Description

Photographic Line Setting Machine The invention relates to a photographic line typesetting machine employing a hand-operated character keyboard with one the characters and the character widths as well as the Spatier. encrypting Device is coupled and in the case of a character emanating from this one of a typesetting plate each selecting a character for the exposure exposure Aperture system controlled and an optical system for linear photographic Playback of the characters selected one after the other on a relative to him moving film is initiated.

It is already known, the switching functions of a photographic To control line typesetting machine with a recording tape in the form of a punched tape. The use of such a perforated tape requires complicated mechanical ones Devices for punching and scanning information that do not increase the operating speed the photographic line setting machine over the upper one by the principle of the punched tape makes possible given step speed of the perforated tape.

However, since a photographic line typesetting machine is readily available in is able to carry out the setting process at a much higher speed, when it is controlled by the punched tape, the invention is based on the object a control unit for the switching functions of a photographic line-setting machine to create that the use of the machine with optimal working speed possible makes and at the same time with a significantly lower mechanical effort than so far, a quick storage of control characters and their equally quick implementation guaranteed in electrical impulses.

In another area of technology it is already known, a magnetic tape as storage and playback means for the control of mechanical processes and for To use triggering of switching operations. However, these facilities are on Photographic line typesetting machines not to be transferred, as such typesetting machines at the same time need a large number of control characters, which on the known magnetic tape system cannot be accommodated. The adaptation of such a magnetic tape storage to the special conditions when used for photographic line typesetting machines The invention is based on a further object.

These tasks are essentially achieved in that for one the characters for the choice of characters, character width as well as letter and line spacing absorbing and converting them into electrical impulses for photographic line setting Memory an indexable magnetic tape known per se is used on which a series of along a straight line transverse to the direction of travel of the tape in known Way arranged electromagnets when they are excited each have a magnetic point generate and that in a further parallel row of electromagnets each through a passing magnetized tape point causes a voltage pulse, and that the magnetic tape is indexable by pin rollers, each can be connected to a driving shaft by a magnetic coupling, and that a magnetically controlled stop device the magnetic tape in its advanced position stops and a switch disconnection of the magnetic coupling and the simultaneous Causes excitation of the stopping device.

This special embodiment of a magnetic tape memory for a photographic Line typesetting machine has the advantage that on the magnetic tape more Characters can be stored side by side in the cross direction than this at a perforated strip is the case with the one between the individual holes a certain distance must not be fallen below in the interest of the belt strength allowed. Furthermore, this also makes the magnetic tape particularly useful for control purposes of photographic line typesetting machines that it offers the possibility of erroneous characters, as they are easily and frequently found in the control of such machines happen to be eliminated easily by magnetic erasure and that in each case correct characters directly to the tape position occupied by the error character set. The magnetic tape also allows the control characters for entire lines and text parts with the help of an erasing magnet and reuse the freed sections for new strings of characters.

An advantageous development of the invention is that the the magnetic tape indexing pin rollers from an electric motor a slip clutch and a gear wheel that can be set in rotation by this, as well as still driven by a Maltese cross and the rotary movement of the gear automatically every time you type a character or a space one, when excited, the inhibiting effect of a swivel arm on the gearwheel by rotation of this arm lifting the electromagnet and releasing the gear for a moment is controlled.

To correct incorrect characters by deleting them on the magnetic tape the invention provides that the memory by one in the direction of travel of the magnetic tape following the pulse-forming electromagnets, the magnetic ones Tape points erasing and suitable for opposing magnetization of the tape permanent magnets and the rapid switching of the magnetic tape beyond this erasing magnet if an error is found in the line setting to delete the erroneous line can be brought about by pressing a delete key as well as the automatic introduction of a paragraph-by-paragraph using an end-of-line key Movement of the magnetic tape on the one immediately preceding the erasing magnet Electromagnet can be triggered.

Keypad and Encryption Mechanism The part of a photographic line setting machine designed according to the invention, which contains the keypad and encryption mechanism, consists of a device shown in FIG. 6 illustrated electric typewriter A, which has a main keypad A 1 with forty-two character keys a and with a strip-shaped space or space key a1 as well as a line end key a 2 and with several other finger keys required in typewriters of this particular type and also a next to the main keypad A 1 Auxiliary keypad A 2 with including the letter keys twelve keys a 3 and with a fill-in key a 4 and a delete key a5 and a code or encryption device B, which is provided directly under the keypads A 1 and A 2 and is in working relationship with them. Typewriter A is also equipped, as usual, with a paper trolley A 3, a platen A 4, characters A 5 and the other common parts, so that the printer always sees a copy of what has been written when the line is put together and so everyone in it can easily identify any errors that have occurred and need to be eliminated.

In order to achieve sufficient force and movement for the adjustment of the keypad and encryption mechanism, when the distance key a1 or a write key on the main or auxiliary keypad is depressed, the pivotable levers a6, on which these keys sit, individually by a linkage each in operative connection with rotatable cam disks a7, which rest against the surface of an elongated, continuously driven roller A 6 covered with a rubber coating, which supports the two key units A 1 and A 2 (cf.F i g. 2 and 6) is common. The cam disks a7 are rotatably mounted between and at the lower ends of the side walls of two-forked, spaced-apart supports A 7, which are provided in two rows of twenty-eight pieces along the front and the rear of the roller A 6. The carriers A 7 belonging to one or the other of these two rows hang from a rotatable rod a 8 common to them, which extends (see FIG only the twelve cam disks, which are required for the auxiliary keypad A 2, but also the forty-four cam disks required for the main keypad A 1 are pivotably held on the two rods a8.

The cam disks a7, of which those on one side of the drive roller A 6 (see FIG. 8) are offset from those on the other side of the roller, can back and forth when they are set in rotation by the roller A 6 Movable bars B 1 and B 2, which are arranged parallel to one another in a row and are directly combined with the keypad and encryption device B, move in opposite directions along their longitudinal axis. The bars B 1 and B 2, which are then individually in suitable holders B 3 are each provided with a tension spring b in compound which elastically b in its normal position of adjustable stop screws 1 and b 2 presses, of which the screws b 1 attack the rear ends of the strips B 1 and the screws b 2 on the front ends of the strips B 2. The displacement of the bars B 1 is achieved by overcoming the opposing force of their return springs b by rotating the front row of cam disks a7 controlled by keys, which act on rollers b 3 rotatably mounted on the bars B 1, and the displacement of the takes place in a similar manner Bars B 2 by the rotation of the rear row of cam disks a7 influenced by keys, which are in direct contact with rollers b 4 which are rotatably attached to bars B.

Between the parallel side walls of the forked cam plate carriers A 7 are not just the cam disks a7, but also these with the finger keys of the two key units A 1 and A 2 connecting rods stored by each of which according to FIG. 9 from a relatively small to a pin a10 pivotable angle lever a9 and from a horizontal one hingedly connected to this Lever a12 as well as one at one end to this and at the other end to the pivot lever a 6 vertical handlebar connected to the associated finger button. Of the shorter arm of the bell crank a9, as in F i g. 9 indicated in dashed lines is engaged with one end bifurcation of the lever a12, and the longer arm of the bell crank a9, which protrudes downward from the pivot a10, is unwound at its free end, so that it forms a stop shoulder a13 which is usually in the path of movement one or the other of two at diametrically opposite locations the one side surface of the corresponding cam plate a7 of protruding pins a14 engages.

In order to keep the cam disk a7 in its inoperative position, which is determined by the engagement of one of the pins a14 with the stop shoulder a13, the linkage acting on the cam disk also contains a spring-loaded finger a15, which also projects downward from the pivot a10 and with it a second pair of diametrically opposed pins a16 projecting from the same side of the cam disk a7 as the pins a14. A fixed horizontal stop rod a17 is used in each of the two rows of the cam disk carriers A 7 to hold them in their normal position according to FIG. 9 to be held by overcoming the opposing force of tension springs a18 acting on them, the cam disks a 7 being just out of contact with the surrounding surface of the continuously driven roller A 6. If, however, a finger key a is pressed, the pivot lever a6 will disengage the angle lever a9, which is articulated with it, for a moment from the currently active pin a14 of the cam disk a7, so that it frictionally touches the drive roller A 6 through the spring-loaded Finger a 15 can be pressed. As a result, the cam plate a7 opposite to the Uhrzeigerumlaufsinn (see FIG. F i g. 9) is rotated by the roller A 6, so that they b by appropriate action on the reel 4 the necessary longitudinal displacement of the associated reciprocable bar B 2 of the encryption device B backwards. The bar B 1 is moved forward in a similar manner when the associated cam disk a7 rotated by the roller A 6 engages the roller b 3 attached to it.

