LOUES GOLDBERG, F INDIANAPOLIS, INDIANA.
To all whom it may concern:
Be it known that I, Louis GOLDBERG, a citizen of the United States of America, and a resident of Indianapolis, county of Marion7 State of Indiana, have invented certain new and useful Improvements in @senators7 of which the following is a speciiication.
The main objects of this invention are to provide an improved forni of ozonator; to provide a simple'and eiiicient construction of central terminal; to provide an improved and inexpensive form of conductor terminal with positive contacting mechanism disposed upon a substantial dielectric; and to pro vide an improved form of construction in which the Working parts are readily removable from the casing, giving access-to the air passages.r
An illustrative embodiment of this inven-v tion is shown in the accompanying drawings, in which I Y Figure 1 is fa longitudinal section of an ozonator assembled, the central terminal being in elevation. Fig. 2 is the dielectric tube, with the conductor and terminal contact spring in place. Figr is a sectional View on the line A-A of Fig. 1. Figrd isla sec' tional view on the line B-B of Fig. 1.
In the form shown, acasing 1 forms a housing for the Working oit' the mechanism and a conined space through which air isy passed in the process of producing ozone.) Loosely fitting the internal Wall of the casing is a tube 2 of dielectric material. round on the central portion of ythe external surface of the dielectric tube is an insulated conductor 3. A metallic band l encircles the tube and has its ends bent outward to provide lugs which are connected by a screw and serve as ay combined clamp and terminal post 5 to which is secured the adjacent end of the conductor 3. One end of the casing 1 is provided with i spacing block G which is provided with air distributing passages 7. The spacing block 6 is provided with a shoulder 8, which contacts with one end of the dielectric tube?. The external surface ofthe spacing block 5 is turned to lit the internal surface of the dielectric tube 2.
, An inlet for air to the apparatus is provided by a tubular projection 9 which is. fitted into thel center of the lower end of the casing 1. A support for a central or inner i electrical terminal is provided by a metallic sleeve 10, which occupies the center oi' the spacing block 6. Screw-threaded luto the Specification of Letters Patent. Patented June 20, 1911,
Application filed February 10, 1911.
Serial No. 607,845.
sleeve 10 is an inner terminal rod 11 which is' provided at its upper end With a head 12 and `a baffle plate 13. A number of longitudinal slots 14 are cut radially in the cent-ral rod 11., Fitted into each slot is a fiat metal strip which is secured in the slot by prickpunching the rod close to the slot after the strip 15 has been inserted in the slot. The external ed e of thestrip 15 is provided with serrations orming a large number of discharge points from the inner termi-nal. Electrical contact, with the central terminal is formed by a metal connector 16 .which is secured to the metallic sleeve 10 by a machine screW 17. The connector 16 isalso secured to a terminal post 18 which projects throughl the casing 1. Betweenthe connector 16 and the spacing block G is placed a Wire screen 19 which completel covers all of the air Vdistributing passages The electrical contact With the conductor 3 is made by Way of the metallic strip f1 with a resilient metal strip 20, which is so securedto the inner surface of the casing 1 as to yieldingly bear toward the strip 4f. The usual terminalpost 21 is located exterior to the casing and is in metallic con'- t-act with the spring contact strip 20 through the machine screw 22. Insulated thumb nuts '23 are secured to the upper Aend of the cas: ing lon threaded pins 24. These thumb nuts may be used to secure a collector or cap to the delivery end of the casing.
In operation, the terminal posts 18 and 21 are connected to the secondary of a transformer or to any source of electromoiive force of .the required potential and frequency.
Then the terminals are so connected, an eiiluve or silent discharge Will take place between the inner and outer conductors.
When the apparatus is in operation, a current of air is forced into the inlet 9 Where it enters a cavity communicating with the air distributing passages 7. The air passages aresymmetrically distributed in close proximity to the dialectric tube. As the 'process progresses, the ozonized air is forced out ofthe cent-ral rod 1l from the sleeve 1.0, whereupon it can be withdrawn through the open top of the casing. The dielectric tube with its conductor and ucontact member m'ay be slipped ott from the block 6 and the block 6 may be disconnected from the casing by merely nnscrewing thc binding post 18 from the screw shank by which it is connected to the contact member 16.
Although but one specific embodiment of this invention is herein shown and described, it will be understood that'numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention, as defined by the following I claims.
1. An ozonator, comprising a casing having a contracted inlet opening at one end, a block seated over said opening and having therethrougha series of distributed air pas sages communicating with said inlet opening, a dielectric tube mounted in `said 'casingv and having its interior in communication with said distributed air passages, so as to provide a continuation thereof along said casing, an outer electrode disposed around the outside of said dielectric tube, an inner electrode carried by said block, being located concentrically within said tube and comprising la metallic body shaped to provide a multiplicity of distributed projections uniformly spaced with respect, to said outer electrodes, and means for connecting said electrodes to a suitable source of electroinotive force.
2. An ozonator comprising a casing havim@T a contracted inlet. opening at one end, a block seatedA over said opening and having theretlnough a .series of distributed air passages communicating with said inletl opening, a dielectric tube mounted in said casing and having its interior in communication with said distributed air passages, so as to provide a continuation thereof along said ing a metallic body shaped to provide a multiplicity oli' distributed projections uniformly spaced with respect to said outer electrode, and 'means for connecting said electrodes to a suitable source of electromotive force, and coniprising a binding post A having a shank extending loosely through said casing' aud sccaued to said block and thereby serving' to hold said block in position in said easing.
3. An ozouator, coniprisii'ig a casing hav- 60 ing a contracted inlet. opening at one end, a blocl-I litting within said casing adjacent to said inletLand having therethrough a plurality ol' distributed air passages communicating with said inlet, a cylindrical shoulder formed on said bloch, a tubular dielcet ric tit;- ting said shoulder and adapted to be supported thereby in said casing, an outer electrode disposed around said dielectric tube, an inner electrode having screw-threaded connec- 7o tion with said block and located concentrically within said tube, said electrodes being formed to provide opposed projections distributed throughout the contiguous areas of said electrodes, the projections on one of Said electrodes bcinsr uniformly spaced away trom those on tic other, the end of said casing which is opposite said contracted air inlet'. laing arranged to permit said block, dielectric tube and clcctrodes to ,be \\'ithdra\\'u thercthrough, and means for connecting said electrodes with a suitable sourct` ot' eltwtroufiotive torce.
