DRIVING IN THE RAIN

All kinds of preparations have been produced for rubbing on the screen in order to break up or prevent the deposit of- raindrops, but the trouble with most of these is the dust thrown up on to the windscreen from the wheels of passing ears, and the advantages of the preparation are consequently lost. When all is said and done, it would be .hard to find anything more efficient than a good mechanically operated screen-wiper, whether it derives its power from the suction existing in the induction pipe, from an electric motor or from the gearbox, as by a spedometer drive. It is, of course, necessary to set the rubber squeegee so that it will wipe, .off the rain without smearing it in semi-circular lines over the glass. The defect of some of the earlier types of suction-operated screen-wipers was that they often stopped when the throttle was opened. These devices, have, however, been much improved, with the result, that it is only when on full throttle, or -when accellerating violently on one of the lower gears, that the wiper momentarily stops working. So soon as the pressure on the accelerator pedal is released the arm immediately recommences its to-and-fro movement. Electrical windscreen wipers are, off course, unaffected by the engine speed. {
