invented new and useful Improvements in Type-Setting Machines, of which the fol-' lowing is a .specification.

The subject-matter of the present invention is improved means for canceling or eliminating .the action of incorrect groups of holes in register bands for setting type automatically.

;Means are known for making register bands for automatically operating type-setting machines, in which the register band is perforated by depressing keys and in which the text which is set is simultaneously written on a ty e-.Writer in order to make it ossible for t e composer to check his work.

urther, the arrangement of a special device, such as a key'or the like,.is known for punching a symbol inthe band after'an incorrectly written and perforated line, by means of which sym bol the group of holes representing the incorrect line-is made inoperative. In this manner the composer is able toeli'minate' errors in his work.

The present inventionv consists in a further improvement of these means, and an important object is to so simplify the work of the composer that a typist is able to make or pre are composition ready for printing.

In t e means known heretofore there are certain difficulties which are connected articularly with the justification of the lines. In order to obtain a good appearance of the matter, when setting type a the lines must be composed as full as possible. Conse- "quently the composer is frequently in doubt whether a syllable which is to be set can or cannot be got into the begun or nearly filled line. If he attempts to set up, the syllable in the line and recognizes, after he has begun,

that it is too long, in the case of the means known heretofore he had'to remove a whole line and set it again. Apart from the unnecessary loss of time which is caused, the danger that errors may occur in the composition is still more increased, since when the same text is written repeatedly, when the composer involuntary writes more rapidly thangenerally, errors very easily occur as experience shows. Also the removal of entire lines on account of one single error occasions unnecessary loss of time. An error occasioned by depressing the" wrong key is, as arule, quickly'recognized by the composer or typist, so that he can at once remove the error in so far as a suitable device is resent'for this.

11 order to remedy the above mentioned defects, according to the present invention besides the device forcanceling entirelines, a second device is arranged for canceling or eliminating the word last set up. For s ecial cases another device is also providbd which admits of individual characters or individual symbols on the register band being- Inade inoperative. This device is of special importance because there are provided on the a paratus for perforating the band, in

addition to the character keys, a series of keys, levers or the like for other purposes, for example for the end of a line, changing to another. sort of type, justifying the lines, and so on. These keys also may be used incorrectly. Since the depression of such a key causes a symbol to be perforated in the register band, the effect of these keys being used incorrectly would also be transferred to the type-setting machine. Therefore according to the present invention the concerned perforated s mbols are able to be made inoperative in ividually'.

IVhen removin or eliminating lines, words and indivi' ual characters by renderin inoperative the appertaining places of the reglster band special regard must be aid to justifying the lines, the device for indicating the space for the type having to be correctly set in each case. With regard to the line this is very simple, since after each admissible or inadmissible line the type-space indicator is brought into the position which it has to take up at the commencement of a line, which can take place automatically. When removing or eliminating individual words another device is required. Since the words are of different length, the composer must be able to know how long the last written word is andhow much the type-space indicator has to be moved backward when this word is removed. The same holds good when removing individual characters. For this instance the invention provides special means. These means substantially necessitate the employment of a typewriter with systematic movement of the paper carriage as type-space indicator, the word systematic here and hereinafter denoting: according. to types of difi'erent width. When each key is depressed the paper carriage is shifted a certain distance, corresponding to the breadth of the letter which" is written with the key and set up, but so however that the distance which the paper carriage is shifted is in a fixed proportion to the breadth of the printing letter which is to be set up. The same relation then of course also exists between the wordlengths of the written line and of the line which is to be composed later by means of the band. Now When removing or eliminating a word or a letter the paper carriage must be setbackward the length of the written word or individual character. It is preferable, when, removing a Word, to set the paper carriage backward and to perforate the symbol in the register band by which the word is removed, with the same lever or the same key. When one single character is being removed such a combination of the two actions can be dispensed with, because the carriage can be placed backward a small amount more simply with the aid of another device, and because the means for removing one single perforated symbol is used/less for removingcharacters than for removing the above mentioned auxiliarysymbols in the register band. In the latter case, however, it is not necessary to rectify the position of the paper carriage or type-space indicator.

For putting the invention into practice band perforating machines and typewriters of optional construction may be employed in so far as the latter are provided with means for shifting the paper carriage systematically, namely according to types of different width.

