KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren zur Herstellung von Stecknadeln, bei welchem die Köpfe dadurch hergestellt werden, dafs die oberen Enden der Nadelschäfte durch Eintauchen in ein elektrisches Schweifsbad flüssig gemacht werden und die hierbei entstehenden flüssigen Metalltropfen nach dem Erkalten die Nadelköpfe bilden.The subject of the present invention is a process for the production of pins, in which the heads are made by dipping the upper ends of the needle shafts into an electric Tail bath are made liquid and the resulting liquid metal droplets form the needle heads after cooling.
Dieses Verfahren besitzt den wesentlichen Vortheil, dafs mit einem Male an einer grofsen Anzahl von Nadelschäften die Köpfe hergestellt werden können und den Köpfen ohne Weiteres jede beliebige Dicke gegeben werden kann.This procedure has the essential advantage that at once it is one great Number of needle shafts the heads can be made and the heads easily any thickness can be given.
In der beiliegenden Zeichnung zeigt:The attached drawing shows:
Fig. ι die Vorderansicht undFig. Ι the front view and
Fig. 2 die Seitenansicht einer Einrichtung zum Fassen einer gröfseren Anzahl von Nadeln, an deren eingetauchten Enden sich die Köpfe bilden.2 shows the side view of a device for gripping a large number of needles, the heads form at the immersed ends.
Es soll jedoch die dargestellte Einrichtung nur als Beispiel gelten, da dieselbe in verschiedener Weise ausgeführt sein kann.However, the device shown is only intended as an example, since the same in different Way can be executed.
Die Nadelschäfte a werden zwischen mehreren auf einander liegenden Schienen b in Reihen festgeklemmt und mit ihren Kopfenden in ein Schweifsbad getaucht, in welchem die Schmelzhitze dadurch erzeugt wird, dafs die die Nadeln haltenden, von dem Griff isolirten Platten b mit dem negativen Pol der Stromquelle verbunden sind, während der positive Pol in die das Schmelzbad bildende Soda- oder andere dem Zweck entsprechende Lösung geführt ist. An den Stellen, wo die Nadelschäfte stecken, sind die Schienen mit Rillen von geringer Tiefe versehen, um die Schäfte in der gewünschten Lage festzuhalten.The needle shafts a are clamped in rows between several rails b lying one on top of the other, and their heads are immersed in a tail bath in which the heat of fusion is produced by connecting the plates b holding the needles and insulated from the handle to the negative pole of the power source while the positive pole is led into the soda or other appropriate solution that forms the molten bath. At the points where the needle shafts stick, the rails are provided with grooves of shallow depth in order to hold the shafts in the desired position.
