CARBONISER (For Light Bulb Filaments)
Thomas A. Edison, Menlo Park, NJ
wood, brass and metal, signed, glazed case (later)
6½ x 8½in.
Note: Everyone knows who Edison was. He invented the light bulb, a few years before this particular invention (which does relate to the light bulb). Edison also holds the record for the most patents ever issued to a single individual 1,093.
This particular invention was to "carbonize" the filaments that were used in his lightbulb. And as the patent specifications point out, "The object of this invention is to furnish means for carbonization which will insure convenience of operation economy and equal carbonization." The operation of the invention was a little more complicated.
By controlling the mixture of air and gas let in the interior chamber, Edison proposed to form a carbon filamant that would be uniform in size, and would not warp or twist once installed in a light bulb. Different substances were carbonized. In fact Edison once had a world wide treasure hunt going to find the best substance for carbonization. Before tungsten was discovered, bamboo turned out to have the best qualities for providing light for the world.
