THE hydraulic system is particularly applicable to portable riveting machines,and a number of these have been made of various designs, and for manyspecial purposes ; they are either direct-acting or constructed withsome form of jointed levers by which the dies are more conveniently ar-ranged for working in contracted places. The machines illustrated in the accom-pan3dng plates are of both types, and show only a few of the many different formswhich we make. The overreach, the width of the gap and form of suspensionbeing varied to suit the especial requirements of the work for which they are in-tended ; while the size and strength of parts are fixed by the total pressure re-quired, and the water pressure per square inch which
