| only at 9-volts. Everything in fact in this Wiper from beginning to end is designed for loads far in excess of anything that the Wiper will ever be called upon to accept. FACIA FITTED : MECHANISM CONCEALED, PARKING KNOBS SHOWING ONLY. The Gear Boxes are constructed as separate units, the Main Box being connected to the Motor Unit by means of the very highest grade flexible shafting. The connection between each Gear Box Unit is by means of an adjustable highly tempered spring steel bar, the Boxes themselves being fitted into the Scuttle Rail and concealed by the Facia. Parking Knobs are provided and which enable the Squeegees to be parked below the Screen Frame, and thus out of vision, and when so parked are locked in position thus preventing the Squeegees from rattling on the Scuttle. SHOWING OUTSIDE OF SCREEN, WITH BLADES PARKED BELOW SCREEN. The Motor operates the Blades at a constant and even speed, and the Blades clean a very large area of the Screen, the whole mechanism operating inaudibly and smoothly. All outside Squeegee Fittings are heavily Chromium Plated and of very pleasing appearance, the Berkshire Patent Quick Release Squeegee Attachment enables the Scuttle to be cleaned without touching the Squeegees and thus possibly interfering with their setting. When ordering give dimensions between centre of spindles of gear box units, also length of flexible shafting required. The length of shafting should be as short as possible with a minimum number of curves, such curves it is recommended not to be less than 6in. in diameter.
