A mobile carriage system includes a pair of end rails (12a, 12c) fixed to a support surface and one or more intermediate rails (12b) located parallel to and between the pair of end rails (12a, 12c). At least one carriage (10) is supported for movement on the end and intermediate rails (12a-c). The carriage (10) includes an elongated frame (17) that spans all of the rails. At least two drive units, each including a pair of wheels (23) and supporting the carriage on a different one of the rails are provided. The drive units are operatively connected to a drive shaft (35) which extends across a plurality of the rails. The drive shaft (35) and each of the drive units are coupled by a drive gear (33) on the shaft which has a substantially smaller diameter than the diameter of driven gears (29) on the units. An electric motor (41) is operatively connected to the drive shaft (35).       Recently Added Patents Methods and apparatus for low power out-of-band communications Churn prediction and management system Semiconductor overlapped PN structure and manufacturing method thereof Maize variety hybrid X03A157 Coordinated garbage collection for raid array of solid state disks Aqueous composition with agents to inhibit water evaporation Permanent magnet rotor with flux concentrating pole pieces   Randomly Featured Patents Drive belt cooling system for small vehicle Displacement unit Fluid catalytic cracking of hydrocarbons Message filtering method Mechanical wrist mechanism Method of generating an interpolation image, an interpolation image generating apparatus, and an image display system using the same Wheel rim Tandem type rod end Compressed-air pile-driver Semiconductor memory having predecoder control of spare column select lines © 2006-2008 PatentGenius.
