AUTOMATIC CONTROL MECHANISM FOR LINECASTING AND COMPOSING MACHINES Filed Aug. 17, 1955 4 Sheets-Sheet 4 INVENTOR EDWARD s; LARON United States Patent C AUTOMATIC CONTROL MECHANISM FOR LINE- CASTING AND 'COMPOSING MACHINES Edward Stanley Larson, Chicago, 11]., assignor, by mesne assignments, to Fairchild Camera & Instrument Corporation, a corporation of Delaware Application August 17, 1955, Serial No. 528,941

7 Claims. (Cl. 199-61) The present invention relates to improvements in linecasting and composing machines and more particularly to automatic control mechanisms therefor.

An. important object of the present invention is to provide control instrumentalities responsive to predetermined control signals for selectively operating an automatic horizontal rule inserter for want-ad or other composition.

The historical background of the art with which the present invention is concerned will first be presented. The lines of type or slugs pgoduced by line-casting and composing machines of the general class shown and described in United States Patent No. 436,532, dated September 16, 1890, are made through the instrumentality of matrices which consist of small brass units (or matrices) carrying indented characters in their edges. Thus, when these matrices are assembled into a line of predetermined length in the assembly elevator, they are delivered to a casting position whereat the slugs or lines of type are cast and ejected or delivered from the casting position into the galley where they are collected.

In the class of composition exemplified by want-ad composition, each want-ad is set off from the adjacent one by a horizontal line extending almost the full column width. This line is called a horizontal rule and takes the form of a thin metal plate which is inserted between the proper slugs or lines of type. in accordance with the present invention, means is provided for inserting these plates (horizontal rules) automatically. Without this automatic means it is necessary to insert these plates manually, and this process consumes a considerable amount of time because the type must he read in order to determine where the plates should be inserted. Hence with the use of the automatic device according to the present invention, a signal or code combination representing the horizontal rule is introduced in the control form (for example, perforated tape) during the preparation thereof representing lines of composed matter for the production of these slugs or lines of type. According to the present invention it is contemplated that the horizontal rule signal will follow the elevate signal, which elevate signal normally concludes each line of composition, as is Well known in the art. Thus, when a sufficient number of matrices has been accumulated on the assembling block ofthe assembly elevator with which a complete line may be molded, an elevator operating signal is sent through the record reader mechanism, which signal initiates the operation of the elevator, and also arrests the record reader shaft, stopping the feeding of the control form while the elevator ascends to deliver the line of matrices to the delivery slide and then descends or returns to receive the next line of matrices. Accordingly, these horizontal rule codes for a predetermined line are sensed by the record reader of the operating unit after said return of the elevator, and causes a horizontal rule to be dropped automatically at the proper time. The signals are preferably effective through the 2 instrumentality of a record reader mechanism and selectable control elements as particularly disclosed and described in United States Patent No. 2,091,286, granted August 31, 1937, to H. L. Krum et al.

The present invention is particularly concerned with the production or composition of one-line Want-ads. In this operation, an appreciable delay must be introduced between the time that the horizontal rule code combination is read or sensed by the record reader and the time that the plate is dropped. With the arrangement according to the present invention, facilities are provided for etfectively timing the release of a horizontal rule for delivery to the galley between the proper lines of type.

A more complete understanding of the invention may be had from the following detailed description thereof when considered in connection with the accompanying drawings, wherein:

Fig. 1 is a perspective view of a part of a linecasting machine embodying the mechanism according to the present invention;

Figs. 2 to 5, inclusive, are electrical circuit arrangements of various control and timing systems according to the invention;

Fig. 6 is a modification adaptable to the circuit shown in Fig. 2;

Fig. 7 is a schematic diagram of a modified form of the invention utilizing electromechanical instrumentalities, and

Fig. 8 is a fragmental view of a linecasting and composing machine.

Having reference' to Fig. 1, the horizontal rule inserter 11 according to the present invention is appropriately located on the linecasting machine in such a manner that the slicing plate or guillotine 12 is adjacent to the point at which the cast slug or line of type is delivered to the galley 13 from the casting position. The horizontal rule inserter 11 comprises a tray 14 in which a plurality of horizontal rules or plates 15 are carried. Plates 15 are iuged by spring 16 toward the slicing plate 12. Suitably positioned above plates 15 is an electromagnet 17 mounted on a bracket 18 secured to the linecasting machine in any suitable manner. To the armature 19 of the magnet 1'7 is secured an operating arm 21 appropriately hinged at 22 to the bracket'18. The free extremity of the arm 21 is adapted to be articulated pivotally to the slicing plate 12 such that upon energization of magnet 17, the plate 12 will be eifective to eject a horizontal rule 15, said plate 12 being returned by the spring 23 acting upon arm 21.

