In response to In response to 3


  

          

This was an "improvement" in the original design, if that it added more weight to the door while lowering the overall height of the entire mechanism. The designer go the bright idea of making the piston and rod stationary, instead of the cylinder. Had this design been used on the Olympic-class, there would have been no need for the overhead recess which ran to the underside of G-Deck, need to house the two hydraulic cylinders ("cataracts") which regulated the closing of these doors. Of course, the ultimate improvement was the electric motor-driven version of these doors, first installed aboard RMS Arundel Castle H&W No.455, and then quietly retrofitted post war into the Olympic. (Personally, I believe that these retrofits were recognition by H&W that, in certain circumstances such as severe a racking motion to the hull -- i.e. Britannic -- there was the possibility of the doors being rendered inoperative by gravity alone.)
