Application filed. September 23, 1913. Serial No. 791,270.

To all whom it may concern Be it known that I, HEINRIGH DREWELL, a subject of the German Emperor, residing at Charlottenburg, Germany, have invented new and useful Improvements in Band- Perforating Apparatus, of which the following is a specification.

My invention relates to apparatus for making perforated bands for operating automatic typesetting machines, automatic matrix-setting and line-casting machines and the like. 5

A primary object of my invention is to exactly with the text written by the typewriter connected with the perforatingde vice. Such agreement is of considerable im- 7 portance because without it the text would not fulfil its purpose, e. that of serving as an aid in making corrections. The agreement is, however, rendered difficult owing to certain occurrences which are unavoidable in the case of rapid working, 6. g. the simultaneous partial depression ofseveral keys, and the like. In order to render such mistakes non-injurious I make the selection of the punches used for. perforating the band dependent on that type-bar of the typewriter which carries the type corresponding to the perforated symbol, by causing the type-bar to select the punch only when in proximity to its printing position. In addition, a very elastic and light stroke of the key is obtained in this manner. The certainty of operation is based, on the one hand, on all the type-bars having to be brought into an exactly predetermined end position in order to bring about both the printing of the types and also the selection and action of the punches andfon the other hand, on a type-bar which does not arrive into this end position causingneither the one nor the other function tobe'performed. Consequently, a keypcan be depressed through three-quarters of its stroke, for example, without its bccomingoperative, whereas both printing and perforation take place with out'fail when the key is struck in the ordinary manner withsuflicient force. The certainty of action is increased owing to the type-bar acquiring a certain velocity when it is struck in the ordinary manner, and owing to" its being able by means'of the impetus thereby acquired tobring about both the printing of thetype and alsothe production of the perforated symbol even should the ters of a particularly finger which strikes the key leave the latter too soon, Thus the proper action of the blow on the key depends not only on the extent of the movement which the finger directly imparts to the key, but also on the energy of this movement. Consequently, keys which are depressed owing to their being unintentionally struck when an adjacent key is struck produce neither a print nor a perforated symbol, because inby far the majority of cases such keys are struck only lightly and the key or the type-bar does not move at any high speed" On the other hand, the two type-bars which operate simultaneously must necessarily strike together at the same point,so that defective operation is recognized without fail in this manner by the operator and can be rendered non-injurious.

The invention can be employed in combination with typewriters and perforating devices of very various construction. Both typewriters without shift-keys and also those comprising the same may be used. In the following description it is assumed that a typewriter comprising a shift-key is used, and a mode of changing over to capital letadvantageous kind in such cases is described.

To these ends the invention consists inthe construction, arrangement and combination tion of the Underwood system and comon the key-levers 1, entering into slots in thelevers 2. Driving pins 8 on the levers 2 enter into slots 9 in the type-bars 3 and impart tothese the motion of the key-levers. The typebars rotate about the curved ward a small distance.

The mode of operation of the typewritingmechanism is the same as that of the wellknown Underwood typewriting mach1ne.

In order to produc'e'a perforatlon 1n the 'ing of the types the motion of the'type-bars is imparted to a device for selecting punches. For this purpose, the type-bar 3 has a shoulder 18 near its fulcrum. Vhen a .key.12 1s ,,depress'ed and the type-bar 3 is consequently Wends' of which slide'in guides 20 and i "Each of the rods 19 is coniiected with numberof. levers, in the present .case two,

The lower ends of the levers 23 and 2 1 are guided lat erallyin a comb-like guide 28, and a similar guide 29 guides the bands 25 laterally.

I-These bands are themselves under the 1n-; ,fiu ence of springs tending to pull them rearwardly, the springs being fastened 1n suitable: manner to a cross-bar 51. The" bands 25 are provided with teeth or lugs 53,

with which theycoact with cross-bars 54 and thereby bring about the selection ofthe "punchesin the'manner described hereinafter. 7 r Each of the rods 19 acts on two or more levers 23'and 24, the number thereof depending'on the number of types provided at the end of each'type-lever.

small gap through which the band 60 to be perforated is drawn. The grooves of the guide 57 in which the punches 56 slide are covered over bycovers6l and 62. Between the two covers is a gap in which lugs 63 of the punches move. These lugs are for returning the punches after use into their normal position. Each punch is provided at one end with a round, spherical or cylindrical head 64 engaged byan angle lever 65, 66. The arm 66.0f this lever isunder the influence of a spring 67 which tends to rock it so that the arm 65 is located in the path of a bar 68. This is prevented in y the normal position of the apparatus by a projection 69 on a bar 1. These bars 54 are mounted with two knife-edge like pivot pins or fulcrums 72 in recesses in bearings 73 and are rotatable about the lower edges of the fulcrums 72. The covers 74 prevent "the fulcrums 72 being lifted out of the bearings 73. The bars 54 are under the influence of springs 76 having one end attached to lugs 78 on the bars. The other ends of these springs are attached to a cross-bar 79 attached in suitable manner to the frame of the machine.

The apparatus as described above operates as follows :VVhen a key 12 is depressed and the type-bar 3 is thrown against the platen,

the lug 18 drives the corresponding rod 19 rearwardly, the two levers 23 and 24 connected with the rod being driven. One of these levers rocks about its lower end, 2'. 6.,

Z-about the point of support against the bar 28, while the other lever rocks about the edge 30 of the change-over shaft 32 or, in event of the shift-key having been operated, the other lever rocks about the edge 31 of the same shaft. That lever which looks about the lower point of support of the bar 28 exercises no action on the selection of punches or on other parts of the apparatus. The other lever rocklng about one .of the edges of the shaft 32 causes one of the combination bands 25 to be pulled forward. The teeth 53 of this band act on cross-bars 54 which are thereby rocked about the lower edges of the fulcrum 72. Each projection 69 of the cross-bars in question is shifted so much that it releasesthe arms 66 of the angle levers 65, 66 in operative relation therewith. These angle levers are rocked so far that the free ends of the arms arrive in front of the bar 68. This bar forms a part of a striking frame which whenever a key is struck is moved forward and backward by means of cams, whereby the selected levers 65, 66 together with the punches 56 pivotally connected to them are driven forward and perforate the paper band 60. The mechanism for driving the cams is described in detail in my American Patents No. 98898 1 dated the 11th day of April, 1911 and No. 1001825 dated the 29th day of August, 1911 and therefore need not be described here.

In the above described arrangement for selecting the punches the rod 19 which brings about the selection can be driven by the momentum of the type-bar associated therewith when the key in question receives a short, but suficiently powerful blow. This is of material importance for the production of a correct perforated symbol which corresponds to the struck key. In perforating devices known heretofore which were connected with a typewriter, the unintentional partial depression of a key could produce an incorrect perforated symbol because there was so much lost motion between the key and the type-bar, on the one hand, and the key and the member for selecting the punch, on the other hand, that the typebar and the member for selecting the punch could operate independently one of the other when a key was depressed only a little. This is impossible in my arrangement because the member for selecting the punch cannot be driven otherwise than by the type-bar and is driven thereby only during the last part of its movement. In consequence of the latter circumstance, when a key is insutficiently depressed and the type-bar is not moved suflicient-ly neither a perforated symbol is produced nor is a type printed. On the other hand, it is not necessary to depress each key specially carefully into its lowest position because the swing or impetus of the rapidly moved type-bar sutlices for both printing the type and also for driving the punch-selecting member 19. Accordingly, it is not so much the extent of the movement of the key as the energy of the stroke which is important for the correct action of the latter. In this way, one of the most important conditions for rapid, but nevertheless certain and correct working of the machine is fulfilled.
