置に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention includes an adjustment slider inserted into an arc-shaped longitudinal movement adjusting arm fixed to a shaft for longitudinal movement of the lower feed dog.
A slider operating arm rod for sliding the slider on the adjustment arm is fixed to the base end of the sleeve inserted into the shaft for forward and backward movement of the upper feed dog, and a lever for moving on the scale plate is attached to the tip, The slider and the tip of a swinging rod fixed to the base end of the shaft for back and forth movement of the upper feed dog are connected by a swing connecting rod, and the slider is connected to the tip of the shaft for back and forth movement of the upper feed dog to move the upper feed dog back and forth. By connecting the movement device and adjusting the lever onto the scale plate, the slider is moved by the slider actuating arm onto the adjusting arm through the sleeve, and a constant oscillation of the shaft for the back and forth movement of the lower feed dog is performed. This device relates to a device that adjusts the size of the dynamic movement by adjusting the position of a slider on the adjustment arm and transmits it to a shaft for back-and-forth movement of the upper feed dog, and adjusts the back-and-forth movement of the upper feed dog through the upper feed dog back and forth movement device. It is something.
従来、この種オーバーロツクミシンの上送り歯

のである。 Conventionally, the upper feed dog of this type of overlock sewing machine moves in an elliptical trajectory with a constant width in the front-rear direction, so the amount of back-and-forth movement of the upper feed dog is constant and the amount of upper fabric fed by the upper feed dog is constant. , Due to the thickness of the fabric and the sewing of different materials, the feed amount of the upper fabric may be greater or less than the feed amount of the bottom fabric, which may cause creases, shrinkage, and the end of the finished stitch. This method has a major drawback in that it does not produce a good sewing effect when shirring the upper fabric, etc. due to the occurrence of fabric displacement, etc.
然るに本発明に於いては上送り歯の前後運動量

製効果を発揮できるもので、利用価値大である。 However, in the present invention, the magnitude of the back-and-forth movement of the upper feed dog can be easily adjusted by moving a lever on the scale plate, so the feed of the upper and lower fabrics can be adjusted by adjusting the thickness of the fabric, sewing different materials, etc. It is possible to make the amount uniform so that there is no difference in the amount, or to increase the amount of feed of the upper fabric than that of the lower fabric as appropriate, and to avoid the occurrence of the above-mentioned seam wrinkles, seam shrinkage, and fabric displacement, and to shirring the upper fabric. It can also exhibit good sewing effects and has great utility value.

Reference numeral 2 denotes a circular arc-shaped longitudinal movement adjusting arm, which has a circular arc-shaped portion 2a at its distal end, and its base end is inserted into and fixed to the shaft 1. Reference numeral 3 denotes a slider which is slidably inserted into the arcuate portion 2a of the adjusting arm 2, and has shafts 4, 4a protruding from both sides. Reference numeral 5 denotes a shaft for moving the upper feed dog back and forth, and a swinging rod 6 is fixed to the base end, and the tip of the swinging rod 6 and the shaft 4a on one side of the slider 3 are connected by a swinging connecting rod 7. It is rotatably connected and performs rocking rotation movement together with the shaft 1. Reference numeral 8 denotes a sleeve, into which the shaft 5 for moving the upper feed dog back and forth is rotatably fitted. Reference numeral 9 denotes an arm rod for operating the slider 3, the proximal end of which is inserted into and fixed to the proximal end of the sleeve 8, and the distal end thereof forms a bifurcated portion 9a. Reference numeral 10 denotes a square piece, which is rotatably supported on the shaft 4 on the other side of the slider 3, and is slidably inserted into the bifurcated portion 9a of the operating arm rod 9. Reference numeral 11 denotes a lever, which is attached to the tip end 8 of the sleeve 8.
A, it moves on a scale plate 13 fixed to the sewing machine body 12, and can be fixed at any location on the scale plate 13 by means of an adjustment screw 14 attached to the tip. Reference numeral 15 denotes an arm for moving the upper feed dog back and forth, and its base is inserted into and fixed to the tip of the shaft 5 for moving the upper feed dog back and forth. Reference numeral 16 denotes a known upper feed dog back and forth movement device, which includes an upper feed dog mount 18 that is slidably fitted into the upper feed dog mount guide 17.
It consists of 19 is a longitudinal movement connecting rod,
It connects the tip of the swing arm 15 and the base of the upper feed dog mount 18 of the back and forth movement device 16. 20 is an upper feed dog attached to the tip of the upper feed dog mount 18, and 21 is a cloth presser. The present invention has the above-described configuration, and when using this, when the screw rod 14 is loosened and the lever 11 is moved onto the scale plate 13, the sleeve 8 to which the tip end 8a is fixed will move the lever 11. As a result, the operating arm 9, which is fixed to the base end of the sleeve 8, rotates around the shaft 5 for forward and backward movement of the upper feed dog, and the slider 3 moves from the bifurcated part of the arm 9. 9a, the arcuate portion 2a of the longitudinal motion adjusting arm 2 is slid to the proximal end portion via the square piece 10. Now, when the lever 11 moves in the direction of arrow A in FIG.
is moved toward the tip, and a certain amount of rocking rotation of the shaft 1 for back-and-forth movement of the lower feed dog is transmitted to the slider 3, and the increased amount of rocking rotation is transmitted to the rocking connecting rod 7 and the rocking rod. 6 to the shaft for the back and forth movement of the upper feed dog, and is converted into the amount of swing in the back and forth direction via the upper feed dog back and forth swinging arm 15, the back and forth swing connecting rod 19 and the upper feed dog back and forth movement device, The amount of back and forth rocking of the upper feed dog 20 increases. Conversely, when the lever 11 moves in the direction of arrow B in FIG.
moves the arcuate portion 2a toward the proximal end, and a certain amount of oscillating rotation of the shaft 1 is transmitted to the slider 3 in a small amount, and the decreased amount of oscillating rotation is similarly converted, and the amount of rotation of the upper feed dog 20 is changed. The amount of back and forth rocking is reduced.
