Rom H E Smith HDY.{William Hardy}1/HP.4.12.35. Isolated Gear Lever. Phantom 3. We send herewith N.Sch's 4694 and 4695 which show our design for the above. Owing to the change gear tower on the gearbox coming directly under the sliding seat rails we have had to incline the shaft and lower the face on the gearbox to avoid raising the front seats. As shown the maximum height of the gearbox is the same as now but without an inclined shaft the height would have been increased .750" with the same increase of seat height, as there is no spare space under the floorboards. The gate has been moved approximately 2.2" further from the centre line of the car to avoid interference between the gate and the seat cushion. The gate is now partly in the floorboards and partly in the body, and to reduce the interference with the body the bearings carrying the change lever are entirely on the inside as shown. The gate and bracket construction has been simplified. At the gearbox end the pendulum lever has bearings on both sides owing to the proximity of the cross. Incidentally an appreciable increase of efficiency of the actuation results. The selectors are altered in order to give more lateral tolerance between the pendulum lever and the selector. The side travel is increased from .50 to .55 and is still less than for the 20/25 and Bentley which have .60. Existing forgings may clean up for the modified pieces but in any case existing dies modify to the increased dimensions. We do not think that a gaiter need be provided over | ||
