No. 37,289 Claims priority, application Germany Feb. 16, 1957 13 Claims. (Cl. 276-9) The present invention relates to type setting machines and is a continuation-impart of my copending application Serial No. 714,790, filed on February 12, 1958 for Type Setting Machines, now abandoned.

More particularly, the present invention relates to a Monotype machine wherein each of the lines is composed of a plurality of individual character castings which are arranged in groups to form the several words of the line, for example, and a plurality of space castings located between these groups to form the spaces between the words of the line.

The present invention deals particularly with the problem of providing in the lines space castings of a size which will give the line a final predetermined length. German Patents 262,554 and 502,621 as well as US. Patent 2,034,539 relate to this field. German Patent 502,621, in particular, discloses a structure which is capable of dividing the number of spaces between the words of a line into the difference between the final desired length of the line and the total length of the words of the line so as to determine the proper size for each of the space castings.

One of the objects of the present invention is to greatly simplify the structure for providing lines of the above style with space castings of the proper size.

Another object of the present invention is to provide a structure which will automatically locate space castings of the proper size in a line in a very rapid efficient manner which requires considerably less time than hitherto known solutions to the problem.

An additional object of the present invention is to provide a structure of the above type which is capable of using temporary space castings over and over again so that a special supply of a large number of such temporary space castings is not required.

A further object of the invention is to provide a fully automatic electric control arrangement for the means which shifts the character castings and the space castings during the setting of successive lines and during the transfer of completed lines.

, A concomitant object of the invention is to provide an electric control arrangement of the just outlined characteristics which does not require special actuating means but is set in operation whenever the operator depresses a selected key on the keyboard in the normal course of the operataion of the type setting machine.

With the above objects in View, the present invention includes a type setting machine comprising a support means having a pair of passages in which a pair of lines are guided for movement along the passages, and each of these lines is composed of a plurality of space castings located between the groups of character castings. One of these lines in one of the passages has temporary space castings located between the groups of character castings thereof, and the other line is guided along the other passage during the setting of this other line. In accordance with the present invention a means is provided for automatically transferring the temporary space castings from the first of these lines to the second line which is being set and replacing the temporary space castings of the first line with space castings of the desired size which will give the final line the desired total length which is required.

Each passage in the guide means is associated with a special guide means in the form of a chain drive and,

. contained in this particular line.

in accordance with a feature of my invention, the drive associated with that passage which receives a complete line while the next line is being assembled is adapted to be reversed either by a mechanical arrangement consisting of levers, links and friction wheels, or by a reversible electric motor. The reversing of this motor is brought about by electromagnetic means whose circuit includes a suitable switch means which is closed whenever the operator depresses a selected key of the type setting machine, i.e. that key which is depressed by the operator whenever the setting of a line is completed. The improved system further comprises a gate means which is located at the point where the two guide passages communicate with each other and which is mounted in such a way that it will yield to the line of characters and temporary space castings advancing from one of the passages into the other passage but will automatically return to its normal position in which it seals the passages from each other. This gate means controls a further switch means which acts as a circuit breaker and interrupts the circuit of the reversible motor whenever the first line is caused to advance from its respective passage into the other passage. Also, the circuit of the electric motor includes an additional interrupter switch means which opens the circuit and arrests the motor as soon as a temporary space casting enters a transfer plate which latter forms part of the means for transferring temporary space castings from the passage receiving a finished line into the passage in which the next line is being assembled.

The improved machine further comprises a system including a movable format stop member which is mounted on a toothed bar so as to advance therealong in stepwise fashion in such manner that the length of its steps equals the length of temporary space castings. This format stop member is advanced by a single step each time the operator presses a space key, i.e. a key which is depressed when a word is completed so as to introduce a temporary space casting into the passage in which a line is being assembled. When this stop member reaches a given end position which corresponds to the end of a line of predetermined length, it must be released so as to permit the associated chain drive to continue its advance and to move the just completed line into the other passage thereby enabling an operator to begin with the setting of a further line. The electric control system includes suitable electromagnetic means and switch means which automatically releases the movable format stop member whenever the operator depresses the line changer key of the machine.

A further feature of my invention resides in the provision of the aforementioned transfer plate in combination with a blocking plate the former of which brings about the transfer of temporary space castings from the passage receiving a completed line of castings into the passage in which a next line is being assembled, the temporary space castings becoming available owing to the fact that they are replaced by permanent space castings when an assembled line is transferred from the assembling passageinto the other passage. The means for reciprocating the transfer plate in a desired rhythm comprises suitable electro= magnets, and additional electromagnetic means is provided for conrtolling the counting mechanism which determines the width of permanent space castings by dividing the difference between the combined length of words in a just composed line and the desired length of this line by the number of spaces between the words Finally the improved electric control system also comprises electromagnetic means which adjusts the width of the mold cavity for the casting of permanent space castings, as well as additional electromagnetic means which arrests the casting wheel in a selected position above the mold cavity so that, when a selected key is depressed, the casting wheel will enable the machine to cast a selected letter or permanent space casting which is then introduced into one of the passages.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following detailed description of certain specific embodiments when read in connection with the accompanying drawings, in which:

FIG. 1 is a partly schematic, partly sectional elevational view of a machine including an electric control arrangement and embodying one form of my invention;

FIG. 2 is a sectional view on an enlarged scale taken along the line IIII of FIG. 1, as seen in the direction of the arrows;

FIG. 3 is a fragmentary sectional view on an enlarged scale taken along the line IIIIII of FIG, 1, as seen in the direction of the arrows;

FIG. 4 is a greatly enlarged fragmentary sectional view showing a detail of the structure shown in FIG. 1; and

FIG. 5 is a fragmentary partly elevational and partly sectional view of a mechanical control arrangement which may replace the electric control arrangement of FIG. 1.

Referring to FIG. 1, the machine includes a body or support means G provided with a pair of slide ways for a pair of slides D and L which are perpendicular to each other. The slide D forms part of the casting apparatus of the machine and the slide L serves to transfer the cast letters or spaces to other parts of the machine described below. When the operator presses the proper key, the slide D is moved to the left, as viewed in FIG. 1, by a distance which corresponds to the width of the letter or space which is to be cast. The distance of the slide D from the slide L determines the cross sectional configuration of the mold cavity. In the position of the slide D which is illustrated in FIG. 1, the mold cavity is completely closed, and this mold cavity is opened by movement of the slide D to the left, as viewed in FIG. 1. The setting of the slide D according to the width of the letter or space which is to be cast is well known, for example, in type setting machines of the Monotype class. When the space castings are formed, they are made in the same mold cavity and the slide D is set according to the size of the space castings. As was pointed out above, German Patent 502,621 shows a structure for automatically determining the proper size of the space castings by dividing the difference between the total length of the line and the total length of the words thereof by the number of spaces between the words of the line. Only the measuring feeler M of the mechanism for determining the proper size of the space castings is shown in FIG. 1, and this feeler M is supported for movement by the body G of the machine. The feeler M cooperates with a projection N of an ejector bar C guided for movement to the right and left, as viewed in FIG. 1, between the support means or body G and the carriage Sch of the machine which carries the finished lines of castings. FIG. 1 shows in dotted lines several positions which the projection N assumes when the ejector bar C is located in different positions.

To the left of the carriage Sch, as viewed in FIG. 1, the body G is formed with a pair of guide passages R and R which form a guide means for guiding a pair of the lines of castings for movement in the machine. A transfer plate U is guided for vertical movement, as viewed in FIG. 1, in a direction perpendicular to the passages R and R2.

As may be seen from FIG. 1, the ejector bar C is located at the elevation of and is aligned with the upper guide passage R and is guided for movement to the right and left through an upper cutout U of the transfer plate U which is also located at the elevation of the upper passage R so that the bar C is capable of moving through the cutout U of the transfer plate U into and out of the passage R The transfer plate U is provided with a second or lower cutout U" which, in the position of the parts shown in FIG. 1, is at the elevation of and aligned with the lower horizontal passage R and this second cutout U" of the transfer plate serves to receive a temporary space casting 11' which, as is described below, is exchanged for a permanent space casting. A plurality of these temporary space castings 11 are shown in the passage R just to the right of the motion transmitting element H which is connected with the sprocket chain of a drive B.

