Definitions

  • This invention relates to perforating apparatus for perforating a tape according to a code, more particularly, but not exclusively for perforating a tape according to a printing telegraph code.
  • Such apparatus is required for printing telegraph purposes and also for perforating a tape required to control computer apparatus.
  • the same code as is used for printing telegraph purposes is frequently used also to control computer apparatus, although other codes may be used for the latter purpose.
  • the tape is perforated with a series of holes arranged in a code combination.
  • the code perforations are used to control the subsequent transmission of a message represented thereby.
  • a power operated typewriter It has previously been proposed for this purpose to cause a power operated typewriter to control a tape perforating mechanism.
  • a power operated typewriter is an expensive piece of apparatus and is not yet in very extensive use. It is the object of the present invention therefore to provide a more economical form of apparatus for attaining this end.
  • perforating apparatus in which key bars, when actuated, positively move type bars to print a character and also control a mechanism for perforating a tape in ac cordance with a code.
  • a tape perforating mechanism for perforating a tape in accordance with a code and means for associating said mechanism with a typewriter having type bars positively linked with the key bars thereof in such manner that actuation of a key bar controls perforation of said tape as well as printing from the type bar linked therewith.
  • a frame carrying perforator key bars means for controlling the perforation of a tape by operation of said key bars, means in said frame to position therein a typewriter and means for causing the actuation of the keys of the typewriter to actuate the said perforator key bars.
  • the perforator key bars may be positioned to be actuated by the typewriter key bars or clear of the latter, so that the typewriter may be used, if required, without perforating a tape.
  • Fig. 1 is an exploded perspective view of a perforator mechanism according to the invention with certain parts broken away or omitted.
  • Fig. 2 shows how a standard commercial typewriter is associated with the perforator key bars.
  • Fig. 3 is a circuit diagram of the electrical connections of the perforator.
  • Fig. 4 is an exploded perspective view of the mechanism for spacing the perforated tape.
  • Fig. 5 is an exploded perspective view of the mechanism for running out tape from the perforator.
  • Fig. 6 is a line diagram of the mechanism for perforating carriage return and line feed codes in the tape.
  • a base plate 1 is provided having means thereon for locating the feet 2, of a standard commercial typewriter 3.
  • each key bar 4 is positioned above a corresponding perforator key bar such as 5.
  • each of the perforator key bars is formed with a flat end portion, such as 9, positioned below the lowest portion of the corresponding typewriter key bar.
  • Each perforator key bar, such as 5, is pivoted on a pivot member 10 which is held between an individual stop 11 and a common rail 12.
  • Each key-bar, such as 5, is held against its pivot member 10 by a spring 13 stretched between the key bar and a bar 14 fixed to the base plate 1 (not shown in Fig. l).
  • the rail 12 is supported on cam discs 15 fixed to a rod 16 journalled in side members 17 of the framework. Exterior to the framework a handle 18 is fixed to rod 16. By means of handle 18 the rod 16 may be rotated to the position shown, in which position cam discs 15 support pivot members 10 so that perforator key bars are in the position shown for key bar 5. In this position, when typewriter key bar 4 is actuated, it strikes the portion 9 of key bar 5 and so causes a code to be perforated in the tape in a manner described hereinafter.
  • handle 18 is rotated through the rail 12 is brought on to the lower portions of cam discs 15 and so key bars, such as 5, are lowered, so that the key bars of the typewriter may be operated without striking the perforator key bars.
  • the perforator key bars are associated with code bars, such as 19, 20, 21, 22 and 23, slidably mounted for vertical movement in horizontal frame members 24.
  • the code bars are formed with projections on which rest pivoted vanes 25, 26, 27, 28, 29.
  • the projections are provided on the code bars in combinations representing a code and each code bar therefore supports a corresponding combination of code vanes.
  • the code vanes rest by gravity on the projections 'of the code bars and in their lowermost positions close contacts 30, 31, 32, 33 and 34 respectively.
  • the lower contact of each pair is mounted on and connected to a common bus bar 35 whilst the upper contacts are connected to individual contact pieces 36 mounted on an insulating support 37.
