Abstract

The declutching gear has a locking lever (22) which is hinged and acts as a stop (20) for reverse running. This is joined by a rod (19) to the centre of a bar (17). The declutching control is a lever (28) and another bar (12). These pivot simultaneously in the same sense as both bars. There is also an arm (16) which gives unlocking of the two jaw blocks. Positive action of the lever (22) is given by its engagement with an elongation (25) of the traction organ (6) sliding in an opening (1) of the gear. This can only be done when there is no load on the cable (4).