The encryption device also contains (cf. FIGS. 2, 3 and 8) two groups of elongated encryption bars 2 and 3 arranged at a mutual distance and a so-called universal bar 2a. All bars 2, 3 and 2 a are positioned immediately below the sliding bars B 1 and B 2 and the typewriter A extending in the longitudinal direction over practically the whole length. The rear encryption strips 2, six in number, are intended for character identification and, as shown schematically in FIG. 8 indicated, individually suspended on separate horizontal pivot shafts 4 by means of arms 5 extending therefrom. The rear encryption strips 2 have an L-shaped cross-section and have rows of tooth-like projections 6 on their upper edges and grooves 7 recessed between them, while the encryption strips 3, five in number, have a flat cross-section and are related to the character width stand and show short rows of tooth-like projections 8 and grooves 9 in between on their two longitudinal edges.

The front encryption strips 3, similar to the rear strips 2, are individually suspended on separate pivot shafts 10 by means of vertical arms 11, which, however, differ from the support arms 5 of the strips 2, engage in longitudinal slots 12 of the strips 3 so that they extend together in their longitudinal direction and according to one of five different positions opposite the overlying bars B 1 and B 2 , which can be moved back and forth transversely to them, and in this way both the correct character width key for large and small letters in roman or cursive as well as the width key for can select narrow initial letters, etc. The strips B 1 and B 2 are shown in FIG. 8 on their lower edges also provided with tooth-like projections b 5, which are at such a distance from one another that they are usually in an operative relationship with the teeth 6 and 8 of the selected encryption strips 2 and 3. Therefore, when a character key is depressed on either of the two keypads A 1 and A 2, the bar B 1 and B 2 brought into effect by the encryption bars 2 and 3 will rotate the associated pivot shafts 4 and 10 in one direction or the other and thereby electrically bring about the correct key transfer for the desired character. For this purpose, each of the shafts 4 and 10 carries at its right-most extreme end as shown in FIG. 8 a vertically arranged lever 13 fixedly connected to it between its ends and located next to a contact switch 14 which is usually open. The closure of the switches 14 is effected by one or the other of two pins 15 which protrude laterally from the opposite ends of the individual levers 13 and work independently of the respective direction of rotation of the shafts 4 and 10 . The encryption thus obtained for any selected character is then passed in electrical form from the switches 14 to the "memory" part of the machine which is to be stored.

The encryption bars 3 are mounted in a frame 16 which is easily removable from the machine for the purpose of replacement, in order, if desired, to change the encryption of the character width for texts of different sizes or printing. The universal bar 2a, although it is similar in shape to the encryption bars 2 and assigned to the group of these bars, does not have encryption grooves like these, so that they can be moved through all the character keys of the two keypads with the aid of the individual bars B 1 and B, which can be moved back and forth 2 can be brought into effect, which are provided with an additional tooth-like projection b 6 , which can grasp the bar 2 a near its upper edge. A separate pivot shaft 4a and several arms 5a depending from this hold the bar 2a in its normal position. A separate contact switch 14a is controlled by a the pivoting movement of the shaft 4 in a manner similar to the switch 14 through the shafts 4 and 10 by means of a lever provided with two pins in conjunction with the "memory" apparatus.

The common displacement of the five key coding strips 3 for the characters and out of their normal or the lower-case letter coding position is (see a bar 19 which can be displaced parallel to itself and which is elastically pressed against it by tension springs 20 and which is in connection with the free right-hand ends of the encryption bars 3 are in engagement. At its front end, the shaft 18 carries a handle provided with a dial 21 , by means of which it can be rotated, whereby it transfers the encryption strips 3 by overcoming the counterforce of the springs 20 from their normal position into their various other effective positions by means of the cam disks 17 , which are identified by the numbers 1 to 5 on the circular disk 21.

At its rear end, the shaft 18 extends far enough a console, not shown, which supports them, to three additional cam disks 22 to wear, which are attached to it at different angular positions and with corresponding different settings of the dial 21 optionally three electrical contacts 23 assigned to them can close. When big letters If there are double letters etc. in the imprint to be combined, the number disc becomes 21 adjusted accordingly in the correct position so that one or two of the contacts 23 come into effect to the character identification code assigned to these characters to complete. The dial 21 is arranged on the typewriter A, so that it is quickly available and easy to handle and those attached to it Makes yourself for relief their setting and resetting convenient let the printer read it.

When the strip-shaped spacer key a1 or the end-of-line key a2 or the fill-in key a4 or the delete key aS are depressed, the rotation of a cam disk a7 (cf.Fig. 2, 3, 4, 6, 7) causes special bars B 4 that can be moved back and forth and B 5 of the encryption device which are free of the tooth-like projections b 5 of the strips B 1 and B 2 parallel to them and can each directly adjust an electrical contact switch assigned to them. If, for example, the strip-shaped spacer key a1 is lowered, then one of the two strips B 4 with which it is located according to FIG. 3 and 6 is connected, moved forward from its stop screw b 1, overcoming the opposing force of its return spring b, so that it closes an electrical switch A 8 which is attached to the front of the support frame of the typewriter A. When the line end key a2 is pressed, the other of the two strips B 4 is moved forward in the same way in order to close a second contact switch A 9, which is also provided on the end face of the typewriter support frame.

Unlike the two bars B 4 that can be moved forward, the two bars B 5 can move backwards against the pulling action of their return springs b and away from their adjusting screws b2 in order to close one or the other of two electrical switches A 10 and All , which are connected to the back of the frame supporting the typewriter A are attached. As a result, the fill-in key a4, when pressed, can bring about both the rearward movement of the bar B 5 connected to it and the consequent closing of the switch A 10, and similarly, the delete key a5, when it is lowered, by means of the On the other bar B 5, close the electrical switch All. The buttons a 1, a2, a 4 and a 5 can energize separate relays by closing contacts, which in turn enable them to perform the individual functions intended for them when the machine is working through other electrical connections. Line display and remaining line measuring device When a line is set on the typewriter, an "information" or instruction from the five encryption bars 3 assigned to the character width as well as from the bar-shaped spacer key a1 is electrically transmitted by relays of a decryptor 24 (see FIG. 1) to an electromagnetic release device C, which (cf. FIG. 10) forms part of a line display mechanism which is connected to the typewriter. The patient key a1 of the keypad A 1 and the line end key a2 are electrically connected to other parts of this mechanism by separate relays.

According to FIG. 10, the triggering device C includes a drum C1, which are keyed onto a horizontal drive shaft C2 or otherwise attached to it and is slotted along its length so that it has a number of twenty-five Record rod-shaped slides c at the same distance from each other can, which (cf. FIG. 13) can be moved individually into and out of an operative position are. The drive of the slide c is by selective excitation of one or the other the other causes a series of twenty-four fixed electromechanicals C 3, which are arranged around the drum C 1 in a circle concentric to this and with their pivotable armatures cl in engagement with those protruding beyond the drum C1 Ends of a corresponding number of the slide c are available. While only eighteen such Electromagnets are necessary for most characters, which are a sentence width of less than 1, there are some characters - which have a larger one Be wide and measure up to twenty-four units, such as. B. the ligatures "Ff (" and "ffi". The armatures cl of these index or indicator magnets C3 are below the action of tension springs c 2, which they press elastically against stop pins c 3, which are arranged at suitable distances from the magnetic cores.

