| Translation of letter received from Mr. A.{Mr Adams} Renaudin, Consulting Engineer, 33, rue Alex Dumas, PARIS. Dear Sirs, I am taking the liberty of informing you that I have at my disposal a patent concerning a new steering mechanism, worked by hydraulic power (oil, grease). The following summary will give you the chief points in the advantages obtained by the invention :- 1. The pivoting motion of the front wheels cannot effect the steering adjustment (as all the necessary forces for swivelling the front wheels are taken up by the front axle itself.) 2. Factors, such as reduction ratio and coefficient of irreversibility, are independent of oneanother, can be given any desired value, e.g. from total irreversibility to any given coefficient. 3. The system does away with the usual steering mechanism, and hence with all its defects and shortcomings. [handwritten: g is] 4. Higher efficiency, greater elasticity and absence of play. 5. Absolute safety. The danger of breakage of parts is replaced by the risk of leakage, which is never instantaneous. 6. The cross steering tube, being dispensed with, the connection between the two front wheels is not rigid. [handwritten: ??? fs{F. Steele}] 7. Lower manufacturing costs. This steering gear can be fitted to any chassis, without modifications, as the existing steering levers can be utilized to work the front wheels. The system has been noted as an interesting one by the National Office of Inventions, and also by certain Motor Car engineering authorities. Etc. Etc. | ||
