APPARATUS FOR CONTROLLING TYPE-WRITING MACHINES..
SPECIFICATION forming part of Letters Patent No. 787,875, dated April 18, 1905.
Application filed October 12,1903. Serial No. 176,663.
Be it known that I, FREDERICK (inouen CREED, a subject of the King of Great Britain and Ireland, residing at Lenzie, in the county of Dumbarton, Scotland, have invented Improvements in or Relating to Apparatus for Controlling 'lype\\"'riting Machines, of which the following is a specification.
It has heretofore been proposed to repro- IO duce in ordinary printed characters telegraphic messages received in the form of perforations in a tape by causing the perforated tape to pass through apparatus (hereinafter called for distinction a translating-machinc) 5 that is provided with a type-writer-controlling device comprising a number of notched bars or combs (hereinafter called combs) arranged parallel to one another and capable of reciprocating in the direction of their length, the position of the said combs, and consequently the operation of the type-writing apparatus, being controlled by or dependent upon the position of the perforations in the tape, which is moved in an intermittent manner through 5 the translating-machine by the engagement of a feed-wheel with a central row of accurately-spaced feel-holes previously formcdin the tape. In apparatus of this class it has heretofore been considered necessary to di- 3 vide the perforated tape into a series of successive longitudinal sections of equal length, Each representing a letter or character and divided into a predetermined number and arrangement of elemental parts, with one or more of which the perforations are to coincide, so that the telegraphic code necessarily adopted with such a machine is ditferentfrom that used in the \Yheatstone-Morse and other automatic systems of telegraphy now in com- 4 men use, in which the portions of punched tape representing different letters or other characters (hereinafter included in the term letters") are of different length and are separated by spaces that are of equal length between letters and of greater length between words. Consequently such a translating-machine cannot be used in connection with a typc-wrlteror prlntmg mechanism for reproducing in ordinary printed characters telegraphic messages from such tape.
Now this invention has for object to obviate this disadvantage, and it relates to means or apparatus whereby \Vhcatstone or other similar perforated telegraphic tape punched according to the Morse or any other similar system can be fed forward to successive extents corresponding to the punched portions of tape representing each successive letter togcther with the corresponding space --that is to say, the blank portion of tape of unit length that separates the letter from the next letter in the same word and which is hereinafter included in the term lette1" whether such punched portions of tape be of different or equal lengths. By unit length is meant 5 the pitch of the feed-holes in the tape. The perforations representing letters may be at one or at each side of the row of feed-holes, each perforation or pair of perforations being transversely opposite to one of the feed-holes. 7 In a machine or apparatus for the purpose mentionedconstructed according to this invention there is provided in connection with a tape-guiding device, a tape-feeding device, and driving mechanism feed-operating mechanism that is driven from the driving mechanism and engages the feeding device and I the extent of the feeding movement of which is variable and is controlled or determined by means(hereinafter called the selecting $0 mechanism) the action of which is dependent upon the positions in the successive portions of tape of the perforations and spaces rep-- resenting successive letters, the arrangement being such that when the said machine or ap- 5 paratus is in operation the tape will be automatically fed forward in an intermittent manner to an extent dependent upon the length of each successive letter, whether the length of the letters be variable or not. Such a ma- 9 chine or apparatus can be used in conjunction with known or other suit-able mechanism for controlling or operating, through the medium of punched tape, type-writing or type-see ting or type-casting mechanism and is specially suitable for rapidly reproducing in ordinary printed characters telegraphic messages punched according to the lVheatstone-Morse system of automatic telegraphy.
As will be obvious, a machine orapparatus to operate in the manner and for the purpose set forth can be constructed in various forms.

