SPECIFICATION forming part of Letters Patent No. 653,934, dated J' uly 1'7', 1900.

Application led November 28, 1899. Serial No. 738,552. (No model.) I

subject of the Queen of Great Britain, resid;

ing in the city of New York, county and State of New York, have made certain new and' useful Improvements in Page-Printing Tele graphs, of which the following is a speciiication.

My invention consists in combining a recording instrument having a series of independently-movable character-levers, an electromagnetic perforating instrument, and a tape or strip of suitable material, like paper, which passes through'the perforating and recording instruments in succession and providing means for advancing said tape the extent of a section or letter-space at atime through the recording instrument andthe extent of a subdivision of such section or letter-space ata time through the perforating instrument. The perforator is connected with either a manual or an automatic transmitter at a distant station by a main-line telegraph-wire, and a suitable mechanical actuating device is provided whereby the perforated tape is enabled to operate the typewriter or similar instrument.

The object of my invention is to transmit news and information telegraphically and deliver it in the form of a printed page, employing as the recording instrument a typewriting or type machine of any of the wellknown forms in common use.

At the receivingstation the type-macl1ine is provided with a series of independently-movable keys, each of which when actuated imprints a letter or character. To operate the type-writer, l em ploy an actuating device consisting of a series of notched bars or combs arranged compactly in parallel order having a capacity for reciprocating motion, the operating power being supplied by any suitable form of motor, such as an electric motor. These reciprocating combs are controlled by 'a perforated tape, of paper or other suitable material. The tape is divided into a series of successive longitudinal sections-say onehalf inch inl length. Each section represents a letter or character and is divided into a predetermined number of elemental parts-say five. Each such subdivision is either perforated or non-perforated. The perforations are arranged'in a single right line, and the `rela-tive location of one or more perforations in any section determines the letter'or character. The tape is moved along section by section-say one-half an inch at each stepacross the ends or terminals of the reciprocating combs of the actuator. The actuator operating to press the perforated slip into contact with the ends of said combs forces one, two, or more ofthern to take the desired position, properly alining the slots -in the edge of the combs to permit the immediate subsequent operation of the desired one of the series of type-bars of the machine whereby the letter is imprinted. The transmitter, either manual or automatic, located at the distantstation throws upon theline shorteurrent impulses, which operate an electromagnetic perforator at the second station. The tape is fed along through the perforator step by step the length of a subdivision at each step, and the act of perforatin g and spacing is the result of a single currentimpulse of either positive or negative polarity. I employ current impulses that are either positive or negative, separated by a short space or break. At the receivingstation there is located an electromagnet, preferably in a local circuit, operated by a neutral relay in the main line. The local magnet operates a pawl taking into the teeth of a wheel located on ashaft carrying astarwheel, the teeth ofwhich are located coincident with the feed-holes in the paper tape. The armature of the local magnet is springretracted, and a bar carried by it is in position to engage a simple form of paper punch or perforator. There is a linger capable of being projected in and out between the end of the bar and the end of the punch. lVhen this finger is withdrawn, the armature fails to engage with the punch and the paper'is advanced one step while the perforatoris not operated. This linger or intermediary is controlled by a polarized electromagnet in the main-line circuit. A series of makes and breaks of negative polarity operate the stepby-step mechanism, and the paper is fed along without perforating, while one or more positive current impulses project the nger between the armature and punch and oper- IOO `ing the parts in another position.

The accompanying drawings illustrate my invention.

Figure 1 is an elevation of the'type-writer with the actuator in position for operating or controlling it, the electromagnetic punching apparatus at the receiving-station,and a form of manual transmitter at the sending-station. Fig. 2 shows the arrangement of circuits and apparatus; and Fig. 3 is a section of the tape perforated to record a single Word, combined with the positive and negative impulses and breaks employed in its production. Fig. 4is an end elevation of the actuator applied to a type-writer. Fig. 5 is a front elevation of the same. Fig. 6 is a sectional plan view on the line 4 4, Fig. 5. Fig. 7 is a sectional front elevation of the same on the line 5 5 in Fig. 4. Fig. 8 is a transverse section of the same on the line 6 6, Fig. 7. Fig. 9 is a crosssect-ion of the actuator applied to a typewriting machine, the section being taken on the line 7 7, Fig. 5, and showing a striking device employed as just beginning to operate. Fig. 10 is a similar section showing the striker as operated. Fig. 11 is an enlarged sectional front elevation of a portion of the actuating device to clearly illustrate the reciprocating carriage and the tape-feeding mechanism employed. Fig. 12 is a transverse section of the same on the line 11 11 in Fig. 11. Fig. 13 is a like section of the same on the line 12 12in Fig. 11. Fig. 14 is a similar section of the same on the line 13 13 in Fig. 11. Fig. 15 is a like section of the same on line 14 14 in Fig. 11. Fig. 16 is a sectional plan view of part of the tape-feeding mechanism in position, the section being on the line 15 15in Fig. V11.. Fig. 17 is a similar view, but show- Fig. 1S is a diagrammatic view of certain cams employed. Fig. 19 is a sectional front elevation showing the carriage and the feeding and controlling devices in one position. Fig. 2O is a similar view of the same, but showing the parts in another position.

