Herewith we send M. {Mr Moon / Mr Moore} sch. 3356. showing a modification to the jaw clutches in the revised epicyclic 3rd. speed gearbox. The modified jaws shown are those between the 2nd. and 3rd. speed, but they are also applicable with very slight variations to the jaws for the top and 3rd. speeds. It is not intended that this modification should apply to any pieces you have already made or are well advanced for the trial epicyclic train. DA. {Bernard Day - Chassis Design} | ||
