US3719262A — Method of and machine for storing data

Claim 1

Independent Claim 80 words

The method of storing data on a surface comprising the steps of superimposing one on the other of a visible man readable conventional type character and instrumentality substantially invisible but machine readable code symbol, the superimposing steps being accomplished by immediately successive strokes of a single insturmentality carrying said character and symbol against different areas of an interposed ribbon, the position of said instrumentality and said surface being shifted between strokes sufficiently to achieve said superimposing of character and symbol.

Claim 2

Independent Claim 80 words

The method of storing data on a surface comprising the steps of superimposing one on the other of a visible man readable conventional type character and instrumentality substantially invisible but machine readable code symbol, the superimposing steps being accomplished by immediately successive strokes of a single insturmentality carrying said character and symbol against different areas of an interposed ribbon, the position of said instrumentality and said surface being shifted between strokes sufficiently to achieve said superimposing of character and symbol.

Claim 3

Independent Claim 80 words

The method of storing data on a surface comprising the steps of superimposing one on the other of a visible man readable conventional type character and instrumentality substantially invisible but machine readable code symbol, the superimposing steps being accomplished by immediately successive strokes of a single insturmentality carrying said character and symbol against different areas of an interposed ribbon, the position of said instrumentality and said surface being shifted between strokes sufficiently to achieve said superimposing of character and symbol.

Claim 4

Independent Claim 80 words

The method of storing data on a surface comprising the steps of superimposing one on the other of a visible man readable conventional type character and instrumentality substantially invisible but machine readable code symbol, the superimposing steps being accomplished by immediately successive strokes of a single insturmentality carrying said character and symbol against different areas of an interposed ribbon, the position of said instrumentality and said surface being shifted between strokes sufficiently to achieve said superimposing of character and symbol.

Claim 5

Dependent Claim 29 words

The method as set forth in claim 1 in which the code symbol is first placed on the surface and the readable character is then placed over said symbol.

Claim 6

Dependent Claim 29 words

The method as set forth in claim 1 in which the readable character is first placed on said surface and the code symbol is then placed over said character.

Claim 7

Dependent Claim 227 words

A typewriter including a platen, a constantly rotating power shaft, a plurality of cams on said shaft, at least one clutch on said shaft for simultaneously starting rotation of said cams and stopping said cams after 360* of rotation, a plurality of type arms and related type slugs thereon pivotally mounted on a shiftable segment, manually operable keys for causing actuation of said clutch and cams and any selected type arm, a type arm actuating bail, a first cam of said plurality of cams shaped to cause duplicated movement of a follower connected to said bail during 360* rotation of said first cam whereby said bail will be oscillated twice and said selected type arm will be caused to strike said platen twice in the period of said 360* rotation, a second cam on said power shaft controlled by a clutch simultaneously with said first cam, said second cam arranged to shift said segment between strikes of said type arm whereby on said second strike a different part of said type slug will engage said platen and whereby after said second strike said second cam will return said segment to its original position, and a third cam on said power shaft controlled by a clutch simultaneously with said first and second cams arranged to actuate an escapement after said second strike to advance said platen one space.

Claim 8

Dependent Claim 227 words

A typewriter including a platen, a constantly rotating power shaft, a plurality of cams on said shaft, at least one clutch on said shaft for simultaneously starting rotation of said cams and stopping said cams after 360* of rotation, a plurality of type arms and related type slugs thereon pivotally mounted on a shiftable segment, manually operable keys for causing actuation of said clutch and cams and any selected type arm, a type arm actuating bail, a first cam of said plurality of cams shaped to cause duplicated movement of a follower connected to said bail during 360* rotation of said first cam whereby said bail will be oscillated twice and said selected type arm will be caused to strike said platen twice in the period of said 360* rotation, a second cam on said power shaft controlled by a clutch simultaneously with said first cam, said second cam arranged to shift said segment between strikes of said type arm whereby on said second strike a different part of said type slug will engage said platen and whereby after said second strike said second cam will return said segment to its original position, and a third cam on said power shaft controlled by a clutch simultaneously with said first and second cams arranged to actuate an escapement after said second strike to advance said platen one space.

Claim 9

Dependent Claim 131 words

In an electric typewriter which includes a platen and an escapement mechanism, means for causing a selected type arm having a type slug with at least two characters thereon one above the other to strike the platen twice before operation of the escapement, means for shifting the type arm crosswise of said platen between strikes whereby the position of engagement of one character with said platen on the fIrst strike will be the position of engagement of the other character with said platen on the second strike said means for causing the double strike of said type arm comprising a spring driven type action bail, a two lobe cam, and a cam follower connected to said bail to cause two oscillations of said bail for each 360* rotation of said cam.

Claim 10

Dependent Claim 131 words

In an electric typewriter which includes a platen and an escapement mechanism, means for causing a selected type arm having a type slug with at least two characters thereon one above the other to strike the platen twice before operation of the escapement, means for shifting the type arm crosswise of said platen between strikes whereby the position of engagement of one character with said platen on the fIrst strike will be the position of engagement of the other character with said platen on the second strike said means for causing the double strike of said type arm comprising a spring driven type action bail, a two lobe cam, and a cam follower connected to said bail to cause two oscillations of said bail for each 360* rotation of said cam.