Referring to the electrical circuit diagram shown in Fig. 2, the contact 31 is provided on the operating unit disclosed in United States Patent No. 2,091,286 and is analogous to the contact 12 shown in Fig. 4 of United tates Patent No. 2,148,549. However, according to the present invention, contact 31 closes in response to the sensing of the horizontal rule code signal combination in the tape, which sensing occurs following the sensing of the elevator code signal, and after the assembly elevator has ascended to deliver the line of matrices (corresponding to the type line slug which the horizontal rule is to follow in the galley) to the delivery slide and then returned to its matrix receiving position. Thus, the linecasting machine has been put in motion to cause its cam shaft to start rotating. 5

Contact 31, upon closing, causes relay 32 to become energized over an obvious circuit. Relay 32 closes its

contacts

33 and 34, and a locking circuit is completed for relay 32 which extends from positive battery, through the winding of relay 32, through contact 33 (now closed), and through closed contact 35 of unoperated relay 36 to negative battery. On the linecasting machine are con? tacts 37 and 38 which are operated in proper timed relation by cams .carried on the cam shaft of said machine. Contact 37 closes momentarily during the first cycle of the linecasting machine camshaft, soon after the closing of contact 31 and consquent energization of relay 32, and completes an energizing :circuit for relay 36 extending from positive battery, through the winding of relay 36, to junction 39, then through contact 34 (now closed) to junction 41 and through contact 37 to negative battery. Relay 36 upon operating, opens its contact 35 and closes its contacts 42 and 43. Contact 35, upon opening, breaks the locking circuit for relay 32 causing said relay 32 to release. Relay 36 becomes locked up over a circuit extending from positive battery, through the winding of relay 36 to junction 39, thence through contact 42 (now closed) of relay 36, and through closed contact 45 of relay 44 to negative battery.

Contact 38 now closes momentarily at approximately .50 rotation of the linecasting machine cam shaft, which in turn causes relay 44 to be energized over a circuit extending from positive battery, through the winding of relay 44, through contact 43 (now closed) to junction 48 and then through contact 33 (while closed) to negative battery. Other circuits controlled by contact 38 are open at this time. Relay 44, upon energizing, opens its contact 45 to break the locking circuit for relay 36, and closes its

contacts

46 and 47. Relay 44 becomes locked up over a circuit extending from positive battery, through the winding of relay 44 to junction 48, then through contact 46 (now closed) of relay 44, and through closed contact 49 of relay 51 to negative battery.

It should be pointed out here that the next horizontal rule signal may be introduced immediately, because rclays 36 and 32 have been restored to their deenergized condition. If relay 32 is again operated upon the reclosure of contact 31 (in response to the next horizontal rule signal), said relay 32 will be locked up, as previously described, and the horizontal rule selection will not be lost. With this arrangement lines containing only the horizontal rule signal in addition to the elevator signal may be composed; that is, successive horizontal rules may be dropped or delivered to the galley without the introduction of intervening characters. This means that the next series of signals in the tape need contain only the horizontal rule and the elevate signals, and need contain no other characters for proper functioning. Such operation may find many advantageous applications.

Continuing the present description, the second closure of contact 31 resulting from the horizontal rule selection, again operates relay 32 which is locked up through relay 36, as previously described. Then, in the second cycle of the linecasting machine cam shaft, contact 37 again closes momentarily which again operates relay 36 through contact 34 of relay 32 thus releasing relay 32. jIti's noted that relay 36 does not lock up at this time because its locking circuit is open at contact 45 of relay 44 which is still energized. However, because of the condenser 55 inserted across relay 36, the release of relay 36 is delayed for a purpose which will presently appear.

