| (2) re-enforced with the bandage triangulation introduced by Pomeroy, torch welded to the edges of the channel section, from where the cruciform member finishes to each end of the frame, but not on the length straddled by the cruciform. Some of the metal work of the crossmembers is of thicker gauge than the side channels, approximately .1" thick. With regard to body mounting brackets, Daimlers have departed from the scheme they have on their previous straight '8' chassis, and now only provide comparatively simple and few brackets rivetted to the side channels. Owing however to the diaphragm effect of such brackets carried on the web of the frame they have been compelled to add re-enforcements, in one case a sheet metal tie to the top of the frame, and in another the addition of a sheet metal box provides the necessary stiffening. The radiator lamps, wings, and front apron are carried on a single sheet metal crossmember at the front, mounted on a central pad of rubber, and there is a broad sheet metal lug on the rear of the radiator at the top, obviously intended as a means of staying this front structure from the dashboard or bodywork. No dashboard, however, is provided and so far as Park Ward's are aware they are expected to build this up with the bodywork, providing a tool box and plating same with aluminium to instructions provided by Daimlers. We anticipate obtaining further particulars of this. The front mudguards are provided with the chassis and are made in pressed steel from dies. The rear ends of these mudguards are carried by single stays to the frame and are very flexible owing to the diaphragming effect of the thin frame web. The rear axle is a normal undertype worm and it is noticeable that Daimlers now arrange to take the worm wheel away through a large hole covered by a flange carrying one of the axle tubes. This was originally taken away through a large cover plate carrying the worm, and which constituted a very weak feature. The front axle is of the conventional type but is controlled by a parallelogram on each side of the frame, linkage | ||