Referring to Fig. 1, T is a type-writer or type-writing instrument having a suitable platen and a series of type presented at the recording-point by the operation of a series of key -levers f., respectively. The typewriter T is located upon a frame f, forming part of the actuator A. This actuator comprises a series of notched bars or combs arranged in parallel relation and capable of taking a reciprocating motion individually and collectively, the ends or termina-ls being pointed and presented at the rear of the feedwheel W', around whichrthe tape e, having a series of central feed-holes 71., passes. The Wheel W has a series of pins or projections in its periphery spaced to present themselves coincidently with the feed-holes h. Motive power is supplied by any suitable motor,which may be either manually operated or driven by any known power. Such a motor is connected to the shaft carrying the driving-wheel D, which is geared to the cam-shaft C, through which the operation of the actuatoris eHected. There is a series of parallel levers L arranged side by side transversely above the combs, and each of the bars L is connected with a key-lever l.; through some flexible connecting device, like o, which passes around suitable pulleys, substantially as shown. The levers L are allowed to drop into eective operative position whenever the paper tape in its progressive movement section after section has allowed the arrangement of the combs in such a position that a series of notches, one in each comb, presents itself to one of the series of levers, and when this occurs that particular one of the series of levers L which is over a completely-alined series of slots in the combs is allowed to drop and through the intermediate mechanism operates its key-lever 7c and aletterisimprinted. The actuatoris mounted on a suitable base F, carrying standards 2 for supporting a table or bed-plate 1, on which are mounted to slide longitudinally assembling members, preferably in the form of combs 48, five in number, and controlled by 4a tape e, fed intermittently by a feed mechanism B, located on a reciprocating carriage 9 for moving the tape to and from the combs 48and actuating the same according to the conduction of the tape, as hereinafter more fully described, said combs controlling the levers L, which in turn are connected with the corresponding parts of a type-writing machine.

The message on the tape is formed by groups of elements, of which each group represents a letter or character, so that when a group of elements assembles the corresponding combs the corresponding lever L will actuate the key representing the group of elements on the tape active at the time. Each groupv of elements, as shown, contains five elements, represented either by apertures or spaces. By having the elements in each group of a like number each letter or character occupies the same space on the tape, and the intermittent feed given to the tape by the feed mechanism B corresponds to the length of the space occupied by a single group, so that the combs corresponding to the group active at the time are actuated for actuating the corresponding lever L. Owing to the uniformity of the feed of the tape and the equal spaces occupied by the group of elements it is possible for the groups of elements to be placed one after the other without intervening spaces and Without danger of error. l

The combs 48 are provided at the ends adjacent to the carriage 9 with pins or fingers 51, adapted to be engaged by a group of elementary apertures and spaces on the tape asl the latter is moved bodily with the carriage to the right. vWhen this takes place, theV IOO IIO

combs, with pins registering with apertures or perforations, are engaged by the latter and remain dormant, while the pins in register with the spaces are engaged by the solid parts of the tape and are shifted by the latter to assemble such combs and bring their slots in register with each other for the corresponding lever L to drop in such registering slots.

On the bed-plate 1 is a slideway 3, and from the said bed-plate depend hangers 4,in which is journaled a shaft 5, which may be rotated by any suitable means. I have here shown it as provided with a pinion 6 for engaging with a driving-gear D, which is provided with a crank, so that it may be operated manually; but said shaft 5 may be driven from other suitable machinery by gearing or beltand-pulley connections. Extended from one end of the bed-plate 1 is a guideway 8 for the reciprocating carriage 9 to slide on, said guideway consisting of plates secured to brackets 110, projected from the bed-plate 1. The inner edges of these plates enga-ge in grooves on each side of the carriage, so that While the carriage may reciprocate back and forth it is restrained from any other movement.

