Upson Nut Co Andrew Upson was the President of the Upson Nut Co which was established in 1872. The Standard Rule Co was the youngest firm in this group. Standard Rule’s factory was located in Unionville, Connecticut. Within three years the Standard Rule co had become the fourth largest ruler manufacturer in the United States. It is not known if they began operation from scratch or by purchasing another rule manufacturer. The Standard Rule Co. used the same nomenclature and rule numbering as Stanley. By the turn of the century most small rule makers in the United States had either ceased operations or been bought out by the large Connecticut makers. By this time virtually all the rules made in the United States were produced by Stanley, H. Chapin’s Son & Co., Stephens & Co., The Lufkin Rule Co., and The Upson Nut Co. which had absorbed the Standard Rule Co in 1889. In 1920 more of the rule manufactures were dropping out and it saw the departure of two competing manufactures. The rule division of Upson Nut Co and the Chapin-Stephens Co. The Upson Nut Co, now a Cleveland based manufacture of nuts and bolts had retained its rule division in Unionville, Connecticut, when Stanley purchased its hand tool division in 1893. Finally in 1922, The Upson Nut Co., abandoned the last vestige of tool making and sold the rule division to Stanley. The same day I ran across the Stanley No.1 Odd Job tool, I also found this Upson Nut Co. No. 68 boxwood rule. The round joint, the center disk was attached to a plate which was embedded in a slot in the end of one leg and held in place by steel pins driven through the leg and the plate. This joint was the cheapest, weakest and the least decorative of the three type of main joints used on boxwood and Ivory rules. Excited to add this old rule to my collection of Boxwood two foot four fold rulers. Always out Patriot Picking!
