| -2- It is sometimes argued that any car electric clock should be arranged to stop off contact with the battery disconnected or run down to prevent the continuous heating of the windings. This renders the mechanism of the clock more complicated and also needs the human element to restart the clock. It appears at present to be a somewhat a matter of opinion as to which is right, some makers (e.g. Boyce) and experts favouring one method and others (e.g. Gent) the other. Gent. So far, the one sample Gent electric clock we have had recently (though we did have one previously which was unsatisfactory) has not operated satisfactorily on the bench and we are awaiting the makers for an improvement. Messrs. North & Sons. It is understood that Messrs. North have also in preparation an electric car clock for our experimental investigation. Seth Thomas. Though we have done a certain amount of experimenting with a Seth Thomas clock received from U.S.A. this is of little interest to us on the R.R. chassis. The clock has not been completely successful on chassis test. Generally, we are going ahead with the evolution of a satisfactory electric clock for the P.II chassis. EPC. | ||
