MACHINE FR PRODUCING PERFORATED TELEGRAPH-PAPER.

SPECIFICATION forming part of Letters Patent No. 71 1,660, dated October 21, 1.902.

Application filed June 12. 1901.

To all whom it may concern:

Be it known that I, GEORGE HAsTINGs HACK- ETT, a subj ect of His Majesty the King of Great Britain, residing at North Sydney, county of Cape Breton, Province of Nova Scotia, Canada, have invented certain new ,and useful Improvements in Machines for Producing Perforated Telegraphic Paper; and I do hereby declare that the following is a full, clear, and 1o exact description oftheinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is a machine for perforating or punching paper for the automatic transx 5 mission of telegraphic messages by the Wheatstone recorder or other systems ot telegraphy on cable or aerial lines.

It is Well known that telegraphers stationed in certain offices are required to punch or perforate messages upon strips or rib bons of paper in accordance With the weil-known electric telegraphic characters, with this-important distinction-t. e., the dots of the telegraphic alphabet are distinguished from the z5 dashes by arranging the former above a real or imaginary line of demarcation, while the latter appear below such line.

The chief and important purpose of the present invention is to provide a machine in which all the perforations representative of the dots, dashes, or both, required to forni a complete letter, figure, or other character may be produced with a space between it and the following letter, character, figure, &c., of the telegraphiccode may be produced by the depression of a single key or elementin much the same way as the operation of type-writing machines. z l

A further object of the invention is to pro- '40 vide automatic vmeans-for producing a central line 0f holes or perforations'in the paper simultaneously with the formation ot' the character-indicating perforations, such central lineot' perforations serving as the line of demarcation for the dot and dash representations of the character'and as a means for the engagement of the feeding element ofthe automatic transmitter and also of a like element of my improved perforating-machine.

A further object of the invention is to im- 5o 4prove the perforating-machine inminor deablefkeys or elements, each arranged to have operative connection with one or more punches ot' eitherl group, according to the number of Vdots and dashes which is required to be produced in the ribbon or strip to form the letter, ordinal, or character of the usual telegraphic code.

The invention further consists in a group of feed-hole punches mounted on a common carrier for simultaneous movement and disposed in cooperative relation to the characterpunches of the two groups and adapted to be l positively actuated by one or more of such character-punches of either group.

The invention further consists of a ribbon or strip-feed mechanism operable automatically by the character-punches or the feed-hole 8o punches and capable kof imparting a variable feed to the ribbon or strip according to the number of dot and dash perforations in the letter or character of the code My invention further consists in the novel combination of mechanisms and in the construction and arrangement of parts,which will be hereinafter fully described and claimed.

In Athe drawings hereto annexed, forming a part of this specification, Figure lis aplan view of my perforating-machine with a portion of the housing or casing omitted in orderto show some of the operating parts. Fig. 2 is a front elevation with Va part of the key-guide plate broken away. Fig. 3 is an inverted or bottom plan view of the machine. Fig. 4 is a longitudinal sectional elevation through the machine in the plane of the dotted line 4 4 on Fig. 1. Fig. 5 is an enlarged sectional plan view through the punch mechanisms and the feed mechanism in the plane of the dotted line 5 5 on Fig. 4. Fig. 6 is an enlarged sectional elevation in the plane of the dotted line 6 6 on Fig. 5 looking in the direction of the arrow. Fig. 7 is a vertical cross-section on the line 7 7 of Fig. 6 looking in the direction of the arrow. Fig. 8 is a detail cross-section on the line 8 S of Fig. 6. Fig. 9 is another detail cross-section on the line 9 9 of Fig. 6. Fig. 10 is a sectional plan view of the feed mechanism in the plane of the dotted line 10 10 on Fig. 1l. Fig. 11 is a vertical transverse section through the feed mechanism in the plane of the dotted line 1l 1l on Fig. 10. Fig. 12 is a sectional plan view in the plane of the dotted line 12 12 on Fig. 6, taken through the row of die-openings for the feed-hole punches. Fig. 13 is an enlarged sectional plan View in the plane of the dotted line 13 13 on Fig. 11, showing one group of the character-punches advanced to its operative position. Fig. 14 is a fragmentary view of a strip or ribbon of paper perforated by a machine in accordance with my invention and illustrating the dot and dash perforations and the central row of feed-holes to indicate the letters a, b, c, and d of the Morse code. Fig. 15 is a front view illustrating the group of central feed-hole punches and the two groups of upper and lower character-punches in ord er to more clearlyillustrate the relation or arrangement thereof.

