Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Handwritten Note: +200/5 E/EV.{Ivan Evernden - coachwork}2/MN.18.4.35. Wyman Have a look at this before it goes away on CBW BENTLEY Independently Mounted Wings and Radiator. We are sending you herewith LeC.4409, LeC.4467 and LeC.4473 showing a revised design for the independently mounted front wings and apron on the Bentley. Advance prints of these have been handed to RHC.{R. H. Coverley - Production Engineer}, as we understand it is anxiously desired to get these features on a chassis waiting to go to the Coachbuilders. On LeC.4409 we show a revised bonnet valance strip with easy attachments both at the front and rear. The positions of the bonnet catches vertically have been altered, and this will entail a modification to the lengths of the louvres in the front of the bonnet. The covers over the dumb irons are carried as extensions from the bonnet balance strip, and these in their turn carry the front apron. When the chassis is delivered a strip of aluminium will be inserted in/position to be occupied by the wings / the so that the dumb iron covers that meet them may be bolted up in their correct position. The clearances around the brackets for the front horns, etc. which pass through the apron will have to be increased to at least .312". The foot of the revised design of wing stay is shown, but a complete detail of the wing stay is shown on LeC 4467. On this drawing also, we show a spherical wing support modelled on the lines already sent to you for SpectreCodename for Phantom III. We have modified the attachment of the bracket to the radiator yoke to make this joint detachable, because detachability is necessary to enable the wings to be removed. We have also hidden the fixings to the yoke behind the radiator shell. On LeC.4473 we have shown a small spring steel bracket coming from underneath the front of the radiator to steady the apron in position transversely and to hold it in its correct position in a horizontal plane. This is found necessary to correctly position the apron whilst the dumb iron covers and front wings are being erected. Ev.{Ivan Evernden - coachwork} | ||
