Vanished Tool Makers: Cincinnati Tool Company





Note the detail stamped on the wings of the screw nut:



Below, their Super Jr. clamp series. 













Below, other of this company's clamps in my shop, demonstrating the range of their C-clamp offerings:


Earlier clamps were marked Cincinnati Tool Co. or C.T. Co.:


They even had a offering in the economy class,  stamped "Cin Craft" clamps with the body made in two pieces and spot welded together:



The Cincinnati Tool Company was founded in 1877.  By 1911 or 1912, Edward Hollister Hargrave who was running the company passed away.  His son, John Morris Hargrave, who had recently graduated from M.I.T., took over the helm.  In 1924, the company officially became the Hargrave Company.  A circled "H" on the tools indicates that it was designed by John Hargrave.



In addition to bar, C- and wooden jaw clamps, in its heyday the company also made cold chisels, star drills, spokeshaves, bit stock, clamps, pliers, punches, chisels, box scrapers, saw vises and machinists tools. In 1962 it was acquired by the Warren Tool Group (which also gobbled up Brink and Cotton).
