| 2819 Rm{William Robotham - Chief Engineer} To Mr...........From Mr Copy to Mr. W.O.S. U.V. Hs.{Lord Ernest Hives - Chair} Gr.{George Ratcliffe} Tn. A.{Mr Adams} re:- Body Ventilation. (1) THE FISHER SCHEME (GENERAL MOTORS). Two objections which have been raised to this scheme are that two handles per window are needed and that a permanent division is necessary in the form of a plated channel down each window. Both window and ventilator can be operated independently, which I suggest is a great point. (2) QUICKTHRO. In this Scheme the deflector glass can only be operated when the window is closed, but on dropping the window, the deflector pane goes down also. There is only one handle to operate. This appeals to some people because the metal vertical channel is not visible under this circumstance. I suggest that this Scheme is not so effective as (1) because one cannot have all the various combinations of window and deflector settings. (3) NEW QUICKTHRO. An advance model of this was seen on Wednesday. There is one control handle. The scheme is similar to (2) with the exception that the deflector can be operated both with the window closed and with the window down about 3 ins., and also when right down. However, the window only goes down, so that the scheme has the same objection as (1) (4) ESSEX SCHEME. This is seen on the Terraplane. I dismantled a door and have made the attached photographs and sketches of the mechanism. The vertical dividing channel and the deflector pane are one. -1- | ||
