A copy holder, base is shown at 19 and extending upwardlyqfirom this base is a, rod 20. Mountedupon this rod in any. convenient manner is a copy holder plate 21. The base 19, rod-20 and plate 21, together constitute a copy holder which may be of the usual or any desired construction. A typewriter frame is shown at 22, the platen roller at 23, the carriage at 24, and the keys at 25. The inking ribbon appears at 26 and the ribbon casings at 27 and 28, the ribbon guide appearing at 29. The platen wheelis shown at 30 and is used for turning the platen roller. The line spacing scale is shown at 31, and the adjusting lever for controlling spacing of the lines appears at 32, these parts being of the usual construction or any other construction preferred. The spacing lever of the typewriter appears at 33 and is shifted to the right according to Fig. 1, in a manner well known in this art, for the purpose of turning the platen roller 23 step by step and otherwise executing the line spacing. This lever is provided with athumb piece 34 of the form shown more particularly in Fig. 2, and is journaled upon a pivot pin 35, the latter being carried by the typewriter carriage 24.
An arm 36 having a general arcuate form is provided at one of its ends with a. wing 37 and this wing is secured to the spacing lever 33 by a bolt 38 and nut 39, the bolt 38 being curved at its inner end for the purpose of partially encircling the adjacent body portion of the spacing lever. The arm 36 is thus readily secured to the spacing lever and may be easily disconnected therefrom. The arm 36 is provided with notches 40, serving, to some extent, the purpose of graduations. Slidably mounted upon the arm 36 is a sleeve 41 having the form indicated more particularly in Figs. 2 and 4. A spring wire 42 is mounted at one of its ends upon the sleeve 41 and bent as indicated in Fig. 4. This spring wire is provided at its upper end with an eye 43 and with a portion extending through some one of the notches 40, according to the position in which the sleeve is placed relatively to the arm 36, as may be understood from Fig. 2.
The casing 41' is provided with a pair of notches 44 adapted to be brought into registry with any one of the notches 40, so that the wire 42 may, by extending through the notches 44 and some one of the notches 40,
hold the sleeve 41 temporarily in a predetermined position .relatively to the arm 36. The operator by shifting the sleeve 41 along the arm 36 and securing the sleeve in differ cut-positions by aid of the notch 40, as just described, can control, within reasonable limits, the distance through which the sleeve 41 travels with each movement of the spacing lever 33. The sleeve 41 is provided with a tongue 45 of sheet metal and pivotally connected with this tongue is a tubular sleeve 46, which is threaded internally. A tubular stem 47 is provided with a thread 48, which fits into the sleeve 46. The tubular stem 47 is also fitted with a sleeve 49 secured thereupon by aid of a thread 50. A metallic wire 51 extends through the sleeve 49 and into the tubular stem 47, being secured firmlywithin this stem preferably by solder- 111g.
Mounted rigidly upon the typewriter carriage 24 is a bracket 52, this bracket being detachably held in position by means of a screw 53. A tubular sheath 54 having the general form of a hollow cable is secured to the bracket 52 by aid of a sleeve 55 with which this bracket is provided for the pur pose A screw 56 extends through the wall. of the sleeve'55 and grips the adjacent end of the tubular sheath. The wire 51 is both smooth and flexible and works easily in the general direction of its length within the tubular sheath.
Mounted rigidly but detachably upon the carriage 24 of the typewriteris a bracket 57 which is provided with a rearwardly extend ing tongue 58. Extending through a hole in this tongue is a threaded bolt 59 and fitted upon this threaded bolt is a revoluble nut 60. A fastening 61 having the form of a metallic ball is secured upon the bolt 59 by a pin 61, as will be understood from Fig. 6. The ball 61 is providedwith-an opening and a chain 62 is secured to the ball by extending into this opening and being held therein preferably by the use of solder, as may be understood from Fig. 6. The chain 62 engages a pulley 63, the latter being journaled upon a bolt64. This'bolt is carried by a bracket 65 which is mounted upon the frame workof the typewriter by aid of a boltr66. The bracket 65 isalso provided with a sleeve 67. A tubular sheath 68 similar to the sheath 64 extends into the sleeve 67 and is secured therein by aid of a screw 69. The chain 62 extends entirely through the sheath 68 and is controllable by movements of the carriage, so that as the carriage 'moves step by step to the left thechain is fed through the sheath 68, being drawn out of the opposite end thereof, as hereinafter described.
