Long before the proliferation of completely automatic pinsetters, inventors were developing machinery and methods to make resetting pins between rolls and frames much simpler. In 1906, Backus Automatic Pin Setter Co. began operations in Smethport, Pennsylvania, to manufacture and market an automatic pinsetter. For decades, the company continued to improve on their original invention. They released the Spot-O-Matic pinsetter in 1940, and the machine promised to set pins more smoothly than previous models. As their technology improved, the company provided proprietors with updated operations manuals to ensure no pin would go unset.
