| contd :- -2- In the case of the front axle, we suggest it might consist of : (1) A flexible pipe from a junction on the main system on the frame to a connection in the end of the shock damper rocking spindle. In [handwritten: the] case of the S.S. this has rotational movement of 26°. (2) The present oil-way (rigid) down the damper lever to be utilised for pressure feed to a connection in the screwed end of the ball end. This connection might take the form of a double drip plug, as the drip plug in the shock damper casing would be eliminated. (3) Either (a) a flexible lead direct to the axle from a connection in the ball end, or (b) a flexible lead to a connection on the anchorage triangle or tube and thence by a rigid pipe in this member to a further connection at the bottom end. A short flexible connection from this connection would couple it up to the main conduit in the axle channel. The rear axle could be treated in a similar manner. A further function of central oiling is to deal instantaneously with the demand of a bearing and we feel that correct steering, being dependent on adequate lubrication of the pivots and steering tube ball ends, it would be advisable to be able to deal with any stiffening up at once, by depressing the pump pedal. Such contingencies are met with considerable inconvenience at present. We think the Bijur pump capacity would have to be increased for this purpose, as the whole 40 contd :- | ||
