AUTOMATIC CONTROL FOR TYPESETTING MACHINES Karl Nause, Koln-Deutz, Germany Application February 24, 1959, Serial No. 795,111

. Claims priority, application Germany February 25, 1958 4 Claims. (Cl. 199-18) The present invention is concerned generally with typesetting machines and is more particularly directed to a device for controlling automatically released matrices in typesetting machines which is operated by means of punched tapes.

In previously disclosed devices control tapes used are punched by a perforator such as that disclosed in U.S. Patent 2,059,250. Perforators of the character involved generally comprise a conventional typewriter keyboard, punching means and counting mechanism. The counting mechanism generally includes a counting scale, a unit indicator to indicate the thickness of the matrix being employed, space band indicators and matrix frames with associated counting mechanism. The unit indicator is provided with pointers, the position of which indicating when a punched line ,is completed whereupon the completed line is justified and cast on the typesetting machine. A typical machine of the character involved is disclosed in US. Patent 2,091,286.

The tape utilized in previously disclosed typesetting machines had to be punched to the line width used, depending upon the size of the type required. In such an instance the dimensions are fixed at the time the tapes are punched and thus these tapes are limited to use only for the predetermined line width and size for which they were originally punched. When other line widths and type sizes are involved, the perforator had to be readjusted according to the new dimensions involved.

An object of this invention is to provide a device usable with a punched tape which is perforated according to the text and spacing in a continuous succession and which can be used in automatically operated typesetting machines without taking into consideration dimension changes resulting from the use of different type widths.

Generally in the prior art matrices are positioned one after the other in rows, the number of matrices per row and the size of the type being used determining the width of a line on a typesetting machine. The lines formed are justified by interpositioned space matrices and such space matrices are inserted in a line by manual operation of a space key. Hyphen matrices are also positioned in a line being composed by a manually operated hyphen key.

When using perforated tape with punches in continuous succession, there often occurs that a line will end in a completed word; however, a hole on the perforated tape after those completing the word will function to cause an unnecessary space matrix to be released. In order to eliminate the unnecessary release of such matrices, the present invention provides means functioning to prevent such release, this means functioning to prevent operation of the corresponding space matrix release bar of the machine.

The device of the invention affords the expedient of using previously punched tapes for use with various line widths and letter sizes. The device is specially desirable for use on automatic typesetting machines in relatively small printing establishments where there is a lim ited number of different type sizes and where the cost of a perforator or similar device is prohibitive.

Thus a further object of the invention comprises a device for the release of matrices in a typesetting ma-.

chine operated automatically by perforated tapes and includes meansfor operating a cam yoke, and means: for selectively preventing operation of the cam yoke;

and operation of a cam release bar.

Other objects and advantages of the invention will become apparent during the'course of the following (16 one preferred scription. In the drawing there is shown embodiment of the invention.

vertically spaced notches 4', 4". A trigger bell crank 5 is pivoted on a transverse shaft 5' and includes fai lower arm 5" terminally and pivotally engagedin the uppermost notch 4' of the bar 4. A lower notch .4 of the bar 4 receives the free end 2" of the key lever}, therein whereby the lever is disposed in a substantially The end 5' of the trigger bell: crank 5 pivotally supports one end 6 of a keyboard carni yoke 6', the other end 6" of this being pivotally sup horizontal position.

ported on a transverse pin 6", and thus the yoke 6' is normally disposed in a substantially horizontal position. The yoke 6 rotatably supports a cam 7 on a transverse pin 7' which is engageable with a transversely disposed, constantly rotating snatch roll 8. The cam 7 includes a radially extending stop9. The above mentioned structure is conventional.

Mounted above the cam yoke 6 is a vertically disposed solenoid including a reciprocable armature 10 and surrounding electromagnet 11. Upward movement of the end 6 of the cam yoke will engage the lower end of the matrix release bar and operate to release a matrix in the conventional manner.

Operation of the structure above is as follows:

A perforated tape will automatically move the key lever 2 counter-clockwise about 2' which will result in raising the dead weight bar 4 and accompanying counterclockwise rotation of the trigger bell crank 5. Movement of the crank in this manner results in pivoting of the yoke 6' clockwise about 6", permitting engagement between the earn 7 and roller 8. As the cam 7 rotates it will rise due to stop 9 engaging the snatch roll 8 causing the end 6 of the yoke to raise to operate the release bar 1. If the magnet 11 is energized, as will subsequently be described, the yoke 6' will be prevented from moving downwardly and the cam 7 will not engage the roller 8 and thus no matrix will be released at this time.

Referring to Fig. 2, there is disclosed an assembled slide which will function to control the energization of the magnet 11 and armature 10 to prevent the release of a matrix as mentioned above. Indicated at 12 is ,a

operation of a cam actuated cam yoke;

collector slide which includes electrical contact portions which will be engaged by a contact 13 during its normal or initial position of or with an adjustable spaced contact 14 at its final position toward which it is being moved. Suitable conducting leads L will connect the contacts 13 to the electromagnet 11. Contacts 14 will be connected by leads L to another electromagnet and matrix release mechanism (not shown). The slide 12 includes a stop or abutment 16,.a clapper 17, and a bell I8 engageable by the clapper shortly before the slide reaches its final position during movement. An adjustable abutment member 20 is provided in the path of movement of the abutment 16 and the assembler slide includes a projecting slide finger 19 and releasing lever 21. I

Operation of the assembler'slide is as follows:

When the assembler slide is in its initial position at the beginning of a sentence, and a perforation, on a continuous succession, control tape designatingan interwo'r'd-space or hyphen occurs on the tape, contact or the slide 12 With the contact 13 occurs and the magnet 11 is energized as in the position shown in Fig. l to prevent the release of a space or hyphen matrix. From its initial position, the slide 12 moves automatically toward the contact 14 according to each perforation in the control tape. When the slide engages the contact 14 which has been previously adjusted, this position being shown in. Fig. 2, another electromagnet (not shown) will be energized for the purpose mentioned.

In addition to the automatic energization of the magnet '11 to control operation of the yoke 6', the key 3 may be depressed manually if a control tape is not available. The invention contemplates the energization of the magnet 11 by specific combinations of perforations on the control tape so matrices other than those corresponding to spaces, for example, at the beginning and end of lines may be restrained.

One use oi the invention embodies the splitting up into syllables of vrnulti-syllable words on a perforated tape where each syllable is separated by a hyphen. The

' device'is arranged so that the perforation designating hyphens would result in holding the equivalent matrics back by magnetic means. Control or circuit-closing would be efiected by the assembler slide.

Where all multi-syllable words are connected by byphens, the text would have the following appearance, for example: The neu-tral punched tape will be produced When the tape is punched in this manner, the provision of interword spaces and hyphens" need no longer be carried out manually. The assembler slide -tially independent of manual operation and the neceswould function to eliminate hyphens at the ends of lines, this operation being prevented by energization by the electromagnet. As a result the transfer of signals or operation to the typesetting machine will be substan- 7 comprising a cam yoke, a matrix release bar engageable by said cam yoke in response to activation thereof by a signal transmitted by a perforated tape, and selectively operable cam yoke immobilizing means engageable with said cam yoke to prevent said cam yoke from activating said matrix release bar during predetermined increments of an operating tape.
