Potts, Evanston, Ill., assigner to Teletype Corporation, Chicago, Ill., a corporation of Delaware Original application May 15, 1939, Serial No. 273,672. Divided and this application May 22, 1941, Serial No. 394,662

(Cl. 17g-34) 31 Claims. 1

This invention relates to telegraphic printing and message posting apparatus and particularly to the recording of stocs quotations and the projection of images of the quotations for display.

This application is a division of application Serial No. 273,672, filed May l5, i939, which eventuated into U. S. Patent No. 2,284,581, dated June 2, i942.

An object of the invention is to reco-rd on a plurality ci tapes in a printing telegraph apparatus all of the quotations pertaining to a selected gro-up of stocks, each of the tapes being assigned to receive all of the quotations with reference to one of the stocks of the group, and to project on a screen current quotations from portions of a group of tapes.

Another object of the invention is to advance each tape across the held of the projecting apparatus only as an incident to the printing of quotations upon that tape so that the viewing screen will thereby present no blank tape in the projection field but instead at all times there will be displayed images of as many quotations on each tape in the field of its projecting apparatus as the area of that field will accommodate.

The invention features printing telegraph apparatus having a plurality of tapes movable in parallel paths and a corresponding plurality of type wheels carried a common shaft for cooperation with said tapes individually. Quotations for stocks not included in the group to be recorded are discarded and have no eect upon any of the printing mechanisms.

The invention also features the division of the horizontally movable tapes in a printer into separated groups, each group having its own source of illumination and optical system, and having images projected therefrom upon its own viewing screen or upon an assigned portion of a large screen independently of the projection of images from other groups of tapes, the several groups of tapes being served by individual type wheels carried by a single type wheel shaft.

In the present embodiment of the invention the type wheels are carried by a single continuously rotatable shaft which extends through and is controlled by a code disc selector mechanism. This mechanism is controlled by a single magnet selector which also controls the setting of code bers. The code bars in turn control the setting of secondary or storage code bars arranged in sets for storing selective conditions identified with the characteristic letters of the stock designations. The storage bars control the selection of printing elements, there being one for each of the tapes, and when the sets of storage bars are positioned for a stock designation outside the group to which the printer is adjusted to respond,

no printing interponent is selected.

rIhe code disc selector device does not arrest the type wheel but merely trips off a printing mechanism which strikes the selected tape against the rotating type wheel, the selected character being printed while the type wheel is lrotating at normal velocity. During the reception and printing of the stock price, the figure shift mechanism disables the storage code bar setting mechanism so that the signals for the price selection cannot interfere with the settings of those bars which have resulted in the selection of a printing interponent.

Tape feeding and ink ribbon feeding operations are performed as an incident to the printing operation. This embodiment of the invention features an arrangement for advancing blank tape past the printing position a suicient distance to bring the last printed quotation into position for observation or projection, and for subsequently drawing back toward the printing position the projected portion of the tape which had previously been advanced. Accordingly, when a next quotation is to be printed upon a tape which has been moved out for viewing the tape is retracted so as to print the new quotation closely adjacent to the one previously printed in order that as many quotations as possible may be contained in the length of tape that is within the field of observation or of the projecting apparatus.

In accordance with one embodiment a projecting system is employed which features compactness as one of its primary considerations and involves the use of a plane reflector for turning a beam of light through degrees whereby the optical system and the printer may be contained in a housing requiring a minimum of space from front to back.

A complete understanding of the invention may be obtained from the following detailed description, reference being had to the accompanying drawings wherein:

Fig. 14 is a view of a fragment of a tape upon which characters have been printed by means of the'type wheel shown in Fig. 13, the tape being viewed from the front'.

Referring now to the drawings, a multiple tape stock quotation printer is shown in Figs. 1 to 12, inclusive. This printer is adapted to the projection of enlarged images of the printed tapes upon screens, as shown in Figs. 11 to i4, inclusive. Referring to Figs. 1, 2, and 3, the reference numeral 40| designates a motor, the rotor shaft 462 of which carries a pinion 403. Pinion 463 has direct driving engagement with a gear 434 secured to type wheel shaft 466 and with a' gear 401 secured to a combined selector and printing shaft 408. Shafts 466 and 468 are rotatably supported by stationary frame portions of the printer. Gear 451 has secured thereto a gear 469 with which meshes a gear 4H carried by a Vtransfer shaft 4|2 rotatably supported in brackyets 4|3.

The arrangement of shafts and gears is similar to that disclosed in U. S. Patent No. 2,247,408, issued July 1, 1941, to Albert H. Reiber.

Shaft 468 has sleeved thereon at its upper end `a selector cam sleeve 4|6 to which rotation is imparted from shaft 468 by means of cooperating driving and driven discs at the end of sleeve 4|6, felt, or other resilient discs being interposed between the driving and driven discs. Selector cam sleeve 4|6, in cooperation with selector magnet 4|1, controls the setting of sword levers in a sword and T-lever selector mechanism indicated generally by the reference numeral 4|8. Selector cam sleeve 4|6 has a plurality of cam projections 4|9 (Fig. 1) which individuallyvand successively bring sword levers 42| (Fig. 4) into cooperation with a selector lever 422, the selective positions of which are controlled by Van arma-l ture lever 423 which carries an armature 424 for the selector magnet 4I1. The single magnet sword and T-lever selector mechanism is well 4known in the art of printing telegraphy, and the 'specific embodiment shown herein is disclosed.

in the hereinbefore mentioned patent of Albert H. Reiber. The sword levers 42| are selectively positioned in extreme clockwise or counterclockwise positions by means of said mechanism and fare thereafter moved endwise to establish corresponding selective positions of transfer levers -426'under the control of a transfer mechanism.

The transfer mechanism comprises a bail 421,

Fig. 2, at the upper end of which is secured a bracket 426 which retains a plurality of transfer springs 429. Springs 429 are effective upon the individual sword levers 42| when bail 421 is operated to move the sword levers to their extreme right-hand positions, as viewed in Fig. 4. Bail 421 has secured thereto an arm 43| which is provided with a locking blade 432 which normally locks projecting ends of transfer levers 426 and which is withdrawn due to clockwise rotation of arm 43| when bail 421 is operated to permit the selective resetting of transfer levers 426.

Transfer bail 421 carries a cam follower roller (not shown) which engages a cam 434 secured to a cam sleeve 436, sleeved on the transfer shaft 4|2. Rotation is imparted to cam sleeve 436 through a spring loaded jaw clutch 431 which is normally held disengaged by a clutch throwout lever 438. Lever 433 is carried at the lower end of a bail 433 which carries at its upper end an operating arm 44| disposed in the path of a cam projection 442 (Fig. 1) included in selector cam assembly 4|6. A tension spring 443 biases clutch throwout lever 438 into engagement with clutch 431 and the end of operating arm 44| in the path of cam projection 442. Upon each operation of clutch tripping bail 439, cam 434 is released for a single revolution and operates its follower which through arms 43| and 421 unlocks transfer levers 426 and repositions them in accordance with a new signal combination under the control of sword levers 42|.

Stock quotation printers are usually operated under the control of a 6-unit code, one impulse of which determines Whether figures or letters shall be printed and the remaining live of which select the particular letter or figure to be printed. 1n conformity with this practice, the printer now being described is provided with five of the transfer levers 426, each of which has disc and slot articulation with an intermediate three-armed lever 443 (Fig. 4) of which there are ve disposed one above the other upon pivot 444. Each of the intermediate three-armed levers 443 has one of its arms disposed in a slot in a code disc 446, of which there are five permutation code discs (Fig. 3) and a special blocking disc 441 (Fig. 4) included in a code disc selector mechanism indicated generally by the reference numeral 448 (Figs. 3 and 4). The third arm of each of the three-armed intermediate levers 443 terminates in a disc portion which is disposed in a slot near the end of a code bar 449V of which there are live (Figs. 1 to 4, inclusive). Pivot 444 also supports a lever 45| which is operatively in The engagement with special blocking disc 441. function and control of'lever 45| will be described later. y

It will be apparent from the foregoing that when transfer levers 426 areset permutatively acing to that impulse of the code combination which identifies the code combination Aas pertaining to letters or gures. The sixth sword lever is aligned with and controls a T-shaped lever 452 which is pivoted coaXially with the transfer .levers 426. The T-shaped lever 452 has its principal arm 453 disposed between pins 454 and 456 Afrom arm 455 of lever 45?.

