| TO BX. FROM DA.{Bernard Day - Chassis Design} (Struck through) Copy to - CL. HS.{Lord Ernest Hives - Chair} ORIGINAL (Stamp) DA{Bernard Day - Chassis Design}1/M28/8/24. GOSHAWK 111. FRONT AXLE. V5920 We send herewith N. scheme 1839., shewing the front axle with brakes for the revised Goshawk. Roller bearings are shewn both top and bottom of the pivot and we should like to try these, but in the event of the lower one not being entirely satisfactory we have given you an alternative in the form of a plain bearing. It is intended that this axle shall be controlled by the top plate of the spring and a lower radius rod. The exact position of the radius rod will be determined later, and this also applies to the exact position of the inside lever on the brake shaft, which has to be lined up with the differential mechanism. We have shewn the new type of locking device on the Dunlop wheels so that the same pieces can be used for both wire and steel artillery wheels. We should be glad if Derby would check out the various clearances at an early stage in the proceedings so that we may effect any alterations that may be found necessary. With reference to the pull off spring on the brake shaft we have shewn a certain length of wire which makes a moderate sized spring. If found too stiff there is plenty of room to lengthen it, or if the square wire is not made in SWG. gauges, there can be a re-adjustment of the stress. DA.{Bernard Day - Chassis Design} | ||