a a are pairs of parallel combs of the kind hereinbefore referred to that form part of mechanism for operating or controlling typewriting, type-setting, or type-casting mechanism. These combs are adapted to be moved endwise by the action of unperforated*z'. 6., blanl-portions of each successive letter in the tape I), which is moved toward and from the adjacent and pointed ends 0 and (Z of the pairs of combs at the required time by a tapeguiding device 6, carried, it may be, by an u pwardly-extending lever or pair of levers, as heretofore, or, as in the example, by a plate f, that is caused to reciprocate at the required times by the engagement of a roller 9 thereon with a cam-groove IL in a disk 70, fixed on a driving-shaft m, adapted to be operated by hand or by a motor. In connection with a tape-feeding device, such as feed-wheel a, there is provided a two-armed lever 0 that is yielding] y connected to rotary driving mechanism, such as hereinafter described, and one arm of whichviz., o is geared to the tapefeeding device 11 so as to operate the samein one direction only, and the other end of which viz. p-is geared to a suitably-guided sliding bar or feeler Q, (hereinafter called the exploring-bar,) the extent of movement of which in one direction viz. the backward or operative direction is determined by one or other of a series of stops 0, (hereinafter called for distinction back-stops,) forming part of the selecting mechanism, and the position of which is determined by the arrangement of the perforations s and spaces 6 in the tape 6, Fig. 10. The two-armed lever 0 19 may be driven from a lever (hereinafter called for distinction the feed-lever) through a leverarm and a spring that will yield and allow the two-armed lever and exploring-bar q to come to rest before the feed-lever has completed its stroke in the operative direction, but will positively return the said two-armed lever and exploring-bar to their original positions when the feed-lever makes its return stroke. In the example shown the lever 0 p is fixed to a vertical shaft a, mounted in bearings at 2), Fig. 1, and provided with a toothed wheel w, into which gears an endwise-movable rack 1, that is connected at its ends to a pair of similar lever-arms 2 and 3. The lever-arm 2 is mounted to turn upon a spindle 4, upon which is fixed a feed-lever 5, provided with an antifriction-roller 5, that engages arotary cam 6 on the driving-shaft m. The feed-lever 5 and lever-arm 2 may be connected together by a spring that will admit of the lever-arm 2 and attached parts being driven from the feed-lever, but which will yield to allow of the lever 0 p and attached parts coming to rest when necessary before the feed-lever has completed its stroke in the direction of the arrow :0, Fig. 1, as hereinbefore described. It is, however, preferred to fix to the spindle 4:, as shown in Figs. 8 and 9, the inner end of a coiled spring 7, the outer end of which is connected to the lever-arm 2, and also to fix upon the spindle 1 the lower end of a spring-blade 8, the upper end of which terminates in front of a horizontal pin 9 on the lever-arm 2, the arrangement being suchthat when the feed-lever 5 is moved by the cam 6 in the direction of the arrow .7: the spring 7 will move the lever-arm 2 in the same direction and cause the rack 1 to turn the lever 0 p in the direction of the arrow y, Fig. 2, until it is arrested by a back-stop r, the feed-lever 5, with spring-blade 8, then completing its stroke idly, and upon the feed-lever 5 being moved in the reverse direction the spring-blade 8, by acting upon the pin 9, will move back the lever 2 and attached parts to their normal position, in which they will be held by the pressure of the said spring-blade. Each end of the two-armed lever 0 79 may convenien tly be provided with a toothed segment, that-viz., l0-at one end gearing with a toothed wheel 11, adapted to drive in one di rection only,as through ratchet or clutch mechanism, the feed-wheel n. which is provided with pins or teeth or, arranged to engage in the central row of feed-holes 13 in the tape 6. In the example the wheel 11 is fixed on a sleeve 11", that carries a spring-pawl 12, Figs. 1 and 2, which engages a ratchet-wheel 12*, fixed to the spindle 12", that carries the feed-wheel n. The toothed segment 14 at the other end of the said lever 0 gears directly into a rack 15 on the exploring-bar q.
