Description: |
| "This invention relates to improvements in holders for oil-stones; and consists of a pair of cast-metal plates, with pointed feet to use on the bench so as not to slip, arranged to clamp the ends of the stone at the top, and provided with a clamping-rod and screw between the top and bottom, and a brace below the rod, to cause the clamping force on the ends of the stone when the plates are secured up to the ends of the stone and the brace by the rod and its nut. The said plates are provided with flanges for the bottom of the stone to rest on, and sockets for confining the ends of the brace..."An example is reported, with the only marking being "PATENTED APRIL 26 1870" cast into one end. |
