Justifying typewriter with conjointly oppositely movable type head and platen

Claim 2

A typewriter with a platen having an axis for carrying a type receiving sheet; means mounting said platen for movement parallel to its axis; a character impression type matrix; means for moving said type matrix in a path paralleling the axis of said platen; means for selecting a matrix type character position and striking said type matrix against said type receiving sheet for printing a type character; distributor means for sensing the number of space units used responsive to a first typing of a line of type characters and registering the space units remaining after said first typing with respect to a desired line length; and means responsive under the control of said distributor means for moving said platen, during a second typing of said line of type characters, in aliquot portions of said remaining space units in a direction opposite the direction of matrix movement during said first typing of said line of type characters until said remaining space units are equally distributed throughout the line in spaces among said line of type characters.

Claim 3

A typewriter with a platen having an axis for carrying a type receiving sheet; means mouNting said platen for movement parallel to its axis; a character impression type matrix; means for moving said type matrix in a path paralleling the axis of said platen; means for selecting a matrix type character position and striking said matrix against said type receiving sheet for printing a type character; justifying means including means for counting the number of word spaces between words typed during the typing of a non-justified line and for sensing the space remaining at the end of the non-justified line with respect to a desired line length, said justifying means including means for apportioning said space remaining as incremental increases in spacing between the words during a second typing of the same line; and means controlled by said justifying means for moving said platen, during said second typing, by said incremental increases in a direction opposite the direction of movement of said matrix during typing of said non-justified line, whereby said incremental increases are apportioned between said words during said second typing.

Claim 4

A typewriter with a platen having an axis for carrying a type receiving sheet; means mouNting said platen for movement parallel to its axis; a character impression type matrix; means for moving said type matrix in a path paralleling the axis of said platen; means for selecting a matrix type character position and striking said matrix against said type receiving sheet for printing a type character; justifying means including means for counting the number of word spaces between words typed during the typing of a non-justified line and for sensing the space remaining at the end of the non-justified line with respect to a desired line length, said justifying means including means for apportioning said space remaining as incremental increases in spacing between the words during a second typing of the same line; and means controlled by said justifying means for moving said platen, during said second typing, by said incremental increases in a direction opposite the direction of movement of said matrix during typing of said non-justified line, whereby said incremental increases are apportioned between said words during said second typing.

Claim 5

A typewriter comprising: an elongated platen for carrying a type receiving sheet; matrix typing means for typing characters on said sheet; means for mounting said matrix typing means for movement along said platen in a typing path; keyboard means for controlling movement of said matrix typing means including means for selectively actuating said matrix typing means to strike a matrix type character against said sheet and moving said matrix typing means in a typing direction by one increment along said typing path and word spacer means for moving said matrix typing means in said typing direction by one increment along said typing path to define a word type space; means for mounting said platen so as to be stationary while said matrix typing means is incrementally moved along said typing path for typing characters on said sheet and including means for moving said platen axially in a direction opposite to said typing direction when a force in said opposite direction is imparted to said platen; justifying means including means for counting the number of said word type spaces occurring during typing of an unjustified line of type along said typing path and for determining the remaining line space from the end of said typing path relative to a desired length and for apportioning the remaining line space among said word type spaces in a subsequent typing of the same line of type to obtain a justified line of type; and means controlled by said justifying means for imparting force to said platen for moving said platen in said opposite direction by an amount apportioned by said justifying means when said word spacer means is actuated during a subsequent typing of the same line of type so as to obtain said justified line of type.

Claim 6

A typewriter comprising: an elongated platen for carrying a type receiving sheet; matrix typing means for typing characters on said sheet; means for mounting said matrix typing means for movement along said platen in a typing path; keyboard means for controlling movement of said matrix typing means including means for selectively actuating said matrix typing means to strike a matrix type character against said sheet and moving said matrix typing means in a typing direction by one increment along said typing path and word spacer means for moving said matrix typing means in said typing direction by one increment along said typing path to define a word type space; means for mounting said platen so as to be stationary while said matrix typing means is incrementally moved along said typing path for typing characters on said sheet and including means for moving said platen axially in a direction opposite to said typing direction when a force in said opposite direction is imparted to said platen; justifying means including means for counting the number of said word type spaces occurring during typing of an unjustified line of type along said typing path and for determining the remaining line space from the end of said typing path relative to a desired length and for apportioning the remaining line space among said word type spaces in a subsequent typing of the same line of type to obtain a justified line of type; and means controlled by said justifying means for imparting force to said platen for moving said platen in said opposite direction by an amount apportioned by said justifying means when said word spacer means is actuated during a subsequent typing of the same line of type so as to obtain said justified line of type.
