Description: |
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
"The glass knob, instead of being perforated, in the usual manner, for the reception of a metallic screw, is pressed into a mould, so made as to form the knob with a shank of solid glass, furnished with a screw. On account of the brittleness of the material, the shank is made large. The claim is to the making of glass knobs, having a glass shank, with a screw upon the shank."
