, Renewed January 2, 1934 80 Claims.

The invention relates to composing machines and more particularly to automatically controlled line casting machines. The objects of the invention are to provide an improved compact selector or control mechanism adapted to be embodied as a unit in a standard line casting machine, and cooperate directly with the. key-controlled mechanisms thereof to effect the automatic assembling of the matrices; to provide imlO proved means for effecting the operation of the selector mechanism and which is preferably in the form of a tape-controlled, electrical transmitter that may be located adjacent or at a distance from the composing machine; to provide improved means for measuring the line of assembled matrices and which is variably operated in accordance with the number of wedge-shaped space bands in the assembled lines, and to provide means governed by the line measuring device for controlling or safe-guarding the automatic operation of the composing machine; to provide la shift mechanism adapted to be applied to a composing machine.

With these and other objects in view, the invention consists in the features of improvement hereafter set forth, illustrated in the preferred form inthe accompanying drawings, and more particularly pointed out in the appended claims.

Figs. 22 and 23 show a bold vand'roman face attachment.

The selector or control unit A (see Figs. 4 and 7) is of compact construction, and such that it can be mounted in a standard line casting machine, for example, the linotype, directly behind the keyboard, and when so mounted `it will cooperate with the key-restoring weights of the machine to release the matrix operating cams.

The frame of the selector unit comprises a lower horizontal supporting base or bar 1, an upper horizontal bar 2 spaced from the lower bar, end brackets 3, front and rear fixed bars 4 and 5 and a magnet supporting plate 6 at one end. A set of six code or permutation bars 7 are horizontally disposed between the lower and upper bars 1 and 2, and slide longitudinally through guide openings formed in the end brackets 3 so that each code bar is shiftable to either one of two positions, the movement being limited by guide pins 8 fixed to the bars 1 and 2 and extending through slots in the code bars.

The code or permutation bars '7 are provided on both their front and rear edges with V-shaped notches 9, and the bars cooperate with two series of vertically disposed selector rods 10 arranged on opposite sides of the bars and provided with anti-friction rollers 11 which are pressed into engagement with the notched edges of the bars by spring iingers 12. The rods 10 are provided with notches near their upper ends and the projecting edges of a thin plate 13 on the upper face of the bar 2 extends within the notches and clamp bars 14 engage the upper end portions of the rods and hold them in engagement with the plate 13. The spring fingers are preferably in the form of depending extensions on thin strips l5, andthese strips and the clamp bars `14 are secured to cross pieces 16 which are secured to the upper frame bar 2 by screws extending therethrough and through a strip 1'7 which holds the plate 13 in position.

The `base 1 of the selector unit is in the form of a comb-bar and is provided with a series of integral, upwardly and forwardly projecting guide fins or plates 18. The front and rear series of rods 10 extend within the spaces between the guides 18 and are provided with rearwardly and forwardly offset portions respectively, and terminate in depending ends 19 which extend within V-shaped notches in the upper edges of a series of selectable controlling levers 20. The latter are disposed between the guide iins or plates 18 and are free to move longitudinally and also oscillate. As shown, each lever has two'lugs 21 and 22 on its lower edge which normally engage a horizontal seat 23 on the bar 1 and maintain engagement with such seat during the longitudinal movement of the lever. The lug 22 of each lever is disposed below the extension 19 of the corresponding rod 10 and forms a fulcrum upon which the lever can oscillate, as shown in Fig. 6.

The levers 20|are provided with upturned forward end portions 24 and the forward ends of the levers connected. to the front and rearseries of rods 10 are correspondinglydisposed, when in normal position, in front and rear of the path of vertical .movement of a universal bar 25. The latter is carried upon a pair of bell-cranks 26 (only one of which is shown) pivotally mounted on the fixed bar 4 and connected to a longitudinally movable actuating bar 27. The bars 25 and 27 engage guide slots` inplates 28 on the frame bar 4 and are held in normal position by a spring 29. The universal bar 25 is provided with a beveled edge which is arranged to cooperate with V-shaped notches in the upturned forward ends of the levers 2l), and the rear ends of the levers are disposed between shoulders 30 on the key-restoring weights 31 of the line casting machine.

