CHANGE SPEED LEVER WITHOUT TRIGGER FOR REVERSE Y3462 Acting on the decision arrived at at West WitteringHenry Royce's home town that as Springfield had abandoned the trigger for reverse on the change speed lever - we have sent out standardisation sheets for this to be adopted on the Derby cars. We have since however been running cars about with this trigger left off, and we consider it is a definite disadvantage to leave it off. We find, where we miss the trigger is when finding the 1st. and 2nd. gears. As regards the 3rd. and 4th., the gate forms a stop - as regards the reverse, the gate also forms a stop, but to find the 1st. and 2nd. there is no stop and the position of the lever has to be accurately judged in order to engage the gears. The only manner in which we think we could do with-out the reverse trigger, would be to make the normal position of the gear lever so that it was possible opposite the 1st. and 2nd. gear. We consider it unwise to drop the trigger on the change speed lever unless other modifications are made in order to enable the 1st. and 2nd. speeds to be easily engaged. We propose, therefore, cancelling the standardisation sheet for this modification. Hs.{Lord Ernest Hives - Chair} | ||
