| If there is one item on a Car which should be designed irrespective of cost, and manufactured as perfectly as possible, it is a Concealed Wiper; because, apart from the fact that it is a desirable feature of any Wiper, with concealed mechanism reliability is an essential, dismantling being no easy job should necessity arise, and roadside repairs most certainly can not be undertaken. The Houdaille Hydraulic Suspension Company, in addition to pioneering Hydraulic Shock Absorbers and adjustable Thermostats, were the first to introduce Electric Windscreen Wipers in this Country, their first models dating back to 1923, and from that date to this their Berkshire Electric Windscreen Wiper has earned and maintained an enviable reputation. Berkshire designers have since inception been carefully testing the different methods adopted for the concealing of Wipers (just as also have they noted the frequent changes in design, due doubtless to troubles with 'the various initial models which have been introduced). Gaining knowledge from the defects experienced with other types, we are now proud to offer the British Berkshire Remote Control Electric Wiper, which we honestly believe to be somewhat better in design, material and construction than any other Wiper on the market, and certainly stronger. The design naturally includes the latest methods of parking the Squeegees below the Screen, together with a Motor that can be placed in any position under the Bonnet or Scuttle. Casual comparison between the parts constituting the Berkshire Remote Control Wiper and any other Wiper on the market, will show that in every feature the Berkshire has a reserve of strength and power greater than any other. CRITICAL examination of these parts will furthermore show better design, material and workmanship. For instance the Armature in the Berkshire Motor has a 12 part Commutator against the usual 7 part, and the fitting of a 12 part Commutator ensures 100% perfect commutation. Substantial Ball Bearings are also used instead of the usual plain Bearings, so that the question of lubricating the motor becomes a negligible point. The insulation of the Windings is tested at 1,000 Volts, and particular attention has been given to the very robust die cast construction of the Motor Body. The Gears also are cut, not stamped. Uppermost in the Berkshire engineers' mind in designing and producing this Wiper has been the absolute necessity of long, efficient and trouble-free service, particularly bearing in mind that the removal for Service of any part of the actuating mechanism, being concealed behind the Facia Board, is a matter of considerable trouble, not to mention expense, and should therefore be avoided. The Motor Unit develops more than ample power to operate Twin Blades under the most adverse conditions, in fact the reserve is so great that amongst varied tests, made with this Motor was one with a 12-volt Motor, operating Twin Blades pressing tightly against a dry Screen, working however Manufactured up to a Standard — Not down to a Price | ||
