Abstract
4502. Brewer, E. G., [Edison, T. A.]. Nov. 7. Incandescent lamps. - The filament X consists of fine particles of metal or metallic oxide moulded into a cylinder, prism, or other form, and is made slightly tapering and split vertically, except at the upper end, so that the current passes up one side and down the other, the base of the cylinder being enlarged so that the electric conductors can be connected to it. A thermal circuit regulator n, described in Specification No. 4226, A.D. 1878, expands and short-circuits the current when it is excessive. The fine particles of metal may consist of platinum, iridium, ruthenium, or other metal of very high melting-point, and are caused to adhere by infusible earthy materials, such as magnesium or zirconium oxide, lime, silicon, or boron. The filament is moulded in either a moist or dry condition by pressure ; and sugar, tar, silica, or similar material may be used in moulding, these substances being volatilized by the heat. The oxides or earthy materials may be thoroughly and uniformly mixed into the mass before it is moulded ; or rods or prisms of oxides may be saturated with a salt of a metal difficult of fusion, and this salt reduced to the metallic state by heat.