into engagement with a ratchet wheel 462 secured at the upper end of shaft 453. Lever 45'! is biased in clockwise direction by spring 455 (Fig. 1) engaging an arm 455 of lever 457 and urging Athe arm into engagement with a stop post |4513. Bell crank 455 is biased in counterclockwise direction by spring engaging arm 470 Vof bell crank 453 and urging the arm into engagement with post i455 on the opposite side Stop post i455 is so positioned that T-shaped lever is normally retained by the lever 45'! and bell crank 453 in a position intermediate the positions to which it may be rocked by its associated sword lever 421. The rocking of T-shaped lever 452 to either of kits eXtreme positions is effected by the transfer bail 421 which moves sword levers 425 endwise rightwardly, as viewed in Fig. 4, and thus momentarily rocks T-shaped lever :352 to extreme clockwise or counterclockwise position while at the same time setting transfer levers 42S permutatively. As the transfer bail returns to nor- `mal position, it ceases to exert any effect upon combinations is such that when the combination e pertains to the letters of a stock quotation designation, T-shaped lever 452 is rocked in clockwise direction and, in turn, rocks pawl supporting lever 45? counterclockwise to effect counterclockwise rotation of rock shaft 453 one ratchet step. A holding pawl 454 is urged into engagement with ratchet 452 by a spring (not shown) to hold ratchet wheel 4? in its normal position or in any advanced position to which it may be rotated by pawl 459.

Shaft 453 is biased in clockwise direction, as viewed in Fig. 4, by means of a torsion spring 456 (Fig. 3) and is provided at its lower end with cams 45E', 45B, and 455 and with a stop disc 4H. Stop disc 4?! is provided with a shoulder which is engageable with a xed bracket 4'52 of the frame of the machine to arrest shaft '53 when ratchet wheel 4t2 is engaged by neither of the pawls 459 and to determine the rest position thereof.

Cams 45? to 455, inclusive, are provided for controlling the setting of three sets of storage code bars according to permutational settings of the code bars As shown in Figs. l, 3, and 6, a series of endwise movable bars 453, 414 and 416 is disposed adjacent to the cams 45? to 45), inclusive. Bars 4l3, 4'1'4, and it are disposed one above the other corresponding to the spacing of cams 45? to 455, inclusive, and each of the bars pivotally supports an interponent lever 4H', 418, and 4215, respectively, which levers are aligned horizontally with cams 457, 455, and 465 respectively and are urged into engagement with the cams by springs, such as 48! (Figs. l and 6). Cams 4E? to E58, inclusive, are provided with recesses as at 432, 459, and 453, respectively (Figs. 1 and 6) which may be entered by the cam engaging ends of interponent levers 4l? to 479, respectively, when cams 4S? to 455, respectively, have been rotated into position to present their recesses. The angular disposition of cams 461 to 45,9, with reference to their individual nterponent levers 4?'1 to 459, respectively, is such that when shaft 453 is in normal position with the shoulder of stop disc 47| engaging fixed stop 412, none ofthe recesses 482, 435, and 483 is presented to an interponent lever. When ratchet 452 has been advanced one step in counterclocliwise direction cam 45t is rotated sufficiently to bring its recess 432 into alignment with the cam engaging end of its interponent lever 47?, which responds to its spring 43! and enters the recess 482, the interponent 4'1'7 thus rotating in clockwise direction, as viewed in Fig. i. When ratchet 462 is rotated another step in counterclockwise direction by pawl 459, the recess 452 in cam 467 is moved out of registry with the cam engaging end of interponent 4W and the recess S5 in cam 4% is presented to the cam engaging end of interponent 'i. Similarly, when shaft is rotated another ratchet step in counterclockwise direc- .ion, interponent 478 is restored to its normal position by the movement of the recess 485 in cam 458 out of registry with the interponent, and recess in cam 455 is presented to the cam engaging end of the lowermost interponent 47B.

Adjacent to the left-hand end of the bars 413, 414, and 476, as viewed in Fig. 3, is the depending arm 484 of a bail 485 pivoted at 451. Bail 485 is provided with a cam follower roller 458 which engages a cam 489 included on cam sleeve 435 carried by transfer shaft 4I? and driven by clutch mechanism 431. When cam 489 is rotated, bail 455 is rocked counterelockwise, as viewed in 3, and its depending arm 484 is moved rightwardly a predetermined distance and is then restored to normal position, which is that shown in Fig. 3, by tension spring 49. Bail arm 484 clears the left-hand ends of bars 473, 474, and 4i5 as it moves rightwardly, but the left-hand end of any of the interponent levers 4T?, 418, and 479, which is rocked in clockwise direction due to entrance of its cam follower portion into a recess in its corresponding cams 457, 463, or 455, moves into the path of bail arm 484, and as the arm is moved rightwardly, rightward motion is imparted to the bar 413, 414, or 425 by which such interponent is carried. The right-hand ends of bars 413, 4'54, and 416 are step Cut so that they may individually engage depending operating arms of nested bails 452, 493, and 454, respectively, pivoted upon shaft 45S.

Previous reference has been made to sets of storage code bars. There are three such sets, the rst set being designated 513i, the second 502, and the third 583. Storage code bars 50i, 552, and 553 are individually supported near their lower ends by being provided with two pins 504 and 595, Fig. 3, between which extend horizontal arms of transfer bell cranks 557, there being a transfer bell crank individual to each of the storage code bars. As the storage code bars are arranged in sets, so also are the transfer bell cranks 557, those individual to the code bars 59! being pivotally supported as at 558 in a transfer bail 559, those individual to Code bars 552 being pivoted at 5H in a transfer bail 5l? and those individual to the code bars 5i3 being pivoted at 553 in a transfer bail 5i4. Bails 55d, SI2, and 554 are pivoted upon pivot rod 555, and each has a depending operating arm, the arms being designated 5H, 5w, and 5l9 for the bails 5tlg, 5i2, and 5l4, respectively. Adjacent to the lower ends of the bail arms 5H, 518, and 5&9, bails 452,493, and 494 are provided with laterally exmal condition, a fixed stop 534.

tending projections 52|, 522 and 523, respectively, in the operative path of which the lower ends of bail arms 511, 510, and 519 are disposed. As viewed in Fig. 3 upon the rightward reciprocation of any of the bars 413, 414, and 416, its corresponding bail 492, 493, or 494 will be rocked counterclockwise and will, in turn, impart counterclockwise rocking movement to the corresponding bail 509, 512, or 514 through its depending arm 511, 518, or 519, respectively.

Storage code bars 501, 502, and 503 are individually urged downwardly by means of tension springs 524 (Fig, 3) to seek engagement with a stop rail 526. These bars are movable under the control of transfer bell cranks 501, as will presently be described, from their lowermost positions engaging the stop rail 526, which is one of their selective positions, to an upper and therefore alternative selective position, in which position they are held by individual latches 521 pivoted on a pivot rod 520 and biased in clockwise direction, as viewed in Fig. 3, by individual tension springs 529. The clockwise movement of latches 521 when their individual bars 501, 502, and 503 have been lifted free of those latches is limited by a bail 531 which is also pivoted upon rod 528 and which spans all of the latches 521. When any of the bars 50|, 502, and 503 is lifted to its upper selective position, it rests upon its associated latch 521, which has been moved in clockwise direction by its spring 529 and which remains in that position until retracted to permit the storage code bars 501, 502, and 503 to return to normal position.

The retraction of latches 521 is accomplished by bail 531 which has at its left-hand end, as viewed in Fig. 1, a depending arm 532 which terminates close to the upper surface of reciprocable bar 413, Bail 531 is biased clockwise by tension spring 533 (Fig. 3) to engage, in the nor- Reciprocable bar 113 has pivoted upon the upper surface thereof as at 536 a trip-off lever 531 (Figs. 1 and 3) which consists of two arms, one extending along bar 413 and terminating adjacent the lower end of latch tripping bail arm 532 which is disposed in its path, and the other extending transversely from bar 413 and having in its path a xed pin 538 (Fig. l). A spring 1531, Fig. 6, maintains lever 531 in its extreme clockwise position resting against a stop lug integrally formed with the bar 413. Upon rightward reciprocation of bar 413, as viewed in Fig. 3, the end of the arm of trip-oif lever 531 which extends along bar 413 engages latch restoring bail arm 532 and rocks the bail counterclockwise to withdraw latches 521 from supporting engagement with any of the storage code bars 501, 502, or 503, that may be in their uppermost selective position. As trip-off lever 531 continues to be carried rightwardly by bar 413, its laterally extending arm engages pin 538 and the trip-off lever is rocked counterclockwise, as viewed in Fig. 1. The counterclockwise rocking of trip-off lever 531 causes it to be withdrawn from engagement with the lower end of latch restoring bail arm 532, and spring 533 restores bail 53| to extreme clockwise position, as viewed in Fig. 3, in engagement with stop 534. Upon retraction of bar 413 to normal position, the tripoif lever 531, after being withdrawn from engagement with bail arm 532, returns to extreme clockwise position, as viewed in Fig.'5, in readiness to rock unlatching bail 531 upon the next operation of reciprocable bar 413.