  • the circuits controlled by the contacts 30 to 34 are shown in Fig. 3. Each set of contacts is connected in series with a coil 38 of an individual electromagnet, one only of these magnets being shown in Fig. 1. These magnets select the punches of the perforator that are required to be operated. When a magnet is operated, the armature 39, Fig. l, pushes to the left in Fig. 1 a corresponding sliding member 48. When the magnet is not operated, as shown in Fig. 1, the corresponding slide member 4%) is held to the right in the figure by its individual spring 41. Punches 42, slidably mounted in a member 43, are held against the upper surfaces of sliding members 40. A sixth member 44, fixed permanently in position, supports a punch 45 for perforating feed holes.
  • each of the code bars 19, 20, 21 and 22 there is a wedge member 46 (Fig. pivotally mounted for a limited amount of rotation. Wedges 46 cooperate with a row of balls 47 held in a channel 48, so that when the balls 47 are displaced by the rise of a code bar, upward movement of any other code bar is prevented.
  • Spring coupled to each code bar is a latch 49 which prevents any reactuation of the corresponding key bar 5, 6, 7 or 8 whilst the code bar is in a raised position.
  • a trip bar 50 Upward movement of a code bar lifts a trip bar 50 fixed to a rod 51 journallcd in the framework of the machine. Also fixed to rod 51 is a locking bar 52 normally held by a spring 53 against a back stop 54.
  • trip bar 50 When trip bar 50 is lifted by a code bar, rod 51 is rotated counter clockwise in the drawing against spring 53 and locking bar 52 is moved below a projection 55 on the lifted code bar and above the projections 55 on code bars that have not been lifted, thus locking the code bars in position.
  • a member 56 Fixed to rod 51 is a member 56 (also shown in Fig. 5) having a horizontal extension 57.
  • Levers 58 and 59 are pulled by individual springs so that projections 68 and 61 thereon rest against extension 57.
  • extension 57 moves upward in the drawing and allows levers 58 and 59 to move to the left in the drawing.
  • Projection 60 of lever 58 moves under extension 57 and holds it against clockwise movement, thus keeping the code bars locked.
  • Projection 61 on lever 59 is cut away, as shown in Fig. 5, so that once the end thereof has passed extension 57, lever 59 moves rapidly.
  • a horizontal extension 62 has been holding a three-armed lever 63 against movement, but when 62 moves to the left, 63 follows under the influence of its spring and allows a bell crank lever 64 to move anti-clockwise and so close contacts 65.
  • Contacts 65 as shown in Fig. 3, close the circuit 0 the energising coil 66 of a perforator magnet and also the circuits of those electromagnets 38 of which the contacts 30-34 have been left closed.
  • the perforator magnet comprises a rectangular laminated core 67 and an energising coil 66.
  • a straight bar armature 68 is drawn upwards into line with the pole pieces of the core 67.
  • the armature 68 is mounted on a pivoted frame 69, a rearward extension 70 of which moves between stops fixed to a U-shaped member 71.
  • Member 71 is fixed to a piston 72 sliding in an oil-filled dash pot 73.
  • the upper end of member 71 is also fixed to a stiff blade spring 74.
  • the blade spring 74 serves to keep the piston 72 in a central position, so that it damps the last small fraction of movement of the frame 69 in either direction.
  • the upward movement of the armature 68 raises the sliding members 40 and the member 44 and so forces punch 45 and any of the punches 42 that rest on raised portions of sliding members 40 through the paper tape 74 to punch a feed hole and a set of code holes in the tape.
  • Upward movement of the armature frame 69 also moves upwand an arm 75 fixed to which is a feed pawl 76, Figs. 1 and 4.
  • the pawl 76 is thus moved to engage another tooth on a feed ratchet 77.
  • a rod 78 fixed to arm 75 disengages a reverse feed pawl 79 from a reverse feed ratchet wheel 80.
  • armature frame 69 Upward movement of armature frame 69 also rotates a lever 81 clockwise in Fig. 1.
