Gegenstand vorliegender Erfindung ist ein Werkzeug zum Ausschneiden von Kerben an Baum- oder Aststümpfen für einzusetzende, gaisfußförmig zugeschnittene Edelreiser.
Das Werkzeug soll das große Übung erfordernde und teure Ausschneiden mit der Hand entbehrlich machen.The subject matter of the present invention is a tool for cutting out notches on tree stumps or branch stumps for gaisfoot-shaped trimmings to be used.
The tool is intended to make cutting out by hand, which requires great practice and expensive, unnecessary.

Es sind verschiedene, für Pfropfzwecke bestimmte Werkzeuge bekannt, z. B. das Pfropfmesser der Patentschrift 14969 für den sogenannten Zungenschnitt. Mit diesem den Wildling oben in zwei abstehende Teile spaltenden, für Baumveredelung überhaupt nicht dienlichen Werkzeug können jedoch Kerben für Gaisfußschnittveredelung nicht ausgeschnitten werden. Ebensowenig ist hierfür die Zuschneidvorrichtung für Pfropfzwecke der Patentschrift 124191 geeignet, denn die beiden keilförmig gegeneinander gestellten Messer dieser Vorrichtung schneiden quer unten wie oben gleich tief in den Wildling ein, wobei es noch eines weiteren, senkrecht von oben herab wirkenden und mittels besonderen Hebels zu bewegenden Messers bedarf, um den durch ersterwähnte Messer angeschnittenen Teil von dem Wildling zu trennen. Auch die Vorrichtung der amerikanischen Patentschrift 690865 für die sogenannte Kopulationsveredelung, schräge Verbindung desVarious tools intended for grafting purposes are known, e.g. B. the graft knife the patent specification 14969 for the so-called tongue cut. With this the wildling splitting into two protruding parts at the top, not at all useful for tree grafting However, notches for gaisfoot cut refinement cannot be cut out using tools. Neither is the cutting device for this purpose suitable for grafting purposes of the patent specification 124191, because the two Wedge-shaped against each other knife of this device cut across the bottom like at the top straight into the wildling, with another one, vertically from above down-acting and by means of a special lever to be moved knife requires to the to separate the cut part from the wildling by the first-mentioned knife. Even the device of the American patent 690865 for the so-called copulation refinement, oblique connection of the

Wildlings mit einem gleich starken Edelreise, ist für den Zweck des vorliegenden Werkzeugs nicht brauchbar.Wildlings with an equally strong noble trip, is for the purpose of the present Tool not usable.

Das vorliegende neue Werkzeug dient dagegen dem mechanischen Ausschneiden der Kerben an Wildlingen zum Einsetzen gaisfußförmig zugeschnittener Edelreiser in einem einzigen Schnitt.The present new tool, however, is used to mechanically cut out the Notches on wildlings for inserting gaisfoot-shaped trimmings in one single cut.

Claims

Angular cutting edge of the knife d corresponding approach e formed. With this approach, the tool after the knife d by lifting the handle /; is withdrawn, placed on the stump of the branch or tree to be grafted. The approach then ensures, in conjunction with the rearward-facing foot η of the guide frame bc, the oblique cutting effect of the

ίο knife d and is also used to measure the desired depth of the notch exactly. As soon as the handle h is turned downwards after the attachment e has been placed on the wildling, the knife d, which has been resting in front of the bark of the wildling until then, cuts the desired notch after the attachment e smoothly in a single cut so that the notch starts sharply at the bottom and widens evenly upwards, sideways and inside. The cut piece has the shape of a three-sided pyramid. The rails 2 and k are arranged laterally on the handle h. These are articulated with the tie rods / and m ; the knife d is hinged to the latter. The handle h is designed as a ζλνεί-armed lever, the pivot point of which lies in the bracket f connected to bc. To enable the knife d to be removed, the upper part of one guide strip b is arranged in a detachable manner by screwing.

As can be seen from the above, the new and peculiarity of the tool described consists of the open guide frame bc connected to the corresponding handle α with protruding rear approach e for placing on the wildling and the back and forth in the guide frame bc , with another handle h connected angled knife d, the oblique cutting effect of which is secured by the shoulder e in connection with the rearwardly directed foot η of the guide frame bc .

The tool can also be made in the form of pliers . Such an embodiment is shown in FIG. 15, which shows the tool with an open knife d set on a wildling. In this case, the guide frame has been fixed or detachable with one pincer handle α ¹ , the angled knife d with the other pincer handle Z? ¹ connected so that the trestle /, the rails i and k and the tie rods / and m are eliminated. ·.

Pate nt-A ν SPRU c η:

Tool for cutting out notches in tree or branch stumps for gaisefoot-shaped trimmings to be inserted, characterized by an open frame (bc) which is provided with a handle (α) and is used to guide a knife with an angled cutting edge and which has an attachment (e) on the one end is equipped as an abutment for the knife (d) and a stop (n) at the other end for making the oblique cut, for the purpose of making notches of the desired depth for gaisfoot-shaped trimmings.
