Abstract

Abstract A hollow cylindrical fluid-tight container is freely carried upon the object end of a kaleidoscope. Vanes within the container serve to agitate the fluid when the container is rotated. Free floating colored members within the fluid form changing patterns as the container is rotated. Illumination for the container is supplied solely by artificial illumination.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 145 words
A kaleidoscope comprising an elongated hollow tubular housing, an eyepiece at one end of the housing, an object space at the opposite end of the housing, a hollow cylindrical fluidtight container having opposed end walls and a cylindrical side wall freely carried within the object space, at least one fin member secured to the inner surface of the said container and extending inwardly thereof, a quantity of fluid within the fluidtight container, a plurality of colored members freely carried within the said container said fin member extending partially into the path of the said colored members, elongated reflective membes carried within the housing between the eyepiece and the fluid-tight container, means to illuminate the interior of the fluid-tight container through the side wall of the container, and means to rotate the said container to activate the colored particles within the container to produce kaleidoscopic displays.
Claim 2
Dependent Claim 145 words
A kaleidoscope comprising an elongated hollow tubular housing, an eyepiece at one end of the housing, an object space at the opposite end of the housing, a hollow cylindrical fluidtight container having opposed end walls and a cylindrical side wall freely carried within the object space, at least one fin member secured to the inner surface of the said container and extending inwardly thereof, a quantity of fluid within the fluidtight container, a plurality of colored members freely carried within the said container said fin member extending partially into the path of the said colored members, elongated reflective membes carried within the housing between the eyepiece and the fluid-tight container, means to illuminate the interior of the fluid-tight container through the side wall of the container, and means to rotate the said container to activate the colored particles within the container to produce kaleidoscopic displays.
Claim 3
Dependent Claim 67 words
A device according to claim 1 in which the housing is carried upon a base, the wall of the housing adjacent the said container is provided with a window, the base adjacent the housing window is provided with an aperture in register with the window and a light means is carried by the base adjacent the said aperture to illuminate the interior of the fluid filled container.
Claim 4
Dependent Claim 64 words
A device according to claim 2 in which the bottom of the fluid-tight container is provided with a stub shaft, a bevel gear is secured to the stub shaft, the base freely supports a transverse shaft and a second bevel gear, in mesh with the container bevel gear, is carried by the transverse shaft, whereby rotation of the transverse shaft will rotate the container.
Claim 5
Dependent Claim 24 words
