This invention relates generally to a new and improved type of record form employed in combined printing and punching telegraph recorders, and to the method of and means for preparing the record form. v

In certain types of telegraph systems a record form is used in `which the telegraph signalsr are recorded both as printed characters'and yas coded punchings Yon and in the form respectively. These formsare prepared by recording mecha-173:0 nisms which are capable of simultaneously printing and punching a record form under-the control of a common selector mechanism responding to the telegraph signals. Examples ofl'telegraph instruments of this generalY character are dis-l5 closed in Patent No. 2,174,731 granted-October', 1939, to R. F. Dirkes et al. and entitled Combined telegraph printer and perforator, andiin Patent No. 2,143,828y granted January 10, 1939,

to R. F. Dirkes et al. andentitled Telegraphilo- A 'separated. Where the'printed characters and printer-reperforator. Both of these instruments employ type-Wheel printing apparatus in which the type are arranged in a single row. These instruments are-designed in such a manner' that the printed characters andthe codedff 25 punchings corresponding thereto are in registry in the same transverse -sections ',ofthe record form. However, there are other types of printerreperforators which, for structural or 'other reasons, are arranged so that the printed characters and the punchings corresponding there-v to may not be recorded in the record form in the same transverse'sections. Certain forms of type bar printing mechanisms equipped with punching facilities are not adapted to eilect bothls recordings of the telegraph signals in the same transverse section of the record form. Also, an instrument of the general character of either of the machines disclosed in the aforementioned patents, when equipped with a multiple row type '40 wheel which is shiftable axially in order to print from any of the rows of type, requires a slight modification to permit the use of a multiple row type-wheel, thereby necessitating-that the'punching mechanism be displaced longitudinally of the 45 record form. The result of such a modication is that the coded punchings and the printed characters corresponding thereto are not in registry in the same transverse section of the record form.

The displacement of the two records made in the record form makes it relatively difficult to associate any particular set of punchings with 'thecorresponding printed characters. `In the operation of some systems employing this type of 55 `an urgent communication record form it is frequently necessaryto separate `to record all of the communication'sat a central point originating at a branch station, which communications may be destined -for any one of a large number of `distant stations.` There may vloe attimes a yconsiderable accumulationof prepared tape awaiting transmission and including interspersed with others of aroutine nature. To expedite the ktransmission of the urgent communication that portion of the tape ,in which it is recorded is separated from the rest of 4the tape and inserted VVin a separate transmitter having a direct connection to the station of destination. It therefore becomes necessary to determine quickly lupon inspection the portion of the tape whichis to be the punchings corresponding thereto aredisplaced longitudinally of the tape, it is diicult for any-but ak highly skilled attendant yto determine ata glance the exact point at which the tape is to be severed. Also, where -a tape `prepared in this manner is to be inserted in a transmitter, diiculty arises in determining just which row of coded punchings are to be inserte over the transmitter feeler pins.

Accordingly, it is a major object of lthe instant invention to provide a record form having Vnon-registering printed characters 'and coded punchings corresponding thereto and also markings serving to link `the printed characters and the corresponding punchings.

Another object of the invention is to provide a method of and means for preparing a combination printed and punched record form in which the' printed characters and the f coded pun'chings corresponding theretoy are displaced longitudinally of the form and in which the visual association of corresponding printed and punched characters is facilitated.

Still another object of the invention is the provision ofa mechanism for simultaneously' printing, punching and marking a tape whereby difculties of tape inspection occasioned by nonregistry of the printed characters'and the coded punchings corresponding thereto are obviated to a large extent by the markings.

