Abstract
The eccentric mechanism includes deflecting levers which are rotatably mounted on a fixed spindle and which bear against bearing elements in order to preclude an accumulation of tilting forces along the line of the levers. Each bearing element has a disc-shaped portion located between two levers and cooperates with a bushing, separate or integral, or a shaft portion to mount a lever.
Claims8
An eccentric mechanism for driving a plurality of heddle carrying frames in a weaving machine, said mechanism comprising
- a plurality of rotatable eccentrics;
- a plurality of cam follower levers, each said lever being positioned relative to a respective eccentric to be moved thereby;
- a fixedly mounted spindle;
- a plurality of deflecting levers rotatably mounted on said spindle, each said deflecting lever being pivotally connected to a respective cam follower lever;
- a plurality of bearing elements, each said element having an annular bushing portion and a flange portion disposed between a respective pair of adjacent deflecting levers;
- and
- means connected to each said deflecting lever to raise and lower a heddle carrying frame.
In combination,
- a plurality of heddle conveying frames;
- a plurality of frame actuating linkages, each linkage being connected to a respective frame;
- a plurality of movable eccentrics;
- a plurality of cam follower levers, each said lever being positioned relative to a respective eccentric to be moved thereby;
- a spindle;
- a plurality of deflecting levers rotatably mounted on said spindle, each said deflecting lever being pivotally connected to and between a respective cam follower lever and a respective actuating linkage;
- and
- a plurality of bearing elements, each said element having an annular bushing portion and a flange portion disposed between a respective pair of adjacent levers and about said spindle.
In an eccentric mechanism for driving a plurality of heddle carrying frames of a weaving machine, the combination of
- a spindle,
- a plurality of double-arm levers rotatably mounted on said spindle, and
- a plurality of bearing elements, each said element having an annular bushing portion and a flange portion disposed between a respective pair of adjacent levers.
