The engine was built by Hawthorne & Com-pany, Leith, Scotland. It consists of two double-acting oscillating cylinders C C,placed at about right angles to each other, with piston-rodsE E, attached direct to a single crank D, of which the pin islong, with a gun-metal bearing. The cylinders are lined withbrass, and oscillate through a few degrees only, the oscillatingblock //being carried by two long bearing-pins /, which pass Fig. I. Fig. •5ij6«5lvifJ