The passage R is aligned with a passage K of the carriage Sch. This passage K serves to receive the finished lines composed of the letter or character castings 6 indicated by the vertical cross hatching in FIG. 1 and the space castings 7 indicated by the horizontal cross hatching in FIG. 1. These space castings 7 are the final permanent space castings which are of the proper Width so as to give each of the lines the predetermined desired length. The passage K is limited at its top by a vertically movable guide Q and at its bottom by a horizontally movable guide R which moves in a direction prependicular to the plane of FIG. 1, as is particularly evident from FIG. 3, the guide Q moving up and down as viewed in FIGS. 1 and 3.

A blocking plate S is located just to the left of the transfer plate U, as viewed in FIG. 1, and is guided for vertical movement for a purpose described below, this plate S sliding along the left face of the plate U, as viewed in FIG. 1.

An endless sprocket chain drive A cooperates with the upper passage R This drive includes a first motion transmitting member ZA and a second motion transmitting member ZE which enters into the passage R during the operation of the machine, as will be described below. A horizontal toothed bar 0 is situated adjacent to and above the upper run of the chain drive A and carries a stationary first format stop member 0. This format stop member 0 may be releasably fixed at a selected position along the toothed bar 0 and once it is fixed in this position it remains therein until the format is changed, and the toothed bar slidably supports for movement therealong a movable second format stop member F8. The two stop members 0 and FS determine the format, or, in other words, the length of the lines. At the beginning of the type setting operation the movable format stop member FS is located next to and engages the stationary format stop member 0. Each time a space key is actuated by the operator, which is to say a key of the machine which forms a space between a pair of words of a line, the movable stop member FS moves along the toothed bar 0 through a distance of one tooth, and this movable stop member FS moves to the right away from the stationary stop member 0, as viewed in FIG. 1, each time such a space key is actuated by the operator.

A second endless sprocket chain drive B is located beneath the passage R The sprocket chain of this drive carries a pair of motion transmitting elements H and H The vertically movable guide Q of the carriage Sch is formed in its top face with a slideway for guiding a bar I for movement to the right and left, as viewed in FIG. 1, in a direction perpendicular to the plane of FIG. 3. At its right end, as viewed in FIG. 1, the guide member Q carries a stop Y which may be adjusted in accordance with the predetermined length of the lines which are to be formed and which cooperates with a contact in the electrical circuit of the control lamp L so that when the finished lines are fully located in the passage K, their engagement with the stop Y will cause the lamp L to be illuminated for indicating to the operator that a finished line has moved entirely into the passage K.

At its left end, as viewed in FIG. 1, the upper passage R; is inclined downwardly and communicates with the lower passage R and a gate W is located at the junction between these passages to permit the lines of castings to move downwardly from the passage R to the left, as viewed in FIG. 1, into the passage R and to prevent any of the castings from moving back up into the passage R from the passage R The gate W is turnably mounted adjacent its right end, as viewed in FIG. 1, for movement between the closed solid line position and the open dotted line position indicated in FIG. 1, and a suitable spring is coiled about the pivot shaft of the gate W and has its opposite ends connected to the body G and the gate W for resiliently urging the latter to the closed solid line position shown in FIG. 1. The movement of the line of castings from the passage R downwardly into the passage R automatically opens the gate W against the force of its closing spring.

The length of each of the teeth of the toothed bar which carries the stationary and movable stop members O and FS, respectively, is equal to the width of each of the temporary space castings 11, so that each time the movable stop member FS is released for movement, in a manner described below, it moves through a distance equal to the width of each of the temporary space castings 11.

The lower passage R extends to the left, as viewed in FIG. 1, beyond the left end of the passage R through a considerable distance, and in this passage R is located a stop E which is carried by a lever 17. This step E forms the eflfective left end of the passage R The passage R serves to guide a line of characters or letters 6 and temporary space castings 11 during the setting of the line, .while the passage R serves to guide a finished line composed of groups of character castings 6 which form words and temporary space castings 11 located between these groups, and, as will be pointed out below, these temporary spaced castings of the line in passage R are exchanged for permanent space castings 7 having the proper size. A supply of temporary space castings 11 is located between the motion trans mitting element H and the line of castings in the passage R and the first of the supply of temporary space castings 11 engages the motion transmitting element H on the chain drive B while the last of the supply of temporary space castings engages the first character casting 6 of the line in the passage R The drive for the sprocket chain assembly A is derived from the main motor of the machine which continuously rotates the pulley 12 through any suitable transmission. This pulley 12 transmits its rotation through a V-belt drive 120 to a friction wheel 13 which is in continuous frictional engagement with a second friction wheel 14 which is coaxial with and drives the left sprocket wheel A of the sprocket wheel drive A, as viewed in FIG. 1. When the motion transmitting member ZE is in engagement with the movable stop members FS, while the latter is not moving, the friction Wheel 13 slips with respect to the friction wheel 14. However, when this movable stopmember FS is released for movement along the toothed bar 0, then the friction wheel 14 turns so that the sprocket chain of the drive A turns in a clockwise direction to advance the motion transmitting member ZE to the right, as viewed in FIG. 1, until it is again stopped by the movable stop member FS. Thus, the sprocket chain drive A follows the movable stop member FS each time the latter is released for movement through a distance of one tooth when the operator presses a space key of the machine.

The sprocket chain drive B is operated by a motor M through a V-belt 19a which latter drives a friction wheel 20 coaxially mounted with the lefit-hand sprocket B of the drive B. The motor M is of the reversible type, and the direction of its rotation may be reversed by the aforementioned lever 17 which is controlled by an electromagnet M as well as by the stop E, the latter engageable by the last (leftmost) temporary space casting 11 in the passage R The lever 17 is pivotable about a pin 17' and its free upper end is anticulat-ely connected with a reverser b. This re erser b is connected in the armataure circuit of the motor M and, depending on its position, i.e. on the position of the lever 17, the reverser b causes the motor M to drive the friction wheel 20 in clockwise or anticlockwise direction. The circuit of the electromagnet M includes a switch a which may be closed by the space key of the machine, i.e. the coil of the electromagnet M receives current whenever the switch a is closed so as to withdraw its core and to thereby rock the lever 17 in clockwise direction whereby the reverser b reverses the motor M When the switch a is in closed position, the reverser b causes the motor M to drive the chain B in anticlockwise direction. The exciter circuit of the motor M also includes a disconnector switch 0 which is operatively connected with the gate W in such manner that it moves into open position whenever the gate W descends into the broken-line position in which it permits an advance of a line consisting of the letter castings 6 and temporary space castings 1.1 from the upper passage R into the lower passage R and toward the stop E. In other words, whenever the gate W is pivoted in anticlockwise direction, the circuit of the motor M is open and the chain drive B is brought to a halt. The purpose of such arrangement is to prevent a movement of the line consisting of letter castings 6 and temporary space castings ll]. in a direction to the right of the passage R before the passage R is completely evacuated. Such movements of the letter castings 6 and space castings 1 1 are caused by the stop E which is adapted to rock the lever 17 in anticlockwise direction (i.e. opposite to the action of the electromagnet M whereby the motor M drives the chain B in clockwise direction and the motion transmitting element H moves the line of letter castings 6 and space castings 11 in the passage R in a direction to the right. Since the motor M is arrested whenever the gate W is in its broken-line position, and since the chain drive A operates independently of the chain drive B, the former can evacuate the passage R of all letter castings 6 and space castings 111 before the drive B is started to rotate in clockwise direction.

