3,029,924) EMBGSSING 'MA'CHENE v Lyle W. Seifried Mentor, Ohio, assignor-to fiddressograph-Multigraph-Corporation, Cleveland, Ohio, acorporation of Delaware Filed June27,;1-960, Ser. No: 38,801 llvClaims. (Cl. 197-65) This invention relates to embossing machines of' the kind used to" produce embossures on relatively small plates that areto be used for imprinting'purposes'.
Repetitive printing'of'fixedand determinedidatais' advantageously; etiected, and accurate and permanent recordkeeping' greatly facilitated-by having reso'rt'to relatively small printing, plates bearingthe' fixed da'tain the form of embossed type characters. Such" plates can be fed quite rapidly through printing machines of the kind which automatically produce corresponding imprints on record sheets, envelopes and the like; Printingplates o-f lthis nature can also be used inhand operated printing'machines that are primarily used in connection with department store and oil service station credit transactions. In most instances, each plate bears a name and address which is to be imprinted. Additionally, each plate will usually bear' accounting dataisuch as a policy o'r'social security number, customer designation and'soon to be imprinted. Printing plates of this kind can also be used for tax accounting, inventory control, routing of parts in assembly factories and soon.
In order to facilitate the sorting and collation of business forms and the like, it has been proposed 'thatsuch repetitive-printingtransactions be assigned codes and that such codes be related to stylized numerical characters that are easily'scanned by photoelectric cells or other responsive scanning matrices.
Thus, accurate-scanning is assured by stylizing the numerical characters to obviate the possibility of one numeral being confused with another in the scanning apparatus. At the" same'time, each numeral is assigned a code'based on a five bit code'aswill hereinafter be described, and this code; can beimprinted on the 'busin'ess'fo-rm by magnetic ink so that'the imprinted code can besensed or scanned by magnetically responsive devices.
Pr'inting, plates hearing such stylized numerals and code representations are produced," under the' present inven tion; in an embossing machine. These data are to appear at certain assigned line' positions on'the resultant'embossed-printing plates apart from where are to appear alphabeticaldata'and standard numeralsthat are merely to be'used for-imprinting intelligent data requiring no scanning. Accordingly; the primary object of the present invention is-to'so construct an embossing machine as to enable stylized-numerical characters and code representationsthereof to be embossed on a plate that is to be used as a'printing plate in accordance with what has been described above, and to so construct the embossing ma- .chine as -to assurethat when-stylized numera-lsand code representations thereof are beingembossed, the chance of error is reduced.
Another object ofthepresent invention is'to so constructanembossin'g machine as'to assure that when the plate'being'embossed'is in a line location other than Where the stylized'numericalcharacters and code representations are to appear, the punch and die sets allocated to these data willbe prevented from effective operation. Another objectof the present invention'is'to enable the foregoing objects tobe achieved as acombinatio'n in an embbssingmachine that requires relatively few operative partsto effect'the cornbinedresults, and to do'this in an eflicient and inexpensive manner.
Specifically, anobject of'the present invention is to effect embossures byhaving resort toane'rrrbossiiig machine of the kind which'includes a'rotatable'purrch and die head under control of a shift mechanism adaptedto index or shift the head'frorn one punch-anddi'eposition to the next, just prior to effecting the "selected' embossure. The stylized'numeral andcode punch anddie slugs as a group. are assignedto one of'theshift or non-shift positions in the head, and certain of" the remaining alphabettype punch and die elements a're'assigned to the other positions. Each stylized number and the. asso'ci'atedcod'e are so'related as to be embossed simultaneously For reasons to be'explained hereinafter, the shift mechanism is to be in'an inoperative state when'the'carriage, which holds the plate being embossed, is ina' certain'lineposition', and the shift mechanism is then to be placed in'a'n operative state when'the carriage 'is 'in'anotherlineposition. In other Words, the position ofthe'carriage; from a line basis, is to control the operative 'orinoperative'state of the shift mechanism. Specifically, this is' accomplished by holding continuously inefiective thelock' fortheshift mechanism whenthe carriage is in a firstiposition, and conditioning this lock for eifectiveoperation when the carriage is ina secon'd'position; Additionally; when the carriage presents the plate for theembossing of normal alphabet and numeral characters, the punches and dies assigned'to the embossing'of'stylizednumerals and'associated code representations are tobe rendered in'efiective. These specific'features represent specific o'bjects'of the present invention.
