Patented sept; 2o, 1932 UNITED STATES PATENT OFFICE EDWARD E. KLEINSCHMIDT, OF PARK RIDGE, ILLINOIS, ASSIGNOR TO TELETYPE COR- PORATION, F CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE PRINTING TELEGRAPH Application filed November 11, 1925, Serial No. 68,307,

now Patent No. 1,811,132, dated June 23, 1931,which is a continuation of application Serial No. 656,857, led August 11, 1923, Patent No. 1,567,599, dated December 29, 1925. Divided and this application filed January 22, 1931. Serial No. 510,537.

The present invention pertains to improvements in selective mechanisms especially adapted for printing telegraphs, but applicable to other uses.

This application is a division of prior application Serial No. 68,307, filed November 11, 1925, now Patent No. 1,811,132, June 23, 1931, and in the specific embodiments disclosed relates particularly to improvements 'in printing telegraph shift control mechanisms.

It is general practice to provide stock tickets that record in offset lines upon a Wide tape; the letters case characters being recordled on the upper line and the figures case characters being printed on the lower line. The recording of stock designations and quotations results in many more changes from letters to figures and from figures to letters In message Work, permutation code. printers use special code permutations for the shifting operation. If the same method is used for stock tickers the speed of the operator is greatly 1 reduced, and the number of impulses to be transmitted over the line greatly increased; and the transmitting Vcapacity inl characters much reduced.

In the specific embodiments of the present i invention an impulse or case selecting condition is added to the five selecting conditions ordinarily used in printers using the Baudot type of permutation code, and the added condition is used to determine whether the x By thisv means all special shift operations are eliminated on the part of the operator thus materially increasing the speed and accuracy of operation, and a smaller number of line impulses i are required to transmit the -same number of characters thus increasingr the number of characters which can be transmitted ina given circuit. ,v i

The primary object of the present invention thus isto provide. means for printing in offset lines Without using code permutation signals for caseseleoting operations or shifting by addingto the character selecting impulses of each signal a shift or case selectingcondition, the effect of which is to determine Whether a letter case character or a figure case character is to be recorded.

This invention further provides a shift or case control mechanism whereby characters of one group may be 'recorded successively until a character signal of another group is received, the reception of which character Will cause the shifting operation and printing operation to be accomplished appear hereinafter in the detailed disclosure' of preferred embodiments' of the invention and are such as may be attained by utilizing the various combinations and sub-combinations hereinafter set forth and as defined by the terms of the appended claims.

Referring to the drawings: y Figure 1 is a fragmentary sectional elevation showing one form of shift mechanism involving the principles of the invention.

Figure 2 is a fragmentary end elevation of the form shown in Figure 1.

Figure'3 is a detailed fragmentary View showing the shift control selector bar mechanism.

Figure 4 illustrates a section of a stock ticker tape received on the preferred embodiments of the present invention.

Figure 5 is a fragmentary side elevation Since the subject matter in the present case is a division of co-opending application 68,307, filed November 11, 1925, which is a. continuation of the subject matter in application No. 656,857, liled August 11, 1923 and issued as Patent #1,567,599, dated December 29, 1925, only so much of the mechanism shown in said patent has been here disclosed as will be necessary for a complete understanding of the present invention. Accord- -ingly reference characters applied to like parts in the present case are the same as the characters applied to the same parts in the aforementioned patent, which patent may be readily referred to for a full understanding of the various details of the selector and printing 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 set forth in the above'mentioned patent, or may be controlled by selector magnets individual thereto from a rotary distributor in either a multiplex or a start-stop signal printing telegraph system in any manner well know to the art. j

The type bar action comprising the actuating bars 108, arms 113, type bars 116 and the action of the printing ball 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 printing actions will be fully understood by referring to the above mentioned patent.

The mechanism related to the present invention comprises laten block 488 mounted on a head 489 whic is mounted slidably in a guide bracket secured to frame 400. An extension 491 of member 489 is pivotally linked to a rocker arm 492 which is pivotally supported from frame 400 at 493. Ribbon shift pivot 318 is secured to and movable with an extension 494 of arm 492. A sp1-in g 595 connected to arm 492 tends to throw arm 492 with 488 and 489 forward into shifted position.

