orneus ARTHUR P. HAAE, 0F OHICAGO, ILLINOIS, ASSIGNOR TO OZONE PURE AIRIFIER COMPANY, A CORPORATION OF ILLINOIS.
Application filed April 14, 1921.
Chicago, county of Cook, and State of Illi- 1101s, have invented certain new and useful Improvements in Ozone Machines,- of which the following is a specification, and which are illustrated in the accompanying drawin s, forming a part thereof.
he invention relates to ozone machine elements which may be used singly or in groups as is customary in devices of this class.- The objects of the invention are to secure a high degree of eiiiciency, simplicity of construction and ease of assembling and disassembling the parts.
A preferred embodiment of the invention is shown in the accompanying drawings, in which- Fig. 1 is a side levation, partly in section, of the improved element;
Fig. 2 is an end elevation, the open position of one of the clamping devices being shown in dotted lines;
Fig. 3 is a detail longitudinal sectional view, and 1 4 is a transverse section on the line 4-4 of Fig. 1.
The improved element comprises a dielectrio 1( preferably of glass taking the form of a cylinder which may be closed at one end, as 11, for the purpose of preventing the circulation of dust laden air through it. The outer electrode 12 is formed of two sheets of metal 13, 14, each bearing alarge number of contact points, as 15, shown as being stamped from the metal sheet. The metal sheets 13, 14, are bent to semi-cylindrical form, the width of each being such that when the two are applied to the dielectric with the contact points 15 bearing thereagainst, they form substantially a complete cylinder.
'The other electrode 16, is preferably formed of a metallic foil and applied to the inner surface of the dielectric and is held in contact therewith by expansive spring elements, one of which, 17, is shown as an expansible metal band and the other, 18, 1s a helical coil of spring wire which preferably forms a part of one of the circuit wires 19.
The parts which-have been described being assembled are seated in a pair of chalrs 20, 21, each having feet 22, 23, which may be secured to a suitable support by means of Specification of Letters Patent.

screws. A curved clamping bar 24 is pivoted, as shown at 25, to one of the side arms of each of the chairs and may be closed down over the electrode 12. The free end of th bar 24 is provided with a hook 26 for engagement by a latch 27 carried by a hasp 28 pivotally attached, at 29, to the other arm of the chair.
The contacts 15 are of uniform len th so that all of them rest upon the die ectric when the parts are assembled. One of the circult wires 30 may conveniently be' connected with the electrode 12 through one of the chairs, as 20, and is shown as secured thereto by one of the securing screws 31.
In use a high potential current being passed through the circuit, an arc is developed between each of the contacts 15 and the electrode 16 causing the generation of ozone in a well known manner.
In devices of this general character, there being a circulation of air among the contact points 15, dust is accumulated which must be removed; By disengaging the latch members 27 and throwing back the clamping bars 24, the two parts of the electrode 12 and the dielectric mav be literally separated for the purpose of cleaning. r