Other and further objects of the'presentinv'ention' will be apparent from the following" description and"claims and are illustrated'in the accompanying drawings which, by way of illustration, show a'preferred embodiment of the present'invention and the principles thereof 'and what is now considered to bathe: best mode'contemplatedffor applying these principles. Other'e'mbo'diments of the invention embodying'the same or"equivalentprinciples may be usedand structural changes may 'bemadeas' desired by those slc'illedinlthe art'without departing from the present invention and the purview of the appended claims.

In FIG; 1 of the drawings there are illustrated 'anenlbossing machine 20 that is-adapted toemboss'a plateas,
P, FIG." 2, of plastic" or other easily"deforrnablem'aterial so as'to form raised, direct reading typ'e characters thereon inclusive of ordinary alphabetical characters AC and numerals ON delineating a name, address or the like, and additionally stylized, easily scannable, oversized numerical type characters NC and code representations CR thereof. The stylized numerals and codes are to be in the first line position on the plate, and the alphabet characters in any subsequent line position, but this obviously can be varied.
A plate as P can be of a size to be conveniently carried in a wallet, and the plate P is particularly adapted to be used in imprinting apparatus such as hand-operated printing machines and the like to imprint forms not only with a name, address or like alphabetical data, but also with stylized or specially configured numerical data and the associated code representations thereof derived respectively from the embossures NC and CR. The numbers NC and the code representations CR are configured and designed to be easily sensed or read as by photoelectric or magnetic-responsive equipment. Thus, code representations as CR for imprinting are primarily of advantage in connection with automated accounting systems wherein duplicate charge slips, tabulating cards or the like imprinted therewith are sensed, sorted and collated in accordance with the code data thus imprinted thereon.
As shown in FIG. 2, each Arabic numeral NC has one or more code bars assigned thereto, and these code bars are in accurately oriented positions shown by parenthetical numbers. There are five possible positions for the code bars, and hence the code is a five-bit code. The numeral 1 has two code bars in positions (1) and numeral 2 has two code positions respectively in positions ('1) and (4); numeral 3 has two code bars in positions (4) and (5) in effect representing a single long bar; and so on, but each numeral does require two bits or bars for representation, a binary code in other words.
Under the present invention, the embossures AC, NC and CR identified in FIG. 2 are capable of being embossed in a machine as 20, which is to say that the present invention makes it possible not only to emboss a plate as P with ordinary alphabet and number characters AC and ON but also with stylized, scannable numbers and associated code representations of the numbers. Inasmuch as each stylized number NC is to be accompanied by a code representation CR, each such number and the code representation thereof under the form of the invention here disclosed are embossed simultaneously in a particular line position of the plate undergoing embossing as will be explained. Such can be in any selected line position of course, but for purposes of explanation hereinafter it will be assumed that this will be the first embossing line position of the carriage which supports the plate being embossed. Consequently, normal alphabetical and number data such as a name, street address or the like will appear in remaining line positions on the plate P, and in this connection it should be pointed out that ordinary sized and configured numbers ON can be provided in the areas where the alphabet data are to appear.
Referring momentarily to FIG. 11, it will be noted that the first line position where the stylized numerical type characters and the code bars are to appear on a plate as P represents a relatively wide area on the plate whereas the alphabetical type occupy a much smaller line area. It will be appreciated that FIGS. 2 and 1-1 are merely exemplary of relationships, which is to say that the number of lines of embossed alphabetical characters will depend upon the intended purpose of the plate as P. In other words, while a name only has been illustrated in FIGS. 2 and 11, other lines may be allocated to additional data such as a house number and street identification.
The blank plates that are to be embossed in the machine 20 are stored in a supply magazine SM, FIG. 1, and these blank plates are advanced to an embossing station ES where the plate is positioned in the jaws of a carriage incidental to having the embossed data formed thereon in a manner to be explained in detail hereinafter.
