Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
An indicia display device comprising; (a). a housing having generally front and back panels and having a plurality of apertures (b). a plurality of indicia carrying wheels adapted to fit into the apertures of the front panel comprising; (1) a generally cylindrical body member having at least one closed end, (2) a hub extending through the center of the cylindrical body member, (3) a plurality of grooves in the end surface of the cylindrical body member, and (4) a radial flange attached to one end of the cylindrical body member for manually rotating the cylindrical body member; (c). a set of first retainer arms attached to the front panel of the housing and adapted to receive the hub of the indicia carrying wheels; (d). a set of second retainer arms attached to the back panel of the housing and adapted to receive the hub of the indicia carrying wheels; and (e). a set of index arms attached to the housing adapted to engage the grooves in the end surface of the indicia carrying wheels thereby preventing the wheels from turning freely.
Claim 2
Dependent Claim
181 words
An indicia display device comprising; (a). a housing having generally front and back panels and having a plurality of apertures (b). a plurality of indicia carrying wheels adapted to fit into the apertures of the front panel comprising; (1) a generally cylindrical body member having at least one closed end, (2) a hub extending through the center of the cylindrical body member, (3) a plurality of grooves in the end surface of the cylindrical body member, and (4) a radial flange attached to one end of the cylindrical body member for manually rotating the cylindrical body member; (c). a set of first retainer arms attached to the front panel of the housing and adapted to receive the hub of the indicia carrying wheels; (d). a set of second retainer arms attached to the back panel of the housing and adapted to receive the hub of the indicia carrying wheels; and (e). a set of index arms attached to the housing adapted to engage the grooves in the end surface of the indicia carrying wheels thereby preventing the wheels from turning freely.
Claim 3
Dependent Claim
54 words
That indicia display device claimed in claim 1 wherein the indicia carrying wheels are arranged in rows so that the wheels in the same row have the same axis of rotation and the axis of rotation of any given wheel is at right angles to the axis of rotation of wheels in adjacent rows.
Claim 4
Dependent Claim
192 words
An indicia display device comprising: a. a housing having generally front and back panels and having a plurality of apertures; b. a first set of indicia carrying wheels adapted to fit into the apertures of the front panel comprising: 1. a generally cylindrical body member having at least one closed end, 2. a hub extending through the center of the cylindrical body member, 3. a plurality of grooves in the end surface of the cylindrical body member, and 4. a radial flange attached to one end of the cylindrical body member for manually rotating the cylindrical body member; c. a set of first retainer arms attached to the front panel of the housing and adapted to receive the hub of the first set of indicia carrying wheels; d. a set of second retainer arms attached to the back panel of the housing and adapted to receive the hub of the first set of indicia carrying wheels; e. at least one shaft; f. a second set of indicia carrying wheels adapted to fit into the apertures of the front panel comprising: 1. a generally cylindrical body member having at least one closed end,
Claim 5
Dependent Claim
192 words
An indicia display device comprising: a. a housing having generally front and back panels and having a plurality of apertures; b. a first set of indicia carrying wheels adapted to fit into the apertures of the front panel comprising: 1. a generally cylindrical body member having at least one closed end, 2. a hub extending through the center of the cylindrical body member, 3. a plurality of grooves in the end surface of the cylindrical body member, and 4. a radial flange attached to one end of the cylindrical body member for manually rotating the cylindrical body member; c. a set of first retainer arms attached to the front panel of the housing and adapted to receive the hub of the first set of indicia carrying wheels; d. a set of second retainer arms attached to the back panel of the housing and adapted to receive the hub of the first set of indicia carrying wheels; e. at least one shaft; f. a second set of indicia carrying wheels adapted to fit into the apertures of the front panel comprising: 1. a generally cylindrical body member having at least one closed end,
Claim 6
Dependent Claim
120 words
a hub extending through the center of the cylindrical body member and having a hole therethrough to permit it to be mounted on and rotated about a shaft, 3. a plurality of grooves in the end surface of the cylindrical body member, and 4. a radial flange attached to one end of the cylindrical body member for manually rotating the cylindrical body member, said second set of indicia carrying wheels being mounted on said at least one shaft for rotation about the shaft; and g. a set of index arms attached to the housing adapted to engage the grooves in the end surface of the first and second sets of indicia carrying wheels thereby preventing the wheels from turning freely.
Claim 7
Dependent Claim
120 words
a hub extending through the center of the cylindrical body member and having a hole therethrough to permit it to be mounted on and rotated about a shaft, 3. a plurality of grooves in the end surface of the cylindrical body member, and 4. a radial flange attached to one end of the cylindrical body member for manually rotating the cylindrical body member, said second set of indicia carrying wheels being mounted on said at least one shaft for rotation about the shaft; and g. a set of index arms attached to the housing adapted to engage the grooves in the end surface of the first and second sets of indicia carrying wheels thereby preventing the wheels from turning freely.
