Serial No. 68,307.

The present invention relates to improvements in selectivel systems and apparatus therefor.

More particularly the invention relates to an improvement in methods of operating telegraph shift control mechanisms.

In printing telegraph machines for transmitting the stock market quotations letters are ordinarily printed in one'line While the figures are printed in another line. As a result, when the usual form of Vpermutation code printers is used for this class of transmission many more shift operations occur than in ordinary message transmission. Afterl each group of letters or figures a special shift 'or unshift combination must be transmitted and the speed of transmission is slowed up materially.V For this reason permutation codes have not heretofore displaced the step by step stock ticker systems. In emergency signalling, as for example Iin lire alarm andpolice telegraph systems Where the usual type of printing telegraph machines with the ordi-..

nary shift controls are utilized the Operator may fail to send the shift and unshift sig- -nals properly, with the result that at critical times the matter transmitted becomes unintelligible. v

In accordance with the presentinvention the number of shift Operations is reduced by adding to the character selecting limpulses of each signal a shift selecting impulse which Will operate only to determine IWhether a letter or a figure is to be printed. In Baudot o r permutation code printers, .a sixth selecting impulse is added to the five character selecting impulses of each signal transmitted. Mechanical and electrical means are provided to carry out "the invention vand iin the vpre-l ferred embodiments are so arranged that the printer shift mechanism will remain in either figures or letters position as long as figures or letters are transmitted successively, and Will change the position only when the transmission changes from figures to letters or from lettersto gures.

Accordingly, an object of the present invention is to provide' a novel method of signalling in which the special shift and unshift signals ordinarily transmitted in permutation code systems are eliminated and in which a shift or unshift signal is transmitted as part of each` character combination.

A further object of the invention is the provision of novel shift mechanisms for permutation code printing telegraph machines especially adapted for the rapid printing of matter such as stock quotations in which a great many shift operations occur,Without the transmission of special shiftv and unshift signals.

Still further objects of theinvention Will appear hereinafter in the` detailed disclosure of preferred embodiments of the invention the various combinations and subcombinations hereinafter set forth and as defined by the terms of the appended claims.

bodiment of the invention in which the mechanism is shifted only when required to eli'ect the printing of characters in the proper case.

As shown in Figures l1 to 3 inclusive, the subject matter of the present case is a continuation in part of the subject matter in copending application Serial No. 656,857,1iled August 11,v 1923, now Patent 1,567,599, granted Dec. 29, 1925, and only so much of the mechanism shown in the copendingapplication has been here disclosed as will be necessary for a complete understanding of the present invention. Accordingly reference characters appliedto like parts in the present case are the same as the characters applied to the same parts in the copending case, and the copending application may bereadily referred to for a full' understanding of the varions details of the selector and yprinting" mechanisms not herein fully set forth. The selector bars 59 to 63 and the shift control bar 501 shown in Figure 1 may be controlled mechanically by a single selector magnet as lset forth in the copending case, or may be cont-rolled by selector magnets indiviiual thereto from a rotary distributor in eith r a multiplex or a start stop lsignal printing telegraph system in any manner well known to the art. The type bar action comprising the. actuating bars 108 arms 113, type bars 116 and the action of the printing bail parts 125 to 129, the action of the spacing mechanism controlled by the-parts 166 to 169, and the' ribbon feeding actuating mechanisms, and the various other printin actions will be fully understood by a re erence to the copending case.

The mechanism related to the'present invention comprises platen block 488 mounted on a head 489 which is mounted slidably in a guide bracket secured to frame 400. An extension 491 of member 489 is pivotally linked s to a rocker arm 492 which 4is pivotally suplwill be printed and vthe ribbon will be properf 1y shifted by di ported from frame 400 'at 493. Ribbon shift pivot 318 is secured to and movable with an extension 494 of arm 492. A spring 595 kconnected to arm 492 tends to throw arm 492 with 488 and 489 forward into-shifted osition.

