(3) He does not consider that there is any increased difficulty in making sound connections on 6 volts, and that the increased weight of the cables is insignificant. (4) As referred to again below, the vibrator voltage control system, which is the best method, is very much more satisfactory on a 6 volt system than on a 12 volt. Mr. Bijur believes in a few years time, all car lighting and starting systems will be for 6 volts. He stated that in America, the Dodge and Maxwell are the only firms still sending out cars with 12 volt systems, and that Dodge are in process of changing over, leaving the Maxwell only on 12 volts. In France, he stated that those who are already on 12 volts are gradually changing over. He thought that we should be prepared in case we also had to change at some future time. Mr. Bijur stated that he would, if convenient to us, arrange to get hold of a Marmon car in London, this being equipped with Bijur apparatus, and that we should pay a visit in the near future to inspect this and particularly to watch the operation of the Bijur pinion engagement mechanism which he states to be very silent in action. We left it with Mr. Bijur that one or two of us would be quite prepared to pay such a visit. Contd. | ||
