It comprises a bush support, a bush non-rotatably fitted to the bush support, a connector rotatably fitted to the bush, and a pair of support side plates connecting the connector and the rope. The bush support is composed of a toothed plate and can change the meshing position with the cam lever. Thereby, the meshing position of the bush support can be properly specified according to the warp opening angle. In order to lubricate the sliding contact portion between the bush that moves together with the bush support and the connector, for example, as shown in Japanese Utility Model Laid-Open No. 192980/1983, apply a coating member such as felt on the swing trajectory of the connector. It is necessary to supply lubricating oil such as by arranging or dripping oil from the oil pan onto the rocking arrangement position of the connector when the heald frame is moved to the lowest position when the cam lever has the longest stationary period.

The lubricating oil reaches the rope through the supporting side plate. The lubricant that travels along the rope hardens the fly dust that accumulates on the rope. However, if the fly dust hardened by the lubricant is caught between the rope and its guide roller, there is a risk of a poor opening or rope breakage. or,
The oil that travels along the rope drips onto the floor, and the soiling of the floor near the loom installation interferes with human equipment. Furthermore, such leakage results in waste of lubricating oil.

A bush 17 is fitted and fixed to the bush support 16, and a connector 18 is rotatably fitted to the bush 17. The connector 18 is a pair of supporting side plates.
The pull-down rope 12 is supported between the front end portions of 19 (only one is shown), and is wound around the support shaft 20 between the base end portions of the support side plates 19 so as to incline upward from the guide roller 23 side to the cam lever 11 side. It is hung. The connecting position of the connector 18 is appropriately adjusted along the tooth portion 11b of the cam lever 11 by changing the warp yarn opening angle, and the attachable region of the connector 18 with respect to the cam lever 11 covers the entire tooth portion 11b.

The brushes 26 are suspended and supported by a support bar 28 attached to the side frame 1 at equal intervals.
Hairs 26b are radially planted on the peripheral surface of 26a.
The length of the bristles 26b is such that adjacent brushes 26 come into contact with each other, and the pull-down rope 12 is passed between the adjacent brushes 26.

ロープ12側に向かう。An oil pan 21 is installed above the oil bath 15a, and the lubricating oil in the oil bath 15a is pumped up to the oil pan 21 by a pump 22 in the cam box 15. The lubricating oil pumped up to the oil pan 21 is dripped from the oil hole 21a of the bottom wall of the oil pan 21 onto the swinging position of the connector 18 corresponding to the lowest moving position of the heddle frame 14, and then onto the connector 18. The dropped lubricating oil enters the sliding contact portion between the connector 18 and the bush 17.
As a result, the sliding contact area between the connector 18 and the bush 17 is lubricated, but the lubricating oil dropped from the oil pan 21 overflows from this sliding contact area, albeit little by little. Therefore, the lubricating oil that overflows is the cam lever 11 and the support side plate.
The lubricating oil that traveled along 19 and traveled through cam lever 11 is the cam box.
Although it returns to the inside of 15, the lubricating oil transmitted through the support side plate 19 is pulled down toward the rope 12 side.

制され、織機設置場所の床上への滴下もない。However, the lubricating oil transmitted from the support side plate 19 to the pull-down rope 12 is wiped by the bristles 26b of the brush 26 that slides relative to the pull-down rope 12, and moves to the bristles 26b side. Hair 26
The lubricating oil that has moved to the b side travels down the brush 26,
Drips from the bottom of to the induction oil pan 25. The lubricating oil dropped on the induction oil pan 25 is the induction oil pan 25.
To the cam box 15. Therefore, the lubricating oil that has propagated through the portion of the pull-down rope 12 that is inclined higher than the brush 26 has the pull-down rope that is inclined lower than the brush 26.
The lubricant oil does not reach the part of the pull-down rope 12 that contacts the guide roller 23. As a result, the fly cotton is prevented from adhering to the contact portion between the guide roller 23 and the pull-down rope 12, and the fly cotton hardened by the lubricating oil is caught between the pull-down rope 12 and the guide roller 23. Poor opening and broken rope are prevented. Moreover, since the lubricating oil overflowing from the sliding contact portion between the connector 18 and the bush 17 is returned to the cam box 15 via the guiding oil pan 25, the waste of the lubricating oil is suppressed, and the loom installation place There is no dripping on the floor.

Even if the oil splatters due to the high-speed reciprocating motion, the splatters to the guide roller 23 side are received by the plurality of brushes 26, and the splattered oil also drips onto the guide oil pan 25.
Further, even if the mounting position of the bush support 16 on the cam lever 11 is changed, the displacement of the pull-down rope 12 does not change with the brush.
It has a length range of 26, and the oil wiping action by the brush 26 does not change.

Since the oil that travels from the rope to the oil catching member is guided into the cam box, the lubricating oil that travels down the rope moves to the oil catching member side by the catching action between the reciprocating rope and the oil catching member. It is possible to prevent the lubricating oil from being transmitted to the vicinity of the guide roller and dripping on the floor, which causes the opening failure or the rope breakage by returning to the box, and it is possible to suppress the waste of the lubricating oil.
