KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Gegenstand der vorliegenden Erfindung ist ein Vorhalter bei Nietmaschinen, welcher es ermöglicht, Profileisen von gewissen Formen, beispielsweise U-Eisen, welche nur eine geringe Breite besitzen, zu nieten. Bei den bisher bekannten Vorhaltern verhinderte das Futter, in welches der Vorhalter eingesteckt ist, dafs man U-Eisen von weniger grofsen Dimensionen zwischen den Vorhalter und den Stempel einlegen konnte. Um diesen Uebelstand zu beseitigen, hat das Futter bezw. der Vorhalter an seinem vorderen Ende eine Kröpfung erhalten, über welche das U-Eisen auch von geringer Breite derart gelegt werden kann, dafs eine Nietung' an den seitlichen Flantschen stattfinden kann.The subject of the present invention is a pre-holder in riveting machines, which it enables profile iron of certain shapes, for example U-iron, which only have a small Own width to rivet. With the previously known feeders, the feed prevented into which the pre-holder is inserted, that U-irons of less large dimensions can be used could insert between the pre-holder and the stamp. To remedy this evil, has the feed respectively. the front holder has a crank at its front end, over which the U-iron can be placed, even of a small width, in such a way that a riveting 'can take place on the side flanges.
Die beiliegende Zeichnung veranschaulicht den Erfindungsgegenstand.The accompanying drawing illustrates the subject matter of the invention.
An dem Bügel α ist das Futter in bekannter Weise angebracht. An seinem vorderen Theile besitzt das Futter eine Kröpfung b, welche den Vorhalter c aufnimmt. Ueber diese Kröpfung kann das U-Eisen, wie in der Zeichnung dargestellt, bequem vor den Vorhalter geschoben werden, so dafs die Nietmaschine sich auch für U-Eisen von geringer Breite verwenden lä'fst. Für die verschiedenen Nietkopfdimensionen hat man nur nöthig, den Vorhalter c aus dem Futter b herauszunehmen und durch einen anderen zu ersetzen. Selbstverständlich kann auch das Futter b mit dem Vorhalter c aus einem Stück bestehen, so dafs behufs Auswechselung des Vorhalters für eine andere Nietkopfdimension der Vorhalter aus der Halte hülse d (Fig. 2) herausgezogen und ausgewechselt werden mufs.The lining is attached to the bracket α in a known manner. On its front part the lining has a crank b which receives the holder c. As shown in the drawing, the U-iron can be pushed comfortably in front of the pre-holder via this crank, so that the riveting machine can also be used for U-iron of narrow width. For the various rivet head dimensions, it is only necessary to remove the pre-holder c from the chuck b and replace it with another. Of course, the chuck b with the pre-holder c can also consist of one piece, so that in order to replace the pre-holder for a different rivet head dimension, the pre-holder must be pulled out of the holding sleeve d (FIG. 2) and replaced.
