Notes on a patent-protected air suspension system by Mons. Weyman, comparing it to conventional axle designs.

| some of its qualities in controllability, lack of steering shocks and freedom of pitching may be lost when increased wheel movement is given. Mons. Weyman was not too willing to give the secrets away, he says he is completely covered by patents so I will endeavour to return with complete drawings. It has 2 conventional axles, the suspension is on air. The front being connected to make rolling impossible, and the spring base raised to a large extent. The rear spring cylinders operate independently on the conventional rear axle. Although the air suspension is probably of no interest to us, it appears that a conventional front axle with a roll rod in front and raised spring bases, should not be overlooked. I hope Rm. {William Robotham - Chief Engineer} will be able to try the Ford if he comes over for the Salon. | ||