Inasmuch as the plates P may be of a white plastic, it is advantageous under some circumstances to face the raised surfaces of the type characters with a distinct color. This can be accomplished after embossing has been completed by advancing each embossed plate to a tipping station TP, FIG. 1, where a film bearing olfsettable pigment material is pressed by a heated platen against the upper faces of the embossed type characters to cause distinctive coloring material to be offset thereto. This completes the formation of a plate as P, and each plate thus completed is advanced into a collecting tray TR at a collecting station CS.
Operation of the machine 20 is automatically controlled by a punched tape T, FIG. 1, which bears punched hole data instructions for automatic plate feed and positioning; plate loading and release; character and line space movement of the carriage, and so on in accordance with the disclosure in United States Patent No. 2,533,366. Thus, the tape T is read at a reader unit RU, FIG. 1, and bears all the instructions needed for fully automatic operation including the feed of the tape itself and the operation of key bars as will be hereinafter mentioned. Inasmuch as such automatic operations are fully disclosed in the above-identified patent, and constitute no part of the present invention, such disclosure need not be repeated herein.
Thus, the present invention is primarily concerned with the construction of an embossing machine enabling stylized numerical type characters and associated code representations thereof to be embossed, and in particular under circumstances where assurance is bad that an alphabet character will not be inadvertently embossed during the embossing of the stylized numerical type characters and their code representations, and conversely. This assures that the codes will appear on the embossed plate only where they should, and assures that the alphabet characters and ordinary numbers ON appear on the embossed plate only where they should. As a consequence, accurate imprints and accurate scanning are assured. The embossing machine 20 includes atop hood 25, FIG. 1, in which is housed a rotatable punch and die head member 26, FIGS. 6, 8 and 9, including a lower circular punch section 27 and an upper circular die section 28. These are rotated in a manner to be described hereinafter, and located about the periphery thereof are related punch and die sets which include ordinary alphabet and number punches 27A, FIG. 8, and related dies 28A. The alphabet punch and die sets are relatively small in size in comparison to the stylized numerical and code punch and die slugs to be described hereinafter, and are arranged in relatively narrow slots as 288, FIG. 6, arranged about the periphery of the member 26. Each punch and die element as 27A and 28A is movable to an actuated position in the related slot as 288 to effect an embossure, but is normally maintained in a retracted idle or inelfective position by spring-biased plungers 30, FIG. 8. Such embossing movement occurs only when the punch and die shuttle mechanisms as 31, FIG. 1, are interposed as will be mentioned hereinafter.
The punches and dies that are used to emboss simultaneously the numerical characters and their code bar representations are identified at 27B and 288 in FIG. 8, and a typical form is shown in detail in FIGS. 3A and 3B for the numeral 8. These punch and die slugs are quite large in comparison to those allocated to the alphabet characters as will be apparent from FIG. 8. Thus, the slugs 27B are not only configured to represent stylized, special form numerals as 8, FIGS. 3A and 3B, but also the two single form pips or bars that are to afford the code representations thereof. In order to maintain symmetry and balanced inertia, the numerical and code punch and die slugs are of the same size and hence must be sufficiently large not only to carry the large stylized numerals but also to afford sufficient space to account for the five possible locations of-.the single element code pips or bars CR and CR" as will be evident from FIGS. 2, 3A and 3B. Whether there is but a single pip (relief and intaglio in the punch and die) .or several, depending upon the code fort-he related numeral, each is elongated and centered on the center line of the stylized numeral as will be evident in FIGS. 3A and 3B.
In. view of the foregoing, thefpunch and diesections of the punch and die head. are provided with' relatively large slots 'asJZSS-I, FIG. 6, spaced substantially uniformly about thecircumference thereof, and slugs 27B and 28B are .retained in'position therein by spring-biased plun-gers 32, .FIG. 8, so as'to be normally held'retracted in. ineffective or' non-embossingposition. Embossing movement .is imparted to theslugs 27B. and 28B inthe samelmanner as above described in connection with the alphabet or ordinary slugs 27A and 28A.