  • Lever 81 rotates a lever 82 and the upper end of lever 82 rotates a lever 83 counter clockwise about its pivot 84.
  • This rotation of lever 83 causes a rod 85 fixed thereto to be moved downward.
  • Rod 85 carries pivoted thereon a latch 86, and when the armature 68 has finished its movement, latch 86 has moved far enough to engage a horizontal extension on a lever 87 and rotate this lever counter clockwise. Another horizontal extension of lever 87 rotates levers 58 and 59 counter clockwise and frees arm 57 to allow it to be restored to normal position. As lever 83 rotates, a horizontal arm thereof pushes lever 63 counter clockwise and so rotates bell crank lever 64 to allow contacts 65 to open.
  • lever 88 As rod 85 moves downwards, a bell crank lever 88 follows it and presses against an arm on lever 63. When lever 63 moves counterclockwise, lever 88 moves over an extension thereof and so keeps contacts 65 open until the armature has completed its return stroke, at the conclusion of which, rod 85 rotates lever 88 clear of lever 63,.so that the latter can again snap in behind lever 88 into the position shown in Fig. 1.
  • a latch 89 is provided, spring loaded against member 56 (Figs. 1 and 5).
  • latch 89 also rotates counterclockwise.
  • lever 87 is rotated to disengage levers 58 and 59 from extension 57 of member 56, the upper horizontal extension of lever 87 moves downwards and is engaged by latch 89 which holds it in actuated position until release of the key by the operator allows locking bar 52 to move against its back-stop 54, thus Withdrawing latch 89 from lever 87 and allowing the mechanism to restore to the positions shown in Fig. 1.
  • the figure shift bail 91 is 1305i tionecl a little above the upper ends of code bars, 511.611 as 22 and 23, representing characters in the upper case.
  • Figure shift bail 91 when moved upward, raises a figure shift code bar 96.
  • This code bar rotates an arm 97 fixed'to a rod 98 journalled in the framework of the machine. Rotation of rod 98 causes rotation of a lever 99 which engages another lever 100 and through it rotates latch 86.
  • the latch 86 When the perforator magnet first operates, the latch 86 is therefore unable to act upon the extension of lever 87 as lever 83 rotates.
  • lever 63 is free to rotate clockwise to allow contacts 65 to close a second time.
  • lever 83 As lever 83 is rotated during the first operation of the armature, it moves a member 101 clockwise. This causes a rod 102 to move perpendicular to the plane of the paper, carrying with it a horizontal member 103. This member 103 pushes the figure shift code bar 96 to the right against its spring 104 until a projection there on is free of the face of the figure shift bail 91, whereupon figure shift code bar 96 falls and the projection thereon engages the face of the figure shift hail, the figure shift code bar being thus kept to the right.
  • figure shift code bar 96 when figure shift code bar 96 is lifted the perforator magnet is operated twice in succession. On the first operation the figure shift code combination is perforated. This results from the lifting of code vanes 25, 26, 28 and 29 by the figure shift code bar 96 to open contacts 30, 31, 33 and 34.
  • the figure shift code combination is mark, mark, space, mark, mark and it may be that the code bar corresponding to the key bar actuated has raised code vane 27, and opened contacts 32.
  • a sixth code vane 105 is provided, which is raised by the figure shift code bar 96 to open a sixth set of contacts 106. Contacts 106 are, as shown in Fig.
  • the letter shift code bar 109 acts in the same manner as the figure shift code bar 96 in allowing two successive operations of the perforator magnet. As the letter shift code bar 109 operates all the vanes 25-29, all the contacts 30-34 are opened and an all mark combination is perforated. On the armature stroke, member 103 moves code bar 109 to the right, so that it is pushed clear of the letter shift bail 90 and falls down into the position shown in the drawing. On the second stroke of the magnet the combination representing the selected code bar, such as 21, is perforated.
