Abstract
A coaxial drive shaft system is provided with an overload shearable coupling for driving multiple outputs from a single input. A pair of coaxial, telescoped drive shafts are provided as independent outputs to a pair of driven devices. A singular input shaft is coupled to the drive shafts by a gearbox for simultaneously rotating the drive shafts. A shear section is formed in one of the drive shafts for rupturing the one drive shaft in response to an overload condition thereon, while the other coaxial, telescoped drive shaft continues to be rotated by the singular input shaft.