A further object of the invention is to provide means for preparing a tape with non-registering printedv characters and coded perforations corresponding thereto and also with oblique markings linking the printed characters and the corresponding perforations. The invention is disclosed herein as applied to the type of telegraph printer-reperforator disclosed in detail in Patent No. 2,143,828 to which reference has been made. The recording mechanism comprising a typewheel and a set of punch pins is selectively operated in response to tele-` graph signals to. substantially simultaneously print and punch the tape in accordance with a single selection operation. l'I'he recording mech-7A A anism, by reason of structural limitations, is arl-f l ranged so that the punchingand printing' op erations occur at different transverse sections of the tape. The apparatusis alsosupplied with a marking device by meansfjwhich obliqueparallel lines are printed uponv the tapey so that each line passes through aprinted character' and punching lever 24, the right hand end of which carries a cam follower which is secured to the lever by means of a pin or screw 26 and is adapted to engage the*l punching cam 2l. The left hand end of the punching lever 24 is substanrtiallyhorizontal and has attached to the upper side thereof by a plurality of screws such Vas 21 a substantially H-shaped block 28. This block is provided'with ve longitudinalslots in each of which there lis a punch pin interponent bar 29 which ris adapted to slide back and forth therein.vv The right hand ends of the interponent bars 29 and bifurcated for the purpose of receiving individualinterponent actuating 1evers'suchas'3l.` These actuating levers are operable -to'move either tothe right or to the left k as shownin thedrawing under the control of the intersects one edge of the tape at a point regis- Q tering with the transverse section ofI the tape4 in which the coded punchings corresponding to theprintedcharacter'appear.

For a complete disclosure of the apparatus of which theinstant invention is an improvement, refer" ence is made herein to the aforementionedpatent to Dirkes et al. No. 2,143,828. Having reference -rst to Fig. 1 of the accompanying drawing, the main frame casting of the combinedprinter-` reperforator is provided vwith a front section II which is attached to the mainframe by a plu-` ralityof screws such as I2.v An'offset bracket casting I3 is shown attached Vto thefront side of the section II. The main frame casting is also provided with a section I4 to which is attached a punch and fedmechanism mounting plate I6. The printing and punching operations are performed by mechanisms actuated by a, series of pivoted levers controlled in amanner to be de-V scribed by a pluralityof rotating cams.A A cam operating shaft I1 whichis adapted to be rotated once for every operation ofthe selector mechanism is suitably journaledyin `bushings (not shown)k attached respectively tothe bracket, I3 and4 to the section I4 ofthe main casting. Securely attached rto one portionofwthe shaft `selectorgmechanism which is responsive to `the telegraph signals.`

Attached to the front side of the punchand feed mechanism mounting plate- I6 is a -punch "block 32 which has attached to the top thereof ,two plates 33 and 34. A smallrecesfsislformed l betweenthetwo plates 33 and andservestto guide the tape 36 over a. row'of five punch pins such as 31 and also beneath a typewheel 38. The lower plate 33 isprovided withlve ,holes such as 39 arrangedxin alignment transversely ofthe tape 36 andserve to guide, the five punch'r pins 31. A similar row of` holes 4Iis, varranged in ythe upperplate 34', each in alignment with a vcorresponding hole v,39, inl the lower, plate 33.

' The holes 4 I serve as dies ycooperating withvthe 'punch pins tof form perforations in the tape, as

the punch pinsy are forced upward in a manner to be Adescribed,` The lower `ends of the :punch f pins such as 31 are guided by meansy of a series of holes formedin a plate 42 whichfis attached by means cfa plurality of, scr'ews `fsuch as 43 to the undersidejof the vpunch b1ockil2. y Each of the punch pins'is provided withashoulder suchas 44, the ,bottomY faces of which-normally rest upon the upperfsurface of theplate 472.- Resting upon the upper faces of the shoulders on the punch pins is a plate 45 which in cooperation with compression'V springs which may be individual to each ofthe punch pins such as 45 causes the. punch pins which are forced upward to be returned to their normal positions in a-manner to bedescribed. The punching apparatus is provided with` an additional punch pin 41, the purpose of which is to form feed holes in ,the tape-. The feed hole4 punch pin -41 is guided adjacent its lower end by a hole inthe platet-42 and atits upper end by a hole in, aplate 48,; A hole v in a A plate 49 Vlocated abovethe plate 43 serves asa I1 is a group of three disc cams I8,` I9 and 2|,

which are spaced from one anotherv along the axis of rotationof the shaft by means of suit; able spacers. vThese three disccams I8, I9 and 2 I.

