content: This is a patent model for a balanced water elevator, patented on March 8, 1870 by William L. Thomas of Wadsworth, Ohio. The invention was a balanced water-elevator using two working barrels with pistons connected to a common beam. As one piston lifted water through valves into rising pipes, the other filled, creating a counterbalance that gave smoother, continuous pumping with less effort.
