Messrs. Aveling and Porter, of Rochester, showed a considerable number of engines, but their most noteworthy exhibit was the new steam roller which we illustrate at page 30. The gear is all carried in a box,so to speak, on the top of the engine, and instead of the conical rollers hitherto used in front. The great advantage of two cylindrical rollers has been secured by carrying the front end of the engine on a heavy cast iron fork, as shown. A pin reaches up from this fork and passes through a heavy casting above. There is sufficient play in this casting to allow the rollers to accommodate themselves to the shape of the read. We have already illustrated the drawing gear used with this type of engine.
