Claim 1
Independent Claim
249 words
Printing apparatus comprising: a print bed; a carriage having at least two rollers disposed at opposite sides thereof and cooperating with opposite sides of said printing apparatus for movement of said carriage over said print bed; a roller platen; means loosely connected between said carriage and said roller platen for moving said roller platen whenever said carriage is moved; first and second channels respectively disposed at two sides of said printing apparatus; first and second roller pairs respectively disposed and connected to opposite ends of said roller platen and respectively disposed within said first and second channels, one of said rollers of said first roller pair being connected to one of the rollers of said second roller pair and the other roller of said first roller pair being connected to the other roller of said second roller pair; first and second flexible bands respectively disposed within said first and second channels, each band being coNnected at one end of said printing apparatus at the top of its associated channel and at the other end thereof at the bottom of its associated channel and each band passing from its connection at said one end of the imprinting apparatus over and around one roller of its associated roller pair and then around and under the other roller of its associated roller pair and thence to said connection at the other end of said printing apparatus; and whereby an imprint is created whenever said roller platen is moved across said print bed.
Claim 2
Dependent Claim
249 words
Printing apparatus comprising: a print bed; a carriage having at least two rollers disposed at opposite sides thereof and cooperating with opposite sides of said printing apparatus for movement of said carriage over said print bed; a roller platen; means loosely connected between said carriage and said roller platen for moving said roller platen whenever said carriage is moved; first and second channels respectively disposed at two sides of said printing apparatus; first and second roller pairs respectively disposed and connected to opposite ends of said roller platen and respectively disposed within said first and second channels, one of said rollers of said first roller pair being connected to one of the rollers of said second roller pair and the other roller of said first roller pair being connected to the other roller of said second roller pair; first and second flexible bands respectively disposed within said first and second channels, each band being coNnected at one end of said printing apparatus at the top of its associated channel and at the other end thereof at the bottom of its associated channel and each band passing from its connection at said one end of the imprinting apparatus over and around one roller of its associated roller pair and then around and under the other roller of its associated roller pair and thence to said connection at the other end of said printing apparatus; and whereby an imprint is created whenever said roller platen is moved across said print bed.
Claim 3
Dependent Claim
56 words
Apparatus as in claim 1 where the bottom of said first and second channels are coplanar with the upper surface of said print bed whereby said first and second bands clamp said document onto said print bed during a printing operation and prevent the removal thereof until the roller platen is returned to an initial position.
Claim 4
Dependent Claim
53 words
Printing apparatus as in claim 1 where said roller platen is a sleeve and said means for moving said roller platen includes a shaft disposed within said sleeve and connected between vertical legs of said carriage, said shaft engaging the inner surface of said sleeve whenever the motion is imparted to said carriage.
Claim 5
Dependent Claim
16 words
Apparatus as in claim 3 where said shaft is rotatably mounted with respect to said carriage.
Claim 6
Dependent Claim
21 words
Apparatus as in claim 4 where the inner diameter of said sleeve is approximately 2 times the diameter of said shaft.
Claim 7
Dependent Claim
38 words
Apparatus as in claim 1 where said first and second bands are respectively movably connected with respect to said one end of said imprinting apparatus whereby variations in thicknesses of documents, printing plates and/or embossings may be compensated.
Claim 8
Dependent Claim
26 words
Apparatus as in claim 6 including two springs respectively connected between the ends of said bands and said one end to thereby effect said movable connection.
Claim 9
Dependent Claim
85 words
Printing apparatus as in claim 1 where said print bed is provided with a recess for receiving a printing plate, the depth of which is greater than the thickness of the printing plate body but less than the total thickness of said plate and where said roller platen is disposed immediately above said print bed whereby only the roller platen and the raised characters coact during a printing operation and not the body of the plate to thereby eliminating smudging originating from the plate body.
Claim 10
Dependent Claim
23 words
Apparatus as in claim 8 where the depth of said recess is approximately 0.005 inch greater than the thickness of said plate body.
Claim 11
Dependent Claim
14 words
Apparatus as in claim 1 including an ink roller disposed about said roller platen.
