Abstract
This specification describes a multiple throw selector apparatus for use in change speed gearing which includes speed ratio shift rails to engage synchronized clutches and a range lever which engages an unsynchronized clutch. The range shift rail is moved between its various operative positions directly by a selector member. The ratio shift rails are actuated by the selector member through a pivoted link thereby increasing mechanism advantage between control lever and ratio shift rails.
