| - 2 - with their fitting and also the consequent central lubrication points. The one point where they are unsatisfactory is that too much pedal pressure is required on big cars. If this system was coupled with a servo such as ours we believe that it would be as satisfactory as anything that could be devised. Bonnet Ventilators. The Graham Paige have developed a bonnet ventilating shutter arrangement which is neat and should be free from rattles. A Torsional coil spring is fitted in the door hinge which tends to keep the door permanently open. When the door is pushed flush with the bonnet side a spring loaded catch operates and holds it closed. To open the spring loaded catch A.{Mr Adams} is pressed with the thumb when the shutter flies open. The advantage of this spring compared with the toggling arrangement appear to be - (1) Operating knob can be so small as to be hardly noticeable. (2) When closed, held with full spring pressure. Its disadvantage is that it is not so simple as the straight toggling scheme. TORSIONAL SPRING TRYING TO KEEP SHUTTERS OPEN. A Shock Dampers. We note that the tendency is to fit the shock absorbers | ||
