Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Dieses Werkzeug besteht in seinen Hauptbestandtheilen aus zwei Stäben (s. Fig. 1), welche neben einander liegen und auf der Grenze des ersten und zweiten Dritttheils durch ein Schlofs bezw. durch den im Mittelpunkt dieses Schlosses befindlichen Schlufsstift drehbar mit einander verbunden sind.This tool consists in its main parts of two rods (see Fig. 1), which lie next to each other and on the border of the first and second third parts through a castle or rotatable by the key pin located in the center of this lock are connected to each other.
Die längeren Schenkel α dieser Stäbe dienen dazu, die zu messenden Leder zu überfassen, die beiden kürzeren Schenkel b dagegen zunächst als Handhabe. Indem man beide mit der rechten Hand so überfafst, dafs der Daumen auf der Schutzdecke c, Fig. 2, die den als Zeiger dienenden Hebel d bedeckt, liegt, zwingt man durch schwachen Druck die längeren Schenkel α so weit aus einander, dafs solche den zu messenden Gegenstand aufnehmen können.The longer legs α of these rods serve to cover the leather to be measured, while the two shorter legs b initially serve as a handle. By grasping both with the right hand in such a way that the thumb lies on the protective cover c, Fig. 2, which covers the lever d serving as a pointer, the longer legs α are forced apart by slight pressure from one another so that these are the can record the object to be measured.
Will man nun z. B. die Stärke des Schildes oder des Halses der Leder, welche dessen Werth hauptsächlich mitbestimmen, die sich aber bis jetzt, ohne die Leder zu zerschneiden, nicht hat feststellen lassen, ermitteln, so schiebt man die längeren Schenkel.α so weit über die zu messenden Leder, bis die an den Enden dieser Schenkel befindlichen Tastknöpfe die betreffenden Stellen erreicht haben; läfst nun der Druck der Hand nach, so werden die Enden der längeren Schenkel b durch die zwischen den beiden kürzeren Schenkeln befindliche Spreizfeder e zusammengeprefst, und eine Querschiene f, welche mit ihrem einen Ende mit einem der kürzeren Schenkel a, mit dem anderen Ende mit dem als Zeiger dienenden ungleicharmigen Hebel d drehbar verbunden, leitet nun den Hebel so, dafs dessen Spitze die Stärke des zwischen , den Tastenden befindlichen Leders auf der unter der Zeigerspitze liegenden Theilung (Scala) g anzeigt. Infolge der Lage des Drehpunktes in dem Hebel wird das Ergebnifs der Messung vergröfsert angegeben, und zwar so, dafs eine Theilstrecke von 3 cm auf der Theilung nur ι cm wirklicher Lederstärke ausmacht, die Stärke der'zu messenden Leder-sich also um so genauer feststellen läfst.If you want to z. If, for example, the thickness of the shield or the neck of the leather, which mainly determines its value, but which has not yet been determined without cutting the leather, one pushes the longer legs. α so far over the leather to be measured until the buttons located at the ends of these legs have reached the relevant points; If the pressure of the hand now subsides, the ends of the longer legs b are pressed together by the expanding spring e located between the two shorter legs, and a transverse rail f, which with one end with one of the shorter legs a, with the other end with rotatably connected to the unequal-armed lever d serving as a pointer, now guides the lever in such a way that its tip indicates the thickness of the leather between the probe ends on the graduation (scale) g below the pointer tip. As a result of the position of the fulcrum in the lever, the result of the measurement is given enlarged, in such a way that a section of 3 cm on the division is only ½ cm of real leather thickness, so the thickness of the leather to be measured is all the more precisely determined running.
Die über dem Hebel liegende Schutzdecke c, Fig. 2, verhindert, dafs bei unvorsichtiger Handhabung eine Störung der Wirkungen des Hebels stattfindet. The protective cover c, FIG. 2, which lies over the lever, prevents the effects of the lever from being disturbed if handled carelessly.
, Das Werkzeug hat eine Länge von 91 cm und eine Sperrweite von 1,2 cm, so dafs sich damit schwache Geschirr- und Brandsohlleder, sowie auch starke Sohl- und Riemenleder messen lassen., The tool has a length of 91 cm and a locking width of 1.2 cm, so that thus weak harness and insole leather, as well as strong sole and strap leather let measure.
