Claim 1
Independent Claim
211 words
A display and control device for the setting, justification and checking of lines in a photosetting composition machine having a carriage, said device comprising: a guide rail adapted to be mounted on said carriage and having front and rear sIdes provided with respective longitudinally extending guide channels; a slider slidably received in the guide channel of said front side for indicating the start of a line, said slider being formed with a further longitudinally extending guide channel; a tongue slidably received in said further guide channel for indicating the end of a line; a rack slidably mounted in the guide channel of said rear side of said guide rail and connected with said tongue; tabulator means connected to an underside of said guide rail and extending therealong; a line length indicator movable along the front side of said guide rail and extending beneath said tabulator means; photoelectric means carried by said line length indicator and cooperating with said tabulator means for producing a control signal for the device; and a justification indicator extending along the upper side of said guide rail and shiftable therealong, said front side of said guide rail being provided with scales cooperating with said indicators for displaying the line end location and the justification of the line.
Claim 2
Dependent Claim
211 words
A display and control device for the setting, justification and checking of lines in a photosetting composition machine having a carriage, said device comprising: a guide rail adapted to be mounted on said carriage and having front and rear sIdes provided with respective longitudinally extending guide channels; a slider slidably received in the guide channel of said front side for indicating the start of a line, said slider being formed with a further longitudinally extending guide channel; a tongue slidably received in said further guide channel for indicating the end of a line; a rack slidably mounted in the guide channel of said rear side of said guide rail and connected with said tongue; tabulator means connected to an underside of said guide rail and extending therealong; a line length indicator movable along the front side of said guide rail and extending beneath said tabulator means; photoelectric means carried by said line length indicator and cooperating with said tabulator means for producing a control signal for the device; and a justification indicator extending along the upper side of said guide rail and shiftable therealong, said front side of said guide rail being provided with scales cooperating with said indicators for displaying the line end location and the justification of the line.
Claim 3
Dependent Claim
77 words
A display and control device as defined in claim 1, further comprising an axially shiftable rotatable knob; first gear means connecting said knob with said rack and second gear means connecting said knob with said slider; indexing means for rotating said knob and indexing said tongue in full units of length in one axial position of the knob; and means enabling joint movement of said tongue and said slider in a second axial position of said knob.
Claim 4
Dependent Claim
78 words
The display and control device defined in claim 2 wherein said photoelectric means includes a light source producing a light beam and photosensitive means spaced from said light beam, said tabulator means including a multiplicity of tab stops displaceable from a normal position into a set position interrupting said light beam, and means for setting said tab stops, said device further comprising a line end tongue interrupting said beam in a predetermined position of said line length indicator.
Claim 5
Dependent Claim
21 words
