as the incandescing memum or минта от глесто нашр от
for other Purposes.
I, THEODORE MACE of No. 14 Dey Street New York in the United States of
America but temporarily residing at the First Avenue Hotel in the County of
Middlesex Merchant to be as follows:-
This Invention relates to the treatment or manufacture of materials especially suited
for use as the incandescing medium or luminant of an incandescent Electric lamp
but which may also be used for such other purposes as it is or may be applicable to.
According to this Invention a carbonaceous substance or other electric conductor
or other suitable body base support or core is subjected to the action of high heat in
the presence of an organo metallic body.
The process when applied to the treatment of Electric conductors formed of a
compound of a like nature to that of the material which is deposited by the treatment
according to this Invention will thicken the material and insure its regularity. The
material body base or core selected is according to this Invention electrically heated
to a high incandescence (which can be effected electrically) in a vapour or liquid of
an organo metallic body. Thus for example an Ethyl or Methyl compound of
aluminium associated with an oxidizing agent may be used and for the purposes of the
invention the latter may suitably consist of watery vapour mingled with the aforesaid
vapour of the organo metallic body.
The material being treated being thus brought into contact with these vapours
effects a decomposition of the latter and the deposition of the required elements in and
upon the said material under the influence of the high temperature which elements

page_text: enter into chemical combination and produce a practically homogeneous covering
coating or material or thickening.
The material coating or thickening above described has a high degree of strength
and elasticity and resists the disintegrating action of the electric current when used as
a source of light, especially is it found to be perfectly stable in vacuo or out of the
pressure of free oxygen at the high temperature necessary.
As already stated the mode of carrying the invention into effect may be modified.
Thus instead of employing an ethyl or methyl compound of aluminium ethyl or
methyl compounds of allied metals such as nickel may be used.

as the Incandescing Medium or Luminant of Electric Lamps or
for other Purposes.
I THEODORE MACE of 14 Dey Street New York in the United States of America
Merchant do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This Invention relates to the treatment or manufacture of materials especially
suited for use as the incandescing medium or luminant of incandescent electric lamps
but which may also be used for such other purposes as it is or may be applicable to.
According to this Invention a carbonaceous substance or other electric conductor or
other suitable body. base support or core is subjected to the action of high heat by
passing an electric current through it whilst it is in the presence of an organic
compound of aluminium so as to obtain on the said body base support or core a
deposit of carbonaceous matter and alumina.
The material body base or core selected may itself be a compound of carbonaceous
material and alumina such as is described and claimed (and called "Erdite") under
my application for Patent No. 9694 of even date with this viz.:-the 27th day of
July 1886 or may be any other material suited to receive the deposit material or
compound according to this Invention.
I will describe this present Invention as applied to the treatment or manufacture of
a filament for incandescent electric lamps from which its application to the production
or treatment of material for other purposes to which it is or may be applicable will be
also understood.
I take the filament to be treated and I dip it into a liquid of an organo-metallic
nature contributing oxide of aluminium (such a suitable liquid is the Ethylate or
methylate of aluminium) and I pass an electric current through the filament whilst it
is in a vacuum or out of the presence of oxygen or gas which would cause its
consumption or injure it. The filament is thus incandesced in the presence of the said
liquid of an organo-metallic body of the nature described and by this means a
decomposition of the liquid is effected and a deposit of carbon and alumina takes place
upon or in and upon the incandescent filament and the result is that the article has
imparted to it and consolidated with it an even covering coating or deposit of the
nature described. When the body treated as explained is of the nature described as
aforesaid in the Specification of my application for Patent No. 9694 of 1886 the
deposit formed thereon will be practically a consolidating and rendering uniform by
what when the process is completed forms an integral part of the body treated as it is
of the same nature therewith.
The material coating or thickening obtained as described has a high degree of
strength and elasticity and resists disintegration by the electric current when used as

page_text: a source of light and especially is it stable in vacuo or out of the presence of oxygen
at the high temperature necessary for electric lighting.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :—
First: The manufacture or production of a material suited for use as the
incandescent or luminant of electric lamps or for other purpose consisting in
subjecting a body base support or core to electric heat in the presence of an organic
compound of aluminium such as Ethylate or Methylate of aluminium substantially as
herein before described.
Second: The manufacture production and use of a material suited as the
incandescent or luminant of electric lamps or for other purpose the said material
being produced by depositing by the action of electricity a material consisting of or
containing carbon and alumina substantially as hereinbefore described.
