PATENTAMT.PATENT OFFICE.
Die Herstellung von Celluloi'dbällen erfolgte ursprünglich in der Weise, dafs zwei halbkugelförmige Schalen einfach mit stumpfem Stofs an einander gekittet wurden. Bei diesen Bällen sprangen die beiden Hälften meist jedoch schon nach sehr kurzer Zeit aus einander. Es wurde dem Uebelstande dadurch abzuhelfen gesucht, dafs der Stofs entweder mit einer streifenförmigen Unterlage versehen (Fig. 1), oder dafs die Kugel in mehrere, z. B. vier Sectoren zerlegt und die Vereinigung derselben unter Ueberblattung hergestellt wurde (Fig. 2). Aber auch diese Arten der Verbindung bieten auf die Dauer keine Sicherheit, aufserdem ist die erstgenannte Art nicht controlirbar und überhaupt nicht mit Sicherheit ausführbar, die zweite Art ist umständlich und zufolge der Vermehrung der Verbindungsstellen unnütz theuer. In Anwendnng auf halbkugelförmige Schalen bietet diese letztere Art keine gröfsere Sicherheit als die erstgenannte Verbindung mit streifenförmiger Unterlage; aufserdem verbleibt am Stofs stets eine deutlich abgesetzte Rille, welche das Festsetzen von Schmutztheilen begünstigt. Somit genügen auch diese Arten der Verbindung den Erfordernissen der Praxis nicht.Cellulose balls were originally made in such a way that two hemispherical shells were simply blunted with one another Stofs were cemented to each other. With these balls, the two halves usually jumped but after a very short time each other. It became the evil through it sought to remedy the fact that the fabric was either provided with a strip-shaped base (Fig. 1), or that the ball in several, z. B. divided into four sectors and the union of the same was produced with overlaying (Fig. 2). But also these types of connection offer no security in the long run, and the first-mentioned type cannot be controlled and not at all feasible with certainty, the second type is cumbersome and cumbersome unnecessarily expensive to increase the number of junctions. Applied to hemispherical This latter type does not offer any greater security than the first-mentioned connection with shells strip-shaped base; In addition, there is always a clearly separated groove on the fabric, which favors the establishment of dirty parts. Thus, these types of Connection to the requirements of the practice not.
Mit dem Gegenstande der vorliegenden Patentschrift ist dagegen eine Verbindung geschaffen, welche nicht allein dauernd hält, sondern auch einen derart glatten Stofs beider Ballhälften ermöglicht, dafs der Ball das Aussehen hat, als wäre er aus einem Stück gearbeitet. Die Verbindung kennzeichnet sich dadurch, dafs jede Ballhälfte am Stofs ringsum mit Zähnen versehen, diese Zähne im plastischen Zustande um die Wandstärke nach innen gekröpft und die beiden Hälften dann unter Versetzung der Zähne zusammengesteckt werden, so dafs die Zähne jeder Ballhälfte sich also gegen das Innere der zweiten Ballhälfte legen und ein aufserordentlich inniger Zusammenhang beider Hälften erzielt wird. Durch Anwendung eines geeigneten Bindemittels haften die Zähne an der anderen Ballhälfte fest. Auf der Zeichnung veranschaulicht Fig. 3 die beiden Ballhälften vor dem Zusammenstecken, Fig. 4 nach dem Zusammenstecken.With the subject matter of the present patent specification, however, a connection is created, which not only lasts permanently, but also such a smooth fabric of both Ball halves make it possible for the ball to appear as if it were made from one piece. The connection is characterized by the fact that every half of the ball is provided with teeth all around on the fabric, these teeth in the plastic Get angled inwards by the wall thickness and then the two halves under Shifting the teeth are put together so that the teeth of each half of the ball come together So put against the inside of the second half of the ball and an extraordinarily intimate connection of both halves is achieved. Adhere by using a suitable binding agent the teeth on the other half of the ball. In the drawing, Fig. 3 illustrates the two Ball halves before joining, Fig. 4 after joining.
Die Fig. 5 und 6 veranschaulichen die zur Herstellung der Ballhälften dienende Presse vor und nach erfolgter Pressung.Figures 5 and 6 illustrate the press used to manufacture the ball halves before and after pressing.
Die Presse besteht aus dem Gesenk A und dem Stempel B. Letzterer ist oberhalb der Halbkugel mit einem Ringe C versehen, dessen unterer Rand zahnartig ausgeschnitten ist. Die Stärke der zahnartigen Vorsprünge D ist so bemessen, dafs dieselben mit ihrer äufseren Fläche genau in den oberen cylindrischen Theil α der Form passen. Die Zähne D haben in der Breite zweckmäfsig eine schwach konische Form und sind vortheilhaft ein wenig breiter als die Lücken im Ringe C Letzterer kann selbstverständlich auch aus einem Stück mit dem Stempel bestehen.The press consists of the die A and the punch B. The latter is provided above the hemisphere with a ring C , the lower edge of which is cut out like a tooth. The thickness of the tooth-like projections D is so dimensioned that their outer surface fits exactly into the upper cylindrical part α of the form. The teeth D expediently have a slightly conical shape in width and are advantageously a little wider than the gaps in the ring C. The latter can of course also consist of one piece with the punch.
Die Pressung erfolgt bei plastischem Zustande der Cellulo'idplatte E0 welche auf das Gesenk A gelegt und mittelst des Stempels B in Halbkugelform geprefst wird. Der Rand der Platte, welcher in den cylindrischen Theil α der Form zu liegen kommt, erfährt durch die Zähne D The pressing takes place when the cellulose sheet E 0 is in a plastic state, which is placed on the die A and pressed into a hemispherical shape by means of the punch B. The edge of the plate, which comes to lie in the cylindrical part α of the form, is exposed through the teeth D
des Stempels eine zahnartige Ausbildung, indem dort, wo sich die Zähne des Stempels befinden, Lücken ausgeschnitten werden, während dort, wo die Lücken am Ringe sind, an der Ballhälfte Zähne d stehen bleiben. Diese sind nach Obigem etwas schmäler, als die zwischen denselben entstehenden Lücken.of the punch a tooth-like design in that gaps are cut out where the teeth of the punch are, while teeth d remain on the ball half where the gaps are on the ring. According to the above, these are somewhat narrower than the gaps that arise between them.
Die Ballhälfte wird dann aus der Form herausgenommen, das abgequetschte Material , entfernt, und es werden darauf die Zähne, nachdem sie in einen hinreichend plastischen Zustand versetzt worden sind, um die Wandstärke nach innen gekröpft, wie dies Fig. 3 veranschaulicht. Je zwei Ballhälften werden dann, nach Auftragen eines geeigneten Bindemittels, mit versetzten Zähnen an einander gesteckt, so dafs die Zähne jeder der beiden Ballhälften an der inneren. Fläche der anderen Ballhälfte festhaften. Das Bindemittel wird selbstverständlich derart aufgetragen, dafs auch die Ränder der Ballhälften sich rmt__ginander verbinden.The half of the ball is then removed from the mold, the squeezed-off material , removed, and the teeth are placed on it after they have become sufficiently plastic State have been offset, cranked inward by the wall thickness, as shown in FIG. 3 illustrated. Two halves of the ball are then, after applying a suitable binding agent, butted together with offset teeth, so that the teeth of each of the two halves of the ball on the inside. Attach the surface of the other half of the ball. The binder will of course, applied in such a way that the edges of the halves of the ball also fit together associate.
