ドフレーム本体1に設けた軸33に固定した揺動
レバー34の上端に固定され、第11図のような
形状をしている。 In any of the above conventional examples, the lower looper 32 is fixed to the upper end of a swing lever 34 fixed to a shaft 33 provided on the bed frame main body 1, and has a shape as shown in FIG.
すなわち、作業者側から見て、左側に糸孔35
があり、この糸孔に挿入した糸はルーパ前面の糸
溝36を通りルーパ先端の糸孔37に挿入するよ
うになつている。 In other words, the thread hole 35 is located on the left side when viewed from the operator's side.
The thread inserted into this thread hole passes through a thread groove 36 on the front surface of the looper and is inserted into a thread hole 37 at the tip of the looper.
ベツドフレーム本体1の前部左側は第9図、第
10図に鎖線で示すように、開閉自在の補助ベツ
ド40となつているから、下ルーパ32への糸通
しにさいしては、まず図示省略してある前面カバ
ーを開き、ついで、補助ベツド40を開く。 The front left side of the bed frame main body 1 is an auxiliary bed 40 that can be opened and closed, as shown by chain lines in FIGS. 9 and 10. Open the front cover and then open the auxiliary bed 40.

くぐらせて下ルーパ32の後部側に引き出す。 On the other hand, the thread pulled out from the bobbin spool above the sewing machine (not shown) is passed through the thread tension device, thread guide, etc. (not shown) at the top of the sewing machine, and then passed through the thread guide 41.
After hanging it, it is pulled out to the rear side of the lower looper 32 by passing under the fixed knife 5 and throat plate 3 or through the opening 42 in the left side wall 6 of the bed frame main body 1.
こうして下ルーパ32の後部に引出した糸は下
ルーパ32の左側の糸孔35に通し、糸溝36を
経て右側の剣先の糸孔37に挿通して完了する。 The thread thus drawn out to the rear of the lower looper 32 is passed through the thread hole 35 on the left side of the lower looper 32, passes through the thread groove 36, and is inserted into the thread hole 37 at the tip of the right sword to complete the thread.
上記で明らかなように下ルーパ32への糸の挿
入はきわめて手数がかかるものであるが、これに
加えて、下ルーパ32の前部には第9図の例では
固定メス5と可動メス11とがあり、第10図の
場合は、可動メス11は前向きにできるが固定メ
ス5はそのままである。
As is clear from the above, it is very time-consuming to insert the thread into the lower looper 32, but in addition to this, in the example shown in FIG. In the case of FIG. 10, the movable knife 11 can be moved forward, but the fixed knife 5 remains as it is.
このため、固定メス5やこの固定メス5を取付
ける部品あるいは固定メス5を支えるベツドフレ

As mentioned above, this invention is located in front of the lower pearl and obstructs the view when threading the lower looper.
Since only the fixed knife, or both the fixed knife and the movable knife, which can be an obstacle to threading work, are attached to the movable part of the bed frame, which is rotatably attached to the bed frame body, this By rotating and opening the bed frame movable part in a direction away from the lower looper, the front part of the lower looper is completely opened.
従つて下ルーパを直接目視しながら糸通しがで
き、作業者の指先がルーパに接近し易くなるので
糸通し作業がきわめて容易となり、栽縫準備に要
する時間が短縮できるという効果がある。 Therefore, threading can be carried out while directly viewing the lower looper, and since the operator's fingertips can easily approach the looper, the threading operation becomes extremely easy and the time required for preparation for sewing can be shortened.
