Pateritirt im Deutschen Reiche vom 5. December 1879 ab.Paternity in the German Empire from December 5th, 1879.
Dieses Verfahren bezweckt die Herstellung von gegossenen Stahlketten bezw. das Durcheinandergiefsen von Kettengliedern. Es besteht zunächst darin, dafs man mit Hülfe einer Kernbüchse oder Presse Kerne von der Form Fig. 4 aus Formmasse herstellt, und diese Kerne, nachdem sie getrocknet und gebrannt, zu je zweien in eine Formkastenhälfte mit entsprechender Aushöhlung einlegt, wie die Fig. 1, 2 und 3 zeigen. Bevor nun die beiden Formkastenhälften zusammengelegt werden, legt man, je nach Bedürfnifs, vorher einzeln gegossene Kettenglieder, welche man anschliefsen will, in die entsprechenden Aussparungen der Kerne und des Formkastens ein, schliefst beide Hälften, nachdem ein Eingufs in die oberen Kerne geschnitten, vermittelst Keile, und es ist die Form zum Giefsen fertig.The purpose of this process is the production of cast steel chains BEZW. the mess pouring of chain links. It consists first of all in that one can with the help of a core box or press cores of the form Fig. 4 from molding compound, and these cores, after they have been dried and fired, each two are placed in a molding box half with a corresponding cavity, as in FIGS. 1, 2 and 3 show. Before the two halves of the molding box are put together, one puts, Depending on requirements, previously individually cast chain links that you want to connect in the corresponding recesses of the cores and the molding box, closes both halves, after an entrainment cut into the upper cores, wedges are put in place, and it is the shape ready for casting.
Es versteht sich von selbst, dafs man anstatt der speciell zu vorgedachtem Zweck angefertigten eisernen Formkasten, wie die Zeichnung zeigt, auch gewöhnliche Formkasten oder Rahmen benutzen kann, bei denen man die Aushöhlung für die Kerne durch Abformen eines entsprechenden Holzklotzes in Sand herstellt. It goes without saying that instead of those that are specially made for a planned purpose iron molding box, as the drawing shows, also ordinary molding box or Can use frames in which the cavity for the cores is made by molding a corresponding block of wood in sand.
Ebenso ist es selbstverständlich, dafs nach obigem Verfahren auch Ketten ohne Steg hergestellt werden können.It also goes without saying that chains without a web can also be produced using the above process can be.
Als wesentlicher Vortheil bei diesem Verfahren ist, nach Angabe der Erfinder, der Umstand anzusehen, dafs blofs das Modell von einem Viertel des zu giefsenden Kettengliedes behufs Einlegens in die zum Formen der Kerne bestimmte Kernbüchse oder Presse herzustellen ist; ferner, dafs die Herstellung der eigentlichen Gufsformen äufserst rasch, und die Lösung des Gufsstücks aus der Form sehr schnell und leicht bewirkt werden kann, was in Anbetracht des starken Schwindens des Stahls beim Erkalten von sehr grofser praktischer Bedeutung ist.According to the inventors, the essential advantage of this process is the fact to see that only the model of a quarter of the chain link to be cast for the purpose of inserting them into the core box or press intended for shaping the cores is; furthermore, that the production of the actual casting molds is extremely rapid, and the solution of the Gufsstücks from the mold can be effected very quickly and easily, which is in consideration the strong shrinkage of the steel when it cools is of very great practical importance is.
