摘要

A system to photographically execute typographical compositions, with its own keyboard and applicable to any typewriter, in which fundamentally the same writer writing on the keyboard of the typewriter forms a positive or negative photographic capable of being used directly in the room. Machines of the publishing house, with the possibility of amending his writing, by inercambio of lines, meeting for these purposes in such system, jointly and in combination, the following conditions: A) a special keyboard operable directly by the editor himself, or remotely from the keyboard of a conventional typewriter by means of appropriate electrical connections; B) an electromechanical organization, linked to the special keyboard (a) of the system, based on displaceable conical bars perpendicular to a graduated rule, which controls and limits the progress of the writing that is executed, which interposing automatically in the free spaces between words and signs are able to increase these spaces to justify each line; C) a rotating drum that acts as a mechanical memory, composed of a certain number of discs, each of them provided with diametrically displaceable stops, depending on the pulsations made on the keyboard (a) and in accordance with the pulsed signs and letters ; D) a transparent drum rotating on its axis, on the surface of which are printed, in several parallel circles and at heights, all the signs of a certain style and size and which makes angular turns according to the situation of the stops selected in the drum (c) or mechanical memory; E) a photographic object, with its corresponding obturator, located in front of the transparent cylinder (c) and with its optical axis coinciding with the radial extension of a diameter of the cylinder; F) a camera, movable with respect to the axis of the transparent cylinder, in magnitudes proportional to the justification achieved in the keyboard (a) for each typed line; G) an automatic drill for laterally perforating the film at the beginning and end of each photographed line; H) the precise electromechanical organization to synchronize the previous organs, conditioned by the general and special control keys corresponding to the end of the line, to change the font style, release the mechanical memory, disable a line already recorded in this memory mechanical, and for the use connection of it.