The same numerals and letters of reference denote corresponding parts in each of the several figures of the drawings.

5 designates the frame, casing, or housing, which may be of any desired or approved construction, although in the embodiment of the invention represented by the drawings it is shown of elongated rectangular shape. Within this housing are supported the transverse bridge-bars 6 6, the same arranged in horizontal positions near opposite ends of the casing and secured firmly to the sides thereof by approved means. These bridge-bars are preferably arranged in rear of the bank of keys. They are spaced apart a sufficient distance to accommodate between themselves a number of key-actuated rock-shafts 91 59. They are arranged in the same horizontal plane, and they are provided with a series of vertical slots 7. These slots are arranged in the same horizontal and vertical planes in the two bars t G, and each slot is deep enough to accommodate two of the character-punch slides. (See Fig. 7.) A confining-plate 7 is secured to the top edge of each bridge-bar, so as to extend across the open upper ends` of the slots 7 therein, and this plate extends across the upper group of slides ct b c d e, as will hereinafter more fully appear. The framework of the apparatus or machine is completed by the provision of key-guide plates 8 which project horizontallyfrom the front side of the housing, and by the employment of a boxing 9, which is disposed at one end of the housing 5, said boxing serving to inclose the operating parts forming the feed mechanism for the ribbon or strip which is to be perforated by the groups of punches in accordance with the characters of the telegraphic code. The key-guide plates S S are disposed in horizontal positions one above the other and in parallel relation, and these plates are firmly secured to the housing, whereby the plates are adapted to serve as the supports for the slidable keys. These keys are indicated by the

numerals

53, 54E, 55, and 56, and they are arranged in two series, the keys of each series extending longitudinally along the front of the machine, while the keys of one series are disposed in a horizontal plane below the keys of the other series, thus arranging the keys in a bank at the front of the machine. I Will have it understood, however, that the fralnework of the machine may be arranged to include the boxing 9 as an integral part thereof and within the limits of said framework and that the means for supporting the keys may be varied in any manner suggested or approved bythe skilled constructor, so as to promote the convenience of the operator in the manipulation of the machine or for any other canse whatsoever. It is evident that the keys may be disposed in a manner similar to the keyboard of a type-Writing machine; but this is optional. A practical Working machine which 1 have constructed and operated includesa total of thirty-eight keys, each having a rock-shaft .()1 or 59 combined operatively therewith; but I have reduced the machine to a sim ple condition by the provision of means which enables me to employ a series of ten character-punches, the same adapted to be operated according to certain permutations or combinations with said key-actuated rock-shafts. The character-punches are divided into two groups, arranged to represent, respectively, the dots and dashes of the code, and, as hereinbefore explained, 1 have found it convenient to follow the established plan of punching the dot-perforations in the ribbon above the line of demarcation therein, while the punches which represent the dash-perforations operate on the ribbon or strip to make said dash-perforations below the line of demarcation. The punches of the two groups are mounted individually onslides, and the slides for the upper series of punches Sl 82 S3 S4 S5 (see Fig. 5) are indicated by the reference-letters a b c CZ e. (See Figs. 7 and 9.) The lower group of character-punches is indicated by the numerals S6 S7 S3 89 90, (sce Figs. l2 and.15,) and said punches of the lower group are carried by the slides f, g, 72, t', and j. The slides constituting each group are disposed in the same horizontal plane. The slides forming the lower group f to j, inclusive, are arranged in the slots 7 of the bridgebars 0 6, so as to rest upon the lower ends of the slots and be thereby supported in said bridge-bars, and the slides of the upper group IOO IIO

