SPECIFICATION forming part of Letters Patent No. 565,952, dated August 18, 1896.

Application filed A ril 3, 1895. Serial No. 544,347. (No model.) Patented in France April 14,

June 2, 1892, No. 99,236; in England November 14, 1893, in Switzerland February 24, 18 94, No. 7,997-

To all whom it may concern:

Be it known that I, EMILE ANDREOLI, a citizen of France, residing at London, in the county of Surrey, England, have invented certain new and useful Improvements in the Production of Ozone and Luminosity by Electricity, (patented by me in Great Britain November14, 1893, No. 21,707; in France April 14, 1892, No. 221,176; in Belgium June 2, 1892, No. 99,236; in Germany November 16, 1893, No. 77,925, and in Switzerland February 24, 1894, No. 7,997,) of which the following is a full, clear, and exact description.

In my British patents, Nos. 17,426 of 1891, 9,631 and 21,794 of 1892, and in my United States application, Serial No. 444,064, filed August 25, 1892, I have described a mode of producing ozone by means of the silent discharges generated by an electric current from points, sharp angles, asperities, and the like.

The object of the present improvement is the construction of ozonizers with vacuumtubes in combination with electrodes, whereby ozone and luminosity or light are simultaneously produced. This is eifected by the tual edges as are afiorded by serrated wires, fret-saws, or the like, in combination with vacuum-tubes or tubes containing more or less rarefied gases, or with incandescent lamps, or other similar sealed dielectric vessels.

In the accompanying drawing the figure paratus comprehended by my invention.

The-tubes a are provided inside withan electrode b, consisting of a carbonfilament or a metallic wire or rod, or severalwires or rods, or with a bundle of small serrated wire, acting as an electrode, the points of which radiate, so as to face the inside of the glass tube, or with any other convenient internal electrode. Outside the tube, and in proximity to it, either longitudinally, spirally, as shown, or otherwise, some serrated wires or other equivalent metallic electrodes 0 are fixed in any suitable manner. One end of the wire,

transformer. The external metallic electrode a of the tube is connected with the other pole and as soon as the electric current passes, the inside of the tube becomes luminous, and at the same time on eachof the points of the serrated wires, fret-saws, 80.0., the character,-

istic glow of the silent discharge appears and is accompanied by a strong smell of ozone.

It is a well-known fact that the silent dis charge produces a bluish or violet glow; but

the luminosity of which I speak here is quite distinct from the glow generated by the silent discharge. In my vacuum-tubes I have both the glow of the silent discharge outside, and what I call luminosity inside the tubes, and this combination not only has never been patented before, but is scientifically a new phenomenon which disruptive discharge in, ordinary vacuumdiffers as much from the tubes as the internal luminosity of the tubes diifers from their external glow, and, to the best of 'my knowledge, nothing similar has ever been made before.

Having now particularly described and ascertain ed the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is An apparatus for the simultaneous production of ozone and luminosity or light which consists of point-bearing electrodes such as metallic serrated wires, points, &c., disposed outside of, in close proximity to,but out of contact with a vacuum-tube "lectric lamp, or similar device constructed J1. dielectric material, in combination with said tube, lamp or the like, internally provided with one or more electrodes, and a source of high-frequency al-.

ternating currents, the terminals of which are connected respectively with the said electrodes outside and inside. of said vacuumtube, lamp, or the like, substantially as described.

I In testimony whereof I subscribe my signature in presence of two witnesses.