During operation of the machine, the head member 26 is continuouslyrotating, and such motion emanates from a rotatable shaft '40. A collar 41 is pinned to the shaft 49, as will be evident in FIG. 7, and a vertically shiftable clutch sleeve 42, constituting part of the shift mechanism to be referred to hereinafter, is splined to' thecollar 41 so as to be rotated therewith; A"co1lar-45 is secured in a fixed position to the punch and die head 26, and this collar is provided with tooth projections 4ST which normally are disposed deeply in camming recesses 42R in the shift sleeve 42 to impart the drive to the rotatable punch and die head 26. In FIG. 8, however, the shift sleeve 42 is shown in its dropped or shift-producing position for reasons hereinafter to be explained, and such position is relatedto the actuated or energized state of a solenoid to be described.-
The foregoing construction of the punch and die head is disclosed in Patent No. 2,115,456, and as further explained in that patent, a ring of stops 50, FIG. 8 hereof, is arranged in a disc 50R well below the punch and die head 26. These stops are accurately oriented with respect tothe punch and die slugs 27A-28A and 27B-28B and are arranged to be actuated by selected key bars 51 such that when a particular key at the keyboard of the machine is actuated manually or as the result of punched tape control, the related key bar is lifted as viewed in FIG. 8 raising the associated stop 50 to dispose the stop St in the path of a stop arm 54 carried on a'lower extension 40E of shaft 40. Thus, the stops 50 are so related to the key bars 51 as to occupy positions in the ring SilR corresponding precisely to a punchand die slug that afford characters corresponding to the key that was actuated, and when a key-is operated, the-particular punch andd ie set will be located accurately at the'embossing station ES, FIG. 8, in position to effect a corresponding embossure.
Such embossing is eifected by imparting actuating forces to a'punch and die assembly that has been located at the embossing station, and such forces are established by respective punch plungers as 55 and di e'plungers as 56 that are actuated only when the shuttle mechanisms as'31, FIG. 1, are interposed between the 'plungers and the. plunger operating oranvil mechanism as described in aforesaid Patent No. 2,115,456.
After an embossure has been effected, the previously actuated punch and die set is restored back to ineffective position upon return or restoration of the plungers 55 and E56 by stripper fingers 57 and 58 thereon which have projecting hooks or lugs at 57L engageable with complemental projections as 60 formed not onlyon the stylized punch anddie slugs 27B2SB but also on the ordinary sized slugs as shown .in FIG. 8. Single projectionsas 60 are sufiicient to enable proper stripping'of the normal sized alphabet slug to be effected, but in view of the relatively large size of the punch and die code slugs, which are twice the width of the ordinary alphabet and number slugs, these are provided with additional projections' 61 RIG; 5, and in FIG. 4 is shown the dispositionand allocation of stopbars 59'. The space in the punch and die head is blanked at BX, FIG..6, .on'eithcr'side ofa' nus metal and code slug; which is to say that the positions BX are not occupied by punch or die elements. However, theslots 2884 are centered on the center line of'the equivalent of aslot 288, or in' otherwords each slot 283-1 occupies in effect the equivalent of two slots 28S. Noting that the stops 5.; are related to the centers of the slots 238, means areafforded under the present invention to assure th'atnone but stylized numeral and code embos-t sures will be embossed on the plate P when it is in a corresponding numeral and code embossable line positionat the embossing station ES, FIG. 8, and to assure that none butalphabet characters will be embossed when the plate is intan alphabet .ernbossable line position. This entails an explanation, first, of the operation of the shift sleeve and secondly a consideration of movement ofthercar riage FiGS; 11 and 12, which jaws 66 for gripping. and. presenting to the embossing station the plate P to be embossed Thefoperation of the parts illustrated in FIG. 8 is one wherein the punch .anddie head 26is rotatedby having theends of the prongs orteeth 4ST deeply seated in the slots 4251 to enable rotation of the punch and die head to be eifected. duringrotation of the shaft 40. The slots 42R are slanted such that by dropping the shift sleeve 42,
r the punch and die head will be shifted or indexed'one space center-to-center with respect to the slots 288. This effective shifting of the punch and die head is, under the present invention, allowed to occur only when the carriage isata line where the alphabetical characters and other normal characters such asa period, and sign) normal sized numerals, andso on are to be embossed separate and apart from the stylized numbers and their code representations. In other. words, the punch anddie slugs for the stylized numerals and code representations are restricted to the non-shift positionsin the head member 26, and in 'orderto prevent'rnissed or improperxembossuresan'dito. prevent damage to themachine. when stylized numbers and code representations are to be enr-' bossed, the shift mechanism to be further described here-v iii-after is disabled from effective operation when the can riageipresents the plate. in its first line position where such special embossures are to. appear.
