Um mit den bisher gebräuchlichen Pappenscheeren schmalere Streifen schneiden zu können, als die Dicke des Messerbalkens mit dem Messer beträgt, wurde mit dem Anschlag für die Pappe ein sogen. Schmalschneider gelenkig verbunden. Diese bisherige Einrichtung ist auf beiliegender Zeichnung in den Fig. 1 bis 3 dargestellt, wobei die Fig. 1 und 2 die Vorrichtung in der Seitenansicht während zweier Arbeitsperioden zeigen und Fig. 3 eine obere Ansicht ist. Beim Niederdrücken des Messerbalkens M klappte dieser dann den Schmalschneider χ nach unten, so dafs das Messer M den Pappstreifen von der gewünschten Breite abschneiden konnte.In order to be able to cut narrower strips than the thickness of the cutter bar with the knife with the previously used cardboard scissors, the stop for the cardboard was a so-called. Narrow cutter articulated. This previous device is shown in the accompanying drawing in FIGS. 1 to 3, FIGS. 1 and 2 showing the device in side view during two working periods and FIG. 3 being a top view. When the knife bar M was pressed down, it folded the narrow cutter χ down so that the knife M could cut the cardboard strip of the desired width.

Diese Einrichtung arbeitet aber nur für gewisse, von der Breite des Schmalschneiders abhängige Streifen; sollte der Pappenstreifen die in Fig 1 durch die Stellung des Schmalschneiders χ angegebene Breite erhalten, so schnitt zwar das Messer, wie vorhergehend angeführt, diesen Streifen regelrecht ab, doch konnte der Messerbalken alsdann nicht ohne Gefahr für die Maschine wieder gehoben werden. Da der Schmalschneider χ von einer Feder (Fig. 3) bethätigt werden mufste, um für den folgenden Schnitt seine Anfangsstellung wieder einnehmen zu können, so klemmte er den hochgehenden Messerbalken fest, wie dies Fig. 2 deutlich zeigt. Wurde nun der Messerbalken mit Gewalt hochgehoben, so mufste ein Theil der Maschine brechen oder verbogen werden. Im ersteren Falle war die Maschine zur weiteren Arbeit untauglich und im letzteren Falle erhielten die ferner geschnittenen Pappenstreifen nicht mehr die vorgeschriebene Breite.However, this device only works for certain strips that are dependent on the width of the narrow cutter; If the cardboard strip should get the width indicated in Fig. 1 by the position of the narrow cutter χ , the knife actually cut this strip off, as previously mentioned, but the cutter bar could then not be lifted again without danger to the machine. Because of the narrow Schneider χ by a spring (Fig. 3) bethätigt was obliged to take up again for the next section to its initial position, he stalled the high-going cutter bar, as clearly shown in FIG. 2. If the cutter bar was now lifted by force, part of the machine would have to break or be bent. In the former case the machine was unsuitable for further work and in the latter case the further cut cardboard strips were no longer given the prescribed width.

Diese Uebelstände zu beseitigen und eine Einrichtung zu schaffen, mit deren Hülfe genau gleiche Streifen geschnitten werden können, ist Zweck der vorliegenden Erfindung, nach welcher der beliebig einzustellende Anschlag beim Niederdrücken des Prefsbalkens selbstthätig um so viel verschoben wird, dafs der Messerbalken nunmehr ungehindert bei dem Anschlag vorbeigehen kann, wobei letzterer aber sofort seine Anfangsstellung wieder einnimmt, sobald der Prefsbalken gehoben ist.To remedy these evils, and to create an arrangement with the help of which precisely equal strips can be cut, is the purpose of the present invention, according to which the stop, which can be set as required, automatically reverses when the pref beam is pressed down is shifted so much that the cutter bar can now pass the stop unhindered can, but the latter immediately resumes its initial position as soon as the Prefsbalken is raised.

In den Fig. 4 bis 8 ist diese neue Einrichtung in ihren Einzelheiten und in ihrer Zusammenstellung gezeigt, während Fig. 9 schaübildlich eine mit der Neuerung ausgestattete Pappenscheere zeigt.In FIGS. 4 to 8 this new device is in its details and in its composition shown, while Fig. 9 schematically equipped with the innovation Cardboard scissors shows.

