N.Sch.4776 is satisfactory with flexible engine mountings, but it will cost £1.12.6 per car more than the present standard arrangement. We think the most expensive part of the scheme is the horizontal link from the pedal shaft to the engine, with its ball ends, and suggest that the following simplified scheme would be just as effective and cost much less:- (1) Anchor the pedal shaft rigidly to the frame thus cutting out the ball joints. The fore and aft movement of the engine would then have to be controlled by a link as on the 25/30. The simple bronze bushes used on the 25/30 link may not be adequate to cope with the increased torsional movement of the engine, but this point would have to be determined experimentally. (2) Replace the diagonal links to the frame by a simple flat strip. This would be much cheaper than the present tubular piece with forged knuckle pieces pegged and sweated on. (3) Possibly replace the operating link from the pedal stem to the intermediate lever by a chain, á la{L. A. Archer} Chevrolet. This will cope with engine movements, and be cheaper than the present piece with its two spherical bushes. Rm{William Robotham - Chief Engineer}/Smth. | ||
