Was behind a homemade pickup box trailer and seen the DE WORM DRIVE riveted on the frame. Just curious what this was. The plate was 2 inches by 12 inches. thanks chris

I don't have a clue. It's a pieced together trailer, a little 4x6 pickup box with different fenders, a front axle for the axle, and the riveted sign is actually upside down, with some leaf springs from something else. wood/trash hauler

This might be a worm drive. Screw drive would be more fitting.

"Fordson Snowmobile 1926
This was known as an Armstead Snow-motor. Hauling capacity was said to be five tons. Each drum receives power from a separate clutch which, depending on the position of the steering gear, engages and disengages. It can also traverse bare ground. This machine hauled mail from Truckee to North Lake Tahoe." (Quote from website above)
I believe the video tractor was built by another mfg in 1920. It could be Ericson.
There is probably a pinion gear in the center of the rear housing. That would drive left and right hand gears opposite one another. The gears probably turned clutchable shafts than ran to the sprockets. You can see the lever that controled the clutches. It is connected to the steering wheel thru a drag link and pitman arm.
Nowadays it would be hydraulically driven. Apparently, the oil companies in Alaska have used these screw drives as they are very easy on the tundra in all seasons.
