Apparatus for producing simulated snow effects
摘要:
An apparatus for producing simulated snow effects for theatrical environments. To create simulated snow in the quantities and qualities necessary for theatrical effects, ice is used as the source material. A plurality of storage channels are adapted for holding and channeling blocks of ice to the snow creating member. A rotating disc incorporates a plurality of radially directed, adjustable cutting blades mounted in the surface of the disc. The disc is rotatable beneath each of the ice supply channels. Each of the cutting blades is pivotable along one radial edge thereof, the angular position of the blade relative to the surface of the disc determining the thickness of the layer of ice shaved from the surface of the ice block in contact therewith. Immediately forwardly of each ice cutting blade is an aperture disposed in the disc to provide a downwardly directed fluid force to the shaved ice. When elevated, shavings or flakes of ice having a selectable thickness from 0.005-0.030 inches may be distributable over an area in excess of 2,000 square feet.