' In order that the invention may be clearly understood reference will be made to the accompanying drawings in which one embodiment is represented by way of example and in which a typewriter of known kind isshown in combination with a known device for perforating bands. When the keylevers of the typewriter are depressedelectric contacts are'closed and corresponding electromagnets of the perforating device are operated.

In the drawings: Figure 1 is, a vertical side elevation of the combined machine, part" of the frame of the machine being shown broken away Fig. 2 is a front elevation of- .means used for canceling entire words; Fig. 3 is a front elevation of means used for can celing entire lines, whereas Fig. 4 is a diagram of connections which'will be explained hereafter,- and Fig. 5 is adetail shownfin front elevation.

Referring to the drawings, the combined typewriter and perforating machine has, a

common body or frame 1 which carries in front the typewriting mechanisms This ter being attached to the body of the typewriter. The paper carriage is moved in known manner by a spring. For checking the movement of the carriage four ratchet wheels 21, 22, 23 and 24 are arranged. Each of these is connected with a bevel wheel 25. Each two bevel wheels 25 act on a planet wheel 26, the pivots of which are attached on a bush or sleeve 27 revoluble freely around the axle 30. The two sleeves 27 each carry a bevel wheel '28. These two bevel wheels mesh with a planet wheel; 29, the pivot of which is attached to the axle 30. The latter carriestwo ratchet wheels 31, 32, and a. worm wheel 33 revoluble freely on the axle 30, the latter wheel being so connected with the wheel 32 by a click or pawl 34 that The latter of the paper carriage, but is journaled im- I movable 1n the longitudinal direction and has at its ends a khob 36 with whichit can;

be rotated by hand. The spindle 35 acts in known manner during the operations of typewriting and as av rack when it is shifted by the wheel 33, but canbeused for exactly adjusting the paper carriage-to one definite point by its being rotated by meansof the knob 36. In this event the spindle- 35ractsas a screw and the stationary toothediwheel 33 in known manner as a nut. On. the

' ratchet wheels 2 1, 22, 23, 24 there act double" pawl's 40, 41, 42, 43.which are 'revoluble' aroundaxles144. With each of these pawls thereis connected a lever-arm'45'with which draw rods 46 engage, -The latter, again, I

lead to four universal bars 47 which 'are journaled below 'the keylevers. When a key 5fis depressed, the appertaining keylever 2 acts on one or more ofthe universal bars47 and shiftsthe paper carriage different distances in known manner. With the typewriter there is connected, further, a

unchmgdevice. The movement of the :ey's is transmitted' to the. punching-device with the aidof an electric'current. For this purpose there is attached to each key lever ahook 50 which engages under the extension 51 of a lever 52 made of electrically insulating'material. The lever 52 is attached on a.

spring 53 and is connected through this with a terminal 54. Below the lever 52 and the left-hand end of the spring 53 there is arranged a'contact screw 55 which is movable in a terminal 56. The terminals 54 and 56 are'attached on the ebonite plate 57. When a key is depressed the hook 5O releases the lever 52 and the spring 53 contacts with the screw 55. All the terminals 54 and 56 are connected in suitable manner with the electromagnets 58 of the punching device. Opposite each of theelectromagnets 58 there is an armature59 which is mounted on a bell-crank lever 60. The horizontal arms of the bell-crank levers 60 carry draw bars 61,

\ means of the rod 61, causes the corresponding hook 62 to withdraw the catch 65 oppo- -site to it from one of the levers 66. Consequently this lever rotates around the axle 68 and causes itsarm 69 to drive the punch 70 into the paper. At the same time the bar 71 is thrown back by the lever 66, so that with the aid of a known couplin device, the axle 72 comes into operation an brings the lever 66 into the normal position together with the eccentric 73 mounted on it which engages the arm 74 of the lever 66. The manner in which the punching device operates is known. Likewise the manner in which the .correct electromagnet and punch is selected with the aid of one single contact caused by a key is known."

Now the means which substantially form the subject-matter of the present invention are arranged on the combined typewriter and perforating machine represented in the accompanying drawings and briefly described above.

