Definitions

  • the invention relates to a mechanism for producing linear displacement by various steps of predetermined lengths, especially for use in connection with photographical type set-ting machines.
  • the object of the invention is to provide a simple mechanism which, notwithstanding, will give better results than other mechanisms of the same type as regards exactness, reliability and rapidity of operation.
  • Another object of the invention is to reduce the very numerous grades of stepforward displacement required for practical purposes into a few predetermined lengths.
  • a further object of the invention is to satisfy all requirements and possibilities of photographic reproduction when the invention is used in connection with a photographical type setting machine.
  • FIG. 1 is a sectional elevation of the mechanism
  • Fig. 2 is a plan view of the same, partly in section, in the position of rest.
  • Fig. 3 is a detail view of the type patterns of a photographical type setting machine used in connection with the invention
  • Fig. 4 is a detail elevation of the parts appearing in section in Fig. 2.
  • slide 3 takes up in a direct manner, in the form of its strokes of varying length (such variation depending on the limits set), the selected linear displacements e. g. type widths, either in their actual dimensions or on a certain scale. It only remains to transfer such displacements, by means of a coaster or free-run mechanism to a conveyer which acts on' the tool or device to be displaced, for instance, the carrier of the light-sensitive set ting plate, in order to ensure photographical type setting to be effected in the proper manner required for printing;
  • the step length selectors are subordinated to a keyboard, per se known, for instance to a typewriter keyboard, various keys of which may be correlated with each step length selec tor, for instance, the switch of a magnet 9, the mechanism being thus operated in the manner of writing by means of a typewriter.
  • the predetermined number of stroke lengths of the controller slide 3 may thus be connected with any desired plurality of keys.
  • different selectors may also be subordinated to a common key, the current circuits of such selectors being branched-ofl so as to pass through two or more change-switches, which are operated by means of a change key similar to that of a typewriting machine.
  • the actual magnitude of the type-widths depends on the grade of type to be set, e. g". on the ratio of photographic enlargement selected.
  • the proportion of the different types, determined by the corresponding stroke lengths of slide 3 remains. in general unaltered and accordingly it will be possible according to the invention to derive the varying lengths of step required in each case from the basic lengths available, the number of which may, as in the example shown, be eight, such derivation being efiected by means of a transmission adjustable for different transmission ratios, such transmission being inserted between the controller slide 3 and the element to be displaced e. g.
  • the transverse slide 15 has an electromagnet 29 mounted thereon, by means of which a soft-iron travelling conveyer 28 is coupled to slide 15 during each stroke of the latter, when the magnet 29 is energized.
  • a reversed connection arrangement is provided between magnet 29 and the fixed magnet 30, only one of the magnets being energized at a time.
  • Conveyer bar 28 will therefore be released by magnet 30 and gripped by magnet 29 when the forward step, is made whilst during the reverse stroke of slide 15 the opposite process takes place, the bar 28 being now released by magnet 29 and gripped by magnet 30'.
  • bar 28 will move forward step by step and will be fixed in each position.
  • hand-wheel 26 is first adjusted so as to correspond to the wanted ratio of type reproduction, then the tional cases it will be necessary to provide, in
  • the uniformly distributed type patterns of photographical type setting machines when used in connection with the arrangement described are so arranged as to make the left-hand border of each type image get always on the same place, notably make it coincide with the left-hand border of the line along which it is intended to travel.
  • Fig. 3 this is shown, to make it quite plain, on three type images placed one above the other, the three type paterns having the same aXis of division 83 in come mon i. e. possessing division fields 34 of equal size.
  • the left-hand, i. e. initial borders are displaced from the centreline of division 33 in the same initial sense and to the same distance 35 from the aXis 33.
  • the starting type of the line is photographically exposedwhilst the light-sensitive plate or film or like is still in that position of rest, starting from which this plate etc. begins to travel along the line in question, and that all individual exposures, and, therefore, those of the other types of the lines as well, precede the corresponding step-forward dis placement oil the light-sensitive sheet. If we proceed in this manner, the left-hand borders of all lines of a column will be in alignment, spaces between words will always be exact and the difierences which might arise from the differences of initial types will be eliminated automatically.