On the other hand, when normal embossingis'to occur in a different predetermined line on the plate, the shift mechanism is to be rendered operable to permit the punch and die head to be indexed when required say from an upper case C to the. lower case counterpartor from upper case T to normal sized numeral 5 as will be evident from FIG. 5; The shiftsignals will be punched in the tapewhen the machine-is tape controlled. The shift positions are identified at SH in FIG. 5 and in-:' clude the BX or blanked positions. All others are nonshift positions. The stylized numeral positions in FIG. 5 (non-shift) are evident from the over-sized numbers shown in FIG. 5. In further explanation, it'will be noted that some of the stop bars 58 in FIG. 4 are allocated to the twopossibilities, namely, shift and non-shift. Thus; stop bar 56A is allocated to the ordinary numeral 4 as well as to alphabet character R; the numeral is a shift character, the letter is amen-shift character. So with C and c to which stop bar 5013 is allocated.
As shown in FIGS. 7 and 8, a shift yoke 70*.is provided, and this yoke includesa pair of arms 79A and 70B each having a shoe 71st the free end thereof disposed beneaththe enlarged head of theshift'sleeve 42. Thearmstof I the yoke are pivotally connected to the associated shift sleeve shoes. An arm 71' is affixed to the bight portion of the yoke 74), and this arm is secured to a boss 72, FIG. 7, which in turn is pinned to a horizontally extending shift rod 73. The shift rod 73 is in the nature of a rock shaft and is so arranged in the machine as to be clamped to one end of an operating arm 75, FIG. 9, which xtends at right angles to the shift rod 73. The arm 75 is pivotally linked at its opposite end to the upper end of a vertically extending solenoid-controlled actuating link 76. Link '76 at its opposite or lower end is connected to the armature 77 of a solenoid 80. This solenoid and a related solenoid 81, FIG. 9, are located below and at the right-hand side of the cover or hood 25 shown in FIG. 1.
The shift rod 73 tends to be biased clockwise as viewed in FIG. 9 (counter-clockwise as viewed in FIG. 8) by a relatively strong return spring 85 which is so tensioned on arm 75 as to apply a relatively strong upward holding force to arm 75, and it will be realized that the armature of solenoid 80 acts in opposition to the return spring when solenoid 8G is energized. Thus, the spring 85 tends to urge the shift yoke 70 upwardly to its normal position whercat the shift sleeve 4'2 is held upwardly with the teeth 4ST seated deeply in the recesses 42R, and this characterizes the normal or non-shift state of the punch and die head. This normal condition is to prevail during embossing of stylized numerals and associated code bars.
When the shift mechanism is conditioned to be in an operative state hereinafter described, arm 75 is to be locked in its down position to maintain any shift that may be originated. This is accomplished by a book 87 at the upper end of a bell crank 88, FIG. 9, which is pivoted at 89 on a pin supported by the bracket 90 which in turn supports the solenoids 80 and 81 in the machine. The righthand leg of the bell crank 88 as viewed in FIG. 9 is connected by a freely pivotal link 92 to the armature 93 of solenoid 31.
