Abstract
Abstract A viewing device in which successive cards of a series are removed from one end of a stack or supply and deposited at the end of the same or another stack or supply and a transfer mechanism for indexing such cards one at a time such that on every other transfer or given number of transfers, the illustration shown, respectively, by any two or corresponding given number of adjacent stacks is completely changed. The cards are peculiarly constructed to cooperate with the transfer mechanism and to maintain the correct sequence of such cards within the stacks.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
175 words
A skip frame viewing device comprising: a frame havIng top, bottom, front and rear wall sections connected together; a plurality of folded information bearing cards disposed within said frame, each of said folded cards having vertical edge portions and furthermore being vertically supported on their respective end portions in at least two side-by-side stacks, said folded cards within each of said respective stacks exerting a pressure against each other and said frame thus maintaining said cards in their respective stacks, means in said frame for dividing said stacks and normally maintaining the cards of each stack aligned with all the other cards in each of said stacks; and indexing means for engaging said edge portions of cooperating end cards and for sliding said cooperating cards individually in a predetermined sequence from the end of one stack to the corresponding end of an adjacent stack, whereby a completely new piece of information depicted by the end cards in adjacent stacks is formed and displayed upon each transfer of two cards from one stack to the other.
Claim 2
Dependent Claim
175 words
A skip frame viewing device comprising: a frame havIng top, bottom, front and rear wall sections connected together; a plurality of folded information bearing cards disposed within said frame, each of said folded cards having vertical edge portions and furthermore being vertically supported on their respective end portions in at least two side-by-side stacks, said folded cards within each of said respective stacks exerting a pressure against each other and said frame thus maintaining said cards in their respective stacks, means in said frame for dividing said stacks and normally maintaining the cards of each stack aligned with all the other cards in each of said stacks; and indexing means for engaging said edge portions of cooperating end cards and for sliding said cooperating cards individually in a predetermined sequence from the end of one stack to the corresponding end of an adjacent stack, whereby a completely new piece of information depicted by the end cards in adjacent stacks is formed and displayed upon each transfer of two cards from one stack to the other.
Claim 3
Dependent Claim
39 words
A device according to claim 1 wherein said front and rear wall sections of said frame comprise front and rear viewing openings having top and bottom edges for permitting the end cards of said stacks to be viewed simultaneously.
Claim 4
Dependent Claim
143 words
A device according to claim 2 wherein said dividing means comprises: vertically aligned divider elements secured to the top and bottom wall sections of said frame and disposed between said front and rear wall sections and in contacting relation with the front and rear wall sections each of said stacks being positioned adjacent one of said vertically aligned divider elements and further vertically aligned divider elements secured to the top and bottom sections of said frame and disposed between said front and rear wall sections in spaced relation from said front and rear wall sections a distance substantially equal to the thickness of one of said information-bearing cards; said divider and said further divider elements having a vertical dimension less than the distance between the top and bottom of the viewing openings and the top and bottom wall section, respectively, of the frame.
Claim 5
Dependent Claim
35 words
A device according to claim 3 wherein said divider elements all are disposed obliquely between said front and rear wall sections for providing slanted stacks therein and thereby eliminating the passage of light between stacks.
Claim 6
Dependent Claim
125 words
A device according to claim 1 wherein said indexing means comprises a member reciprocably disposed in said frame in a direction transverse to said stacks and a pair of indexing tabs on said reciprocably disposed member for each pair of adjacent stacks, one of said tabs being adapted to engage the end card on one side of one stack only for transferring said card to the other stack upon movement of said indexing means in one direction, the other of said tabs being adapted to engage the end card on the other side of the other stack in said adjacent pair of stacks for transferring said card to the first stack upon movement of said indexing means in a direction opposite to said one direction
Claim 7
Dependent Claim
40 words
A device according to claim 5, further comprising additional means on said frame for engaging at least one of said end cards in each of said stacks for preventing said cards from being transferred during movement of said transferring means.
Claim 8
Dependent Claim
38 words
A device according to claim 6 wherein said card indexing means further comprise a pair of rounded projections on said reciprocably disposed member for each pair of adjacent stacks to facilitate compressing of the cards within the stacks.
Claim 9
Dependent Claim
60 words
A device according to claim 1, wherein each of said cards has a C-shaped cross-sectional configuration at least at its top and bottom edges and is formed from at least a single piece of firm, flexible material, the width at its upper and lower edges being smaller than at its intermediate main body area upon which said information is displayed.
Claim 10
Dependent Claim
171 words
A skip frame method of displaying informatiOn comprising the steps of: arranging a plurality of folded cards on edge within a frame in at least two side-by-side stacks, each of said cards having thereon only a portion of a unit of information; compressing said folded cards in each stack to hold the cards in position within the stacks in cooperating relationship with said frame and with end cards of each of said stacks abutting adjacent end cards; displaying the front cards of at least two of said stacks as an uninterrupted unit of information; first sliding a front card by means of a reciprocable element from at least one of said stacks to the front of another of said stacks, whereby portions only of different units of information are displayed; and subsequently transferring another front card from said at least one of said stacks to the front of said another of said stacks by means of said reciprocable element, whereby a complete new unit of uninterrupted information is formed and displayed.
Claim 11
Dependent Claim
171 words
A skip frame method of displaying informatiOn comprising the steps of: arranging a plurality of folded cards on edge within a frame in at least two side-by-side stacks, each of said cards having thereon only a portion of a unit of information; compressing said folded cards in each stack to hold the cards in position within the stacks in cooperating relationship with said frame and with end cards of each of said stacks abutting adjacent end cards; displaying the front cards of at least two of said stacks as an uninterrupted unit of information; first sliding a front card by means of a reciprocable element from at least one of said stacks to the front of another of said stacks, whereby portions only of different units of information are displayed; and subsequently transferring another front card from said at least one of said stacks to the front of said another of said stacks by means of said reciprocable element, whereby a complete new unit of uninterrupted information is formed and displayed.
Claim 12
Dependent Claim
64 words
A method according to claim 9 comprising the further steps of: sliding the backmost card from said another of said stacks to the back of said at least one of said stacks following said first sliding operation and sliding another back panel from said another of said stacks to the back of said at least one of said stacks following said subsequent sliding operation.
Claim 13
Dependent Claim
26 words
A method according to claim 10 further comprising: displaying the back cards of at least two of said stacks for forming an uninterrupted unit of information.