, are hereinafter referred to as the tape feed cam,-

die for .theupper end of the feed holepunch pin 41.` A suitablerecessformed between the plates 48 and, 49 serves toguide the 'tape 4over ,thev feed hole punch'pin.` This punchpin is'also provided with a compression spring 5Il whichtends to'hold the feed hole punch-pin-41-in its normal Y lower position. i 'v f vA tape feedshaft meansinot shown)` attachedto-the top of the Vpunch block32. ,'The shaft 5 2 serves\to support a drum V53 which is approximately lequal, in

length to the width of the-taple -36 and `which is Yequal to the ,distance betweenl the feed holes front section of 'theV bracket I3 and at itsrear end in a boss 23 which forms part of thelbracket \,I'3. :The rod 22, serves to piVjotally supporta-75' formed in the tape by the feed hole-punchpin 41 and are adapted` to advancev the tapefthrough the punch block ,uponrotati on of the cylinder 152 is 'suitably 'supportedby 53. A rod 55 is supported between the legs of an inverted U-shaped member 56 and serves to pivotally mount aguide member I which cooperates With a spring 58 coiled about the rod Amounted on the left hand end of a feed lever 63 and cooperates with the ratchet wheel 59 to rotate the shaft 52 and thereby advance the tape. The star wheel 6| cooperates withv a detent roller 64 which is supported at the right hand end of a` pivoted lever 65 to hold the shaft 52 in its rotated position in a manner and for a purpose Well known in they art. The lever 65 is pivoted at its left hand end on an eccentric vshoulder screw 66 which extends from the mouting plate' I6 and has attached thereto a spring 6I which normally urges the detent roller 64 into engagement with the star wheel 6I. The feed wheel operating lever 63 is pivoted between its extremities upon the rod 22 (Fig. l) and carries at its right hand extremity a cam follower 68 which is adapted to engage the tape feed cam I8.

A printing lever 69 is pivotally mounted on a stud I| extending from the punch block 32 and carries at its right hand end a cam follower 'I2 which is adapted to engage the surface of the printing cam I9. Adjacent the left hand end of the printing lever is an upstanding section 'I9 which extends through suitably aligned holes in the punch block 32 and the plate 33 to a point adjacent one edge of the tape 36 directly below the typewheel 38.

A guide bracket T4 is attached to and extends upwardly from the bracket I3 and is provided adjacent its upper extremity with a slot I5 in which the printing lever 69 is adapted to operate, the slot serving as a guide for this lever. An angular bracket '16, also provided with a suitable slot to accommodate the printing lever 69, is attached to the bracket I4 and serves to supporil a pair of spaced bearing plates II. These bearing plates serve to journal a plurality of Vrollers 18, I9 and 8| arranged vertically with respect to one another. Spanning the bearing plates AII are guide plates 82 and 83 which serve to guide the tape 36 between the rollers I8 and 'I9,- The roller I3 serves as a platen for the 55 to hold the tape in engagement with the pins printing roller I9, The roller 8| is an inking f roller which is rotated frictionally by the printing roller I9 to supply ink to the latter roller.

'Ihe printing roller I9 is shown in detail in Fig. 3. Formed on the surface of the printing roller is a series of spaced ribs 84 which travel spirally around the roller. The distance measured normal to the axis of rotation of the printing roller I9 between the ribs 84 is equal to the distance between feed holes of the tape. The purpose of the printing roller I9 is to mark the tape with a series of spaced oblique lines in a manner and for a purpose to be described hereinafter.

Pivotally mounted at 85 upon one of the bearing plates II is a lever 86 which carries at its free end a roller 81. A spring 88 attached at one end to the lever 86 and at the other end to an extension 89 of one of the bearing plates Il serves to urge the lever 86 upward into engagement with a stop 9| which is attached to or formed in the extension 89. The tape 36, as it issues from between the guide plates 82, is led over `the roller 81 and into'the recess provided between the plates 48 `and 49'and thence through the feeding, punching and printing mechanism, as described. i f

In describing the sequence of operations 'of the apparatus embodying thevinvention, assume that the selector mechanism has been operated yinresponse to a telegraph signal.' The interponent actuating levers such as 3| are operated under the control of the selector mechanism to position' the punch pin interponent bars such as 29 either to the left or right. The interponent bars which are moved to the right are then in such positions that the vertical projections such as 92 formed in their left hand ends are located beneath their associated punch pins ,such as 31. The type wheel y38, also in response to the selector mechanism, is rotated to a position bringing the type element of the selected character directly over the vertical section 13 of the printing lever 69. With the recording mechanisms selectively operated as described, the

cam shaft I'I is rotated through one revolution' in the' direction of the arrow. The raised portion of the tape fedeing cam |B is first brought into engagement withV the cam follower'68; thereby pivoting the tape feeding lever63 in a clockwise'manner to actuatethe ratchet dog 62 as described to advance the tape 36 a distance of one character. The `disengagement of the cam follower 68 from the raised portion of the tape feeding cam I8 permits the restoration of vthe tapel feeding lever 63 by means of a retractile spring 93, one end of' which is attachedto the tape feeding lever and the other end of which is attached to a suitable ilxed portion of the Vframe structure such as a part of the bracket 14. The ratchet dog 62 is carried upward and is brought into engagement with another tooth of the ratchet 59 by means of aretractile spring 94.