a toe, inclusiveoccupy the upper portions of the slots 7 in the bridge-bars, whereby the slides ofthe upper series are disposed to rest upon the slides of the lowerseries. (See Fig. 7.) Each slide is movable Vlongitudinally in the bridge-bars without affecting either of the other slides, and it will thus be seen that each slide is capable of a longitudinal reciprocatory play individuallyY or independently of either of the other slides. The slides extend practically the full length of the frame or housing, so as to lie over the entire series of thirty-eight rock-shafts,` and these slides are thus disposed to have slidable relation to each and all of the rock-shafts, which makes it possible for intermediate devices to actuate either of the rock-shafts with any one or more of the upper and lower groups of slides. The slides are adapted to be individually or collectively impelled in a forward direction by the operative connections from said slides to the rockshafts but the slides are returned back to their normal positions by the action of a suitable impelling-spring, connected operatively with the cross-head 65, (see Figs. 1, 4, and 13,) said slides being individually provided with stop pins or 'lugs 10, which are arranged to impinge against the bridge-bar 6, and thereby limit the rearward movement of the slides under the action of the retracting-springs 65a. These character-punch slides are disposed in peculiar relation one to the other, as represented by Figs. 1, 3, 4, 5, 7, and 13, for the purpose of accommodating the means that operatively connect the rock-shafts with the slides. The middle 'slides c h of the upper and lower groups are straight throughout their length. The slides b d of theupper group and g L of the lower group are bent at points just in advance of the bridge-bar 6, as indicated at 11, in order to make the front portions of the slides lie very close together, while those portions of the slides which lie over the rock-shafts 91 59 are spaced apart and in parallel relation, so as to accommodate the studs on the slides and the lingers on the rock shafts, and, furthermore, the outermost slides a e of the top groupandfj of the bottom `group are also bent inwardly, as at 11a, in` order to bring their front ends in close parallel relation to the corresponding ends of the other slides and enable the portions that extend over the rock-shafts to be spaced laterally and parallel to the other slides of the groups, whereby said slides a c fj are also arranged over the rock-shafts for the fingers on certain of theshafts to have operative relation to studs on said designated slides. This construction and arrangement of the slides permits the large number of iingers required for the entire series of rockshafts to be disposed in Working relation to` a small number of slides, and, furthermore, the closely-arranged bent front portions of said slides enable the character-punches of the two groups to be compactly disposed with relation one to the other for operation on ya like staggered order. The two groups of char-4 acter-punches and a third group of punches adapted to form the feed-holes or the line of demarcation in the paper or ribbon are operativelyfitted in acommon die-block 12, the latter being arranged in a horizontal yposition within the compartment of the boxing 9, and preferably secured to the front end wall of the framework 5. This die-block is provided with a central row ofsix die-openings 13, adapted to receive the group of feed-hole punches 7576 77 78 79 80. (See Fig. 12.) It is furthermore provided with an upper row of die-openings 14, adapted to receive the tive dot-forming character-punches 81 to 85, inclusive, and nally the die-block is Yformed with la lower row of die-openings 15, iive in number, and

disposed for the reception of the dash-form-` ing character-punches 86 to" 90, inclusive.

16 designates a die-plate which corresponds in formv and size to the die-block 12 and is secured to the inner side thereof in the position shown by Figs. 5, `6, 11, 12, and 13,"said die-plate being provided with rows of holes 13a, 14a, and 15a, which are arranged in positions corresponding to the rows of

holes

13, 14, and 15, respectively, in the die-block, whereby they punches are adapted to pass when advanced from theholes of the dieblock into the holes of the die-plate. (See Figs. 12 and 13.) In the face ofthe dieblock,to which the die-plate 16 is secured, is provided a space, channel, or groove 17, through which the ribbon ,or strip of paper isr adapted to bek fed in the manner represented also by Figs. 12 and 13, and across this space or channel are adapted to play the character and feedhole punches, whereby the paper fragments removed from the ribbon or strip by the operationrof the punches, due to the process of perforating the-paper, are carried through the Vholes in the die-plate and discharged into the compartment of the boxing The dieplate 16 is provided with a recessor slot'18,

