KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Zeigerwage der bekannten Art, bei welcher der Schalenträger durch Kugeln oder andere Rollkörper in seitlichen, runden oder winkligen Gleitschienen des Trägers senkrecht geführt wird. Die Erfindung besteht darin, daß die Kugeln o. dgl. Rollkörper auf nachgiebigen Lagern, z. B. schwachen Federn oder freischwingenden kleinen Gewichtshebeln, ruhen und so in ίο der Schwebe erhalten werden.The invention relates to a pointer carriage of the known type, in which the shell support by balls or other rolling elements in lateral, round or angled slide rails of the carrier is guided vertically. The invention consists in that the balls o. The like. Rolling body on flexible bearings, z. B. weak springs or free-swinging small weight levers, rest and so in ίο the levitation be maintained.

Während bei den Wagen mit von parallelen Stangen geführtem Schalenträger die Bewegung des letzteren nicht genau senkrecht und mit beträchtlicher Zapfenreibung erfolgt, ist die Führung des Trägers nach vorliegender Erfindung genau senkrecht und die die richtige Gewichtsangabe beeinträchtigende Reibung geringer. Die nachgiebige Unterstützung der Kugel hält diese in der Schwebe, was notwendig ist, da der Schalenträger mit Spielraum zwischen den Kugeln gleiten muß, und hindert dieselbe nicht an der rollenden Bewegung, wie wenn die Kugel auf einem festen Körper läge. Zudem wird durch die neue Führung des Schalenträgers an Material, Raum und Gewicht gespart.
Auf der Zeichnunng ist:
Fig. ι eine hintere Ansicht der offen gelegten Wage.
While in the car with the shell carrier guided by parallel rods the movement of the latter is not exactly vertical and with considerable pin friction, the guidance of the carrier according to the present invention is exactly vertical and the friction impairing the correct weight specification is lower. The resilient support of the ball keeps it in suspension, which is necessary because the shell support must slide with clearance between the balls, and does not prevent the same from rolling as if the ball were lying on a solid body. In addition, the new guidance of the tray carrier saves material, space and weight.
On the drawing is:
Fig. Ι a rear view of the disclosed balance.

Fig. 2 und 3 zeigen zwei Kugelführungen in senkrecht zueinander gedachten Schnitten. Fig. 4 stellt eine Abänderungsforfn der Führung dar.2 and 3 show two ball guides in imaginary sections perpendicular to one another. Fig. 4 illustrates a modification of the guide.

Der Schalenträger α ist mittels der an das Querstück b desselben angreifenden Federn c, c im Gehäuse d aufgehängt und an den Seiten mit Rillen e versehen. Neben dem Schalenträger sind im Gehäuse rinnenartige Führungsschienen f,f befestigt, welche Vorsprünge g aufweisen. Auf diesen ruhen Federn h, welche Kugeln i tragen. Der Schalenträger hat bei seinen Bewegungen daher nur den Widerstand der nachgiebigen Lagerung der Kugeln zu überwinden.The shell support α is suspended in the housing d by means of the springs c, c acting on the crosspiece b thereof and provided with grooves e on the sides. In addition to the shell carrier, channel-like guide rails f, f , which have projections g , are fastened in the housing. Springs h, which carry balls i , rest on these. The shell carrier therefore only has to overcome the resistance of the resilient mounting of the balls during its movements.

Nach der in Fig. 4 dargestellten Ausführungsform ruht die Kugel i auf dem kurzen Arm eines an der Schiene / schwingbar gelagerten, ein Gewicht / tragenden Winkelhebels k. Die Lagerung der Kugeln ist auch in diesem Falle nachgiebig und verursacht eine kaum nennenswerte Reibung.According to the embodiment shown in FIG. 4, the ball i rests on the short arm of a weight / bearing angle lever k which is pivotably mounted on the rail. The bearing of the balls is also flexible in this case and causes hardly any friction worth mentioning.

An Stelle der Kugeln können mit gleichem Erfolge auch andere Rollkörper, wie glatte oder profilierte Scheiben oder Walzen Verwendung finden, ohne daß der Erfindungsgedanke beeinflußt wird.Instead of the balls, other rolling bodies, such as smooth ones, can also be used with the same success or profiled disks or rollers are used without affecting the inventive concept being affected.