Block 488 is just wide enough to e positioned under one of the characters carried by type bars 116 as shown in Figure 1. Secured to head 489 are a, plurality of members 495, which, as the head is moved inthe shift operation are arranged to depress the edges of the tape in order to insurecontact with the tape of only the one character under which block 488 has been interposed. It will be seen that according to the position of arm 492 either an upper or lower case character e movement of extenslon 494. A pin 496, secured to 492, is in slidable engagement wlth a slot inthe end of a shift op- 'erating member 497 Member 497 is pivoted aligned slots.

"and there will bar 497 until the printing has been effected at a point 498v and urged to the right in Figure 1 by a spring 499, to maintain a cam projection 500 thereon, against bar 125 of the printer bail operating frame. A special shift control bar 501 is added to notched selector bars 59 to 68, andan eXtra cam, selector finger and latch, are added to the selector cam' shaft shown in the copending application to control this bar by a line impulse in the same manner as the selector bars 5 9 to 63 are controlled. The signal periods, when 'this bar is added in a start stop printing system will be made up of eight intervals, namely, a start interval, ive selector bar control intervals, a `shift control interval, and a stop interval. The transmitter will be arranged to transmit amarking condition in the shift control intervalwhen block 488 is to be shifted to print van upper case ligure, and to transmit a spacing condition when block 488 is to remain in the letter printing position. The selector cams will of course be spaced accordingly, in proper angular and axial position;

-A stop projection 502 is carriedv by bar 501 in such a position that it will be ldirectly beneath the end of shiftcontrol bar 497-when bar 501 is in unactuated position, and a wide slot is cut directly beneath bar 497 in all the notched selector bars so that bar 497 can move Ainto these wide slots with the selector bars either in actuated or unactuated position. When a marking impulse is received during the shift control interval, bar 501 will be permitted to move to the left in Figure 3 under the influence of its spring 65, and as the printing bail moves u ward, bar 497 will rock on its pivot 498 un er the influence of spring 499 witheam projection 500 in engagement with bar 125, and will move into the wide selector bar slots. The actuatin bar 108' selected by the arrangement onotched bars will also be Vmoved into its bar 497 will have moved to a position which will have caused arm 492 to be moved by spring 595 to shiftblock 488 into its forward or upper case position. The printing stroke of the selected t pe bar will then commence lie no further movement of and the selected type bar has returned to normal. 'Then the return or downward movement of the printer bail frame will cam the selected actuating bar 108 and bar 497 out of the aligned slots.' .As-soon as thebars 108 and 497 have been lifted clear of the notched selector bars, member 77 isactuated by cam 90 to restore the selector bars andthe shift control bar 501 to unactuated position, when stop projection 591 will again be positioned under barv497. Until another code combination,

with a marking impulse in the seventh intervals is received,bar 501 will be locked 1n the position shown in Figure 3 by its control thev AVhen the two bars -have reached-the bottoms of their respective slots,"

The platen construction and the carriage are` the same. as shown in the copendingapplication andthe tape together with the platen is shiftedbodily. A shift control-member 503 suitably pivoted on a point 504 to the frame (not shown) has the upper end thereof normally held against the projection 502 of the shift control bar 501. `A n actuating projection 506 formed on member 503 is urged into engagement with the printer operating bail member 125 by the springV 505. Pivotally secured to the lower end ofthe member 503 by means of pin 507 is a shift control latch member 508. Member 508 is provided with extension 509 normally held in engagement with an edge of the member 503 by means of helical spring 510 which'may be coiled around and supported on an extension of the pin 507 (notl shown). A carriage shift Vbell crank member511 is pivotally supported from the frame by means of a pin 512 and is normally urged counter clockwise by the spring 513, until a projection 514 thereof engages the end of the latch member 508. Pivotally secured to the end of one arm of the bell crank mem,

ber 511 by means of pin 515 is a link '516. Link 516 is provided with a. guide slot 517 adjacent the upper end thereof through which the guide pin 518 extends. Guide pin 518 is suitably secured in the supporting frameworkl and guides and limits member 516 in a reciprocating motion. The upper end of member 516 is adapted to be engaged by the\lower surface of the printer actuating bail member 128. Formed on the other arm of the ell crank member 511 are the extensions 519 e,

tween which a pin 520 is positioned. Pin 520 -is secured to the member 420 of the platen carriage. Securedto the member- 420 are the ribbon shifting elements 319 and 324 which shift the ribbo in position for printing when du shifted as will more fully appear by a reference to thecopending application. As set forth in the copending applica'- tion projection 415 of the member 420 is adapted to engage the stop screws 442 and 443 and will limit the travel of the carriage.

