Description
Rechen- oder Zählmaschine. Den Gegenstand der Erfindung bildet eine Rechen- oder Zählmaschine, bei welcher in bekannter Weise auf Stäben bewegliche Kugeln verschoben werden können. Derartige Zählmaschinen sind an sich bekannt, jedoch wert die nachstehend beschriebene, in Form eines Pultes ausgeführte 'Maschine eine Reihe von vorteilhaften Veränderungen nach.Calculating or counting machine. The subject of the invention is a Calculating or counting machine, in which in a known manner on rods movable Balls can be moved. Such counting machines are known per se, however worth the machine described below in the form of a desk Series of beneficial changes after.
Auf der Zeichnung ist ein Ansführ ungsbeispiel in drei Abbildungen dargestellt; es zeigt Abb. i eine Vorderansicht, Abb.2 eine Seitenansicht, Abb.3 eine schaubildliche Darstellung. Die Rechenmaschine besteht aus den winkelförmig zusammengestoßenen Leisten a, L, deren winkelförmiger Raum durch beispielsweise zehn in gleichmäßigem Abstand angeordnete Führungsschienen c für die auf den Schienen beweglichen Kugeln d überbrückt wird. Di@@ Schienen c sind teils wagrecht, teils schräg nach vorn geneigt verlegt, wodurch die dem Schüler zur Darstellung kommenden Kugeln d1 bequemer eingesehen werden können. An der Seite der Rechenmaschine sind ein.: oder mehrere Schärfvorrichtungen e zum Anschärfen von Griffeln usw. angeordnet, und es kann so der Schüler auf bequemste Art sein Zeichen- oder Schreibwerkzeug in gebrauchsfähigem Zustand in Ordnung halten, indem er mit der einen Hand die Rechenmaschine festhält, mit der anderen das Schreibwerkzeug über die Schärfvorrichtung e hin und her bewegt. Die Neigungen der Stäbe c haben den weiteren Vorteil, daß der Schüler die RechenmasAhine auch als Vorlagepult nach Art der Abb. i verwenden kann, da zu diesem Zweck vor den schrägen Stäben c eine Längsleiste/' beftstigt ist, welche einem Buch oder Heft ; die Abstützung verleiht, nachdem die Kugeln d, wie in Abb. i dargestellt, auf die «-altrechten Bahni_n hochgeschoben sind. Durch die Schräglage wird das Ablesen aus dem Buch oder Heft wesentlich erleichtert. Bei der beschriebenen Rechenmaschine ist demnach all das erreicht, was der Schüler zum Rechnen und zum Erledigen seiner Hausarbeiten braucht.In the drawing, an example is shown in three figures; it shows Fig. i a front view, Fig.2 a side view, Fig.3 a diagrammatic representation. The calculating machine consists of the angularly butted bars a, L, the angular space of which is bridged by, for example, ten equally spaced guide rails c for the balls d moving on the rails. Di @@ rails c are laid partly horizontally, partly inclined forward, so that the balls d1 that the pupil is about to display can be seen more comfortably. On the side of the adding machine there are one or more sharpening devices for sharpening pens, etc., and the student can thus keep his drawing or writing tools in a usable state in the most convenient way by using the adding machine with one hand holds, with the other moves the writing tool over the sharpening device e back and forth. The inclinations of the rods have c the additional advantage that the student i can RechenmasAhine as a template panel on the type of Fig use as c for this purpose in front of the oblique rods is a longitudinal bar 'is beftstigt / which a book or magazine. the support gives after the balls d, as shown in Fig. Reading from the book or notebook is made much easier by the inclined position. In the case of the calculating machine described, everything is achieved that the student needs to do arithmetic and to do his homework.
