Patent ID: 7516838

Claim:
A material conveying auger assembly of the type comprising a main drive shaft rotatable about a longitudinal axis thereof, a main flight section fixed to the shaft for rotation therewith to transfer material therealong, an intake flight section separate from the main flight section, said intake flight section comprising intake helical fighting secured to a tubular support sleeve rotatably mounted on an intake drive shaft portion which is adapted for connection to said main drive shaft so as to rotate therewith, and drive coupling means operatively interconnecting said tubular sleeve and said intake drive shaft portion, characterised in that: said drive coupling means comprises a radially displaceable detent movable between an engaged position with the intake drive shaft portion wherein the tubular sleeve and said intake drive shaft portion are drivingly interconnected so that the sleeve rotates with the drift shaft portion, and a disengaged position so as to disengage drive to the tubular sleeve, spring means biasing said radially displaceable detent in the direction of its said engaged position, said detent being housed in a detent housing secured to said tubular support sleeve, said housing having an open radially inner end.
