送り上下腕24が揺動せしめられるから、上送り上下クラ
ンク22が運動せしめられる。The present invention has the above-mentioned structure, and its operation will be described below. First, by operating the rotating plate 37, the guide shaft 2 is rotated so that the tip of the presser bar sticking plate 32 is pressed down. When the sewing machine is operated by removing it from the lower surface of the rod feed 14 (see FIG. 2), the upper feed upper and lower arms 24 are swung in conjunction with the rotation of the drive shaft, so that the upper feed vertical crank 22 is moved. .

ロ25の下降が停止せしめられる。The upper feed vertical crank 22 swings around the horizontal axis 21
When 25 is lowered to the same height as the horizontal axis 21, the guide base 26 and the engaging plate 30 integrated with the forked portion 27 that holds the roller 25 are also lowered at the same time,
The tip end portion 28 of the engaging plate comes into contact with the upper surface of the presser bar tack 14 to stop the lowering of the roller 25.

押え棒１を介して押え棒調節ばね15と共に押え足13を針
板面Ｈに圧接せしめる（第４図参照）。At this time, the spring force of the upper feed presser spring 19 causes the engaging plate 28 to act on the upper surface of the presser bar duck 14 via the roller 25 and the guide base 26 to cause the presser bar 13 to press the presser foot 13 via the presser bar 1. It is pressed against the needle plate surface H (see FIG. 4).
次に前記上送り上下腕24が揺動して元に戻れば前記上
送り上下クランク22も元の位置に戻され、前記上送り歯
10は針板面Ｈに着地せしめられる。Next, if the upper feed upper / lower arm 24 swings and returns to the original position, the upper feed upper / lower crank 22 also returns to its original position.
10 is landed on the needle plate surface H.
この時上送り押えばね19のバネ力は上送り押え棒ダキ
５に作用して上送り歯10を針板面Ｈに圧接せしめる。At this time, the spring force of the upper feed presser spring 19 acts on the upper feed presser bar rod 5 to press the upper feed dog 10 against the needle plate surface H.
一方、押え足13には押え棒調節ばね15だけが作用してい
る（第５図参照）。On the other hand, only the presser bar adjusting spring 15 acts on the presser foot 13 (see FIG. 5).
上記の如く上送り上下クランク20の運転中、前記押え
足13は常に針板面Ｈに着地しながら押え棒調整ばね15の
作用を受け、更に上送り押えばね19のバネ力が交互に作
用せしめられる（第４図及び第５図参照）。As described above, while the upper feed vertical crank 20 is in operation, the presser foot 13 always receives the action of the presser bar adjusting spring 15 while landing on the needle plate surface H, and the spring force of the upper feed presser spring 19 is alternately applied. (See FIGS. 4 and 5).
この状態が常時載置状態である。 This state is the constant placement state.

第７図に示す如く上昇せしめることとなる。Next, the rotating plate 37 is operated to rotate the guide shaft 2 so that the tip of the holding bar duck holding plate 32 is rotated to the lower surface of the holding bar duck 14 (see FIG. 3) (holding bar duck). The tip of the holding plate 32 can be rotated only when the upper feed dog 10 is in the upper position. The state in which the holding rod daki 14 is held by the tip 28 of the upper engaging plate 30 (see FIGS. 6 and 7). When the sewing machine is operated, the upper feed upper / lower arm 24 swings in conjunction with the rotation of the drive shaft, and then the upper feed vertical crank 22 swings. When the upper feed vertical crank 22 swings from the state shown in FIG. 6, the work clamp 13 lands on the needle plate surface H and the upper feed dog 10 is separated from the needle plate surface H. It swings around 25 and the horizontal axis 21
When descending to the same height as 25, the upper feed dog 10 is landed on the needle plate surface H. When the needle plate surface H of the upper feed dog 10 lands, the swing center of the upper feed vertical crank 22 moves to the horizontal axis 21,
Therefore, the presser bar duck 14 is raised by way of the guide base 26 for holding the rollers and the presser bar duck holding plate 32, so that the cloth presser 13 attached to the lower end of the presser bar 1 fixed to the presser bar duck is placed first. As shown in Fig. 7, it will be raised.
続いて上送り上下クランク22が揺動せしめられると、
前記布押え13が下って針板面Ｈに着地し、上送り歯10が
針板面Ｈから離される状態となる（第７図参照）。Then, when the upper feed vertical crank 22 is swung,
The cloth presser 13 descends and lands on the needle plate surface H, and the upper feed dog 10 is separated from the needle plate surface H (see FIG. 7).
