UNITED STATES PATENT OFFICE.
JAMES SWINBURNE, OF WVESTMINSTER, ENGLAND, ASSIGNOR TO,THE ELECTRIC RESISTANCE & HEATING COMPANY, LIMITED, OF LONDON,
. ENGLAND.
HEATER FOR ELECTROLYTIC INCANDESCENT LAMPS.
SPECIFICATION forming part of Letters Patent No; 681,352, dated August 27, 1901.
Application filed January 8, 1901. Serial No. 42,562. (No model.)
To all whom it may concern.-
Be it known that I, JAMES SWINBURNE, a citizen of England, residing at 82 Victoria street, Westminster, in the county of London, England, have invented certain new and useful Improvements in Heaters for Electrolytic Incandescent Lamps, (for which I have applied for a patent in Great Britain, dated June 16, 1900, No. 10,940,) of which the following is a specification.
My invention has reference to heaters for electrolytic incandescent electric lamps.
Resistance-heaters can be made of carbon or metal or other conductor mixed with clay; but when the conducting material oxidizes in the air at the temperature necessary for a heater the resistance is greatly altered and can no longer be used as a heater. To overcome this difficulty, I protect the oxidizable conducting material against the action of the air by vitrifying the insulating material or by glazing it.
A resistance-heater according to my invention may be made as follows: Graphite is kneaded up with kaolin and squirted into the form of thin rods or spirals. These are dried and baked at such a high temperature that the kaolin is Vitrified. To facilitate this vitrification, the kaolin may have feldspar added to it, or the clay used for making china may be e loyed instead of kaolin and feldspar.
In s l ad of vitrifying the resistance it may be glazed by dipping it after it has been fired into water having glaze suspended in it and then firing it in the usual way. Glazes which are soluble in Water, such as boracic acid, may be employed.
Oarbids, silicides, silicon, or finely-powdered metal, such as tungsten, (preferably prepared by electrolyzing a fused tungstate,) may be employed as the conducting material instead of carbon.
Having thus described the nature of this invention and the best means I know of carrying the same into practical efiect, I claim- A resistance-heater for an electrolytic incandescent lamp consisting of a conducting material such as carbon mixed with non-con ducting material such as kaolin formed into the desired shape and vitrified or glazed substantially as and for the purpose set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IIGSSGS.