Auf die Welle a, Fig. 7, 8 und 9, durch deren Drehung mit Hülfe der Kurbel b, Fig. 9, und unter Vermittelung der auf ersterer festen Zahnräder c cl die den Anschlag A tragenden Zahnstangen ddl bewegt werden, ist die Hülse B lose aufgeschoben. Diese Hülse B besitzt an ihrem vorderen Theil Gewinde und kann mit Hülfe der Schraube e fest mit der Welle a verbunden werden. Ueber den Gewindetheil der Hülse B ist der Hebel C, Fig. 5 und 8, geschoben, dessen Ende durch die Schubstange D mit dem Tritthebel f für den Prefsbalken E gelenkig verbunden ist (Fig. 9). Das Auge des Hebels C für den Durchgang der Hülse B ist konisch ausgebohrt und auf das Gewinde dieser Hülse die Mutter F geschraubt, deren dem Hebel C zugekehrter Theil ebenfalls konisch abgedreht ist. Beim Anziehen der Mutter F legt sich der konische Theil derselben fest in die Bohrung des Hebels C, und da derselbe hierbei gleichzeitig fest gegenOn the shaft a, Fig. 7, 8 and 9, through the rotation of which with the aid of the crank b, Fig. 9, and with the mediation of the fixed gear wheels cc l on the former, the racks dd l supporting the stop A are moved, is the sleeve B pushed on loosely. This sleeve B has a thread on its front part and can be firmly connected to the shaft a with the aid of the screw e . The lever C, FIGS. 5 and 8, is pushed over the threaded part of the sleeve B , the end of which is connected in an articulated manner by the push rod D to the step lever f for the Prefsbalken E (FIG. 9). The eye of the lever C for the passage of the sleeve B is bored conically and the nut F is screwed onto the thread of this sleeve, the part of which facing the lever C is also turned off conically. When the nut F is tightened, the conical part of the same lies firmly in the bore of the lever C, and at the same time firmly against it

den vorspringenden Bund (Fig. 4) der Hülse B geprefst wird, so werden durch kräftiges Anziehen der Mutter F Hebel C und Welle a fest mit einander verbunden. Beim Niederdrücken des Tritthebelsy wird also nicht allein der Prefsbalken niedergezogen, sondern auch Welle α mit Hülfe der Schubstange D und des Hebels C gedreht, so dafs gleichzeitig der Anschlag A von dem Tisch entfernt wird. Der Messerbalken Mkann, ohne von dem Anschlagt behindert zu sein, abwiirts bewegt, aber auch mit ,derselben Leichtigkeit wieder hochgehoben werden, da ein Klemmen desselben an dem abgerückten Anschlag nicht möglich ist.the protruding collar (Fig. 4) of the sleeve B is pressed, then by vigorously tightening the nut F lever C and shaft a are firmly connected to each other. When the step lever y is pressed down, not only the prefsbalken is pulled down, but also the shaft α is rotated with the aid of the push rod D and the lever C , so that at the same time the stop A is removed from the table. The cutter bar M can be moved downwards without being hindered by the stop, but can also be lifted up again with the same ease, since it is not possible to clamp it on the withdrawn stop.

Werden so breite Streifen geschnitten, dafs infolge der weiten Entfernung des Anschlages ein Einklemmen des Messerbalkens überhaupt unmöglich ist, so kann die neue Vorrichtung dadurch ganz aufser Thätigkeit gesetzt werden, dafs man die Mutter F auf der Hülse B so weit löst, dafs die durch Pressung veranlafste Verbindung des Hebels C mit der Hülse B aufhört. Der Hebel C schwingt demnach beim Auf- und Niedergang des Tritthebels f lose auf der Hülse B hin und her, während der Prefsbalken dagegen, wie gebräuchlich, niedergezogen wird. Da der lose schwingende Hebel C die Hülse B und mit dieser die Triebwelle α für die Stellstangen d dl des An Schlages A nicht bewegen kann, so bleibt letzterer naturgemäfs an der ihm angewiesenen Stelle stehen, und die Maschine arbeitet in der bekannten Weise.If strips are cut so wide that, because of the great distance of the stop, it is impossible to pinch the knife bar, the new device can be put on its own by loosening the nut F on the sleeve B so far that it is pressed by pressing initiated connection of the lever C with the sleeve B ceases. The lever C therefore swings loosely back and forth on the sleeve B when the step lever f rises and falls, while the prefsbalken, on the other hand, is pulled down as is customary. Since the loosely swinging lever C cannot move the sleeve B and with it the drive shaft α for the control rods dd l of the stop A , the latter naturally remains at the point assigned to it, and the machine works in the known manner.

Bei der Abänderung nach Fig. 10 ist der Hebel C als Gelenk ausgebildet, welches mittelst einer Flügelmutter auf der Welle α festgeklemmt werden kann. Auch hier hat man nur nothig, die Flügelmutter zu lösen, um den Apparat aufser Thätigkeit zu setzen.In the modification according to FIG. 10, the lever C is designed as a joint which can be clamped onto the shaft α by means of a wing nut. Here, too, it is only necessary to loosen the wing nut in order to put the apparatus into operation.
