Das neue Verfahren besteht darin, Nähnadeln aus gehärtetem Stahldraht herzustellen, indem man den mittleren Theil eines für zwei Nadeln bezw. eine Haarnadel bestimmten Stahldrahtes ausglüht, um an dieser Stelle die Augen der Nähnadeln auszustanzen bezw. die Haarnadel biegen zu können.The new process consists in making sewing needles from hardened steel wire, by the middle part of one for two needles respectively. a hairpin made of certain steel wire anneals to punch out the eyes of the sewing needles or at this point. the hairpin to be able to bend.
Bisher hat der Fabrikant zur Herstellung von Nadeln nur weichen ungerichteten Stahldraht verwendet, und es war daher seine erste Aufgabe, den in der Länge von zwei Nadeln geschnittenen Draht zu richten, damit derselbe, auf der Spitzenschleifmaschine von beiden Seiten geschliffen werden konnte. Dann wurden die Augen gestanzt, die beiden Nadeln getrennt und endlich gehärtet. Das Härten geschah · in einem gewöhnlichen Glühofen auf Platten, worauf die Nadeln in OeI abgelassen, wurden. Diese Fabrikationsweise ist sehr umständlich und dem Härten des Drahtes insofern hinderlich, als sich die einzelnen Nadeln leicht verziehen.So far, the manufacturer has only had soft, non-directional steel wire for the production of needles used, and it was therefore his first job to use the one the length of two needles cut wire to be straightened so the same, on the top grinder of both Sides could be sanded. Then the eyes were punched, the two needles separated and finally hardened. The hardening took place in an ordinary annealing furnace Plates, after which the needles were drained into oil. This manufacturing method is very cumbersome and the hardening of the wire is a hindrance to the extent that the individual needles are easily warped.
; Durch das neue Verfahren wird nun die Herstellung von Nadeln wesentlich vereinfacht dadurch, dafs man schon mit Beginn der Fabrikation gehärteten Stahldraht in Anwendung bringen kann. ; With the new process, the manufacture of needles is now considerably simplified, in that hardened steel wire can be used right from the start of manufacture.
Der in der Länge von zwei Nadeln gesuhniutne hnrie Sinhldraht wird, von der ^ipiti'.c.-ny.rlilcitmaschine kommend, mit seinem nnnicren Ί heile, der nur für die Augen und k.·: ;c der beiden Nadeln bemessen ist, über c;;:e W arn^cqudic g^iühn und so nur dieser Theil des Stahldrahtes ausgeglüht. Dann werden die Augen ausgestanzt, die beiden Nadeln getrennt und ihre Köpfe abgeschliffen.The wholesaled in the length of two needles hnrie Sinhldraht, coming from the ^ ipiti'.c.-ny.rlilcitmaschine, is with his nnnicren Ί heal that only for the eyes and k. ·:; c of the two needles is sized over c ;;: e W arn ^ cqudic g ^ iühn and so only this one Part of the steel wire annealed. Then the eyes are punched out, the two needles separated and their heads abraded.
Der Apparat, welchen Erfinder zur Ausführung dieses Verfahrens benutzt, ist auf beiliegender Zeichnung in Fig. ι in Vorderansicht, in Fig. 2 in Seitenansicht dargestellt.The apparatus which the inventor uses to carry out this process is shown in the accompanying sheet Drawing in Fig. Ι in front view, shown in Fig. 2 in side view.
Der Apparat besteht aus zwei mit Riffeln versehenen Scheiben C C, welche mit ihren Riffeln die Drähte aus einem Auflegekasten D nehmen und dieselben über ein oder mehrere Brennerrohre A führen, welche mit einem Gemenge von Gas und Luft gespeist werden.'The apparatus consists of two corrugated disks CC, which with their corrugations take the wires from a lay-on box D and lead them over one or more burner tubes A , which are fed with a mixture of gas and air. '
Damit nun die Flammen nur den mittleren Theil des Drahtes, welcher für die Augen der Nadel bestimmt ist, ausglühen, sind an den Seiten der Gasrohre zwei Schutzbleche B B in gleicher Höhe mit den Scheiben C angebracht, um zu verhindern, dafs die Flam-, men einen weiteren Theil des Drahtes bestreichen. Die Scheiben C C müssen bei starkem Draht, damit derselbe genügend ausgeglüht wird, durch partielle Zahnräder oder durch Hebelwerk in ruckweise Rotation versetzt werden, feinerer Draht wird jedoch schon bei entsprechend langsamer Rotation der Scheiben, welche durch Stufenscheiben reguliri werden kann, gänzlich ausgeglüht. Bei e lassen die Scheiben CC den Dniht nach erfolgter Erweichung in einen Kasten E zur limgsiunen Erkaltung fallen, aus welchem derselbe dünn zu weiterer Verarbeitung genommen wird.So that the flames burn out only the central part of the wire, which is intended for the eyes of the needle, two protective plates BB are attached to the sides of the gas pipes at the same height as the washers C , in order to prevent the flames from burning brush another part of the wire. In the case of thick wire, the CC disks have to be set in jerky rotation by partial gear wheels or a lever mechanism in order to ensure that the wire is sufficiently annealed, but finer wire is completely annealed with a correspondingly slow rotation of the disks, which can be regulated by stepped disks. At e , the slices CC let the thin, after it has softened, fall into a box E to cool it down, from which it is taken thinly for further processing.
