Total Claims: 10
Claim 1
Independent Claim
211 words
A printing cartridge assembly for use in a lettering machine having a printing station, said printing cartridge assembly containing a tape supply and a printing ribbon supply, said lettering machine causing said ribbon supply to print upon said tape supply, said printing cartridge, comprising: (a) a first housing member; (b) a spool of said tape rotatably mounted within and generally enclosed by said first housing member; (c) a second housing member; (d) a spool of said printing ribbon rotatably mounted within and generally enclosed by said second housing member; (e) guide means projecting outwardly from both said first and second housing members; and (f) means to enable said ribbon supply to be replaced by a ribbon supply of a different color, said last mentioned means including means for releasably attaching said first housing member to said second housing member so that said second housing member can be replaced with a new second housing member containing a ribbon of a different color, the guide means associated with said first and second housing members orienting said tape and ribbon exiting from said first and second housing members in a face-to-face relationship so that upon entry into said print station of said lettering machine said ribbon can be used to print upon said tape.
Claim 2
Dependent Claim
211 words
A printing cartridge assembly for use in a lettering machine having a printing station, said printing cartridge assembly containing a tape supply and a printing ribbon supply, said lettering machine causing said ribbon supply to print upon said tape supply, said printing cartridge, comprising: (a) a first housing member; (b) a spool of said tape rotatably mounted within and generally enclosed by said first housing member; (c) a second housing member; (d) a spool of said printing ribbon rotatably mounted within and generally enclosed by said second housing member; (e) guide means projecting outwardly from both said first and second housing members; and (f) means to enable said ribbon supply to be replaced by a ribbon supply of a different color, said last mentioned means including means for releasably attaching said first housing member to said second housing member so that said second housing member can be replaced with a new second housing member containing a ribbon of a different color, the guide means associated with said first and second housing members orienting said tape and ribbon exiting from said first and second housing members in a face-to-face relationship so that upon entry into said print station of said lettering machine said ribbon can be used to print upon said tape.
Claim 3
Dependent Claim
74 words
The printing cartridge assembly as in claim 1 wherein said first housing member comprises: (a) a pair of generally bilaterally symmetrical molded plastic segments, each having a side wall and an edge wall extending perpendicularly from said side wall about at least a portion of the periphery of said side wall; and (b) means for joining the edge walls of said pair of segments together along a midline to define a generally closed container.
Claim 4
Dependent Claim
31 words
The printing cartridge assembly as in claim 2 and further including a cylindrical projection extending perpendicularly from one of said side walls upon which said spool of tape is rotatably mounted.
Claim 5
Dependent Claim
54 words
The printing cartridge as in claim 3 wherein the side walls and edge walls of said pair of segments are generally circularly curved over a predetermined portion of their periphery, with the center of said circularly curved portion being at the point at which said cylindrical projection extends from one of said side walls.
Claim 6
Dependent Claim
61 words
The printing cartridge assembly as in claim 4 and further including an arcuate surface joined to at least one of said side walls of said pair of molded plastic segments and extending normally from said side wall in the same direction as said edge walls with said arcuate surface forming a continuation of said circularly curved portion of said edge walls.
Claim 7
Dependent Claim
59 words
The printing cartridge as in claim 2 wherein said guide means associated with said first housing member comprises: (b) an elongated member integrally joined to each of said pair of molded plastic segments and projecting outwardly from said edge wall to define a tape travel path from said first housing member toward said printing station of said lettering machine.
Claim 8
Dependent Claim
74 words
The printing cartridge as in claim 1 wherein said second housing member comprises: (a) a pair of molded plastic parts, each having a side wall and an edge wall extending normally from said side wall along a predetermined portion of the periphery of said edge wall; (b) means for joining the edge walls of said molded plastic parts together along a midline to define a generally closed container for said spool of printing ribbon.
Claim 9
Dependent Claim
65 words
The printing cartridge as in claim 7 wherein said guide means associated with said second housing member comprises an elongated member integrally joined to each of said pair of molded plastic parts and forming an extension of said edge walls of said second housing member to define a printing ribbon travel path from said second housing member towards said printing station of said lettering machine.