As shown in Figs. 4 and 7, each of the bars 449 and arranged to block simultaneously or to un-v block a corresponding one of the transfer bell cranks 501 in each set 501, 502, or 503. Thus,

the uppermost of the bars 449 has projections 541 which will block the first transfer bell crank in each group, counting from the left, as viewed in Fig. 4, and these lugs will be moved out of blocking relation to the particular bell cranks 501 when the uppermost bar 449 is moved to its other selective position. Similarly, the bar 449 next below the top has three lugs 541 which will block the second transfer bell crank 501 in each group counting from the left when the bar is in one selective position and which will not be in the path of those bell cranks when the bar is moved to its other selective position. Fig. '1 shows in detail the relation of the lugs 541 to one set of transfer bell cranks 501. It should be noted that none of the lugs 54| carried by the bars 449 can block one transfer bell crank 501 when in one selective position and another of the bell cranks when in another selective position. The movement of bars 449 from one to another of their selective positions is sufcient only to move its lugs into or out of locking relation with respect to particular transfer bell cranks.

It will be apparent that when latches 5.21 are withdrawn to their extreme counterclockwise positions, as viewed in Fig. 3, and all of the storage bars 501, 502, and 503 are permitted to rest upon the fixed stop 526, the transfer bell cranks A501 associated with those of the bars 501, 502, and 503 that had been previously elevated will be rocked in counterclockwise direction. Stop 526 is so positioned that the upwardly extending arms of transfer bell cranks 501' cannot thereby rock into engagement with the lugs 541 carried by bars 449, and thus there will be no interference with the setting of these bars by the three-armed intermediate levers 443. As the reciprocable bar 413 moves to its extreme rightward position (Fig. 3), it rocks transfer bail 509 to extreme counterclockwise position, thus carrying the five transfer bell cranks 501 supported thereby to the left. Those of the transfer bell cranks 501 carried by bail 509 that do not encounter lugs 541 are merely moved leftwardly idly, their horizontally extending arms moving between the pins 504 and 506V of storage bars 50| without in any way affecting the storage bars. However, those that encounter lugs 541 have their upwardly extending arms arrested by the lugs and as bail 509 continues to rock in counterclockwise direction, the blocked transfer levers 501 are rocked in clockwise direction to lift their associated storage bars -501 against the tendencies of their individual springs. The bars that are lifted, clear their latches 521 which respond to their springs 529 and move into position to support the lifted storage bars. In

this manner, the storage bars 501 are set in positions corresponding to the selective positions of the bars 449. c

Storage bars 502 and 503 may be set accordin to the next two signal combinations in the same manner, the setting of the bars being accomplished by reciprocable bars 414 and 416 under the control of cams 468 and 469. In this manner, there may be stored in the storage bars 50|, 502, and I5133, code combinations representing three successively received letter codes.

The sets of storage code bars 501, 502, and 503 control the selection of any one of a plurality of selectable slide bars 551 in a manner similar to va selecting system disclosed in copending application Serial No. 333,161, filed January 17, 1929, by L. M. Potts. Referring now particularly to Fig. 3, it will be observed that the bar 5B1 seen in elevation is provided with a uniform distribution of notches and lugs. The space occupied by one lug and an adjacent notch corresponds to that required by any one oit the plurality of tapes upon which printing is to be effected. In this space is accommodated one of the selectable slide bars 551, there being one such bar for each tape upon which characters are to be printed. `All of the bars Eiii, V592, and 553 are identical with the bar 50! shown in elevation in Fig. 3 in that they are provided with a uniform distribution of notches and lugs. Thus7 there is no permutational or other coding inherent in the notchings of the several bars 551, 552, and 553. Slide bars 55| are shown in their extreme right-hand position in Fig. 4, and these bars are slidable leftwardly under circumstances about to be described, the leftward movement being imparted by tension springs 552 individual to each bar 551. `rEach of the bars 555 is provided with three sets of notches, each set consisting of iive notches. The slide bars 55! are so positioned with reference to storage bars 5M, 552, and 553 that the front edges of the storage bars are disposed in the notches in bars y554, the front edges of the storage bars being the edges provided with the uniform distribution or notches and lugs, There are thus provided upon bars 555i a plurality of lugs or ears 553. With reference to any of the storage bars 55, 552, and the lugs 553 disposed at the right of individual storage bars, as viewed i in Fig. a, are the ones which may prevent leftward movement of a slide bar 551.

As shown .in Fig. 3, the lugs 555 of slide bars 55! are bent upwardly or downwardly according to a permutation code system whereby a bar Sill, 552 or 553 may have certain of its lugs interposed in the path of lugs 553 oi certain of the slide bars 55! when the storage bar is in its upper selective position and may have others of its lugs interposed in the path of lugs 553 carried by the remainder of the slide bars 558 when the storage bar is in its lower selective position. From this, it will be apparent that for a given permutational setting of the storage bars 555, 552, and 553 in upper and lower selective positions one, and according to the preferred embodiment of the invention only one, of the slide bars 55! will have all of its lugs in alignment with notches in the storage bars whereby the slide bar will have been selected and will be free to move leftwardly, as viewed in Fig. 4. With a diierent permutational setting of the storage bars 513i, 55E, and 5135, another one or none of the slide bars 55! may be selected for leftward movement.

lAs is well known in printing telegraph systems operable in accordance with permutation codes, five selecting bars will afford thirty-two usable selective possibilities. This is true of any oi the sets of ve storage bars 555i, 552, and 553. With three such sets jointly controlling the slide bars 551, the number or selective possibilities is very much higher than can possibly be employed in a single printer. rThis arrangement will permit the coding of the slide bars 555 according to the actual letters of the stock designation. Thus, the 'oars 55S may be set according to the code combination for the rst letter or" the stock, bars 552 may be set in accordance with the code combination for the second letter of the stock, and

bars 553 may be set according to the combination` of the third letter of the stock designation. Some stock designations are customarily represented by two letters and some by a single letter. For quotations relating to such stocks, it will be necessary to set permutationally only the storage bars 55! and 552 or only the storage bars 553i. Since prior to the setting of the bars 551 all of the latches 527 are retracted to permit all of the storage bars to .return to their lowerrnost positions, those quotations which contain no second, or second and third letters will not involve permutational settings of the storage bars 552 or 552 and and those bars will remain in their lowermost positions. For such stocks, the slide bars will necessarily be coded to be selectable when the storage bars 552 and 553 are in their lowermost positions and such slide bars will be blocked when a storage bar from a set for which the stock designation has no identifying letter is raised to the upper selected position. For settings or" the storage bars corresponding to designations of stocks other than those for which tapes have been provided in a particular printer, no slide bar 555 will be coded to be selected, and as the printing of a stock price occurs only as a. consequence of selection of a slide bar 551, the unwanted quotation will be rejected, as will presently appear.

At the left of each of the slide bars 55l, as viewed in Fig. e, is a combination print hammer and tape feeding control slide 555 and a pivoted latch 557. Each print hammer slide 556 is provided with a notch 558 to be engaged by the latch 55's'. Frint hammer slides 555 are urged leftwardly by springs 55S and are restored to their extreme right-hand position by a bail 55! which is engageable with a hooked arm 552 carried by each of the slides 555, and is biased to seek-engagement with the hooked arms 552 by a spring 555 which is very light as compared with the springs 55S.

