Abstract: A tubular telescoping drive shaft for transmitting rotation from a rotating power source to an element to be rotated thereby, including at least one inner member or shaft telescopically receivable in an outer tubular shaft and including a universal joint such as a Hooke's joint having pivotal yokes connected with a cross link, all of which are at least substantially received within the outer tubular shaft in a fully retracted position and are rotatably pivotable therein for accommodating misalignment of the rotating power source and element rotated thereby.

Abstract: A multi-rotor blower fan assembly for a cotton picker utilizes a plurality of separate fan enclosures each containing a fan for supplying an individual air flow to a picker unit of the picker, the fans being mounted on a common shaft for rotation therewith, with a unitary removable or openable cover or hood covering access openings of the fan enclosures. One or more of the fan assemblies can be mounted on the picker, for instance, on an existing platform on the picker chassis just rearward of the operator cab, in end-to-end relation, and rotatably driven using a common drive.
