Larson, Chicago, Ill., assignor to Teletype Corporation, Chicago, 111., a corporation of Delaware Application January 8, 1934, Serial No. 705,646 Renewed March 28, 1935 19 Claims.

The present invention relates to linecasting and composing machines and more particularly to improvements in automatic control mechanisms for the operation thereof.

This application embodies an improvement relating to the subject matter concerned in copending applications Serial Nos. 584,387 and 721,657 filed January 2, 1932 and April 21, 1934, respectively.

Linecasting and composing machines of the commercially well-known types are frequently provided with a plurality of matrix storage magazines sometimes located one above the other in vertical alignment and at other times one along side the other in horizontal alignment. The purpose in providing more than one such magazine is to afford increased variety or selectivity under the control of a single operating unit, or, in a more limited sense, under control of a single set of release reeds. Thus with a given number of matrix release reeds which are equivalent in number to the number of classes of matrices in one storage magazine and by providing means for shifting said release reeds collectively they may be made to serve an additional one or ones of a plurality of matrix storage magazines, and by having associated with each magazine a certain class of matrices, the total number of selections is thereby materially increased.

The shifting of a common set of release reeds to associate them with each of a plurality of storage magazines involves the moving of several massive operating members whose response is inherently of a slow nature as compared with the release operations of the individual matrix release reeds and escapement mechanisms. Accordingly, where automatic Lmits are employed for the control and operation of linecasting and composing machines and where, in addition, it is desired to employ the automatic means for shifting the release reeds between each of a plurality of magazines, it is necessary that a proper time delay interval precede the consummation of each shift operation and that the record reading apparatus which is responsive to stored signals be momentarily arrested in order to allow a sufiicient amount of time for previously released matrices to be properly assembled and for preventing the idle operation of the sensing apparatus. It is also desirable to arrest the progress of the control form or perforated tape during the comsummation of the shift operation in order that the reception of subsequent matrix release signals may be suspended until the release reeds have been completely shifted and are brought into alignment with the newly selected magazine escapements.

The main object of the present invention is the set of release reeds between each of several matrix storage magazines under the control of stored signals. 7

A further object of the invention is the provision of means for arresting the signal sensing mechanism during the reed shifting interval and for interposing a variable time delay element that is effective during the aforedescribed shift operation to suspend operation of the line composing control mechanism.

In order to: describe the present invention, a preferred embodiment thereof has been illustrated in the accompanying drawings and is particularly described in the following specification. This adaptation of the present invention is designed to be applied to mechanisms such as that disclosed in United States copending applications serially numbered 600,606, filed March 23, 1932, and 704,467, filed December 29, 1933. In accordance with the provisions thereof, a record reader mechanism is employed having a constantly rotating control shaft that is operative to periodically withdraw and permit to be returned a set of tape sensing levers. The same shaft is also operative upon a signal transfer mechanism and in accordance with the variable position of the several sensing levers causes the transfer of a set of code signals to a corresponding set of code selector bars. The position of the several selector bars then affords a selective clearance to one of a plurality of individual elements which thereupon is permitted to be moved into effective position where, under the influence of a common actuator, it receives an actuating motion with which it initiates the particular performance for which it is delegated.

It is contemplated, in accordance with the present adaptation, to control the shifting of a set of common release reeds between the escapement mechanisms of each of a pair of magazines located one above the other and to be referred to hereinafter as the main and the auxiliary matrix magazines. The release reeds are carried in a carriage or cradle member that is capable of being reciprocated laterally so as to present an adjacent portion of the release reeds in operative alignment with one or another of a corresponding set of escapement mechanisms. The shifting of the carriage is effected through the agency of a series of levers and bell cranks which are under the control of a pair of symmetrically similar and opposite actuating levers each of which is selectively set into its effective position and tends to perform its shift operation through the medium of a spring element which receives and momentarily stores the shift impulse under relatively instantaneous control to await the more lumbersome or slower response of the magazine shifting linkage.