When one of the magnets C3 is excited and the corresponding rod-shaped Slide c is adjusted by the magnet arm c 1, it is the opposite End of the slide c (see FIG. F i g. 13) far enough over the adjacent end of the Drum C 1 pushed out to touch a stationary stop c4 and so on forcibly stopping the drum C1 while it is being rotated by the drive shaft C2. At this moment the protruding end of the respective effective slide c are located immediately in front of the armature c5 of a single release magnet C4, which practically in synchronism with the excitation of the next selected magnet C3 can operate so that it disengages the slide c locking the drum C1 brings with the stop c4 and moved back to its normal or starting position. The armature c5 of the tripping magnet C4 is just like the armature of the magnet C3 through a tension spring c6 (see FIG. 10) controlled and elastically attached to a stop pin c7 pressed at the correct distance from the core of its magnet. To this Wise is the "information" that is passed through the keypad encryption device B has been sent for the different character widths and the "information", which by the three units as the minimum word spacing determining strip-shaped Spatientaste a 1 has been released, converted into partial shaft rotations, which can be used to make the line display mechanism work.

The drive shaft C 2 receives according to FIG. 10 its movement from an electric motor C 5 through the intermediary of a slip clutch C 6 and is provided at its free end with a gear 25, through which it transmits its partial rotations to a guide screw C 7, the spindle c8 of which extends over one of its support and bearing stands 26 extends out and is connected to an arm c 9 and to a pinion c 10, which continuously meshes with the gear 25 and is thicker than usual for a motion transmission. The display mechanism also comprises a scale bar C 8, which is divided into one and en marks, which can preferably be read from right to left, and also a line length pointer c 11, which is displaceable along the scale bar C 8 by the partial turns of the screw C7 and thereby indicates the length of a line in a composition. The pointer c11 is attached to a support block C 9 which is arranged transversely to the lead screw C 7 so that it can be raised and lowered and thereby brought out of and threadedly engaged with the screw C 7. For this purpose, the block C 9 is shown in FIG. 10 slidable on the rod 27 penetrating it, which forms a bracket 28 with side arms 29 extending from its ends, which is connected to a horizontal pivot shaft 30 parallel to a rod 27, which is guided in bearings of the machine frame. The lifting of the pointer block C 9 takes place by overcoming the opposing force of two tension springs 31 , which are connected to the side arms 29 of the swivel bracket 28 and this in its normal position on vertically adjustable screws 32 with precise alignment of the internal thread of the pointer block C9 with the external thread of the guide screw Hold C 7.

In order to bring the line length pointer c11 into any previously selected line start position, a stop nut C 10 is provided for the pointer support block C 9 (see FIG and at its one end a button or handle c13, by means of which it can be rotated in one direction or the other in order to be able to transfer the stop nut C10 into different positions. The nut C 10 is inevitably slidable on a horizontal guide rail 33 when it is adjusted for lines of different exclusion lengths, and carries an electrical contact switch 34, which is controlled by a protruding projection c14 of the pointer block C9 when this is in and out of its starting position the nut C 10 is moved.

These settings of the stop nut C10 are also made visible on the scale bar C 8 by a second pointer C15 which is connected to the nut and protrudes slightly over the back of the scale bar. In order to achieve the accuracy required for setting the nut C 10 in the various positions within the unit fractions of FIG. 1, the rotary knob c 13 of the threaded rod c 12 according to FIG. 10 and 14 provided on its outer side surface with eighteen grooves c16 distributed over its circumference and serving as marks. A spring-loaded pawl c17 serves to hold the button and thus the threaded rod elastically in various angular positions by engaging one or the other of these grooves. However, before the nut C 10 is adjusted, the support block C9 for the line length pointer c 10 must be manually disengaged from the lead screw C 7, which is then relieved of the block C 9 and a small axial displacement overcoming the counterforce of the compression spring c18 by a slightly stepped cam surface c19 which is formed on the inner side of the knob c13 and is in contact with an unillustrated roller at the adjacent end of the screw spindle c8.

A spring-loaded drum C 11, which is connected to the pointer block C9 by a flexible band or cable c20, constantly seeks to pull the block into its original position when a line is assembled and usually presses it resiliently against the stop nut C10. When this is correctly positioned, the pointer block C 9 can be moved back by hand along the crossbar 27 of its support bracket 28 until it is stopped by the nut C 10, whereupon it is lowered into engagement with the lead screw C 7. The previous axial adjustment of this screw by the stepped cam surface c19 of the knob c13 serves to secure and facilitate this engagement.

The line display device of FIG. 10 also contains a spacing pointer c21, which is arranged near the right end of the scale bar C 8 and each time the strip-shaped spacing key a1 is depressed, a line length pointer c11 can be adjusted in parts of 21/18. The distance pointer c21 is attached to an angled slide c12 which sits on the scale bar C 8. Its intermittent movements are caused by overcoming the opposing force of a tension spring c22 by a rotating solenoid C 13 by means of two pawls c 23 and c 24, which engage in a rack c25 on the slide c12. The pawl c23 is hinged to the free end of the spring-loaded arm c26 of the solenoid C 13 and is provided with a nose-like projection c27 which overlaps a similar projection c28 on the retaining pawl c24 so that the two pawls can be brought out of engagement with the rack c25 at the same time before the slide c 12 is adjusted by the associated spring c 22 .

The retaining pawl c24 is pivotable about a fixed pin and by a vertical link c29 to the arm c30 of a second rotating solenoid C14 connected. A weak tension spring c31 connected to the solenoid arm c30 is, holds the retaining pawl c24 elastically engaged with the rack c25. As a result of this arrangement, the strip-shaped space button a1 is so often when assembling one line is depressed, the solenoid C 13 is energized for a moment and moves the space pointer c21 step by step along the scale bar C 8 in the Direction of the approaching line length pointer c11 while the retaining pawl c24 the distance pointer against the force of the spring c22 in its various Switching positions secures.

When a line is completely set and brought to the correct exclusion length and the line pointer c 11 aligns with the distance pointer c23. covers or has passed it, the remaining distance between the line length pointer and a zero mark on the scale bar C 8 is measured electronically and then the solenoid C 1.4 is energized to lift the pawls c23 and c24 out of engagement with the rack c25, so that the Space pointer c21 can be returned to its original position by the tension spring c23. At the same or approximately the same point in time, various other operations to be performed by the line pointer mechanism are electrically or electromechanically effected in a predetermined sequence. Accordingly, a single pulse is emitted from an electrical voltage source 35, which is shown in FIG. 1 is indicated by the rectangle with the inscription »Schaltverzug«, transferred to the release magnet C4 of the release device C to allow the drum C 1 and also the drive shaft C 2 to run idle over a sufficient number of degrees to the arm e 9 of the spindle c 8 of the guide screw C 7 to swing out and to bring it into engagement with an angular stop member 36 (see FIG. 10) and thus inevitably to inhibit the rotation of the guide screw C 7 in its exact starting position.

In the meantime, however, the support block C 9 for the line length pointer c11 is first automatically raised against the force of the tension springs of the bracket 28 and disengaged from the thread of the guide screw C7 and then retracted along the crossbar 27 of the bracket 28 until it stops by the stop nut C 10 before it has been lowered to re-engage the thread of the lead screw C 7. The raising and lowering of the hand block C 9 at this point is achieved by first energizing and then energizing a third rotating solenoid C 15 having an arm c32 in engagement with an arm 37 projecting rearwardly from the pivot shaft 30 of the bracket 28 is switched off. The solenoid C15 is excited to raise the pointer block C 9 by closing a contact of a two-way switch 38 (see FIG. 11). The switching off of this solenoid by which the springs 31 of the bracket 28 is released for lowering pointer block C9 is caused when this (see:. F i g 10) abuts to the nut C 10 and the contact switch 34 in this by the Projection c14 of the pointer block is opened. This control of the two electrical switches 38 and 34 also results in the excitation and disconnection of the solenoid c 13 for the advancement of the distance indicator c21.