Supported from the'member420 isa carriage positioning roller or member 521 which is adapted to ride over the projection 522 of the 'l limiting member 523. `Member 523 is pivot-` ally mounted and urged preferably by a spring (not shown) into yielding engagement v with the roller or member 521.

In operation of this form of the invention the parts are normally positionedfas shown and the platen together with the tape (not shown) will be positioned to receive printing impressions of the selected type bars 1n lower case or unshifted position. As the printing bail structure moves to effect print-q ing strokes in a manner more fully set -forth in the copending application, the stop 514 will engage the end of latch member 508and motion of the bell crank member 511 under .inf.

luence of spring 513 will be prevented. When, however,;a character in the upper case is selected the shift control'bar 501 will be actuatedv and will shift the projection 502 v from beneath the end of the member 503. As the printing bail moves in its printing stroke,

spring` 505` will shift member 503 clockwise about its pivot 504 under control of the printing bail member 125, and the cam projection 506 and the end of latch 508 will be shifted to the left in Figure 5 until it is disengaged from the stop member 514. A s soon as this disengagement occurs spring513 will shift the bell-crank member counterclockwise and the right extension thereof will engage the pin 520 and will shift the member 420 together with the platen and tapeinto the upper oase or shifted position. The parts are so proportioned and arranged that .the movement of the platen into shifted position will be complet-ed before a printing impact of the selected type bar is effected. After the l printing of the selected character has been effected the printing bail structure will be returned, as more fully set 4forth in the copending case, andthe selected type'bar will return to uliactuated position. As theprinting bail -structure ret-urns normal and moves the member 128 downward the side' of member 128 will engage the end of link 5.16y and will force the bell crank 511 in a clockwise direction. At the sa'me time bar v125 will move the member 503 until the'end of latch 1- 508 drops behind the projection 514 and projection 502 of the bar 501 ismoved t'o the position shown in Figure 5. During the return movement of the printing bail structure,mem

ber 125 will engage the cam projection 506 of `member 503 and `will force the end of the member 503 out of the aligned selector bar slots. During this motion ofthe member 503 the end ofthe latch 508 will engage the left side or edge of the projection 514 and the latch 508 will move about pin v-507 as a pivot until the return movement of the printer bail permits spring 510 to vforce the latch 508 into position shownin Figure 5. When this occurs'the parts will be locked with the platen and tape inunshifted or lower case position.

In the forinshown in Figure 6, a,l further l modification of the invention is shown in which lthe carriage is. moved to the upper case -or 'shifted position by means of a cam member and isfrestored by means of a spring. In this..

form the shift actuating bar of the copendstroke.

-420 in engagement with the cam extension 433. When a selected character is to be printed in the lower case position the projection 502 of the bar 501 prevents motion of theV shift actuating bar 108 into the aligned slots and the platen'will remain in the position shown in Figure'G, as printing of the selected chai'- acter is effected. lVhen, however, the character is to be printed in the upper case or shifted-position, in addition to selection of the type bar carrying the character to be printed the bar 501 is selected and theshift control bar 108 will move into the aligned slots as the printing bail moves in its printing As the bail moves in .its printing stroke cani member 433 will be shifted vertically and will force the carriage together with the platen and tape into position toreceive the upper case or shifted character impression just before the printing impact of the selected tape bar. As the partsrestore to normal spring 435 will move the shift actuating bar downward and spring 524 will effect the return ofthe platen carriage to normal or unshifted position as shown in Figure 6. y

In'the forms of the invention so far describedthe shift mechanism automatically restores to normal position after each shift movement, and must be moved. from normal position each time a character is to be printed in the shifted position.' This introduces unnecessary movement in the mechanism when successive characters in the shifted position are to be transmitted. In the preferred embodiments of the invention hereinafter set forth, the shift mechanism will remain in a given case position until a different position is required for the printing of a succeeding character. I