I will next describe the indicator mechanism, and parts associated therewith, as shown in Figs. 10 to 18 inclusive. A face plate 69 is bent substantially in U-form, as may be seen from Fig. 7, and thus provided at its top and bottom with wings 70 and 71 integral with it. These wings are provided with slots 72, and extending through these slots is a pivot pin 73. This pin is provided at one of its ends with a milled head 74 and fitted upon it at its opposite end is a milled nut 75. A hinged plate is shown at 76, and is provided with a laterally extending portion 77 of considerable length, the edges of this laterally extending portion being bent toward each other so as to form a channel 78, as will be understood from Fig. 7. The hinge plate 76 is further provided with strengthening ribs 79 formed init by crimping. The 130 hinge plate '7 6 is provided at its top and bottom with leaves 79 integral with it these leaves being-provided With holes through which the pivot pin 73 extends. By loosening themut 75 the pivot "pin 73 maybe movedslightly along the slots 72 and the nut 7 5 being tightened, the pivotpin is thus located in a 'new positio11. "The pivotal pointof the extending portion77 is thus rendered adjustable.
The tubular sheath 68 ehtends into a bearing 80 Where it is rigidly held in position by-a screw 81,. The cable 62fafter emerging from the sheath 68 and bearing 80' extends to the right according to Fig. 7 and into a casing 82Which for this purpose is provided" With jaw hole 83. 'Revolubly mounted Within the casing 82 is admin 84 upon which the chain 62 is partially wound as indicated in Fig. 17= Aspiralspring85 is secured at its outer end to this drumfand at its inner end to a shaft 86 the latter being' se'cured rigidly upon the outer end of the arm 77. The spring 85isfalso under tension, and by its tende'ncy to turn the drum 84, maintains the chain 62 likewise always undertension. A s'lidingplate 87 provided With a pointer 88 is mounted upon the arm 77 asindicated, and is'ada'ptecl to slide thereupon in the general direction of the length of the arm. This slidingpla te is bent" into the form indicated in Fig. 16 and is provided 'With portions89 having the form of tongues andalso with an edge 90, the tongues89and' edge90 being so bent as to fit into the channel 7 8, as may be understood from Figs'15 and 16. The sliding plate 87 is further provided ith a' hole91. Extending through this hole is a threaded bolt 92, which is provided With a head 93. Encircling this bolt is a spiral spring 94. A nut is fitted upon the threaded bolt 92 and engages the spring 94. The chain 62 extends through a hole 96 infthe threaded bolt 92. Thetension of the spring 94 by forcing the bolt 92 to the right according to Fig. 15 causes the button 93 to pre'ss the chain 62 against the adj acent portion of the sliding plate 87. This holds the sliding plate firmlyupon the chain and causes itflto partake of the longitudinahmotion of-the latter. i P
The operator by pressing upon the' bolt 92 or upon the nut '96 can, by moving the button 93 'to the left according to Fig. 15, relax the pressure normally exerted by the button 93 upon thechain and canthus unloosen the sliding plate87 relativelyto the chain. By doing this the operator canshift the position of the sliding plate 87 relatiyely'to the chain-62, and by sogdoing can shift the limitsof travel of the pointer 88 relatively to 1 the" copy holder 'plate "21. Mounted rigidly upon' theba'ckof the copy holder plate 21 is a rack bar 94 provide'd with teeth 95 extending parallel: "with the general plane off the copy holder board '21 and spaced" slightly therefromfas may be understood from Fig. 12. Two casing plates 96 and 97 are fitted together so as to Q form a casing, asi'vill be understood from Figs. 8, 9and 10. y The plate97"is provided with yokes 98 bent to engage the rack bar 94 andto partially encircle the same.
The' plate 96is provided Witha'fiange 99 through the-casing is a. shaft'103 and mounted rigidly upon'this shaft is agear Wheel 104, the teeth of which mesh With the teeth 95 or" the rack bar94. A. ratchet Wheel is also mounted rigidly upon the Shift 103. i A yoke 106 having the form indicated in Fig. 13, is provided with "a hole 107 through which the shaft103 extends. This yoke carries a pinIOS, and; journaled upon the latter is afl'ever 109. This lever carries a tooth 110 integral'with it andadapted to engage-theteeth-of the ratchet ii heel 105. The yoke 106'is: provided 'With'a lug- 1'11 integral With it and extending over thelever 109 so as to serveas" a limiting stop therefor. A spring 112* made ofa single piece of Wire is mounted upon the yoke 106 by aid ofascrew 113;: this' spring engaging'one edge of the yoke andalso engagingthe'lever 109. The Wire 5la fteremerging fromthe sheath 54 is secured to a fastenin'g 114'carried by the yoke-106. AWiI'Qi spring=115 (see Fig. 8)."is "secured in position by- 'a screw: 116'. and engages the lower edge of the inc its
plate96. The-upper endof this wirespring bears against'the screw 108 and thus tends to maintain'thesyoke 106 in its extreme position to the left according to Figs. 8 and 9. The tension of thespring115 by its effect upon the yoke 106, as just Tstated, causes theWire 51to be' norinallyfdrawn tight-that is," the Wire is always under tension. I r A i The'operator by" raising theouter or free end of the lever 109 can disengage the tooth 110 from the ratchet Wheel 105; as indicated in FigJ'IO, and thisbeing done 'the casing andpartscarried by it'may slide eitherup or down asdesired and thus adjusted in. any Vertical l position Within E the limits of its travel. -E'a ch time the" wire 51 is drawn to the rightfaccording to Fig. 8, theyoke 106 is rocked slightly in" a clock-wise direction, the lever 109isactuated in the-same direc- 109 is brought into engagement with 'the ratchet wheel 105 so as to turn the latter in a clock-wise direction according to Fig. 10, to a distance representing the distance apart of two consecutive teeth of the toothed wheel 104. A pawl 117 is mounted upon a bolt 118 and is provided with a tooth 119 for engaging the teeth of the wheel 104. This pawl is engaged by a spring 120, the latter being secured upon a bolt 121, as may be understood from Fig. 10. A sheet of copy is shown at 122 and is mounted upon the copy holder plate 121 in any approved manner.