The angled stop member 36 for inhibiting the rotation of the guide screw C 7 is pivotably mounted between its ends and is usually supported by a tension spring 39 in a manner shown in FIG. 10 apparent ineffective position outside the path of movement of the arm e9 of the lead screw spindle c8 held. The transfer of the stop member 36 into its effective position is brought about by the arm c33 of a solenoid C16, the excitation of which is caused by the closure of the same contact of the two-way switch 38 and takes place shortly before the excitation of the solenoid C 15, so that the rotation of the guide screw C. 7 is inhibited in its correct angular or line starting position before the pointer block C 9 is disengaged therefrom.

According to the invention, the device, which effects the electronic measurement of the remainder of the line after the composition of a line to the exact exclusion length, according to FIG. 10, 11 and 12 a in their plane back and forth displaceable transparent grid plate D, which can move in a horizontal path in suitable guides 40 and is arranged immediately in front of a similar fixed grid plate D 1 so that it moves across this during its Back and forth movement moves. The two plates D and D 1 are latticed with vertical opaque marks d and dl, which are in the form of parallel stripes at a distance from one another selected on the basis of eighteen units, and are provided between a plate D movable in front of the reciprocating plate photoelectric cell D 2 and an incandescent lamp D 3 located behind the fixed plate D 1 . Usually, the plate D is resiliently pressed against a stop pin 41 by a tension spring d 2. The opaque marks d on this movable plate cover the transparent spaces between the opaque marks d 1 of the fixed plate D 1 , so that the escape of light rays from the lamp D 3 through the plate D is prevented.

The remainder of the line changes if the length of the combined line is changed or if the line length pointer c 11 coincides with or passes by the distance pointer c21. The line pointer c11 will then be in the exclusion zone or in the area between the advanced distance pointer c21 and a zero mark (not shown) on the scale bar C 8. This mark is given and determined by a fixed contact plate 42 (see FIGS. 10 and 11). When the back and forth displaceable grid plate D is in its inoperative position according to FIG. 10 assumes, an electrical switch D 4 attached to it will come to cooperate with this contact plate 42. A second control contact for the switch D 4 is given by the protruding flange or projection c 14 of the support block C 9 of the line length pointer c11 when it stops in the exclusion zone. The operation of the reciprocating grid plate D is controlled by a rotating solenoid D 5 which carries an upright arm d 3 provided with a roller d 4 which engages with a downward projection d 5 of the grid plate D can come.

When a line is completely set and the line end key a 2 (cf. FIG. 6) is pressed, the solenoid D 5 is excited by a so-called auxiliary line end relay 43, which is shown in the circuit diagram in FIG. 1 is indicated in the upper half by an elongated rectangle and causes the grid plate D to its effective stroke. When this starts moving, the switch D 4 at the leading end of the plate (cf. FIGS. 10 and 11) is closed for a moment by the first through contact generator 42 in order to first sensitize the photoelectric cell D 2 and then a To direct a large number of light beams from the lamp D 3 through the grid plates D and D 1 to the cell D 2 until the switch D 4 is closed again for a moment when it meets the second through contact c14 .

The light beams conducted from the lamp D 3 to the photoelectric cell D 2 are converted by this into a corresponding number of electrical pulses - one for each unit measured - and these pulses are passed through a passage device 44 assigned to the remainder of the line (cf. i g. 1) transferred to a computer and finally used to exclude the set line. When the switch closes the second contactor c 14 , the photoelectric cell D 2 is desensitized so that a correct measurement of the remainder of the line is obtained, as determined by the number of electrical pulses generated in the cell. A resilient stop member 46 limits the effective stroke of the grid plate D. When the plate approaches this stop member, it can close a contact of the two-way main switch 38 , which then de-energizes the working solenoid D 5 for this plate and returns it to its normal position the locking pin 41 allows.

The exclusion calculator comprises (see FIG. 1) a step-by-step switch or space "adder" 47 which determines the total number of spaces or spaces between the words in a set line, and a "divider" 48 which determines the number of the electrical impulses of the photocell D 2 is divided by the number of word spaces, whereupon the "quotient" obtained is transmitted from the "divider" first to an exclusion memory device 49 and then through a passage device 50 assigned to the character width to a decryptor 51, where it is transmitted in a relay set is stored in code form to be ready for use whenever word spacing is to be provided during the photographic process. If it should happen by chance that one or more impulses remain as a fraction of the "quotient", then these are added one after the other to the impulses already used in the word spacing until they are exhausted. If, for example, there are five remaining pulses as a result of the calculation process, which represent, for example, an eighteenth of an one, they are distributed evenly over the first five word spaces in the compound line before it is photographed, as can be seen from the diagrams in FIG. 1 B, 1 C, 1 D can be seen. F i g. 1 B, a non-excluded line in the words u 1 and u 2 Minimalspatien therebetween. In F i g.1 C is shown a line from the words u 1, wherein the to the Minimalspatien u 2 already six Spatien u 6 Remaining lines are added. An excluded row is shown in FIG. 1 D, in which residual spaces are inserted in two places to completely exclude the line, so that there are seven spaces u7 in each of these places. The exclusion calculator is of the well-known binary type embodiment used in high-speed electronic calculating machines, so its further explanation does not appear necessary. Recording and triggering device F i g. Figure 15 shows schematically the recording or "memory" device and parts of the associated drive mechanism. This "memory" device temporarily stores character identification, character width and encrypted control information or control instruction on an endless magnetic tape E, and in doing so, this information is "written" across the width of the tape while it is at rest through a series of sixteen electromagnets E1, the so-called writing heads, are made, which are optionally selected according to any given character or space and, as mentioned, are intended to magnetize small, not shown, spot-like areas on the outer side of the tape. Of the sixteen magnets E1, the first nine are shown in FIG. 1 is assigned to the character identification and the next five to the character width, while of the last two the one with the strip-shaped spacer key a1 through a relay 52 and the other with the line end key a 2 through a relay 53 has an operational relationship.

The magnetic tape E is self-supporting and longitudinal its two side edges punched so that it is spaced with two at the ends provided with driving pins rollers E2 and E3 come into engagement can be operated independently of one another by separate electromechanical drives in Circulation are shifted, each of which in successive work cycles one both intermittent and rapid advancement of the belt E evokes. In this way, when the characters and the spaces of a line to be set on the typewriter A through optional lines Excitation of the electromagnets E1 are recorded, intermittently by a sixteenth Inches indexed through the pins of roller E2 until the line is completely set is. If the end-of-line key a2 is then pressed, rapid switching is possible of the tape E by the roller E2 due to the energization of the relay 54 by the relay 53 (see Fig. 1) brought about the following free section of the volume E in the correct starting position near the "writing" magnets El bring where he's ready to record for a second line that is set by the buttons.

Immediately afterwards the one bearing the first "written" line becomes Section of the tape E, which is forming a loop at this point, quickly through the pins of the roller E3 moved a certain distance so that the line to the "reading"; Place of the recording and triggering device, where a second row of sixteen magnets E4, the so-called "readers", is fed before a second intermittent displacement of the tape E takes place through roller E3. The rapid advancement of volume E is shown in caused this point in time that a relay 55 (see FIG. F i g. 1) by the Line end relay 53 is energized, and the following intermittent switching of the tape E is initiated by pulses from a clock generator 56 and performed which one complete revolution for each of the generation of a Character serving duty cycle makes. These impulses are sequential triggered by a through relay 57, which is connected to the generator stands and from the relay 55 by an intermediate switch, not shown and a "reading" initiating relay 58 is controlled. Additional roles E5, which work together with the sprocket rollers, are used to guide the belt E provided. These additional rollers E5 that are in front and behind the drive rollers E2 and E3 are arranged in the running direction of the belt E, hold this permanently in engagement with the pins of the rollers E 2 and E 3 and lead the Band E with the formation of two continuously present oppositely directed loops, which include a length of tape long enough to provide a quick one as needed or slow indexing of the belt through one of the two rollers E2, To enable E3 to the exclusion of the others. During the second intermittent Forward movement of the tape E and, as it passes, the magnetic generated on it Recording on the row of "reading" magnets E4 are voltage pulses in this magnet induces which after amplification in the output section of the Machine to use. A strong permanent magnet E6 is according to F. i g. 15 directly above the roller E 3 and a little behind the row of magnets E4 arranged and serves to erase or remove all traces of speckled or punctiform Records on tape E after the completion of the second intermittent Band switching.