'Ihe permutation bars 7 are each normally held Iin their left-hand positions by a series of springs 32 and these bars and the bar 27 are shifted to the rightby a series of pins 33 slidably mounted in the plate 6, and engaged by adjusting screws 34 on the ends of a series of armature levers 35. These armature levers are pivoted in magnet frames 36 which are secured to the plate 6. The armature levers for shifting the permutation or code bars '7 are controlled by a set of six selector magnets 37. The armature for shifting the operating bar 27 is operated .by a magnet 3,8.

By means of the magnets 37, the permutation or code bars 7 are positioned in different combinations and these bars are so notched that, in any setting, one of the rods 10 will be selected and shifted by its spring into a series of aligned notches of the bars and thereby moves thecorresponding lever 20 longitudinally. If the selected rod is one of the series in front of the permutation bars, the corresponding lever is shifted rearwardly; whereas the selection of one of the rods in rear of the bars will move the corresponding lever forwardly. In either event, the forward end 24 of the selected lever is brought into the path of movementv of the `universal bar 25 and, when the bar 27 is shifted longitudinally by the operating magnet 38, bar 25 is depressed andthe selected lever is oscillated, as shown in Fig. 6, to

' operate the corresponding matrix escapement escapement 44. If desired, as shown in Fig.'2,

the controlling levers 20 of the selector unit could, through the medium of interposed parts 45, directly operate the reeds 43.

The selecting and operating

magnets

37 and 38 could be controlled and timed in operation in response to telegraph signals having six selecting units and transmitted over a single line wire from a distant station. But since the operation of the selector which controls the matrix assembling mechanism of the composing machine must be arrested during the transfer of the assembled line of matrices to the casting mechanism, the operation and timing of the magnets is preferably effected by a local, motor-driven transmitter under control of a perforated tape. As shown in Fig. 3, the tape 46 has transverse rows of holes, each row having six code hole positions and representing a character or signal. The tape is also provided, asA usual, with feed holes and, like telegraph tape now in use, can be prepared by a keyboard perforator or by a receiving reperforator which is responsive to selecting code signals transmitted from a distant station.

The tape selectively controls a series of six bellcrank levers 47 mounted on a pivot rod 48. The depending arms of these levers are spring-held in contact with a pivoted spring-held universal bar 49, and the horizontal arms of the levers are provided with a series of contacts 50, one for the circuits of each of the selecting magnets 37. The levers 47 are also provided with forwardly extending arms 51 having upturned ends provided with pins 52 in line with the code hole positions of the tape. The universal bar is oscillated to move the feeler pins 52 into and out of engagement with the tape by a cam 53 on a motor-driven shaft 54 and through the medium of a springheld lever 55 having a follower or roller engaged by the cam and an arm engaging a. lug 56 on the universal bar.

An additional spring-held lever 57 on the pivot 48 is also shifted by the universal bar 49 and carries a feed pawl 58 which operates a ratchet 59 and a pin toothed tape feed wheel 60. The circuit of the operating magnet 38 is controlled by a commutator disk 61 and brush 62, the latter being mounted on the upper end of the shaft 54. A gear 63 loose on the shaft is continuously driven by a motor 64 and is connected thereto by a, shiftable clutch member 65. A spring 66 tends to hold the' clutch closed and a pivoted spring-held arm 67 is arranged to cooperate with a cam 68 on the movable clutch member 65 to open the clutch and hold it open. The armature of a magnet 69 1s fixed to the start-stop lever 67 and when energized holds the arm or lever in inoperative position, and, since the magnet is normally energized, the clutch is engaged to effect the rotation of the cam 53 and brush 62. As the cam 53 rotates, the levers 47 and 57 are relieved of the pressure of the universal bar 49, and the springs of the levers tend to lift the feeler arms 51 and feed pawl 58. The pins registering with the holes in a row of perforations on the tape will permit the feeler arms to rise high enough to close the circuits of 1,40 the corresponding selector magnets 37 and thereby effect the movement of the corresponding permutation bars of the selecting or control unit. But the blank portions of the tape will prevent the energization of the other selecting magnets. Shortly after the selector magnets are thus energized, the brush 62 'closes the circuit ofthe operating magnet 38 and the selected lever of the control unit is operated as described, bythe universal bar 25. The reverse movement of the levers 47 and 57, effected by the universal bar 49, opens the circuits of the magnets 38, withdraws the feeler pins from the tape and advances the tape one step to bring the next row of perforations into operative position.

