KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die bekannten Lithophanieen sind geprefste Bildwerke aus getrübtem Glas oder Porcellan, bei denen die Wirkung des durchscheinenden Lichtes infolge der in geeigneter Weise abgestuften Dicke des Materials in entsprechender Licht- und Schattenvertheilung zur Geltung kommt.The well-known lithophanes are pressed sculptures made of clouded glass or porcelain, in which the effect of light shining through as a result of being appropriately graded Thickness of the material in the appropriate light and shadow distribution to its best advantage comes.
Solche Lithophanieen haben die Eigenschaft, dafs sie nur bei durchscheinendem Licht wirken. WTenn also beispielsweise Abends die Fenster, in denen ein solches Bildwerk aufgestellt ist, von aufsen geschlossen werden, so dafs es nur vom Zimmer aus Licht erhält, so verliert es überhaupt jede Wirkung.Such lithophanes have the property that they act only when light is shining through. W hen T So for example, evening the windows in which such an image work is set to be closed from without, it only DAF from the room receives light, it loses any effect whatsoever.
Der Gegenstand der vorliegenden Erfindung besteht nun darin, dafs die Vorderseite, d. h. die dem Beschauer zugekehrte Seite des Bildwerkes vorzugsweise als negatives oder concaves Relief ausgearbeitet wird. Es ist bekannt, dafs ein negatives Relief bei schräg auffallendem Licht ebenso wirkt, wie ein positives Relief, welches von der entgegengesetzten Seite Licht erhält.The object of the present invention is that the front side, i.e. H. the side of the picture facing the viewer preferably as negative or concave Relief is worked out. It is known that a negative relief in an oblique relief Light has the same effect as a positive relief, which is light from the opposite side receives.
Die Rückseite des Bildwerkes wird nun im wesentlichen als positives Relief ausgearbeitet, und zwar derart, dafs die Materialstärken an allen Stellen für durchscheinendes Licht der angestrebten Licht- und Schattenwirkung entsprechen, ebenso wie dies bei den gewöhnlichen Lithophanieen geschieht.The back of the picture is now essentially worked out as a positive relief, in such a way that the material thicknesses at all points for light shining through correspond to the desired light and shadow effect, as well as the usual Lithophany happens.
Das Ergebnifs ist folgendes:The result is the following:
Das Licht, welches von hinten auf das Bildwerk geworfen wird, dringt durch die verschieden dicke Materialschicht hindurch und bringt dadurch die gewöhnliche Wirkung der bekannten Lithophanie zu Stande, während man bei auffallendem Lichte eine Reliefwirkung erzielt.The light that is thrown from behind on the picture penetrates through the different thick layer of material through it and thereby brings about the usual effect of the well-known lithophane, while a relief effect is achieved when the light is striking.
Soll die dem Beschauer zugekehrte Seite des Bildwerks convex gemacht werden, so kann die beschriebene Wirkung ebenfalls zu Stande kommen, wenn bei der Vertheilung und Abmessung der vorkommenden Concavitäten mit künstlerischer Auswahl verfahren wird.If the side of the picture facing the viewer is to be made convex, then the described effect also come about when in the distribution and dimensioning the concavities that occur are treated with artistic selection.
