that Mr. Hill used the compensating gear among his steam carriage improvements, a device invented by Mr. Richard Roberts, of Manchester.

One of the difficulties attending the construction of steam carriages was the connection of the driving wheels with the machinery, so as to obtain the full adhesion of the wheels, and at the same time to allow facility in turning sharp corners. James, as we have noticed, fixed each driving wheel upon a separate axle. Hancock and others employed only three wheels in their carriages, and applied the power to the front wheel, which ran in advance of and between the tracks

of the other two. The most common plan, however, was to have only one wheel keyed to the driving axle, while the other was connected when required by a sliding clutch, which was anything but a convenient arrangement. Rut in the patent compensating gear used by Roberts, Hill and others, shown in Fig. 50, all these objectionable plans were obviated ; and this simple and efficient gearing, introduced sixty years ago, is in regular use on every road engine built at the present time.* Upon examining the illustration it will be seen that so long as the driving wheels continue to run in a
