Description
Die Drahtstäbe sind zu dreien gruppirt. Dies hat vornehmlich den Hauptzweck für das Numeriren, ein vollkommenes und übersichtliches Bild einer mehrstelligen Zahl darstellen zu können.The wire rods are grouped in threes. This has primarily the main purpose for numbering, to present a perfect and clear picture of a multi-digit number can.
Zu dem Zwecke ist die Aufstellung des Rechenbrettes in senkrechter Richtung der Drähte gewählt und zum Festhalten der ein Zahlenbild darstellenden Kugeln ein Federmechanismus angebracht. Derselbe besteht aus einem Brettchen von der Länge des Rahmens der Maschine, über welches in der Quere nach den entsprechenden Abständen der Drähte und deren Gruppirung Federn befestigt sind, welche in ihrer Längenrichtung einem vertical ausgeübten Drucke nachgeben. Die Befestigung der Federn ist folgendermaafsen bewirkt: An ihren Enden sind dieselben mit einer 1,25 mm breiten und 6 mm langen Oeffnung versehen. Durch dieselbe ist nach den Enden der Federn zu ein Schräubchen mit ziemlich glattem und breitem Kopfe in das Federbrett eingelassen und zwar ohne jegliche Pressung der Feder, so dafs dieselbe durch das Schräubchen nicht an das Federbrett geklemmt und also immer in ihrer natürlichen Lage gehalten wird, somit von beiden Seiten leicht einem von der Richtung ihrer Enden ausgehenden Drucke nachgiebt. Wird nun das Federbrett rechtwinklig zu der Richtung der Drähte an beiden Seiten in den Rahmen eingelassen, so dafs die Federn mit dem Gipfelpunkte ihrer Krümmung die Drähte berühren, so können die Kugeln ebenso leicht vorbeigeschoben, als auch sicher und fest von der Feder getragen werden.For this purpose, the calculation board is set up in the vertical direction of the wires selected and attached a spring mechanism to hold the balls representing a number picture. It consists of a board the length of the frame of the machine, about which in the cross according to the appropriate distances of the wires and their Grouping of feathers are attached, which in their lengthwise direction a vertical exerted Give in to prints. The fastening of the springs is effected as follows: At their ends they are provided with an opening 1.25 mm wide and 6 mm long. By towards the ends of the feathers it is a little screw with a fairly smooth and broad one Head let into the feather board without any compression of the feather, so that the same not clamped to the spring board by the screw and therefore always in its natural state Position is held, thus from both sides easily one proceeding from the direction of their ends Gives way to prints. If the spring board is now embedded in the frame at right angles to the direction of the wires on both sides, so that the springs touch the wires with the apex of their curvature, the balls can just as easily be pushed past, as well as being carried safely and firmly by the spring.
