KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der dargestellte Bleistifthalter wird aus einem Blechstück ABCDE, Fig. 1, zusammengebogen, das den Spalt ARP und eine gegen A D zurücktretende Kante PB hat. Der vordere , zwischen PB liegende Theil verhindert also, dafs die Längskanten des Bleches gegen einander stofsen, Fig. 2, und würde durch die Elasticität des Theiles PBR C allein schon das Blei festgeklemmt werden. Diese Elasticität wird aber durch den über PBR C geschobenen Rjng inn, Fig. 3, noch erhöht. Letzterer ist· mit schrägen Kanten zusammengerollt, so dafs am Zusammenstofs eine Spirale entsteht. An dem vorderen Theil des Halters sind die Federn ST befestigt und auch, mn trägt eine derartige Feder s. Wird der Ring mn über, die Federn S T geschoben, so wird das Blei durch die eigene Elasticität des Ringes wie durch die der Federn S T und ί fest eingeklemmt. The pencil holder shown is bent from a piece of sheet metal ABCDE, Fig. 1, which has the gap ARP and an edge PB receding towards AD . The front part lying between PB prevents the longitudinal edges of the sheet from hitting one another, Fig. 2, and the lead would be clamped by the elasticity of the part PBR C alone. This elasticity but inn by the pushed-on PBR Rjng C, Fig. 3, even increased. The latter is rolled up with sloping edges so that a spiral is created at the joint. The springs ST are fastened to the front part of the holder, and also, mn carries such a spring s. If the ring mn is pushed over the springs ST , the lead is replaced by the own elasticity of the ring as by that of the springs ST and ί firmly clamped.