As may be observed by reference to Figs. 1 to 4, inclusive, bail 55! extends transversely of all of the print hammer slide restoring arms 552 and is pivoted at 553. Clockwise rocking movement is imparted to bail 55! to effect the restoration of slides 555 to their eXtreme right-hand positions, as viewed in Fig. 4, by a bail 555 pivoted at 565 and connected to bail 555 by means of a link 55?, the connection between bail 55l and link 557 being a pin 558 and slot 559, as shown in Figs. 1 and 4. Counterclockwise movement is imparted to bail 55| by the individual print hammer slides 55.5 which are moved leftwardly by their springs 559.

The lowermost end of bail 555 is disposed adjacent to the right-hand edge of the uppermost reciprocable bar dit and the bail is provided with a roller 5l! the horizontal plane of the reciprocable bar 553. As shown in Fig. 6, bar 413 has a portion at its lett-hand end of greater width than the main body portion of the bar, and when the bar is in its normal or unoperated position, roller 555 engages the edge of bar 475 in the main body or narrow portion thereof. When bar 413 is moved rightwardly, as viewed in Fig. 3, in the manner previously described, roller 57i rides up the slope between the narrow and the wide portions of bar 555 whereby clockwise movement is imparted to bail 555 and through link 561 to 552, by engagement of the left-hand end of slot 555 with pin 558. This movement of bail 55S by means of said bar 73 thereupon causes movement of any hammer interponent assembly 556 which had been released, restoring it to its la-tched position as shown in Fig. 4:

Adjacent to the portion of bail 56| which engages print hammer slide restoring arms 562, the lower arm of the bail pivotally engages a link 512 which has intermediate its ends a notch 513. A latch 514 pivoted at 468 and biased in clockwise direction by a tensionspring 515 enters notch 513 in link512 when bail 56| has been rocked to extreme clockwise position and retains the bail in that position. The slides 556 are held in their extreme right-hand positions, as viewed in Fig. 4, by their latches 551 and by the latched bail 56|. Tension springs 552 urge slide bars 55| into engagement with their associated slides 556 so that when a previously selected slide 556 is restored to its eXtreme right-hand position, its associated slide bar 55| will also be restored to extreme right-hand position. As reciprocable bar 413 returns to its normal position, bail 564 is moved by its restoration spring 565 to its extreme counterclockwise position with its roller 51| engaging the narrow portion, the pin and slot connection between link 561 and bail 56| permitting this independent movement.

The release of bail 56| to permit a selected one of the slide bars 55| to trip its associated latch 551 and thereby release its associated print hammer slide 556 for leftward movement, as viewed in Fig. 4, is controlled by the previously identified T-lever 452. Upon the reception of a code combination which contains an impulse to controlrthe printing of figures, T-lever 452 is rocked counterclockwise, as viewed in Fig. 4, and

through pin 456 it rocks bell crank 458 clockwise.

Bell crank 458 has an arm 516, the free end of which is disposed in a slot in disc 511 which is sleeved on shaft 463 below ratchet 462. Disc 511 supports upstanding pins 518, one of which is adjacent to pawl 459 and the other of which is disposed adjacent to holding pawl V464 and to an arm of a bell crank 519 disposed above and extending parallel to holding pawl 464, the bell crank 519 and pawl 464 both being pivoted at 469. When bell crank 458 is rocked clockwise by T-lever 452, disc 511 is rotated counterclockwise a suicient distance to cause pins 518 to withdraw operating pawl 459 and check pawl 464 from engagement with ratchet 462. rocked counterclockwise through the same angular distance as is pawl 464. Upon the release of the pawls 459 and 464, spring 466, Fig. 3, restores shaft 463 to normal position with the shoulder on stop disc 41| engaging iixed stop 412.

` Bell crank 519 has an arm 58| which carries a pin 582 disposed adjacent to the end of latch 514 which holds bail 56 in eXtreme clockwise position. Pin 582v also engages one arm of a bell crank 583 which is pivotally supported upon an arm |583 of shaft 6 |1 in association with a printing bail 584, the structure and operation of which will be described later. The free end ofthe other arm of bell crank 583 is provided with a latching shoulder which engages an extension 585 of the lever 45| which controls special blocking code disc 441, and the latching shoulder normally holds the lever 45| in extreme counterclockwise position whereby disc 441 is normally presented in eX- treme clockwise position. Latching bell crank 583 is disengaged from the extension 585 of disc controlling lever 45| by pin 592 as bell crank 519 is rocked counterclockwise, but lever 45| is not thereby released for the reason that it is held by a second latch 586 pivoted at a, xed point 581. At its foremosten'd, as Viewed in Fig. 4, latch 586 Bell crank 519 is 12 carries a pin 588 which is disposed in a slot589 in the left-hand end of link 512. Since link 512 is moved leftwardly with bail 56| when the latter is moved counterclockwise by a selected and released print hammer slide 556 upon the release ol latch 514 it moves idly with respect to pin 588 carried by latch 586 until the right-hand end of slot 589 engages the pin 588. Further leftward movement of link 512 causes latch 586 to be with-'- drawn from engagement with lever 45| which, being biased in clockwise direction by a spring 59|, rotates its associated discv441 in counterclockwise direction.

Disc 441 is provided with notches spaced according to the spacing of selectable pins 592 of code disc selector mechanism 448 (Fig. V 4). When disc 441 is in extreme clockwise position it blocks all of the pins 592 and prevents any one which may otherwise have been selected bycode discs 446 from moving inwardly radially of code disc selector mechanism 448. When disc 441 is rocked to extreme counterclockwise position upon release of latches 583 and 586, it presents its notches to all of the selectable pins 592 and any such pin to which an alignment of notches is presented by the five code discs 446 is permitted to move inwardly radially of selector mechanism 448.

The two latches 583 and 586 are provided because the control of blocking disc 441 involves several factors. Latch 583 is released upon the transfer of a signal combination in which the sixth pulse is of marking nature. Due to the association of latch 583 with the printing bail, the latch is reengaged with and relatches the lever which controls disc 441 after each printing operation, the purpose of this being to prevent a second printing of a character in response to one selection of that character. Latch 586 is released by the latch link 512 of bail 56| at the time that bail is moved into its extreme counterclockwise position by a selected print hammer slide 556, the slide having moved into effective position at that time. It thus delays the unblocking of the print-- ing control pins 592 to insure the operation of the print hammer slide. The latch 586 remains released until the selected slide 556 is retracted to ineffective position. The restoration of any one of said slides 556 is eiected through the operationy of bail 56| as has already been stated. A

The movement of bail 56| in a clockwisedi` rection about its pivot 563 is preceded by the operation of printing bail 584 which member, in effecting printing, rotates clockwise about its shaft 6|1 until bail blade 626 is brought sharply against the interponent hammer 594 of the particularly selected slide 556, whereby printing is effected through percussion engagement with an associated type Wheel 599. Upon the restoraftion of printing bail 584, however, which result is roller 628, shaft 6 |1 and all of its integrally associated elements is rocked counterclockwise, and

as an incident thereto aforementioned arm |583,

' Fig. 1, which carries a latching-bell crank 583 and which had been retracted during the printing motion of bail 584 is now rocked counterclockwise as bail 584 is retracted so that the shoulder of bell crank 583 may again engage portion 585 of blocking disc operating arm 45| and rock the latter in a counterclockwise direction about its shaft444 returning the selector block` ing disc 441 to its effective position as indicated ini Fig. 4.

Latch 586 is also effective to prevent) Y. the operation of the printing bail 584 when stock price signal combinations are received for stocks for which no coded slide bars or recording tapes have been provided. There will be no print hammer slide selected or released when the identifying letter signals for such stocks are received, and therefore bail 5e! will not be rocked counterclock- Wise nor latch {i be tripped when the figure signals are received. Blocking disc filii will therefore be retained in blocln'ng relation to pins 5e?, one of which must be selected in order to cause operation of the printing bail. Preferably latch 583 holds extension 585 of lever 45| slightly iarther counterclockwise than does latch 586, as the latter is required to engage and hold the extension, after the release of latch in such position that should latch 583 return to normal position before the release of latch 586, the latch 583 cannot relatch the extension nor otherwise deprive latch 536 of its proper control over blocking disc 4117. f

Each of the print hammer slides 55E carries a flexible arm 593 at the left-hand end of which (Fig. 4) is a print hammer head 5%. Intermediate the ends of each slide 555 a spacing control pin 59B is reciprocably supported, the pin being maintained in retracted position by a compression spring 597 which is compressed between one of the supports for pin 5% and a flange 5&8 carried by the pin. The movement of print hammer slide 55S leitwardly, as viewed in Fig. 4, when permitted by the release of bail 56| and by the release of the latch 557 under the control of a selected slide bar 55|, is suicient to bring the print hammer head Eet into printing position between the type wheel 599 and print hammer operating blade 526 of print bail 58d, and to bring the spacing control pin 555 into alignment with the operating lug 613| of a spacing paw] 82. The apparatus is now in readiness for the printing of the gures of a stock quotation, the stock designating letters having served to elifect the selection of a particular print hammer slide 55S and during the reception of the letters code combinations, the code disc selector pins 592 having been blocked and prevented from responding to the letters selections by means of the special blocking disc 447.

