United States Yttrium – Architectural Plans   Leave a comment

I recently found most of the architectural plans that were drafted in 1955 and 1956, by the local firm Hitchcock & Hitchcock. All images are photographs of the plans. Citation:Architectural Sketches and Blueprints, 1907-1987, Box 13, Folder Number 1, Hitchcock & Hitchcock (Firm) records, Collection Number 09921, American Heritage Center, University of Wyoming.

The area site plan: Sheet one full

Items of note include: What is now Curtis Street is shown as a county road, and the original still bank on the west side of the building is still intact, as is the oil/water separator & water treatment plant. Pine Street dead ends exactly the same today as it did then; but Cedar Street isn’t included. The “Exist Power Line” is no longer present. The “Exist Gas Meter”, (lower right), today is a sealed gas line, and the “Exist 4″ C.I. water and Exist 6″ Sewer” still remain.

US Yttrium Exterior Elevation Sheet, Full sizeThe exterior elevation sheet. The draft called for concrete blocks and glass blocks for the windows. The also indicated the use of stucco for the exterior “walls” that were originally furnace walls. Any exiting opening that wasn’t going to be utilized were ordered to have bricks used as filler.

Plant operationsLayout of the first floor and uses for each area. The south factory floor was a storage area, the north area that was created between the refinery furnaces and the refinery machinery rooms was slated as a work room. Two of the machinery rooms became laboratories.
