Abstract: A mounting system for mounting a truck toolbox in the rear compartment of a truck is provided that permits movement of the truck toolbox along the length of the side walls of the rear compartment is provided. The mounting system is installed for each of the side walls of the rear compartment. The mounting system includes: a rail disposed on the top of the side wall, a carriage that is connected to the truck tool box and which moves on the rails, and a pair of locking devices that when secured to the rail in abutting engagement of the carriage at either end thereof are operable to block the carriage from being removed from the rail. The blocking engage is achieved by an end portion defined by either end of the carriage overlapping with the locking devices when the locking devices are secured abutting, or in close proximity to, either end of the carriage. A truck toolbox is also provided that incorporates the carriage of the mounting system for mounting on the rail.

Abstract: A drive system suitable for a bicycle and capable of providing various drive ratios comprising first and second pairs of conical members, each pair including primary and secondary conical members, both of which are rotatable about a first or second transverse axis. The conical members each comprise a series of evenly spaced sectors with the sectors of the primary conical member being slidable between the sectors of the secondary conical member in each pair. There is a first shaft for rotating the first pair of conical members. The primary conical member of the first pair is slidably mounted on the first shaft. The secondary conical member of the first pair is fixedly mounted on the first shaft . The conical members of the second pair are mounted on a second shaft. The secondary conical member of the second pair is mounted for axial sliding movement relative to the primary conical member. A continuous V-shaped drive belt extends about both pairs of conical members.