The pair of spring urged actuating levers are selectively set by a corresponding pair of bars feeler levers.

which in turn are under the control of a pair of pivoted levers that extend into the region of and are controlled by one pair of the plurality of selectable elements which are under the control of record reader mechanisms mentioned above. The arrangement of the levers is such that the selection and operation of one concurrently effects the release of the other.

For a better or more comprehensive understanding of the present invention, reference may be had to the accompanying drawings in which like reference characters designate similar parts throughout and in which Fig. 1 is a perspective view of portions of a tape sensing mechanism and a line composing machine embodying the present invention having certain portions broken away or omitted for the sake of clearness;

Fig. 2 is a side elevational view of the control reed shifting mechanism;

Fig. 3 is a fragmentary elevational view of a portion of the mechanism illustrated in Fig. 2 showing another condition of operation thereof;

Fig. 4 is a transverse sectional view through the record reader mechanism illustrated in Fig. 1, and

Fig. 5 is a transverse sectional view similar to Fig. 4 but illustrating another condition of operation thereof.

In the accompanying drawings the reference character N indicates generally a record reader mechanism which is adapted to receive a continuous web of material l2 fed through the medium of a sprocket Wheel l3 that is carried upon a shaft l4. A ratchet wheel |5 also secured to shaft l4 receives intermittent motion under the impulses imparted to it by a reciprocating pawl I6 pivotally supported upon the extremity of a lever I! which is in turn pivoted upon a stud shaft l8 as better illustrated in Figs. 4 and 5. The lever I! is normally urged in a clockwise direction by a spring l9 and responds thereto until an opposite extremity 2| thereof comes into contact with the end of an adjustment screw 22.

Another lever 23 also pivoted at l8 carries the adjustment screw 22 and is provided at its extremity with a follower roller 24 which engages and follows the periphery of a cam 25 secured to the record reader operating shaft 26, so called because in addition to the feed sprocket cam 25 it carries also two other cams 21 and 28 which together with cam 25 perform all of the functions incident to actuating the several elements which comprise the record reader Cam 21, Fig. 1, engages the follower roller of a bail assembly 29 which, through its bail rod 3|, periodically withdraws the several levers 32 and 33.

The levers 32 are in the present instance six in number and will be referred to hereinafter as They differ in one essential from the lever 33 by being provided with integrally formed arms 34 at the extremity of which are carried the feeler pins 35. Each revolution of the shaft 26 may be considered as the unit operating cycle, at a certain interval in which cam 25 operates to feed the tape l2, during another interval in which cam 21 withdraws the several feeler levers 32 and 33, and during a third interval in which cam 28 operates the transfer mechanism for relaying the signal as it is sensed by the several feeler levers 32 and lever 33. As the feeler pins 35 are permitted to engage the tape l2, certain of them encounter perforations and are permitted to rotate in a counterclockwise direction until the feeler pins 35 protruding through the tape I2 permit the main body portions 32 to assume positions such as that exemplified by the foremost lever in Fig. 5, while certain others of them, failing to encounter such perforations in the tape I2, are thereby withheld from rotating to this extent and assume positions such as indicated by the posterior lever illustrated in Fig. 5. In accordance with the alternative placement of the levers 32 or 33 as thus indicated, their lowermost projections 36 and 31 are brought into registration with either one or the other of a pair of cooperating lugs 38 or 39 of corresponding transfer levers 4|.

The transfer levers 4| are of Y-shaped configuration and correspond in number to the levers 32 and 33. The several transfer levers 4| are loosely pivoted upon a shaft 42 which forms part of a bail structure 43 rotatable about the axis 44. The bail 43 forms part of a bell crank assembly in its relation with the arm 45 which carries the follower roller 46 that in turn constitutes the contact member engaging the actuating cam 28.