A pin 75?, FIG. 9, is atlixed to the inner face of arm 75 and in position to he latched or held by hook 87 on the bell crank 03. Thus, when solenoid 89 is unenergized, pin 75P is disposed above hook 87. The adjacent surface of the hook 87 is slanted or cammed to enable the pin 75? to move freely downward past the hook 87, causing bell crank 88 to shift, in the event that solenoid 80 is energized to cause arm 75 to be rocked counterclockwise as viewed in H6. 9. When the pin 75P passes under the hook 87, the bell crank 8t} snaps back into place in latching relation over the pin 75]? under the influence of its return spring 89, thereby latching arm '75 in the down position shown in FIG. 9. This of course is manifest in the shift sleeve 42 being allowed to drop substantially to the position shown in FIG. 8 causing the punch and die head 26 to be indexed through a shift space. If a shift is called for in an embossing cycle, the shift is effected just prior to the embossing operation.
On the other hand, if solenoid 31 is energized, then the bell crank 88 is shifted to its ineffective position shown by dotted lines in FIG. 9 whereat the hook 87 is out of the path of the pin 751. If solenoid 80 should be energized at the same time, and it should be noted that this is a momentary energizing condition in actual operation, pin 75F will in effect skip hook 87, whereafter the return spring 85 takes over thereby canceling out any shift of the punch and die head.
Under and in accordance with the present invention, the shift mechanism thus described is to be placed in an effective or operable state only when normal sized alphabet, numerical and related characters are being embossed, since it is at this time that it may be necessary to impart a conventional shift to the punch and die head as may be required by the punched hole data carried by the tape which controls the machine. Thus, if the data being embossed in the alphabet area of the plate P include characters such as a normal sized and shaped numeral 5, or a lower case c, which are shift characters, the control tape will be punched to designate energization of solenoid to produce the corresponding shift in the punch and die head, and under these circumstances solenoid S1 is to be allowed to remain deenergized so that latch 87 can perform its essential holding function to maintain and assure the shift position of the punch and die head. However, in order to prevent this condition from arising at the time when the stylized numerals and associated codes are being embossed solenoid 8-1 is placed under control of the carriage such that when the carriage is in position to present to the embossing station the line on the plate that is to be codenumeral embossed, solenoid 81 is held continuously energized thereby rendering the shift mechanism ineffective continuously so long as the carriage is in this position.
In view of the foregoing, and referring to FIG. 11, it will be noted that the carriage 65 is equipped with a conventional line spacing rack 90 having line spacing teeth 9ST meshed with a line space control pinion 92. This is a known arrangement in the art and is described in several patents assigned to the present assignee, and it should be noted that operation of the pinion 92, in automatic operation of the machine, is under control of electric circuitry that in turn is responsive to punched hole data in the tape T used for such automatic control over the machine. Under the present invention, however, shaft 93 which carries the pinion 92 is provided with a cam element 94 adapted to engage the switch finger 96 of a control switch 100. This switch 106 is a double pole switch. The relationship is such that when the pinion 92 has positioned the carriage rack 90 to present the first embossing line of the plate P to the embossing station to enable the stylized numerals and associated code pips to be simultaneously embossed, cam 94 presses the switch finger 96 to the position illustrated in FIG. 11, and this completes a circuit to solenoid 81 as will hereinafter be described. In this manner, the shift mechanism is rendered inoperable when the plate P is in such an embossing line position. It will be appreciated that any line position of the plate P can have this characteristic feature under and in accordance with the present invention.
Movement of the carriage 65 to the left as viewed in FIG. 11 characterizes movement of the plate being embossed from its first line or code-numeral embossing position to its second position where the normal sized and conventional characters are to be embossed thereon. This a relatively large movement as will be evident from the legends in FIG. 11 and is characterized by approximately an 80 turn of the pinion 92 and its shaft 93. This of course displaces the cam 94 from contact with switch finger which thereupon opens the poles that maintain the solenoid 81 energized. Consequently, solenoid 81 is returned to a d-e-energized state where the bell crank 88 will be effective as a lock to maintain any shift condition called for by the punched tape and manifest in energization of solenoid 89. At the same time, when switch finger 9:; moves to its dotted line position illustrated in FIG. 11, another set of poles of switch are thereupon closed to complete a circuit to a solenoid 105, FIG. 10, which disables those key bars 5d which might, because of an error in encoding the control tape T, be operated to select a punch and die having a stylized numeral and associated code. This should not be permitted to occur when the plate being embossed is in its second or normal alphabet and numeral position, not only because of character space requirements as will hereinafter be evident, but also because such would result in a false plate.