' Block 488 is just wide enough to be 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 in the shift operation2 are arranged to depress the edges of the tape 1n order to insure contact 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 will be printed, and the ribbon will be properly shifted by the movement of extension 494.

A pin 496, secured to 492, is in slidable engagement with a slot in the end of a shift operating member 497, member 497 is pivoted at a point 498 and urged to the right in Figure 1 by a spring 499, to maintain a 4cam projection 500 thereon, against bar 125 of the rinter bail operating frame. A special shi con-` trol bar 501 is added to notched selector bars 59 to 63, and anl 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 1n the same manner `as the selector bars 59 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, five selector bar control intervals, a shift con- 'trol interval, and a stop interval. The transmitter will be arranged to transmit a marking condition in the shift control interval when block 488 is to be shifted to print an upper case figure, and to transmit a spacing condition when block 488 is to remain in the let- 497 can move into these wide slots with the' selector bars either in actuated o r unactuated position. When a marking impulse is re'- ceived 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 upward, bar 497 will rock on its pivot 498 under the iniuence of spring 499 with cam projection 500 inengagement with bar 125, and will move into the wide selector bar slots. The actuating bar 108 selected by the arrangement of the notched bars will also be moved into its aligned slots. When the two bars have reached the bottoms of their respective slots, bar 497 will have moved to a position which will have caused arm 492 to be moved by spring 595 to shift block 488 into its forward or upper case position. The printing stroke of the selected type bar will then commence and there will be no further movement of bar 497 until the printing has been effected and the selected type bar has returned to normal. Then the return 0r 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 the bars 108 and 497 have been lifted clear of the notched selector bars, member` 77 is actuated by cam 90 to restore the selector bars and the shift control bar 501 to unactuated position, when stop projection 502 will again be positioned under bar 497. Until another code combination, with a marking impulse in the seventh interval is received, bar 501'wi1l be locked in the position shown in Figure 3 b v its Control finger, and platen block 488 will be held tto the rear or in lower case positio as shown in Figure 1.

In Figure a modified form of the invention is -disclosed in which the 'platen and 5 platen carriage construction shown in Figure 3 of said Patent #1,567 ,599 is modified. The platen construction and the carriage are the same as shownin said patent and the tape together with the platen is shifted bodily. A. shift control member 503 suitably plvotedon 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. An actuating projection 506 formed on member 503 is urged into engagement with the printed-operating bail member 125 by the spring 505. Pivotally secured to the lower end of the 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 member503 by means of helical spring 510 which may be coiled around and supported 0n an extension of the pin 507 (not shown). A carriage shift bell crank member 511 is pivotally supported from the frame by means of a pin 512 and is normally urged counter-clockwise by the spring 513, until a project-ion 514 thereof engages the end of the latch member 508. lPivotally secured to the end of one arm of the bell crank member 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 framework and guides and limits member 516 in a reciprocating motion. The upper end of member 516 is adapted to be 4o engaged by the ldwei' surface of the printer actuating bail member 128. Formed on the other arm of the bell crank member 511 are the extensions 519 between which a pin 520 is positioned.v Pin 520 is secured to the member 420 of the platen carriage.

Secured to the member 420 are the ribbon shifting elements 319 and 324,`which shift the ribbon in position for printing when the carriage is shifted as will morefully appear by a. reference to the said Patent 1,567,599. As se-t forth in the copending application projection 415 to the member 420 is adapted to engage the stop screws 442 and 443 and will limit the travel of the carriage. Supported from the member 420 is a carriage positioning roller or member 521 which is adap ed to ride over the projection 522 of the limiting member 523. Member 523 is pivotally mounted and urged preferably by 60- a spring (not shown) into yielding engagement with the roller or member 521.