The circuit of the motor M further includes an interrupter switch a which opens whenever a temporary space casting 11' enters the cutout U" of the transfer plate U. This is shown schematically in FIG. 4. As illustrated, the projection N of the bar I extends into the cutout U of the transfer plate U whenever the plate U assumes the position of FIG. 4. The projection N does not interfere with the transfer of letter-s from the passage R into the passage K of the carriage Sch. However, when a temporary space casting 11 enters the cutout U" of the transfer plate U, it strikes against the projection N and shifts the bar I against the bias of the return spring 40 in a direction to the right of FIG. 4 whereby the bar I displaces a resilient contact d which latter for-ms part of the interrupter switch a. This switch d then opens the circuit of and arrests the motor M The purpose of such arrangement is to maintain the freedom of movements of the transfer plate U, i.e. to protect this plate from pressure exerted by letter castings 6 and space castings 11 in the channel R The plates S and U are biased in downward direction by a pair of coil springs 54a, 60, respectively, and are in permanent engagement with a pair of coaxial cams 22 and 23 fixedly carried by the cam shaft 21. This cam shaft 21 is connected to the main drive of the machine in such a way that it is turned through a single revolution each time the space key of the machine is actuated by the operator. The cams 22, and 23 have such a configuration that they move the plates S and U, respectively, in a sequence which is described below.

The space key of the machine controls a switch i in the circuit of a relay M When this relay is energized,

7 it completes the circuit of an electromagnet M The core 22b of the circuit of an electromagnet M The core 221) of the electromagnet M constitutes a lock means for the shaft 21 by normally extending into a hole formed in a disc 22a carried by the shaft 21. Thus, when the operator depresses the space key of the machine, the switch i is closed to complete the circuit of the electromagnet M whereby the lat-ters coil withdraws the core 221) in a direction to the left of FIG. 1 and the shaft 21 is unlocked so that it may rotate with the earns 22 and 23. In other Words, the electromagnet M and the switch i control the movements of the transfer plate U.

The type setting machine also includes a rotary shaft 24 shown at the upper right of FIG. 1 which is rotatable by the main drive and is turned through two complete revolutions each time a space key is actuated by the operator. The shaft 24 carries a cam 25 which cooperates with the lever 26 for turning the latter about its upper pivotal support 27. The bottom end of the lever 26 engages a pin 28 which extends laterally from and is fixed to the ejector bar C. Therefore, each time a space key is actuated, the cam 25 will rotate through two revolutions to turn the lever 26 back and forth twice, so that this way the ejector bar C will move back and forth through two complete cycles of movement. This bar C is moved back and forth through one cycle in a known way after each of the letter castings 6 are cast and reach the space beneath the slide L ahead of the bar C, so that this bar C moves the letter castings 6 through the cutout U of the plate U, through the opening of the plate S, and into the channel R at the right-hand end of the line which is being set. The shaft 24 is caused to rotate whenever a temporary space casting 11 is introduced into the line of letter castings 6, i.e. whenever the space key of the machine is depressed. During each revolution of the cam 25, the lever 26 is rocked in clockwise direction about its pivot 27 to act against the pin 28 and to hereby shift the ejector bar C in a direction to the left.

The lever 26 is formed in two parts which are hingedly connected together at 29 and which are urged by a leaf spring 30 to the position shown in FiG. l where the lower part of the lever 26 forms an extension of the upper part of this same lever. When the ejector bar C encounters an obstruction, as described below, the lever 26 is capable of buckling at the connection 29 between its parts against the action of the spring 30 so that it will not break and will not move the ejector bar C beyond the obstruction. For example, the lever 26 will buckle at the connection 29 when the ejector bar C engages with a temporary space casting 11 which might become stuck in the transfer plate U, i.e. in the cutout U of this plate. In such instances, the distance covered by the ejector bar C is shorter than when this bar is caused to advance a temporary space casting 11 into the upper passage R The cam 25 is norm-ally locked and may be released to permit rotation of the shaft '24 by the action of an electromagnet M whose circuit may be completed by the aforementioned relay M i.e. whenever the relay M is energized, the circuit of the electromagnet M is completed and the transverse locking rod 25a which normally engages with the tooth 25b of the cam 25 is moved in upward direction (as seen in FIG. 1) to permit rotation of the shaft 24 and to permit the formation of a space casting in the well known manner. The relay M and the electromagn'et M control the ejector bar C.

I will now describe the arrangement which moves a complete line of letter castings 6 and space castings 11 onto the carriage Sch, which also moves the ejector bar C for determining the length of a line, which moves the completed line of letter castings and space castings into the passage R and which is also adopted to release the movable format stop member FS.

At the lower part of FIG. 1, there is shown a horizontal cam shaft 31. The main drive of the machine is operatively connected with this cam shaft 31 in such a way that the shaft 31 turns through a single revolution each time the line changing key of the machine is actuated by the operator. The cam shaft 31 carries a pair of cams 32 which cooperate with pivota'lly supported levers 33 (FIG. 3) for shifting the lower guide R of the passage K to the left and right, as viewed in FIG. 3, the levers 33 being connected with the guide R through pin and slot connections and being pivotally supported intermediate their ends, and suitable springs 33a cooperating with the levers 33 for maintaining their follower rollers 33!) in engagement with the pair of cams 32 which are carried by the cam shaft 31.

In addition, this cam shaft carries a cam 34 having a camming groove 34a coopenating with a pin 35c extending from a lever 35 which is pivotally supported at its bottom end 35a, as viewed in FIG. 1. When the end of a line has been reached, the turning of the cam 34 will cause the lever 35 to be turned between the solid and dotted line positions thereof shown in FIG. 1, and the top end of the lever 35 extends between a pair of pins 36 which are fixed to the ejector bar C at an extension 36a thereof which extends to the right beyond the projection N, so that the ejector bar C is capable of being moved with this construction independently of the lever 26. When the ejector bar C is moved due to rotation of the cam 34, it moves through a suflicient distance to determine the length of a line of letter castings and space castings and to thereupon locate the right end of the line set in the passage R beneath the axis of the right sprocket wheel A of the sprocket chain drive A, so that when the motion transmitting member ZE turns around its right sprocket wheel A" it will be capable of engaging the right end of the line in the passage R and moving the entire line down into the passage R as will be described below. A cable 37a is connected to the right end of the extension 36a on the ejector bar C and extends over a pulley 3t; and is connected at its free end to a weight 37 which guarantees that the ejector bar C is always urged to the right, as viewed in FIG. 1. This weight 37 guarantees proper cooperation between the pin 28 of the bar C with the lever 26 and between the follower pin 350 of the lever 35 with the camming groove 34a of the cam 34. It will be noted that the lever 35 is also constructed in two parts so that it is capable of buckling intermediate its ends when the ejector bar C encounters a resitsance, and a leaf spring 35b returns the lever 35 to the position shown in FIG. 1. The purpose of the lever 35 is to move the ejector bar C for measuring the length of a line and also to move this bar sufficiently in order to move the line of letter castings 6 and space castings 11 into the passage R The cam shaft 31 also carries a pair of cams 39 which respectively cooperate with a pair of follower rollers 39:: (see FIG. 3) carried by the upper guide Q of the passage K. After the cams 32 have been turned so as to advance the guide R to the left to the dotted line position shown in FIG. 3, the cams 39 are in such a position that springs 39!) which act on the guide Q are released to lower the guide Q so that the finished line of castings can be moved down on top of the previously finished lines, three of which are shown in FIGS. 1 and 3, and these finished lines advance downwardly along the carriage Sch to a position just beneath the guide R. When the just finished line has been lowered so that its top surface is located at the elevation of the bottom of the horizontally movable guide R the earns 39 return the guide Q to its upper position shown in FIGS. 1 and 3, and then the cams 32 return the guide R to the right to the solid line position thereof shown in FIG. 3 where it again cooperates with the guide Q to define the horizontal passage K.

