Claim 4

The ventilator housing set forth in claim 1 in which a cover having depending marginal flanges is secured to and supported upon the upper edges of the uppermost louvers and the upper ends of said end plates and is secured to said uppermost louvers.

Claim 5

A panel adapted to be assembled end to end with other similar panels to form a polygonal housing wherein at least certain pairs of such panels form angles of a polygon, comprising a pair of upright end plates, a plurality of parallel, spaced louvers extending between said end plates and fixedly secured thereto, and a baseplate secured to and extending between said end plates beneath said louvers, the end plate at each end of the panel being disposed in a plane extending in a direction such that it forms an angle with respect to the general plane of the panel equal to one-half the angle formed by the panel with the next adjacent panel.

Claim 6

A panel adapted to be assembled end to end with other similar panels to form a polygonal housing wherein at least certain pairs of such panels form angles of a polygon, comprising a pair of upright end plates, a plurality of parallel, spaced louvers extending between said end plates and fixedly secured thereto, and a baseplate secured to and extending between said end plates beneath said louvers, the end plate at each end of the panel being disposed in a plane extending in a direction such that it forms an angle with respect to the general plane of the panel equal to one-half the angle formed by the panel with the next adjacent panel.

Claim 7

The panel set forth in claim 4 in which at least one end plate of said panel is in a plane extending at an angle of 45* to the general plane of the panel.

Claim 8

A panel adapted to be assembled end to end with other similar panels to form a polygonal housing wherein at least certain pairs of such panels form angles of a polygon, comprising a pair of upright end plates each having a slot in its rear edge adjacent but above its lower edge, a plurality of parallel, spaced louvers extending between said end plates and fixedly secured thereto, and a baseplate secured to and extending between sAid end plates beneath said louvers, said baseplate having an upwardly extending wall at its rear edge portion having a forwardly projecting flange thereon adapted to be received in the slots of said end plate, the end plate at each end of the panel being disposed in a plane extending in a direction such that it forms an angle with respect to the general plane of the panel equal to one-half the angle formed by the panel with the next adjacent panel.

Claim 9

A panel adapted to be assembled end to end with other similar panels to form a polygonal housing wherein at least certain pairs of such panels form angles of a polygon, comprising a pair of upright end plates each having a slot in its rear edge adjacent but above its lower edge, a plurality of parallel, spaced louvers extending between said end plates and fixedly secured thereto, and a baseplate secured to and extending between sAid end plates beneath said louvers, said baseplate having an upwardly extending wall at its rear edge portion having a forwardly projecting flange thereon adapted to be received in the slots of said end plate, the end plate at each end of the panel being disposed in a plane extending in a direction such that it forms an angle with respect to the general plane of the panel equal to one-half the angle formed by the panel with the next adjacent panel.

Claim 10

A polygonal ventilator housing structure adapted for shipment to the installation site in disassembled condition and adapted for ease of assembly at the installation site, there being required no separate vertical structural support elements, comprising: a. a plurality of side panels each comprising a pair of end plates with a plurality of parallel spaced louvers extending therebetween and fixed thereto, said end plates being adapted to directly abut with the end plates of the next adjacent panels and being disposed relative to the general planes of their respective panels at an angle equal to one-half the angle formed by the general planes of the abutting adjacent panels, and b. fastening means securing the end plate of one panel directly to the abutting end plate of the next adjacent panel.

Claim 11

A polygonal ventilator housing structure adapted for shipment to the installation site in disassembled condition and adapted for ease of assembly at the installation site, there being required no separate vertical structural support elements, comprising: a. a plurality of side panels each comprising a pair of end plates with a plurality of parallel spaced louvers extending therebetween and fixed thereto, said end plates being adapted to directly abut with the end plates of the next adjacent panels and being disposed relative to the general planes of their respective panels at an angle equal to one-half the angle formed by the general planes of the abutting adjacent panels, and b. fastening means securing the end plate of one panel directly to the abutting end plate of the next adjacent panel.

Claim 12

The ventilator housing set forth in claim 6 in which a cover having depending marginal flanges is supported on the upper edges of the uppermost louver of each panel and the upper ends of said end plates, and in which means is provided for securing said cover to said side panels.

Claim 13

The ventilator housing set forth in claim 7 in which the means provided for securing said cover to said side panels comprises a plurality of straps secured to the margins of said cover and secured to the uppermost louvers of said panels.

Claim 14

The ventilator housing set forth in claim 7 in which each side panel has a baseplate affixed to and extending between said end plates.

Claim 15

The ventilator housing set forth in claim 6 in which the upper marginal end portion of one of each pair of end plates at each corner has a flange overlying the upper edge of the other end plate of the pair.

Claim 16

The ventilator housing set forth in claim 6 including a baseplate secured to and extending between said end plates beneath said louvers.

Claim 17

The ventilator housing set forth in claim 11 in which each of said end plates is provided with a slot in its rear edge adjacent but above its lower edge, and in which said baseplate has an upwardly extending wall at its rear edge portion having a forwardly projecting flange thereon received in the slots of said end plates.
