Accelerator lever for projectile looms

An accelerator lever for accelerating a projectile, the lever being driven by a shaft rotating in a direction about an axis, the lever comprising:

• a lever arm having first and second ends and at least two openings spaced apart in the direction of rotation;
• a clamping device having at least two apertures aligned with the openings, the clamping device being made in one piece and defining a clamping body having first and second arms extending about the shaft, the arms having ends each having at least one hole, and means, extending through the holes, for connecting the ends of the arms releasably to each other such that a releasable frictional connection is formed between the arms and the shaft;
• and
• fastening means for detachably connecting the first end of the lever arm to the clamping device, the fastening means extending through at least one of the apertures and at least one of the openings to form a positive, locking connection between the lever arm and the clamping device with respect to movement in the direction of rotation.

• a lever arm having first and second ends and at least two openings spaced apart in the direction of rotation;
• a clamping device having at least two apertures aligned with the openings comprising:
• a flanged bushing having a flange oriented perpendicular to the axis and a cylindrical portion oriented parallel to the axis, the apertures extending through the flange;
• a clamping ring disposed around the cylindrical portion;
• and
• detachable means for tightening the clamping ring around the cylindrical portion to form a releasable frictional connection between the cylindrical portion and the shaft;
• and
• fastening means for detachably connecting the first end of the lever arm to the clamping device, the fastening means extending through at least one of the apertures and at least one of the openings to form a positive, locking connection between the lever arm and the clamping device with respect to movement in the direction of rotation.
