Experience has shown wood wheels of this sortto be cheap and durable for all heavy work. Thewheel is driven through a detachable outer hub platemade in two halves (H and H, Fig. 5). These halveshave lugs, L and L, which are assembled around onefork of the universal joint, the other part, U, of whichis seen in Fig. 3. H and H are bolted together and tothe outer hut binding ring, R. A light hub cap, the hub. In the new model the brake bands.

It demon-strated the theory that a machine driving all fourwheels independently will not slip itswheels, and will be able to travelthrough roads impossible to negotiateby a two-wheel drive, although itstires are neither corrugated, spiked,nor roped in any way, nor have theyany special anti-slip device of anykind. The machine shown will carry fivetons. But while this machine is achain-driven machine, the 1905 model,which is now being gotten out, willhave a bevel gear drive throughout,the chain drive being superseded bythis type of drive except for exceed-ingly heavy trucks. The theory that the additional ma-chinery
