| To DA.{Bernard Day - Chassis Design} from R.{Sir Henry Royce} -2- E10/G21/8/19 Contd. dispense with the nut which at present performs the double duty of securing the ball and acting as the body of the greaser. The screwed stem of the ball itself should be made longer for carrying the greaser, while the ball should be secured by a plain nut locked by a pin. (7) Referring to the bottom ball joint, the square head of the adjusting screw should be replaced by a hexagon which will be neater and smaller. (8) To provide a further precaution against the entering of water into the shock absorber, the outer bearing bush should be made with a recess for a washer, so that when the bearing at this point is slack, the washer will follow the movement of the shaft and act as a bar to any water which may attempt to run in. (9) Referring to the lubricator on the shaft of the shock absorber itself, the hexagon for screwing this piece up is considered not sufficiently bold, and should be made about 50% wider. (10) Referring to the split pin which serves to maintain the inner portion of the connecting link in its correct rotational position, it is noted that drawing No. Lec.1077 shews the slot in the inner piece in one view section CC, and the slot in the outer piece in another view section DD. The model has been made with a slot in the inner piece, and this should be adhered to. (11) The biting-in bolt of the lever should be transferred to a corresponding position on the underside of the boss. With the bolt on the upper side there appears to be the danger of water collecting in the split of the lever on the inside, and running into the front bearing of the shock absorber. (12) The facing for the spring washer on the boss for the biting-in bolt is not large enough, and the spring washer jams. This facing should be suitably increased in diameter. (13) Referring to the inner member of the connecting link, the ball sockets on each end, as mentioned above, should be made in bronze. This piece seems to be very heavy, and should be reduced in weight. The sockets for the tube should be made much shorter, and one of the taper pins in each socket cancelled. On the model the stem appears to have been turned from bar, and two collars have apparently been formed (Contd.) | ||