The type wheels 599 are secured to type wheel shaft m5, which is continuously rotatable. Ad-

jacent to the top of code disc selector mechanism 448, type wheel shaft carries in fixed angular relation to the type wheel an arm 6%3 (Figs. 3 and 9) At its outer end arm 653 pivotally supports a print bail controlling lever 5534. Lever E54 is provided at its outer end with an obliquely directed extension 5&7 which trails the lever Eil as arm S rotates. Extension 5137 of lever 594 revolves about the axis of shaft etti just inside the alignment of selectable pins 592 when those pins are in their outermost or unselected positions. When all of the selectable pins 592 are blocked by the special disc l, arm GES and lever 664 revolve idly as shaft et rotates and the trailing extension 697 oi lever does not come into engagement with any of the pins 592. However, upon the selection of one of the pins 592, its upper end is moved into the path of obliduely disposed extension 5&7 of lever 504 and when the trailing extension comes into engagement with the selected pin, it rides over the top of the pin, 7

thus rocking lever Et countercloclcwise, as viewed in Fig. 3, and thereafter drops oi, permitting the lever to return to normal position.

Above the code disc selector mechanism 48, shaft e8 carries a sleeve 638 which is urged upwardly by a compression spring 609. Sleeve 8 is provided with spaced anges 5| l. The inner end of lever 64 is disposed between two of the flanges 5H so that when lever tell is rocked counterclockwise (as viewed in Fig. 9) by one of the selectable pins 5&2, sleeve 663 is moved downwardly along shaft lille, thereby compressing spring tl. The free end of a latch 6i? pivoted at 613 is disposed between two of the discs 6| so that when sleeve lit is moved downwardly, latch BlZ will be rocked clockwise, as viewed in Fig. 3.

Latch is provided with a vshoulder which normally holds printing bail arm i585 in the position shown in Figs. 4- and 5, the bail being biased in clockwise direction against the shoulder by a tension spring ti@ (Fie. 5) connected to an arm 5| E secured to the shaft 6 i 7 to which printing bail 584i is secured. Arm Sie is disposed in the same horizontal plane as a bail restoring cam l l 8 which is carried by main shaft dil@ and is connected to the shaft through a friction clutch. Above the cam il and connected thereto for controlling the rotation is a stop disc tlg which is provided with stop shoulders equal in number and spacing to the number of bail restoring apices with which cam 558 is provided. A sto-p pawl 62| is pivoted at 622 in the same horizontal plane as stop disc 659 and is urged by tension spring 623 into engagement with the stop disc. At the opposite end from that which engages stop disc 5|9, stop lever $24 is provided with a depending pin i524 which is disposed in the path of printing bail arm 'l when the latter is rocked in clockwise direction.

Upon the release of latch Sill, printing bail 584 is rocked. in clockwise direction by spring 554 to cause blade 26 carried by bail 584 to strike a selected print hammer head 55d to cause it t0 strike against type wheel a tape upon which printing is to be effected and an ink ribbon being interposed between print hammer head E94 and type wheel as will appear hereinafter.

As the printing stroke is performed, a roller carried by the free end of bail restoring arm tit is brought into engagement, with restoring cam M8. Restoring arm Ei' in moving to its eX- treme clockwise position rocks stop lever 52| counterclockwise, as viewed in Fig. 4:, due to engagement with its depending pin Sie. Stop lever 62%y is thus withdrawn from engagement with a shoulder of stop disc SEQ and rotation is imparted to cam tit and disc ifl by shaft 38. The rotation of shaft 1298 is in clockwise direction, as viewed in Fig. 5, and cam |558 rocks lever arm 6l 5 and therefore bail 535i counterclockwise a distance greater than that required to re-engage it with latch e l L. the overtravel in counterclockwise direction being provided for the control of tape spacing as will presently be described. As bail restoring arm Elli is rocked c-ounterclocliwise, it is withdrawn from engagement with depending pin 52:3 of stop lever 2i which is thus enabled to return to engagement with Stop disc Elli to arrest the disc by engagement with the next succeeding shoulder carried thereby. Cam dit and disc i are not arrested until after a restoring apex cam B! 8 has passed and moved free of roller 529 whereby arm il returns in clockwise direction from its limit of overtravel until bail l engages the shouldf on latch The bail Ete is thus prepared for the next release of latch El? when it can he rocker.' in clockwise direction by spring tid, printing thus being 'oy spring and restoration by cam, from which roller i523 is held disengaged in normal or idle condition.

As previously stated, each of the type wheels carried by shaft 466 has associated with it a tape upon which quotations are to be printed.` The tapes, identied by reference numeral 636, are supplied from individual tape rolls 63|, each of which is supported, as shown in Fig. 10, on an individual arm 635 pivotally supported on a vertically disposed post 646. Adjacent arms 635 on post 640 extend on opposite sides of a limit bar 645 against which they are biased by individual springs 656, the leitwardly extending arms in counterclockwise direction and the rightwardly extending arms in clockwise direction. Tape guides 655 may be provided for guiding the individual tapes from their respective supply reels to their tape feed control rollers 632 with which the tapes are frietionally engaged by pressure rollers 633.

With the arrangement described in the foregoing paragraph two vertical alignments of tape supply rolls are provided, a space intervening any two adjacent supply rolls on one side of limit bar 645, due to the alternate disposition of successive supply rolls on opposite sides of bar 645. The space provided aords access to individual supply roll supports, and an exhausted supply of tape may be replenished by swinging the particular arm 635 away from limit bar 645 and clear of the other supply rolls on the 'same side of bar 645. Thus, the supply rolls are individually and independently supported, and may be replaced without disturbing any other supply rolls.

The tape feed controlling rollers 632 are mounted one above the other on a stationary shaft 636 and are individually rotatable upon the shaft. Each feed roller 632 has secured thereto a ratchet wheel 531 which is engaged by the previously identified escapement Vpawl 662. Each of the pawls 602 is biased to extreme counterclockwise position by a spring 638. As shown in Figs. 1, 2, and l0, shaft 6I1 to which printing bail584 is secured also has xed thereto a spacing bail 636. lThe free end of bail 639 is in alignment with the operating lug 66| carried by escapement pawl 662, and when print hammer slide 556 is moved to the left, as viewed in Figs. l and 4, the reciprocable pin 596 becomes aligned with lug 66| and with 'spacing bail 639. Upon the release of printing bail 584 by latch BIZ (Fig. 5) and during the movement of printing blade 626 through its printing stroke, spacing bail 639 is drawn away from the end of pin 596. Reciprocation of pin 596 to eiect clockwise movement .of escapement pawl 662 is accomplished during that portion of the counterclockwise movement of bail arm 6 I 6 which was previously identified as overtravel beyond the position for latching of bail 584. When pawl 662 is rocked, ratchet wheel 631 escapes for rotation through a distance equal to one character space Y and the tape, which is pressed against roller 632 by pressure roller 633, is advanced by the tape puller drum. Before cam 6|8 is arrested, follower roller 620 drops oi the apex of cam 618, as previously described, and spring 6|4 withdraws bail 639 from engagement with pin 596, thereby permitting spring 591 to retract the pin to normal position and spring 638 to restore pawl 602 to its normal or extreme counterclockwise position.

