Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed February 17, 1905. Serial No. 246.026.

To all whom it may concern:

Be it known that L ALBERT C. Woon, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Electrical Apparatus for Producing Ozone, of which the following is a specification.

This invention is designed to provide improved means for producing ozone by discharging a high-tension electric current in an atmosphere of oxygen, and particularly to produce an apparatus having improved electrodes and holders therefor.

The nature and characteristic features of the invention will more fully appear by reference to the following description and the accompanying drawings in illustration thereof, of which'- Figure 1 represents -a side elevation, partially in section, of an apparatus embodying my improvements. Fig.2 represents an end elevation of the structure shown inFig. 1, the cover of the air-inlet chamber being removed to illustrate the interior construction, Fig. 3 represents a transverse sectional view taken through a conduit containing electrodes and connections made in accordance with my invention. Fig. 4 represents a broken longitudinal sectional View of the structure illustrated in Fig. 3. Fig. 5 represents a transverse sectional View of a structure analogous to that shown in Figs. 3 and 4, showing a modified electrode for collecting the charge from the dischargers; andFigs. 6, 7, and 8,

show transverse sectional views of several modified forms of dischargers and supports therefor.

As shown in the drawings, tubular conduits 1 are vconnected to the chambers 2 and 2', having, respectively, the passages 3 and 3', the conduits being set in the tube-sheets 4 and 4 of the 'chambers and being accessible by removing the covers 5 and 5' thereof. In the ends of the conduits are fitted or frictionally engaged the insulating-'caps 6, which engage the ends of rods'7 for carrying the electrodes 8, having the branches 8', the caps being sleeved on the ends of the rods and held thereon against the electrodes bythe clampnuts 9 and 9'. The nuts 9 are provided with the binding-posts 10 for making' electrical connection between the conductor-'11, passing into the chamber 2 through the insulation 12, and the electrodes 8, which are electrically Connected with the binding-posts through the rods 7. The caps have the openings 13 therethrough arranged in line with the several branches or brushes 8'. Insulating-spiders 14 are sleeved on the rods and are freely 'movable in the conduits, being disposed between the ends of adjacent electrodes 8 and having openings 15 therein in line with the several electrode branches, it being the purpose to dispose the electrode branches and passages in the several conduits so that the air-currents and electric discharges will intersect each other. As shown in Figs. 3. and 4, the aper'- tures 15, through the spiders, register with the longitudinal conducting-strips 16, fastened to the conduit 1 in the plane of the respective branches 8', the strips serving as guides for the spiders and as receiving-electrodes, -discharging through the binding-post 17, electrically connected therewith.

. The rod 7 is provided with the' longitudinal concavities 18, which are formed therein to provide seats for the discharging-electrodes, which are formed by bending sheets of metal to fit the seats and provide the 'branches 8', disposed radially with relation to the conduit, these electrodes being clamped to the rod'by the strips 19, placed in the concavities thereof, and by screws 20,passed throughthe strips and the electrodes.

As shown in Fig. 5, the rod 7 holds the brushes 8' in line with the apertures 15 of the spiders 14, freely movable in the-,metal conduit 1, havinga nickel lining 1' in place of the strips 16.

As shown in Fig. 6, the conduit 1, with the nickel lining 1', has the hollow rod 21 sup.

ported therein by the spider 14, the rod Ahaving the sheet-metal strips 22 fixed to the exterior thereof by the screws 23, the strips having the brushes 22' turned up from the foot thereof in the direction of the radii and in line with the apertures 15.

As shown in Fig. 7,'the metal conduit 1, with the nickel lining 1', contains a spider 14', having an increased number of apertures 15' therein. The rod 7 ',Ksupported by the spider,

has an increased number of electrodes 8 withradiating branches 8', which are held by strips 19' and screws 20 in line with the apertures through the spiders and the caps.

As shown in Fig. 8, the electrode contained in the conduit may consist of a plurality of brushes 24, formed in pairs connected rby webs 25, xed together by rivets 26 and supported in the conduits in any suitable manner.

It will be understood that air is carried IOC through the conduits 1 from the chamber 2 and inlet 3, and the ozonized air therefrom is discharged into the chamber 2' and thence through the outlet 3. As the air flowing through the conduits must pass through the openings in the caps and spiders, the most active currents of air are found in the lines thereof, and as the radially-disposed brushes or branches of the electrodes project in planes that are coincident with these currents it will be understood that the .bulk of the discharges from the brushes to the strip-electrodes carried by the conduitsor to ,the conducting material of the conduits themselves intimately mingles with the bulk of the air. As the caps and spiders have' merely frictional engagements with the conduits, it will be understood that by reinovingthe cover of an air-chamber and detaching the caps at one end ol the rods these rods, with the electrodes and spiders thereon, can readily be Withd rawn and as readily inserted.

The structure is eilicient in operation, siniple and economical in construction, and read- Iily assembled and dissociated.

Having described my invention, I claim- 1. In apparatus of the class described, a tu bular conduit, an electrodecomposed of sheet metal bent 4along its length intermediate of its edges to provide a plurality of discharges, and insulating-supports for holding said electrode in said conduit.

2. ln apparatus of :the class described, a tubular-conduit, a rod in said conduit, insulatingsupports for holding said rod in said conduit, and an electrode bent along its length intermediate of iits edges to provide a plurality of diverging members fixed to said rod.
