Abstract

23,945. Roots, J. D. Oct. 19. Controlling-apparatus, arrangements of transmission gear in conjunction with.-In a variable-speed friction driving-gear for use on a motor-vehicle, a belt pulley A forms also a friction wheel in contact with a pair of driving- disks B<1>, B<2>. The wheel A is mounted on a lever P by means of which it can be traversed across the disks B<1>, B<2> to vary the speed. The front part P<Î> of the lever has a pivot Q and is arranged to separate the disks B<1>, B<2>, when depressed, before the lever is moved as a whole. For this purpose, the disks are connected by two screw-threaded sleeves T, T' rotated by links Q<1>, Q<2> pivoted to an arm Q<3> of the lever P<Î>.
