Bei den bekannten Stanzmaschinen, bei welchen mittels eines Griffes ein die Typen trogen- ' des Rad gedreht wird, um die in das Material. einzudrückende Type in die Druckstellung zu bringen, und mittels eines zweiten Griffes der die Type niederdrückende Stempel bewegt wird, ist keine Vorkehrung getroffen, das Material bei jeweiligem Druck nur um ein so grofses Stück vorwärts zu bewegen, als der Breite der entsprechenden Type entspricht.In the known punching machines, in which by means of a handle a type of trogen- ' The wheel is rotated to get into the material. type to be pressed into the print position bring, and by means of a second handle moves the stamp that depresses the type is, no precaution is taken, the material at the respective pressure just so to move a large piece forward than the width of the corresponding type.

Bei der vorliegenden Zuführungsvorrichtung des Materials wird dies durch einen Daumen 48 mit abgeschrägter Anlauffläche bewirkt, welcher der Breite der zu stanzenden oder druckenden Type entsprechend früher oder später unter die Klinke des die Zuführungswalzen bewegenden Schaltwerkes geschoben wird und somit die Schallung früher oder später unterbricht. Der genannte Schieber steht unter der Kinwirkung eines Hebelgestänges, welches durch angesetzte, in Zahl und Höhe der Zahl und Breite der Typen oder Buchstaben entsprechende Anschläge in Schwingung versetzt wird, die am Rande des Typenrades oder eines mit diesem verbundenen Matrizenrades angebracht sind. Der Schieber kann als drehbarer Ann ausgebildet sein, der lose auf der Welle des Schaltwerkes sitzt.In the present feeder of the material, this is done by a thumb 48 with a beveled run-on surface, which is the width of the one to be punched or printed Type accordingly sooner or later under the pawl of the one moving the feed rollers Switching mechanism is pushed and thus interrupts the sounding sooner or later. The said slide is under the action of a lever linkage, which through attached, corresponding in number and height to the number and width of the types or letters Stops is set in vibration, which is on the edge of the type wheel or one with this connected die wheel are attached. The slide can be used as a rotatable Ann be designed, which sits loosely on the shaft of the rear derailleur.

Bei der dargestellten Ausführungsform einer Stanzmaschine ist das Typenrad j mit dem Matrizenrad A^- fest verbunden und sitzt auf dem dünneren Theile /; einer lothrechten HoIiI-achsc g (Fig. 1, 2 und 3). Das vereinigte Typen- und Matrizenrad j k steht mit dem Triebe / in fester Verbindung, welches durch das Zahnradsegment y in Drehung versetzt wird. Letzteres besteht mit dem an der Stütze ^ drehbar angebrachten und mit dem Griff 4 ausgestatteten Arm 1 aus einem Stück. Zum Niederdrücken der vom Rade j getragenen Typen ist ein Stempel oder Hammer 10 vorgesehen, welcher an einem am Bock 17 dreh-, bar gelagerten Hebel 1 1 befestigt ist (Fig. 3). Der Bock 17 ist zu diesem Zwecke mit seinem oberen Ende 18 gabelförmig ausgebildet. Das innere Ende des Hebels 11 ist durch die Stange 12 mit dem einen Griff 16 tragenden und bei 14 drehbar am Maschinengestell gelagerten Arm 13 verbunden. Der Arm 13 ruht auf einer Schraubenfeder 15, welche ihn nach erfolgtem Niederdrücken mittels des Griffes 16 wieder anhebt. Das andere Ende des Hebels 11 ist durch die einstellbare Stange 22 mit einem Arm 21 (Fig. 2) des am Ansatz 19 des Bockes 17 drehbar gelagerten Winkelhebels 20 verbunden, dessen zweiter Arm 23 durch die Stange 24 mit einem auf der Welle 26 sitzenden Kurbelarm 25 in Verbindung steht. Die Welle 26 ist in den Lagern 27 des Maschinengestellcs"gelagert (Fig. 5). Am oberen Ende des Kurbelarmes 25 befindet sich eine federbelastete Klinke 28, welche zwischen die Zähne des Schaltrades 29 eingreift,, welches mit der auf der Welle 26 festsitzenden ,Walze 30 fest verbunden ist (Fig. 1, 4 und 5).In the illustrated embodiment of a punching machine, the type wheel j is firmly connected to the die ^{wheel A -} and sits on the thinner part /; a lothrechten hoiii achsc-g (Fig. 1, 2 and 3). The combined type and die wheel jk is firmly connected to the drive / which is set in rotation by the gear wheel segment y. The latter consists of one piece with the arm 1 rotatably attached to the support and equipped with the handle 4. To depress the types carried by the wheel j , a punch or hammer 10 is provided, which is attached to a lever 11 rotatably mounted on the bracket 17 (FIG. 3). For this purpose, the bracket 17 is fork-shaped with its upper end 18. The inner end of the lever 11 is connected by the rod 12 to the arm 13 which carries a handle 16 and is rotatably mounted at 14 on the machine frame. The arm 13 rests on a helical spring 15, which lifts it again by means of the handle 16 after it has been pressed down. The other end of the lever 11 is connected by the adjustable rod 22 to an arm 21 (FIG. 2) of the angle lever 20 rotatably mounted on the attachment 19 of the bracket 17, the second arm 23 of which through the rod 24 to a crank arm seated on the shaft 26 25 communicates. The shaft 26 is mounted in the bearings 27 of the machine frame "(Fig. 5). At the upper end of the crank arm 25 there is a spring-loaded pawl 28 which engages between the teeth of the ratchet wheel 29, which with the Roller 30 is firmly connected (Fig. 1, 4 and 5).

