KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Ausbildung des Verfahrens nach dem Hauptpatent betrifft die Herstellung
von Doppelknöpfen aus Celluloid, wie sie für Hemden und dergl. Verwendung finden.
Solche Knöpfe sind bisher aus Knochen auf der Drehbank hergestellt worden und in einzelnen
Fällen wohl auch aus Celluloid gedreht worden und waren der Arbeit entsprechend teuer.
Durch Herstellung dieser Knöpfe nach dem vorliegenden Verfahren werden dieselben in
weit billigerer Weise erzeugt. Es hat sich herausgestellt, daß die Schmiegsamkeit des
Celluloids in erwärmtem Zustande eine solche ist, daß es nicht nur den dünnen Zwischenraum
ausfüllt, der dann die Wand einer Öse bildet, sondern daß auch auf dieselbe Weise
ein massiver Schaft erzeugt werden kann. Es müssen dann entsprechend dickere Platten von
Celluloid von Anfang an genommen werden, da die so erzeugten Doppelknöpfe einen bei
weitem erheblicheren Materialaufwand ihrer Größe halber bedingen.The present embodiment of the method according to the main patent relates to the production of double buttons from celluloid, as they are used for shirts and the like.
Such buttons have previously been made from bones on the lathe and in some cases probably also turned from celluloid and were correspondingly expensive to work. By making these buttons in accordance with the present process, they are made in a far cheaper manner. It has been found that the pliability of the celluloid in a heated state is such that it not only fills the thin space which then forms the wall of an eyelet, but that a solid shaft can also be produced in the same way. Correspondingly thicker sheets of celluloid then have to be used from the beginning, since the double buttons produced in this way require a far more substantial amount of material due to their size.
Die neue Vorrichtung besteht demnach aus drei Formplatten unter Wegfall der Dorne.The new device therefore consists of three mold plates with omission of the mandrels.
Die eine Formplatte trägt den Fuß des Doppelknopfes, die mittlere eine Höhlung, die dem Schaft des Doppelknopfes entspricht, und die obere eine Höhlung, die dem Kopf des Doppelknopfes entspricht.One shaped plate bears the foot of the double button, the middle a cavity, the corresponds to the shaft of the double button, and the upper one has a cavity that corresponds to the head of the Corresponds to the double button.
Bei der Herstellung derartiger Doppelknöpfe sind die geschlossenen Platten, wie sie in dem Patent 138572 dargestellt sind, nicht mehr verwendbar.In the manufacture of such double buttons, the closed panels are as shown in the Patent 138572 are no longer usable.