The cam 53 and the commutator 61 and its brush 62 are so related that the selector magnets 37 are energized before the operating magnet 38, and the latter is de-energized before the circuits of the selector magnets are opened. Thus, in Fig. 18, in which the horizontal dimensions of the lines a and b represent the time of one revolution of shaft 54, the high part of line a represents the period during which the selector magnets are energized and the high part of line b represents the period during which the circuit of the operate ing magnet is closed.

Figs. 16 and 17 show a modification of the controlling and timing means for the magnets, in which the motor-driven shaft 54 is provided with a cam 53 for operating the feeler pin levers and also with a cam 70 for opening and closing contacts 71 interposed in the circuit of the operating magnet 38. With this arrangement, while the circuits of the selector magnets 37 are closed rst, these magnets are de-energized before the circuit of magnet 38 is open. Thus, in Fig. 19, the line a' represents the movement of the feeler pins as effected by the cam 53', and the high portions of the lines a2 and b' represent the times of closed circuit of the selecting and operating magnets respectively:

During each cycle of operation, with the arrangement shown in Fig. 3, the operating magnets 37 hold the corresponding permutation bars 7 in their shifted positions during the operation of the universal bar 25 which is effected by the magnet 38. With the controlling and timing means shown in Figs. 16 and 17, additional means is required for holding the selected permutation bars in shifted position. Forthis purpose, springheld latches 72 (Figs. 4 and 5) are`arranged to engage notches in the selected permutation bars to retain them in shifted position. A corresponding series of spring-held releasing pawls 73 are mounted on a bracket 74 that is fixed to the righthand end of the bar 27. The longitudinal movement of this bar to the right, effected by the magnet 38, permits the engagement of the pawls 73 with forwardly projecting arms 75 on the latches 72, so that, when magnet 38 is de-energized and bar 27 moved to the left by its spring, the latches 72 are released and the shifted permutation bars restored by their springs 32. At the end of the return movement of bar 27, the pawls engage a fixed abutment 76 on the frame of the selector unit and are thus disengaged from the latches.

Normally, during the assembling of a line of matrices, the circuit of the magnet 69 (see Fig. 3) is closed, clutch 65 is engaged and shaft 54 rotates continuously. At each revolution, the- When the tape is fed directly from a perforator,

it is passed beneath an arm 79 (see Fig. 3) on a rock shaft 80. -The latter is provided with an arm 81 which normally holds a pair of contacts 82 in engagement. These contacts are 'interposed in the circuit of the stop-start magnet 69 and, if the operation of the perforator fails to keep pace with thatV of the transmitter, the tension of the tape shifts the rock shaft and opens this circuit. Arm 67 then disengages clutch member 65 and arrests the transmitter and the composing machine controlled thereby.

To permit the operation of the composing machine in accordance with a six-unit telegraph code, and also provide for both upper and lower case characters, the selector unit is provided with an additional permutation ybar 83 (see Figs. 4, 5, and 7) which is operated, not by a selector magnet, but under control of the other bars. Thus, upon receipt of a special upper case shift signal, the magnet-operated permutation bars 7 are positioned to effect the selection and operation of a lever 20a, this lever, when oscillated by the universal bar 25, instead of operating a matrix escapement, shifts a bell-crank lever 85 (see Figs. 4 and 7), and the latter cooperates with the inclined cam edge of a notch 86 in the bar 83 to move it to its right-hand position. Then the continued operation of the controlling mechanism will effect the selection of upper case matrices. A similar lever 20b effects the operation of a bellcrank 85 in response to a lower case signal andthe latter co-operates with a cam notch 86' to restore the shift permutation bar. Preferably, as

shown, the bell-crank levers 85 and 85' operate in'guide slots in the fixed bar 5. The shift permutation bar 83, like the others, is provided with cam notches on both sides. With this arrangement, it is possible to employ a six-unit code to select over one hundred and twenty characters.

