Description

UNITED STATES PATENT OFFICE.
PATRICK N. MACKAY, OF SAN FRANCISCO, CALIFORNIA.
MANUFACTURE OF INCANDESCENTS.
SPECIFICATION forming part of Letters Patent N0.325,257, dated September 1, 1885.
Application filed August 13, 1884. (Specimens) I (tZZ whom it may concern;
Be it known that I, PATRICK N. MAoKAY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented and discovered certain new and useful Improvements in the Production and Manufacture of Incandescents for Electric Lights; and I do hereby declare that the following is a full, clear, and exact description of my said invention and of the manner in which I proceed to produce and make incandescents in accordance therewith.
For the purposes of my said invention I employ as the principal element or substance the mineral oxide of titanium,or asitis obtained in cit-her of the forms of anatase or octahedrite, rutile, and brookite, or as it is found in titani ferous minerals and other combinations of titanic acids. I reduce the substance to an impalpable powder by any suitable means, and proceed to form a pasty mass of proper consistency to take and retain the shape and forms required upon the application of pressure af' ter the manner generally followed in manufacturing electrodes. I produce the paste or material from which to make electrodes according to my invention by combining ahydrocar bon oil and the powdered oxide of titanium together, and I use for this purpose any suitable hydrocarbon, animal, vegetable, or mineral oil having suitable consistency to form, with the powdered mineral, a paste or pasty mass. The proportions that I have found suitable are from fifteen to twenty parts of thehydroearbon to one hundred (100) parts, by weight, of the powdered oxide of titanium;
but I do not confine myself to these particular proportions.
In manufacturing incandescent-s from this material I proceed to mold the paste into strips or ribbons or other forms and subject them to great pressure by means of a hydrostaticpress. In the course of this operation I produce a skin or protecting-shell upon the surface of the finished incandescent by covering the faces of the molds and the surface of the strips or pieces of paste with the powdered oxide of titanium in a dry state. This has the elifect to absorb any excess of moisture in the strip, and thus give greater solidity, as well as to produce an external skin on the finished incandescent.
I am aware that among other highly-refractory metals'suited to the purpose titanium in the form of beads, rods, and strips has been suggested for the light-giving part or body in incandescing lamps, and I therefore make no claim, broadly, to such a point or conductor from the metal titanium or from the oxide of that metal by itself; but,
Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is-
The herein-described material for the manufacture of electrodes for electric lights, consisting of the mixture of the oxide of titanium in powder and a hydrocarbon oil, substantially as herein set forth.