The back-stops 9', which are equal in number to the greatest possible number of spaces occupied by the perforations s, Fig. 10, in a letter, (ten in the case of Wheatstone-Morse tape,) are arranged parallel to one another and so as to be capable of moving transversely in astationary support or carrier 16 and across a longitudinal guideway 17, through which the exploring-bar [7 works and which is arranged parallel and opposite to the tape-guidingdevice w. The latter device comprises a pair of longitudinal plates arranged in a vertical or approximately vertical plane and having between them a vertical race 19, along which the tape is fed on edge, as heretofore. Extending hm'izontally through the said pair of plates are two longitudinal rows of holes 20, (see Fig. 5,) arranged to be at opposite sides of the central row of feed-holes 13 in the tape 7), the said horizontal holes being arranged in vertical pairs having the same pitch in a longitudinal direction as the pitch of the said feed-holes. \Vhen working with Wheatstone-BIorse tape, there will be ten vertical pairs of holes, as shown. Each of the back-stops w is adapted to be moved by a spring 21 across the longitudinal guideway 17, the arrangement being such that when the foremost back-stop is across the guideway the exploring-bar I] can then only move into the guideway to a distance that will enable the two-arm lover I p on its return or feed stroke to feed the tape forward to an extent eorre-spoiuiling to the length of the space between two successive letters. Corresponding to each backstop '1 are two selector-bars 22, arranged one above the other in the same vertical plane and between the tape-guiding device w and the backstop support or carrier 16. The inner ends 23 of each pair of selector-bars 22 are rounded and arranged to enter and be guided by one of the vertical pairs of holes 24) in the pair of longitudinal plates comprising the tape-guiding device If, the outer ends of each pair of selector-bars being formed with inwardlyturned projections 24;, that take behind corresponding projections 25 at the inner end or head of the corresponding back-stop r. The adjacent inner ends r and (I of the pairs of combs u of the type-writer actuating or controlling device, which are arranged at the other side of and at a short distance from the tape-guiding device 1 are rounded and similarly arranged in vertical pairs corresponding to the pairs of holes 20 in the tape-guiding device. For this purpose one of the ends viz., of the combs a of each pair thereof is bent sidewise, so as to come into the same vertical plane as the end 0 of the other comb of the pair. Each of the selector-bars 22 connected by a coiled spring 26 to a lixed frame or support 28, through which the bar 22 works and by,which it may be guided, the said spring 26 tending to move the selector-bar inward to a limited extent toward the tape 1) and withdraw the corresponding back-stop '1' from across the longitudinal guideway 17 against the action of its spring 21. The strength of the springs 21 and 26 is such that either of the selector-springs 26 can overcome the spring 21 of the corresponding back-stop when free to do so. The extent of inward movement of the selector-bar: 22 may be determined by the abutment of a shoulder 29 on each of such bars against a stop 2? on the fixed frame orsupport 28. The extent of inward movement of each comb u may be determined by a longitudinal fixed bar 11 that serves as a stop for a shoulder a on each comb. Each comb a is also formed with a shoulder u for a purpose hereinafter described.
As the length of the letters to be translated may vary, means are provided for forcing back all the combs a of the type-writer actuating or controlling device which correspond to the portion of tape following that occupied by the letter being translatedthat is to say, to produce on the combs the effect of blank tape in the said following portion. For this purpose there may be arranged between the tape-guiding device e and the set of combs u, as in the example shown, a longitudinal bar or plate 30, (hereinafter called for distinction a shutter,) that is arranged to be operated from the tape-feeding mechanism, as through a longitudinal rack-bar 31, in such a way that it will be moved backward simultaneously with and to an equal extent as the exploringbar 19, and therefore to an extent depending upon the length of the letter to be translated. The said shutter 30 is arranged to be. moved sidewise by the tape-guiding device and to act upon and move the combs endwise., the arrangement being such that the shutter will displace the combs endwise at the same moment that they would have been displaced by blank tape. For this purpose the shutter 30 is in the example arranged to slide endwise in a guideway e in the device 1 and to abut against the shoulders (1, Figs. 3, (3, and T, on those combs I! that are opposite to it and move back such combs. The normal or forward position of the said shutter 30 is such that if oscillated by the tape-guiding device I when in that position it would displace all the combs u endwise. When operated by the lover I) p from the feed-lever, as described, it will clear those combs opposite the letter to be translated, so as to allow the perforations of that letter to have their normal effect upon such combs.