The spacing mechanism provided in the printer herein described includes mechanism for automatically inserting a space between any two consecutive quotations on a tape. Thus, no tape spacing signal need be transmitted to eect separation of the quotations. This mechanism is shown in Fig. 4 and comprises a cam projection `625 on print hammer slide 556 which engages operating lug 60| of spacing pawl 662 and holds the pawl in clockwise position when slide 556 is latched in its right-hand position, thepawl being released and permitted to rock to counterclockwise position when slide 556 moves to the left. As previously described, one cycle of oscillation of pawl 662 results in the advancement of tape 630 one character space. print hammer slide following the printing of a stock price, and the release of the slidepreparatory to the printing of another quotation relating to the same stock, the pawl 662 is oscillated through one complete cycle, and therefore the tape will be advanced one character space, the advancement being accomplished in two steps. The first step, representing part of one tooth distance on the ratchet wheel 631, occurs following the printing of a-stock price, and the second step, representing the remainder Vof onetooth distance, occurs before the printing of the next quotation on the same tape. During the printing of a quotation, cam projection 625 isclear of pawl 662, so that it does not interfere with the operation of the pawl by pin 596.

A simple modication of cam projection 625 willv permit the apparatus to interpose two chai'- acter spaces between any two quotations on a tape. This `may be accomplished by providingV a cam slope on the left-hand edge as well as on the right-hand edge of cam projection 625, and by relocating it so that it is at the right of pawl projection 66| when slide. 556 is at extreme right, and is at the left when slide 556 is at extreme left. With this arrangement, cam projection 625 operates and releases pawl 662 upon being re.- tracted, whereby the tape 630 is caused by roller 632 to advance one character step, and Valso operates and releases pawl 602 upon movement to effective position preparatory to printing, whereby the tape is advanced another character step.

The tape puller drums 64I are rotatably4 mounted upon hub sleeves 642 carried by shaft 643. Continuous rotation is imparted to shaft 643 from type wheel shaft 466 through gear 656 carried by type wheel shaft 466 (Fig. 3), gears |655 and 658 carried by an intermediate shaft 651, and gear 659 carried by shaft 643 (Fig. 1). 64I is capable of rotation withrespect to hub sleeve 642 and the drum and sleeve -are both normally stationary while shaft 643 by which they are supported rotates continuously. One end of a flat coiled spring 644 is' secured to the inner annular surface of drum 64I, and the other end is secured to hub sleeve 642. The Vhub sleeve 642 has secured thereto a check ratchet wheel 646 which is checked against counterclcckwise rotation by spring biased check pawl 641. Hub sleeve 642 also has secured thereto a disc 648 on which is pivotally mounted a spring winding pawl 649 engagement with drum 64| by pressure roller 654,Y

carried by spring biased pressure roller arm 656. As drum 64| rotates clockwise in advancing the tape, it advances its pin 652 until the pin is moved Y out of engagement with the tail cam of pawl 649,

which is-thus urged by its spring 65| into eni gagement with continuously drivenratchet 653.

By the retraction of the Drum Rotation is thus imparted from ratchet 653 through pawl SL39, disc E48, and hub sleeve 642 to rewind spring E44. During this rewinding, check ratchet B46 advances tooth-by-tooth with respect to check pawl B41 and holds hub sleeve 52 against reverse rotation upon the disengagement of pawl 55S from ratchet E53. The rewinding of spring 644 is terminated when the tail cam of pawl S49 overtakes and engages drum pin 552. The pin engages the cam and withdraws pawl 649 from engagement with ratchet 653, whereupon the clockwise rotation of hub sleeve M2 is arrested. The head of pawl 649 is provided with a iinger 651, the end of which is disposed in close proximity to the inner annular surface of drum 64| when pawl 6!! is held out of engagement with ratchet 553 by pin 652. Finger 657 blocks the path of pin 652 whether pawl 54S is engaged with or disengaged from ratchet 653 and assures engagement of the pawl with the ratchet as well as prevents unwinding of spring tilt by limiting the amount of clockwise rotation of drum 54S relative to hub sleeve B42.

Since the driving torque is applied to drum 64I solely through spring 'l-i4, it will be apparent that there is no restraint upon counterclockwise rotation of the drum and, therefore, that the tape may be retracted, if desired, without necessitating slipping of the tape with respect to drum 6ft i. Use is made of this feature of the present invention by providing means for effecting a retraction of the tape prior to the printing of a stock quotation and permitting the tape to advance the distance that it was retracted, following the printing of the quotation. The necessary concentration of certain elements at the printing point, such as, the printing bail, ink rib-bon, and type wheel, may cause the last character or last few characters to be obscured by elements of the printer and to become visible only after the tape has been advanced several character spaces. When the printed characters are to be projected upon a viewing screen, a greater number of the most recently printed characters on the tape may be outside he eld of the optical system, due to the presence of structural elements of the printer at the printing point. The advancement of the tape a sufcient distance to bring the last character printed into position to be observed directly may not be suflcient to bring it into the field of the projecting system. Merely to advance the tape several character spaces following the printing of each quotation has certain disadvantages among which is the relatively wide blank space that appears between quotations on the tape with the result that only a small number of quotations may occupy positions in the projecting held at one time, the wide spaces between quotations on a tape being entirely wasted. To overcome these disadvantages, the present invention has been provided with means for for-ming a loop in the tape between the supply roll and the printing position prior to the printing of a quotation, the loop being formed by moving the tape backward against the torque supplied by spring tali to the tape feed drum SM, the tape between the point of formation of the loop and the supply roll being held stationary by the tape feed controlling roller 632.

Referring particularly to Fig. 4, it will be observed that print hammer slide '556 has been provided with a leftwardly extending arm 65| at the free end of which is a roller 662. The length of arm i is such that when the slides 55B are held in their eXtreme right-hand positions, as

' roller 34.

viewed in Fig. 4, the tape will be permitted to occupy an approximately straight path between tape feeding control rollers 632 and idler rollers S34. However, when a print ham-mer slide 56 is released for leftward movement by the tripping of its latch Effi by a selected slide bar 5.5i, the roller 52 will be moved leftwardly and will increase the length of the path between the point of engagement of the tape with rollers 632 and $33 and the point of its engagement with idler The tape required to increase the length of the path will be supplied by rightward movement of the tape past the printing position, as viewed in Fig. 4, tape feed drum @Iii rotating counterclockwise as the tape is retracted. Thus, the most recently printed quotation on the tape will be moved back toward the printing position, thereby reducing to a predetermined low amount the blank tape intervening adjacent quotations. Printing of the figures of the'quotation may then proceed in the normal manner, the tape being advanced one character space for each character printed, by the tape feed controlling roller E532. After the last character of the quotation has been printed, and upon the next clockwisey movement of bail 236i to its latched position, the print hammer slide '556, which has been selected, will be restored to its eXtreme right-hand position and roller S62 will be retracted to permit the tape to assume an approximately straight path between rollers 532 and 6316. The reduction in the length of the path between these two points will result in slack tape which will be taken up by tape feed drum 54H, thus advancing the last quotation printed from the printing position by the distance that the path is reduced. In order that the retraction of the tape, which causes counterclockwise rotation of drum Gill, shall not draw pin 652 olf the counterclockwise end of the tail cam of pawl whereby the pawl would escape from control by the pin, the tail cam should be of sufficient length to accommodate retraction of the type while maintaining pawl tfi disengaged from ratchet 653.

An ink ribbon supporting and feeding mechanism is provided for passing an ink ribbon, such as is used on typewriters and various forms of printing telegraph apparatus, between the tapes 639 and the print hammer heads 5% when the latter are moved into printing position. The ribbon spool supporting and driving mechanism is similar to that shown in copcnding application Serial No. 77,796, filed May 4, 1936, by Albert H.'

Reiber. As shown in Figs. l, 2, and 4, a ribbon feed mechanism supporting plate 565 is mounted above the primary selector mechanism and is provided with spindles 667 upon which ribbon spools 668 are adapted to be mounted. Each of the spindles SS has secured thereto a ribbon feed ratchet 66S, as shown in Fig. 2. A ratchet feed pawl (not shown) is provided in accordance with the disclosure of copending application Serial No. 77,796 for imparting rotation alternatively to either of the spools 5&3 and, in the present adaptation of the apparatus, the pawl is operated by a link 61| which is pivoted to a lever arm 672 secured to shaft 6H which carries printing bail 584 and tape spacing bail 639. Upon each operation of printing bail 584, clockwise rotation is imparted to shaft SVI by the printing spring Gili and counterclockwise rotation is then imparted to the shaft by restoring cam SIB. Link 57i is then moved endwise and is retracted to effect rotation of whichever of the ratchets 665 the ribbon feeding pawl engages.