Through the impulses received from cam 28, the bell crank assembly 4345 is periodically rocked about shaft 44, thrusting the several Y- shaped transfer levers 4| upwardly and into engagement with their projections 36 or 31 in accordance with which the levers 4| are rocked correspondingly in a clockwise or counterclockwise direction depending upon the condition of their associated levers 32 or 33. Lowermost projections 4'! of Y-shaped levers 4| comprise connection elements through which the levers 4| are articulated to a corresponding set of connecting bars 48 through which the condition transferred by the levers 4| is imparted to a set of code bars 49. The code bars 49 are provided with variously arranged notches 5| and projections 52 such that in accordance with each placement of the several of them an individual transverse alignment of the notches 5| is afforded, permitting a clearance thereby into which may be admitted an adjacent one of a plurality of selectable elements 53.

Elements 53 are constantly spring urged by individual springs 54 and are momentarily permitted, in response to such urge, to seek admission into their respective alignment of notches 5|, but since for each placement of the several code bars 49 there is permitted but a single alignment of notches 5|, only one of the elements 53 may be thus selectively conditioned by admittance thereof into its alignment of notches. Will be fully understood by referring to the copending applications mentioned above, the selective conditioning of any of the elements 53 results in the ultimate performance of a certain function to which the particular element may be delegated. In the interest of explaining the present invention, two of the elements 53 specially indicated 55 and 56 are particularly significant in that they control the performance of the magazine shift mechanism about to be described. In this connection it is noted that among the code bars 49 one is specially indicated 51 and that this bar differs somewhat from the general class of bars 49 by being provided in this case with but two lugs 58 and 59 which normally register belowlthe selectable elements 55 and 56, respective y.

The selection of either of the elements 55 or 55 is obtained upon the reception of either of two associated signals in accordance with a predetermined arrangement. Upon the reception of either of these two signals a certain condition is established peculiar thereto and differing thereby from any of the conditions that are established upon the reception of any other signals as will be indicated. While this special condition will be described as resulting from the reception of but these two indicated special signals, it may be observed that any number of signals may be made to respond with a similar result and that the particular signals have been arbitrarily selected so that, if desired, any other particular signal or signal code may, if preferred, be substituted instead.

The response of the record reader H to either or any of these special signals is similar to the response of the general class of signals up to the point of positioning the several connecting rods 58. Each bar 48 is provided with a notch 6!, Figs. 1, 4, and 5, individual to it and arranged with respect to the other notches 6d of the other bars 48 in a manner such that upon the reception of either or any of the specially delegated signals such as the ones which are to select the elements 55 and 56, the notches El are brought into transverse alignment affording a clearance, as in the case of the notches 5|. In this case, however, there is admitted into the clearance a transversely extending rod 62 which is carried by a bell crank lever having a laterally extending arm 63 and an upwardly and rightwardly extending arm 64. A spring 65 urges the bell crank lever iii-64 in a counterclockwise direction and when the clearance permitted by the alignment of notches GI admits the rod 62 thereinto, the bell crank is rotated about its pivot 66, allowing the upper extremity of arm 64 to move behind the extremity of a downwardly and rightwardly extending projection 51 integrally formed with tape advancing lever I I. The movement of arm 64 behind projection 67 occurs during the instant in which lever H is in its elevated position as illustrated in Fig. 4, preventing the return thereof in response to the urge of spring I!) and causing to be arrested thereby the further progress of tape advancing shaft M and its associated elements.

