Tornado device

Claim 2

Apparatus for creating a contained visible tornado comprising: a structure having walls means defining a chamber, an opening in a top Portion of said wall means facing generally along an axis extending to an opposite wall of said chamber and said opening communicating with power driven exhaust means for drawing air therethrough from said chamber, another opening in a side portion of said wall means for admitting air into said chamber when air is removed through said first-mentioned opening, said another opening admitting air into said chamber in a direction tangentially of said axis whereby air entering said chamber is drawn into a tight spiral helix motion defining a vortex generally about said axis and rising upwardly toward said exhaust opening, means for inducing in said chamber a substance visible in air at a location remote from said first mentioned opening for visibly marking said vortex.

Claim 3

The claims subject matter of claim 1 wherein said exhaust opening is located on the top of said chamber and said inlet opening is located on a side of said chamber.

Claim 4

The claimed subject matter of claim 2 wherein said axis is generally vertically disposed.

Claim 5

The claimed subject matter of claim 3 wherein the inlet opening may be varied.

Claim 6

Apparatus for creating a contained visible tornado comprising: a chamber defined by walls, ceiling and floor, an exhaust opening in the ceiling communicating with a power air exhaust system for removal of air from the chamber, a vertical inlet opening in one of the walls for admitting air into the chamber, said exhaust opening facing into the chamber generally along a vertical axis extending substantially to the floor, said inlet opening facing horizontally for admitting air of the vertical axis so that the air drawn into the chambers is in spiral motion which terminates in a tight rising helical vortex column resembling a tornado, a substance visible in air introduced into said chamber adjacent the floor for identifying said vortex.

Claim 7

Apparatus for creating a contained visible tornado comprising: a chamber defined by walls, ceiling and floor, an exhaust opening in the ceiling communicating with a power air exhaust system for removal of air from the chamber, a vertical inlet opening in one of the walls for admitting air into the chamber, said exhaust opening facing into the chamber generally along a vertical axis extending substantially to the floor, said inlet opening facing horizontally for admitting air of the vertical axis so that the air drawn into the chambers is in spiral motion which terminates in a tight rising helical vortex column resembling a tornado, a substance visible in air introduced into said chamber adjacent the floor for identifying said vortex.

Claim 8

Apparatus for creating a contained visible simulated tornado comprising: wall means enclosing the top, side and bottom of an empty chamber, an opening in the top wall facing downwardly along an axis extending generally uninterrupted to the bottom wall and generally centrally of the sidewalls, power driven air exhaust means in communication with the opening in the top wall for removing air therethrough from said chamber, an opening in the side wall extending a substantial portion of the height thereof and facing in a direction to one side of said axis whereby air in being drawn therethrough to said chamber in response to air being drawn from said chamber by said exhaust means is drawn cyclonically into said chamber and into a helical-spiral vortex about said axis and exhausted through the opening in the top wall, means for introducing a substance visible in air above the bottom as an aid in identifying said vortex.

Claim 9

Apparatus for creating a contained visible simulated tornado comprising: wall means enclosing the top, side and bottom of an empty chamber, an opening in the top wall facing downwardly along an axis extending generally uninterrupted to the bottom wall and generally centrally of the sidewalls, power driven air exhaust means in communication with the opening in the top wall for removing air therethrough from said chamber, an opening in the side wall extending a substantial portion of the height thereof and facing in a direction to one side of said axis whereby air in being drawn therethrough to said chamber in response to air being drawn from said chamber by said exhaust means is drawn cyclonically into said chamber and into a helical-spiral vortex about said axis and exhausted through the opening in the top wall, means for introducing a substance visible in air above the bottom as an aid in identifying said vortex.

Claim 10

The claimed subject matter of claim 6 further defined by said sidewall opening so located in the sidewall that a portion of the sidewall defines a surface for guiding entering air into cyclonic motion about said axis.
