Abstract
Abstract An intaglio inking plate comprising a printing surface having an aperture therein, a plurality of separately-movable bars filling the aperture and means for positioning each bar separately either flush or depressed from the printing surface. The positioning means comprises (1) means for moving all of the bars to their flush positions, (2) means for blocking the further movement of selected ones of the bars, and (3) means for moving all bars that are not blocked to their depressed position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
An intaglio inking plate comprising a body having a major surface with an aperture therein, a plurality of separately-movable bars in said aperture, each bar having two flat substantially-parallel opposed major sides and a flat end that is movable between a first position flush with said major surface and a second position depressed a small distance below said major surface, and means for positioning each of said bars to said flush position or said depressed position, said positioning means comprising (a) means for moving all of said bars to said flush position, (b) means for blocking the further movement of selected ones of said bars and (c) means for moving all bars that are not blocked to said depressed position.
Claim 2
Dependent Claim
120 words
An intaglio inking plate comprising a body having a major surface with an aperture therein, a plurality of separately-movable bars in said aperture, each bar having two flat substantially-parallel opposed major sides and a flat end that is movable between a first position flush with said major surface and a second position depressed a small distance below said major surface, and means for positioning each of said bars to said flush position or said depressed position, said positioning means comprising (a) means for moving all of said bars to said flush position, (b) means for blocking the further movement of selected ones of said bars and (c) means for moving all bars that are not blocked to said depressed position.
Claim 3
Dependent Claim
35 words
The plate defined in claim 1 wherein each of said bars has a hole therethrough, and all of said bars are stacked on the major sides thereof with the holes therein aligned with one another.
Claim 4
Dependent Claim
40 words
The plate defined in claim 2 wherein each of said holes includes a first boundary portion opposite said flat end, and said means (a) includes means for applying a moving force thereto for moving each bar to said flush position.
Claim 5
Dependent Claim
69 words
The plate defined in claim 3 wherein said means for applying a moving force to said first boundary portion includes a rigid backing member through the holes in said bars, an elastomeric pad between said backing member and all of said first boundary portions of said holes, and means for moving said backing member towards said major surface with force sufficient to move said bars to said flush position.
Claim 6
Dependent Claim
62 words
The plate defined in claim 1 wherein each bar has a tapered end opposite said flat end, and each blocking means includes a slidable locking blade having a tapered surface matching said tapered end and means for selectively moving each locking blade to a blocking position wherein said tapered surface is in contact with said tapered end or to an unblocking position.
Claim 7
Dependent Claim
27 words
The plate defined in claim 5 wherein each locking blade is slidable in a direction that is transverse to the direction of movement of its associated bar.
Claim 8
Dependent Claim
55 words
The plate defined in claim 2 wherein each of said holes includes a second boundary portion remote from said flat end, and said means (c) includes means for applying a moving force to said second boundary portion for moving each unblocked bar to said depressed position while leaving each blocked bar in said flush position.
Claim 9
Dependent Claim
92 words
The plate defined in claim 7 wherein said means for applying a moving force to said second boundary portion includes a rigid backing member through the holes in said bars, an elastomeric pad between said backing member and all of said second boundary portions of said holes, and means for moving said backing member away from said major surface with force sufficient to move said unblocked bars from said flush position to said depressed position, and said pad has sufficient resiliency to permit each blocked bar to remain in said flush position.
Claim 10
Dependent Claim
30 words
The plate defined in claim 8 wherein each second boundary position includes a projection upstanding towards said flat end, and the projections of adjacent bars are offset from one another.
Claim 11
Dependent Claim
42 words
The plate defined in claim 2 wherein all of said bars are stacked on the major sides thereof, and each bar has a groove in one side thereof extending between and spaced from each of said hole and said flat end thereof.
Claim 12
Dependent Claim
31 words
The plate defined in claim 10 wherein all of said bars are stacked on the major sides thereof with no lubricant therebetween, said sides having a flatness tolerance of ±0.0001 inch.