Mounted on the carriage 9 are perforated plates 111 and 112, between which the tape e is designed to pass, the perforations in the plates 111 and 112 being designed to act as guides for the passage through the tape-perforations of the fin gers 51, extending from the controlling-combs 48, as previously mentioned. The plate 112 also acts as asupport for the tape, while its solid portions are thrust against the corresponding fingers 51 of the said combs 43. On the ends of the plates 112 are vertically-

disposed rollers

114 and 115, and rearward of said plate 112 are guiderollers 116 and 117, Figs. 11, 12, 13, 14, and 15. These guide rollers 116 and 117 are mounted, respectively, in brackets 11S and 19, held on a bar 20, adapted for adjustment transversely of the carriage, and for this purpose I employ set-

screws

21 and 22, engaging tapped apertures formed in

arms

123 and 124, extending from said bar 20, and the inner ends of these set-screws (see Fig. 13) im pinge against the sides of the carriage. Obviously by manipulating these screws the rollers 116 and 117, and therefore the tape, may be adjusted. The object of providing for this adjustment of the guiderollers 116 and 117 transversely of the carriage is to permit of minute adjustment of the tape and which adjustment may be necessary to cause the elementary perforations to properly aline with the lingers of the combs 43; but this adjustment once made rarely or never needs changing. Aspring-guide 212 is held on the carriage, straddles the plate 111, andserves to hold the tape against the face of the plate to prevent accidental shifting of the tape during the time the tape is active for shifting the combs.

Adjacent to the roller 116 and mounted onY the sliding bar 2O is a curved shield-plate 125,

designed to prevent buckling of the tape as it passes along under the influence of the feeding mechanism. In other words, while the tape is being fed by the feeder or star-wheel W it will strike against the concave side of the shield-plate 125 and will be directed to a basket or other suitable receptacle without danger of its folding or returning upon the star-wheel. This star-wheel or feeder W has on its periphery a series of pins 127, (see Figs. 11,19, and 20,) adapted to engage in perforations h, formed in the tape e. The star-wheel WV is mounted on a vertical shaft 29, adapted to rotate in the carriage 9, and on the lower end of said shaft 29 is a ratchet-wheel 130, designed to be engaged bya spring-pressed pawl 131, (see Figs. 16 and 17,) mounted on the bracket 110.

Reciprocating motion is imparted to the carriage 9 (see Figs. 7, 11, 19, and 20) by means of a cam-pulley C, mounted on the drivingshaft 5, said cam-pulley having a peripheral groove engaged by a roller 44, loosely mounted on a stud 45, depending from said carriage. As the cam-pulley C moves the carriage 9 toward the bed-plate of the machine the ratchetwheel 130 will of course be disengaged from the pawl131; but upon the reverse movement of the carriage a tooth of the said ratchetwheel will engage with said pawl 131, so that the star-Wheel WV will be rotated a sufficient distance to move the tape through one section. The star-wheel is held from backward rotation while the carriage is moving forward by means of a spring-pressed dog 46, mounted on the carriage and engaging with the ratchet-wheel. (See Figs. 16 and 17.)

The combs 48 are movable longitudinally on IOO the slideway 3 and are held separately in a v Vertical position by means of pins 52, extended upward from the bottom of the slideway 3 and between adjacent combs, as is plainly indicated in Fig. 7. Some or all of the combs 4S are shifted at a time to the right by the action of the tape moved bodily with the feed mechanism, and in order to insure a return movement of the combs to the left during part of the return stroke of the carriage I provide the underside of each finger 51 with a lug 95, adapt-ed to be engaged by a spring arm or 1inger 94, mounted on a block adj ustably secured to the carriage 9, so thatwhen the latter is on the return or outward movement the arms or ngers 94 engage the lugs 95 of the previously-shifted combs to return the latter to their normal position. (Shown in Fig. 11.)