From the left-hand of the spools 668, ink ribbon 513 passes behind the ribbon guide 614, and around the obliquely cut right-hand end of the guide E574, whereby the path of the ribbon is changed from horizontal to vertical. The ribbon extends upwardly past all of the tapes 53) and across a, horizontally disposed guide mounted above the uppermost of the type wheels by which the ribbon is directed rearwardly of the printer. From this point, the ribbon extends downwardly behind all of the type wheels to a point below the lowermost of the type wheels where there is located a guide similar to the guide 614 for changing the direction of travel of the ribbon from vertical to horizontal. The ribbon is then brought forwardly to the right of the printing position, being guided by means of pins E15, and is engaged with the right-hand spool 558. By virtue of the provision of two ratchets 565, the direction of travel of the tape may be reversed. Thus, at times the ribbon 6'13 may pass upwardly in front of the tapes and at other times may pass downwardly, being alternately transferred from the right-hand to the left-hand spool and from the left-hand to the right-hand spool.

The multiple tape printer, hereinbefore described, is shown in all figures in the normal or idle condition with the single exception of print hammer slide restoring bail 55|. IThis bail is not restored to eXtreme clockwise position as an incident to the printing of a stock quotation, but remains in its extreme counterclockwise position, permitting a selected print hammer slide 55E to remain in its extreme left-hand position, as viewed in Fig. 4, until the reception of the neXt signal combination transmitted, which would ordinarily be the signal combination relating to the rst stock designating letters of the next stock quotation.

Upon the reception of the first code combination representing a designating letter of the stock for which a quotation is to be printed, the sword levers El are set according to the code combination, the transfer levers are unlocked and are set in correspondence with the received code combination by the transfer bail, which also rocks the T-lever 452 in clockwise direction, due to the fact that the code combination represents a letter and the impulse which distinguishes between letters and figures is of spacing condition. The T-lever 452 is not provided with a locking extension to be locked by the bail which locks transfer levers 426, for the reason that it performs the functions. for which it is provided merely by rocking to its clockwise or counterclockwise position, and it is not necessary and may not be desirable to lock it in those positions. The lT-lever operates pawl lever 457 to effect the rotation of ratchet wheel 462 and shaft 463 one step. The uppermost of the reciprocable bars 413 is thereby conditioned for operation by bail 485.

In timed relation to the unlocking of transfer levers 425 and the setting of discs 446 and bars 449, reciprocable bar M3 is operated to effect the restoration of bail 56| to latched position, whereby the previously selected print hammer slide 556 and all of the other slides 555 as well are retracted to eXtreme right-hand position, as viewed in Fig. 4 thereby; to operate bail 53| to disengage all of the latches 521 from the transfer bars 55| to permit those bars to drop to their lowermost position; and to operate bail 492 to effect the setting of storage bars 55| in accordance with the setting of bars 449 through the agencyoftrans.-

fer bell cranks 5G? carried by bail 55S. During this time, all ofthe selectable pins EQ2 are blocked from being selected by special blocking disc 441 whichis latched in extreme clockwise position by latch 56,3, which is pivoted on an arm met carried by printing bail shaft l'l and which is, Y

therefore, operated to restore disc 44? to blocking relation to selectable pins 52 following each printing operation. llShus, none of the pins 592 can move into selected position during the reception of stoel; designating letter combinations ond and third positions, whereby first the bar.

ll'l'tl and then the bar file will be actuated by bail 486 to effect the operation of bail i973 and 484 to store in bars 562 `and the successive selective conditions of barsA 449.

If the stock designation should consist of only one letter or of two letters, thebars 592 and 563, or the bars 5i3, respectively, will not be set but will remain in their lowermost positions, to which they were restored by their springs upon the operation of bail 53| in connection with the 4transfer of the rst received code combination.

If any stock designation should contain more than three letters, or if message material such as news bulletins should be received bythe selector, the letter codes in excess of three will have no effect on the signal storage mechanism. They will merely attempt to step ratchet 462, and as the ratchet has four notches in addition to that which is engaged by pawl 459 in the rest position of the ratchet, as shown in Fig. 1, it can be stepped only until cam 469 has been carried one step beyond its effective position.

Following the last letter of the stock designation, whether the designation has consisted of one, two, or three letters, the signal combination representing the first gure of the price quotation will be received. In this signal combination, the impulse which determines that it pertains to a figure will be of marking nature, and the T-lever 452' will be rocked in counterclockwise direction. This determines that the last of the letters of the stock designation has already been received and no idle interval, representing the time for setting the storage bars 552 and 553, need be interposed between the last letter code of a stock designation consisting of less than three letters and the first figure code of the price.

The counterclockwise rocking oi T-lever 52 causes pawls 459 and t to be stripped from engagement with ratchet 352 which permits shaft 4&3 to return to normal position. Bell crank 579 Y is rocked counterclociwise as holding pawl 464` is disengaged from ratchet e232, the rocking of bell crank 5N resulting in therelease of printing hammer slide restoring bail 55E andthe simultaneous release of one of the latches holding the special blocking disc 44? in blocking position withV respect to selectable pins 5d?. As bail 55| rocks to counterclockwise position, it takes up the lost motion afforded by slot 558, and thus becomes closely coupled to bail 55d for subsequent restoration to extreme clockwise position. Thus, one of the print hammer slides 555, corresponding to the slide bar 5.5i, which had been released as a result of the setting of storage bars 5m, 552, and 5%3 according toY the code combinations repre senting a stock combination, becomes unlatched and is moved by its spring 559 to present its print hammer head 59o in printing position. This movement causes loop forming roller to2 to form a loop in the tape upon which the quotation is to be printed, and the tape is thereby retracted to reduce the blank space between the last printed quotation and the printing position.

At the end of the counterclockwise travel of bail Sl, secondary latch 585 for blocking disc 134? is released and this latch will remain released until bail 55! is restored to extreme clockwise position, which operation will occur in connection with the reception of the code combination representing the first letter of the neXt stock quotation. Upon the release of disc @47 all of the selectable pins 592 are unblocked and the pin corresponding to the code combination of the first figure of the price moves into the path of printing control lever Stil and rocks that lever to efeot the release of printing bail latch H2, whereupon the bail blade 25 strikes the print hammer head 594 which is presented in its path and causes the figure corresponding to the selected pin 592 to be impressed upon the tape by the continuously rotatable type Wheel. Upon the restoration of printing bail 53d to normal position, spacing ratchet escapement S22 is operated to permit the tape to be advanced one step and primary latch 533 for blocking disc lil? is re-engaged with the disc controlling lever 45t is actuated to restore the disc to blocking relation to selectable pins 592.

The code combination representing the next figure in the price also contains a marking impulse indicating that the code combination pertains to a figure, which again causes bell crank 458 to be rocked in clockwise direction. Pawls 559 and iSd are again disengaged from ratchet 4t2. but since this ratchet has already returned to normal position the operation is idle. Lever 57: is operated along with holding pay/l litt, as before, but this operation is not idle, the latch 58S being thereby again disengaged from blocking disc controlling lever del. Latch 33 is released and disc Llll is rocked to its extreme counterclockwise position, thus permitting a selectable pin 5.512 to move into the path of the type Wheel shaft arm, whereby the next figure of the stock quotation price is printed. The type wheels may be provided with fractions and any marks of punctuation and special characters ordinarily used with or as part of stock quotation prices. During the printing of the several gures of the stock price, the code 'bars lfl are set in accordance with the setting of the code discs Mt, but since ratchet @.52 is not operated in response to signal combinations containing an impulse pertaining to the selection of gures, the transfer bails il, El, and 51d are not operated.

By means of the apparatus hereinbefore described, quotations from selected stocks may be printed upon individual tapes identied with the stocks so that the stock designation letters are not printed but are used for selecting the tape kupon which the quotation is to be printed. A much larger number of quotations may thus be displayed or projected than there could be if the stock designation letters accompanied each quotation on the tape. Furthermore, the latest quotation With reference to any stock is moved out into position to be observed or projected as soon as a code combination in which the sixth pulse is of spacing nature has been received, such a code combination causing the stock slide last se- 22 lected to be retracted. When a price is to be printed upon any tape, the tape is retracted so that the quotation is printed in proximity to the next preceding quotation, thus further increasing the number of quotations that may be applied to a given length of tape.

