Abstract
Abstract A device for displaying and animating a plurality of transparencies in succession. A cabinet is provided with a polarizing light projection means located in its central section and an endless carrier for removing transparencies from a storage section to a viewing window and back to the storage section. A transfer section is provided so that the transparencies may be moved to and from display and storage without interfering with the light projection. Animation is provided by a rotary polarizer, a stationary polarized sheet and transparencies carrying embossed motion lines.

Claim 1
Independent Claim
306 words
An automated device for the successive display of a plurality of transparencies, wherein each transparency is suspended from a supporting rod, said automated device comprising: a cabinet enclosing the transparencies, said cabinet comprising a storage section, a central section having at least one window for viewing, and a transfer section, said sections being arranged one above the other with the central section between the storage and transfer sections; light projection means for projecting light from said central section onto the rear of one of said transparencies for illuminating the transparency in said window; an endless carrier and rod engaging means attached to said carrier for engaging each end of each rod for transporting said rods in a vertical plane past said viewing window and consecutively from said storage section, into said central section, to said transfer section, back to said central section and to said storage section; said rods moving generally horizontally through said storage and transfer sections in a manner such that the transparencies depending therefrom do not interfere with the light passing through said window; means for driving said endless carrier intermittently to position each transparency in said window for a predetermined period of time; an inclined ramp mounted within said storage section, said transparency supporting rods within the storage section being suspended on the upper surface of said inclined ramp; and a camming mechanism, rotatably mounted within said cabinet, for successively lifting said transparency supporting rods from said ramp into position for engagement by said rod engaging means, said camming mechanism comprising a lifting arm, biasing means to retain said lifting arm in a disengaged position, a second arm for engaging an extension provided on said endless carrier, which engagement operates to rotate the lifting arm upward to remove a supporting rod and suspended sheet from said inclined ramp and into said position.
Claim 2
Dependent Claim
306 words
An automated device for the successive display of a plurality of transparencies, wherein each transparency is suspended from a supporting rod, said automated device comprising: a cabinet enclosing the transparencies, said cabinet comprising a storage section, a central section having at least one window for viewing, and a transfer section, said sections being arranged one above the other with the central section between the storage and transfer sections; light projection means for projecting light from said central section onto the rear of one of said transparencies for illuminating the transparency in said window; an endless carrier and rod engaging means attached to said carrier for engaging each end of each rod for transporting said rods in a vertical plane past said viewing window and consecutively from said storage section, into said central section, to said transfer section, back to said central section and to said storage section; said rods moving generally horizontally through said storage and transfer sections in a manner such that the transparencies depending therefrom do not interfere with the light passing through said window; means for driving said endless carrier intermittently to position each transparency in said window for a predetermined period of time; an inclined ramp mounted within said storage section, said transparency supporting rods within the storage section being suspended on the upper surface of said inclined ramp; and a camming mechanism, rotatably mounted within said cabinet, for successively lifting said transparency supporting rods from said ramp into position for engagement by said rod engaging means, said camming mechanism comprising a lifting arm, biasing means to retain said lifting arm in a disengaged position, a second arm for engaging an extension provided on said endless carrier, which engagement operates to rotate the lifting arm upward to remove a supporting rod and suspended sheet from said inclined ramp and into said position.
Claim 3
Dependent Claim
253 words
An automated device for the successive display of a plurality of transparencies, wherein each transparency is suspended from a supporting rod, said automated device comprising: a cabinet enclosing the transparencies, said cabinet comprising a storage section, a central section having at least one window for viewing, and a transfer section, said sections being arranged one above the other with the central section between the storage and transfer sections; light projection means for projecting light from said central section onto the rear of one of said transparencies for illuminating the transparency in said window; an endless carrier and rod holding means attached to said carrier for engaging each end of each rod for transporting said rods in a vErtical plane past said viewing window and consecutively from said storage section, into said central section, to said transfer section, back to said central section and to said storage section; said rods moving generally horizontally through said storage and transfer sections in a manner such that the transparencies depending therefrom do not interfere with the light passing through said window; means for driving said endless carrier intermettently to position each transparency in said window for a predetermined period of time; and an anti-drag device comprising a rotatably mounted lever arm within the path of the supporting rod, said lever arm being rotated by engagement with the rod in such a manner as to cause the lower extremity of said lever arm to force the bottom portion of the suspended transparency toward the interior of the cabinet.
Claim 4
Dependent Claim
253 words
An automated device for the successive display of a plurality of transparencies, wherein each transparency is suspended from a supporting rod, said automated device comprising: a cabinet enclosing the transparencies, said cabinet comprising a storage section, a central section having at least one window for viewing, and a transfer section, said sections being arranged one above the other with the central section between the storage and transfer sections; light projection means for projecting light from said central section onto the rear of one of said transparencies for illuminating the transparency in said window; an endless carrier and rod holding means attached to said carrier for engaging each end of each rod for transporting said rods in a vErtical plane past said viewing window and consecutively from said storage section, into said central section, to said transfer section, back to said central section and to said storage section; said rods moving generally horizontally through said storage and transfer sections in a manner such that the transparencies depending therefrom do not interfere with the light passing through said window; means for driving said endless carrier intermettently to position each transparency in said window for a predetermined period of time; and an anti-drag device comprising a rotatably mounted lever arm within the path of the supporting rod, said lever arm being rotated by engagement with the rod in such a manner as to cause the lower extremity of said lever arm to force the bottom portion of the suspended transparency toward the interior of the cabinet.
Claim 5
Dependent Claim
35 words
The device of claim 2 additionally comprising means adjacent to the approach to said storage section for removal of supporting rods from engagement with said rod holding means and for deposit within said storage section.
Claim 6
Dependent Claim
45 words
The device of claim 2 wherein said rod holding means comprises at least one pair of spaced front and rear hooks attached to said endless carrier for the transport of the transparencies, said pair of hooks being arranged with their openings in a facing relationship.
Claim 7
Dependent Claim
39 words
The device of claim 4 additionally comprising lifting means to successfully lift said transparency supporting rods into the space between said pair of hooks, so that the rear hook engages a supporting rod for movement from said storage section.
Claim 8
Dependent Claim
