A chance encounter with a Tillotson elevator in Jamestown, Kansas

Sporting a fresh coat of paint, the trademark Tillotson elevator with its curved headhouse still operates. 

Story and photos by Kristen Cart

On our last elevator road trip, which our family embarked upon in October 2012, we visited many of our grandfathers’ elevator projects from the 1940s and 50s. But we also amassed a photo collection of elevators we could not place. Either the grain cooperatives were closed for business on a Sunday, or the elevators were retired, or we didn’t have time to stop for an interview. So the photos languished for most of a year, until Ronald Ahrens and I could identify them, even though we strongly suspected that the structures were the works of one of our grandfathers.

One of the mystery elevators was a pure white example, located in the north-central Kansas town of Jamestown. Ronald’s uncle, Tim Tillotson, recently handed us the Omaha builder’s construction specifications, which finally identified this handsome elevator as a project built in 1953 by the Tillotson Construction Company.

A smaller elevator stands on a branch of the rail line. It's builder is unknown.

The Jamestown elevator stands not far from a companion elevator, rising alone on a fork of the railroad track. The smaller elevator was built in a straight-up style that predates the more common Tillotson style, and it’s provenance is unknown. It is reminiscent of the style of the elevator built by Tillotson Construction in Greenwood, Neb., but without the curved headhouse. But it also recalls several Chalmers and Borton examples.

It is our good fortune to have the detailed specifications for the Jamestown elevator. Thanks to the Tillotson Company’s meticulous record keeping and the decades-long survival of the records, we can share the construction details of this remarkable structure. The specifications, for the engineering-minded among our readers, are presented below.

    By chance did one of your grandfathers companies built the grain elevator in Blue Rapids, Kansas? It looks just like the Jamestown photos with the rounded head house. Also, thank you for posting the measurements of the Jamestown elevator. I plan to build scale models of the grain elevators in Blue Rapids, Waterville, Greenleaf, and Washington, Kansas.

    • Hi Nate. Blue Rapids doesn’t sound familiar, but we will let you know if we turn up anything. Meantime, we would love to see photos of the finished models. Please stay in touch: maybe we could post them on Our Grandfathers’ Grain Elevators.

        If you will send me an email I’ll send you some photos of the Blue Rapids elevator and a few photos of the Clifton, Kansas, elevator a fellow modeler built. I saw the Dec 3rd entry on that elevator. My email is obermeyern AT yahoo DOT com. Thanks.

    Maybe I missed it, but what are the diameters of the silos for the Jamestown elevator? I can provide photos of Blue Rapids if you’re interested in seeing them.

    In the description of the Jamestown elevator, at the head of the data column, the specifications said “Like Meno, but split dust bin for bin #17.” So we go to the description of the 1953 Meno elevator to find: “5-16′ diameter Tanks-120′ [Height]; 13′ x 17′ driveway; 15 Bins & ov’flow; Dust bin over Ext.; 25 Bu. scale.” So with the exception of the dust bin arrangement, the two were the same. I hope this answers your question.

    We would be very interested in your photos! The model of the Clifton elevator would be very neat to see, also. Thank you.

    Here are the links to the photo of Blue Rapids, KS, elevator and a photo of Ken Jenkins model of Clifton’s elevator.



    Thanks,
    Nate