When the guide Q is in its lower position determined by the cams 39, the bar I is at the elevation of the lower guide passage R and at this time the spring 40 which acts on the bar I to urge the latter to the left, as viewed in FIG. 1, moves the bar I to the left, so that all of the temporary space castings 11 which remain in the passage R are moved in this way to the left along the passage so that the chain drive B, which in the meantime has had its direction of movement reversed, is capable of having its motion transmitting element H engage all of the extra. supply of temporary space castings 11 to move the latter to the left beyond the gate W before the line of castings in the passage R is moved downwardly into the passage R The bar I fixedly carries a pin 59 which extends laterally therefrom, and the bar C pivotally carries a motion transmitting element 58 which is free to turn in a counterclockwise direction, as viewed in FIG. 1, but which cannot turn in a clockwise direction beyond the position shown in FIG. 1. When the bar I has been advanced to the left by the spring 40, the movement of the bar C to the left causes the motion transmitting element 58 to ride over the pin 59 so as to become located on the left side thereof, as viewed in FIG. 1, and then during the return movement of the ejector bar C, the motion transmitting element 58 engages the pin 59 so as to return the bar I to its rest position where it frees the guide Q for upward movement by the cams 39, the bar I being located just to the right of the plate U at this time, so that the plate U does not interfere with the upward movement of the guide Q. The guideway for the bar I which is formed in the guide Q has a lateral inclined surface, and the end face of the pin 59 also is inclined so that it is directed toward the right, as viewed in FIG. -1. This inclined end face of the pin 59 engages the lateral inclined surface of the guideway of the element Q so as to be retracted inwardly into the bar I to permit the motion transmitting element 58 to move past the pin 59, and thereafter a spring which acts on the pin 59 moves the latter outwardly to a position where it is capable of again cooperating with the element 58 the next time the line is changed. This spring moves the pin 59 outwardly to its operative position after the spring 40 returns the bar I to the left to the position shown in FIG. 1 where it engages the right face of the transfer plate U.

The release of the movable format stop member FS at the end of a line is brought about by an electromagnet M whose core 49a is connected to the left-hand end of a rockable lever 50 (see FIG. 1). The lever 50 is pivotable about a stationary pivot pin 49 and, when the coil of the electromagnet M attracts the core 49a, this lever acts against a spring pressed catch element 51 which latter normally engages with a tooth of the horizontal toothed bar If the lever 50 is rocked in clockwise direction, it disengages the catch element 51 from a selected tooth of the toothed bar 0' so that the format stop member FS may advance to the right under the action of the motion transmitting member ZE which is constantly urged in clockwise direction by the friction wheel 14. The circuit of the electromagnet M comprises a switch e which is closed when an operator depresses the line changing key of the machine. Thus, the line changing key, through the switch e and through the electromagnet M permits movement of the stop member FS out of the path of the chain drive A so that a line of castings set in the passage R may be transferred into the passage R As was mentioned above, the movable format stop member FS is released for movement through a distance of one tooth each time the space key of the machine is actuated, i.e. whenever a temporary space casting 11 enters the passage R This movement is controlled by the blocking plate S and is brought about through a lever system 55, 57. Whenever a space key is actuated, the

mold cavity for the casting of a space. wedge is adjusted in dependency on the width of the shaft 21 turns through one revolution, and the cam 22 acts on the blocking plate 5 to move the latter upwardly against the force of the spring 54a acting on the upper end thereof. This plate S carries a pair of pins 54 between which the right-hand end of the lever 55 is located, as viewed in FIG. 1, and the left-hand end of this lever 55 is supported for turning movement by a stationary pivot pin 56. Intermediate its ends, the lever 55 is pivotally connected with the rod 57. This rod 57 is composed of two sections which are interconnected with each other by a coil spring 57a which is stronger than the spring 51a which acts on the catch member 51 of the movable stop member FS. Thus, the ends of the coil spring 57a shown between the sections of the rod 57 in FIG. 1 are welded or otherwise fixed to the two sections of the rod 57 During the downward movement of the blocking plate S, the lever 55 will turn in a clockwise direction, as viewed in FIG. 1, so as to pull the rod 57 downwardly and to turn the lever '50 in a clockwise direction, as viewed in FIG. 1, in order to release the stop member F8 for movement to the right, as viewed in FIG. 1, through a distance of one tooth. The blocking plate S is moved in downward direction by its spring 54a whenever a temporary space casting 11 enters the passage R As the stop member FS moves to the right through a distance of one tooth under the action of the motion transmitting member ZE, the length of the inserted temporary space castings 11 is deducted from the length of the line whose overall length is being measured.

The above described construction of the rod 57 in two sections which are interconnected by the spring 57a permits the electromagnet M to turn the lever 50 while the blocking plate S remains stationary when the line changing key is actuated. The stepwise advance of the movable stop member FS to the right, as viewed in FIG. 1, each time the space key is actuated, enables the combined width of the temporary space castings 11 between the words of a line in the passage R to be deducted from the length of the line so that a determination of the proper size for the permanent space castings 7 may be made.

The motion transmitting element 58 which is pivotally carried by the ejector bar C and which has been described above is acted on by a suitable spring so that it is resiliently urged to the position shown in FIG. 1.

When the relay M is energized upon depression of the space key, it energizes a further electromagnet M whose function is to arrest the casting or matrix wheel of the machine in a selected position. As is known, the casting wheel rotates above the mold cavity and, when the electromagnet M is energized, it arrests the casting wheel in such position that a space casting may be formed in the mold cavity. For example, the electromagnet M may arrest the casting wheel by reciprocating a stop pin or the like. Similarly, each matrix of the casting wheel, i.e. each matrix which will produce a letter casting 6, is associated with its own stop pin which arrests the vcasting wheel in a predetermined position so that the corresponding matrix is located above the mold cavity of the form.

When the relay M is energized, i.e. when the space key closes the switch 1', this relay M completes the circuit of a further electromagnet M this latter electrm magnet is utilized for controlling the width of the mold cavity such as is necessary for the formation of a given letter casting or space casting. The mechanism for adjusting the mold cavity in such a way is well known in the art; for example, it may comprise a sensing element which is movable from a zero position along a stepped wedge for adjusting the mold cavity preparatory to the casting of letters, or along a stepless wedge to adjust the The stepped letter which is about to be cast so that the sensing element will move a given distance from its zero position. On the other hand, the stepless wedge is adjusted in dependency on the setting of the aforementioned dividing mechanism which divides the distance between the desired and actual length of a line by the number of spaces between the words in the line. The electromagnet M brings about a reversal of this sensing element from the position in which the sensing element cooperates with the stepped Wedge into the position in which the sensing element cooperates with the stepless wedge preparatory to the formation of a space casting.

Whenever the space key is depressed to close the switch 1' and to energize the relay M the latter also energizes an additional electromagnet M which is operatively connected with the counting means of the aforementioned dividing mechanism and causes the counting means to add a additional space casting to the number of space castings between the words in a line. In other words, the electromagnet M adds up the spaces between the Words. The circuit of this last mentioned electromagnet M includes an interrupter switch g which is positioned in such manner as to open in a fully automatic way shortly before the movable stop member FS reaches its end position. This switch g is positioned in the path of the first letter casting in the passage R and opens the circuit of the electromagnet M when engaged by the first letter casting. A signal lamp L lights up when the switch g opens. The just described arrangement insures that the temporary space castings 11 introduced after the lamp L is illuminated are not counted by the mechanism which is controlled by the electromagnet M Of course, in certain instances it becomes necessary that the counting mechanism should count temporary space castings 11 added after the movable stop member FS nearly reaches its end position, i.e. after the switch g is already opened by the first letter casting in the passage R For example, such additionally introduced space castings 11 must be counted if the end of a line contains one or more very short words or symbols which, however, must also be separated by space castings. In such instances, the operator depresses a special key, also located on the keyboard of the type setting machine, which closes a switch It which in turn shunts the interrupter switch g so that one or more additional space castings 11 may be counted by the counting mechanism.

