We give above a side elevation of a fine engine exhibited at Hull, by Messrs. Aveling and Porter, of Rochester. The second engraving gives an end view showing the way in which the brackets for carrying the crank shaft is a very simple affair, and not being exposed to any violent strain it is, as a rule, durable. But with ploughing and traction engines the case is very different, the saddle is no longer simple but complex, and the strains to which it is exposed are so severe that great weight of metal is required to withstand them. Messrs. Aveling and Porter to get over this difficulty have introduced a very ingenious system of construction, which consists in carrying the side plates of the fire-box, and riveting to them, a cross plate carried over the boiler. The bearings are secured by bolts and cheek plates, as shown very plainly in the cross section. A filling piece is introduced at the point where the bracket rises from the boiler shell, for convenience in caulking, and no trouble whatever is experienced from leakage.
The arrangement is singularly elegant, and the weight saved very considerable. In the heaviest class of ploughing engines indeed, cast-iron brackets were long since abandoned by Messrs. Fowler in favour of steel, which is very expensive, and steel in its turn has now given way to wrought-iron. The general arrangement of the engine will be understood without further explanation from the engraving.
