  Einrichtung zur Befestigung von Ahlen in ihren Heften. 



   Den Gegenstand vorliegender Erfindung bildet eine Einrichtung zur sicheren Befestigung von Ahlen in ihren Heften, welche gleichzeitig bei   nnverdrehbarer   Festlegung derselben eine leichte Auswechselbarkeit der Stifte gestattet. Der Erfindungsgegenstand ist in Fig. 1 in Ansicht dargestellt. Fig. 2 zeigt eine schaubildliche Darstellung eines Klemmstücks. 



   In dem gebräuchlichen Hefte a aus Holz Ist ein   Einsatzstück   b aus Metall eingesetzt, welches eine schwach konische Bohrung aufweist ; zur Festlegung der Ahle b werden zwei oben mit   emem   Wulst versehene und der Bohrung des Einsatzstückes b entsprechende Klemmstücke c von halbkreisförmigem Querschnitt verwendet, die an ihre   Schnittseito   je eine der Stärke der verwendeten Ahle entsprechende Hohlkehle aufweisen. 



  Die Ahle wird in diese von beiden Hohlkehlen gebildete Rinne eingelegt und hierauf die 
 EMI1.1 
 infolge der Keilwirkung auftretende Reibung wird die   Ahle   sicher und leicht auswechselbar in dem Hefte gehalten.

  Device for attaching awls in their exercise books.



   The subject matter of the present invention is a device for securely attaching awls in their booklets, which at the same time allows the pins to be easily exchanged while they can be rotated. The subject of the invention is shown in Fig. 1 in view. Fig. 2 shows a diagrammatic representation of a clamping piece.



   In the usual booklet a made of wood, an insert piece b made of metal is used, which has a slightly conical bore; To fix the awl b, two clamping pieces c of semicircular cross-section, provided with a bead at the top and corresponding to the bore of the insert b, are used, each of which has a groove corresponding to the thickness of the awl used on their cut side.



  The awl is inserted into this groove formed by the two flutes and then the
 EMI1.1
 As a result of the friction occurring due to the wedge effect, the awl is held securely and easily exchangeable in the handle.
