The venting means includes at least one pair of vent openings, one for air to enter the airspace and one for air to exit. These vent openings include a path through the frame holding the protective panel to an interior opening which is to the airspace. The vent openings, the paths and the interior openings must be of adequate size to minimize the range of temperature and moisture within the airspace. It is recommended that effective vent openings are at least one square inch for every 2000-2500 square inches of ornamental window. ## Claims ### Claim 1 An apparatus for venting ornamental windows covered by a protective panel comprising: a) stained glass window;

b) a protective panel; c) a framing element; d) at least one airspace between said window and said protective panel; e) venting means comprising a plurality of pairs of vent openings each said pair positioned in a vertical portion of said framing element with an exit vent opening spaced vertically above an entry vent opening, said entry vent opening directly to air outside the apparatus having a first area and said exit vent opening directly to air outside the apparatus having a second area; f) each said entry vent opening comprises a first path causing a first directional turn upwards and a first interior opening spaced vertically above said entry vent opening and causing a second directional turn in a horizontal direction and each said exit vent opening comprises a second interior opening causing a directional turn and a second path causing a directional turn; and g) for each said entry vent opening, said first interior opening comprises a third area and for each said exit vent opening, each said second interior opening comprises a fourth area, each said first path comprises a first cross-sectional area and each said second path comprises a second cross-sectional area. ### Claim 7 (depends on 6) The apparatus for venting ornamental windows as claimed in claim 6 wherein for each said entry vent opening, said first area at least equals first cross sectional area and said first cross sectional area does not exceed said third area and a sum of all said first areas is at least one square inch for every 2000-2500 square inches of ornamental window for facilitating adequate rate and volume of airflow. ### Claim 8 (depends on 7) An apparatus for venting ornamental windows as claimed in claim 7 wherein for each said exit vent opening, said fourth area at least equals said second cross sectional area and said second cross sectional area does not exceed said second area. ### Claim 9 An apparatus for venting ornamental windows covered by a protective panel comprising: a) a stained glass window; b) a protective panel; c) at least one framing element; d) at least one airspace between said window and said protective panel; e) venting means comprising at least one pair of vent openings each pair comprising an entry vent opening having a first area and an exit vent opening having a second area and spaced vertically above said entry vent opening; f) each said entry vent opening comprises a first proximal path causing a first directional turn upwards and having a first proximal cross section, a first inside opening causing a second directional turn in a horizontal direction, a first distal path having a first distal cross section and a first interior opening vertically spaced above said entry vent opening all for allowing air to flow into said airspace and each said exit vent opening comprises a second proximal path causing a first directional turn and having a second proximal cross section, a second inside opening causing a second directional turn, a second distal path having a second distal cross section and a second interior opening vertically spaced below said exit vent opening all for allowing air to flow out of said airspace; g) said first interior opening comprises a third area and said second interior opening comprises a fourth area; h) said first inside opening comprises a fifth area and said second inside opening comprises a sixth area; i) for each said entry vent opening, said first area does not exceed said first proximal cross sectional area, said fifth area at least equals said first proximal cross sectional area, said first distal cross sectional area at least equals said fifth area, and said third area at least equals said first distal cross sectional area; and j) for each said exit vent opening, said fourth area does not exceed said second distal cross sectional area, said sixth area at least equals said second distal cross sectional area, said second proximal cross sectional area at least equals said sixth area and said second area at least equals said second proximal cross sectional area for facilitating adequate rate and volume of flow to minimize the effects of extreme temperatures and of bacterial damage. ### Claim 10 (depends on 9) The apparatus for venting ornamental windows as claimed in claim 9 wherein at least one dam member is positioned to direct airflow from each said entry vent opening to each said first path. ### Claim 11 (depends on 9) The apparatus for venting ornamental windows as claimed in claim 9 wherein at least one said framing element is a first casting having at least one said entry vent opening and another at least one said framing element is a second casting having at least one said exit vent opening. ### Claim 12 (depends on 9) The apparatus for venting ornamental windows as claimed in claim 9 wherein said at least one framing element is a total frame which holds both said protective panel and said ornamental window. ### Claim 13 (depends on 9) The apparatus for venting ornamental windows as claimed in claim 9 wherein said at least one framing element is a perimeter frame which holds only said protective panel and said airspace is defined by a separation between said protective panel and said ornamental window. ### Claim 14 (depends on 13) The apparatus for venting ornamental windows as claimed in claim 13 wherein said venting means further comprises a first casting having at least one said entry vent opening and a second casting having at least one said exit vent opening. ### Claim 15 (depends on 13) The apparatus for venting ornamental windows as claimed in claim 13 wherein at least one dam member is positioned to direct airflow from each said entry vent opening to each said first path. ### Claim 16 (depends on 13) The apparatus for venting ornamental windows as claimed in claim 13 wherein at least one of said entry vent openings includes a debris deterring accessory. ### Claim 17 (depends on 13) The apparatus for venting ornamental windows as claimed in claim 13 further comprising at least one hood positioned proximal one of said entry vent opening for deterring entry of debris. ### Claim 18 (depends on 13) The apparatus for venting ornamental windows as claimed in claim 13 further comprising at least one screen proximal one of said entry vent opening for deterring entry of debris. ### Claim 19 (depends on 9) The apparatus for venting ornamental windows as claimed in claim 9 wherein at least one of said entry vent openings includes a debris deterring accessory. ### Claim 20 (depends on 19) The apparatus for venting ornamental windows as claimed in claim 19 wherein said debris deterring accessory is a screen. ### Claim 21 (depends on 19) The apparatus for venting ornamental windows as claimed in claim 19 wherein said debris deterring accessory is a hood.