  • Typewriter shift key Some of the keys on the typewriter represent two different characters, both being in the upper case in the teleprinter code. The distinction between them in the typewriter is made by means of a shift key. Accordingly in the perforator, two code bars, such as 22 and 23, are provided for each such typewriter key and a key bar 111 is positioned to be actuated by the typewriter shift key. With the typewriter shift key in unoperated position, operation of perforator key bar 5 acts to raise code bar 22 through a member 112 and not directly. When key bar 111 is operated, a bar 113 is lifted and a member 114 is spring urged to follow it. Member 114 is fixed to a rod 115 journalled in the framework of the machine, and rod 115 therefore rotates clockwise. A member 116 is fixed to rod 115 and so pulls member 112 out of position to engage code bar 22 and into position to engage code bar 23. Accordingly, when key bar 5 is now actuated, code bar 23 is raised and not code bar 22.
  • a separate key 117 For the purpose of allowing the perforated tape 74 to be spaced backwards, a separate key 117, Fig. 4 is provided, independent of the keys of the typewriter.
  • a cam member 118 When the perforator back-space key 117 is operated a cam member 118 is rotated anti-clockwise and acts on a rod 119 to cam it in clockwise direction.
  • Rod 119 is fixed to an arm 120 which is also fixed to a shaft 121 journalled in the frame of the machine.
  • Fixed to shaft 121 is a member 122, so that when shaft 121 rotates in a clockwise direction, member 122 rotates in the same direction and removes feed pawl 76 from engagement with the feed ratchet 77.
  • cam member 118 rests on a rod 123 fixed to an arm 124 carrying the backward feed pawl 79, so that counter-clockwise rotation of cam member 118 and arm 124 rotates pawl 79 whilst it is in engagement with back-space ratchet 80 and so steps the paper tape 74 one step backwards.
  • an erase key bar 7, Fig. l is provided independent of a key bar in the typewriter. Actuation of key bar 7 lifts up an erase code bar 20. This code bar lifts all five vanes 25-29. As the erase code is the same as the letter shift code for printing telegraph purposes, the erase code bar 20 in rising also lifts the letter shift bail 90 if this is in its lower position. In such case the letter shift code bar 109 is also lifted by the rise of the letter shift bail 90. The normal action of the lifting of the letter shift code bar 109 in causing two strokes of the armature of the perforator magnet is, however, prevented in this case.
  • ey ar 8 is a tuat d y the typ e space key and raises a code bar 19 which raises code vane 27 only to open contacts 32, The code bar 19 thus causes perforation in the tape of the code space, space, mark, space, space.
  • the code bar 19 does not, however, act on either the letter shift bail 90 or the figure shift bail 91.
  • the key bar 8 is positioned somewhat closer to the space key bar of the typewriter than are other perforator key bars, to the corresponding typewriter key bars so that a greater proportion of the movement of the typewriter space key bar is used in operating the perforator than in the case of other typewriter key bars.
  • Run out perforator key A key external to the typewriter is provided for run ning a quantity of blank tape out of the perforator. This key actuates a key bar 128, Fig. 5. Key bar 128 raises a bar 129 similar to the code bars but differing therefrom in several respects. Bar 129 does not act on any of the code vanes. It cooperates with the trip bar 50 but is not provided with any projection 55 to co-act with the looking bar 52 (Fig. 1).
  • Bar 129 operates on trip bar 50 to rotate member 56 and so. allow levers 58 and 59 to move to the left as previously described to allow contacts 65 to close and operate the perforator magnet 66, Fig. 1. As all the magnets 38 are operated, all sliding members 40 are moved to the left and the punches 42 rest on the lower portions of members 40. Consequently the only punch operative is punch 45 to punch a feed hole in the tape 74.
  • lever 83 On the armature stroke, lever 83 is rotated, as previously described, and moves rod 85 and latch member 86 downward.
  • Bar 129 acts in the same manner as the letter shift code bar 109 or the figure shift code bar 96 to operate lever 99 and through lever 100 to rotate latch 86, so that when rod 85 moves downwards, carrying with it latch 86, the latter is clear of the horizontal extension of lever 87, so that levers 58 and 59 are not moved.
  • lever 63 is free to rotate clockwise and allow contacts 65 to close a second time, as previously described for the double operation of the perforator magnet when a case shift signal is inserted.
