| - 2 - A further reinforcement of the body structure can be achieved if the front door is made to act as a diagonal bracing between the scuttle at the screen pillar and the rearmost portion of the body at the centre pillar. This calls for strong hinges attached by bolts to the centre pillar, and for some form of lock other than the orthodox bolt lock. The lock must hold the door shut face to the pillar in all directions and may take the form of a Silent Travel type lock, at the waist rail, or a double lock at the waist rail and the base of the pillar. In the case of the Sedanca and other bodies with a de Ville extension, it has been found expedient to cause thedemountable cantrails, whether they be folding or sliding, to act as a tie between the top of the screen pillar and the top of the centre pillar. When the head is closed the cantrail must be fixed by some form of rigid attachment at both of its ends. The mounting of this type of body calls for a special treatment. Whereas in the case of the totally enclosed body the attachment of the scuttle to the dash board and the frame is made semi-flexible, it has been found that in the case of bodies with demountable tops it is beneficial to make this attachment solid. No attendant disadvantages will result. On sheet 6 we show the method of making this attachment. The scuttle attachment at the top is made rigid by the use of a special aluminium packing between the body and the dash board, see sheet 6, Fig."I". Likewise the side scuttle attachment is rendered solid by the use of an aluminium block in place of a rubber one, see sheet 6, section "m". The scuttle to frame attachment at the scuttle base consists of a solid bolting with an aluminium packing to replace the rubber, see sheet 6, Fig."a". All of these special parts can be obtained by application to Messrs.Rolls-Royce Ltd. The body mounting on the chassis body brackets is the same as that for the fixed head closed bodies as shown on sheet 1., which instructions should be rigidly adhered to. Experiments have proved that this rigid attachment of the scuttle to the dash board and the frame has added increased rigidity to the front of the body in the case of the Sedanca and all other types of body having a demountable front cantrail such as the Cabriolet, Drop Head Coupe, and All-weather. | ||
