THIESEN & CO. in BERLIN. Doppelköpfige Kernnägel. THIESEN & CO. in Berlin. Double headed core nails.

Patentirt im Deutschen Reiche vom 24. December 1885 ab.Patented in the German Empire on December 24, 1885.

Die bekannten doppelköpfigen Kernnägel haben den Uebelstand, dafs sie für jede Wandstärke besonders vorhanden sein müssen und nach der Benutzung viel Zeit mit dem Sortiren verloren geht. In vorliegender Erfindung wird dieser Mangel dadurch beseitigt, dafs einer oder beide Köpfe auf dem Nagel verschiebbar und fesstellbar sind. In Fig. 1, 2 und 3 ist dieses derart angeordnet, dafs der eine Kopf K1, Fig. ι und 2, oder beide Köpfe K und K1, Fig. 3, zwischen Muttern m1 bezw. m gestellt und festgehalten werden, zu welchem Zwecke die Nägel N ganz oder theilweise mit Gewinde versehen sind. In Fig. 4 ist der Nagel N ebenfalls mit Gewinde versehen und ebenso die verschiebbare Platte K1 (bezw. auch K entsprechend Fig. 3 und K1 entsprechend Fig. 2), wodurch die Muttern m1 (bezw. m) in Fortfall kommen; aufserdem kann zur besseren Feststellung an K1 die aufgeschnittene Hülse h sein, welche solchergestalt federnd wirkt und nur einer bedeutenderen Kraft beim Verschieben weicht, auch das leichte Schrauben zwischen K bezw. K1 und N hindert. Hieraus ergiebt sich, dafs auch das Gewinde überhaupt fehlen kann. Noch eine andere Art der Feststellung des verschiebbaren Kopfes K bezw. .ST1 zeigt Fig. 5, wo kein Gewinde, aber die Hülse h am Kopf K bezw. K1 in Anwendung ist und eine oder mehrere Seiten der Hülse federartig, wie f verlängert und ausgebogen sind und in die auf N angebrachten Zähne ^ eingreifen.The well-known double-headed core nails have the disadvantage that they have to be specially available for each wall thickness and that after use a lot of time is lost in sorting. In the present invention, this deficiency is eliminated in that one or both heads can be displaced and fixed on the nail. In Fig. 1, 2 and 3 this is arranged such that the one head K 1 , Fig. Ι and 2, or both heads K and K 1 , Fig. 3, respectively between nuts m 1. The purpose for which the nails N are wholly or partially threaded must be established and recorded. In Fig. 4, the nail N is also provided with a thread and so is the displaceable plate K 1 (or also K according to FIG. 3 and K 1 according to FIG. 2), whereby the nuts m 1 (or m) are omitted ; In addition, for better identification at K 1, the cut sleeve h can be, which acts resiliently in such a way and only gives way to a more significant force when moving, also the easy screwing between K or. K 1 and N prevents. From this it follows that the thread can also be absent at all. Yet another way of determining the displaceable head K respectively. .ST 1 shows Fig. 5, where no thread, but the sleeve h on the head K respectively. K 1 is in use and one or more sides of the sleeve are spring-like, like f, are elongated and bent and engage the teeth on N ^.

Patent-Anspruch:Patent claim: Doppelköpfige Kernnägel, deren Köpfe K und ^C1 auf den Schäften N verschiebbar und dadurch feststellbar sind, dafs die mit Gewinde versehenen Schäfte N die Muttern m und m1 tragen, zwischen welchen die Köpfe K bezw. K1 festgeklemmt werden, oder dafs die Köpfe selber mit Gewinde und mit oder ohne hülsen- oder federartigen Ansätzen h versehen sind, oder letztere an den Köpfen ohne Gewinde angebracht und die Nägel N mit Zähnen versehen sind, in welche federartige Verlängerungen f der Hülsen h eingreifen.Double-headed core nails, the heads K and ^ C 1 of which are displaceable on the shafts N and can be determined by the fact that the threaded shafts N carry the nuts m and m 1 , between which the heads K respectively. K 1 are clamped, or that the heads themselves are provided with thread and with or without sleeve or spring-like extensions h , or the latter are attached to the heads without threads and the nails N are provided with teeth, into which spring-like extensions f of the sleeves h intervention.
