Potts, Evanston, Ill., assignor, by mesne assignments, to Teletypesetter Corporation, a corporation of Delaware 24 Claims.

The present invention relates to linecasting and composing 'machines and more particularly to selecting mechanisms adapted to be used in conjunction with automatic control units for operating suchmachines. This application is a division of copending application Serial No. 584,387, filed January 2, 1932 which has matured into Patent No. 2,057,652, granted October 13, 1936.

In standard structures of commercially wellknown linecasting and composing machinesthere are provided storage'magazines having pluralities of storage channels each of which receives a predetermined number of slug casting matrices. The length of these channels being limited in accordance with standard construction practices and the matrices being received in said channels endwise, a certain maximum number of said matrices may be supported in each channel. While this number is generally ample for ordinary requirements and in connection with the majority of characters, in their frequency of occurrence it has been found, nevertheless, that in the case of some characters, particularly lower case E and tabulation dots, the requirements of certain lines of composition frequently exceed the supply that may be availed of through the capacity of a single channel of said magazines. More often the available supply of these frequently used matrices is ample for nearly all lines of composition, but since it is possible to have two or three lines of composition assembled at one and the same time in various stages of the slug composing and casting operations, it is more often found that the available supply of certain more frequently used matrices while ample for any single line of composition is inadequate for supplying two or three lines.

To accommodate for such a condition, it has been the practice to allot more than one channel for the storage of such characters and to release the matrices bearing such characters alternately from each of several related channels (usually two) in accordance with a predetermined selective succession. While this problem has been known and has been thus remedied in accordance with manual linecasting and composing machine manipulation, it is somewhat more involved when considered with automatic line composition in accordance with stored signals where alternative channel selection is to be made automatically. The inadequacy of certain frequently employed character matrices that may be obtained from but a single matrix channel is a more pronounced condition when considered in the light of automatic line composition for the greater speed inherent thereto tends to maintain, at nearly all times, several composed lines of matrices in different stages of the composing and casting cycle. This requires a larger available supply of matrices, particularly of those classes whose natural or special frequency of occurrence is extraordinarily greater.

It is accordingly an object of the present invention to provide a simple, reliable, and efficient apparatus adaptable to automatic line composition to select predetermined characters from a1- ternate ones of several related matric storage channels.

For the sake of brevity, commercially wellknown linecasting and composing machines will bereferred to hereinafter generally as principal machines; the auxiliary mechanisms illustrated and described in the above mentioned parent patent will be referred to as control units, and the essential elements which constitute the present invention will be referred to generally as double E or multi-channel shifting apparatus.

Briefly, the present invention contemplates the provision of a pair of similarly coded selector elements and an additional modified code. bar, the positionment of which is cyclically controlled so as to block the selection of one or another of each of said pairs of selectable elements whereby but a predetermined one of the pair may respond to their common selecting signal and where the shifting from one channel to the other is accomplished periodically so as to afford access to both storage channels and in this way to a larger number of available matrices.

It is proposed, in accordance with the preferred embodiment of this invention, to control periodically the shifting of the aforementioned apparatus cyclically in accordance with each line of composition and under associative control of the assembly elevator. Towards this end the shifting apparatus is being illustrated and described herewith in association with an operating shaft which initiates the performance of the assembly elevator. It will be understood, of course, that this interrelation is arbitrary and is suggested by way of example only, and that feasibly the shifting may be accomplished under the control of any other periodically operating organ that may be incorporated in the control unit.

Fora more comprehensive understanding of the present invention, reference should be had to" detailed specification in which like reference characters denote similar parts throughout.