To preventbackward inovementof the feedwheel/1 during the idle stroke of the twoarm lever 0 there is provided means, such as a V-shaped centering-tooth 32, Fig. 11, adapted to enter the V-shaped space between any two teeth of a wheel 33, fixed to the feedwhcel a and having the same number of teeth as that wheel, or a roller 34, Fig. 2, adapted to pass between any two of the feed-pins nou the feed-wheel u, may be used for a like purpose. The said centering-tooth 32 or roller 3a may be carried by a spring-arm 35, that will permit of its yielding to allow of the toothed wheel 33 and feed-wheel 12, or feed-wheel only, being positively driven in the forward direction.
36 and 37 are adjustable stops to limit the forward movement of the exploring-barqand the shutter operating bar 31. The stop 36 is preferablyarranged to limit the forward movement of the lever-arm p and attached parts that operate the said exploring-bar, so as to relieve such bar to a large extent of the shock resulting from the stoppage of the said arm. The stop 37 is arranged to directly limit the forward motion of the bar 31. This bar may conveniently be in the form of a rack that gears with and is driven by the toothed wheel 11, with which it is held in gear by a guideroller 38, carried by a fixed support 39, Figs. 1 and 2. To allow of the lateral motion of the shutter 30 with the tape-guiding device a without moving the bar 31 laterally and without materially affecting the proper position of the shutter by reason of the lateral movement, the shutter may be connected to the bar 31 by a spring-blade 31, Fig. 2. A fixed back-stop 4:0 is provided to arrest the backward movement of the exploring-bar (1 when all the back-stops may have been withdrawn by the letter about to be translated. A guide-roller 38, Figs. 1 and 2, carried bya fixed support 39, is provided to keep the rack on the outer end of the exploring-bar q in gear with the toothed segment 14.
The working of the apparatus is as follows: Assuming a perforated tape 7) to have been passed through the tape-guiding device a and engaged with the feed-wheel n, that the feedwheel is held at rest by the abutment of the arm p of the lever 0 2) against the stop 36 and by the engagement of the centering-tooth 32 or roller 34 with its toothed wheel 33 or feedwheel a, as the case may be, that the tapeguiding device 6 is in its normal or mid p0- sition--that is to say, is holding the tape 6 clear of the pins 23 on the selecting-bars 22 on one side and the pins 0 and (Z of the combs a on the other side that the selector-bars 22, back-stops 7', and combs a are in their inner positions toward the tape Z), and that the translated letter has been fed forward and a new one brought into position, to be translated by the movement of the two-arm lever 0 p to its normal position, limited by the stop 36, then the first feed-hole 13 in the portion of tape 6, representing the new letter, will have been brought to a point midway between or in the vertical plane of the foremost vertical pair of holes in the tape-guiding device 0. The tape-oscillating device 6 is now operated by the cam-groove 7L and roller g to move the tape toward the pins 23 of the selector-bars 22, so that those bars corresponding in position to the perforations representing the letter will not be operated upon, but that pair of selector-bars corresponding to the space included in the letter about to be translated will be moved outward by the blank tape and will permit the corresponding back-stop 9' to be moved by its spring 21 across the longitudinal guideway 17. The feed-lever 5 is then operated by the cam in a direction to cause the two-armed lever 0 p to move idly with respect to the feed-wheel n, but to cause the exploring-bar q to move backward into the longitudinal guideway 17 to an extent that is limited by its abutment against the first back-stop 9, extending across the guideway, and which therefore corresponds to the length of the letter being dealt with, the said feedlever completing its stroke without affecting the said lever 0 10, while the said exploringbar g and also the shutter-bar 31 and shutter 30, which have been moved back to an equal distance, are held at rest by the said back-stop 7'. To prevent the back-stop being prematurely drawn back, it may be formed with a hole, into which a pin on the end of the exploring-bar then takes. While the two-armed lever 0 p, exploring-bar q, and shutter-bar 31, with shutter 30, are