In addition to this result, the aforedescribed selective movement of bell crank lever 63-64 is manifest in a further result. Normally and before this selection a pin 68 secured to arm E l engages a downwardly projecting pawl 69 and withholds it from operative engagement with a ratchet wheel ll. Pawl 69 is pivotally carried by an associate portion 72 which may be integrally formed with the constantly reciprocating lever 23. Pawl 69 is normally urged in a clockwise direction by a spring 73 so that it receives, at all times, a reciprocal motion under the actuation of lever 23, but until the selective movement of bell crank lever 63-64, the reciprocal motion of pawl 69 is ineffective. After the aforedescribed selection of bell crank lever 63-64, however, when pin 68 is withdrawn, the tooth of pawl 69 is permitted to come into engagement with the periphery of a ratchet wheel H, causing to be imparted to the latter member a counterclockwise movement as viewed in Figs. 1, 4, and 5- 1 The motion imparted by pawl 69 to ratchet wheel H results in a progressive rotation of shaft 14 because of the detent effect of cooperating pawl T5 in association with a secondary ratchet wheel I6, Fig. 1. The rotation of shaft 14 under the stimulus of a ,..cont nues unuia p n 11 carried by ratchet wheel H encounters a sidewardly extending lug iii of a tripolf lever 19 loosely pivoted on shaft 14. When this occurs, the motion of shaft M is imparted to lever 19 which thereupon joins in the movement therewith until a condition is obtained such as that indicated in Fig. 4 when an adjustment screw Bl carried by lever 19 comes into contact with and subsequently moves lever 33 from its counterclockwise position, in which it is normally found, to its clockwise position as indicated in this figure.

Meanwhile, cam 28 continuing to rotate with shaft 26 imparts a reciprocating motion to the bail structure 43 and through it to the several transfer levers 4!. But since the tape I2 is arrested at this time and the several levers 32 and 33 maintained in the same position by the registration of the particular code of signals in a dormant condition, no result or change of conditions is obtained by the reciprocal movement of the I transfer levers 4!. When, however, the special lever 33 is moved leftwardly by the continued rotation of shaft M and the motion imparted to it through lever 79 and screw 8 l, a new condition is established so that upon the succeeding reciprocal movement of the bail structure 43 when the transfer levers 4! are brought into engagement with the several levers 32 and 33, the particular transfer lever coming into engagement with special lever 33 is rotated in a clockwise direction, causing st to be moved its connecting bar '58 rightwardly and thereby withdrawing the special code bar 5? in the same direction.

As the code bar 51 is withdrawn and with it its associated connecting bail 8, rod 82 is cammed out of the alignment of notches El by the displacement of the particular bar 48 associated with code bar 5?. In so doing, bell crank 53-6 5 is rotated clockwise and the foremost portion of arm 64 is withdrawn from blocking projection (if. 4

This frees lever H and permits it to resume tape feeding operations while at the same time pin 68 reengages pawl 69 and cams it away from ratchet wheel I I. Cooperating pawl 15 has integrally formed with it a backing strip 80, Fig. 1, so that as pawl 69 is withdrawn its cooperating pawl 15 is also withdrawn. This frees shaft M which then, in response to a spring 96, is restored to normal position as indicated in Figs. 1 and 5.

The normal position of shaft 14 is determined by the stop position at which an arm Hm, which is angularly adjustable thereon, encounters the stop pin I Hi which is anchored in the supporting structure. Where it is desired to vary the amount of time occupied by the aforedescribed mechanism in effecting a delay, it is but necessary to vary the angular position of arm I08 with respect to shaft 14, or in other words, to vary th number of teeth which intervene the normal or stop position of shaft 74 and the point at which pin 1! encounters the projection 78 of trip-off lever 79.

As was stated before, the signals which started into operation the mechanism under the control of the alignment of notches 5! belong to a class which in the present case is adapted to place into selective condition two of the plurality of selectable elements indioated 55 and 56. Upon the proper alignment of the several code bars 49, in response to the particular signals, a row of notches 5i is brought into alignment for the selective conditioning of either element 55 or element 56, but due to the normal position of the projections 58 or 59 the particular element 55 or 55 is not permitted to enter into the transverse clearance that is afforded by the notches 5| of the remaining code bars 49. This condition prevails during the time in which shaft I4 proceeds to rotate as described above. At the conclusion of this operation when the special lever 33 is displaced and its changed condition is transmitted into a movement of code bar 5'1, the projections 58 and 59 are withdrawn momentarily, permitting the particular one of the elements 55 or 59 to enter into selective condition and to promptly complete the operation for which it is delegated.