The reference characters II indicate generally a set of matrix release reeds, which, as illustrated in Fig. 2, symbolizes the composing mechanism of the principal machine. These reeds are individually actuated by associated weight bars l2 (Fig. 4), which are selectively conditioned by horizontally moving selectable elements l3, one of which is associated with each bar I 2. At their left extremity, as viewed in Fig. 4, the elements l3 are notched to cooperate with variously coded notches and lugs that are provided in a set of code bars M. Upon each conditioning of the several code bars Hi there is presented a transverse row of notches which affords a clearance to one of the elements I3 and permits the latter element to respond to the urge of an individual spring I5 associated therewith. The code bars M are variously placed or conditioned through the instrumentality of transfer elements which in turn receive their setting from a set of feelers located in the record reader 24. After each setting, the selected one of the elements I3 is restored by the cyclic operation of a return bail 2!], the operation of which is suitably timed as described in the parent patent referred to above. Bail 20 is provided with a longitudinally extending lip with which it engages the shoulder ill of any of the elements or bars l3 when the latter is found in selective condition. When one of the selectable elements I3 is selectively conditioned, it displaces the bar I2 associated with it, presenting the latter into a position as illustrated in dotted lines in this figure, whence it may be engaged by a periodically reciprocating bail member I6 which imparts a vertical thrust thereto. Through the instrumentality of bar I2, this motion is communicated to the release reed ll, thereby causing the release of an associated matrix supported in a storage magazine 11.

Matrix storage magazine I! is provided with a plurality of channels 3 within each of which there resides, in endwise alignment, a plurality of matrices of a certain character. In accordance with the well-known system of matrix distributors, these matrices are released and assembled for line composition after which they are transferred to the slug casting chamber. Thence they are elevated to a distributing mechanism where, in accordance with certain notched characteristics peculiar to each matrix, they are restored to the channel from which they originate.

As indicated above, it has been found, during the composition of certain matter particularly in the case of extra width columns, that the frequency of occurrence of certain alphabetical characters such as, for example, the lower case E and in the case of other characters such as periods, etc., may exhaust the supply of matrices that can be availed of by the capacity of a single channel l8. To supply such frequently occuring characters, it has been proposed to allot several channels l8 for their accommodation and in this manner to increase the storage capacity for those certain matrices only, while maintaining for others the normal available supply afforded by but a single storage channel. The channels l8 are formed in substantially parallel alignment in the matrix magazine ill and in accordance with the versatility afforded as a feature of the present invention, each related pair of channels I8 may be located as remotely from each other as desired.

In explaining the application of the present invention, but a single matrix character, the lower case E, will be illustrated and described hereinafter, it being understood that the accommodation for other characters or for pluralities of characters may be obtained by enlargement or extension of the principles to be hereinafter described.

Referring now to Figs. 1, 2, and 3, it will be noted that the operating mechanism of the control unit is driven by means of a pulley belt I9 from the intermediate drive shaft of the principal machine. Power transmitted through belt I9 is communicated to a pulley 2i and from there through a pair of gears 22 to a driven shaft 23. As will be noted by reference to the parent disclosure, the essential functions of the driven shaft'23 reside in its manipulation of the record reader mechanism 24. Through another gear pair 25 there is driven an auxiliary operating shaft 26, the essential function of which resides in its manipulation of the assembling elevator. It is in association with this latter shaft that the present invention will be illustrated in accordance with a preferred embodiment.

Shaft 26, through worm 2'! drives a stud shaft 28 (Figs. 2, 5, and 6) by its engagement with a worm wheel 29. Mounted on shaft 28 is a clutch 3! having a driven portion 33 which is normally withheld from engagement with its driving portion 32 through the cooperation between a lug 34 integrally formed with it (Fig. 4) which encounters alternately each of a pair of disengagement levers 35 and 36. Each lever 35 and 36 is provided with a horizontally extending section that is placed tangentially with respect to the driven member 33 and contains an opening (see Fig. 5) one side of which is beveled in a direction such that when the lug 34 is received thereinto, the latter member together with its integrally formed main portion, the driven section 33 is cammed away from the driving section 32. Through clutch 3i motion is imparted from shaft 28 to a sleeve 31, which carries a cam 38 for operating the elevator raising mechanism and a spur gear 39 best indicated in Figs. 3, 4, and 5. The elevator operating cam 38 functions through a bell crank segment 4 I, forcing a thrust rod, generally indicated 42, which is comprised of a dash pot 43 and a compression spring 44 to rock bell crank lever 45, pivoted at 46, one arm ll of which is connected to the elevator push rod 48. The operation of the elevator lifting mechanism and its control is more fully described and explained in the parent patent referred to above.

