GEARBOX. -------------------- Herewith we send N.sch. 3354. shewing some modi- fications requested by the Expl. Dept. (1) The two diameters on the 3rd. motion shaft prevent the bearing jamming the gear. Advantage has been taken of this to run the serrations under the ball bearing. Will Derby please say if this presents any difficulty? (2) A method of fixing the cones to the sliding piece by means of countersunk screws without slots in the head. (3) Drilled rivets for holding the cone to the constant mesh wheel. DA.{Bernard Day - Chassis Design} | ||