The means for canceling or eliminating one single perforated symbol consists of one simple key-lever corresponding to the keylever 2, which however is notconnected with or knob 36. The second device which is used for canceling entire words is operated by means of a lever 80, as clearly shown in Figs. 1 and 2. around the axle 81 and is connected with a lever 82 which has at its upper end a slot 83. In the latter there moves the pin 84: which is mounted on a draw rod 85. This rod is in the space between the body 1 of the typewriter and the frame 16 of the paper carriage. The rod has at one end a dog or pawl 86 which is attached revgluble to the draw rod 85. The dog has an arm 87 against which a spring 88 presses. In its normal position the rod 85 is pulled to the left by a spring 89 which is attached on the one hand to the pin 90 on frame 1 and on the other hand to the rod 85 at 91. Thus the arm 87 of the dog 86 hits against a pin 92 attached to the body of the typewriter and brings the dog into its lowest position. If

-the paper carriage is to be drawn backward when a written word is being removed, the composer grasps the lever 80 and presses it slowly downward. The rod 85 is then pulled to the right and the dog 86 being under the action of the spring 88 is placed in the teeth of a rack 94 mounted on the frame of the paper carriage. 'hen the rod 85 is moved still farther the. paper carriage is driven to the right. The worm wheel 33 then rotates backward, thepawl 34.- sliding ovcr the teeth of the wheel 32. In order to make the perforated symbol, which is used for removing the corresponding group of holes, at the same time as the paper carriage is drawn backward, when the lever 80 is operated a contact is closed. For this purpose the lever 82 has a nose or extension 95, which the hook of a draw rod 96 engages. The latter rod leads into the lower part of the frame of the typewriterand is attached there to a lever 97 98 which rotates around the axle 99. The arm 98 engages under an extension 51 of the contact lever 52. \Vhcn the rod 96 is raised on account of the lever 80 being depressed. the lever arm 98 releases the contact lever 52, corresponding to it and closes an electric contact which operates the punching device in the same manner as the contacts made by the type-levers. so that a symbol is punched in the hand. which symbol serves for removing the previously composed word.

The means for perforatingthe symbol for canceling entire lines are connected with the means for perforating the symbol for the end of the line. The band is perforated when the paper carriage is placed back to the beginning of the line and when a special key, the key for justifying a line, is depressed during the return movement of the carriage. For this purpose there is arranged on the paper carriage a rod 100, clearly shown in Figs. 1 and 3, which, after This lever is revoluble a screw 101 has beenloosened, can be shifted in the longitudinal direction of the paper carriage, in order to adjust the length of line. Onthe rod 100 two trippets or lifters 102 and 103 are attached by..means of P1118.

On the trippet 102 there is revolubly mounted a pawl 10 1. An extension 105 of this pawl lies on a shoulder 106 of the trippet 103. \Vhen the typewriter is operated the pawl slides from the=right t0v the left over two ratchet wheels 107 and 108, but

without rotating these wheels. When. the paper'carriage is pulled backward, the pawl 104- first drives the ratchet wheel 107 and then the ratchetwlieel 108 and rotatesea'ch wheel one tooth. A pawl 109 which is pressed by a spring 110 against the wheel 108 passes from below into the gaps between tact screw 112. Inthis manner an electrical connection is made between the terminals 113 and 114, and this contact causes the symbol for the end of the line to be perforated. A similar device is situated atthe wheel 107. .Here a .pawl 115 which is under the influence of the sprin 116 is provided with a leafspring 117 w ich contacts the contact screw 118 when the wheel 107 is rotated one tooth. The electrical connection which is made between the terminals 119 and 120 causes, in certain cases, the line-cancellation symbol to be perforated. The wheels 107 and 108 are rotated when the paper carriage is moved backward. In this case the symbol for the end of a line is always perforated owing to the wheel 108 rotatin The perforation of the symbol for canoe ing the line depends,

however, besides on the rotation of the wheel 107, on the line-cancellation key being depressed in addition. This key, like that for canceling one single symbol, is provided with a contact device. The contacts at the key for canceling lines and at the pawl 115 are connected in series, so that the symbol for canceling lines can only be perforated when both places at which the circuit is interrupted are closed simultaneously. This occurs when the key for canceling a line is ke t depressed while the paper carriage is being moved back into its commencing position. The symbol for canceling a line is perforated before the symbol for the end of a line, corresponding to the positions of the wheels 107 and 108.

