A shaft that has two flexible joints then runs back to the instrument board and the actual operating handle just projects below the instrument board where it can be seen. The second suggestion is shewn on Fig 2 and is that a modified cock should be mounted on the dashboard and the cock removed from the induction pipe. A pipe is led from the float chamber to this cock on the dashboard and then from the cock to a union in the induction pipe. There is thus a long length of piping between the induction pipe and this cock, which is open to the former, but it is not considered that this would cause any trouble. There are three methods shewn of arranging the flexible shaft between the instrument board and the dash. Method X is to use a flexible joint similar to the present joint but with a little more end play, the Coachbuilders to cut off the shaft to a length to suit the instrument board. In order that this may not be left to the Coachbuilders it is suggested in Method Y a self-adjusting shaft might be used, and that two or three lengths of this shaft would cover the usual instrument board positions. In Method Z a castellated joint is shewn instead of the oblong driving key of Method one. In Fig 3 a suggested spherical bearing is shewn in place of that indicated in Fig I, the object of this latter being to cover all the angles of the instrument board with a single bearing. Contd. | ||
