Description

Lineal, das als Zeichenwinkel, Zirkel, Rechenschieber und Schublehre benutzbar ist. Die Erfindung bezweckt, in einer Taschenform die nötigsten Instrumente zu vereini.9en, welche ein Techniker für seine tägliche Arbeit, wie Skizzieren, Entwerfen, Berechnen und einfache Messungen, braucht. Dementsprechend stellt das Gerät gemäß der Erfin; dung eine Kombination aus einem Lineal, einem Zirkel, der auch als Winkel un;d Transporteur benutzt werden kann, einem Rechenschieber und einer Schublehre dar.Ruler that acts as a drawing square, compass, slide rule and slide rule is usable. The invention aims to provide the most necessary instruments in a pocket shape to unite 9 which a technician uses for his daily work, such as sketching, Designing, calculating, and simple measurements, needs. Accordingly, the Device according to the invention; a combination of a ruler, a pair of compasses, the Can also be used as an angle and feed dog, a slide rule and a calliper.

Wie die Abbildung zeigt, besteht das Gerät aus einem Lineal a, das eine abklappbare Zunge b, einen Läufer e und Maßeinteilungen, besitzt. Die Zunge b ist zur Bildung ,einer Schublehrd vorgesehen, während der Läufer und das Lineal selbst die üblichen Teile eines Rechenschiebers darstellen. Die Maßeinteilungen dienen teilweise zu Meßzwecken, teilweise bilden sie die verschiedenen Skalen enitves Rechenschiebers.As the figure shows, the device consists of a ruler a, the has a foldable tongue b, a runner e and graduations. The tongue b is provided for the formation, a slide gauge, while the runner and the ruler even represent the usual parts of a slide rule. The graduations serve partly for measuring purposes, partly they form the different scales enitves Slide rule.

In dem Lineal gleitet der Teil c, der als ein Zirkel mit flachen Schenkeln und dem Drehgelenk /ausgebildet ist. Dieser Teil trägt auch eine abklappbare Zungeid und kann mit entsprechenden - Skalen entweder als die Zunge des Rechenschiebers, als Zirkel, als Winkel, als Transporteur oder als beweglicher Teil der Schublehre benutzt werden. Die Spitzenstäbe s des Zirkels können in die Schenkel eingeschoben werden.Part c slides in the ruler, which is designed as a compass with flat legs and the swivel joint / . This part also has a foldable tongue and can be used with appropriate scales either as the tongue of the slide rule, as a compass, as an angle, as a conveyor or as a movable part of the slide rule. The top rods s of the compass can be pushed into the legs.
