all of the meshing gears being supported by a pair of parallel shafts, one being the input shaft and the other the output shaft, there being no countershaft involved

Full Title

Toothed gearings for conveying rotary motion with variable gear ratio or for reversing rotary motion (speed-changing or reversing mechanisms F16H59/00 - F16H63/00) > without gears having orbital motion > exclusively or essentially with continuously meshing gears, that can be disengaged from their shafts > characterised by the disposition of the gears (F16H3/083, F16H3/085 take precedence) > all of the meshing gears being supported by a pair of parallel shafts, one being the input shaft and the other the output shaft, there being no countershaft involved
