Original Directions for Operating
Dunbar Popcorn Wagons
ADDENDUM TO DIRECTIONS FOR OPERATING
by
Bruce Wm. Anderson
Links to White gas systems valves will be added shortly
This is the best information we have been able to collective as of 2013 - Please do your own research and operate at your own risk using common sense.
To Prepare The Popcorn Wagon for Operation:
Water tank should be 2/3 full of water
Boiler should be 2/3 full of water
Boiler Water Level: never less than 1/2 inch in water site glass – never more than 1/2 inch from the top of the water site glass
Gas Vapor Generator drip cup must burn for 3 min. to preheat the Gas Vapor Generator
The steam engine must be allowed to continue to run after extinguishing the boiler burner flame so that the steam is removed from the boiler. This will prevent siphoning water from the water tank to the boiler due to a vacuum being created in the boiler as the steam cools and changes to water.
Fill the peanut roaster two thirds full and roast for approximately 50 minutes. Check with peanut tester to determine when roasted properly.

All valves were identified by brass tags attached to the valve handles with string. These tags were stamped with the identifying number which corresponds to the following numbers.
All shift levers were identified by paper labels attached with string when the popcorn wagon was new?
No. 1) Valve: Gas vapor and liquid gas valve for filling the drip cup on the gas vapor generator and for regulating gas vapor generator burner. Valve located on the gas vapor generator.
No. 2) Valve: Gas vapor valve for boiler burner. Valve is located on the gas vapor generator.
No. 3) Valve: Gas vapor valve for peanut roaster. Valve is located on the gas vapor generator.
No. 4) Valve: Gas vapor valve(s) for popper(s). 1 or 2 valves are present depending on the number of poppers. These are located on the gas vapor generator.
No. 5) Valve: Gas liquid valve to regulate the gas pressure to the gas vapor generator. To be adjusted only when cleaning the burners or regulating the gas pressure by the L-shaped thumbscrew at bottom of the gas vapor generator.
No. 6) Valve: Main gas liquid valve located on the gas tank filler pipe.
No. 7) This is the pipe cap on the 3/4 inch filler pipe for the water tank.
No. 8) Shift Lever: For the water pump
No. 9) Shift Lever: For the Popper(s) (one or two levers depending on the number of poppers)
No. 10) Shift Lever: For the peanut roaster
No. 11) Valve: The throttle valve for the steam engine usually has two hard Maple knob’s. One is always located on the throttle valve next to the steam engine. The second, if present, is located on the end of a shaft attached to the throttle valve with a universal joint. This knob is located just under the steam table.
No. 12) Oil cup for the steam engine cylinder (oil displacement lubricator or needle valve metered lubricator)
No. 13) Valve: For the gas mantle light(s)/torch(es)--- same as No.6 on a second filler pipe
No. 14) Valve: Steam safety (popoff) valve set at 30 pounds pressure
The following two numbered valves have been added by Bruce Wm. Anderson
No. 15) Valve: Present only on the larger popcorn wagons, to provide gas vapor to the stove for melting butter. This is located on the gas vapor generator.
No. 16) Valve: The base of the lighter’s cup has a small tap (L-shaped thumbscrew needle valve) used to fill this cup with liquid gas.
The gas vapor generator flame must burn for several minutes before the main boiler burner can be turned on. It will take approximately 20 minutes for the water in the boiler to begin to steam. TOOLS: 1). Lifting Handle for the peanut roaster cylinder cover 2) Peanut Roaster Tester 3) Long Bent Needle to clean small holes in burners 4) Tip (Jet) Cleaning Tool 5) Spoon for removing check ball valves for cleaning 6) Funnel for filling the boiler at the water gauge and the water tank 7) Funnel (modified) for filling the white gas tank on pressure fed models 8) Funnel (plain) for filling white gas tank on gravity fed models 9) Matches to light the gas vapor generator burner
To remove the gas vapor generator: Numbers in the paragraph refer to numbers on the White Gas System page's labeled photos 1) Remove all the valves (37, 20, 13, 32, 24, and 25) 2) Loosen the ¼ inch pipe union on the gasoline generator next to the boiler case (gravity feed system) or loosen the flare nut (6) on the hollow wire gas tubing next to the boiler case (pressurized gas systems) 3) Open the sliding door under the generator 4) Open the back sliding door of the boiler casing which will allow the generator to be lifted out through this door. On larger Dunbar Popcorn Wagons the mounting bracket (14) must be unbolted.
S A E 30 automotive engine oil should be used in the three oiling cups located on the steam engine as well as all of the oiling points throughout the drivetrain. Always stop the crosshead under the oil cup upon shutdown of the steam engine and before oiling the steam engine. A light film of oil should be kept on the ladder chain used to drive the Automatic Buttering Device or the Rotary Air Popper on the No. 1 and No. 2 Wagons.