The spur gear 39 which is also secured to sleeve 31, cooperates with a driven gear 49 that is carried upon a stub shaft The ratio between spur gear 39 and driven gear 49 is 1 to 2 in the instant adaptation, though, as may be discerned from the following description, this ratio may vary in accordance with the number of alternative positions to be assumed by a selector bar 52 which in turn will correspond to the number of matrix storage channels to be served in the selection. In the instant case, but two channels are thus served, so that the gear ratio mentioned above is accordingly 1 to 2. Thus While shaft 28 is making one revolution, shaft 5| will make but one-half revolution, or, in terms of elevator operations, for each operation of the elevator manifest by one revolution of shaft 28, shaft 5| will describe a half revolution, assuming either of two alternative positions, one of which is illustrated in Fig. 6. During this condition, a crank 53 carried by the foremost end portion of shaft 5| remains with its driving pin 54 in the upper position. During its alternative condition, which is not illustrated, the pin 54 is in an opposite position 180 therefrom. Pin 54 travelling in a slot 55 formed in one arm 55 of a bell crank member 51 reciprocates the latter during its alternative presentment, causing the other arm 58 of bell crank 51 to assume either of two corresponding positions, one of which is illustrated in Fig, 6. This motion is imparted through the disc and socket connection 59 to the special code or selector bar 52.

Bar 52 lies parallelly with and functions in a generally similar manner to the standard code bar selectors l4. It differs in this respect, however, from the other code bars; where the general class of code bars [4 are variously provided with notches and projections throughout their entire length, which notches and projections cooperate in the selection of any of the selectable bars i3; bar 52 is provided with but a few isolated projections indicated 5| that cooperate in the selection of but those certain selectable bars [3 which function to condition and cause to be operated the release reeds ll of plural channel contained matrices; in the instant case, the lower case E character matrices. Where a particular character is provided with two channels, bar 52 will accordingly be provided with two projections 6| serving in this selection, and where another character is likewise provided with two channels, bar 52 will be provided with two additional projections 6| serving its alternativeselectable bars l3 in a similar manner. Since for each selection of the several bars i4 but one class of character selectable bars I3 may be selected, bar 52 functions in a secondary capacity to determine which of two associated character bars l3 will be the one to respond in accordance with the particular selection.

During its normal condition, shaft 28 is disposed in the position illustrated in Figs. 3 and 6 with its projection 34 residing in the opening of lever 35. Upon the selection of the elevator selector bar 62, Fig. 3, a link 53 is pulled upwardly, and through its connection at 54 with lever 35, causes the latter likewise to be pulled upwardly or rotated about pivot 65. This performance may also be obtained manually by depressing the projecting portion 65 which protrudes from the ,iramework, generally indicated 61 in Fig. 6. In this manner the driven portion 33 is released and is permitted to engage the constantly rotating driving portion 32. Following this, the driven portion 33 describes a half revolution whence projection 34 comes into engagement with the bevelled opening of lever 36 where, as in the case of lever 35 and in a similar manner, it is again withdrawn, separating the elements of clutch 3|v and momentarily arresting shaft 28. Coincident with this performancathe elevator is raised by cam 38 to its upper level where the assembled matrices may be removed by the delivery slide for transmission in a manner Well known in the art.

