This document describes various mechanisms for picking in shuttle looms. It defines picking as the process of passing a pick of weft between the upper and lower lines of a divided warp to build half of the cloth. It classifies picking mechanisms as shuttle, negative, or positive picking and lists types of overpick and underpick mechanisms like cone overpick, side lever underpick, and side shaft underpick mechanisms. Diagrams and labels are provided to illustrate the components and functioning of the cone underpick, side lever underpick, and side shaft underpick mechanisms. The document also defines normal, early, and late picking in relation to the timing of the shuttle leaving the shuttle box in relation to the bottom center position of the loom.