IOS

IIO

which extends through the die-plate from the series of holes 14 to one edge of the plate, as indicated in Fig. 12, and a recess 13a is also formed in a Vpart of thevdie-block in a Y similar back slide 20, and in these slides are formed the slots 21 21, respectively, which slots lie in the transverse plane of the ribbonchannel 17 in the die-block, whereby the strip or ribbon of paper may be drawn from a spool or reel or other source of supply may pass through the boxing 9 and the ribbonchannel17 of the die-block, and it may be engaged by the feed-wheel, thus presenting the ribbon in position for the operation of the punches thereon, and allowing the ribbon to continuously pass through the machine.

I will now proceed to describe the preferred embodiment of the feed mechanism, which is arranged to advance the ribbon or strip as rapidly as it is perforated and is operable automatically with either group of punches or with the individual punches of the character-forming elements of the machine.

A vertical feed-shaft 22 is journaled in snitable bearings 23 at its upperand lowerends, (see Figs. G and 11,) one of the bearings being secured to the bottom of the boxing 9 and the other to the top thereof. The feed-wheel 24 is made fast with this shaft, and it is provided with a multiplicity of pins or studs 25, said feed-wheel and the shaft being arranged in position relative to the die-block for the pins 25 to sweep through the slot 1S and the recess 1S and to engage with the feed holes or perforations which are formed at the middle of the ribbon by the operation of the feed -hole punches 75 to SO, inclusive. A ratchet-wheel 26 is also made fast with the feed-shaft 22, being arranged, preferably, below the feed-wheel 24, and this ratchet-wheel is rotated intermittently bythe action of a pawl 46, which is mounted on a reciprocatory feed-rod 27. (See Figs. 5, 6, 10, 11, and 13.) This feed-rod 27 is disposed in a horizontal position, so as to pass through a guide-block 2S, which is secured to the front end wall of the casing 5, whereby one end portion of the feed-rod is disposed in a compartment of the boxing 9, while the other portion of said feedrod lies in the casing 5, preferably below the group of character-punch slides. rlChis feedrod is supported partly in the casing 5 by means of a bracket 29, which is fastened to the front end wall of said casing and has a sleeve 29, in which the feed-rod is loosely tted, and said feed-rod is provided with the stop-collars 30 30, (see Fig. 9,) which are disposed on opposite sides of the sleeve 29a of the bracket, said collars serving to permit the feed-rod to have a reciprocatory movement within the required limits. The feedrod is provided with a threaded rear extremity 31 for the attachment-of the cross-head 70, which is adapted to be operated by a stopcollar 73 on a reciprocatory rod 61, that is actuated by the spacing-key, as will hereinafter more fully appear, (see Fig. 6,) and to the rear threaded extremity of this feed-rod is connected a link 32, which extends over the series of key-actuated rock-shafts and to the other end of the framework through an opening in which said link is arranged to pass in order that it may be connected to the upper extremity of a bell-crank lever 33. (See Fi". 4.) Said lever is fnlcrnmed at its angle, as at 34, to the outside of the casing 5, and to the long arm of this bell-crank lever is connected a powerful spring 35, the same having its other end attached to the framework, as at 37. The energy of the spring 35 normally pulls the feed-rod to the right, so as to maintain the elements of the ribbon-feed mechanism in the normal position, (shown by all the figures of the drawings except Fig. 13,) although the feed-rod 27 occupies an operative relation at certain times to the cross-head 65. Said feed-rod within the compartment of the boxing 9 is formed with a lateral offset 38, (see Fig. 10,) and said feed-rod has an extension 39, which is disposed alongside of the ratchetwheel 26. Said feed-rod extension is provided at a point near the crook or bend with a collar 40, and it carries a bent check-finger 41, the latter being formed at its heel with a socketed enlargement 42, that is fitted on the extremity of the feed-rod extension 39, said enlargement supporting a binding-screw 43, that is adapted to impinge the feed-rod, and thereby clamp the check-linger rigidly to the feed-rod extension. Between the collar 40 and the socketed enlargement 42 on the feedrod extension is loosely arranged a pawl-carrying sleeve 44, (see Figs. 10 and 11,) said sleeve being capable of a limited movement or play on the feed-rod extension between the collar 40 and the enlargement 42. The pawl-sleeve is provided on one side with a slot 45, in which is arranged the feed-pawl 46, the same being pivoted to the slotted portion of the sleeve, as at 47, and pressed, by means of a spring 48, normally into engagement with one tooth on the ratchet-wheel 26. The feed-rod extension and the pawl-sleeve are supported and guided by a post 49, which is provided with a divided bearing 49, that loosely embraces the pawl-sleeve, as shown more clearly by Fig. 11, whereby the feedrod extension and the pawl-sleeve are upheld by thepost, so as to keep the feed-pawl 46 at all times in operative relation to the ratchet 26. When the feed-rod 27 is impelled in a forward direction, either by the action of the spacing-key or by the movement of one or more of the groups of character-punch slides, the feed-pawl 46 slips idly over the teeth of the ratchet and the check-inger41 is carried away from the ratchet; but when the feedrod is pulled in a backward direction by the energy of the spring 35 the feed -pawl 46 moves the ratchet 26 an angular distance equivalent to the number of teeth over which the feed-pawl is slipped during its` forward movement, the check-finger 41 preventing any idle play of the ratchet owing to the jar which may be given to the machine by the spring 35 or other working elements ot' the apparatus. On the opposite side of the ratchet 26 from the feed-rod extension is a ICO TIO