In operation of this form of the invention the parts are normally positioned as shown and the platen together with the tape (not 6,5 shown) will be positioned to receive printmg impressions of the selected type bars in lower case or unshifted position. 'As the printing bail structure moves to effect printlng strokes in a manner more fully set forth in. the said Patent #1,567,599, the stop 514 w1ll engage the end of latch member 508 and motion of the bellr crank'member 511 under influence of spring 513 will be prevented. When, however, a character in the upper case is selectedfthe shift control bar 501 will be actuated and will shift the projection 502 from beneath the end of the member 503. As the printing bail moves in its print-ing 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. As soon as this disengagement occurs spring 513 will shift the bell crank member counter-clockwise and the right extension thereof will engage the pin 520 and will shift the member 420 together with the platen and tape into the upper case or shifted position. The parts are sol proportioned and arranged that the movement of the platen into the shifted position will be completed before a printing impact of the selected type bar is effected. After the printing of the selected character has been effected the printing bail structure will be returned. as more fully set forth in said Patent 1.567 ,599, and the selected type bar will return to unactuated position. As the printing bail structure returns to normal and moves the member 128 downward the side of member 128 will engage the end of link 516 and will force the bell crank 511 in a clockwise direction. At the same time bar 125 will move the mem- 105 ber 503 until the end of latch 508 drops be-V hind the projection 514 and projection' 502 of the bar 501 is moved to the position shown in Figure 5. During the return movement of the printing bail structure, member 125 110 will engage the cam projection 5,06 of member 503 and will force the end of the member 503 out of the aligned selector bari slots. During this motion of the member 503 the end of t-he latch 508 will engage. the left side or edge of the projection 514 and the latch 508 will move about pin 507 as a pivot until the return movement of the printer bail permits spring 510 to force the latch 508 into position shown in Figure 5. Vhen this occurs the parts will be locked with the platen and tape in unshifted or lower case position.

In the form shown in Figure 6, a further modification of the invention is shown in which the. carriageis moved to the upper case or shifted position by means of a. cam f member and is restored byjmeans of a spring.

In this form the shift actuating bar of thev said Patent 1,567,599 together with the cam extension 433 thereof and the carriage actuut- ing rollers 431 and 436 are retained as set forth in the copendng ap lication. The carriage together with the p aten and tape as shown in Figure 3 of said Patent 1,567,599 is normally held by means of a spring 524 secured thereto and to an extension 525 of a spring-post with the roller 436 carried by the member 420 in engagement with the cam extension 433. Whena selected character' is to be printed in the lower case position the projection 502 of the bar 501 prevents motion of the shift actuating bar 108 into the aligned slots and the platen will remain in the position shown in Figure 6, as printing of the selected character is effected. When, however` the character is to be printed in the upper case or shifted position, in addit-ion to selection ofthe type bar carrying the character to be printed the bar 501 is selected and the shift control bar 108 will move into the aligned slots as the printing bail moves in its printing stroke. As the bail moves in its printing stroke cam member 433 will be shifted vertically and will force t-he carriage together with the. platen and tape into position to receive the upper case or shifted character impression just before the printing impact of the selected tape bar. As the parts restore to normal spring 435 will move the shift actuating bar downward and spring 524 Will effect the. return of the platen carriage to normal or unshifted position as shown in Figure 6.

In the forms of the invention so far described the 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 hercinaftenset forth, the shift mechanism will remain in a given case position until a different position is required for the printing of a succeeding character.

In the form of invention shown in Figures 7 and 8, 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 support-f connected by means of pin 549 to one end of 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 7 engages an edge of. the cam extension 553 of shift actuating bar 554. The opposite edge of the cam extension 553 reacts against a roller, 555 which is pivotally 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 "o 'is held by means of spring 559. Shift and unshift actuating bars 554 and 558 are provided with cam projections 110 and actuating shoulders 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 nnactuated or unselected position pf the bar 501 prevents movement of shift actuating bar 554 to the right in lFigure 7 into the aligned slots 562 off the selector bars 59 to 63 and the actuated or 95 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 movement thereof into the aligned slots 564 of the bars 59 to 63 during a printing stroke of the bail structure and in the unactuated or unselected 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 propel' positioning of the platen 488 in the shifted or unshifted position a bell crank member 565 suitably supported from the frame 400 on a pivot 566 is 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 Vis 115 so proportioned with relation to the roller 552 that the platen will be yieldingly held in either case position by the action of spring 568. which is of sufficient strength to hold the parts properly in either case position but permits shifting of the parts under the influence of the cam members 553 and 557.

