従って前記の揺動角度かゼロの場合を示している。FIG. 8 schematically shows the operating state of the feed adjustment arm 33 in the feed amount adjustment device. Without,
Therefore, the case where the above-mentioned swing angle is zero is shown.
いま、ミシンの主軸２の回転に応じて送り用正面カムか
ら連結棒２５を介して一定の揺動運動が揺動腕２９に伝
えられる。Now, in accordance with the rotation of the main shaft 2 of the sewing machine, a constant swinging motion is transmitted from the front feeding cam to the swinging arm 29 via the connecting rod 25.
この揺動腕２９の長溝２８に嵌合されている角駒３８の
位置が第８図のＡの状態にあるときは送り調節腕３３の
揺動角θ１は最大となり、従って送り歯３９の布送り量
Ｘは最大となる。When the position of the square piece 38 fitted in the long groove 28 of this swinging arm 29 is in the state A in FIG. The feed amount X becomes maximum.
次にナツト３６をゆるめて角駒３８の位置を前記長溝内

って送り歯３９に与えられる布送り量Ｘは第８図のＡの
場合よりも小さくなる。Next, loosen the nut 36 and slide the square piece 38 in the long groove toward the mounting shaft 27 to shorten the arm length and set it so that it is located near the mounting shaft 27. 8
In the state of B in the figure), the swing angle α of the swing arm 29 is given by the front feed cam as in the case of A in FIG. 27, the swing angle θ2 given to the feed adjustment arm 33 is smaller than the swing angle θ1 shown in FIG. smaller than the case.
この状態からさらに角駒３８を移動させて、角駒３８と
軸２７とが同軸線上になった第８図のＣの位置に角駒３
８を設定すると、腕長さは零となり、送り調節腕３３に
は揺動角が与えられず、θ３−０となり送り歯３９の布
送り量はゼロとなる。From this state, the square piece 38 is further moved to position C in FIG. 8, where the square piece 38 and the shaft 27 are coaxial.
When 8 is set, the arm length becomes zero, no swing angle is given to the feed adjustment arm 33, and the value becomes θ3-0, and the cloth feed amount of the feed dog 39 becomes zero.
なお、符号Ｙは針棒の横方向移動巾、即ち千鳥中を表わ
している。Note that the symbol Y represents the horizontal movement width of the needle bar, that is, the zigzag movement.
第９図Ａ、Ｂはそれぞれ角駒が第８図のＡ、Ｈの状態に
ある場合における千鳥縫ミシンの縫模様を表わした図で
ある。FIGS. 9A and 9B are diagrams showing the sewing patterns of the zigzag stitch sewing machine when the square pieces are in the states A and H of FIG. 8, respectively.
これらの模様において、図中の丸印は針が布に落ちた点
を表わし、またそれらをつないだ太線は縫成する糸を表

即ち、これらの模様は図のａ＝ｆにて円板５が１回転し
て一模様が完成するもので、従って主軸２が６回転して
円板５が１回転する割合である。That is, these patterns are completed by one rotation of the disk 5 at a=f in the figure, and therefore the ratio is that the main shaft 2 rotates six times and the disk 5 rotates once.
第１０図の模様は円板５を軸１から取り外して別の千鳥
用正面カム溝及び送り用正面カム溝が形成された円板を
軸１に取り付けて縫成された変形千鳥縫模様である。The pattern shown in Figure 10 is a modified zigzag stitch pattern that is sewn by removing the disk 5 from the shaft 1 and attaching it to the shaft 1 with a disk on which another front cam groove for zigzag and a front cam groove for feeding are formed. .
この場合は布送りが前進縫ばかりでなく、Ｃとｆの範囲
で後進繰送りとなるものであり、送り方向は前進縫、後
進縫、あるいは送り停止の任意の位置に設定され得るよ
うになっている。In this case, the fabric feed is not only forward sewing but also backward feeding within the range of C and f, and the feeding direction can be set to any position of forward sewing, backward sewing, or feeding stop. ing.

節することができる効果がある。As described above, according to the present invention, unlike conventional sewing machines, there is no need for a complicated structure in which the feed drive and feed adjustment are separated, and the displacement of the driven joint of the feed front cam device is controlled by the feed dog via the link device. This has the effect of directly converting the reciprocating rotational movement of the feed shaft connected to the feed shaft into a reciprocating rotational movement, and further, that the rotation angle can be easily changed to adjust the feed amount.

煩わしさ、不経済な欠点が解消できるものである。Therefore, according to the present invention, in order to adjust the feed amount,
There is no need to replace the cam with other cams with different feed displacement amounts by changing the cam groove shape, etc., and can be changed by adjusting the connection position between the swing arm of the slidable member and the feed adjustment arm. As a result, the feed amount can be changed steplessly, which eliminates the troublesome and uneconomic disadvantage of having to prepare a large number of feed cams for a cam device.
