  • the print wires 35 are preferably attached to reduced end portions 36 of the armatures 25 by being wrapped tightly therearound. It should be noted, however, that the Wires 35 may be attached by any other suitable means.
  • the print wires 35 extend from the armatures 25 to the carriage mechanism 12 'wherein they are positioned to print a character.
  • a platen 40 is provided for supporting a paper web 41 in a printing position. Between the web 41 and the carriage 12 there is positioned an inking ribbon 42 which serves to provide ink for printing on the paper web 41 and which may be supported in any suitable manner.
  • the armatures 25 are normally pulled into engagement with the pole faces of the electromagnets 26 by means of the coils of the magnets being energized. When it is desired to print a character, selected ones of the coils of the magnets 26 are deenergized there by allowing their respective armatures 25 to move to the left (FIG.
  • the carriage member 12 is comprised of a frame member 45 upon which is mounted a guide block member 46.
  • the guide block member 46 serves as the final guide for the print wires 35 and also serves to confine the wires 35 in a proper matrix relationship so that the selective deenergization of predetermined ones of the magnets 26 will cause a character of a predetermined configuration to be printed.
  • a support member 47 At the right end of the carriage 45 (FIG. 1) there is provided a support member 47 to which is attached the cable guide 11.
  • a support mechanism for the frame consisting of a pair of rollers 48 which are attached to the frame 45 and which are mounted in engagement with a portion 49 of the frame of the printer so as to allow the carriage 12 to be moved axially along the platen 40 to eifect character spacing for the copy which is printed on the web 41.
  • a cable gripping structure 50 which grips a cable 51. The cable 51 is moved by any suitable spacing means so as to advance the carriage mechanism 12 along the frame portion 49 to effect character spacing.
  • the cable guide 11 is comprised of a plurality of guide disks 60.
  • Each of the guide disks 60 has formed through it a plurality of apertures 61, each for receiving and guiding an individual one of the print wires 35.
  • lugs 62 each of which is comprised of a pair of radially extending arms 63 and a slot 64 formed therebetween in the guide disk 60.
  • the function of the lugs 62 is to support the guide disks on a plurality of guide wires 65 which are attached at one of their ends to the support member 47 and which are attached near their other end to a cable guide supporting bracket 66 which is attached to the armature support ring 17 of the magnet housing structure 10 by means of threaded fasteners 67.
  • the guide wires 65 are of considerably larger diameter than the print wires 35 and are used to support the guide disks 60 and the print wires 35 while being flexible enough to permit movement of the carriage 12 with respect to the platen 40, the frame portions 49 and 15 and the magnet housing structure 10.
  • the guide disks 60 are spaced uniformly along the length of the guide wires 65 at intervals suitable to provide adequate support and guidance for the print wires 35.
  • the guide disks 60 are maintained in their respective positions by locating springs 70, one of which is mounted on each of the guide wires 65.
  • the locating springs 70 secure the guide disks 60 with respect to each other and with respect to the frame portion 15 of the printer by gripping the lugs 62 of the guide disks 60 between adjacent ones of the coils of the springs.
  • the locating springs 70 extend substantially the entire length of the guide wires 65.
  • the locating springs 70 need not be comprised of a single spring but may be a plurality of springs located adjacent each other along the length of the guide Wires 65.
  • the thickness of the guide disks 60 when measured axially along the guide wires 65 should be approximately equal to the diameter of the print wires 35. Such a thickness provides adequate support and guidance in the print wires 35 while assuring that no matter how the support cable 11 is flexed or twisted the print wires 35 cannot possibly become bound against the side walls of the guide apertures 61.
  • the guide disks 60 are separated into three distinct groups.
  • the first of these is comprised of the guide disks 60 mounted on the guide wires 65 between the armatures and the frame 15 of the printer.
  • the guide disks 60 in this group are of increasingly larger diameter and the guide apertures 61 of the guide disks 60 of this group are located with respect to each other at increasing distances so as to fan the guide wires out to positions where they may be attached to the armatures 25.
  • the guide disks 60 in the group of guide disks nearest the support 47 are of increasingly smaller diameter and the distances between the guide apertures 61 of adjacent guide disks 60 of this group are decreased so as to compact the print wires 35 so that they may be guided through the guide block 46 suitably to form a proper printing matrix.
  • a group of guide disks 60 which comprise the majority of the guide disks 60 in the cable guide 11 in which the guide disks are of equal size and in which the distance between the guiding apertures 61 is constant.
  • this group of guide disks the path of travel of the print wires 35 is substantially parallel. It should be realized, however, that the number of disks in one of the groups is not necessarily equal to the number shown in the drawing but is to be varied in order to fan out and to constrict the print wires 35 suitably in accordance with the dot matrix printer used in an individual case.
  • a cable for a dot matrix printer comprising:
  • each disk having a guide aperture individual to each print wire for receiving and guiding the print wires;