In operation of this form of invention when a character is to -he printed in the unshifted or normal position, thes'ele'ction 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 been set up on the selector bars the printing mechanism is tripped and the bail structure moves upward in a printing stroke, vpermittino' the selected actuating bar 108 andthe 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 554, causing a printing stroke of thel selected type bar and an upward movement-of the cam entension 557. If the platen is in unshifted position, the upward movement of .the bar 554 will have `no eii'ect. 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 7 before aprinting impact of the selected character occurs. `S0 long as the characters received are to be printed in the shifted position of the parts. bar 501 will be selected and will move tothe position shown in Figure 8. In this position of the parts, extension 561 will be moved out of alignment'will shift actuating bar 554, and projection 563 will be positioned in alignment with unsliift actuating bar 558. .4s the printing bail structure moves in a printing stroke unshift actuatingbar 554 and the se-,

lected 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. 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 of the unshift bar 558. The parts will then be restored to the position shown in Figure 7 .and will remain until another characteris to be printed in the shifted position of the platen.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodimentv is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention be- "ing indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of theclaims are therefore intended to be embraced therein.

In a receiving register; registering mechanism comprising a plurality of groups of characters; a shift mechanism normally .held in position to cause registration of the characters in one of said groups by means of a spring; means for moving said shift mecha-- nism against the tension of'said spring to reganism normally locked in unsliift position; and means responsive to code combinationsof impulses for selectively operating said character elements and releasing said'shift mechanism for movement to shift position.

27. In a printing telegraph receiver; a plurality of type characters; a shift mechanism; means responsive to a code combination of impulses for selecting one of said type bars for operation and simultaneously conditioning said shift mechanism for operation; and means for operating said selected type character and releasing said shift mechanism for operation. 28. In a. printing telegraph receiver, a plurality of c aracter elements; va platen; a ribbon; a shift bar; and means controlled by said shift bar for simultaneously shifting said platen and said ribbon; and means for 23. The combination as set forth in claim i icc isc y simultaneously selecting one'of said char-V acter elements.

29. In` a printing telegraph receiver, a normally latched shift mechanism selectively controllcd'by an extra impulse following a code combination of impulses; a printing bail; means for releasing mechan'sm for y operation upon movement of said printing bail to print; and means controlled by said printing'bail upon its return to normal for .latching said shift mechanism.

130. In a printing telegraph receiver, a shift mechanism normally latched in unshift position; a shift control bar heilig selectively responsive to an impulse following a code combination of impulses latching said shifting mechanism from operation; a printing bail for controlling said shift control bar to unlatch said shift mechanism; and means controlled by said printing bail for restoring said shift control bar andpositioning said shift mechanism to be again latched by said shift control bar.

31. In a printing telegraph receiver, a plurality of type character elements; a

latched shift control mechanism; means responsive to code combinations of impulses for selecting one of said character elements for operation; a printing bail; means controlled upon operating movement of said printing bail for releasing said shift mechanism for operation and for operating said selected character element; and means controlled by length letter code for operating said memsaid printing bail upon its return to normal` member carrying .type characters in two different rows, a plurality of selecting elements responsive in accordance with an equal length letter code for operating said member to position two type characters in a printing position, a platen, and an additional selecting element responsive to one unit of said code for effecting solely mechanically a rela-` tive movement between said member and said platen to permit the printing of one of said selected characters.

34. In a printing telegraph receiver, a member carrying type characters in two different rows, means responsive to an equal ber to position two of the type characters in a printing position, a platen, and means responsive to one unit of said code for effecting solely mechanically a relative movement between said member and said platen to permit,

the printing of one of the selected characters.

35. In a printing telegraph receiver, a type member carrying a plurality of characters in offset relation, means responsive to an equal length letter code for selecting at least two of said characters for printing, a platen, and means responsive to one unit of said equal length letter code for determining solely mechanically the position of said platen and the printing of one vof the selected characters.

36. In a printing telegraph receiver, a series of'elements divided into two groups, all of the elements in each group having a characteristic peculiar to the group, a series of permutation members, each permutation acting lto select simultaneously an element of each group, and an additional rmutation member cooperating with said series for acting as the sole control to select the group.

In testimony whereof I aix my signature.
