Claim 5

A fire protection system according to claim 2 including: a cover mounted over said crest trough in vertically spaced relation to said trough edges.

Claim 6

A fire protection system for a building structure having sidewalls and a sloping roof with a crest and eaves, comprising a water conduit mounted along said roof crest having outlet means for discharging water onto said roof adjacent said crest, whereby the water flows by gravity downwardly along said roof to said roof eaves, a gutter mounted along said eaves for receiving the water from said roof and having outlet means for discharging the water onto the upper portions of said sidewalls, whereby the water flows by gravity downwardly along said sidewalls, a lower trough extending along the base of said sidewalls for receiving the water flowing downwardly along said sidewalls, and means for recirculating water from said lower trough to said crest conduit.

Claim 7

A fire protection system for a building structure having sidewalls and a sloping roof with a crest and eaves, comprising a water conduit mounted along said roof crest having outlet means for discharging water onto said roof adjacent said crest, whereby the water flows by gravity downwardly along said roof to said roof eaves, a gutter mounted along said eaves for receiving the water from said roof and having outlet means for discharging the water onto the upper portions of said sidewalls, whereby the water flows by gravity downwardly along said sidewalls, a lower trough extending along the base of said sidewalls for receiving the water flowing downwardly along said sidewalls, and means for recirculating water from said lower trough to said crest conduit.

Claim 8

A fire protection system according to claim 4 wherein: said recirculating means comprises a water reservoir, Means for delivering water from said reservoir to said crest conduit, and means for returning water from said lower trough to said reservoir.

Claim 9

A fire protection system for a building structure having sidewalls and a sloping roof with a crest and eaves, comprising: a water conduit mounted along said roof crest having outlet means for discharging water onto said roof adjacent said crest, whereby the water flows by gravity downwardly along said roof to said roof eaves, a gutter mounted along said eaves for receiving the water from said roof and having outlet means for discharging the water onto the upper portions of said sidewalls, whereby the water flows by gravity downwardly along said sidewalls, said eaves project outwardly beyond said sidewalls, and said gutter outlet means comprises a conduit mounted under said eaves adjacent the upper portion of said sidewalls and having outlet means for discharging water onto the upper sidewall portions, and means communicating said latter conduit to said gutter.

Claim 10

A fire protection system for a building structure having sidewalls and a sloping roof with a crest and eaves, comprising: a water conduit mounted along said roof crest having outlet means for discharging water onto said roof adjacent said crest, whereby the water flows by gravity downwardly along said roof to said roof eaves, a gutter mounted along said eaves for receiving the water from said roof and having outlet means for discharging the water onto the upper portions of said sidewalls, whereby the water flows by gravity downwardly along said sidewalls, said eaves project outwardly beyond said sidewalls, and said gutter outlet means comprises a conduit mounted under said eaves adjacent the upper portion of said sidewalls and having outlet means for discharging water onto the upper sidewall portions, and means communicating said latter conduit to said gutter.

Claim 11

A fire protection system according to claim 6 including: a lower trough extending along the base of said sidewalls for receiving the water flowing downwardly along said sidewalls, and means for recirculating water from said lower trough to said crest conduit.

Claim 12

A fire protection system according to claim 7 wherein: said recirculating means comprises a water reservoir, means for delivering water from said reservoir to said crest conduit, and means for returning water from said lower trough to said reservoir.

Claim 13

A fire protection system according to claim 8 wherein: recirculating means comprises a recirculating pump, and said fire protection system further comprises a fire sensor, and means controlled by said detector for starting said pump in response to detection of a fire by said sensor.

Claim 14

A fire protection system for a building structure comprising: a water system for delivering water to the outer surfaces of said building structure, at least one fire sensor located externally of said structure, means controlled by said sensor for activating said water system to wet said structure in response to detection of a fire by said sensor, and said water system comprising a water conduit mounted along said roof crest having outlet means for discharging water onto said roof adjacent said crest, whereby the water flows by gravity downwardly along said roof to said roof eaves, a gutter mounted along said eaves for receiving the water from said roof and having outlet means for discharging the water onto the upper portions of said sidewalls, whereby the water flows by gravity downwardly along said sidewalls, a water reservoir, means for delivering water from said reservoir to said crest conduit, and means for returning water from the lower portions of said building sidewalls to said reservoir.

Claim 15

A fire protection system for a building structure comprising: a water system for delivering water to the outer surfaces of said building structure, at least one fire sensor located externally of said structure, means controlled by said sensor for activating said water system to wet said structure in response to detection of a fire by said sensor, and said water system comprising a water conduit mounted along said roof crest having outlet means for discharging water onto said roof adjacent said crest, whereby the water flows by gravity downwardly along said roof to said roof eaves, a gutter mounted along said eaves for receiving the water from said roof and having outlet means for discharging the water onto the upper portions of said sidewalls, whereby the water flows by gravity downwardly along said sidewalls, a water reservoir, means for delivering water from said reservoir to said crest conduit, and means for returning water from the lower portions of said building sidewalls to said reservoir.