In addition, contact 37, upon closing this time, also causes the energization of relay 51 over a circuit extending from positive battery, through the winding of relay 51, through contact 47 (still closed) to junction 52, then through contact 37 to negative battery. Relay 51, upon energizing, opens its contact 49 to break the locking circuit for relay 44, and closes its contacts 53 and 54. Because of the closure of contact 45 at this time, the locking circuit for relay 36 is established before the condenser 55 is discharged, thus holding contacts 42 and 43 of relay 36 closed. A locking circuit for relay 51 is established from positive battery, through the winding of relay 51 to junction 56, through contact 53 (now closed) of relay 51 and through closed contact 57 of relay 58 to negative battery.

A similar situation exists when contact 37 operates relay 44 through contact .43 of relay .36 and inasmuch as condenser 60 introduces a delay in the release of relay 44 it is necessary that condenser introduce a greater delay in the release of relay 36 so that relay 36 will remain operated long enough to establish its locking circuit through contact 45 on relay 44. Values of condensers 55 and must be chosen accordingly.

As the cam shaft of the linecasting machine rotates substantially 50 further, the contact 38 again closes momentarily which causes relay 44 to re-energize through contact 43 of relay 36. Relay 36 thus de-energizes because contact 45 of relay 44 is now opened, breaking the locking circuit for said relay 36. Also pursuant to the closure of contact 38 at this time, the relay 58 is caused to become energized over a circuit extending from positive battery, through the winding of relay 58, through contact 54 (now closed), over conductor 5) and through contact 38 to negative battery. Relay 58, upon energizing, opens its contact 57 to break the locking circuit for relay 51, and closes its contacts 61 and 62. A locking circuit for relay 58 is established from positive battery, through the winding of relay 58 to junction 63, then through contact 61 (now closed) of relay 58, and through closed contact 64 of relay 65 to negative battery. Condenser 60, as previously mentioned, is placed across energizing coil of relay 44 in order to delay the opening of contact 47 and thus insure that relay 51 has sufficient time to operate and lock up. Condenser 55, however, should be of a value to in troduce a greater delay than condenser 60 to insure correct operation, as previously described.

Now that relay 36 is released, it is possible to receive and store another horizontal rule signal in relay 32 although it is impossible for it to come in this early because of the fact that the linecasting machine is full andthe operating unit must wait until it can accommodate additional lines. To understand the utility of this transfer, it should be borne in mind that coincident with the transmission of a horizontal rule signal there is set up in accordance with the composing mechanism control, an assembled line of matrices in the assembly elevator with which the particular horizontal rule signal is to apply, and the dropping of the horizontal rule immediately after the ejection of this line (slug) must await the transfer of this line of matrices to the casting position or station on the linecasting machine. In other words, the most recently assembled line of matrices does not at once proceed to the casting position, but instead awaits its sequence. This delay is caused by a characteristic operation of commercial types of linecasting machines whereby the composing mehanism is adapted to entertain a particular line of composition at the composing level, exemplified by assembly elevator 25, Fig. 8, during the same instant in which a preceding line is suspended in the line delivery slide level 26 awaiting transfer to the casting chamber 27, and in which a third line is being entertained in the casting chamber proper and is actively performing the slug casting operation. Since three lines of composition may at the same instant be in various stages of progress, it is necessary that means he provided for storing their three associated horizontal rule control signals.

Accordingly, with the control circuit shown in Fig. 2, the most recently composed line finds its associated horizontal rule signal stored in the relay 32, the intermediate waiting line of composition in the relay 44, while the active line finds its horizontal rule signal stored in the relay 58.

On the third cycle of the linecasting machine, contact 37 again momentarily closes, and performs or controls the same stepping features as previously described plus one additional function. This time the closure of contact 37 completes an energizing circuit for relay 65 ex tending from positive battery, through the winding of relay 65, through contact 62 (now closed) of relay 58, over conductor 66 and through contact 37 to negative battery. Relay 65, upon energizing, opens its contact 64 to break the locking circuit for relay 58, and closes its contact 67. Power is now applied to the operating magnet 17 of the guillotine over an obvious circuit in response to which the blade 12 descends and slices oif or ejects one horizontal rule 15 which thereupon drops into the galley, in juxtaposition to the proper slug or line of type. A condenser 68 is inserted across relay 65 to delay the release of relay 65 so that the operating magnet 17 of the guillotine is given sufiicient time for its complete operation.