A special lever controlled by the selecting unit and the operation of which is effected by the universal bar in response to a line or elevato-r signal, instead of operating a matrix escapement, closes a switch contact 87 (see Fig. 3). When this contact is thus closed on the completion of the assembling of a line of matrices, a circuit is completed from battery 88 by

conductors

89 and 90, through the coil of a relay 91. The operation of this relay closes a holding circuit from a battery 92 through the front contact of a switch 93, conductor 94, normally engaged contacts of switch 95, conductor 96, normally engaged contacts 97, and

conductors

98 and 90, through the coil of relay 91. Thus, when this relay is energized by the operation of the switch 87, its circuit remains closed independently of this switch. The shift of relay contact 93 also opens a normally closed circuit from battery 92, through conductor 98 and the circuit of a slow-release relay 99.l The release of the armature of this relay closes a circuit from a. battery 100 through a relay 101 and the latter closes a circuit from a battery 102 through a solenoid magnet103. The core of this magnet (see Fig. 1) is connected to an arm 104 on the elevator rock shaft 105 of the standard line casting machine and which, as usual, is provided with an arm 106 connected by a link 107 to the elevator 78. It is noted that a time interval intervenes after the receipt of a line o r elevator signal before the elevator magnet 103 is energized, to permit the positioning of the last few matrices making up the line on the elevator.

The operation of the relay 91 also shifts" a switch 108 which is interposed in the normally closed circuits of the transmitter stop-start magnet 69. This circuit may be traced as followsz From battery 109 through the coils of magnet 69, conductor 110, contacts 82, conductor 111, normally closed

contacts

112 and 113, conductor 114, the normally closed contact of a switch 115, conductor 116 and the normally engaged contact of relay switch 108 to ground. The receipt of aline or elevator signal thus arrests the shaft 54 of the controlling transmitter after a single revolution. To avoid the operation of the selector unit during this revolution, the row of perforations of the tape following the perforations representing a line or elevator signal, is of such a nature that it will not effect any complete operation of the selector mechanism.

In addition to opening the circuit of thetransmitter stop-start magnet 69, the switch 108 closes a circuit from a battery 117 through a signal lamp 118 and a conductor 119 through relay switch 108 to ground.

The initial movement of the core of the solenoid magnet 103 and the elevator 78 operated thereby, opens the normally closed contacts 112 in the circuit of the magnet 69, so that the transmitter and the selector mechanism cannot again operate until the elevator is returned to normal position. At the end of its stroke, the core of this magnet opens the contacts 97 in the locking circuit of relay 91, so that the control circuits'are all restored to normal condition, except that the energizing circuit of magnet 69 remains open as described, until the elevator 78 returns to its normal lowermost position ready to receive another line of matrices.

In the' standard line casting machine, the elevator 78 delivers the line to a horizontally moving carrier and the latter delivers it to the casting mechanism 120. To guard against the delivery of a line of matrices which is outside the casting range, that is to say, that is either too long or too short, means is provided iormeasuring the assembed line. For this purpose, it is controlled by a line measuring device and the latter is preferably arranged to measure the length of the assembled line and also the number of wedgeshaped space bands which, as is Well known and understood, are employed in the standard line casting machine to eifect the justification of the line.

As usual, tho assembling of the matrices 121 which are of fixed thickness, that is to say, each matrix is of uniform thickness, and the wedgeshaped space bands 122, which vary in thickness, effects the movement of an assembler slide 123 (see Fig. 11) which forms part of the standard line casting machine. In the present construction, this slide is provided with a depending lug 124 which is arranged to `engage a collar 125 on a rod 126. This rod is mounted in fixed

brackets

127 and 128 so that it is free to move longitudinally and also rotate. A spirally stepped cam 129 is fixed to one end of -the rod 126 and a spring 130 thereon normally presses the rod towards the right. The outer end of this. rod slides through the hub of a ratchet wheel 131 and a. spring-held dog 132 pivoted thereon engages a key way in the rod and so connects the ratchet and rod against relative rotation, but permits-the independent longitudinal movement of the rod. A spring 133 on the rod tends to rotate it and normally holds the dog 132 inengagement" with a fixed stop 134. l

Spring-held feeding and holding dogs 135 and 136 co-operate with the ratchet 131 and the former is pivoted on a rock arm 137 which is carried on a fixed pivot 138 and is connected by a link 139 to a lever 1`40. The latter and the usual space band lever 141 of the standard line casting machine, are both pivotally mounted upon a stud`142. An arm 143 on the lever 1401s connected by a spring 144 to an arm 145 on the lever 141 and this spring normally holds an extenslon on the arm 145 in engagement with the lower edge of the lever 140.

