Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist ein MikroIndikator mit kleinem Hub für hohe Tourenzahlen, welcher sich von den bekannten Apparaten seiner Art dadurch unterscheidet, daß der in bekannter Weise von einer Feder gehaltene ,Kolben des mit dem Maschinenzylinder in Verbindung stehenden Druckzylinders auf seinem oberen Ende einen Teller trägt, auf welchem das dicke, mit einem Schreibstift versehene Ende einer durch eine Feder gehaltenen Stange schleift, die durch einen Hebel zur Aufzeichnung des Maschinenhubes quer verschoben wird.The subject of the invention is a micro indicator with a small stroke for high numbers of revolutions, which differs from the known apparatus of its kind in that it is held in a known manner by a spring , Piston of the pressure cylinder connected to the machine cylinder on its upper end carries a plate on which the thick one with a pen provided end of a rod held by a spring grinds through a Lever for recording the machine stroke is moved transversely.
Die Zeichnung stellt in Fig. ι eine schematische Seitenansicht und in Fig. 2 eine obere Ansicht des Indikators dar.The drawing represents a schematic in Fig. Ι Side view and in Fig. 2 a top view of the indicator.
In einem Zylinder a, der mit dem Maschinenzylinder bei b in Verbindung steht, bewegt sich unter dem Drucke des Dampfes, des Gases o. dgl. ein Kolben c, der von der Feder d in bekannter Weise gehalten wird. Der Kolbenschaft ist am Ende tellerförmig gestaltet. Auf diesem Teller e wird das dicke Ende / einer Stange g durch eine Feder h angedrückt. Durch einen am anderen Ende der Stange g angebrachten Hebel i wird die Stange g und damit ihr dickes Ende f quer verschoben (Hubaufzeichnung), während der Kolben c das dicke Ende f hochhebt (Druckaufzeichnung). In der Mitte desselben ist ein spitzer Schreibstift k angebracht, der auf der Glasplatte I schleift. Ist diese Glasplatte fein berußt oder mit einer anderen dünnen Schicht versehen, so zeichnet der Stift k ein kleines, dem Auge kaum sichtbares Diagramm auf. Dieses Diagramm kann dann später in einem optischen Vergrößerungsapparat betrachtet, ausgemessen, nachgezeichnet oder photographiert werden.In a cylinder a, which is connected to the machine cylinder at b , a piston c moves under the pressure of the steam, the gas or the like and is held in a known manner by the spring d. The end of the piston skirt is shaped like a plate. The thick end / a rod g is pressed against this plate e by a spring h. A lever i attached to the other end of the rod g moves the rod g and thus its thick end f transversely (stroke recording), while the piston c lifts the thick end f (pressure recording). In the middle of the same a pointed pen k is attached, which grinds on the glass plate I. If this glass plate is finely sootized or provided with another thin layer, the pen k draws a small diagram that is barely visible to the eye. This diagram can then later be viewed, measured, traced or photographed in an optical enlarger.
