Appurtenance for building vents

Abstract

An improved cover for an outlet intended to exhaust gases from a building to the atmosphere and particularly for chimneys intended to exhaust the products of combustion and for vents intended to exhaust ventilating air from within a building. The cover prevents precipitation as rain, sleet and snow from entering into the outlet while allowing the exhaust gases to rise away from the building in a vertical column essentially unimpeded.

1 . Means intended for fitting on the outlet of a building venting conduit which building venting conduit is intended to exhaust gases from within a building and which means presents essentially insignificant resistance to the upward flow of said gases from said building vent conduit to atmosphere while simultaneously preventing the entrance of precipitation into said building conduit. 
   
   
       2 . Means intended for fitting on the outlet of a building venting conduit which building venting conduit is intended to exhaust gases from within the building and which means both prevents the entrance of precipitation into said building venting conduit while simultaneously presenting essentially insignificant resistance to the flow of said gases thereby allowing said gases to rise upward and away from the building in an essentially undisturbed column. 
   
   
       3 . A chimney cap intended for fitting on a chimney flue that prevents the undesirable entrance of precipitation into the interior of said chimney flue while simultaneously presenting little resistance to the upward flow of exhaust gases from said chimney thereby allowing said gases to continue flowing in an upward direction in the form of an undisturbed column. 
   
   
       4 . A vent cap for a building exhaust vent which vent cap prevents precipitation from entering into the vent while simultaneously allowing upward flowing gases to exhaust essentially unimpeded and which vent cap allows a low profile to the end section of the exhaust vent. 
   
   
       5 . A chimney cap intended for fitting on a chimney flue which chimney cap consists of a combination of members that are arranged so as to trap precipitation and direct said precipitation to a location outside the chimney flue while at the same time allowing rising gases to pass through the chimney cap with little resistance to the flow of the exhaust gases from the chimney flue to atmosphere thereby allowing the gases to continue on an upward path as an essentially undisturbed column. 
   
   
       6 . A vent cap for a building exhaust vent which vent cap consists of a combination of members that are arranged so as to trap precipitation and direct said precipitation to a location outside the vent while at the same time allowing rising gases to rise vertically through the vent cap with little resistance to the flow of exhaust gases from said vent to atmosphere, said vent cap thereby allowing a low profile to the vent cap.
