Abstract
Abstract A demountable-pluggable ribbon cartridge having self-contained adjustable tensioning and re-inking means is provided with a plurality of ribbon inking rollers operable in conjunction with an inking tension roller and a demountable impact receiving printing matrix, the cartridge being removably attachably engagable with the frame of an associated piece of apparatus such that the printing device is operably disposed adjacent to a reciprocably movable anvil, the adjustable self-tensioning means of the cartridge serving to hold the ribbon in a taut state in a printing position adjacent to the anvil and over the face of the printing matrix and to hold the ribbon in frictional contact with cylindrical re-inking members carrying on their peripheries a deformable porous pen-inked foam material. The inked ribbon in the form of an endless loop is movably disposed within an interior peripheral portion of the cartridge, the self-tensioning means comprising an opposing pair of members having discontinuous confronting surface portions between which the ribbon is moved.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A demountable continuous re-inking ribbon cartridge comprising: a base support member, a signature plate holder including means demountably receiving a signature plate having an impression producing area thereon operably associated therewith so that said signature plate can be replaced at will, a continuous ribbon for inking said signature plate, means for continuously inking said ribbon, said inking means being physically arranged to entrap said ribbon constraining the ribbon against lateral movement, and braking means for said ribbon, including means for maintaining said ribbon in taut condition over the impression producing area of said signature plate whereby said ribbon is caused to weave back and forth prior to entering the impression producing area effectively regulating the tautness of the ribbon.
Claim 2
Dependent Claim
119 words
A demountable continuous re-inking ribbon cartridge comprising: a base support member, a signature plate holder including means demountably receiving a signature plate having an impression producing area thereon operably associated therewith so that said signature plate can be replaced at will, a continuous ribbon for inking said signature plate, means for continuously inking said ribbon, said inking means being physically arranged to entrap said ribbon constraining the ribbon against lateral movement, and braking means for said ribbon, including means for maintaining said ribbon in taut condition over the impression producing area of said signature plate whereby said ribbon is caused to weave back and forth prior to entering the impression producing area effectively regulating the tautness of the ribbon.
Claim 3
Dependent Claim
119 words
A demountable continuous re-inking ribbon cartridge comprising: a base support member, a signature plate holder including means demountably receiving a signature plate having an impression producing area thereon operably associated therewith so that said signature plate can be replaced at will, a continuous ribbon for inking said signature plate, means for continuously inking said ribbon, said inking means being physically arranged to entrap said ribbon constraining the ribbon against lateral movement, and braking means for said ribbon, including means for maintaining said ribbon in taut condition over the impression producing area of said signature plate whereby said ribbon is caused to weave back and forth prior to entering the impression producing area effectively regulating the tautness of the ribbon.
Claim 4
Dependent Claim
119 words
A demountable continuous re-inking ribbon cartridge comprising: a base support member, a signature plate holder including means demountably receiving a signature plate having an impression producing area thereon operably associated therewith so that said signature plate can be replaced at will, a continuous ribbon for inking said signature plate, means for continuously inking said ribbon, said inking means being physically arranged to entrap said ribbon constraining the ribbon against lateral movement, and braking means for said ribbon, including means for maintaining said ribbon in taut condition over the impression producing area of said signature plate whereby said ribbon is caused to weave back and forth prior to entering the impression producing area effectively regulating the tautness of the ribbon.
Claim 5
Dependent Claim
39 words
The invention of claim 1 wherein said means demountable receiving said signature plate includes oppositely disposed slidably engagable clamp members operably interengagable with supporting projections enabling said signature plate to be mounted and removed from said cartridge at will.
Claim 6
Dependent Claim
21 words
The invention of claim 1 wherein said braking means includes demountable adjustable members forming an irregular, non-linear pathway for said ribbon.
Claim 7
Dependent Claim
47 words
The invention of claim 1 wherein said means for continuously inking said ribbon includes a triangular cluster of three inking members with one of said inking members being pivotally biased toward the other two inking members to supply tension to the ribbon as the ribbon passes thereover.
Claim 8
Dependent Claim
45 words
The invention of claim 4 wherein said cluster of inking members is arranged with two of said inking members angularly offset relative to each other presenting oppositely angled surfaces to said ribbon thereby constraining said ribbon against lateral movement parallel to said offset inking members.
Claim 9
Dependent Claim
25 words
The invention of claim 1 wherein said braking means comprises oppositely disposed rigid members having irregularly shaped confronting surfaces to provide a ribbon gap opening.
Claim 10
Dependent Claim
51 words
The invention of claim 6 wherein said rigid members are adjustable relative to one another to vary the opening therebetween thus to vary the ribbon gap therebetween and wherein said irregularly shaped confronting surfaces comprise nesting lands and grooves for constraining the ribbon thereby braking the passage of the ribbon therebetween.
Claim 11
Dependent Claim
41 words
The invention of claim 1 wherein said continuous re-inking ribbon cartridge is provided with interengagable self-supporting means in press fit relationship with stud means the base support member with which the cartridge is associated for maintaining said cartridge in printing position.
Claim 12
Dependent Claim
34 words
The invention in accordance with claim 8 where said interengagably self-supporting means includes at least two oppositely disposed orifices, each orifice having a circular groove for receiving said stud means in telescoping relationship therewith.