LII

f words of the code and to make the inquiry-' fixed arm 50, which is secured to the front end wall of the frame 5, and to this arm is pivoted a check-pawl 51, the same being held in engagement with the ratchet by a spring 52, said check-pawl preventing rotation of the ratchet by the frictional engagement of the feed-pawl 46 therewith during the forward movement ot' said feed-pawl with the feed-rod.

The key 53 is the spacing-key, by which and its associated parts the group of feed hole punches 75 to 80, inclusive, are actuated independently of the character-punch slides for the purpose of making the feed mechanism advance the ribbon or strip independently of the operation of either of the characterkeys when it is desired to separare letters or words of the telegraphic code produced by the perforation of the ribbon. The group of twenty-six alphabetical keys (indicated by the numeral 54) are operatively related to the character-punch slides, so as to actuate the same individually, with a view to making the character-punches produce the alphabetical telegraphic code. The key 55 is the character-key which is frequently employed in telegraphy, especially at the beginning and end of a message. The group of ten keys comprised in the reference-numeral 56 are operatively connected through intermediate devices with the group of character-punch slides in a manner to make the latter actnate the character-punches so as to produce in the ribbon the telegraphic-code signs representative of the ordinals from naught to nine, inclusive. The alphabetical and numerical keys 54 56 constitute the two series which are designated, generically, by the term characters, whereas the keys 53 55 are adapted to make the punches work so as to space the sign call for an operator at a distant station, respectively. Each key is provided with a stem that is slidablyfitted in the plates 8 8fL of the framework, and around the stem of the keys 54 55 56 are coiled the lifting-springs 57,

one of which is provided on each key-stem and.

position below the lower group of character-` punch slidesf to j, inclusive, and its rear portion is slidably fitted in an opening or slot 63, which is provided in the bridge-bar 6.

reduced and threaded at 61?', and it passes through an opening which is provided in a depending lug 68 on the cross-head 65. (See Figs. 6 and 9.) The nuts 69 69? are screwed (See Fig. 7.) This spacing-rod 61 has its front end on the threaded extremity 61606 the spacingslide and arranged to bear against the opposite sides of the lug 68 of the cross-head 65,

