Jordan Spreader front view (taken in 2004 at the beginning of the Friends restoration. The flanger blade(s) is below the coupler and raised/lowered by the cylinder above the coupler.
.
Two views of the operator's air valve control stand before the operator's house was completely removed.
Valve functions top to bottom: Left and right main side blades raise and lower (large cylinders inside the house), left and right side blades extend /retract (two medium size cylinders between house and air reservoir), at the bottom is the valve to raise and lower the front flanger bade (square shank, handle is missing).
The two top 3-way valves are for the side blade extend/retract:
After the wooden operator's house was removed showing some of the air piping for the various blade functions. Also the control valve "tree" is visible.
Also, at last report (September 2018), efforts to make the air reservoir usable have not been successful due to severe corrosion around the inspection port that defies efforts to seal it. This would mean that an independent compressed air source would most likely be required to operate the Jordan. Engine air alone is/or hasn't been sufficient, the air pumps just can't provide enough wind to move eveything. That information was from Terry Rider who worked on the Jordan during this year's work sessions.