If, at a certain stage of the operation, only temporary space castings 1 1 must be advanced by the apparatus without it being necessary to cast and to advance spaces of proper width, the operator depresses a special space key which closes a switch 1. This switch is connected in the circuit of a relay M whose movable armature controls the operation of aforementioned electromagnets M M M7, but not the electromagnet M which latter, as mentioned before, adjusts the mold cavity for the formation of a letter casting or space casting. The electromagnets M M M; are connected in parallel in the circuit of the armature of the relay M In setting of the first line, the operator depresses a selected key which corresponds to the first letter or symbol of this line. The mold cavity is then opened to a width corresponding to the width of the first letter, i.e. the slide D moves a given distance to the left and away from the slide L. When the casting of the first letter casting is completed, the letter slide L moves in upward direction, as viewed in FIG. 1, to a level above the level of the channel for the slide D, i.e. the slide D is then free to move to the right and to advance the first casting below the slide L. After such advance, i.e. after the slide D moves the first letter casting beneath the letter slide L, the latter returns to the position of FIG. 1 and moves the first letter casting into the path of the ejector bar C. Such operation is well known in the machines of the Monotype class. The ejector bar C then advances the first letter casting into the passage R by shifting the letter casting through the upper cutout U of the transfer plate U and to the left of the blocking plate S because the latter is then in the position of FIG. 1 in which its opening is aligned with the cutout U and, therefore, the plate S does not prevent the transfer of the first letter casting into said pasasge R The first letter casting is then brought to a halt at the left-hand side of the blocking plate S, as viewed in FIG. 1.

The operation is then repeated in the same manner until the casting of all letters of the first word is completed, and all such letters are transferred into the passage R to the left of the blocking plate S.

As soon as the casting of the letters forming the first word of a line is completed, the operator must depress the space key which closes the switch f so that the latter may complete the circuit of the relay M and that the cam 23 may shift the transfer plate U in upward direction, as viewed in FIG. 1. The temporary space casting 11' located in the lower cutout U of the plate U is then transferred into the position of alignment with the upper passage R As is clearly shown in FIG. 1, the temporary space casting 11 and the lower cutout U are normally aligned with the lower passage R The ejector bar C then transfers the upwardly shifted temporary space casting 11 to the left and into the passage R so that the temporary space casting 11' abuts against the last letter casting of the first Word in this passage. A permanent space casting 7 of proper width is not cast at this stage of the operation.

The distance between the motion transmitting members ZA (begin of a line) and ZE (end of a line) remains unchanged so that this distance determines the length of the first line. As shown, both these motion transmitting members are fixed to the chain drive A, and the member ZE trails the member ZA. During the setting of the first line, the motion transmitting member ZE remains in constant abutment with the movable format stop member FS which latter advances whenever a temporary space casting 11 is introduced into the passage R the distance by which the stop member FS is shifted always corresponding to the width of a temporary space casting. This is necessary because the combined width of all temporary space castings 11 in a line is computed when the setting of a line is completed and the combined width of the temporary space castings 11 must be deducted from the total line length. As explained before, the chain drive A is permanently urged to advance in clockwise direction because the continuously rotating friction wheel 13 is in permanent engagement with the friction wheel 14; therefore, the motion transmiting member ZE immediately follows any advance of the movable format stop member F8 in a direction to the right, as viewed in FIG. 1, and remains in constant abutment with this stop member.

Adjacent to the right-hand side of the motion transmitting member ZA, the chain drive A carries a turnable member or contact arm T whose nose is located beneath a contact rail forming part of a switch Z, the latter installedin the circuit of the aforementioned signal lamp L so that the latter lights up when the line formed in the upper passage R almost reaches its requisite length, i.e. when the first letter casting of the first word in the line received in the passage R comes into abutment with the downwardly extending nose of the turnable member T and pivots this member in clockwise direction so that the latter deflects the rail of the switch Z and completes the circuit of the signal lamp L The distance between the motion transmitting member ZA and the turnable member T equals the difference in the desired length of a line and the length of the nearly completed line at the time when the signal lamp L lights up. Simultaneously, either the first letter casting of the line in the channel R or the turnable member T opens the interrupter switch g of the counting mechanism (electromagnet M The turnable member T is constantly biased in anticlockwise 13 direction by a suitable spring which has its ends connected to this turnable member and to a link of the chain drive A, so that the member T normally extends into the upper passage R and into the path of the letter castings 6 therein. The lighting up of the signal lamp L indicates to the operator that the first line is about to be completed.

When the first line is assembled the operator presses the line changing key which releases the shaft 31 so that this shaft may complete a full revolution. The cams carried by the shaft 31 bring about the following sequence of steps:

(1) The ejector bar C is shifted by the lever 35 in a direction to the left, as viewed in FIG. 1, and thereby moves the first line in the passage R into abutment with the motion transmitting member ZA of the upper chain drive A. The lever 35 is rocked by the cam 34.

(2) The measuring feeler M then determines the difference between the actual length of the first line and also the desired length of this line, this difference corresponding to the spacing between the measuring feeler M in the position of FIG. 1 and the projection N of the ejector bar C. The result of such measuring operation is then conveyed to the counting mechanism in a manner well known in the art. This counting mechanism divides the just mentioned difference by the number of spaces between the words in the first line.

(3) In a subsequent step, the switch 2 in the circuit of the electromagnet M releases the catch element 51 because the electromagnet M rocks the lever 50 in clockwise direction. Thus, the chain drive A is now free to move with the motion transmitting member ZE and to advance the format stop member F8 in a direction to the right, as viewed in FIG. 1. The length of the toothed bar is selected in such a manner that the format stop member FS may be moved to the right of the right-hand sprocket A forming part of the chain drive A whereby the motion transmitting member ZE may bypass the movable format stop member PS while traveling about the right-hand sprocket A" of the drive A. As soon as the motion transmitting member ZE passes beneath the stop member PS, the latter is subjected to the action of a weight 52 and is returned in a direction to the left, as viewed in FIG. 1, back into abutment with the stationary format stop member 0. The weight 52 is suspended at one end of a cable 52a which travels about a deflecting roller 53 and has its other end connected with the movable format stop member PS. The inclination of teeth on the horizontal bar 0' and the configuration of the spring pressed catch element 51 is such that this catch element cannot prevent the stop member F8 from moving in a direction to the left, i.e. the catch member 51 then merely rides over the teeth of the bar 0'.

Since the chain drive A is now free to advance in clockwise direction, the ejection bar C can yield to the pressure exerted by the lever 35 (the latter then moving into its broken-line position of FIG. 1 because rocked by the cam 34) and the ejector bar advances the first line of castings 6 and 11 through and to the left of the passage R The length of the ejector bar C is selected in such a way that, when the lever 35 reaches its brokenline position, the left-hand end of the ejector bar moves beneath the vertical line passing through the axis of the right-hand sprocket A" of the chain drive A so that the continuously advancing motion transmitting member ZE engages the last letter casting 6 or the last space casting 11 in the pasage R and shifts the first line against the gate W which yields and permits the line to pass into the lower passage R and toward the stop E on the lever 17. As the gate W swings in anticlockwise direction into its broken-line position, it opens the switch 0 in the circuit of the reversible motor M so that this motor arrests the drive B.

In the meantime, the measuring feeler M has already released the projection N of the ejector bar C and, as

'14 soon as the position of the lever 35 permits it, the weight 37 draws the ejector bar back into the full-line position of FIG. 1.

(4) Simultaneously with the above described operations (1), (2) and (3), the cam 32 on the shaft 31 causes the lower guide R to move in a direction perpendicular to the plane of FIG. 1, that is, to the right of FIG. 3. The vertically movable guide Q is also displaced but in a plane parallel with the plane of FIG. 1 (in downward direction) so that it would normally move a completed line from the passage K onto the carriage Sch. However, the passage K does not as yet contain a complete line because the first complete line is still in the passage R The bar I which is guided in the movable guide Q (see FIG. 3) moves in a direction to the left, as viewed in FIG. 1, under the action of the spring 40 and thereby displaces the temporary space castings 11 longitudinally of the passage R a distance sufficient to move the castings 11 to the left of the vertical line passing through the axis of the right-hand sprocket B" of the chain drive B. The bar I is then returned to the right by the aforementioned motion transmitting element 58 as soon as the ejector bar C returns under the action of the weight 37.

