Offered is a possibly unique hand crank bench grinder made by Robertson Mfg., Buffalo, New York. Kenneth Cope lists Robertson Mfg. as being founded in 1900 to manufacture the Hero foot powered emory grinder. The company was renamed Robertson Drill & Tool Company in 1909. In any case, this particular item is a well-made tool with a ratcheting action that allows the user to maintain a fairly high wheel speed. The largest gear is labeled on its periphery "Robertson Mfg, Buffalo. N,Y" yes t is a comma between the N and Y. The hub of this gear is marked "Pat Appld For." T is no tool rest present, though one could easily be mounted on the machine--t are two possible locations. The possibility exists that this machine was intended to be mounted on a post, either as a hand crank unit, or with a foot treadle connected to the crank. Perhaps somebody with more information than I possess will be good enough to pass it along. I will add any information sent to this listing. The unit is in as-found condition, with a uniform patination. T are traces of black enamel in protected areas--perhaps 5% remaining. This tool is in working order, though it begs for a full restoration. No Reserve. Priority mail shipping.