thus held in their backward positions the tape-guiding device 0, together with the shutter 30, are moved toward the pins 0 and cl on the combs a, displacing all that are opposite to blank spaces in the letter, and are opposite the shutter and allowing those which correspond to the perforations s in the letter to remain in their inner position. The rearrangement of the combs 0 thus pro duced permits the printing or type-setting machine to be operated to print or reproduce the letter. The tape-guiding device a is now moved back by the cam-groove 7b to its midposition, whereupon the feed-lever 5 is moved in the opposite direction to cause the twoarmed lever 0 p to operate the feed-Wheel n and feed the tape, with the letter just translated, forward and bring a new letter 'into position to be translated and to return the exploring-bar q and shutter to their forward positions against their stops 36 and 37. During this movement the centering-tooth 32 or roller 34 is either withdrawn from its toothed wheel 33 or feed-wheel n or, as in the example, is forced to ride over the teeth of the wheel, which it will reengage when the movement is completed. The combs a are moved back into their normal position in the usual way before the tape-guiding device a is again moved toward them. The above-described operations are then repeated.
The comb a, the mechanism actuated or controlled thereby, and the type-writing, typesetting, or other mechanism to be used therewith for reproducing in ordinary characters the letters punched in the tape may be of any known or suitable construction. In the example shown the combs a are formed with a series of notches 41, (see Figs. 6 and 7,) and across them extend a series of bars 42, that are kept parallel to each other by a pair of combs 13, through which they can work endwise. Each bar 42 is jointed at its outer end to one arm, 44:, of a bell-crank lever pivoted at 45 to the frame 46 of the machine and the other arm, at. of which may be connected, as indicated diagrammatically in Fig. 12, to a key-lever i8 for actuating, as through a link 49, the corresponding type-arm of a type-writing machine, the paper-cylinder of which is indicated at 51. The bars 42 are pulled downward by springs 52 onto the combs u. the recesses L in which are so formed and arranged as to produce differentcombinations for the different letters to be reproduced and so that when some of the combs are pushed outward by blank portions of tape some of the recesses in the several combs will come opposite each other, so that the particular cross-bar l2 corresponding to the letter being translated will be allowed to fall into thejuxtaposed recesses, and thereby bring it into the path of an oscillating bar 53, which will move the said cross-bar l2 endwise and operate the typeavriting or other mechanism, as above indicated, in a known manner. The combs are pressed inward by wire springs 54:, Fig. The oscillating bar 53 is fixed to and oscillated by the upper arms of bellcrank levers carried by a pivoted rod and the other arms, 55, of which are arranged to be acted upon by cams 57 on the drivingshaft 11/. The return of the combs displaced by blank portions of tape is insured by a bellcrank lever 58, pivoted at 59 and operated by a cam 60 on the driving-shaft 1/1. Each crossbar 42 and attached parts are returned to their normal position when relieved of the pressure of the oscillating bar by a spring 4A". Each cross-bar 4:2 after falling into a juxtaposed set of recesses 4E1 in the combs is lifted out of the recesses by a lifting-bar 61, that is alternately raised and lowered by cams (52 on the driving-shaft 11/, acting through levers 63 and downward extensions 6% of the liftingbar, which are guided by links 65. One of the cross-bars say 42, Fig. 3 serves as a spacing-bar to actuate the spacing mechanism of the typeavriting or other machine when a blank portion of tape or a blank portion of 'tape and the shutter 30 displace all the combs u endwise. Other bars may be used in the same way for other special movements of the printing mechanism.
Apparatus according to this invention can be used with perforated tape of various kinds, whether such tape be telegraphic tape or tape punched directly by a perforating-machine worked by hand or otherwise and not intended for telegraphic purposes.
As will be obvious, the details of construction can be variously modified without departing from the essential features of the invention.