Thus, referring to FfG. 10, it will be noted that each key bar 51 is pivotally connected to a downwardly extending connecting link 106, and the lower end of the connecting link is formed with a slot 3.67 which extends inwardly from one edge of the link 106; A transmitting lever 11% is alforded to actuate each key bar link as 166, and one end of this lever is pivoted on a supporting shaft 112. The transmitting lever extends from the shaft 112 in the direction of the link i 36, and.a pin-1'15 at the free end of the transmitting lever is normally disposed at'the closed end of the slot 197.
As described in Patent No. 2,533,366prockers (12% hereof) are adapted to be rocked clockwise as-viewed in FIG. hereof in response to thedata carriediby the punched control tape, such rocking motionbeing induced by a code bar (not shown) positionedduring sensing of the punched hole d-atainthe-control tape; When so rocked, each.:rocker 120 presses ion the. toe'121T of a realted'ihookwlever 120which, it should be noted, is also pivotally-related to the shaftlIiZ. Each hook lever 120 carries a pin 122 which is'disposed in a slot123'in the transmitting lever 116, such that'in response to actuation of the rocker 121} the transmitting link 110 is pivoted clockwise as'viewed in FIG. 10, and therefore motion is transmitted by pin 115 to theiconnecting lever lllfi which in turn actuates the key bar '51stoinstituteselectionof the corresponding punch andidiez'set.
Under the present invention, those ofthettcn connectinglinks 166 (ll through'9) that-are associated with the key bars 51. which select the code and numeral punch and die slugs are interconnected by a bail bar 13tiwhich in turn'is connected to the armature 1310f the solenoid 165. This bail bar has vportions disposed in slots 132 that are common to the heads'lMH of the ten links .ltlfiithat are assigned to. the keyvbars 51' of the code and numeral punch. and die slugs. Therefore, when theiarmataure 131 is pulled to the right as viewed in- FIG. 10 upon energization' of solenoid 1%, the bail bar'ftiti) is effective'to rock: this group of ten connecting links 1%: simultaneously to present an upwardly opening slot 133 in the head 1061-1 of each such link to the pin 135 of the: associated transmitting ,lever 110; Therefore, it such transmitting lever 110- should be operated erroneously at a time when the plate P' is in its second line embossing position, the result will be idle motion manifest in the related pin 115 moving idly down in the slot 133, and consequently the key bar'51 for'such erroneous condition will not be actuated.
It will be recognized particularly from FIGS. 2 and 11 that thereis a great deal more space between the embossed and: coded numerals NC on the one hand, and the: conventional embossed data AC and ON on the other hand. Thus, there is to be a different degree of character'spacing between the large embossures when the plate being embossed is in its first line position in comparison tocharacter spacing between the smaller embossures when the plate is in its second line embossing position. Referring to FIG. 12; this is made possibleby having resort to'a pair of character spacing racks l itl l and 144L112 which control character spacing of the carriage 65. Eachrack is individually engageable by the usual escapement pawl 142that is eifective between successive embossures to permit the carriage to undergo character spacing movement in a. manner well known in the art. When the carriage 65 'is in what corresponds to the first lineembossing position of the plate P, the 'escapement pawl is disposed in association with the character spacingtrack Me r which'has widely spaced teeth correspondingto the relatively wide jumps required when indexing the carriage left to'rig'ht during theicourse of successive formations of the stylized numerals and associated code bars.
The racks 1494i and 1494 are controlled by a'springbiased plunger 145. A biasing coil spring 146 surrounds the :plunger 1 145 :and this assembly is disposed inra guide opening'147S formed in afixed'member 147 which affords part of the guide structure for the carriage65;
The arrangement for the spring is'su'chthzit the spr ing 146 applies a leftwardly'directe'd force, as viewed in-FlG.
