Constructional Particulars oi a German Maker's Latest Model.

In our issue for the 14th September, 1911, we reproduced a photograph of a novel design of petrolengined road roller, which had at, t hat time just been produced by the Milan firm of Gola and Conelli, an undertaking with which is entrusted the representation of Aveling and Porter, Ltd., in Italy. Whilst the constructional features of this workmanlike machine have not been varied other than in detail, we are interested to receive particulars of the latest model of this type from one of our Continental correspondents. He forwards a general-arrangement drawing of the latest type of machine, and as this reveals the form of construction in a very clear manner we have reproduced it herewith.

It will be seen that a four-cylinder engine, which develops about 30 h.p., drives through a clutch on to a cross shaft, and thence by way of a two-speed gear to a lay shaft, which carries the single chain sprocket for the final drive to the near roller. The company makes two types, of six and eight tons gross weight.

An unusual feature of this latest machine is the arrangement which has been made for the heating of the rollers. On the model which we have under consideration, the front roller is arranged to hold a coke fire. whilst the rear roller has provision for heating by means of the exhaust from the engine. The disposition of the piping for this latter arrangement is evident from the illustration herewith.

It is of interest to note that Barford and Perkins, Ltd., the wellknown Peterborough manufacturer of many handy internal-combustion driven rollers, some three or four years ago made certain sue

cessful experiments in the way of heating the hind rollers of its standard models. We are advised, however, that there has been not much demand for this modification, and that therefore Barford and Perkins, Ltd., has not developed the idea to any extent.