The operation of my device is as follows: The parts being assembled and arranged, as above indicated, the operator shifts the sleeve 41 upon the arm 36 into any one of a number of predetermined positions. associated with the notches 40, the position selected being dependent upon the length of the line spacing desired for the indicator to follow upon the copying plate 21, that is to say, the line spacing to be indicated upon the copy is made single, double, triple, etc., according to the manner in which the copy was originally prepared. If the line spacing of the copy is very Wide the sleeve 41 is shifted correspondingly further to the left according to Fig. 2. The lever 109 is now raised, and the casing of the indicator is slid up or down along the rack bar 94 until the arm 77 is brought into proper registry with the first line of the copy.
If it be desired to have the pointer 88 follow the copy letter by letter, as indicated in Fig. 7, the pointer 88 is brought directly below the first letter or other character to be copied. The plate 87 is adjusted relatively to the chain 62, if any adjustment be needed. For this purpose the operator presses upon the bolt 92 or upon the nut 95 (see Fig. 15) so as to loosen the chain 62 and then by moving the plate 87 to the right or left the pointer 88 is brought into proper registry. If further adjustment of the cable 62 be desired it can be accomplished by shifting the position of the bolt 59, this being done by simply turning the nut 60 (see Fig. 6) as elsewhere explained. These steps being performed the pointer 88 indicates not only the first line of the copy, but also the first letter of the line to be copied. The typewriting machine is next operated in the usual manner. Each time a key 25 is depressed so that the carriage of the typewriter moves to the left according to Fig. 1, to an extent representing the space between two consecutive letters being copied, the chain 62- is fed into the tubular sheath 68, the tension of the chain being taken up at the opposite end of the chain by the winding drum 84, as above explained, this drum being turned by the spring 85. The line being finished the operator shifts the line spacing lever 83 to the right according to Fig. 1. This causes the arm 36 to swing andthe wire 51 is pulled to theleft according to Fig. 1 and then relaxed. The wire at its other end (see Fig.v 8) thus pulls upon the bolt 114 and causes the yoke 106 to rock in a clock-wise direction according to Figs. 8, 9 and 10, so that the ratchet wheel 105 is turned one step in a clock-wise direction, as indicated by the arrow in Fig. 10. This causes the toothed wheel 104 to turn to a sufiicient extent to lower the casing relatively to the rack bar 94. The arm 77 is thus lowered so as to bring the pointer 88 into registry with the next line. Each time the carriage of the typewriter reaches the limit of its travel to the left and is brought back, in the conventional manner, to its starting point, the corresponding movement of the chain 62 causes the plate 81 and pointer 88, together with the' mechanical parts carried by the plate 81, to be shifted to the left according to Fig. 7, so as to be in position to start indicating the letters of a new line.
It will be noted that while the line spacing of the typewriter may, by the lever 32, be gaged within conventional limits this gaging is independent of the line spacing of the attachment for the copy holder which iscontrolled, as above explained, by the position of the sleeve 41. Such being the case the line spacing of the typewriter may be single double or triple and the line spacing of the copy holder may be the same as that of the typewriter, or may be different from it as desired. For instance the typewriter may be adjusted for double spacing and the typewriter attachment for the copy holder may be adjusted for either single spacing or double spacing.
While I show the parts mounted as here indicated I do not limit myself to this precise arrangement, neither do I limit myself to the exact details of construction shown, as variations may be made without departing from the spirit of my invention, the scope of which is commensurate with mv claims.