The drives for the two rollers E2 and E3 are the same in shape and mode of operation. Therefore, in FIG. 15 only the drive for the roller E 3 of the reading point is completely reproduced, since the illustration and explanation of this drive also provides a picture of the corresponding drive for the roller E2. The shafts E7 and E8 for the rollers E2 and E3 are rotated in a clockwise direction by shafts 59 which are separated on the same axis and which are connected to one end of the shaft E7 and E8 by a coupling 60 each. At their other ends extending beyond the rollers E 2 and E 3, the shafts E7 and E8 each have a pinion E9 which meshes with a gear 61 seated on a short shaft 62 so that the rotary movements of the shafts E7 and E8 are applied to the shafts 62 are transmitted, which are each provided with a cam disk 63, which can act on a double contact switch E10.

A Maltese cross E11 with eight radial slots e distributed over its circumference is inserted into the drive for each of the two rollers E2 and E3. One of these two Maltese crosses E11, which is not shown in FIG. 15 is used to cause the intermittent switching of the tape E to the "writing" magnet E1. The other Maltese cross has the task of causing the intermittent switching of the tape E on the row of "reading" magnets E4. The step-by-step movement of each of the two Maltese crosses E 11 is caused by a succession of complete revolutions of a gear 64 seated on a shaft 65, which is driven by a main shaft 66 through a small slot 167 via a slip clutch 68 and by means of a laterally from protruding pin 69 engages with each revolution in one of the radial slots e of the Maltese cross E11 and advances this by 45 °.

When the gear 64 has made one revolution, it is stopped by an arm E12 which protrudes upwardly from a pivot e1 and is provided at its upper end with a lip e2 which is usually in the path of a pin 70 which extends from the side surface of the gear 64 adjacent to the arm E12 protrudes. A tension spring e3 holds the arm E12 elastically in this position, from which a magnet E 13 pulls it backwards when it is excited. The excitation of the magnet E 13 is caused intermittently by electrical pulses which (see FIG. 1) emanate from the through relay 57, which is connected to the clock generator 56, while the excitation of the corresponding magnet, not shown, is in the drive for the roller E2, the intermittent closing of the electrical contact 14 a by means of the universal strip 2 a causes when a line is put together in the typewriter. The gradual rotation of the Maltese cross E 11 is brought about on the drive shaft 59 for the roller E3 or E2 by means of a set of gears 71 and a toothed clutch E14 which acts only in one direction, which is usually kept in engagement by spring loading and the shaft 59 can only be taken in one direction of rotation.

The drives of the two rollers E2 and E3 each contain a magnetic coupling E15 and a stopping device E16. The magnetic couplings E15 are attached to the drive shafts 59 for the rollers E2 and E3 and, when energized, can set these shafts in rotation at the correct speed in order to effect the rapid indexing of the tape E to the "writing" and "reading" point , while the stop devices E16 serve to forcibly inhibit this rotation of the drive shafts 59 and in this way fix the tape in the longitudinal direction in the correct position for the start of "writing" or in the correct position for the start of "reading" . The two magnetic clutches E15 each generally contain a drum e4 equipped with a coil, which sits loosely on the associated drive shaft 59, and two contact slip rings e 5 electrically connected to the drum coil, one attached to the drum e 4 and extending from the main shaft 66 Gear wheel e6 driven by a gear wheel set 72, a drive pulley e7 attached to gear wheel e6 and a further pulley e8 which is roped onto drive shaft 59 and produces a driving connection between coupling E15 and drive shaft 59 when the clutch coil is excited.

The spring-loaded driving half of the unidirectional toothed clutch E14 is disengaged from the driven half and allows it to slide past it when the shaft 59 starts up through the intermediary of the clutch E15 when the belt E starts to be rapidly indexed comes. The two magnetic couplings E15 for one or the other of the two rollers E 2 and E 3 are usually excited at the same time when the line end key a2 is pressed and the associated relay 53 (see FIG. 1) is excited. At this point in time the relay 53 can first close the circuit of the relay 54 which initiates the rapid switching of the tape E during "writing" and then a few seconds later it can energize the relay 55 which causes the fast switching of the belt E during "reading". Each of the two stopping devices E16 for inhibiting the rotation of the drive shafts 59 contains (see FIG. 15) only one electromagnet e 9 and an arm e10 which can be adjusted by this and which comes into engagement with a disk e II wedged onto the drive shaft 59 can, in which a straight radial locking edge e12 is cut out, which can work together with the arm e10. The two arms e10 of the two devices E16 are arranged in a plane practically at right angles to the plane of the shafts 59 and are individually articulated at one end to rotary spindles e13 which are located at a corresponding distance from the shafts 59 . Usually the arms e10 are elastically held by tension springs e14 in their inoperative position outside the path of movement of the disks e11. If, however, the magnets e 9 are excited, the arms e10 are swiveled upwards against the pulling action of their springs e14 and brought into the movement path of the disks e 11 , so that they inevitably inhibit the rotation of the shafts 59 and in this way the belt E new in the exact position for the beginning of "reading" and "writing".

If an error occurs while typing the line on the keypad, the corresponding recording on tape E can easily be deleted by pressing the delete key a5 , which then causes a deletion relay 73 (see FIG. 1) to be excited. As a result of the energization of this relay, the relay 58 initiating the "reading" is temporarily de-energized, while the end-of-line relay 53 is energized and can carry out the rest of the functions assigned to it. In addition, the extinguishing relay 73 energizes both the auxiliary row end relay 43 and the relay 74 on the extinguishing delay circuit, so that the working of the magnets e9 prevents the operation of two complete movement cycles of the belt E and at the same time prevents the disconnection of the magnetic clutches E15 for driving the rollers E2 and E3 will. The relay 74 then de-energizes itself.

If lines shorter than the selected length, such as B. at the end of paragraphs appearing lines are put together, the fill-in key a4 is used, which energizes a fill-in relay 75 when pressed, which (see. Fig. 1) in turn switches on a relay 76 for non-exclusion and minimum distance. As a result, the relay 76 operates the appropriate minimum spacing character so that when the character width relay 50 is turned on, the character is sent to the character width decryptor 51. Closing the circuit of relay 50 prevents the "information" from passing from exclusion memory 49 to decryptor 51 and is brought about by the grounding of certain contacts in this relay. The filler relay 75 also energizes the line end relay 53 so that it can perform its normal functions. When a character from the end-of-line recording on tape E is received by an amplifier relay 77, this sends out an electrical pulse by which the minimum distance relay 76 is switched to its idle state by means of the character width relay 50.

To complete the storage or "memory" device, is a set of common amplifiers, which are defined by the triangular blocks 78 a, 78 b, 78 c in fig. 1 and 1 A are shown, with the reading magnets E 4 connected to this device and can handle the small voltages induced in it convert into substantial electrical pulses to the various relays in the To put the output section of the machine into operation. In this way, the for the identification of any selected character - block 78a electrical impulses are transmitted to a decryptor 79, where they continue through amplified pulses emanating from certain commutator segments of generator 56 and four relays of a relay set to operate to control the exposure to produce the desired character by adjusting a diaphragm device F, which according to FIG. 16 is provided in the optical system of the machine.

At the same time, the small tensions created by the group of the »reading« magnets e4, which correspond to the character width - Block 78 b - are assigned, converted into electrical pulses after amplification and transmitted to the decryptor 51. Here are these impulses as well as the impulses for the identification of the characters again from certain previously selected commutator segments of the generator 56 are amplified so that they relays of a relay set in the decryptor to bring about the working control a device which triggers the film carriage and which is shown in FIG. 1 A through the block P is indicated.

