I was interested to read what you say in Hs{Lord Ernest Hives - Chair}6/KW5.2.34, and asked Cx{Major Len W. Cox - Advertising Manager} to look further into this matter and the following is what he reports in consequence. " We have to-day tried one of the Vauxhall cars with the Fisher scheme of ventilation, and we are not at all convinced that there is any case for the Fisher scheme as compared with the Quicktho scheme that we are proposing to try out on some of our cars. We cannot agree that with the Fisher scheme you can go along with all the windows open, adjust your deflectors and get no draught, at least that opinion was not borne out by our experience in the Vauxhall car to-day. We found that the angle of the deflector has a very important bearing on the amount of air admitted into the car, so much so that with the present cold weather it is not pleasant to have the deflectors open by more than about 20°, whereas they could be opened to approximately 45°. The following points in relation to each make an interesting comparison very greatly in favour of the Quicktho scheme :- Fisher Scheme. Full window aperture never available. Two separate controls. A centre upright frame divides the window in two sections. This is unsightly. This is American. We should have to pay royalty on this if we were ever granted the licence. We cannot supply this to customers now even if we wanted to as we have no licence. We understand the patent is not Quicktho Scheme. Whole window can be lowered. One control operates all movements. No centre frame need be employed. This is British. No royalty to pay. We anticipate that still further inventions improving on existing Schemes will shortly be available to the Public. | ||
