Description
PΛΪ E NT ANSPRUCH:PΛΪ E NT CLAIM:
Schabloniervorrichtung zum Herstellen von elliptischen und hypozykloiden Formen, bei der sich an einem feststehenden Zahnrad ein Zahnrad vom halben, drittel, viertel usw. Durchmesser abrollt, dadurch gekennzeichnet, daß der das Schablonenholz tragende Schieber (r) in einer Führung des schwenkbaren; auf einer senkrecht verstellbaren Büchse (c) angeordneten Armes (e) gleitet und von einer Stange in) gesteuert wird, deren Angriffspunkt am Schieber (r) sich durch Verstellen des in einem Schlitz (/) des Zahnrades (g) geführten Exzenterbolzens (I) ändern läßt..Stenciling device for producing elliptical and hypocycloid shapes, in which a gear wheel of half, third, quarter, etc. diameter rolls on a stationary gear wheel, characterized in that the slide (r) carrying the stencil wood in a guide of the pivotable; slides on a vertically adjustable sleeve (c) arranged arm (e) and is controlled by a rod in) whose point of application on the slide (r) can be adjusted by adjusting the eccentric bolt (I) guided in a slot (/) of the gearwheel (g) can change ..

Die Fußplatte a, in welcher die Spindel b sitzt, wird im Sandboden festgerammt, die Büchse c ist mittels der Stellschraube d auf der Spindel b senkrecht verstellbar angebracht. Der Schablonierarm e ist drehbar und das große Zahnrad f festsitzend auf Büchse c angeordnet. Das kleine auswechselbare Zahnrad g, dessen Zähnezahl im Verhältnis zur Zähnezahl des großen Zahnrades / sich verhält wie 1: 2, ist mittels Bolzen h am Schablonierarm e drehbar angebracht. Auf Zahnrad g ist eine Führungsleiste i mit eingehobeltem Schlitz j mittels Schrauben k befestigt. Im Schlitz / ist ein verstellbarer Exzenterbolzen I zum Erzeugen der Exzentrizität eingeschoben; dieser wird durch die Flügelschraube m festgestellt. Die in ihrer Länge verstellbare Steuerstange n, welche einerseits auf Büchse 0, die auf Bolzen I sitzt, und andererseits auf Büchse p drehbar gelagert ist, bewegt mittels Bolzen q den seitlich verstellbaren Schieber/* auf dem Schablonierarm e hin. und her. Auf dem Schieber r, der in prismatischer Führung auf dem Arme e läuft, wird mittels Schrauben, s das Schablonenholz befestiget. Wird nun der Arm e mittels Hand im Kreise gedreht, so bewegt sich das kleine Zahnrad g um das feststehende große Zahnrad f herum; dadurch tritt der Exzenterbolzen I in Tätigkeit und erzeugt mit Hilfe des Schiebers r, der zwangläufig mit dem Arm e läuft, die Ellipsenform,, Durch Verstellen des Exzenterbolzens / und der Steuerstange η erhält man verschiedene Eliipsenformen. Fig. Ι the elevation of the apparatus, Fig. 2 the floor plan of the apparatus, Fig. 3 the section ZZ,
Fig. 4 the section XX.
The base plate a, in which the spindle b sits, is rammed into the sandy soil, the sleeve c is attached vertically adjustable by means of the adjusting screw d on the spindle b. The stencil arm e is rotatable and the large gear f is arranged firmly on the sleeve c . The small, exchangeable gear wheel g, the number of teeth of which in relation to the number of teeth of the large gear wheel / is 1: 2, is rotatably attached to the stencil arm e by means of bolts h. A guide bar i with a planed slot j is attached to gear wheel g by means of screws k. In the slot / an adjustable eccentric bolt I is inserted to generate the eccentricity; this is determined by the wing screw m . The length-adjustable control rod n, which is rotatably mounted on the one hand on bush 0, which sits on bolt I , and on the other hand on bush p , moves the laterally adjustable slide / * on the stencil arm e by means of bolts q . and here. The template wood is attached to the slide r, which runs in a prismatic guide on the arm e , by means of screws, s. If the arm e is now rotated in a circle by hand, the small gear wheel g moves around the stationary large gear wheel f ; This causes the eccentric bolt I to act and, with the aid of the slide r, which inevitably runs with the arm e , creates the elliptical shape. By adjusting the eccentric bolt / and the control rod η , various ellipses are obtained.
