Abstract
Abstract A novelty display device which simulates a snow fall. The device includes a base having a transparent container positioned on its top which forms a substantially closed chamber. An electric motor is contained within the base and rotatably drives a fan blade contained within and adjacent bottom of the chamber. Lightweight particulate matter is disposed within the interior of the chamber so that, upon actuation of the fan blade, the fan blade inducts the particulate matter from the bottom of the chamber and circulates the particulate matter throughout the chamber thereby simulating a snowfall.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
A display device comprising: a base having a top, a container positioned on said base top, said container being constructed of a transparent material and forming a substantially closed and air containing chamber, a fan blade contained within said chamber adjacent the bottom of said chamber, means for rotatably driving said fan blade, and light weight particulate matter contained within said chamber so that, upon rotation of said fan blade, said fan blade circulates said particulate matter through said air within said chamber thereby simulating a snowfall, a display figure secured to said rotatable driving means, wherein said display figure has two sides and comprising letter indicia on both sides of said display figure, said letter indicia being such that the letter indicia on both sides of said display figure together form at least one recognizable word while the letter indicia on a single side of said display figure does not form a recognizable word wherein said rotatable driving means alternately displays said sides of said display figure at a sufficiently high speed to form a recognizable word.
Claim 2
Dependent Claim
178 words
A display device comprising: a base having a top, a container positioned on said base top, said container being constructed of a transparent material and forming a substantially closed and air containing chamber, a fan blade contained within said chamber adjacent the bottom of said chamber, means for rotatably driving said fan blade, and light weight particulate matter contained within said chamber so that, upon rotation of said fan blade, said fan blade circulates said particulate matter through said air within said chamber thereby simulating a snowfall, a display figure secured to said rotatable driving means, wherein said display figure has two sides and comprising letter indicia on both sides of said display figure, said letter indicia being such that the letter indicia on both sides of said display figure together form at least one recognizable word while the letter indicia on a single side of said display figure does not form a recognizable word wherein said rotatable driving means alternately displays said sides of said display figure at a sufficiently high speed to form a recognizable word.
