Since some of our readers collect and restore road rollers, we present this information from a book, 'New Catechism of the Steam Engine,' M. E., published by Theo Audel & Co. in 1897 and 1904.

The steam road roller may be classed among portable engines.

It is built in various sizes, and can be used for rolling down highways, breaking up old roads, plowing and hauling heavy loads, etc.

Some road rollers have a boiler of the locomotive type; on these styles, the engine being a horizontal one, is placed on top of the boiler, and connected to the driving wheels or back rollers by means of sprockets and chain, or gear wheels.

In these rollers the boiler forms the principal part of the frame; the front of it, which forms the smoke box, as in the locomotive, is built out into 'the goose neck,' to which is swiveled the yoke by means of the king bolt.

The yoke being able to swing, rests upon the axle of the front roller, which also forms the steering wheel. The horizontal swinging motion is imparted to it by the steering mechanism, which consists of chain and worm gear, and is operated by a hand-wheel near the reversing lever. Figure 1 shows a roller of this type, which is built by the Harrisburg Car Mfg. Company of Harrisburg, Pennsylvania.
