Abstract
Abstract An amusement device for producing a variety of unusual changing images, comprising a central, internally transparent member having arcuate means for causing interior reflection extending substantially the entire length of the member. An object supporting member at one end of the central member may contain a multiplicity of small objects, which may be of birefringent material. The eyepiece, disposed at the other end of the chamber, may have a light polarizing viewing surface, and another light polarizing surface may be disposed at the end of the object supporting member remote from the viewing surface. Either or both of the eyepiece and object supporting member may be rotatable relative to the central chamber. The object supporting member may be replaced by a lens for viewing outside objects.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
111 words
An image producing device comprising an elongate hollow member having arcuate internal means for causing interior reflection extending substantially the entire length thereof, light transmitting objective means at one end of said elongate member in light transmitting communication with said interior reflecting means, and viewing means at the other end of said elongate member communicating with said reflecting means, said reflecting means comprising substantially the entire inner surface of said elongate hollow member and being formed of a spirally wound reflective sheet comprising a plurality of turns of said sheet, with each successive turn overlapping at least a portion of the previous turn and being telescoped within the next successive turn.
Claim 2
Dependent Claim
111 words
An image producing device comprising an elongate hollow member having arcuate internal means for causing interior reflection extending substantially the entire length thereof, light transmitting objective means at one end of said elongate member in light transmitting communication with said interior reflecting means, and viewing means at the other end of said elongate member communicating with said reflecting means, said reflecting means comprising substantially the entire inner surface of said elongate hollow member and being formed of a spirally wound reflective sheet comprising a plurality of turns of said sheet, with each successive turn overlapping at least a portion of the previous turn and being telescoped within the next successive turn.
Claim 3
Dependent Claim
79 words
An image producing device comprising an elongate hollow member having arcuate internal means for causing interior reflection extending substantially the entire length thereof, light transmitting objective means at one end of said elongate member in light transmitting communication with said interior reflecting means, and viewing means at the other end of said elongate member communicating with said reflecting means, said interior reflecting means comprising a helically wound reflective sheet, the adjacent convolutions of which are in spaced apart relationship.
Claim 4
Dependent Claim
79 words
An image producing device comprising an elongate hollow member having arcuate internal means for causing interior reflection extending substantially the entire length thereof, light transmitting objective means at one end of said elongate member in light transmitting communication with said interior reflecting means, and viewing means at the other end of said elongate member communicating with said reflecting means, said interior reflecting means comprising a helically wound reflective sheet, the adjacent convolutions of which are in spaced apart relationship.
Claim 5
Dependent Claim
83 words
An image producing device comprising an elongate hollow member having arcuate internal means for causing interior reflection extending substantially the entire length thereof, light transmitting objective means at one end of said elongate member in light transmitting communication with said interior reflecting means, and viewing means at the other end of said elongate member communicating with said reflecting means, said objective means comprising an object supporting member and a plurality of objects of varying size, shape or color within said object supporting member.
Claim 6
Dependent Claim
83 words
An image producing device comprising an elongate hollow member having arcuate internal means for causing interior reflection extending substantially the entire length thereof, light transmitting objective means at one end of said elongate member in light transmitting communication with said interior reflecting means, and viewing means at the other end of said elongate member communicating with said reflecting means, said objective means comprising an object supporting member and a plurality of objects of varying size, shape or color within said object supporting member.
Claim 7
Dependent Claim
51 words
The device of claim 3, wherein at least a portion of said objects are comprised of birefringent material, and said object supporting member includes a translucent sheet of light polarizing material, said viewing means comprises a transparent sheet of light polarizing material, and said birefringent material is between said polarizing sheets.
Claim 8
Dependent Claim