As previously mentioned, the third closure of contact 37 not only causes the operation of the guillotine but also initiates the stepping sequence of relays 32, 36, 44, etc., in the manner previously described. Now, upon each successive closure of contact 37 these two functions; namely, operation of the guillotine magnet 17 and stepping of the sequence relays will occur concurrently. Of course, contact 37 will close during every cycle of the linecasting machine regardless of whether a horizontal rule occurs or not, because said closure of contact 37 occurs in response to the elevator signal which concludes every composed line and initiates a cycle of operation of the linecasting machine. However, the dual control by contact 37 (before mentioned) occurs only when a horizontal rule signal follows an elevator signal. Thus, if a cast line or slug is not to be followed by a horizontal rule, then the linecasting machine operation will proceed normally. Therefore, with the circuit arrangement described herein the linecasting machine may be conditioned for the production of one-line want-ads, or two-or-more-line want-ads.

In Fig. 3 is shown a modification of the circuit illustrated in Fig. 2. The control circuit arrangement shown in Fig. 3 is readily adaptable to either alternate mold or single mold operation. The average linecasting machine contains four molds, each of which is adjusted to a certain height and width of slug. In slow speed operation, single mold operation is usually utilized. In this mode of operation, only one of the four molds is used in any particular composition, which means that four different kinds of composition can be handled with very little change on the machine. In this type of operation, too, the cast slug is ejected in the first cycle of the cam shaft. This is not so with alternate mold operation. Alternate mold operation is used mostly in high speed operation because it allows more time for cooling of the mold. In this type of operation, two of the four molds are used in the same composition. In any given cycle of the cam shaft the line which is cast is not the same line which is ejected and therefore it requires one additional cycle to eject.

The circuit illustrated in Fig. 3 is substantially identical to that shown in Fig. 2 except that with the circuit shown in Fig. 3 provision is made for control of linecasting machines utilizing either single mold or alternate mold operation.

To avoid repetition, the reference numerals in Fig. 3 are the same as in Fig. 2 except that where they appear they are advanced or increased by 100. Otherwise the same description applies to Fig. 3 as in Fig. 2. Moreover, the circuits in Figs. 2 and 3 are substantially identical except that a double-pole double-throw switch 171 has been added to the circuit shown in Fig. 3 to make it more versatile. As shown in Fig. 3, the switch 171 cmbraces the contact terminals of

contacts

143 and 142 of relay 136, so that when the switch 171 is thrown to the upper position shown in Fig. 3, the relays 144 and 151 are by-passed by the conductors 172 and 173 which extend to the terminals 174 and 175 of contacts 154 and 153 respectively of relay 151. When the switch 171 is thrown to the upper position, the circuit may be used for single mold operation, and when the switch 171 is thrown to the lower position, it is adaptableto alternate mold operation.

In Fig. 4 is illustrated a further modification of the 6 circuit shown in Fig. 2. Thecircuit illustrated in Fig. 4 is substantially identical to that shown in Fig. 2 except that the switches 37 and 38 of Fig. 2 (numbered 237 and 238 in Fig. 4) associated with the cam shaft of the linecasting machine have been combined into one switch of the transfer or break-make type. Thus, contact 238 is normally closed, except for the time or interval that contact 237 is open. The double-pole double throw switch 171 shown in Fig. 3 is also applicable to the circuit shown in Fig. 4, thus adapting the circuit shown in Fig. 4 for either single mold or alternate mold operation. To avoid repetition, the reference numerals in Fig. 4 are the same as in Fig. 2 except that they, where shown, are advanced or increased by 200. Otherwise the same description applies to Fig. 4 as in Fig. 2.

In Fig 5 is shown a still further modification of the circuits shown in Figs. 2 and 4. The reference numerals in Fig. 5 are the same in Fig. 2 except that they are advanced or increased by 300. Contact 341 upon closing, causes relay 332 to become energized over an obvious circuit, closing its

contacts

333 and 334. A locking circuit for relay 332 is completed through contact 335 of relay 336. Contact 337, upon closing, completes an energizing circuit for relay 336 through contact 334 (now closed). Relay 336 upon energizing closes its

contacts

342 and 343, and opens its contact 335 to release relay 332. Relay 336 becomes locked up through contact 345 of relay 344.

When contact 337 opens, contact 338 closes which causes relay 344 to become energized through contact 343 (now closed). Analogous to the circuit shown in Fig. 2, other circuits controlled by contact 338 are open at this time. Relay 344 upon operating, opens its con tact 345 to break the locking circuit for relay 336, and closes its contacts 346 and 347. Relay 344 becomes locked up through contact 349 of relay 351.

