Patent ID: 7997208

Claim:
Angle line transfer apparatus for an overhead conveyor comprising: first and second generally horizontally extending, side-by-side load tracks for receiving load-bearing trolleys for movement along said first track and for movement along said second track, a first transfer shuttle unit having a normal position aligned with said first track at a first transfer location and providing a continuation thereof, and a transfer position aligned with said second track at said first transfer location to provide a continuation of said second track, a second transfer shuttle unit having a normal position aligned with said second track at a second transfer location spaced along said conveyor from said first transfer shuttle unit and providing a continuation of said second track, and a transfer position aligned with said first track at said second transfer location to provide a continuation of said first track, a first actuator connected with said first shuttle unit for shifting the unit between said normal and transfer positions thereof at an acute angle to said first track, whereby to transfer trolleys on said first track to a position aligned with said second track for movement along said second track, and a second actuator connected with said second shuttle unit for shifting the second unit between said normal and transfer positions thereof at an acute angle to said second track, whereby to transfer trolleys on said second track to a position aligned with said first track for movement along said first track.