Continued rotation of the cam shaft |I effects the engagement of the raised portion of the punching cam 2| with the cam follower 25. The

punching lever 24 is thus rotated about the rod 22 in a-clcckwise manner, raising the set of punch pin interponent bars sufficiently to cause the vertical projections such'as 92, which have been moved to points under their rassociated punch pins, to drive these punch pins upward through the tape 35, thereby recording inthe tape coded punchings corresponding to the selected character. The disengagement of the cam follower 25 from the raised portion of the punching cam 2| permits the restoration of the'punching lever 24 and the mechanism controlled thereby to normal under the control of a retractile spring 95. The compression springs such as 46 with which some or all of the punch pins 4I are provided act upon the plate 45 to move it downward. 'Ihe downward movement of this plate effects the withdrawal of those punch pins which had been elevated to perforate the tape.

Following the tape punching operation the cam follower I2 becomes engaged with the depressed portion of the printing cam I9, thereby allowing the printing lever 69 to be pivoted clockwise about the stud Il by a spring 96. Such movement of the printing lever raises the vertical section I3 to press the tape 36 against the selected type element of the type wheel 38 inorder to take the desired imprint therefrom. Thereafterv the raised portion of the printing cam I9 enanism is accomplished in ,of time.It is generally-rdiicult, and ininost thetape from the For example, the feed ing `this levers against theactionof thexspring 96 in acounterclockwisemanner. yi Y :Eachmovement of ythe tape 36 zthrough'the recording apparatus by the tape feeding mecha relativelyV short space cases undesirable, .to draw. source .ofsupply in suchfa short; time. Accordingly, the tape which is fed to the recording apparatus is first drawn from theloop formedl between the guide" plates k48-49 and 82thereby Vpivoting the arm 86 counterclockwise against the action roi? the spring 8 8. V Immediately following this operation, the spring 88 is effectiveto pivot the arm V86 relatively slowlybackntoits normal position, thereby drawing tape from the sour-ce of supply, such as a tape reel,` between thewrollers 18 and Y19. This movement of the tape between these rollers causes rotation thereof which results` in the marking' upon-thev tape of a Aseries of spaced oblique linesyby.` the roller 19.- Obvisuch as 98 priorto its passage to the recording mechanism.' Consider the recording of the letter The printed character is recorded in the transverse section o`f the tape 99 and the coded punched recording isV made in the transverse section of the vtape I 0I. These two recordings are separated 'from each other by otherprinted and punched recordings for the reasons hereinbefore discussed. One of the oblique lines |02 passes through the printedcharacter "H in the transverse section 99 and intersects the opposite edge of the tape in the transverse section IOI. The

`.coded punchings recorded in the transverse section 99, instead of corresponding to the printed-- character H also appearing in 'this section, correspond tothe printed character Tappearing in the transverse section I03,.which two recordings are associated by theoblique-line |04 linking these two transverse sections. Thus it is apparent that, where structural limitations of the recordingapparatus necessitate 'the displacement of the printed and punchedrecordings of charactersv longitudinally of the rec- Vsaid record form, and oblique lines ord form, the visual association of the correspondis` materially facilitated by Vthe upon the record form. Hence, when it is desired to insert a tape `prepared in this manner in a transmitter, it is only necessary to scan quickly along the line running ing recordings'Y oblique lines marked through fthe printed character at the beginning of ja message `to the point where thatline intersects the opposite edge of the tape. This point may then be readily aligned with the transmitter Vfeeler pins or with some `distinctive mark or indexwith whichthe transmitter may be pro'- yvided to indicate the position of thefeeler pins.

A recordv forml prepared in the manner described does not require the services of an attendant skilled inreading the coded punchings appear- .ing rtherein nor does it require time-consuming counting of the number of recorded `characters between any printed character ,and its corresponding coded punching.

The nature Vof the Ainvention may be ascertained from the foregoing description of a method of and means for preparing the novel record form and the scope thereof is defined in the appended claims. n