In the form of invention shown in Figure 7 the shift arrangement shown in Figure 1 is modified for application to a multiple magnet printer, and is so arranged that the shift mechanism is actuated only when the ca se position is to be changed for the printing of the chai'acterbut the shift selecting condition is transmitted with each character as above set forth. This is accomplished by eliminating the actuating lever 497 for the platen shift arm 492, and eliminating the shift pulse control selector bar 501. The platen arrangement is the same as shown and describedin connection with Figure 1, and only the changed parts will be here described. Arm 492 is actuated by a link 526 connected thereto at one end against the tension of spring 527. The other end of the link 526 is pivotally connected to a plunger 528 of the solenoid529. One terminal of solenoid -529 is connected by conductor 534 to a terminal of the winding of locking relay 535, the other terminal of which is connected at 536 to the conductor 530 and to armature 537 of relay 535. Armature 537 is adapted to connect the conductor 530 and winding 535 to the positive pole of an electrical source of,

supply when relay 535 is energized. Conductor 534 is connected through normally closed contacts 539 and 540 to the negative pole of the electrical supply. Contacts 539 and 540 are controlled by the member 541 carried on an end of the lever 542 pivotally supported at 543 from the printer frame. The end 544 of lever 542 is positioned in a manner to be engaged at the end of a printing stroke by the printing bail 128. An inductive shunt resistance 546 is preferably connected across conductors 530 and 534 to make the relay 535 slow to release so that contacts 537 and `538`will remain closed until brush 532 returns to segment 1.

In operationof this form of the invention the code combinations of'selecting impulses in each channel are received in the usual manner, and distributed to the proper segments 2 to 6 of the distributor causing the setting o f the selector bars 59 to 63 in selective combinations. To eachcode combination of impulses, a shift control interval is added so that each signal is made up of the usual permutations of selecting conditions and. an

added sh'ift control condition. When a lower case character is to be printed, the shift'control pulse or condition is a spacing condition and printing will occur with the platen in the position shown in Figure 7. If an upper case character is to be printed, a marking contion of relay 535 completes a locking circuit4 through Contact 538 and tongue 537 for solenoid 529 insuring the holding of platen 488 in upper case position until after the printing impact of the selected character.

lao

After the printing impact is completed bail 128-will engage end .544 of lever 542 causing movement of'member 541 to separate contacts 539 and 540 interruptin the locking circuit through solenoid 529 an relay 535.

If the inductive resistance 546 is omitted,

the platen will then return to lower case po- .nism is such that the locking circuit through contacts 539 and 540 is broken near the end of the cycle so that a comparatively small prolongation of the energization of relay 535 will provide sufficient overlap to hold the mechanism in shifted position while a number o-f characters are printed in succession in the same case position and until a character is to be printed in lowercase or unshifted position of parts.

While the shift control pulse has been disclosed as thelirst pulse of the signal combinations and this arrangement is preferable because la maximum time is allowed for the shift operation before the printing impact, it will be understood that any other impulse of the signal combination may be utilized to control the shift mechanism. It will also be understood that arrangements shown in Figures 5 and 6 may be modified in like manner for magnet operation of vthe shift mecha'- nisms. The magnet shift control may also be applied to operate the shift mechanism of any ofI the well known permutation code printers which may thereby be adapted for use in a system embodying the present invention.