As a result of the movement of the line delivery slide, an arm 63 associated with it is permitted to reciprocate through a limited are from its normal position, illustrated in Fig. l, first in a counterclockwise direction, then back again in a clockwise direction. Arm 53 and itsperformance being characteristically well known in the art of commercial types of lineoasting machines, it will be understood that the movement thereof permits a corresponding movement in a clutch release bail 59, pivoted at H, which bail through link 12, also illustrated in Figs 2, 3, and 6, controls the release of clutch 3| in its second half revolution.

The clutch release bail 59 is spring-urged in a counter-clockwise direction and is maintained in its clockwise extremity by the tangency of the delivery slide arm 58, see Fig. 1. In its first movement in a counterclockwise direction, bail 59 thrusts rod 12 rightwardly, as viewed in Figs. 2, 3, and 6, causing an intermediate lever 11 to be rocked in a counterclockwise direction about its pivot stud l8 and thrusting a connecting rod i9 leftwardly. This trips bell crank lever 36 through the engagement of a pawl 13 carried by rod 19 and thereby releases the driven portion 33 of clutch 3!, allowing the latter to complete the second half of its revolution. Thepurpose of conditioning the consummation of the cycle of shaft 28 upon the proper operation of the elevator is to prevent the return of the matrix assembling block to its composing level in case of an uncompleted delivery, in which event the load of matrices would still remain in the assembling block. Upon the return of the delivery slide arm 68, bail lever 53 is rotated clockwise, imparting a leftward motion to connecting rod 12, a counterclockwise motion to lever l1, and a rightward motion to connecting rod 19. This permits pawl 13 to again engage the depending projection 14 of bell crank lever 35 in contemplation of a succeeding operation; The tripping of lever 35 as in the case of lever. 34 may also be manually executed by depressing the projecting portion '55 which protrudes from the framework 67. It should be noted that the second half revolution of shaft 23 being responsive to the release of the delivery slide arm 63 is conditioned thereby upon the successful operation of the elevator without which the delivery slide arm 53 may otherwise not be permitted to enter upon its cycle of operation, so that pawl 73 thereby is conditioned also through its engagement with projection "M of lever 35.

Upon a successful operation of the elevator, the shaft 28 describes a complete revolution of 360, imparting a half revolution of 180 to shaft 55 and causing the latter, through its articulation with special bar 52, to be moved from one of its positions to the other, depending upon the preceding or last operated condition thereof. Thus, in accordance with the particular embodiment, bar 52 functions to condition for selection one of two alternatively selectable code bars l3 during the composition of one line and to condition the other bar l3 during the composition of a consecutive line. The projections 6| which are provided with bar 52 correspond one with each of the selectable elements or bars I3 to be served. Accordingly there are as many pairs of projections 6| as there are pairs of bars l3, and the several pairs 6| are so arranged that upon one placement of the bar 52, certain ones of each pair of projections 61 are presented so as to block the selection of their associated elements l3 while the other ones of. the pairs of projections 6| present a clearance and permit the selection of their associated elements l3, but upon the alternative placement of the bar 52, the corresponding blocking and clearance conditions are reversed. In this way bar 52 by its relative placement is able to condition for selective operation each element l3 of a pair or ones of several pairs, the ultimate selection of the elements depending of course upon the placement of the standard selector bars 54 in accordance with code signals.

It should be understood that if the frequency of alternative channel selection is inadequate, in accordance with an arrangement for shifting during successive lines of composition, the present invention may be associated with an operating organ of the control unit other than shaft 28, the cycle of operation of which is more frequent in occurrence, or, if preferred, a special operating shaft deriving its power from any suitable source may be supplied for actuating the elements which in the instant case have been associated with the elevator operating shaft 28.

While the present invention has been explained and described with reference to a specific embodiment thereof, it should be understood that numerous changes and modifications may be made without departing from the spirit or scope thereof. It is therefore intended not to be limited to any of the details of the foregoing description nor to the specific illustrations of. the accompanying drawings, but to be permitted, instead, a latitude of interpretation as indicated by the hereinafter appended claims.