Claims

This roller 30 together with the upper roller 31 forms the feed device for the to be printed or punched strips, the latter unwound from the roll 32 or can also be fed in some other way, the strip being drawn in by the said rollers and is conveyed between the punch and die wheel. The spring 33 of the pawl 28 (Fig. 2) detects an approach of the latter above the pivot point, the pawl either is brought into engagement or out of engagement with the ratchet gear 29. At the handle sits an arm or handle 34, with the help of which this engagement or the disconnection by hand can be effected. The upper roller 31 is rotatably supported in the movable bearings 35. Between these bearings and the upper part of the machine frame are springs 36 switched on, which press the roller 31 against the roller 30. The role 31 is connected to a device with the aid of which it is lifted off the roller 30 can be used to introduce a new strip. This device consists of one Crank arm 37 which is rotatably attached to the machine frame and has a handle 38 is equipped, and also of a rod 39, which connects the arm to the bearing, whereby the roller 31 can be raised and lowered by the movement of the arm, in order to bring them into contact with or with the roller 30.

By moving the lever, 11 becomes the strip to be punched with the aid of the angle lever 20, the pawl 28, the ratchet wheel 29 and the rollers 30 and 31 are advanced intermittently. To this advance movement accordingly To regulate the different widths of the characters to be punched, comes the following device in use.

A rotatable thumb 48 is loosely seated on the shaft 26 and is carried along by the rod 49 one end of the lever 50 is connected or rotatably seated on the bracket 51 of the frame (Figures 2 and 4). The thumb 48 has a beveled contact surface, which when moving the thumb engages under the pawl and this engages with the ratchet lifts. The other end of the lever 50 engages the path of a number of projections 52 and 52 Recesses 53, which are attached to the underside of the die wheel A. the Letters and other characters are on the type wheel in different positions. - brought up, with the differences in the Location can be determined by the width of the characters. The letter is used as the normal letter M both in terms of width and in terms of position. The right edge of this letter serves as the starting point for the right edge of the other letters or characters. The wells 53 at on the underside of the die wheel stand loth- right over the wider letters, while the protrusions 52 are perpendicular to the narrower letter. Therefore becomes a wide letter, such as 2. B. M, is brought into print position, the inner end of the Lever 50 is raised while the outer arm is depressed together with the thumb 48 so that the pawl 28 engages the ratchet wheel and continues to rotate and the strip around the correct distance is conveyed. The feeding of the strip corresponds to the duration of the Contact between the pawl and the ratchet wheel 29. Should be a narrow letter, such as z. B. I, are used, a projection 52 engages the lever 50 so that the thumb is caused that the pawl is lifted off the ratchet when the pawl the has reached a predetermined position, so that the feeding of the strip is a relative one lesser becomes, etc. By means of a spring 54 the inner end of the lever 50 held in the path of the projections and depressions.
