KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Zur Herstellung dieser Hohlkugeln aus Celluloid benutzt man am besten zwei Halbkugeln , welche mittelst eines der bekannten Lösungsmittel für Celluloid zusammengeklebt werden.It is best to use two hemispheres to make these hollow spheres from celluloid which are glued together using one of the well-known solvents for celluloid will.
Diese Halbkugeln werden unter einer gewöhnlichen Schrauben- oder Hebelpresse hergestellt und man benutzt hierzu eine zweitheilige Form aus Holz oder Metall.These hemispheres are made using an ordinary screw or lever press and a two-part form made of wood or metal is used for this.
Fig. 5 der beiliegenden Zeichnung stellt eine derartige Doppelform bei geöffneter Presse im Querschnitt dar. α ist der untere Theil der Form, welche an dem unteren feststehenden Theil der Presse befestigt ist. b ist der innere Theil der Form, welcher sich mit dem beweglichen Theil der Presse aufwärts und abwärts bewegt und genau in den Theil a eingepafst ist.Fig. 5 of the accompanying drawings shows such a double mold in cross section with the press open. Α is the lower part of the mold which is attached to the lower fixed part of the press. b is the inner part of the mold, which moves up and down with the movable part of the press, and is precisely fitted into part a.
Die Construction dieser zweitheiligen Form ist bekannt. Neu dagegen und Gegenstand der vorliegenden Erfindung ist die Anordnung der Platte c, Fig. 5, welche auf irgend eine Weise gegen die Form α geprefst wird, um die eingelegte runde Celluloidfolie d gleichmäfsig an den Rändern festzuhalten. Dieselbe mufs im Durchmesser !um ein Drittel gröfser sein als die gewünschte Kugel.The construction of this two-part form is well known. What is new, however, and the subject of the present invention is the arrangement of the plate c, FIG. 5, which is pressed in some way against the shape α in order to hold the inserted round celluloid film d evenly at the edges. It must be a third larger in diameter than the desired sphere.
Die Platte c wird durch die Spiralfeder / auf die Form α gedrückt (Fig. 5 und 6). Die Platte hat ferner zum Schutz gegen Verschiebung Führungsleisten g. The plate c is pressed onto the shape α by the spiral spring / (FIGS. 5 and 6). The plate also has guide strips g to protect against displacement.
Ohne Anordnung der Platte c würde sich die runde Celluloidfolie in unzähligen Falten in die untere Form einpressen, statt eine glatte Halbkugel von gleichmäfsiger Dicke zu ergeben. . ~Without the arrangement of plate c , the round celluloid film would be pressed into the lower mold in innumerable folds instead of producing a smooth hemisphere of uniform thickness. . ~
Fig. 6 stellt die Form bei geschlossener Presse, also bei vollendeter Pressung vor; a und b sind die beiden Hälften der Form und d die Celluloidfolie, welche sich zwischen a und b eingeprefst hat, also eine Halbkugel bildet.6 shows the shape when the press is closed, that is to say when the pressing is completed; a and b are the two halves of the mold and d is the celluloid film, which is pressed in between a and b, i.e. forms a hemisphere.
Die Platte c wurde während der Pressung durch die Spiralfeder f gegen die Form α geprefst und die Spiralfeder f ist nun zusammengedrückt. The plate c was pressed against the shape α by the spiral spring f during the pressing and the spiral spring f is now compressed.
Beim Oeffnen der Presse hebt sich zuerst der Theil b, bis die Spiralfeder / entlastet ist; dann hebt sich auch die Platte c und gestattet ein Herausnehmen der Halbkugel d, welche nun fertig ist.When the press is opened, part b rises first until the spiral spring / is relieved; then the plate c also rises and allows the hemisphere d to be removed, which is now ready.
Nachdem die Halbkugeln auf diese Weise geprefst sind, erübrigt noch das Vereinigen je zweier Halbkugeln zu einer Kugel. Da hierzu ein einfaches Zusammenkitten wenig haltbar sein würde, wird zur Verstärkung ein Celluloidstreifen benutzt, welcher ins Innere der Kugel geklebt wird. Die Breite des Streifens (h, Fig. 1) beträgt am besten Y10 des Durchmessers der Kugel, und die Länge des Streifens entspricht ihrem Umfang. Der Streifen wird zuerst an der einen Halbkugel k festgeklebt (Fig. \i) und dann die andere Halbkugel (k, Fig. 3) angekittet.After the hemispheres have been pressed in this way, it is not necessary to combine two hemispheres into one ball. Since a simple cementing together would not be durable, a celluloid strip is used for reinforcement, which is glued inside the ball. The width of the strip (h, Fig. 1) is best Y 10 of the diameter of the sphere, and the length of the strip corresponds to its circumference. The strip is first glued to one hemisphere k (Fig. \ I) and then cemented to the other hemisphere (k, Fig. 3).
Aufserdem können die Halbkugeln auch über eine entsprechend kleinere innere Kugel gekittet werden, Fig. 2 und 4. Die Innenkugel (m, Fig. 2) ist aus zwei Halb kugeln zusammengesetzt, über welche nun die zwei äufseren Halbkugeln gekittet werden (0, Fig. 2 und 4). Hierbei ist zu beachten, dafs die Berührungslinie der beiden äufseren Halbkugeln In addition, the hemispheres can also be cemented over a correspondingly smaller inner sphere, Fig. 2 and 4. The inner sphere (m, Fig. 2) is composed of two hemispheres, over which the two outer hemispheres are now cemented (0, Fig. 2 and 4). It should be noted here that the line of contact between the two outer hemispheres