` whereby the front endl portion of the spacingslide is lsupported by the cross-head 65 and the spacing-slide and the cross-head are fixedly but adjustably united together. This cross-head 65 is slidably fitted in recesses 66 67,.which are formed in the opposing edges of the closely-arranged front portions of the upper and lower group of character-punch slides, and said cross-head is normally arranged at the rear portions of said recesses, so that it may be engaged by the shoulders 66? 67a of the slides forming the two groups, wherebyjon the advancement of one or more slides of one or both groups the shoulder or shoulders will press against the cross-head,

is adapted 4to be engaged by a collar 73, which is fitted on the spacing-key` slide 61 at a point in rear of the cross-head, said collar 73 having a binding-screw 74, which makes the collar fast with the spacing-rod 61. (See Fig. 6.) Furthermore, the cross-head is provided with a depending shank 70a, which is loosely ttedl on the threaded rear extremity 31 of the reciprocatory feed-rod 27, and this crosshead and the feed-rod are made fast together by the check-nuts 70h, which are screwed on the extremity 31 of the feed-rod and are disposed to bear against opposite sides of the shank 70ai of said cross-head 70.

The feed-punches 75 to 80, inclusive, are all attached to the cross-head 65 so as to lie in the Asame horizontal plane and to properly enter the series of holes 13 in the die-block, and all these punches are of uniform length, as clearlyshown by Fig.12. The upper group of character-punches 81 to 85, inclusive, are disposed in the same horizontal plane and are fastened individually to the slides of the upper group a to e, inclusive,said upper group of character-punches arranged to play inthe upper series of holes 14 of the die-block and having their front ends disposed in staggered order, as shown by Fig. 5. The lower group of character-punches 86 to 90, inclusive, are made fast withthe slides of the lower group f to j, inclusive, and they are disposed to work in the lower series of holes 15 in the die- IOO IIO

block, and they have their front ends disl clusive,are six in number,whereas each group 0f character-punches consists of live parts only, and, furthermore, the feed-hole punches are of smaller diameter than the characterpunches. The rock-shafts 91 are associated with the alphabetical and

inquiry keys

54, 56, and 55, respectively, and each rock-shaft is provided at one end with an arm 92, the same being disposed in operative relation to the lower extremity of one key-stem and said series of arms being compactly arranged, as shown by Fig. 3, in order to minimize the space. Each rock-shaft furthermore carries one or more fingers 93, and each finger is arranged to impinge orride against a stud or pin on one of the character-punch slides. The studs on the slides of the upper group are indicated by the numerals 94:, and the studs on the slides of the lower group are indicated at 95. It will be understood that the spacingkey does not actuate a character-punch slide, nor is it operatively disposed to a stud on either of the slides of the two groups. Each rock-shaft which is operated by a characterkey has a group of fingers corresponding in number to the dot-and-dash punches required to represent the letter in the telegraphic code, and said fingers ride against pins or studs which are placed ou slides of the upper and lower groups, so as to individually actuate the slides in the proper order with a view to making the dot-punches above the line and the dash-punches below the line, although all of the punches are operated simultaneously.

By reference to Fig. 14.- it will be seen that the ribbon 100 has a central row of feed-holes 101, and said figure shows the telegraphiccode letters a, 11, c, (11, the first of which, a, is made by one dot-perforation above the line and one dash-hole below the line; the second letter, b, by three dot-holes above and one dash-hole below the line; the third letter, c,7 by two dot-holes above the line and two dash-holes below the line, (be. It is evident, therefore, that the rock-shaft 91, which is actuated by the letter-key CL, must have two fingers 93 arranged to press against a stud 94 on one of the upper group of slides and one stud 95 on one of the lower group of slides, so as to make the punches operate in the sequence of one dot and a dash, as in the telegraphic code. The rock-shaft for the letter-key Z) must be equipped with a series of four lingers 93 arranged to press forward against the studs 9a on three of the upper group of slides and one stud 95 on one of the lower group of slides in the order of making a dash and three dots. The rockshaft for the letter key c must also be equipped with fourlingers 93 so arranged that they will actuate studs 94 ou two of the upper group of slides and two studs 95 on two of the lower group of slides, so as to make one dash-perforation, one dot-perforation, another dash-perforation, and another dot-perforation in proper sequence or order. The rock-shaft for the letter-key (l must have three fingers 93 arranged to actuate two upper slides and one lower slide to make a dash perforation and two dot-perforatious in the necessary sequence, and so on throughout the entire range or series of letters or ordinals.