(5) Simultaneously with the above described operations, the chain drive B begins to rotate in anticlockwise direction as soon as the electromagnet M is energized. The motion transmitting element H advances to the left, as Viewed in FIG. 1, and the second motion transmitting element H then shifts the temporary space castings 11 to left. As described under (4) above, these temporary space castings were moved to the left of the axis of the right-hand sprocket B of the chain drive B by the bar I which was shifted in the passage R in a direction to the left by its spring means 40. The first line which was advanced to the left of the gate W is arrested as soon as the motion transmitting member ZE passes in clockwise direction about the left hand sprocket A of the upper chain drive A. it will be noted that this left-hand sprocket A of the drive A is located to the left of the gate W so that the gate may return to its full line position as soon as the motion transmitting member 25 reaches the upper run of the drive A. The temporary space castings 11 advanced by the motion transmitting element H reach the stop E before the first line of castings and the first of these temporary space castings 11 causes the stop E to rock the lever 17 in anticlockwise direction so that the reverser b reverses the motor M (6) The motor M then reverses the direction of rotation of the chain drive B, i.e. this chain drive begins to rotate in clockwise direction, and the motion transmitting element H engages the first line and moves the same in a direction to the right and toward the passage K of the carriage Sch. The trailing motion transmitting element H engages the row of temporary space castings 11 and moves these castings in the pasage R until the rightmost temporary space casting 11f enters the lower cutout U" of the transfer plate U. As described hereinbefore, this temporary space casting 11 then causes the bar I to deflect the contact d and to open the interrupter switch d.

Referring now to FIG. 2, it will be noted that each of the chain drives A and B has a pair of coextensive chains. FIG. 2 shows the pair of motion transmitting members ZE as well as the pair of motion transmitting members ZA which form part of the upper chain drive A, and FIG. 2 also shows the motion transmitting element H and H of the lower chain drive B It will be noted from FIG 2 that the pairs of motion transmitting elements H and H are located nearer to each other than the pairs of motion transmitting members ZE and ZA Moreover, the configuration of the temporary space castings 11 is shown in FIG. 2. These castings are shorter than the character or letter castings '6, and shorter than the space between the pairs of motion transmitting members ZE and ZA. Thus, the motion transmitting members of the upper chain drive A do not in any way cooperate with 15 the temporary space castings 11. Furthermore, the lower motion transmitting elements H and H cooperate only with these temporary space castings 11.

It will also be noted that each of the temporary space castings 11 is provided at its right and left ends, as viewed in FIG. 2, with a pair of upper ribs 11a and a pair of lower ribs 110, and the passages R and R are formed with grooves which receive these ribs so that the temporary space castings 11 are guided in these grooves during their movement along the passages R and R It will furthermore be noted that the ribs 11a of the temporary space castings 11 extend above and below the character or letter castings 6 which are longer than the space castings 11. The permanent space castings 7 which form part of the final lines received by the carriage Sch have the same cross section as the character castings 6 and are not provided with any ribs.

The operator now proceeds with the setting of the second line. When, during the setting of the second line, the operator depresses the space key which closes the switch 1', the relay M becomes energized and, through the electromagnet M frees the shaft 21 for a complete revolution whereby a temporary space casting 11 which is located in the cutout U" moves in upward direction into alignment with the upper passage R and is advanced by the ejector bar C to the left of the blocking plate S in the manner as described above in connection with the setting of the first line. In the next step, the blocking plate S closes the passage R, as soon as the transfer plate U returns to the position of FIG. 1. In the meantime, the counting mechanism has adjusted the width of the casting form (magnet M so that a permanent space casting 7 of proper width may be cast in this form for the line which is already located in the passage R This permanent space casting is then advanced beneath the slide L in the manner as described above, and the slide L moves the permanent space casting into the path of the ejector bar C. The operation then proceeds in the same manner and the finished first line is transferred onto the carriage Sch when the guides Q and R are caused to move under the action of earns 32, 39, respectively.

Referring now to FIG. 5, there is shown a mechanical arrangement for operating the chain drive B and for releasing the spring pressed catch element 51 on the toothed bar The electromagnet M is replaced by a link train 45, 47, 48 and the motor M is replaced by a system of friction wheels and pulleys 15, 18, 19 adapted to rotate the friction wheel 20 and to advance the lower chain drive B in clockwise or anticlockwise directions. In fact, the entire electric control arrangement is omitted, including all the relays and all electromagnets. The tooth 25b on the cam 25 is not necessary because the arrangement of FIG. operates without the electromagnet M and without the transverse locking rod 25a.

In the embodiment of FIG. 5, the sprocket chain drive B is driven from a pulley 15 which is continuously rotated by the main motor of the machine (not shown) during the time that the machine operates. This pulley 15 rotates in a clockwise direction, as viewed in FIG. 5, and through a V-belt drive 15a it turns a friction wheel 18 which is rotatably carried by the lever 117 which is turnable about a pivot pin 16 which latter is fixedly carried by the machine. The lever 117 can be turned slightly from the position shown in FIG. 5 in a clockwise direction and then back to the position shown in FIG. 5, and any suitable means such as a hanging weight located above the pivot 16 or a snapover center spring is provided to maintain the lever 117 on one side or the other side of a vertical plane which includes the axis of the pivot pin 16, as viewed in FIG. 5. In the position of the parts shown in FIG. 5, the friction wheel 18 is in frictional engagement with a second friction wheel 19 which in turn is in frictional engagement with the aforementioned friction wheel 20 coaximly fixed to the left 16 sprocket wheel B of the chain drive B, so that in the position of the parts as shown in FIG. 5, the drive tends to turn the sprocket wheels B, B of the chain drive B in a clockwise direction in order to move the upper run of the sprocket chain of the drive B to the right, as viewed in FIG. 5, while when the lever 117 has been turned to the right, the friction wheel 18 will engage directly with the friction wheel 20 so as to reverse the direction of movement of the chain drive B.

The reversal in the direction of movement of the chain drive B is brought about in part by a cam 41 which is carried by the cam shaft 131 (corresponding to the cam shaft 31 of FIG. 1) and which turns with the latter when the line changing key is depressed. This cam 41 moves a push rod 42 upwardly, this push rod 42 being guided for up and down movement by suitable bearings 42a of the machine, and the push rod 42 acts on a lever 44 which is pivoted intermediate its ends at 43 to the right of the top end of the push rod 42, as viewed in FIG. 5. Thus, the cam 41 acts on the push rod 42 so as to turn the lever 44 in a clockwise direction, as viewed in FIG. 5. The left end of the lever 44 is located just beneath the top end of a bell crank 45 whose bottom end engages the lever 117. Thus, the upward movement of the push rod 42 causes the turning lever 44 to turn the bell crank 45 in a counterclockwise direction, as viewed in FIG. 5, so that the bottom of the bell crank will turn the lever 117 to the right, so as to place the friction wheel 18 in driving engagement with the friction wheel 20 and in this way reverse the direction of movement of the chain drive B.

