Abstract

A mechanically operable clutch having a foot pedal used in connection with a transmission operated by a lever is arranged with an operating assembly physically connecting the clutch pedal to the clutch. The operating assembly includes a pair of pistons, one within the other having a lost motion connection including a compression spring between them. The inner piston being connected to the pedal and the outer piston to the clutch. The pistons form a chamber between them normally open to the atmosphere. A source of vacuum and a valve controlled by the transmission lever and operable when said lever is moved to place the transmission in neutral to connect the chamber to the vacuum source and thereby shift the pistons in such a way as to hold the clutch disengaged and the pedal erected so long as the transmission remains in neutral.