The several combs 48 are provided in their top edges with slots variously placed, and the slots are designed to govern the levers 1J, mounted to swing independently of each other on a rod 53, secured in standards 54 on the bed-plate 1, said levers L being mounted to swing in fixed guideways 155 to restrain the parts from sidewise motion. The number of levers L will correspond to the number of letters containedin the machine to which my device is applied, and said levers L are de- IIO signed to have connection by means of cords or other devices with the several keys 7s of such type-machine. The levers L extend transversely of the combs 48 and are supported at their ends normally above the several combs by means of a supporting-bar 56, and they are held yieldingly against said supportin g-bar and are adapted to swing downward at the proper time by means of springs 57, connected at one end to the levers L and at the other end to a cross-bar 58, supported on a threaded standard 158, so that the tension of the springs A57 may be adjusted by nuts 258. (See Figs. 8, 9, and 10.) The ends of the supporting-bar 56 are movable in slots formed in standards 59, and said bar is moved upward by means of posts 65, mounted on the outer ends of two levers 60, rocking on shafts 6l, and said levers 60 are provided at their inner ends with rollers 62, engaging with cams 63, attached to the' shaft 5. (See Fig. 7.) As a means of adjusting the bar 56 vertically l provide step-bearings 64, adjustable through the levers 60, and these bearings are preferably made in the form of screw-bolts, which in their upper ends have depressions for receiving the lower pointed ends of the posts 65, depending from the bar 56. Forward of the supporting-bar 56 and also forward of the levers L is a striking-bar 66, mounted on the upper ends of arms 67, projecting upward from av rock-shaft 68. On the latter is arranged an inwardly-extending arm 69, carrying at its free end a roller`70, engaging the peripheral surface of a cam 71, mounted on the shaft 5 between the

cams

62 and 63. A spring 72, connected at one end to the supporting-bar 56 and at the other end to the arm 69, serves two purposes-one to depress the bar 56 and the other to hold the roller in contact with the cam 71.

Mounted to slide on each key-lever L is a tappet-rod 73, (see Figs. '9 and 10,) movable through guideways 74 on the lever L, and the outer end of said tappet-rod extends normally forward of the end of the lever to which it is attached. A stop 75 on the inner end of the tappet-rod engages against each side of the lever L, and said stops not only prevent the tappet-rods from rotating in their bearings, but also, by coming in contact with the inner bearing 7 4, prevent the tappet-rods from moving too far in an outward direction. From the inner end of the tappet-rods 73 extend cords or other suitable connections 0 around idler-pulleys 77, mounted on a rod supported in hangers 78, said cords then extending around idler-pulleys 79, supported in hangers j8O, and from these idler-pulleys 79 the cords extend to connect with the keys of the typemachine to be operated.

The tape e is fed from a roll supported in any suitable manner, and preferably it will pass through a tension device (see Fig. 6) before it reaches the star-wheel W, so as to keep said tape under proper stress. The tension device is provided with a roller 132, supported on a stem 133, extending from a base 134, attached to the main base F, and said roller 132 is prevented from revolving freely on the stem 133 by a spring 135, which surrounds the stem and engages at one end with the roller 132 and at the other end with a sleeve 36, mounted loosely on the stem 133. The tension of the spring 135 maybe adjusted by means of clamping-

jaws

37 and 38, which engage the periphery of the sleeve 36, and said jaws 37 38 are connected at one end to the base 134, and at the opposite ends they are connected to each other by an adjustable bolt 39. By the operator manipulating the nut on the bolt 39 the

jaws

37 and 38 may be caused to bear withv means of a spring 42, attached to one end of the base or to any other fixed device and bearing atits free end against the rod 4:1, as plainly indicated in Fig. 8.

