The slotted tail portion of a sector gear has slideably mounted thereon a substantially U-shaped clamp with one end of the clamp having a bent lip so that the clamp has a cross-section substantially conforming to the cross-section of the tail member. A screw passes through an opening in one leg portion of the clamp, through the slot and is threaded into an opening in the other leg portion. The screw may pass through a link and can be loosened with respect to the clamp to permit positioning of the clamp along the slotted tail portion without separating the screw from the clamp.
