Kopfschraube. Patentiert int Deutschen Reiche vom 10. Januar 1924 ab.Cap screw. Patented by the German Empire on January 10, 1924.

Die bekannten Kopf schrauben (Abb. i)sindThe familiar head screws (Fig. I) are

meistens aus einem Stab oder Draht von dem Durchmesser des Kopfes α durch Abdrehen herausgearbeitet. Diese Herstellungsart ist mit verhältnismäßig beträchtlichem Materialverbrauch verbunden und erfordert an Arbeitszeit unter allen Umständen die Zeitdauer des Abdrehens des Schraubenschaftes b. Soll beispielsweise der Durchmesser des Kopfes a doppelt so groß sein als der Druchmesser desmostly machined from a rod or wire with the diameter of the head α by turning. This type of production is associated with a relatively considerable consumption of material and requires the time required to turn the screw shank b in terms of working time under all circumstances. If, for example, the diameter of the head a should be twice as large as the diameter of the

Schaftes b, so werden fast drei Viertel des gesamten Materials von dem Schaft b heruntergedreht und zu Spänen verarbeitet.Shank b, almost three quarters of the entire material is turned down from the shank b and processed into chips.

Bei der neuen. Kopfschraube kann, wie es in einem Ausführungsbeispiel in Abb. 2 in Seitenansicht und teilweisem Längsschnitt dargestellt ist, der Schaft c der Schraube unmittelbar aus einem Stab oder Draht von der für (den Schaft gewünschten Stärke ohne irgendwelches Abdrehen hergestellt werden. In den Schaft c wird lediglich eine Nut d eingedreht, in welche ein federnder Ring e eingelegt wird. Die Unterlagscheibe / wird entweder vor dem Einlegen des Ringes über das Kopfende des Schaftes oder von dem anderen Ende der Schraube her über den Schraxibeiischaft geschoben und weist eine Ausnehmung (Einsenkung) g auf, deren Durchmesser gleich dem Außendurchmesser desWith the new one. Head screw, as it is shown in one embodiment in Fig. 2 in side view and partial longitudinal section, the shank c of the screw directly from a rod or wire of the shank desired for (starch without any one twisting be prepared. C is in the shaft just screwed a groove d into which a resilient ring e is inserted. The washer / is either pushed over the head end of the shaft or from the other end of the screw over the screw shaft before the ring is inserted and has a recess (indentation) g whose diameter is equal to the outside diameter of the

ao Ringes e ist. Dadurch haftet die Unterlagscheibe /, wenn sie über den Ring e geschoben wird, an diesem, und es ist bei oder nach dem Anziehen der Schraube selbst durch starken Druck nicht möglich, die Unterlag-ao ring e is. As a result, the washer /, when pushed over the ring e, adheres to it, and it is not possible, with or after the screw is tightened, even by applying strong pressure to the washer.

Die Ausnehmung (Einsenkung) g kann, statt in einer besonderen Scheibe /, auch unmittelbar in dem mittels der Schraube festzupressenden Teil sich befinden. Der federnde Ring e kann aus einem schraubenförmig gewickelten Draht hergestellt sein, der zur Gewinnung von. Ringen e der Länge nach aufgeschnitten wird. Zum Anziehen der Schraube kann deren Kopfende h ini irgendeiner an sich bekannten Art ausgebildet, beispielsweise mit einem Schlitz/ oder mit einem Vierkant o. dgl. versehen sein.s5 washer / or the ring e to be pressed over the screw. The recess (depression) g , instead of in a special disk /, can also be located directly in the part to be pressed tight by means of the screw. The resilient ring e can be made of a helically wound wire that is used to obtain. Rings e is cut lengthways.
