Abstract
Abstract Apparatus for mixing air within a room includes a hollow leg section having, at one axial location, a circumferentially extending outlet section. The leg section is disposed in substantially perpendicular relationship to the circumferentially extending outlet section. The apparatus also includes a fan disposed in spaced relation from the lowest extremity of the leg section and oriented to push a gas into the leg section and out the circumferentially extending outlet section. The fan is dimensioned to draw primary air through the fan, the primary air drawing secondary ambient air. A sleeve shaped first member is disposed in spaced relationship to the hollow leg section and in spaced relationship from the circumferentially extending outlet section.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
Apparatus for mixing air within a room, which comprises: a hollow leg section having, at one axial location, a circumferentially extending outlet section, said leg section being disposed in substantially perpendicular relationship to said circumferentially extending outlet section; a sleeve shaped first member disposed (1) in spaced relationship to said hollow leg section and (2) in spaced relationship from said circumferentially extending outlet section; and a fan disposed in axial spaced relation from the lowest extremity of said leg section with an opening to ambient therebetween and oriented to push ambient air into said leg section and out said circumferentially extending outlet section; and said fan being dimensioned to urge primary air through said fan, said sleeve shaped first member including means to cause the primary air to draw secondary ambient air from the room intermediate said sleeve shaped first member and said circumferentially extending outlet section into the room.
Claim 2
Dependent Claim
150 words
Apparatus for mixing air within a room, which comprises: a hollow leg section having, at one axial location, a circumferentially extending outlet section, said leg section being disposed in substantially perpendicular relationship to said circumferentially extending outlet section; a sleeve shaped first member disposed (1) in spaced relationship to said hollow leg section and (2) in spaced relationship from said circumferentially extending outlet section; and a fan disposed in axial spaced relation from the lowest extremity of said leg section with an opening to ambient therebetween and oriented to push ambient air into said leg section and out said circumferentially extending outlet section; and said fan being dimensioned to urge primary air through said fan, said sleeve shaped first member including means to cause the primary air to draw secondary ambient air from the room intermediate said sleeve shaped first member and said circumferentially extending outlet section into the room.
Claim 3
Dependent Claim
20 words