In the form of invention shown in Figures 8 and 9, a preferred embodiment is disclosed in which the .shift mechanism is mechanically actuated, and the platen remains in one position until a character is to be printed in a different case position. In this form of the invention the platen 488 and the platen block 489 are supported on and slidable on the member 490 as set forth in connection with Figure 1, and the tape feeding and supporting means in this form of the invention are the same as are shown in Figure 1 to which a reference may be had for a full understanding of the parts. Platen block 489 is formed integrally with or rigidly secured to the actuating extension 547 to which the ribbon shifting parts are connected at 318. The rear end of the actuating extension 547 is pivotally connected by means of pin 549 to one end of mits shifting of the parts un supporting link or member 550 which at its other end is pivoted at 551 to the frame 400 of the printer. Rotatably supported on the pin 549 at opposite sides of the extension 547 are shift and unshift rollers 552. The shift roller 552 in the Figure 8 engages an edge of the cam extension 553of shift actuating bar 554. The opposite edge of the cam extension 553 reacts against a roller 555 which is pivota-lly supported on an extension of the frame 400. Suitably supported from the frame 400 is an unshift reacting roller or member 556, against which one edge of the unshift cam extension 557 of the unshift actuating bar 558 is held by means of spring 559. Shift and unshift actuating bars 554 and 558 are provided with cam projections 110 and actuatingshoulders 111 such as are provided on actuating bars 108.' Shoulders 111 are adapted to be engaged by the printing bail 128, and cam projections 110 held in engagement with the bar 125 of the printing bail structure by means of the springs 560.

Shift control selector bar 501 is provided with a projection 561 which in the unactuated or unselected position of the bar 501 prevents movement of shift actuating bar 554 to the right in Figure 8 into the aligned slots 562 of the selector bars 59 to 63 and the actuated or selected position of bar 501 permits movement of actuating bar 554 into the aligned slots 562 during a printing stroke of the bail structure. Bar 501 is also provided with a projection 563 which in the selected or actuated position of the bar 501 is positioned beneath the unshift bar 558 and prevents moveselected position of the bar 501 the unshift bar 558 is permitted to move into the aligned slots 564 of the bars 59 to 63. In order to insure the proper positioning of the platen 488 in the shifted or unshifted position a bell crank member 565 j suitably supported from the frame 400 on a pivot 566 1s provided with a triangular projection 567 which is forced into engagement with one of the rollers 552 by means of a spring 568. Projection 567 is so proportioned with relation to the roller 552 that the platen will be yieldingly held in either case position by thev action of spring 568,'which is of suiicient strength to hold the parts properly in either case osit-ion but periler the influence of the cam members 553 and 557.

In operation of this form of invention when a character is to be printed in the unshifted or normal position, the selection is set up on the selector bars 59 to 63 as above set forth and shift control selector bar 501 will remain in unactuated position with the projection 561 positioned beneath the shift actuating bar 554. After the selection has been set up on the selector bars, the printing mech- 1er y anism is tripped and the bail structure moves upward in a printing stroke, permitting the selected actuating bar 108 and the unshift bar 558 to move into the aligned slots. As the movement of the printing bail structure continues the bar 128 will engage the shoulder 111 of the selected actuating bar 108 and the unshift bar 558, causing a printingl stroke of the selected type bar and an upward movement of the cam extension 557. lf the platen is in unshifted position, the upward movement of the bar 558 will have no effect. However, if the parts are in shifted position, the upward movement of the cam extension 557 will move between the roller 556 and the unshift roller 552 and will force the extension 547 and the platen block 489 to the right in Figure 8, before a printing impact of the selected character occurs. So 'long as the characters received are to be printed in the unshifted position, the platen 489 will remain in the position shown. As soon as a character is to be printed in the shifted position of the part-s, bar 501 will be selected and will move to the position shown in Figure 9. In this position of the parts, extension 561 will be moved out of alignment with shift actuating bar 554, and projection 563 will be positioned in alignment with unshift actuating bar 558. As the printing bail structure moves in a printing stroke unshift actuating bar 554 and the selected actuating bar 108 will move into the aligned slots in the selector bars 59 to 63, and will then be moved across the aligned slots by the bail 128. This. effects a printing stroke of the selected type bar and an upward movement of the cam extension 553 which forces the extension 547 forward positioning the platen 488 in shifted position. Platen 488 will remain in shifted position until the selector bar 501 is positioned in unselected or unactuated position for the printing of the character to prevent actuation of bar 554: and causing actuation ofthe unshift bar 558. The parts will then be restored to the position shown in Figure 8 and will remain until another character is to be printed inthe shifted position of the platen.

Accordingly, having described preferred.