The lever 140 is connected at its outer end to the upper end of the space band reed 146, which is operated by the space key or by the selection and operation of a special lever 20 by the automatic control unit and in turn effects the operation of the

levers

140 and 141, so that the space band is delivered to the assembler slide and the rodor shaft 126 of the measuring device is rotated one step. The operation of'lever 140 requires a greater degree of motion than that of lever 141, and this is permitted by the yielding connection between these levers.

In addition to the step-by-step rotary movement of the measuring rod 126, it is shifted to the left by the engagement of the arm 124 on the assembler slide with the collar 125, Vsuch engagement being effected at a predetermined point in the assembling of a line of matrices.

The spirally stepped cam 129 co-operates with a. depending lug 147 on one arm 148 of a bellcrank pivoted at 149. The other arm 150 of this bell-crank has a pin and slot connection with a bell-crank lever 151 pivoted at 152. This lever is provided with a depending stop arm 153 which co-operates with

lugs

154 and 155 formed upon an offset 156 on the elevator 78;

In the particular form ofmeasuring device shown, the ratchet wheel 131 hasten teeth and the cam 129 is divided into ten divisions. The first division comprises a longitudinal slot extending throughout its length. The second division has a step the height of which when added to the thickness of the lug 147, equals the difference in thickness between the thin and thick ends of a space band. The second step on the cam has a height which when added to the thickness of 115 the projection 43, is equal to twice the difference between the thickness of the thick and thin ends of a space band, and so on for each step of the `cam, the height of each step of which exceeds the height of the preceding step by this diierence in thickness between the ends of a space band; that is to say, by the amount of possible justification which can be eiected by a single space band.

In the normal lowermost position of the elevator, the lug 147 is held in the position shown in Fig. 11 by the engagement ofthe stop arm 153 with the lug 154. The spirally stepped cam is variably positioned beneath the lug in accordance with the length of the line and also in accordance with the number of space bands in the line. Then, when the movement of the elevator is initiated, as described, the lug 154 thereon moves above the beveled end of the stop arm 153 and the latter can swing in clockwise direction to flower the arm 148 and lug 147. If the line is 135 within the casting range, the movement of the stop arm 153 will be arrested by the engagement of the lug 147 with the cam 129 as shown in Fig.

`8, and the continued movement of the elevator effects the delivery of the assembled line to the line casting mechanism and initiates such opera` tion. But if the line is either too short or too long, the lug 147 of the lever 148 will clear either the left-hand edge or the right-hand edge respectively of the cam, as `shown in Figs. 9 and 145 10, and the stop arm will engage the lug 155 and arrest the further vertical movement of the elevator. The amount of possible justification to bring 1a line to proper casting length depends, of course, upon the number` of wedge-shaped space 150 bands in the line, but the improved measuring arrangement makes provision for the possible justification by measuring not only the length of the line of assembled matrices, but also the number of space bands in the line.

Near the en'd of the upward movement of the elevator, the projection 156 thereon engages a lug 157 on a rock shaft 158. The holding dog 136 is fixed to this rock shaft so that this dog is thereby disengaged and a projection 159 on the holding dog also disengages the feed dog 135. Hence, spring 133 rotates the parts of the measuring device back to initial position with the dog or pawl 132 engaging the stop 134. The operation of the elevator also, of course, as usual restores the assembler slide 123,so that spring 130 restores rod 126 and the parts carried thereby to their right-hand position.

In case the elevator mechanism is arrested as described, the elevator magnet 103 will remain energized since its core does not complete its working stroke, and while it opens the switch 112v in the transmitter start-stop magnet 69, it will not open the locking circuit of.v the relay 91. Hence, the transmitter and the selecting mechanism controlled thereby will remain at rest and with the signal lamp 118 lighted, thus notifying the attendant that adjustment of the apparatus is required. The attendant may then adjust or reset the line. If he desires to reset the line, he can shift the handle '157a (see Fig. 3), thereby -opening the switch or key 113 andshifting the switch or key 95. The opening of key 113 prevents the re-starting of the controlling transmitter until the handle 157 is restored to normal. In either of its positions, key 95 will complete the locking circuit of the relay 91 at this point, but such circuit will be opened momentarily as the key passes from one position to'another to open this circuit and restore the controlling circuits to operative position until the relay 91 is again energized. The line vmay be reset manually by means of the keyboard of the composing machine, and then by manually operating the key 158 which is connected in shunt around the selector control switchr87, relay 91 can be energized to effect theoperation of the elevator mechanism in the manner previously described. The switches or

keys

95, 113 and 158 can be manipulated at any time, if desired, to stop the automatic transmission and permit the manual control of the composing machine.

