Bandsäge mit zwei in horizontaler Richtung schneidenden und vertical verstellbarenBandsaw with two horizontally cutting and vertically adjustable

Sägeblättern.Saw blades.

Patentirt im Deutschen Reiche vom 31. Juli 1878 ab.Patented in the German Empire on July 31, 1878.

An den Seiten von zwei hohlen Ständern, welche unten durch eine Fundamentplatte und oben durch ein Zwischenstück verbunden sind, sind zwei Supportplatten in Prismenführungen vertical verstellbar angebracht. Dieselben tragen je zwei Zapfen, um welche die Sägescheiben rotiren, deren eine mit der Antriebsriemscheibe verbunden ist, während der Zapfen der anderen Scheibe mittelst Schraubenspindel und Wandrad und federnder Zwischenlage in horizontaler Richtung in einer Prismenführung beweglich ist, um dem um die Scheiben gelegten Sägeblatt die nöthige Anspannung ertheilen zu können.On the sides of two hollow uprights, which are supported by a foundation plate and below are connected at the top by an intermediate piece, two support plates are in prism guides vertically adjustable. They each have two pegs, around which the saw disks rotate, one of which is connected to the drive pulley, while the pin of the the other disk by means of a screw spindle and wall wheel and a spring-loaded intermediate layer in a horizontal position Direction is movable in a prismatic guide to the one placed around the panes To be able to impart the necessary tension to the saw blade.

Der Antrieb vom Vorgelege aus kann geschehen mittelst Riemenspanner wie in' Blatt I, mittelst eine* beweglichen Zwischenrolle, welche von zwei mit der Welle des Vorgeleges bezw. mit der Supportplatte drehbar verbundenen Balanciers getragen wird, wie in Blatt Π, oder mittelst irgend einer anderen Vorrichtung, wodurch bei der wechselnden Stellung der Supportplatten eine constante Riemenlänge erzielt wird.The drive from the countershaft can be done by means of a belt tensioner as in 'Sheet I, by means of a * movable intermediate roller, which of two with the shaft of the countershaft respectively. with the support plate rotatably connected balancer is carried, as in sheet Π, or by means of some other device, whereby the changing position of the support plates a constant belt length is achieved.

Zur Verstellung jeder Supportplatte, also jedes Bandsägeblattes in verticalem Sinne dient eine auf den Deckplatten der Ständer gelagerte Welle, welche durch eine Handkurbel oder bei grofsen Anlagen durch Riemenbetrieb gedreht wird und die Bewegung mittelst zwei Paar konischer Rädchen auf zwei verticale Schraubenspindeln überträgt, deren Muttern mit der Supportplatte verbunden sind.For adjusting every support plate, i.e. every band saw blade in a vertical sense serves a shaft mounted on the cover plates of the stand, which is driven by a hand crank or, in the case of large systems, is rotated by belt operation and the movement is medium transfers two pairs of conical wheels to two vertical screw spindles, their nuts are connected to the support plate.

Die beiden Wellen können durch zwei auf denselben verschiebbare und in einanderThe two shafts can be displaced by two on the same and into each other

greifende gleich grofse Stirnrädchen gekuppelt werden, so dafs durch Drehung einer der Wellen beide Supportplatten., also auch beide Sägeblätter um gleichviel gehoben oder gesenkt werden.gripping spur gears of equal size are coupled, so that by turning one of the Both support plates are corrugated, so both saw blades are raised or lowered by the same amount will.

Zwischen den Ständern bewegt sich auf Rädern über Schienen ein Wagen zur Aufnahme der Holzblöcke, welcher durch das kleine, unter dem Hauptvorgelege befindliche Vorgelege mit verschiedenen Geschwindigkeiten vorwärts und rückwärts bewegt werden kann.A carriage for pick-up moves on wheels between the uprights over rails the blocks of wood, which through the small, under the main gear reducer at different speeds can be moved forward and backward.

Diese Bandsäge arbeitet mit zwei Sägeblättern, wodurch ihre Leistungsfähigkeit nach Ansicht des Erfinders die aller anderen Sägen übertrifft, während durch die wegen der horizontalen Stellung der Sägeblätter ermöglichte feste Unterstützung des Wagens mit dem Holzblock durch das Fundament eine so grofse Genauigkeit im Schnitt erzielt wird, dafs die Bandsäge auch als Fourniersäge verwendet werden kann.This band saw works with two saw blades, which in view of its efficiency the inventor outperforms that of all other saws, while due to the horizontal The position of the saw blades enabled the carriage to be firmly supported with the block of wood the foundation achieves such a precision in the cut that the band saw does can also be used as a fournier saw.