The electrical connections between the contacts of the keys and the electromagnetcoils of the perforating device are represented diagrannnatically in Fig. 4. It is here presupposed that, in the case of the described perforating device, each character and each operation which isfto be done by the typesetting machine by means of the register band is represented by a perforated symbol which consists of two holes. Accordingly each key must release two punches in the perforating device. The number of punches must be so great that the different positions of the perforations suffice for characterizing in a distinguishable manner all'the characters, signs, and the like which occur. For eXample,'if thirty-six different signs and the like are provided, at leastnine punches must be employed in order. to be able to make thirty-six different pairs of holes. In the case of a larger number of characters and the like, the number of punches must be correspondingly increased. With the exception of the first and last, the electromagnets which release the punches have each two coils of which the one is connected with the positive pole and the other with the negative pole of a source of current. In Fig. 4, 125 denotes the source of current; 120 and 127 are the two groupsv of electromagnetcoils which are connected with the two poles of' the source of current. The individual coils are differentiated within these groups by letters a, to 71. and 12 to '5 respectively. The coil a, in the group 126 corresponds to the coil of the. first electrocorrespondsto the coil of the last electromagnet. Of the remaining coils, those, which are denominated-with like letters belong to the same electromagnet. From the coils a, to h, conductors a, to h, lead to groups of contact levers 128 which come spond to the contact levers 52 in Fig. 1. From the electromagnet coils. into '11, conductors b, to i, likewise lead to groups of contact screws 129 which correspond to the contact screws 55 in Fig. 1. The connection in groups of the contact screws 129 with the conductors b; to z, is such that a lever 128 which is connected with any one of the elecmagnet, whereas the coil 2' in the group 127 tromagnet coils a, to it, has opposite to it a contact screw which is connected with one of the electromagnets 11 to '5 this electro inagnet being always of higher place in the series than the electromagnet connected with the lever 128. In this manner with the aid of one single contact, two electromagnets can be simultaneously energized, which will also be readily understood from the diagram of connections. The manner in which and corresponds to a contact screw in Fig. 1. From the terminal 120 the conductor then leads to the coil of the second electromagnetwhich is 'to come into operation in the case of the concerned symbol. In Fig. 4 it is supposed that the electromagnet coils a and b, belong to the symbol for canceling a line and that consequently the first of the contact screws 129 isto be connected with the terminal 119 and the terminal 120 with the conductor 6,. From the representation shown in Fig. 4 it will be readily understood that when canceling aline two contacts are to be closed simultaneously, namely on the one hand the contact between a lever 128 and a screw 129, and further, the contact between the pawl 115 and the screw 118, when the current which occasions the perforation of the symbol for canceling a line is to be able to flow. derstood that the symbols for the individual cancellations or eliminations may be selected quite optionallv.

The mechanical devices for executing the principle of the invention Which' are here described may be modified in'many ways. For example, for canceling individual symbols a second device can be provided in the same manner as has been above described for canceling words. Also, for canceling lines the same device may be employed, it being taken for granted that the movement of the lever 82 can be made so great that the paper carriage is returned into the zero osition. Likewise, for the canceling sym ols, keys could also be arranged by means of which a source of power is brought into play which returns' the paper carria e.

When eliminating words an individual symbols the composer must take care that the paper carriage is returned exactly into the correct position. For this purpose a pointer must be arranged on the typewriter which indicates exactly the position at. which the type makes an impression. Such a pointer is clearly represented in Figs. 1 and On the body of the frame of the machine below the paper carriage there is. arranged in a pedestal 130 a pointer 132 revoluble around the pin 131. The pointer which is represented more particularly in Fig. 5 projects through the paper carriage and is so shaped that when the platen roll 8 is turned up the pointer lies at 133 at the place where the types strike. The pointer is enlarged at its lower end in order to securely journal the same, and has at the place where it lies against the paper a beveled edge 134 which denotes exactly the place where the types print. When setting the paper carriage after removing a word or character, the carriage must be so adjusted that the last remaining character just contacts the edge 134 from the left. The pointeris revoluble in the pedestal 130,-so that it can be moved It is to be unaway when the pa or carriage is turned up. When returning tic platen roll 8 into the normal position an extension 136 which is attached to the pointer 132 lies a ainst a.- stop 137 and prevents the pointer sliding on the paper during writing. In order to be able to exactly adjust the paper carriage after a word has been canceled, with the key for the space between two words there may be connected a type-lever which at each space between two words strikes a fine straight line or a similar mark on the paper, this line being so laced that it can serve as an adjusting mar after the removal of a word.