Electrical pulses are generated in a similar manner - block 78 c - from the small tensions generated and reinforced by those of the strip-shaped Distance key a 1 assigned "reading" magnets E4 can be induced. These too Pulses are passed to the decryptor 51, where they also relay one trigger a separate sentence which, according to the word spacing, makes the work of the Control the film carriage triggering device identical in all respects to the tripping device C connected to the line display mechanism according to FIG. 10 is.

Reinforced electrical impulses, which are generated by the small voltages of the last "reading" magnet and are assigned to the end of line key a2, are, after further amplification, fed by impulses from the generator 56 to the decoder 51 and from there to the release device for the film carriage. When the relay 58 initiating the reading (cf. FIG. 1) is energized due to the depression of the line end key a2, it in turn switches on the relay 57, which is connected to the generator 56 and is at this point in time the relay 57 is able to remove the power from the end-of-line key a 2 as well as from the delete key a5 and fill key a4 during the reading cycle. Optical system The from the F i g. The diaphragm device shown in FIGS. 17 and 18 consists mainly of a set of sixteen rotatable, vertically arranged drum-shaped diaphragms F 1 and a corresponding set of similar horizontally lying diaphragms F 2, which are in operative relation to the diaphragms F 1, but are sufficiently distant therefrom so that a plate G can be inserted between the two sets of diaphragms, which, as shown in FIG. 21 is indicated, is provided with a group of transparent characters g, which are arranged in horizontal and vertical rows on an opaque background. At their opposite ends, the diaphragms in both sets F 1 and F2 are held in support plates F3 and F4 of the overall frame of the entire optical system, and longitudinal slots f 1 are recessed in their drum wall, which extend practically over their full length, so that suitable Openings for the exposures as well as intermediate cover sections f 2 come into effect when the individual diaphragms are rotated by 90 ° in opposite directions. In order to prevent the passage of light coming from a mercury vapor lamp 80 past the diaphragm device F in the non-exposure periods, the diaphragm device also contains fixed shielding strips f 3 which are inserted between the diaphragms F 1 and F 2. When any pair of shutters, one in each of the two sets F1 and F2, are rotated to the open position to expose a preselected character on the typesetting plate G, light from the mercury vapor lamp 80 is sent to the space occupied by that character .

This turning of two selected diaphragms F1 and F2 is indicated by the simultaneous excitation of separate electromagnets f 4 achieved, which according to F i g. 17 are in communication with the diaphragms. The excitation of these magnets will caused by two electrical impulses, which each of these magnets in faster Sequence can be fed from the relay set of the decryptor 79. As from F i g. 19 and 20 is seen for the connection of the individual panels F1 and F2 with the armature f 8 of the associated magnet f 4 uses a linkage that has a contains reciprocating piston f 5, which is in tubular lugs f 6 of the Frame of the diaphragm device is guided and under 1Tovercoming the opposing force a compression spring f 7 through the pivotably mounted armature f 8 of the associated Magnet f 4, when excited, is moved towards its guide tube f 6. Like F i g. 17 shows the axes of the pistons f 5 are perpendicular to the plane of FIG Set plate G, preferably in one at the same time the axis of the associated diaphragm intersecting direction, and are connected to it by an off-center attacking direction Handlebar f 9 connected.

The arrangement is such that the excitation of a magnet f 4 by the first pulse emanating from the decoder 79 moves the armature f 8 of this magnet out of its normal position in which it (see FIG. 19) on a stop pin f 10 is present, in the in F i g. 20 apparent position is pivoted and the spring-loaded piston f 5 moves against the action of the spring f 7. As a result, the diaphragm in the direction of FIG. 20 drawn arrow through the handlebar f 9 beyond its dead center of movement from the in F i g. 19 to the position shown in FIG. 20 position shown rotated. When the magnet f 4 is switched off, on the other hand, the spring-loaded piston f 5 can complete the 90 ° rotation of the diaphragm in its open position, as shown in dashed lines in FIG. 20 is indicated. These operations are repeated with the second pulse coming from the decoder 90 , which will then again excite the magnet f 4, so that it rotates the drum-shaped diaphragm sufficiently far through the piston f 5 and the handlebar f 9 in the opposite direction that it resumes its normal position under the influence of the piston spring f 7.

The image of the character selected in this way on the character set plate G by means of the aperture device F is projected (see FIG. 16) by the converging lens system 81 to a collimation lens 82 of the optical system, whereby the light rays emanating from these characters are aligned practically parallel. These light rays then pass through a normal filter 83 and thence through two crossed diffraction gratings 84 which split the rays in such a way that both a single basic image and a plurality of higher order images are generated on a fixed cover screen 85 by means of a first image lens 86 which is connected upstream of the diffraction grating 84. In this way, a systematically ordered group of several hundred images of the same character can be generated and projected onto a flat recording field with the central image always in the correct position on the optical axis O of the lens system. The cover screen 85 is formed with an opening 85a which is in line with the optical axis O so that the single central image of the selected character on a film H can be photographed with the aid of a lens 87 which determines the final image or the point size .

The film H is held (see FIG. 22) in a carriage J which is intermittently movable in a horizontal plane transversely to the optical axis O, while the lens 87 is attached to a slide 88 which can be adjusted to various positions so that the distance of the lens 87 from the screen 85 can be selected longer or shorter; in order to be able to change the point size of the character on the film Hin as desired. To bring about the adjustment of the slide 88 carrying the lens 87 (cf. FIGS. 16 and 22), only a pinion 89 is required which meshes with a rack 882 on the underside of the slide 88 and through one in one direction or the other Handle or hand wheel 90 is rotatable. Film carriage and film operating mechanism As shown in FIG. 22, the film carriage J contains a U-shaped film holder J1, which is suspended by means of its side arms J2 and J3 on a fixed horizontal guide rail 91 and can slide along this during each photographic work cycle in order to guide the film H through the focal plane of the final image lens 87 and from there to bring it back to its normal starting position. The guide bar 91 is held at its ends on vertical uprights 92 and 93 of a support frame 94 , which in turn is supported in rails 95 of U-shaped cross-section extending from the front to the rear of the machine frame and is displaceable along this so that it can be displaced when the machine is being assembled can be brought into the correct and exact positional relationship to the optical system and to other neighboring machine parts. For this purpose, a shaft 97 is rotatably mounted and guided near its ends in the rails 95 and provided with two gear wheels 98 which are arranged not far from the rails 95 and mesh with corresponding toothed racks 99 which are attached to the base plates of the vertical uprights 92 and 93 are formed. The shaft 97 also carries a handwheel 97a, by means of which it can be rotated in one or the other direction in order to effect the adjustment of the frame 94 through the racks 99 and the gearwheels 98.

In order to prevent the film carriage J from shifting sideways and at the same time to secure it in an exactly vertical position during its displacement along the rod 91, it is provided with a roller j which hangs down from the transverse bar of the U-shaped film holder JI and between the Sidewalls a horizontal channel 96 of the support frame 94 is displaceable. The film carriage J further includes a Klenun device J4 for holding the film H and two film feed rollers J5 and J6 for the vertical downward displacement of the film by one line spacing after each exposure and after the carriage has been returned to its normal or leading position. One jaw j 1 of the clamping device J 4 is fixed, while the other or rear jaw j2 is seated on a pivot j 3 so that, in opposition to the pulling action of a spring j 4, it is out of contact with the film H prior to its downward movement by the drive rollers J5 and J6 can be swiveled.

This pivoting movement of the jaw j 2 is brought about by the excitation of a rotating solenoid J7, which has an arm j 5 which is suspended perpendicularly from its core and which at its free end engages a pin j 6 which is positioned above the pivot j 3 to the side of which protrudes from one of two end plates j 7 which are connected to the film clamping jaw j 2. In order to enable the exposure of the film during the intermittent advancement of the carriage J, the rear jaw j2 of the film clamping device J4 is provided with an oblong, oblong opening, not shown, through which the characters of a line are reproduced one after the other on the film during the composition when this is moved past the end image lens 87 . The upper part of the vertical piece of the film H in the vicinity of the carriage J is precisely guided by a horizontal transverse strip J 8 which starts from an angled, upwardly projecting extension j 8 of the film holder J1. The cross bar J8 also serves to carry a rotatable roller J 9 by means of an arm j 9 which supports a horizontal strip of the film and guides the film past the cross bar i to the clamping device J4 and the rollers J 5 and J 6 downwards.

