In the construction of the wheel hubs, the use of the “barrel” pattern, which has been for several years making its way, is more notable than ever, the old pattern with definite flanges thereon for the spokes, having nearly disappeared. This is in good part because the cup-adjustment bearing, which requires the barrel hub to go with it, has greatly gained ground, a large number of the leading makers having now adopted it for all, or nearly all bearings. Self-oiling devices and hollow axles containing oil and wick are also popular, the old projecting “lubricator” or cup for receiving oil, being wholly extinct. It is safe to say that this is an old device which reversion will never bring back.

The use of hubs having flanges, of a peculiar shape, made and drilled to receive the usual tangent spoke made straight from end to end without a hooked end to attach to the hub, is very largely on the increase, more than twenty of the leading makers now following that method. Spokes are still enlarged at both ends by the process of swaging or drawing down, instead of upsetting. Not a few makers are increasing their number, of course using a thinner wire.