The right end of the lever 44, as viewed in FIG. 5, overlies the left end of a lever 47 which is pivotally supported adjacent its right end, as viewed in FIG. 5, by a stationary pivot pin 46. Thus, whenever the lever 44 is turned in a clockwise direction by upward movement of the push rod 42, as was described above, the lever 47 will turn downwardly in a counter-clockwise direction, and a bar 48 which is pivotally connected at its top end to the lever 47 will also move downwardly. The bottom end of the bar .-8 engages the lever which corresponds to the lever 50 shown in FIG. 1 and which is pivotally supported adjacent its left end, as viewed in FIG. 5, by a stationary pivot pin 149. This lever 150 is located directly over the spring-pressed catch element 51 of the movable format stop member FS, and thus when the lever 150 is turned downwardly upon upward movement of the push rod 42, the springpressed catch 51 of the movable stop member FS is moved downwardly against the force of its spring 51a to release the stop member F5 for movement to the right, as viewed in FIG. 5. The friction wheel 13 now stops slipping with respect to the wheel 14 and rotates the latter so that the chain drive A acts on the movable stop member FS through the motion transmitting member ZE to shift the movable stop member FS all the way to the right of the toothed bar 0', and the motion transmitting member ZE now moves downwardly around the right sprocket wheel A" of the chain drive A so as to move out of engagement with the stop member FS and into engagement with the right end of the line of castings in the passage R this line of castings having been moved to the left, in the meantime, by the ejector bar C which at this time was actuated through the cam 34 to locate the right end of the line beneath the axis of the right sprocket wheel A" of the chain drive A. Thus, the movement of the motion transmitting member ZE downwardly to the lower run of the chain drive A enables this motion transmitting member to engage the line in the passage R and to move this line downwardly from the passage R past the gate W into the passage R and it will be noted that the member ZA is pivotally supported by the chain of the drive A in such a way that it is capable of moving beyond the movable format stop member FS without retarding in any way 17'- the-movement of the .chain. The motion transmitting member ZA shown in FIGS. 1' and 5 at the lower run of the. chain of the drive A cannot turn in a clockwise direction, as viewed in FIGS. 1 and 5, but is capable of turning in a counterclockwise direction, so that it simply moves past the movable stop member FS. As soon as the motion transmitting member ZE moves beyond the movable stop member PS, the weight 52 which acts through the cable 52a .guided' around the pulley '53 and connected to the stop member FS shifts the latter to the left up to and into abutment with the stationary stop member 0.

The machine of FIG. 1 combined Wih the mechanical arrangement of FIG. 5 operates as follows:

Whenever a key corresponding to a predetermined character is depressed, the slide D is moved to the left from the position shown in FIG. 1 through a distance corresponding to the width of the character or letter which is to be cast, and this character is then cast in a known way in the mold cavity referred to above. When the latter has been cast, the slide L moves upwardly to a position which locates its bottom end above thes-lideway of the slide D, and the latter then moves back to the right to the position shown in FIG. 1 so as to move the cast letter or other character into the slideway of the slide L which then moves downwardly so as to locate the character casting to the left ahead of the ejector bar C which now is moved in the previously described manner to the left to move the casting through the cutouts of the plates S and U into the guide passage R This operation of the ejector bar C was fully described hereinabove in connection with FIG. 1. The casting which has been moved by the bar C remains in the passage R to' the left of the blocking plate S, as viewed in FIG. 1.

In this way the successive letters of any desired word are cast and located in thepassage R At the end of the Word, again assuming that the first of a series of lines is being set, a special space key is actuated so as to cause the shaft 21 to rotate through a single revolution. The turning of'the shaft 21 causes the cam 23 to raise the transfer plate U. At this time a temporary space casting 11 is already located in the lower cutout U of the plate U, and the raising of the latter causes this lower cutout U" to become-aligned with the passage R so that the ejector bar C which now moves to the left, moves this temporary space casting 11 into the passage R at the end of the word. In this way all of the words and spaces of the first line maybe set, and the castings which form the first line are located in this way in the passage R It should be noted that at this time the lever 117 has the position shown in FIG. 5 so that the upper run of the chain drive B is urged to move to the right through the friction drive 18, 19, 20. Thus, the motion trans mitting element H urges the entire supply of temporary space castings 11 to the right, and the right temporary space casting 11 of the series of castings is in this way located within the lower cutout U" of the transfer plate U when this plate is in the position shown in FIG. 1. The upper and lower ribs 11a of the temporary space casting which is in the cutout U of the plate U engage the left end faces of the guides Q and R which form the passage K, so that the motion transmitting element H cannot move the series of temporary space castings to the right beyond the plate U into the passage K. Thus, the upwardly moving plate U transfers the first of these castings 11 to the elevation Where it is engaged by the bar C to be moved into the passage R and then after the bar C is retracted the spring 60 urges the plate U back down to the position shown in FIG. 1 and-as soon as the lower cutout U of the plate U again becomes aligned with the passage R the wheels 19 and 20 stop slipping and the upper run of the chain B moves to the right through a distance sufficient to enable the element H to locate thenexttemporary space casting 1 1 in they lower cutout U" of the transfer plate U.

During the time that the first line is being formed and assembled in the upper passage R the apparatusdoes not form permanent space castings 7 of the proper size.

As described above, the motion transmitting members ZA in the upper passage R are always at the same linear distance along the sprocket chains from the motion transmitting members ZE, respectively, and these members ZA deter-mine the length of the line in the upper passage R The members ZE remain in engagement with the movable format stop member FS which steps to the right through a distance equal to the width of a temporary space casting 11 each time one of these temporary space castings is inserted into the line which is assembled in the passage R In this way, at the end of the formation of the line the passage R the total width of all of these temporary space castings 11 may be deducted from the measured length of the line. The friction wheels 13 and 14 cooperate to cause the members ZE to follow the movable stop member FS.

As was already described above in connection with FIG. 1, the drive A carries a turnable member or con tact arm T which is located just ahead of the motion transmitting members ZA and which is capable of being turned in a clockwise direction, as viewed in FIG, 1, through the left character casting 6 of FIG. 1 in order to close the switch Z and to thus illuminate the lamp L when the line in the passage R is almost finished.. The movable contact of the switch Z is carried by the aforementioned springy member or rail which urges the turnable member T back to its rest position shown in FIG. 1, andthe line of castings turns the member T against. the force of this spring. The illumination of the lamp L shows the operator that the line which is being set is almost finished.

Whenthis line is finished the operator depresses th line changing key. This results in a single rotation of the shaft 131, as was pointed out above.

This turning of the shaft 131 again results in the performing of a number of operations. Thus, the turning cam 34 causes the bar C to move to the left so as to move the entire line. in the passage R into engagement with the motion transmitting member ZA. With the line of castings in this position the projection N is locatedat a predetermined distancefrom the feeler M, so that in this way the difference between the desired length of the line and the total length of the words of the line can be determined and so that the number of spaces between the words can be divided into this difference to determine the proper width for the permanent space castings 7 of the line. 7

Immediately after the distance between the elements M and N has been sensed to determine the proper width of the permanent space castings, the rotation of the cam 41 causes the lever to be turned so as to release the movable stop member FS, and now the chain drive A operates so that the motion transmittingmembers ZE turn around to the lower run of the drive and engage the right end of the line to continue the movement thereof to the left past the gate W down into the passage R5. The bar C has in the. meantimelocated the rightend of. the line beneath the axis of the right'sproc'ket wheel A',

of the chain drive A, so that the motion transmitting members ZE can engage the right end. of the line in order to continue the movement thereof. In other-words, the feeler M releases the projection N of the bar C, and then the cam 34 and lever 35 continue the movement of the bar C to the left so as to locate the right end 'of the line beneath the axis of the right sprocket wheel A'f, and then the members ZE cornearound and engage the right end of the line to continue the movement thereof. Now the bar C returns to its rest fluence of the weight 37. 7

Simultaneously with these operations, the lower guide position'under the in- R of the passage K has moved forwardly and the upper guide Q of this passage has moved downwardly to locate the bar I at the elevation of the lower passage R and at the same time the lever 117 has been turned to cause the direction of rotation of the sprocket wheels B, B of the chain drive B to be reversed, so that the motion transmitting element H moves to the left, as viewed in FIG. 1, and then the bar I is released to the force of the spring 40 so as to advance the entire supply of temporary space castings 11 which remain in the passage R to the left, as viewed in FIG. l. Thereafter the returning bar C causes element 58 to cooperate with pin 59 for returning the bar I into its guideway in the guide Q, and the latter is raised back to its rest position shown in FIG. 1. The movement of the chain drive B causes the motion transmitting element H at this time, to engage the right temporary space casting 11 of the supply of these castings in the passage R and to advance the entire supply to the left, as viewed in FIG. 1 or 5, beyond the gate W before the line of castings has moved up to this gate under the influence of the motion transmitting members ZE. Thus, when the line in the passage R moves down into the passage R the left end of this line becomes located to the right of the motion transmitting element H which is directed upwardly at this time.