According to FIG. 22, the two film drive rollers J 5 and J 6 are mounted in suitable support arms j 10 and j 11 of the film holder J 1. Their rotation, which advances the film, is caused by successive partial rotations of a horizontal shaft J 10 , which is rotatably guided in the vertical stand 93 of the frame 94 and is connected to one half j 12 of a coupling J 11, the other half j 13 on the shaft the front film guide roller J5 is keyed. If the carriage J approaches the line start position during its return movement, the two coupling parts j 12 and j13 can come into engagement with one another, so that the partial rotations of the shaft J 10 are transmitted to the roller J5 and furthermore to the other film guide roller J6 through two gears (not shown) while the carriage is momentarily stopped at the start of line position. In this way, the film H is moved down the correct distance for the line spacing and is held in readiness for the reception of the first character of the next line.

In the meantime, the solenoid J7 has been energized by the closure of contact k of a triple contact switch K to open the rear jaw j2 of the clamping device J4 in the manner described, thus releasing the film H from its downward movement caused by the rollers J5 and J6. When the contact k is closed, the other two contacts k 1 and k2 of the switch K are opened to allow the next advance of the film carriage J for character exposure. The opening and closing of the contacts k, k1 and k2 of the switch K is effected by means of a lip j14 which protrudes from the angled extension j 8 of the film holder J 1 and comes into engagement with a resilient actuator k3 of the switch K for the purpose of its adjustment when the film carriage J is gradually moved from its line start position. A pin j15 which protrudes laterally from the vertical leg J3 of the film holder J1 and directly faces a pad-like, on the upright 93 of the frame j 94 attached stop member 16 serves to fix the slide in its line start position.

The horizontal shaft J10 is given the necessary partial rotations according to FIG. 22 transmitted by the action of an electromagnetic release device L, which has a rotatable drum L 1 in a cage-like design, which sits on a horizontal shaft L2 and is driven by an electric motor M by means of a slip clutch M 1 . However, unlike the release device C of FIG. 1 connected to the line display mechanism, the device L has. 10 only a single indicating magnet L 3, and this can be set to different angular positions around the drum L 1 by means of a dial, not shown, whereby it can be caused to one or the other of z. B. twenty-five slides 1 to bring into effect, which are slidably guided in side by side in the circumferential surface of the drum L 1 recessed longitudinal slots. The magnet L3 can pivot a vertical arm L4 which is connected between its ends to a pivot pin 11 and which lies at its upper end directly opposite a selected slide 1. At its lower end, the arm L4 is connected to a tension spring 12 which usually presses it against a stop 13. If, however, the magnet L 3 is excited by closing the contact k of the line start switch K, the arm L 4 is pivoted by the magnet L 3 , so that it moves the slide 1 of the drum L 1 opposite it sufficiently far so that it can with a second Stop member 14 comes into engagement when a partial rotation of the drum L 1 is given by means of the slip clutch M 1.

At the same time, a magnet L5, which is fixedly arranged above the drum L 1, has been excited in a similar manner, so that it causes the drum to be triggered before it experiences a further partial rotation. For this purpose, an arm L 6 hanging down vertically from a pivot 15 is arranged in front of the tripping magnet L 5, so that it can be caused by this against the action of a tension spring 16, the slide 1, which was previously by the corresponding arm 14 of the display magnet L 3 has been selected to be brought out of engagement with the stop member 13 so that the drum L 1 can experience a further partial rotation of the same number of degrees by the motor M and the slip clutch M1. During the time in which the film carriage J is in its start position and the film clamping device J 4 is open, each partial rotation of the drum L 1 is transmitted to the horizontal shaft J10 and thence to the film feed rollers J5 and J6 by means of a keyed onto the drum shaft Pinion L 7 forwarded, which is in mesh with a larger gear J12 seated on the shaft J10. As a result, the film H is incrementally advanced by the appropriate distance for compliance with the line spacing, as is determined by the angular position which the previously set magnet L 3 and the associated parts with respect to the stop member L4 as well as with respect to the corresponding with occupy parts connected to the fixed magnet L 5.

As can be seen from the circuit diagram of FIG. 1 A can be seen, excited the closure of the contact k of the line start switch K by the film carriage J, if this is stopped in its line start or film advance position, first a so-called film control relay 100, which in turn is the rotating solenoid J7, the so-called movie surveillance solenoid, energized and then through a capacitance containing and with time delay effective electrical circuit also both Electromagnets Z, 3 and L5 of the line advance and release device L with current provides.

According to FIG. 22 and 24, the intermittent indexing of the film carriage J for characters and the word spacing is effected by a stationary spring-loaded drum 113 which is connected to the film holder J 1 by a tape or a belt J17. In order to control the advancing movements of the carriage J and then to bring it back into its starting position, a vertically arranged bar N is provided, which is hinged at its lower end to a slidable bracket N 1 (FIG. 24) and at its upper end with a finger-like extension N2 (Fig. 22) which is usually in contact with a pin J18 protruding forward from the film holder J1. Between its ends, the bar N is provided with a fairly extensive longitudinal slot n, in which a square stone h 1 can be displaced, which is attached to the free end part of a pin n 2 which protrudes forwards from a rack N3 and (cf.F i g. 22) protrudes through the slot in the bar N. The support bracket N1 for the swivel bar N can perform a reciprocating movement in a horizontal plane along two parallel, mutually spaced guide rods n3 in order to give the bar N a longitudinal movement relative to the square block n1 when performing its functions.

As a result, the leverage of the bar N will be constant and precisely control the intermittent advancing movements of the film carriage J, so that both the selected character width and the word spacing is always maintained regardless of the angular positions which the bar N will cause at these points in time. Furthermore, if it is desired to change the point size of the characters reproduced on the film H in the manner described, the intermittent movements of the carriage J and the bar N must also be changed according to the character width and the word spacing. For this purpose, the rack N3 is slidably guided in the machine frame so that it is adjustable in its longitudinal direction in order to bring the four-edged journal block n 1 to different heights of the longitudinal slot n of the bar N can. These adjustments of the rack N3 are easily carried out with the aid of a handwheel N4 placed on the front end of a pivot shaft N 5 and a pinion N6 wedged onto the rear end of the shaft N5 and a larger gear wheel meshing with both the pinion N 6 and the rack N3 N7 scored.

By turning the handwheel N4 clockwise, the pinion N6 can lift the rack N3 via the gearwheel N7 and move the journal block n1 upwards in the longitudinal slot n of the bar N, thereby reducing the movements of the film carriage J according to the character width and the word spacing. On the other hand, if the handwheel N 4 is turned in the opposite direction, the trunnion block n 1 is lowered in the slot n , so that the intermittent movements of the film carriage increase. As in Fig. 22 is indicated, the rack N3 is inclined at an angle which corresponds to the angle of the bar N when it has returned the film carriage J to its line start position. As a result, the setting of the journal block h 1 can expediently be achieved without interrupting a complete working cycle of the film carriage. A second spring-loaded drum 114 can also be used, which according to FIG. 24 engages by a band or a belt n4 on the bracket N 1 for this rod and supports the spring tension of the drum advancing the carriage.

F i g. 23 schematically shows the film carriage release device and the associated reset device as well as the associated gear and clutch mechanism. The release device for the film comprises a rod cage-like drum P which is keyed onto a pivot shaft P 1 which is driven by an electric motor P 2 via a slip clutch P3. Similar to that with the line display mechanism of FIG. 10 connected drum, the drum P is provided on its peripheral surface with parallel longitudinal slots so that it can accommodate a series of twenty-five rod-shaped slides p, which are evenly spaced from one another and which can be moved individually into and out of an operative position. The drive of the slide p is similar to that of the arrangement according to FIG. 10 is achieved by the selective excitation of one or the other of a series of twenty-four electromagnets P4 concentric about the axis of the drum and with their pivoting armatures p 1 engaged with the protruding ends of a corresponding number of slides. p stand. The armatures p 1 of these so-called display or index magnets are pressed elastically against stop pins p 3 by tension springs p 2 and are thereby held at a suitable distance from the magnet cores, for the adjustment of which they are provided.