A switch 115 (see Fig. 3) is in position to be engaged by the clutch member of a' standard line casting machine, which is shifted in case a matrix becomes jammed or misplaced in the distributing mechanism for the matrices. The shift of this switch will light the signal lamp 118 and arrest the operation of the controlling transmitter by opening the circuit of the magnet 69.

To prevent sparking at the contacts 50, condensers 159 are interposed in shunt around these contacts, Fig. 3it shows the circuit of the operating circuit for the transmitter motor. To insure the steady running of the motor, a governor is arranged to open and close contacts 160 connected in shunt around a resistance 161 in the motor circuit.

The line measuring device is also preferably provided with an additional cam 162 (see Fig. 20) on the longitudinally movable, rotatable rod 126. This cam is shaped like the cam 129, except that its edge is helical and 'is not stepped, and it is arranged to cooperate with a pair of contacts 163 in the circuit of a signal lamp 164, one of which contacts is provided with a ball-shaped projection 165. Cam 162 is adjustable and is so positioned that it will engage the projection 165, close the contacts and light the lamp, when four ems or other chosen amount can be added to the line of matrices to bring it to the minimum casting length. The attendant is thus notified when the line is about to attain its minimum casting length as is desirable, particularly when the composing machine is manually operated by the keyboard.

Different cams

129 and 162 are provided for different sizes of space bands. Since the amount of possible justification in any assembled line of matrices is determined by the number of space bands contained in it and since the rotary movement of the

cams

129 and 162 in effect measure the amount of possible justification, the signal lamp 164 controlled by the cam 162 indicates whether or not an assembled line is within the justifying range.

It is usual to have two embossings on veach matrix.- For example, one may be bold face and the other roman of the same character. Means are provided in hand operation for setting the matrices in either of two positions so that either character may be cast as desired.

Figures 22 and 23 show diagrammatically a signalk controlled means for doing this. On the elevator 78 is provided a sliding plate 166 upon which the matrices may rest as shown in Figure 22 and the matrix will be in the position to cast ordinary roman characters. However, if the plate 166 is pulled to the left as shown in Figure 23 the matrix will drop to a lower position, rest on shelf 167 and will be in position to cast bold face. Up to this point the operation is the same as in an ordinary hand operated machine. The lever 168 however, instead of being provided with a finger piece forhand operation is linked to the plunger 169 of a. double wound iron clad solenoid 170. This magnet is of a well known construction and if the right hand coil 171 is energized the plunger 169 will move to the right and the plate 116 will be moved to the left and bold face characters willbe cast. If the left hand coil 172 is energized the plunger 169 will move to the left and the plate 166 will be moved to the right and matrices set thereafter will cast roman face.

One terminal of each coil of the solenoid is, connected through a resistance to positive, the other terminal of the left hand coil is connected to contact 173, which is adapted to be engaged by a contact 174, connected to negative. The insulated tip of contact 174 engages the tip of lever 175, which is one of the levers 20 arranged to move the contact instead of tripping a matrix release. The other terminal of the right hand coil is connected to a contact 176 adapted'to engage a contact 177, connected to negative. Contact 177 is arranged to be operated by lever 178, similar toA lever 175, but responding to a different code setting of the permutation bars. It will be noted that this arrangement functions like a shift mechanism. If contact 173-174 is closed all of the characters thereafter will be roman face and if contact 176-177 is closed, bold face will be cast, until the condition is changed by the operation of the other contact.

The plate 166 on hand operated machine usually has the width of several matrices, #so that if l it is pulled out it will drop a considerable number of thepreceding matrices to the bold face position. To avoid this the face may be made quite narrow so that it will engage only one thick matrix or two thin ones. Since a bold face character or roman face character is usually preceded by a space matrix of some sort, sufficient margin may be obtained in this manner so that the position of the matrices can be governed as desired from the perforated tape.

Obviously, many changes can be made in the details set forth without departure from the scope of the appended claims.
