Bruce Hansen writes: There were three models shown in the manual using the TA conveyor belt added to the parts list in 1959. The first one is the Elevating Conveyor. Here are pictures in the up and down position. The belt is driven by a drum made from flanged wheels and a stack with a rubber band wrapped around the stack for friction. The conveyor is raised and lowered by hand.
The second model is called a Two-speed Universal Conveyor. This model has two belts which are connected through P48 mitre gears.
The third model is called the Straight Conveyor. It’s about 2 feet long.