It should be noted that the bar I when it is in alignment with the passage R moves the entire supply of temporary space castings 11 in this line to the left, as viewed in FIG. 1, to a position which locates the rightmost casting 11 over the axis of the right sprocket wheel B" of the chain drive B so that the motion transmitting elements H will engage the first of the series of temporary space castings 11 to transfer the entire group of space castings to the left, as viewed in FIG. 1 or 5.

Immediately after the entire line has been moved from the passage R down into the passage R the gate W closes automatically, and the motion transmitting members ZE turn around the left sprocket wheel A and move into engagement with the movable format stop member FS which is now located against the stationary format stop member 0.

In the meantime, the continued leftward movement of the supply of temporary space castings 11 causes the leftmost temporary space casting 11 to engage the stop E of the lever 117 so as to turn this lever 117 back to the position shown in FIG. 5, and now the direction of the drive B is again reversed so that the motion transmitting element H now moves to the right. It will be noted that the configuration of the motion transmitting elements H is such that they are capable of moving castings in either direction. Thus, these motion transmitting elements H engage the left end of the line which is now in the passage R and move the line to the right, as viewed in FIG. 1 or 5, and the motion transmitting elements H engage the leftmost temporary space casting 11 and move all of these space castings to the right behind the motion transmitting elements H During the further operation of the machine, these elements H turn around the right sprocket wheels B" of the chain drive B and become located at the lower run of the chain drive, in the position shown in FIG. 1.

Of course, after the motion transmitting elements H move down to the lower run of the chain drive B, the advancing of the line in the passage R is continued by the motion transmitting elements H The rightmost word of the line moves through the plates S and U and into the passage K, and this movement continues until the right temporary space casting 11 of the line in the passage R becomes located in the cutout U" of the transfer plate U. The ribs 11a of this temporary space casting engage with the guides Q and R, respectively, so that the advancing of the line in the lower passage R stops at this time and the wheels 19 and 20 slip with respect to each other. In this way the first of the temporary space castings of. the line becomes located in and remains in the lower cutout U of the transfer plate U.

Now the operator starts to form the second line, and the first word of this line is formed and becomes located in the upper guide passage R in the manner described above. When the operator actuates the space key for the first space of the second line, the shaft 21 will turn through one revolution and the cam 25 will turn through two revolutions. The sequence of operations is such that the transfer plate U first moves up to locate its lower cutout U" at the elevation of and in alignment with the passage R Now the bar C moves to the left and transfers the temporary space casting 11' to the left out of the cutout U of the plate U into the passage R at the end of the first word of the second line. The bar C now returns toward its rest position, and the blocking plate S moves up so as to close the lower cutout U" of the plate U which is still at the elevation of the upper passage R In the meantime the slide D has moved to the left through the proper distance for forming a permanaent space casting 7 of the proper width, and this permanent space casting is formed and is moved down into the passage ahead of the bar C by the slide L after the bar C returns from its first movement which locates the temporary space casting 11 in the line which is formed in the passage R Now with the permanent space casting 7 located just to the left of the bar C, the latter starts its second movement and moves this permanent space casting into the lower cutout U" of the plate U which is still at the elevation of the upper passage R Because a solid part of the blocking plate 5 is now located just to the left of and closes this lower cutout U of the plate U, the bar C cannot move the permanent space casting 7 to the left beyond the lower cutout U" of the plate U, and the lever 26 buckles at 29 at this time. Then when the cam 25 completes its second revolution the lever 35 returns the bar C to its rest position. Also, the plates S and U return to their lower position, and this movement locates the permanent space casting 7 in the lower cutout U" of the transfer plate U in the position in the line in the passage R formerly occupied by the temporary space casting 11', and because this permanent space casting does not have any upper or lower ribs, as soon as the transfer plate U has reached its lower position shown in FIG. 1, the chain drive B is capable of continuing the movement of the lower line into the passage K until the next temporary space casting 11 becomes located in the lower cutout U" of the plate U.

In this way each time the end of a word being set in the upper passage R is reached, and the operator depresses a space key, a temporary casting 11 from the lower line is moved up to be placed in the upper line and a permanent space casting 7 replaces this temporary casting 11 in the lower line. This process repeats itself each time the space key is depressed. I

When another line has been formed in the passage R and the full finished line in the passage R has been advanced this way into the passage K, the operator again depresses the line changing key so as to turn the shaft 131 through another complete revolution. The operator knows when the lower line of castings has been located completely in the passage K, since the. right end of this line will engage the stop Y to illuminate the lamp L in the above-described manner, so as to indicate to the operator that the entire lower line with proper permanent space castings 7 therein is located in the passage K.

Now when the line changing key is actuated, the above-described operations will be repeated, except that after the guide R moves forwardly, the downwardly moving guide Q will move the first line into a position beneath the guide R. Then the other operations described above take place, such as the release of the bar I to shift the remaining supply of temporary space castings 11 to the left, the continued movement of these castings to the left by the motion transmitting elements H, of the reversed chain drive B, and the movement of the sage R as well as thedetermination, before this move-.

ment of the line in the passage R down into the passage R of the proper size for the permanent space castings 7 of this line.

In the event that the line being formed in the passage R requires more spaces than the line already in the passage R then after this lower line is located in the passage K, the operator will note that while the lamp L has become illuminated, the lamp L has not become illuminated, and therefore the operator will not depress the line changing key, and instead he will press the space key each time he requires an additional space casting in the line which is being formed in the passage R and he will disconnect the structure for forming the permanent space castings, because no more are needed. At this time each of the successive temporary space castings 11 move into the cutout U" of the plate U in the same way as when the first line was being formed to be successively moved up into the line which is being formed in the passage R Assuming now that the upper line of castings requires less than the number of temporary space castings in the lower line, the lamp L will be illuminated before the lamp L and the operator will know that the lower line has not yet moved completely into the passage K, so that he will not operate the line changing key. In this case the operator presses the space key each time a successive temporary space casting 11' moves into the cutout U" of the transfer plate U, so that one or more of these temporary space castings will become located next to each other at the right end of the line in the upper passage R and of course permanent space castings of the proper size will be transferred down into the lower line in the manner described above. When the lamp L becomes illuminated, the operator knows that the lower line has moved completely into the passage K, and now he depresses the line changing key so as to turn the shaft 131 through one revolution.

It will be noted that in this case the extra temporary space castings 11 which are at the right end of the line in the passage R will not be transported by the motion transmitting members ZE down into the lower passage R because these members are spaced too far apart from each other to engage these extra temporary space castings, as is evident from FIG. 2, and as has been pointed out above. Therefore, these extra temporary space castings which happen to be in the upper passage R will remain therein and will become located ahead of the next line which is formed in the upper passage R It should be noted that these extra castings will simply move between the motion transmitting members ZA so that they do not in any way interfere with the proper measurement of the width of the permanent space castings 7 for the line. These extra castings simply move down into the passage R and become located at the right end of the series of extra temporary space castings. Y

Of course, when the second line of castings has become completely located within the passage K as well as when both of the lamps L and L are illuminated, so that the operator knows that the finished line in the passage K has all of the required permanent space castings 7 and that the line in the passage R has all of the required temporary space castings 11, the operator depresses the line changing key, and this second line is moved bythe element Q down onto the first line to become located just beneath the guide R which operates in the above-described manner to become located over the second finished line, and then the third and succeeding lines are formed in the above-described manner.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of type setting machines differing from the types described above.