In operation the space-key 53 may be depressed so as to slide the rod 01 forward and move the cross-head against the tension of the springs 65a, thus moving the group of punches 75 to 80, inclusive, through the dieblock and the die-plate to produce the feedholes 101 102 inthe ribbon, the parts being returned by the springs 05"L to normal position on releasing the finger-pressure. At the same time the collar 73 on the rod 01 is carried forward against the shank 70n of the cross-head 70, which is loosely fitted on the said spacing-rod 61 and is fast with the feedrod 27, and this described movement of said feed-rod carries the pawls 4:6 111 forwardly without advancing the ratchet, the latter beving held against idle play by the check-pawl 51. After the spacing-key has been released and the group of punches 75 to 80, inclusive, and the cross-head 05 shall have been returned to normal position, so that the punches are clear from engagement with the paper ribbon, the feed-rod 27 is forcibly returned to its normal position by the energy of the spring 35, and during such return movement the feedpawl 46 is active to turn the ratchet 2G a proper distance, thereby rotating the shaft 22 and the feed-wheel 24, the pins 25 of which feed-wheel engage the perforations 101 of the paper ribbon, so as to advance the latter a proper distance through the die-block, all the parts returning to the position shown by Figs. 6, 10, 11, and l2. When any one of the character-keys throughout the series is depressed, the proper rock-shaft is actuated and its fingers 93 press against the studs of the upper and lower group of slides, (one or more of each group,) and the slides thus brought into service are pressed forward simultaneously, so as to advance their character-punches for making the dot-and-dash perforations in the paper ribbon in proper order or sequence, as in the telegraphic code, for which sequential order the staggered arrangement of the punches is an important feature in securing the desired operation. As is evident, the forward thrusting of the punch-slides makes them push through the holes in the die-block and the plate, so as to perforate the ribbon, as described, and although the slide 01 is not actuated by the space-key it is moved by another train of connections, because the cross-head G5 is pressed forward by the shoulder or shoulders 66a or 67 on the characterpunch slides now in service at this particular period, whereby the group of feed-punches 75 to 80 are advanced simultaneously with one or more of the character-punch slides and at the same time the collar 73 is made to press against the cross-head 70, which correspondingly advances the feed-rod 27 and moves the pawls l1 4G to the positions shown by Fig. 13.

, wheel 24, so as t'o feed the paper ribbon through the die-block, and thereby present a fresh surface to the action of the punches on the depression of the next key.

In Fig. 13 of the drawings I have represented in full lines the action of the letterkey b, by depression of which' the rock-shaft 59 makes four of the fingers 93 act against the studs on the slides f b c d of the two groups of slides for the purpose of advancing the punches S6, 82, 83, and 84 in the sequence described, so as to make one dash-perforation below the line and three dotperforations above the line, and at the same time the entire group of feed-punches 75 to 8O is advanced for the purpose of punching the series of feed-holes in the paper ribbon.

Of course the spacing-key may be actuated to separate words or sentences, and it actuates the feed-hole punches independently of the character-punches and also actuates the feed mechanism to advance the paper ribbon.

Changes within the scope of the appended claims may be made in the form and proportion of some of the parts, while their essential features are retained and the spirit of the invent-ion is embodied. Hence I do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.

Although I have shown and described the machine as having a particular number of keys and feed-punches, I reserve the right to increase the number of characters and feedpunches whenever it is necessary to punch other characters. I also reserve the right to provide means whereby the speed of the feed mechanism may be increased while the stroke of the punch devices may be one-third or even less and still operate to turn the feed- Wheel the proper distance. lt is evident that the spring 35 may be placed at the opposite erd of the machine or in front ofthe machine and along the othersprings or that any equivalent arrangement may be adopted. i