The form of tape employed by me is, as shown in Fig. 3, composed of paper having a series of central feed-holes h, and when passing through the actuator this tape is stepped forward one letter-section, indicated by the distance between the transverse dotted lines, which is equivalent to one complete letterspace. The perforations which render a letter-space characteristic and which determines the letter to be recorded are arranged in a right line longitudinally at one side of the feedperforations. I divide the section or space assigned to a letter upon the tape into five elemental parts or subdivisions, and my alphabet is based upon the relative location of these perforations within the limits of a letter-space or single step of the actuatorfeeding device. In Fig. 3 l have represented the word Paris The letter P within the letter-space assigned to it is composed of a series of perforations occurring in the second, third, and fifth subdivisions of the letter space or section. The letter A is composed of perforations occurring in the first and second subdivisions of a letter space or section; the letter R, perforations in the second and fourth subdivisions; the letter 1, perforations in the second and third subdivisions, While with the letter S the first and third subdivisions are perforated. It will thus be seen that the tape is divided into a series of equal successive sections, each section being divided into anequalnumber of subdivisions, each of equal length. In transmitting intelligence telegraphically the tape is stepped along one of these subdivisions of a letter space or section at each step. The succession ofcurrents employed is shown, together with its po- IOC larity, in Fig. 3, at 30. Impulses graphically those below the line negative, and the current breaks are indicated by a space between impulses. Both positive and negative impulses actuate the spacing mechanism and serve to step the paper ahead, but only the positive impulses operate to perforate. In the preparation of this tape as the record of transmitted intelligence or as a medium in the transmission of intelligence l may employ at the transmitting-station a manually-operated transmitter if, having a series ot' independently-movable letter-bars. This transmitter has three rotating cylinders 10 11 12, geared together and rotating in the same direction at the same speed. The cylinder 11 is electrically connected with a grounded generator 13. The cylinder 12 is similarly connected with a grounded generator 14. The generators and cylinders are of opposite polarity, respectively. Upon the periphery of each cylinder there are teeth or projections, like 15. These are arranged in alternation, spaces on one cylinder being presented at the contact position simultaneously with contact-points on the other. The brushes, like 16, carried by the key-bars of t, are employed to make electrical contact. The rotating cylinder 10 is provided with a circumferential groove opening at 18. Ahook 17, carried by the key-bar, enters this groove when the bar is depressed, and the key-bar is held down during a complete revolution of the cylinders, the arrangement being such that a second key cannot be depressed while the rst key is transmitting its signal. At the receiving-station I provide a reciprocating paper-punch 23, having a retracting-spring 24E. There is a stop-screw 21 and a hollow anvil 27, against which the paper and punch are projected, and there is a guide 26, through which the punch 23 passes. The paper tape c is carried around a wheel w and is guided and controlled by the rollers r. The wheel tu has teeth or projections which are coincident with the 'central line of feedperforations in the tape. On the shaft 31, carrying the wheel w, there is a toothed wh eel 32. m is an electromagnet having an armature 34. A finger 33, carried by the armature 3i, engages the teeth of the wheel 32 and through the action of the retracting-spring s the wheel w is stepped ahead, feeding the tape c the distance of one subdivision or elemental part of a letter, as already described, and this is done upon each and every up-and-down movement of the armature 34. The opposite end of the armature-bar is in position to engage with the punch 23 and force it through the paper, provided the finger 25 is in position to act as a medium for completing the connection. If, however, the iinger25 is withdrawn, the armature-lever moves Without aecting the punch. The magnet m is in a local circuit c, containing a battery b, operated by break-points controlled by the neutral mainline relay n. The linger 25 is controlled by the polarized main-line relay p. Upon the occurrence of a positive impulse the finger 25 is carried into position, as shown in the drawings, while a negative impulse withdraws the iinger 25, carrying the relay-tongue to its opposite limiting-stop.

The operation of the apparatus is as follows: Let us assume that the last letter shown on the tape in Fig. 3 is to be transmitted-` that is, the letter S. This consists ot' a perforation in the first and third subdivisions of the letter-space. It the key of t shown were depressed and the projections shown on the

cylinders

11 and 12 presented themselves to the contacts, the result would be the perforation of this letter. The current impulses would be as shown in the line 30, Fig. 3, the impulses occurring in the following order; positive, break, negative, break, positive, break, negative, break, negative, break, or a total of tive current impulses and five breaks, the electromagnet m and the retractingspring s, connected therewith, operating to feed the paper iive steps or subdivisions of the letter or letter-section of the tape. At each positive current impulse the relayp projected the finger 25 into the position shown, enabling the armature 34, pivoted at 35, to make connection with the punch and force it through the paper, while at every negative impulse the finger 25 is withdrawn, thus preventing the armature-lever 31 from making connection with the punch. The neutral relay n, responding to every current impulse of either polarity and its succeeding break,would make and break the local circuit c five times, producing ve successive movements up and down of the armature 34, carrying the finger 33. The succession of current impulses for every other transmitted character are positive and negative, with intervening breaks; but in case of each letter the succession'of positive and negative impulses has a characteristic diiference.

The type-writing mechanism and the controlling mechanism for the same herein shown and described are shown, described, and claimed in United States Letters Patent No. 638,591, dated December 5, 1899, issued to me for improvements in actuating mechanism for key-operated machines.
