Tillotson Construction’s elevators were unique, with some features that I have not seen from other elevator builders. One major feature was the curved head house. I have only seen one other company that produced an elevator with the curved headhouse. Another feature was that Tillotson put windows for light into the basement. Of course they had electric lights in the basement. I have not seen another builder put windows in the bottom part of the elevator. This must be a Tillotson trademark. This elevator has the year of construction added to the manhole covers. It shows 1958. Tillotson did a great thing by adding this. All the elevators that I have been inside, I have not seen another company put the year on the manhole covers. The date was on each manhole cover inside the elevator.