The printer hereinbefore described if desired, be employed directly as a quotation board, by printing on relatively wide tapes with suioiently large characters to enable them to be read at distances from which quotation boards may ordinarily be observed. This requires considerably larger type Wheels than those employed in ordinary type Wheel telegraph printers. 'The fact that the type Wheels of the printer according to the present invention are rotated continuously renders the printer particularly adapted to the use of large type wheels because the inertia eiects which would interfere with the arrestznent of all of the ype Wheels for each printing operation are avoided.

A modified form of tape retracting and releasing mechanism is shown in Fig. le, other elements of the printer Which have already been identilied in the foregoing description being designated by the same reference numerals. In the modified form of tape controlling mechanism, print hammer slides 55% are not provided with tape loop forming rollers as in the previously described apparatus. Additional fixedly located idler rollers are provided, however, there being two designated by the reference numeral till to be engaged by the right-hand face of the tape as it passes from the tape feed roller that face being the front of the tape, and two rollers 682 to be engaged by the sarna face of the tape just in advance of the point of engagement of tape G30 with the tape puller drum till.

A loop forming device vvhich comprises roller supporting platforms 5523 and :i joined by a connecting bar which must be small as possible and as close to the possible to avoid interference with a light beam when a projecting system is used with the printer is supported for endwise movement adjacent to each tape. Platform 533 supports loop forming rollers 687. The rollers 558i' are so positioned with respect to the rollers ESS that ther,7 move through the plane dened by the rollers till as platform @t3 is moved rightwardly. Similarly, platform Sll is provided with rollers 33 so positioned With reference to rollers that they may move through the plane defined by the rolers 582 when platform is moved to the right. Rollers 68? and 538 engage the rear surface of the tape and the rollers S83 are disposed a substantial distance to the left of the rollers tei?. so that the tape follows a tortuous rollers 838 and S82 alternately to reach tape puller drum 613i. Thus, the rollers form loops of substantial dimensions in the tape beyond the printing point.

When the tape loop controlling device which comprises platforms 33 an M and co @Gia gradually reduced in size until left- 684 engages stop TQ3. As rollers d are ca rightvvardly and the loops formed thereby are diminished, the rollers f' pass through the plane defined by the axes of rollers and continue rightwardly thereof to forni loops in the tape at the right-hand end of the tape loop controlling device. The transference of tape loops from the left-hand end to the right-hand end of the tape 23 loop controlling device is accompanied by movement rightwardly past the printing position of a section of tape which had previously moved leftwardly past that position. Thus, the retraction of the tape to permit the printing of a stock quotation price in close proximity to the previously printed price which had been drawn out into viewing or projecting position and the drawing out of the printed quotation into printing or viewing position following the printing operation results solely from the transference of slack accumulated in the form of loops from one side of the printing position to the other Without necessitating movement of the tape past the point of engagement with tape feed controlling roller or tape advancing drum Scl. Since four passes of tape form the loops around rollers G82 and i338, the tape loop forming device need be moved only one-fourth of the distance that tape E335 is to be retracted or advanced by the transference of loops from one side of the printing position to the other.

For moving the tape loop device to the right, as Viewed in Fig. 10, to retract the tape toward the printing position, there has been provided a lever 69! pivcted at 5:3@2 and carrying a pin S93 which is disposed in a slot 6&6 in platform 5&3. Lever 59 is provided with a cam follower projection Sgt* engageable with a cam 691 carried by a shaft ESS- and driven therefrom through a friction clutch. A tension spring @SS biases lever 691 in clockwise direction to maintain engagement of cam follower projection Sgt with cam El. A stop disc it! is provided with shoulders engageacle with the armature 1&2 of an electromagnet '83 when the magnet is deenergized. The circuit of electromagnet 'i133 includes a pair of contacts 'ifl adapted to be closed by a lug 156 carried by print hammer slide 5555 when the print hammer slide moves to its eXtreme left-hand position. Upon energization, electrcmagnet 83 withdraws its armature 192 from blocking engagement with stop disc lei, whereby cam 69? is released for rotation and continues to rotate until the print hammer slide 555 is restored to its extreme right-hand position which, as previously described, occurs upon reception of the first signal combination of, the next stock quotation identification. As cam $9? rotates, it rocks lever Sill to its eXtreme counterclockwise position in opposition to its biasing spring E9e. As lever Esi is rocked to that position, it takes up the lost motion afforded by slot E915 and then moves the tape loop device to its extreme righthand position, slot 59d being wider at its righthand end than at its left-hand end to permit the tape loop device to move in a straight line while lever 6st moves in an arc. Stops 'mi and lil are provided for limiting the movement of the tape loop device in right-hand and left-hand direction respectively. It is important that stop 'l shall be so positioned as to afford the tape loop device sucient movement to the right to permit cam follower projection 556 of lever @Si to clear the cam projection of cam 6.9L

As cam follower projection 6% escapes from each of the projections of cam 691, spring 599 attempts to restore lever Sill to its normal position, However, the clockwise motion of lever till is retarded by a dashpot device 108 which prevents lever @Si from rotating clockwise a sufcient distance to take up the lost motion afforded by slot E94 during the rotation of cam E91 the distance of 180 between its cam pro-jection.Y Lever 139i may move a short distance in clockwise direction between cam projections, but

it will be restored to extreme counterclockwise position immediately and the result will be a slight oscillation of lever 69| which,v however, will not be imparted to the tape loop device which comprises platforms S33 and 684 connected by bar 688.

Fig. l1 shows in schematic form an arrangement for projecting real images of the stock quotations printed on multiple tapes` upon a viewing screen. The multiple tape printed is indicated merely by a diagrammatic showing of a tape supply roll, a tape idler roller, a type wheel, and the tape puller drum. At the rear of the printer are located a lamp 1i l, which is backed by a reflector 'H2 for concentrating and focusing the illumina- 1 tion, and a condenser lens system lift. In front of the printed tapes is located an objective lens 'l' I4 by which the beam of light passing through the tape may be focused upon a plane reflector 'l Hi. Plane reflector 'l I turns the beam of light through and directs it to the rear of a translucent viewing screen 'l l 'i from the front ofwhich the images of quotations printed on the tape of the printer may be observed. The transmission of light through the tape from the rear and the use of a single objective lens and a plane reflector necessitates the printing of figures upon the tape in the position shown in Fig 14, the tape being viewed from the front. With the characters thus printed, the image inversion and rotation taking place at objective lens lli and reector 'l l5 will produce upon viewing screen lll, when viewed fromftlie front of thefscreen, erect real images of the printed characters moving from right to lett as the tape is advanced, which is the actual direction of movement of the tape from the printing ing ribbons and the print hammers are in front of the tapes, the characters will be arranged on the type wheel according to the showing of Fig. 13. It is to be noted that printed characters viewed from the front of the tape, which is the side upon which they are printed, appear in the same relative positions that they do on the type wheel. For this type of image projeotion,-it is desirable to use transparent tape for the printing of the quotations in order that the translucent viewing screen shall be brightly illuminatedY to cause the dark type impressions to stand out distinctly.

It will be apparent from Fig. 11 that the pro-V` jecting systemhereinbefore described is readily other and obliquely to the back wall, and a plui rality of viewing screens parallel to the wall.

In order to keep the projection distance a minimum and in order to employ the most economical optical arrangement, the tapes are divided into groups and short focal-length, inexpensive condenser and projecting lenses are used with each group of tapes, in place of a lesser number Y of long-focus and much more expensive condenser and projecting lenses. The importance of keeping the projection distances low is to reduce f" the total spaceV occupied so that the Aboard can position. Since the type Vwheels are located behind the tapes but the inkbe used Where space is very limited or is expensive. This arrangement is shown in Fig. 12, wherein a single type Wheel shaft lie and single set of each of the storage bars iii, 552, and &33 serves to control the printing upon two or more sets of tapes spaced according to the vertical dimensions of the tape images.

It should be noted that the optical system of each group of tapes inverts, in the image, the order of the tapes in that group, causing the uppermost tape of a group to appear at the bottom of the image of the group upon the screen. Such inversion of individual groups causes te be brought into adjacency on the screen the uppermost tape oi one group and the lowermost tape of the group next below it. This necessitates that if the tape images are to appear on the screen in a particular order, a diiierent order of coding the print hammer selecting slides, having reference to the group inversion, must be established in the printer. Thus, if an alphabetical order of tape images is desired, the order of tapes in the printer must be from bottom to top of the uppermost group, then from bottom to top of the second group, then from bottom to top oi the third group, and similarly down to and including the lowermost group of tapes.