In carrying out the functions of the particular invention, elements 55 and 56 cooperate in a reciprocal manner, and are found most conveniently arranged in symmetrically opposite relationship as indicated in Fig. 1, under which condition eement 55 has a downwardly extending projection 92 while element 56 has a similar upwardly extending projection 83. Projections 02 and 83 cooperate with a pair of first class levers 84 and 85 which are pivotally supported in spaced relation with respect to each other upon a vertically extending post 96. For purposes of regulation, levers 94 and 85 are provided with adjustment screws Ill, indicated also in Figs. 2 and 3.

Upon its selective movement either of the levers 55 or 56, is thrust forwardly, as indicated in Fig. 1, rocking its associated lever 84 or 85 in a clockwise direction. In the case of lever 84 this motion is imparted to an associated bar 08 which is confined to limited horizontal motion by the slots 89 and its supporting screws 9 I In the case of lever 85 the motion is imparted to a similar but symmetrically opposite bar 92, Figs. 2 and 3. Bar 92 is similarly provided with slots 89 and supporting screws 9I. As viewed in Fig. 2, the right-hand screws 9| of bars 88 and 89 are secured to a base plate 93, but the left-hand screws 9| are each carried in a sidewarclly extending lever 94 of a T-shaped lever 95 that is centrally pivoted at 96. A sidewardly extending arm 91 of lever 95 is pivotally articulated at 98 to a link 99 which is in turn connected at IOI to a bell crank I02.

The movement of either bar 88 or 92 in response to the selective motion imparted to it which originates with its element 55 or 56 is adapted to move link 99 upwardly or downwardly for the purpose of shifting a common set of release reeds I26 into communicating relation with one or another of a pair of sets of martix escapements I21 and I29, and, in addition, is adapted to release its associated element 88 or 92 from its previously set position. The manner in which this is accomplished may be best perceived by comparing Figs. 2 and 3, supposing a condition existent as illustrated in Fig. 3 in which the mechanism is disposed to render the main magazine in effective condition. The alternative will then be as illustrated in Fig. 2 with the auxiliary magazine in effective condition. To obtain this end, element 84 is selectively operated causing its screw Bl to engage bar 88 and shift the latter member leftwardly. With this, the foremost end I03 of bar 68 is brought into engagement with arm I04 of a three-armed lever I05 that is also pivoted at the pivot screw 96. This causes lever I05 to be rotated in a clockwise direction. In so doing, another arm I06 of lever I05 being connected to a spring I01, the other end of which is secured to an arm I08 of a similar lever I09, causes the stretching of spring I01, and thereby storing the operative impulse, which originated with the selective movement of element 55, within the spring I07. After bar 88 has moved through a predetermined distance and lever I05 has been rotated from the position indicated in Fig. 3 until its approximate position as indicated in Fig. 2, another arm III of lever I05, which is provided with a shouldered tooth II 2, becomes latched behind the projection II3 of a spring loaded pawl II4 pivoted at II5. At about the same time a pin II6 which may be integrally formed with bar 88 and engaging one end of another pawl III similar to but in symmetrically opposite relationship with pawl I I4 rocks the latter member clockwise into the position as indicated in Fig. 2 and thereby releases its hold at projection II 8 of lever I09. When lever I09 is thus freed, it responds to the urge of spring I01 rotating clockwise from the position indicated in Fig. 3 to that indicated in Fig. 2 when its arm IIO encounters a stop pin I20. Levers I05 and I09 are provided in their arms I06 and I08 with coacting screws H9 and I2I arranged in opposite abutting relation and receiving between them the arm 91 of T-shaped lever 95.

Thus when lever I09 is freed by the release of its pawl I I1 and is permitted to assume a position such as that illustrated in Fig. 2, its clockwise motion is imparted through screw IZI to the lever 95, thrusting arm 91 upwardly and accordingly moving link 99 upwardly. This rotates bell crank I02 in a counterclockwise direction about its pivot I22. In so doing, the upstanding arm I23 of bell crank I02 is rocked to the left.

The motion of arm I23 is transmitted through its pin and slot articulation I24 to a cradle structure I25 within which is supported a set of release reeds I26, moving the latter from their previous position in registration with the escapement bars I2! of the main magazine, Figs. 1 and 2, and into registration with another set of escapement bars I28 of the auxiliary magazine.

