A Pressed Sleel Construction having many Good Features.
Mr. P. A. Fisker, of Copenhagen, has undoubtedly gone a long way towards achieving the embodiment of the ideas of super-refinement enthusiasts in his patented motor cycle design here illustrated.
The principal features of the construction are the duplex pressed steel members carrying file engine and connecting the steering head and the rear wheel stays. The saddle is supportfid by the steel tank, which is attached to the steering head at one end, and the main frame plates at the otlier. The springing is of a decidedly novel type, comprising long lever arms and helical springs. The extra saddle, which is fitted in place of the more usueal carrier, is also sprung.
A great deal of attention has been paid to mudguarding. The pressed members are stiffened laterally by wide footplates extending the whole length of the engine. The engine rests on another plate, which forms an undershield, so that it is practically enclosed in a mudproof cradle. A four-cylinder engine is shown fitted with a simple type of totally-enclosed shaft and bevel drive.
No indication is given in the specification of any further provision of means tor the prevention of lateral play in the springing of either wheel. Failing any additional support, to that shown at these points, we should expect the side movement to be considerable.
The frame construction, however, as a principle, has much to recommend it.