Similar to the operation of the circuit in Fig. 2, the second closure of contact 331 again operates relay 332, which looks up through contact 335 (now closed). Then, when contact 337 again closes, relay 336 again operates through contact 334 thereby releasing relay 332. Contact 337 upon closing this time also causes the energization of relay 351 through contact 347 (now closed), thus opening its contact 349 to release relay 344, and closing its contacts 353 and 354. Relay 351 locks up through contact 357 of relay 358. Upon the closure of contact 338, relay 344 is re-energized through contact 343 of relay 336. Relay 336 then de-energizes because contact 345 of relay 344 is opened. Also pursuant to the closure of contact 338, the relay 358 is energized, thereby opening its contact 357 to break the locking circuit for relay 351, and closing its contacts 361 and 362. Relay 358 is locked up over a circuit extending from positive battery, through the winding of relay 358 to junction 376, then through contact 361 (now closed), over conductor 377, through normally closed contact 378 of make-before-break switch 379 to negative battery.

Thus, operation of the circuit (shown in Fig. 5) to the point where relay 358 is operated through contact 354 of relay 351 upon the closure of contact 338 is identical to that disclosed in Fig. 2 (modified by

contacts

237 and 238, Fig. 4). However, in the circuit arrangement shown in Fig. 5 the closing of contact 337 produces through contact 362 of relay 353 an energizing circuit directly for magnet 17 of the horizontal rule inserter 11, extending from negative battery, through contact 337 (when closed), over conductor 366, through contact 362 (now closed), over conductor 381 to junction 382', then over conductor 383, through the winding of magnet 17, over conductor 384 and through contact 385 to positive bottery. As soon as armature 19 is attracted to cause operating lever 321 to rotate clockwise (as viewed in Fig. 5), arm 386 thereof permits contact 387 of make-before-break switch 379 to close, which now establishes an energizing circuit for magnet 17 extending from negative battery, through contact 387 (now closed), to junction 382, over conductor 383, through winding of magnet 17, over conductor 384, and through contact 385 (still closed) to positive battery, so that the continuing operation of the horizontal rule inserter 11 is now entirely independent of relay 358. Next, upon further clockwise rotation of lever 321 contact 378 is permitted to open to break the locking circuit for relay 358 causing relay 358 to release. As the operating lever 321 continues to rotate clockwise, its arm 388 strikes the shoulder 339 of component 391 and causes component 391 to slide in an upward direction, which finally causes contact 385 to open. The opening of contact 385, or course, opens the circuit to the operating magnet 17 of the horizontal rule inserter 11, and thus causes it to release. Component 331 is clamped down friction tight so as to retain .frictionally any operated position. Thus, arm 383 may now leave shoulder 389 without closure of contact 385 until arm 388 strikes the shoulder 392 of component 391 in response to the subsequent counterclockwise rotation of operating lever 321. At the time that arm 388 strikes shoulder .392 to cause component 391 to move downwardly to thereby permit contact 385 to again close, it substantially simultaneously operates the contact pile 379 to cause contact 378 to close and contact 387 to open in make-before-break fashion. The opening of contact 337 breaks the energizing circuit for magnet 17. Since relay 358 is also released, there is I no operating circuit for the magnet 17. However, the next time relay 358 is operated from contact 338, and then contact 337 is subsequently closed, a repetition of the operating cycle just described of the horizontal rule inserter 11 will occur.

In Fig. 6 is shown a modification of Fig. 2 to improve the timing thereof. When the operating unit contact 431 closes in response to the horizontal rule signal, the relay 432 is operated, and locks up through contact 433 to positive battery 439. When the linecasting machine cam shaft starts rotating, contact 437 closes, which operates relay 436 through contact 434 (now closed). At this time, the closing of contact 435 (due to the energization of relay 436) applies negative battery on the right side of condenser 471. It is well known that a large condenser will momentarily act as a short circuit when a charging circuit is closed. Therefore, effectively, the operating winding of relay 432 is short circuited, and is caused to release. A short time later, condenser 471 charges completely which indicates that full voltage plus potential exists on the left side of the plate. Thus. relay 432 can again be operated and locked up without having to wait for the release of relay 436. Resistance 472 of high value is placed across condenser 471 to allow condenser 471 to be fully discharged, and thus permit the repetition of the operation just described.

