X.295 X.3923 X.3762 As a result of the fitting of two Smith type 2D dynamos on the two experimental cars 6 EX and 49-GB and the good results, in respect of small miles per hour, for cutting in and output observed by Mr. Hives, it was considered desirable to interview Messrs. Smith's representative as to the possibility of their supplying us with suitable switchboard for use with the Smith dynamo on the car. With this end in view we received a visit from Mr. Lock of Messrs. Smiths on Thursday afternoon, in order to discuss this question. Mr. Lock brought along with him another sample of their bezel operated switch, but it was agreed and explained to Mr. Lock that this particulars switch was not the type of thing we should require. After some discussion, during most of which it seemed that there was no easy way out of the difficulty, as it was not considered feasible (from a policy point of view) to fit Smith dynamos to the cars to operate with the present Lucas switchbox, (This would be electrically quite possible, but would not secure the advantage of the use of the Smith cut-out which, although bulky, has, so far as Contd. | ||
