My father Barry Thomas was executive vice president of Todd & Sargent from 1960 to 1983. I also worked there summers on slips and then full time from 1976 to 1983. In that time we had encounters with several Tillotson elevators as noted below:
- Bellwood, Nebr. is described in a previous post.
- Randall, Iowa. This Tillotson elevator’s design included a driveway with overhead bins. The bin bottom slab over the driveway separated from the slip walls and began to fail. We designed and installed a supplementary support system for that slab.
- Dike, Iowa. We removed all equipment from the elevator and the annex and installed a new, higher-capacity bucket elevator, a distributor to replace the pot-hole type distributor with larger spouts to the bins, and new enclosed drag conveyors to fill and empty the annex bins at the higher rate. We also installed “letdown” tubes in the three rail-side silos of the annex and installed a 30,000-bushel-per-hour rail load-out spout. The letdown tubes were quite revolutionary at the time for installation in older designed slipform storage structures to allow for higher withdrawal rates.

I worked for T. E. Ibberson Co. from 1985 to 1990 and 1993 to 1998.
I have over 200 slips on my personal resume and have designed many more that I did not ride the slip on.
Our business at T&S grew fast once we added slipform concrete to our offering. I was assigned responsibility of opening up new territories. These new territories included Nebraska, North Dakota, Arkansas, Illinois, Minnesota, and Missouri. I had many opportunities during my time of designing, selling, and building projects in these states to encounter Tillotson and Mayer-Osborn elevators. Of course, I wasn’t successful in obtaining an award on every project proposal!
Oftentimes, the owners of elevators that desired equipment upgrades or storage additions had original Tillotson blueprints, which made my job designing the solution to their issue easier.
At one point T&S purchased the assets of an elevator builder in Omaha named Ryan Construction. Their warehouse was in north Omaha. One of the items we obtained in the purchase was jacking frames for screw-type slipform jacks (top of post). All of my experience was with hydraulic and electric slipform jacking systems. I was intrigued by these screw jacks and did my own pre-internet research which included interviews with several of the “old-timer” superintendents we had at T&S. It was interesting.
In my time at T&S, I competed often with Mid States and Quad States construction companies. In fact, Gordon Erickson of Mid States tried unsuccessfully to hire my Dad away from T&S. I remember visiting his home and meeting his family. I bring this up because over the years I met several people with those two companies who either started their slipform-construction careers with Tillotson or their fathers did. Bob Russell took over Quad States after Larry Stratman died. In several discussions with him I understood that his father and uncles were Tillotson travelers.
