing machine with a presser foot, a slider slidably mounted on the base of the sewing machine and carrying a presser, a pair of upper and lower spatulas and a width setting bar located near under the arm head of the sewing machine.
  • the curtain cloth is laid over the spatulas and the width setting bar, folded back around the bar and passed under the spatulas to form a loop and then sewed along its seam for the first run while held by the pressersi'Then the upper spatula is raised apart from the lower to spread the looped cloth therebetween and simultaneously the tucking plate enters between the spaced spatulas to tuck in the looped cloth. whereupon theupper spatula is lowered and retracted together with the lower spatula and the width setting bar.
  • This invention relates to apparatus for forming tucks in curtains and the like regardless of the quality of the cloth which is involved in the tucking operation.

  • a sliding shaft 45 slidably supported at its middle by the slider 7 has on one end thereof a fixing plate 46 with a hole 47 for slidably receiving a bent portion 4 of the width setting bar 4 to be fastened to the fixing plate 46 by means of a set screw 48.
  • a connecting plate 49 pivotally connected at 51 to one end of a link 50, whose other end is pivotally connected at 55 to one end of a first push lever 52 swingably mounted on said vertical shaft 53.
  • the other end of said lever 52 is forced against a first cam 56 secured to said cam shaft 54 by means of a spring 57 stretched between the lever and the slider 7.

  • LK cycle sewing machine sewing machine
  • the cross slide mechanism for the slider comprises a motor 76 set on the base 8, a gear 78 fixed on the shaft of the motor, a disc 79 attached to the side of the gear 78, a gear 80 engaging the gear 78 and having a pin 81, a limit switch 82 so positioned as to be tripped by said pin 81, and a rod 84 pivotally connected at 85 with an eccentric pin 83 projecting from said disc 79 and at 86 with the support shaft 75 (See FIGS. 13 and 14).
  • the second presser comprises the presser foot of said LK cycle sewing machine and is located between the first presser 1 and the upper and lower spatulas 2 and 3 (See FIG. 1).

  • the push lever 91 is urged to engage at the other end a cam 93 fixed on the cam shaft 54 by means of a spring 94 stretched between said lever 91 and the slider 7 (See FIG. 21).
  • the first solenoid Upon turning on the switch for a first solenoid, a second solenoid and the sewing machine driving motor, the first solenoid will be energized and pull the connecting rod 40 downward by its attractive force.
  • the second arm lever 38 will then swing on the pivot 37 and cause, with one end thereof, the first arm lever 11 to swing upward about the pivot 15 against the action of the spring 13.
  • the first presser 1 will be elevated.
  • the first arm lever 11 swings upward as stated above, its projection 35 pushes the angled hook 33 upward against the tension of the spring 36 to cause the lower spatula arm plate 19 to rotate the rotatable shaft 17 (as shown by the arrow).
  • the lower apatula 3 will then move upward and at the same time lift the upper spatula 2 against the action of the spring 31, followed by the upward swing of the upper spatula arm lever 23 whereby the rotatable shaft 17 will be rotated and stop.
  • the second solenoid is energized simultaneously with the energization of the first solenoid thereby to elevate the second presser 6 which is constituted by the presser foot of the sewing machine (in a manner well known).
  • the cloth 70 is placed with one end portion thereof arranged over the upper spatula 2 and the width setting bar 4 while applying one longitudinal edge thereof to a ruler fixed to the slider 7. Thereafter, it is folded backward around the width setting bar and passed under the lower apatula 3 so that its leading end underlies the remaining portion of the cloth in a position under the first presser 1.
  • the cloth 70 is stretched from the width setting bar 4. It is needless to say that the lengthwise edge of the cloth 70 should be always held along the ruler 71 during that process.
  • a first button is pressed to disenergizes said first solenoid.
  • the first solenoid will reverse and the second arm lever 38 will swing back due to the action of the spring to lower its left-hand end, so that the first arm lever 11 which has been lifted up by the end of the second arm lever 38 will be let down swinging about the pivot 15. Accordingly the first presser 1 will come down to hold the cloth 70 on the working plate 7' of the slider 7.
  • a starting switch (not shown) is turned on, whereupon the second solenoid will be deenergized.
  • the second solenoid will then reverse to lower the second presser 6, which has been elevated, to hold the cloth 70 on the working plate 7' of the slider 7.
  • a third solenoid is energized to make a clutch of the sewing machine on whereby the sewing machine starts its operation as it now receives power from said sewing machine driving motor and rotates the cam shaft.
  • the cam 66 rotates and this rotation is converted into the traverse movement of the operating arm 67 which causes the slider 7 to traverse as the sewing needle 72 is sewing.
  • the proceeding of such operation is represented in the development chart of the cam shown in FIG. 17.
  • the sewing machine is an LK cycle machine 8 in which one cycle comprises two runs of sewing, it stops because of the disconnection of a clutch after the first run of sewing has been completed.
  • This stopping of the sewing machine is sensed by a limit switch which will operate a relay to energize the'second solenoid.
  • the second presser 6 is raised and stops, and this stop is electrically sensed to operate a relay (for this purpose refer to the circuit shown in FIG. 18) to drive motor 75, whose rotation is transmitted to the gear 78 to rotate it in the direction of the arrow in FIG. 13, causing rotation of the arm lever 84 to shift the slider 7 to the left (See FIG.
  • Each revolution of the gear 80 makes its pin 81 strike the limit switch 82 to stop the motor 76, so that the slider 7 will stop at the leftmost position (See FIG. 14).
  • the second cam 43 causes the second push lever 42 to push the arm 41 to rotate the rotatable shaft 17 so that the upper spatula 2 will be lifted up to some distance from the lower spatula 3 and therefore the cloth 70 will be opened (See FIG. 19).
  • the third cam 65 causes the tucking plate 5 to be swung about the pivot through the action of the third push lever 63 and the link 61 so that the tucking plate will be brought between the upper spatula 2 and the lower spatula 3.
  • the second cam 43 causes the arm 41 and the shaft 17 to reverse to let the upper spatula 2 down. Accordingly a tuck is formed on the cloth 70 by means of the first presser 1, the upper spatula 2 the lower spatula 3 and the tucking plate 5 (See FIG. 4).
  • the third cam reverses the third push lever and the link 61 to draw out the tucking plate from between the upper spatula 2 and the lower spatula 3.
  • the forth cam 93 causes the upper and the lower spatulas 2 and 3 to be retracted through the action of the forth push lever 91, the link 89, the connector plate 88 and the support plate 28 (See FIG. 5).
  • a projection 95 formed on the cam shaft strikes the limit switch 96 to stop the motor 73.
  • the signal from the limit switch 96 will excite a relay to deenergize the second solenoid and therefore the second presser 6 will come down.
  • the third solenoid is energized to make the clutch of the sewing machine make the slider 7 traverse as'sewing is performed.
  • the second run of sewing with the LK cycle sewing machine comes to an end.
  • the first solenoid and the second solenoid become deenergized and the first presser 1 and the second presser 6 are lifted.
  • the clutch is then disconnected. This disconnection of the clutch is sensed by a limit switch to excite a relay to start the motor 73 and the motor 76 to rotate the cam shaft 54, causing upper and lower spatulas 2 and the width setting bar to proceed forward to return to their initial positions. The operation of the motor 76 also causes the returning of the slider 7 rightward to its initial position. The cloth may now be taken out. A tuck has thus been formed in the cloth as shown in FIG.