The released reeds I26 are free to partake of limited vertical movement under the actuation of manual control keylevers or automatic control keylevers as fully explained and illustrated in the copending applications referred to above. This motion by reeds I26 may be communicated to the bars I21 or I28 in accordance with the placement of cradle I25. As illustrated in Fig. l, cradle I25 is disposed to permit the cooperation between reeds I26 and bars I21, whereas in the showing of Fig. 2 the reeds I26 are illustrated in full line position as disposed to register with bars The bars I21 cooperate each with an individual escapement device, generally indicated I29, of an upper storage magazine I3I, referred to as the main magazine, while the bars I28 cooperate with other but similar escapement devices I32 which are associated in corresponding manner with a lower matrix storage magazine I33, referred to as the auxiliary storage magazine. In accordance with its relationship with main magazine I3I or auxiliary magazine I33, the released bars I21 may be referred to as the main release bars, while those indicated I29 as the auxiliary release bars. It may be explained that with the cradle I25 in position to permit the registration of reeds I26 with the main release bars I21, line composition may continue indefinitely with the matrices released from the magazine I3I. In a similar manner with carriage I25 in its alternative condition and reeds I26 in registration with the auxiliary bars I28, line composition may likewise continue indefinitely, depending, of course, upon the character of matrices in each magazine I3I or I33 and upon the desired font or type classification which it may be desired to use.

(III

In'accordance with the foregoing description of the shifting operation, a carriage I25 was described in its transit from main magazine com position to auxiliary magazine composition. The movement in the reverse direction is identically similar in all respects except as to the symmetrically opposite movement of the several elements. In this case bar 56 is selected and is likewise delayed from completing its selective movement by the blocking of projection 59. After the intervention of a predetermined delay interval when bar 57 is withdrawn, element 55 is permitted to assume selective condition and in being moved forwardly, its projection 83 rocks lever 85 in a clockwise direction, thrusting bar 92 left- Wardly as viewed in Figs. 1, 2, and 3. The movement of bar 92 is transmitted to lever III, as in the case of bar 88 and lever I65, until the latching arm of bar I9 comes into engagement with tooth H8 of pawl II'I. Thus the lever I59 moves from a position such as that indicated in Fig. 2 to a new position such as that indicated in Fig. 3.

The continued movement of bar 92 causes its pin IIB to release pawl II' I, freeing lever I5, whereupon spring IG'I urges lever N39 to resume its original position as illustrated in Fig. 3. In so doing, screw II 9 forces arm 97 downwardly, pulling link 99 in the same direction and rocking bell crank I02 clockwise about pivot I22. This shifts cradle I25 from its auxiliary back to its main position.

The shifting of cradle I25 from cooperative relation with the bars I21 and I28 is essentially a slow operation due primarily to the large mass of carriage I25 and its content of release reeds I25. For this reason where it is desired to mix, in a single line of composition, the matrices of main magazine I3I and the auxiliary magazine I33, and where, in accordance with such a purpose, the movement of carriage I25 may be executed in the midst of a single line of composition or even several times during a single line of composition, the foregoing described structure is especially designed to introduce a time delay interval between the instant when a magazine shift signal is received in the tape I2 and the instant at which either element 55 or 56 is selectively operated. This time delay interval permits any matrices which have been previously released to be fully and properly received in the assembling block while also it allows the slow moving, massive organs associated with the shifting apparatus enough time in which to move from one position to another. In addition, the arresting of the movement of tape I2 by the intervention of arm 54 momentarily suspends the operation of the record reader II until the shifting of carriage I25 may have had time to be fully executed.

It will be understood that numerous modifications and variations may be made without departing from the spirit and scope of the present invention. For this reason it is intended not to be limited to the specific language of the foregoing specification nor to the detailed illustrations in the accompanying drawings but to be permitted instead a latitude of interpretation as indicated by the hereunto appended claims.
