l erases I claim:

1. 'An apparatusfor sterilizing water and other liquids by means of ozone comprising a vacuum tube, said vacuum tube containing mercury, an electrode mounted within said vacuum tube, an outer electrode arranged concentrically with and surrounding said inner electrode, an air passage between said electrodes and means for aspirating air through said air passage and into contact with the liquid to be sterilized.

2.` An apparatus for sterilizing water and other liquids by means of ozone, comprising a liquid inlet tube, a series of cones forming an injector, said inlet tube dipping into the uppermost cone of said injector, two electrodes, said electrodes being arranged concentrically one within the other, a vacuum tube within which said inner electrode is i mounted and an air passage between said electrodes communicating with said injector and the atmosphere. f

3. An apparatusy for sterilizing water and other liquids by means vof ozone, comprising a liquid-inlet tube, a series of cones formin an injector, rings welded to said cones an holding them superposed, said inlet tube dipping into said injector, two electrodes, said electrodes being arranged concentrically one within the other, a vacuum within which" said inner electrode is mounted and an air passa e between said electrodes communicating with said injector and the atmosphere.

4. An apparatus for sterilizing water and other liquids by means of ozone comprising an upper portion, an inlet tube communieating therewith, an injector arranged in said upper portion, said injector consisting of concentric superposed cones, a tube for the passage of the said tube being arranged below and concentric with said cones, an air passage concentric with and surrounding said liquidpassage tube, said air passage communicating with the atmosphere and the injector, a lower portion comprising a central tube forming a continuation of said upper liquidpassage tube, said central tube, said vacuum tube containing mercury, an electrode in said vacuum tube, an air passage surrounding said vacuum tube, a second electrode surrounding said air passa e, inclosed by t e -oeuter`wall of said, lower portion.

In witness whereof I have hereunto set my hand in presence of two subscribing witnesses this 9th day of August 1910.

closed at the bottom and arranged concentrically in the interior of the lower receptacle b of the apparatus. rIhe latter is fitted with an outlet pipe n which may be provided or not with a cock.

The apparatus works similarly to that described in my French Patent 408317 that is The Water or other liquid to be sterilized enters at 1 and passing through the extension 1a into the injector produces a suction in the latter, at 3, of ozone or air strongly charged with ozone, resulting from the ozonization of the atmospheric air. This air is drawn in by the suction produced at 5 5, enters through the bottom of tube CX the annular space between this tube and tube cy, where it is ozonized by the action of the electric discharges which (terminals g and i" being suitably connected to a convenient source of electric current) take place between the electrodes 0 p across the vacuum and across -the space existing between tubes cY and c". From there the ozone, or air charged with ozone produced in this manner rises through holes jy, annular space jx and the flaring mouth jz into the upper receptacle a.. The ozone or air strongly impregnated with ozone drawn in in this way at 3 is sucked in by the liquid into the injector 2 and tube y' where it mixes intimately with the) liquid and sterilizes it. The water or other liquid being thus sterilized falls through tube y intothe lower receptacle b where, owing to the vsinuous path it is forced to travel by. the baifles or partimixed with the ozone and thus insuring its perfect sterilization before arriving at the outlet pipe n.

Instead of using the arrangement shown in Fig. 1 for the passage of the air laden with ozone from receptacle c to receptacle a, a shunt or by-pass could be arranged between the two, as shown in Fig. 2, consisting of a tube a, made in two parts, with a ground joint at zo. In the same way in stead of only a sing e baiiie or partition y0 as shown in Fig. 1, a .number of such baffles could be arranged within the lower recepr tacle b`for the sterilized liquid, as shown at y, y1, y, Fig. 2 'so that the liquid is forced to travel a longer distance, during which it is brought into intimate contact with the ozone, before 'reach'ng the outlet n. The operation is evidently exactly the same in other respects as in the preceding case.

It will be obvious that my invention is not details of construction shown, for it ,is evident that they can be alter'ed to a certain extent as necessitated by practical requirements or as may be considered expedient.
