Claim 5

An assembly in accordance with claim 3 wherein each of said couples is joined to a spring tensioning means to maintain said wires in predetermined tension.

Claim 6

An ionizer assembly for an electrostatic air cleaning assembly comprising first and second parallel spaced channel shaped members defining therebetween an ionization region transverse to airflow therethrough, the first of said channel members defining a plurality of spaced openings in the outer surface thereof and extending along the length thereof, the Second of said channel members having a plurality of spaced wire mounting means along the length thereof corresponding in position to said openings, ionization wire joined at each of said wire mounting means and extending around the outermost edges of each of said channel and across said openings thereby defining a plurality of spaced ionizer wire couples, spring and hook means interior of said first channel members in engagement with the wire passing over each of said openings and drawing a portion of said wire through said opening to produce a predetermined tension on each of said wires in a couple, grounded ionizer tubes forming an array of tubes upstream and generally parallel to the upstream ionizer wires and a second array of grounded ionizer tubes downstream of and generally parallel to the downstream ionizer wires, said tubes being positioned along planes intermediate adjacent ionizer wire couples.

Claim 7

An ionizer assembly for an electrostatic air cleaning assembly comprising first and second parallel spaced channel shaped members defining therebetween an ionization region transverse to airflow therethrough, the first of said channel members defining a plurality of spaced openings in the outer surface thereof and extending along the length thereof, the Second of said channel members having a plurality of spaced wire mounting means along the length thereof corresponding in position to said openings, ionization wire joined at each of said wire mounting means and extending around the outermost edges of each of said channel and across said openings thereby defining a plurality of spaced ionizer wire couples, spring and hook means interior of said first channel members in engagement with the wire passing over each of said openings and drawing a portion of said wire through said opening to produce a predetermined tension on each of said wires in a couple, grounded ionizer tubes forming an array of tubes upstream and generally parallel to the upstream ionizer wires and a second array of grounded ionizer tubes downstream of and generally parallel to the downstream ionizer wires, said tubes being positioned along planes intermediate adjacent ionizer wire couples.

Claim 8

Claim 9

An ionizer assembly for an electrostatic air cleaning apparatus comprising first and second spaced ionization wire support members, said support members having a forward and a rear edge respectively with respect to airflow therebetween, a plurality of ionization wires formed from a single length of wire extending between said first and second support members at the forward and at the rear edges thereof to define a plurality of couples of ionizer wires, said couples being generally aligned in the direction of airflow, spring means connected to said support member and to one point on each of said plurality of couples of ionizer wires to maintain the wires of said couple in tension, grounded ionizer tubes forming an array of tubes upstream of and generally parallel to the upstream ionizer wires and a second array of grounded ionizer tubes downstream of and generally parallel to the downstream ionizer wires.

Claim 10

An assembly in accordance with claim 6 wherein one point on each of said couples is fixedly joined to one of said support members.

Claim 11

An assembly in accordance with claim 7 wherein said spring means comprises integral spring and hook members with the hook passing through a hole in one of said ionization wire support members to engage said wire to individually tension each of said couples of ionizer wires.
