When I visited the office of High Plains Co-op, in Meno, Okla., Matthew Thomsen dug out drawings of the 152,000-bushel elevator that Tillotson Construction Co. built in 1953.
I took quickie photos with my phone.
The first drawing shows the leg, noting the right side is the “up leg” and the left side is “down leg.”
That’s so it isn’t installed backwards.
The tanks, or silos, are 16 feet inside diameter. To get an idea where that rates, consider how Tillotson started in 1939 with tanks 12-feet in diameter. Most of the elevators I’d visited so far on my road trip had 20-foot tanks, but the Ralston, Iowa, storage annex Tillotson put up in ’53 boasted 28-footers.
There is a truck lift and dump grate in the internal driveway.
Inside the headhouse, an automatic scale feeds a load-out spout that drops all the way to a rail car on the siding. Dig that draftsmanship by Ted Morse, whose initials appear in the information box seen in the third photo.
The next drawing shows details of the work floor including nine-foot-wide dump grates. We see the electrical room and, on the far right, a dock.
The drawing also shows the bin plan with 16 bins of various sizes and shapes. A handwritten notation on Bin 9 says, “Scales.” At the far end is the dust bin.
Both drawings adhere to a scale of 1/4 inch to 1.0 foot.
The final portion shows bin capacities in a list with some amendments. Penciled above the identification box, the note says, “Imo,” referring to the prototype for this elevator built in 1950 at Imo, Okla.
The plan was revised, according to another note, on Aug. 1, 1952.
We see in the box on the lower right that this is a standard-plan 154,000-bushel reinforced-concrete elevator. But how to account for the 2,790-bushel discrepancy between the plan and the construction record, which lists Meno at 152,000 bushels?
Thanks to Tracie and Matthew, of High Plains Co-op, for hauling out these drawings.