Accordingly, when one of the magnets P 4 is excited, the slide p which is just cooperating with this is through the. Magnetic armature pl moved backwards sufficiently far beyond the drum P to engage with a fixed stop member p 4 when the drum rotates and so inevitably stop the drum in a corresponding angular position, which represents the total number of units around which the film carriage is to be switched on. At this point in time - the rear end of the inhibiting slide p will also come to lie directly in front of the arm p 5 of a single tripping magnet P 5 , which works practically in synchronism with the excitation of the next-selected magnet P4, so that this slide is disengaged forwards with the stop member p 4 and is pulled into its normal position and thus a further partial rotation of the drum P is possible. The arm p 5 of the release magnet P 5 is held by a tension spring p 6 elastically on a stop pin p 7 and at the correct distance from the core of the release magnet.

So that the partial rotations of the release drum P precisely determine the intermittent advancing movements of the film carriage J , the shaft P 1 of the drum P (see with this provided pivotable drive shaft Q 1 contains. The coupling 'Q consists of two halves p 1 and q 2 of which the former is keyed to the shaft Q 1 and the latter is connected to one side of a gear Q 2 which is rotatable on this shaft and also moves laterally on it under the action of a spinning solenoid Q 3 can perform. When the solenoid Q 3 is excited, it can move the gear Q 2 forward against the action of a compression spring 93 by means of a forked lever Q 4 and thus disconnect the clutch Q. Conversely, when the solenoid is de-energized again, the spring q 3 will push the gear Q 2 backwards and thereby close the clutch Q again. The excitation of the solenoid Q 3 is achieved by closing an electrical circuit which (cf.Fig.- I A) runs from the line-end relay 77 through a tooth clutch relay 101 , and this solenoid is switched off by opening the two usually closed Contacts k 1 and k 2 of switch K when the film carriage J is returned to its start-of-line position.

The gear Q 2 is set in rotation by an axially elongated pinion Q 5 , which is keyed to an intermediate shaft Q 6, which is driven by a shaft Q 7, which in turn is connected to the shaft P 1 of the release drum P by an elastic coupling Q 8 connected. The rotary movements of the drum shaft P 1 are transmitted to the shaft Q 6 by means of a relatively small gear q4 which is keyed onto the shaft Q 7 and meshes with a larger gear q 5 which is also attached to the shaft Q 7. In addition to its front end, the drive shaft Q 1 connected to the clutch is also provided with a pinion q 6 which, when the clutch q is closed for power transmission, rotates this drive shaft Q 1 partially by means of a larger gear Q 9 and a flexible shaft coupling q7 first on a cable drum R and then through a short piece of cable r on the movable support bracket N 1 of the slewing ledge N.

As shown in FIG. 23 as can be seen, the cable drum R is mounted on a pivot shaft R 1 , which is mounted on support arms of the machine frame and also carries a pulley R 2 and cooperates with a precisely acting inhibiting device R 3. In order to achieve the individual rotational adjustment of the drums R and R 2 with respect to the shaft R 1 and the jamming device R 3 when assembling the parts, each of the drums R and R 2 is provided with a concentrically slotted plate r 1 connected thereto and is keyed or otherwise attached to the shaft R 1. The indexing speed of the film carriage J can, if desired, be increased by a corresponding adjustment of the shaft Q 6 when the machine is at rest. This setting is carried out by means of a button or a handle q 8 and interrupts the engagement between the gears q4 and q5 and at the same time creates a drive engagement between two smaller additional gears q 9 and q10 , which are also located on the shafts Q 6 and Q 7.

When the tooth clutch is engaged, the partial rotations the trigger drum P, as indicated by the selective excitation of the electromagnet P4 can be made possible by the effective connections the intermittent Advance movements of the film carriage J under the influence of the spring-loaded drums Control J13 and J14. Then when the film carriage completes its forward movements and the line end relay 53 (see Fig. 1) is excited, the clutch Q is disconnected, to allow the film carriage to be returned to its start-of-line position. The latter process is achieved by an instantaneous closure of a friction clutch S causes which according to FIG. 23 is controlled by a rotatable solenoid S1 and sits on a shaft S2 which runs parallel to the pivot shaft R 1 and driven by an electric motor S3 through the intermediary of a coil spring S4 will. One half of the clutch S is connected to the drum by a belt s 1 R2 connected, and the other half s2 is immediately opposite the lower arm one vertical standing two-armed lever S5 provided, the connected between its ends to the shaft of the solenoid S 2.

A tension spring s3 maintains the lever S5 in its normal position against a stop s4, while the upper arm of the lever is in engagement with an electrical switch S6 associated with the solenoid S1. The arrangement is such that the solenoid S l, when the toothed clutch Q is released in the manner described, is excited by the clutch relay 101 (see FIG. 1 A) and brings about the engagement of the friction clutch S through the lever S5 . The intermediate shaft R 1 and the cable drum R are then due to the action of the elastic shaft coupling q2 by the pulley R 2 in opposite directions as shown in FIG. 23 arrows drawn in. As a result, the support bracket N1 for the slewing ledge N is pulled forward sufficiently far, overcoming the opposing force of the spring-loaded drums J13 and J14 of the film carriage J, in order to bring about the return of the carriage to its line start position, where it is in the correct position by the precisely acting jamming device R 3 is determined.

The purpose of closing the electric switch S6 by the lever S5 is to delay the cessation of energization of the solenoid S 1 somewhat in order to maintain the engagement of the friction clutch until the driving half q2 of the tooth clutch Q is fully engaged with the other half. Two diametrically opposed compression springs are arranged between the two halves s and s1 of the friction clutch S and ensure that the clutch is disconnected quickly and properly when the solenoid S1 is de-energized. The relay 101 is, as in the circuit diagram of FIG. 1 is indicated, excited by the line-end relay 53 via the amplifier 77, which in turn has switched off the relay 58 initiating the "reading" and also the through relay 57 in order to separate certain commutators of the clock generator 56 from the three amplifiers 78 a, 78 assigned to it b to separate 78 c.

As shown in FIG. 25 as can be seen, is the precisely working jamming device R 3 is immediately adjacent to the pulley R 2 and contains a rectangular block R4 which is threadedly engaged with the front end portion of the shaft R 1 stands so that it is movable backwards and forwards along this shaft when this rotated in opposite directions. The block R 4 of the jamming devices is slidable on a fixed support plate R 5 and at its front and back Backward movements precisely through a connection r2 consisting of tongue and groove out with this plate. When the shaft R 1 rotates clockwise by means of the pulley R 2 during the return movement of the film carriage J through the bar N - booster arm - is set in rotation, there is a backward displacement of the block R 4 longitudinally of the threaded part of the shaft R 1 instead, so that a stop finger r3, which of the rear side face of the block R4 protrudes into the path of a corresponding one Fingers r4 is brought, which protrudes forward from a disc R 6, which is attached to the one side surface of the belt drum R 2 is attached. If so, then the film carriage J arrives at the beginning of the line, the finger r4 can move against the inhibitor finger r3 and place the film carriage in its Define the line start position. On the other hand, if the shaft R 1 is in a clockwise direction of rotation is rotated in the opposite direction while intermittent indexing of the film carriage takes place under the control of the cable drum R, the fingers r 4 come out of engagement with finger r3 during the first revolution of this shaft and release this when the block R 4 of the blocking device R 3 due to his Threaded engagement with the shaft R1 for forward movement on its support plate R 5 is initiated.

In detail, the invention can also differ from the drawing Manner and includes e.g. B. also the use of a perforated tape instead of a magnetic tape for the encrypted transmissions or characters and also the separation of the compositional mechanism from the photographic one System that is particularly useful when using a perforated belt.
