Abstract: 16,214. Lean, C., [Schnellsetzmaschinen- Ges.]. July 12. Setting type ; assembling matrices; justifying type and matrices ; driving-mechanism.-In type and matrix setting machines operated by register bands, the band is caused to bring into action a device which enables a space to be set after each character, in the production of spaced matter, and an additional space to be set between the words for justification purposes, in those cases in which a line cannot be set full enough. In producing spaced matter, the composer perforates a symbol on the band before beginning the spaced matter. A. perforation is similarly made for justification post-spacing either before or after the perforations which represent the line to be supplemeated. Fig. 1 shows an arrangement, adapted for postspacing, applied to a matrix-setting and line-casting machine. An electro-magnet 2 for setting the normal space-bars for the word-spaces is connected, as shown, with electro-magnets 3, 5 so that when the electro-magnet 3 is energized by the action of the special post-spacing perforation in the register band, circuit made in the usual manner through the electro-magnet 2 is closed through the pillar 7 and armature 6, and the electro-magnet 5 is energized. This causes the attraction of the armature 11 and allows a bell-crank lever 16, 17 to rock under the action of its spring 21 and bring a spring 18 into contact with a screw 20, which is connected through an electro-magnet 14 with an electro-magnet 4 operating the releasing-device of the magazine channel which contains the additional space bars for enlarging the word-spaces. When the current through the electro-magnets 2, 5 is interrupted, the armature 11 is released, and by contact with the arm 16 completes a circuit through the electro-magnet 4. The electro-magnet 14 is simultaneously energized to break the circuit and bring the lever 16, 17 to normal position. The setting of a normal space-bar by the electromagnet 2 is only accompanied by that of an additional space-bar when the electro-magnet 3 is energized. The armature 6 is held down upon the pillar 7 by means of a roller 8, but is returned to normal position, after a line has been set up, mechanically or by an electro-magnet 24. Additional devices may be included in the circuit of the electro-magnets 4, 14 for delaying the motion of the register band during the setting of the additional space-bar. Fig. 2 shows an arrangement for producing spaced matter. The character elements are set in known manner by the action of electro-magnets 29 under the control of switches 30, 31 which are connected to main conductors 32, 35. Conductors 33, 34 lend to space-bar setting-mechanism as described above in connexion with Fig. 1. When spaced matter is not being produced, the armature 6<a> lies against the insulated pillar 7<a> and the connexion between the conductors 32, 35 by way of the conductors 33, 34 is short-circuited. The special perforation for spaced matter causes the electro-magnet 3<a> to be energized, and the armature 6<a> is moved to bring the space-bar setting-mechanism into circuit with the conductors 32, 35 so that after each excitation of an electro-magnet 29 for setting a character, a space-bar is set. The armature 6<a> is held in the working position until it is restored to contact with the pillar 7<a> by means of an electro-magnet 24<a> controlled by a perforation in the band.
