PATENTAMT.PATENT OFFICE.
Die Rechenmaschine besteht aus einem etwa 4,60 m langen und 1 cm starken Eisendraht, welcher so gebogen ist, dafs er einen senkrechten und fünf waagrechte Stäbe bildet. Die beiden Enden des Drahtgestelles sind bei a und b mit tiefen Schraubengewinden versehen und in Holzklötze eingeschraubt.The calculating machine consists of an iron wire about 4.60 m long and 1 cm thick, which is bent so that it forms one vertical and five horizontal bars. The two ends of the wire frame are provided with deep screw threads at a and b and screwed into wooden blocks.
Auf dem senkrechten Stabe e und dem untersten waagrechten Stabe d ruhen je 10 Kugeln, welche einen Durchmesser von 6 cm haben und behufs guten Laufes auf dem Gestell an den Enden ausgehöhlt sind (s. Fig. 2). Durch diese Aushöhlung verlieren die Kugeln an dem Durchmesser ihrer Höhe 3/4 cm.On the vertical bar e and the lowest horizontal bar d each rest 10 balls, which have a diameter of 6 cm and are hollowed out at the ends for good running on the frame (see Fig. 2). By weakening the balls losing the diameter of its height 3/4 cm.
Fig. ι zeigt die Ansicht der Maschine vom Standpunkt des Lehrers.Fig. Ι shows the view of the machine from the teacher's point of view.
Die beiden Holzklötze, in welchen sich die beiden Enden α und b des Drahtgestelles befinden, sind durch ein Bodenbrett mit einander verbunden. An der hinteren Kante dieses Bodenbrettes ist ein circa 12 cm breites, aufrecht stehendes Brett und auf diesem ein flach aufliegendes Deckbrett zu 2/8 Breite des Bodenbrettes befestigt, jedoch nur bis etwa 7 bis 8 cm vor der Biegung des untersten Drahtstabes behufs Durchgangs der Kugeln. Auf diese Weise wird durch die eben beschriebenen Bretter ein Kasten gebildet, der nur nach der Seite des Lehrers zu offen, für die Kinder jedoch verschlossen ist, so dafs diese die auf dem waagrechten Stabe d ruhenden Kugeln nicht sehen können. Aehnlich ist es mit den Kugeln auf dem. senkrechten Stabe c. Auch hier stehen die Kugeln in einem Kasten, welcher dem Lehrer zu offen, für die Kinder jedoch verschlossen ist. . Die Kinder können somit nur diejenigen Kugeln sehen, mit welchen der Lehrer auf dem Gestell operirt, und die ganze Aufmerksamkeit der Kinder ist nur einzig und allein auf diese gerichtet.The two wooden blocks in which the two ends α and b of the wire frame are located are connected to one another by a floor board. At the rear edge of this floor board is approximately 12 cm wide, upright board and attached to a flat resting deck board to 2/8 width of the bottom board on this, but only to about 7 cm to 8 prior to the bending of the lowermost wire bar behufs passage of the balls . In this way a box is formed by the boards just described, which is only too open on the teacher's side, but closed to the children so that they cannot see the balls resting on the horizontal bar d. It is similar with the balls on the. vertical bar c. Here, too, the balls are in a box that is too open for the teacher, but locked for the children. . The children can therefore only see those balls with which the teacher operates on the stand, and the children's whole attention is directed solely to these.
Fig. 4 macht ersichtlich, dafs zum guten Tragen an beiden Enden der Maschine ein Paar Handgriffe angebracht sind.Fig. 4 shows that a good wearing at both ends of the machine Few handles are attached.