in Fig. 7 is illustrated an embodiment of the present invention wherein

electromechanical devices

511, 512, and 513 are employed to store the horizontal rule signal condition during the transfer of its associated line ot matrices from the matrix assembly position (assembly elevator), through the line delivery position, to the casting position (where the type line slug is cast and ejected into the galley following which the horizontal rule inserter is operated if called upon by a horizontal rule signal to drop a horizontal rule in juxtaposition with said type slug). Since in continuous one-line want-ad operation, wherein a horizontal rule is inserted between every line. and since it is possible to entertain simultaneously a line of matrices in each of the three aforementioned positions or stations in the linecasting machine. there are shown three

electromechanical devices

511, 512, and 513.

Each

electromechanical device

511, 512 and 513 comprises a stepping magnet 514, and a restoring magnet 515. The armature 516 ofeach magnet 514 carries at it .free end a drive pawl .517 adapted to cooperate with a spring biased ratchet member 518 rotatably mounted on a shaft 519. The driving of the ratchet member 518 rotatably against the pull of its spring 520 is done by the armature return spring 521 following each release or deenergization of the magnet 514, as will presently appear.

The ratchet member 518 is retained in each stepped position by a detent pawl 522 controlled by the restoring magnet 515. During the restoring operation, the magnet 515, is operated, as will presently appear, and the pawl 522 is held away from the ratch teeth and also cooperates with an arm 523 of drive pawl 517 to also hold the pawl 517 away from the ratchet 518 to permit the spring 520 to rotate the ratchet member 518 counterclockwise against the stop 524. Ratchet member 518 is provided with an indicating arm 525 which cooperates in its home position with a contact pile-up or bank 526, and in its fully operated position with a contact operating member 527. Connected in series with the restoring magnets 515 of each of the electromechanical devices 511 512, and 513 is the operating magnet 528 (analogous to magnet 17, Fig. 'l of the horizontal rule inserter 592 (analogous to the horizontal rule insertcr 11).

Referring further to Fig. 7, the contact 531 (analogous to contact 31, Fig. 2) is located in the record reader and is closed in response to the sensing of the l1orizontal rule code signal in the tape. When contact 531 is thus closed a circuit is completed for the energization of the stepping magnet 514 of the electromechanical device 511, extending from positive battery, through contact 531 (when closed), over conductor 532, through contact 533 (now closed) of contact bank 526, over conductor 534 and through the winding 514 (of device 511), tonegative battery.

Pursuant to the closure of contact 531 and energization of magnet 514 of device 511, armature 516 is attracted to cause pawl 517 to engage the next tooth on ratchet 518,, so that when contact 531 is opened and magnet 514 is released, the spring 521 will return the armature 516 against the stop 535 and cause pawl 517 to rotate ratchet member 518 one step to bring pointer 525 into register with position l." In this condition of operation of device 511, the contact 533 will be opened, and the

contacts

536 and 537 will be closed. On the linecasting machine is a contact 538 which is operated in proper timed relation by a cam 53? carried on the cam shaft of :said machine. In the present embodiment of the invention only a single contact operated by the linecasting machine is required.

When contact 538 closes momentarily soon after the closing and opening of contact 531, the stepping magnet 514 of device .511 is energized a second time o er a circuit extending from positive battery, through contact 538 (when closed) over conductor 540 to junction 541, then over conductor 542, through contact 537 (now closed) of contact bank 526 of device 511, over conductor 534 and through the winding of magnet 514 to negative battery. Magnet 514 (of device 511) upon operating and releasing causes pawl 517 thereof to rotate ratchet member 518 one more step to position "2.

Pursuant to the next closure of contact 531 in response to a horizontal rule signal, an energizing circuit is established for operating magnet 514 of device 512 extending from positive battery, through contact 531 (when closed), over conductor 532, through contact 536 (now closed), over conductor 543, through contact 544, over conductor 545 and through the winding of magnet 514 of device 512 to negative battery. Thus, in a manner similar to that previously described in connection with device 511, the ratchet member 518 of device 512 will be operated to position "1, thereby permitting contact 544 to open, and

contacts

550 and 546 to close. Then when contact 538 again closes momentarily after the closing and opening of contact 531, the magnet 514 of device 9 511 will again be operated over the previously described circuit from contact 538 to rotate ratchet member 518 to position 3, and also an energizing circuit for magnet 514 of device 512 will simultaneously be established from positive battery, through contact 538 (when closed), over conductors 540 and 547, through contact 536 (now closed), over conductor 545 and through the winding of magnet 514 of device 512 to negative battery, whereupon ratchet member 518 of device 512 will be rotated to position 2.

