with a Draughtless Screen
IN our issue dated February 12th, we published an article dealing with a special form of windscreen devised by Mr. F. Assheton Taylor, Ersanmine, Kingswood Road, Tadwortb, Surrey. This screen is so arranged that it affords perfectly clear vision for the driver, who does not have to look through glass, and this without any draught affecting his eyes.
Several improvements have recently been made in this device, and it is now far less conspicuous and much neater than it was formerly ; also it can be manufactured at a comparatively low figure, this being between £7 and £9 for a type of screen which would tit, say, a Leyland Titan bus, in which, of course, forward control is provided.
The device is one which we consider ought to be givaral a fair trial, particularly on long-distance coaches travelling by night. Vision through a windscreen in inclement weather, however well the screen may be kept clear by a wiper, cannot possibly be so good as a direct view. It must always be remembered that an ordinary screen is purely a pro
tection against the weather, and not by any means an aid to clear vision.
The way in which the Clearsyte, as it is named, operates is to create a vacuum effect behind a sloping windscreen mounted slightly in front of a vertical screen ; the last-unused can he controlled to any desired height, so widening or narrowing the gap through
which the driver looks. Still farther behind and parallel with the sloping screen is a third glass panel, and the rush of air passes between the two and Out over the upper part of the car, a permanent space being left for this purpose whether the vehicle has a permanent roof or a hood. The outer of the sloping screens can, if required, be made of blue or some other dazzle-preventing glass.
Provisional protection has been obtained for the device, brit the period covered expires on October 1st, and the inventor requires a small amount of assistance befote that time to enable him to take out full protection and to develop the invention, which we think is well worth consideration.