12, against a washer and spacer 148 at the left hand end of the plunger 145. This force is resisted by the right hand leg of an inverted U-shaped bracket 150- which em braces the adjacent end of plunger 145. The opposite or left hand leg 1510f this bracket bears against'the head of a spring-biased plunger 152 having aconcentric'sp'ri'ng 153. PlungerlSZ'is supported by an arm 154 depending from and secured to the'underside of the carriage 65. Spring'153 in elfect loads or compresses spring 146i When the carriage 65"moves from its first to second position as above described, plunger 15Z is-moved'away from bracket 151 thus permitting spring 1'46 'to'take over, and plunger 145 is allowed'to shiftto the left as viewedin l2"until"rack -14i 1 bears against the solid surface immediately adjacentthereto. Asa-corn sequence ofthis, the character-spacing 'rack"14tl2, having'the closely spaced teeth, becomes associated with the character-spacing escapernent pawl 142;
The control circuit for solenoids 8t], 81- and ltl5 'is' shown in FIG. 13. 'With cam 94 in the first position of the carriage (stylized numeral and code embossing) indicated at 94 1 in FIG. 13, switch finger'96-is positioned to'close contactsEl-and E2; Solenoid-81 is connected by a wire E4 to a wire ESconnected to ground. Solenoid sl is connected to-contact E2 -bya wire E6; and the conducting element of switch arm 96 carries contact and is connected to a Wire E8 1 which in turn is connected'to wire Eli? in the'positive side of the circuit. Consequently, under this condition,'- solenoid 81' isheld de-energized to disable the shift latch, and no shift condition will bemaintained even though solenoid 84) should be energized.
The conductive element of switch arm 96- includesa contact E12 adapted to engage a relatedcontact E13 when cam 94 moves to its second, dotted line position 94-2 shown in FIG. 13. This occurs when shaft 93 turns during movement of carriage 65 to its second position; Contact E13 is connected by a wire E1510 one side of solenoid 195,- and the other side of solenoid 105 is connected by a wire E16 to wire E5. Therefore, in thesec- 0nd position of the carriage, solenoid 81 is de-energized to enable the shift latch to be effective, and solenoid 105 is energized to prevent any effective action of the punch and die elements 273-233. The shift solenoid may now be effective to produce a shift of the punch and the head. Thus,.solenoid as is-adapted to be energized pro vided switches E20 and E21 in its circuit'are closed'i Switch E'Zil is a cam-operated timing switch and switch B21 is a switch responsive to the sensing of punched hole data in the tape T calling for a shift character to be embossed.
In order to release the holding latch 87 aftera shift character has been embossed, solenoid 81 should be energized, and aseparate circuit for this'eifect is provided. Thus, wires E25 and E26 are connected to and shunted between wires E6 and E15, and a timing switch B38 is interposed therein so that solenoid 81. will beener gized late in a shift embossing cycle so as to release latch It will be appreciated that while the present machine has been described from the standpoint of automatic tape control operation, a manual operation can be effected as 1 well, in which event the key bars instead 'of being-tape controlled will be mechanically controlled and a shift key canbe provided to effect closure of switch E21."
It will be seen from the foregoing' that'the present in vention enables printing plates ofthe kind described to be embossed to hcar stjviized numerals and code representations thereof in addition to normal alphabet and nuimerical characters. Accidental 1 embossing ofstyli'zed numerals and code-representations is prevented by-disabling the associated key barswhen the carriage islocated to present the plate being embossed in the line position Whereat the normal or standardch'aracters are tobe embossed, and I at 'this' time the shift mechanismiiis :con'ditioned to be in an effective state. On the other hand, when the carriage is in a location Where the plate is to be embossed with stylized numerals and code representations thereof, the shift mechanism is rendered inoperable or ineffective, and this assures that the punch and die head will not be indexed through a shift movement at the time when stylized numerals and code representations are being embossed. Advantageously, each stylized numeral and related code representation is provided in relief and intaglio form on respective one-piece punch and die slugs, and the corresponding configura ions are centered with respect to one another and with respect to the particular slug involved.
Hence, while I have illustrated and described a preferred embodiment of my invention, it is to be understood that this is capable of variation and modification, and I therefore do not wish to be limited to the precise details set forth, but desire to avail myself of such changes and alterations as fall within the purview of the following claims.