Now, upon the next closure of contact 531 in response to another horizontal rule signal, an energizing circuit is established for operating the magnet 514 of device 513 extending from positive battery, through contact 531 (when closed), over conductor 532, through contact 536 (still closed), over conductor 543, through contact 550 (now closed), over conductor 548, through contact 549, over conductor 551 and through the winding of magnet 514 of device 513 to negative battery. Thus, in a manner similar to that previously described in connection with

devices

511 and 512, the ratchet member 518 of device 513 will be operated to position 1, thereby permitting contact 459 to open, and contact 552 to close. Then when contact 538 again closes momentarily after the closing and opening of contact 531, the magnet 514 of device 511 will be operated again over the previously described circuit from contact 538 and upon release will rotate ratchet member 518 thereof to position 4 to effect the closure of contact 553. Simultaneously, magnet 514 of device 512 will again be energized over the previously described circuit from contact 538 to effect the rotation of ratchet member 518 of device 512 to position 3, and a circuit will be comgarages the winding of magnet 528 to negative battery, whereupon a horizontal rule will be' dropped into the galley. Device 512 is now restored to its zero or home position.

Now, when contact 531 again closes device 512 will be again stepped to position 1, and when contact 538 closes momentarily, device 511 will be stepped to position 3, device 512 will he stepped to position 2, and device 513 will he stepped to position 4. Device 513, by stepping to position 4 will close its contact 563 to establish an energizing circuit for restoring-magnet 515 of device 513 in series with magnet 528 over a circuit extending from positive battery, through contact 563 (now closed), over conductor 564, through winding of magnet 515 of device 513, over

conductors

565, 566 and conductor 557, and through the winding of magnet 528 to negative battery, whereupon a horizontal rule will be dropped into the galley. Device 513 is now restored to its zero or home position in the same manner as described in connection with device 511.

It is noted that once a

device

511, 512 or 513 is initiated. by the closure of contact 531, the stepping of the initiated device continues stepwise upon each closure of contact 538 until the

respective contact

553, 561, or 563 is closed, whereupon restoration of the

respective device

511, 512 or 513 occurs. It will also be noted that the timing is such as to allow a line of matrices,

pleted for the energization of magnet 514 of device magnet 514 of device 513 to negative battery, whereupon ratchet member 518 of device 513 will be rotated to position 2 after release of armature 516.

However, when contact 553 was closed, as just described, an energizing circuit for the operating magnet 528 of the horizontal rule inserter 529 was established from positive battery, through contact 553 (now closed), over conductor 555, through the winding of restoring magnet 515 of device-511, over

conductors

556 and 557 and through the winding of magnet 528 to negative battery. A condenser 558 is placed across the energizing coil of restoring magnet 515 of device 511 in order to delay the discharge or release of magnet 515 and thus insure the return of ratchet member 518 against stop 524. For the same reason, similar condensers are placed across the magnets 515 of

devices

512 and 513. Similarly, a condenser 559 is inserted across the operating magnet 528 so that the guillotine of horizontal rule inserter 525 is given sufficient time to complete the operation of dropping a horizontal rule.

Accordingly, at the instant just described, the device 511 has been restored to its normal 0 or home position (shown in Fig. 7), device 512 is in position 3, and device 513 is in position 2. Now, if contact 531 is again closed in response to a horizontal rule signal, device 511 will be stepped to position 1 as previously described, and when contact 538 closes momentarily, device 511 will he stepped to position 2, device 512 will he stepped to position 4, and device 513 will he stepped to position 3 over previously described circuits. However, device 512 by stepping to position 4 will close its contact 561 to establish an energizing circuit for restoring magnet 515 of device 512 in series with magnet 528 over a circuit extending from positive battery, through contact 561 (now closed), over conductor 562, through the winding of magnet 515 or device 512, over

conductors

563, 564, and 557, and through which is to be followed by a horizontal rule, to progress through the various stages or positions in the linecasting machine before the horizontal rule is dropped or inserted.
