The guides of the pile-driving machine must be set to the batter at which it is intended that the piles are to be driven. The easiest way to do this with a machine having upright guides will be either to shorten the back raking shores or else to set them farther back at the foot, if the sills are long enough to allow of this being done. The piles will most likely require guiding by walings placed one row near the top and another row as low down as possible, as shown in Fig. 1. Sometimes a hinged joint is provided at the head of the piling machine after the fashion indicated in Fig. 2, where wrought-iron straps are shown bolted to the guides and shores, hingeing on a spindle that serves to carry the pulley. By this arrangement the machine may be set for driving vertically or at any required batter.
