KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es ist bekannt, dafs man Siebtücher bisher in der Weise festlegte, dafs man — dies ist das älteste Verfahren — das Siebtuch über den unteren Rand des Siebobertheiles legte und mittelst des über den letzteren gezwängten Siebuntertheiles anklemmte. Ein solches Vorgehen veranlafste indessen wegen der unvermeidlichen Faltenbildung bald ein Unbrauchbarwerden des Siebtuches. Diesen Uebelstand sucht die in der neueren Zeit bekannt gewordene Siebtuchbefestigung zu beseitigen, indem das Siebtuch mit seinem Rande an einen Rahmen angeschlossen wird. Dieser Rahmen wird alsdann im Siebmantel befestigt. Die vorliegende Einrichtung strebt nun an, auch bei dem des bequemen Auswechselns wegen in einem Rahmen eingesetzten Siebtuche eine Nachspannung zu bewirken, und erreicht dies, wie mit Bezugnahme auf die beiliegende, einen theilweisen Axialschnitt eines Siebes darstellende Zeichnung des Näheren beschrieben werden soll.It is known that sieve cloths have hitherto been fixed in such a way that one is - this the oldest method - put the sieve cloth over the lower edge of the upper part of the sieve and clamped by means of the lower part of the sieve forced over the latter. Such an approach soon caused the to become unusable because of the inevitable formation of wrinkles Siebtuches. The sieve cloth fortification, which has become known in recent times, seeks this problem to be eliminated by connecting the screen cloth with its edge to a frame will. This frame is then attached to the sieve casing. The present establishment is now striving to re-tension the screen cloth used in a frame because it is easy to change effect, and achieves this, as with reference to the enclosed one, in part Axial section of a screen representing drawing is to be described in detail.
Der Rahmen a, an welchem das Siebtuch b mit seinem Rande befestigt ist, wird durch ein Widerlager c1 des unteren Siebmantels c an einer Abwärtsbewegung gehindert. Etwas weiter nach innen zu liegt das Siebtuch b auf einem zweiten Widerlager c2 des unteren Siebmanteltheiles c auf, welches mit demjenigen cl in ganz oder nahezu gleicher Höhe liegt. Der zwischen diesen beiden Widerlagern c1 c2 befindliche Theil des Siebtuches b wird nun von dem unteren Rande des oberen Siebmanteltheiles d abwärts gedrängt, so dafs ein Straffziehen des Siebtuches stattfindet.The frame a, to which the screen cloth b is attached with its edge, is prevented from moving downwards by an abutment c 1 of the lower screen jacket c. A little further inwards, the sieve cloth b rests on a second abutment c 2 of the lower sieve jacket part c , which lies at the same height as that c l. The part of the sieve cloth b located between these two abutments c 1 c 2 is now pushed downwards by the lower edge of the upper part of the sieve jacket d , so that the sieve cloth is pulled taut.
Bei vorliegender Ausführung wird die axiale Bewegung beider Siebrahmentheile c d gegen einander in ähnlicher Weise bewirkt, wie bei Militairtrommeln. Man kann aber die Spannschrauben e auch durch irgend eine andere geeignete Vorrichtung ersetzen.In the present embodiment, the axial movement of the two screen frame parts cd against each other is effected in a similar way as with military drums. But you can also replace the clamping screws e by any other suitable device.
Da bei einer solchen Anordnung das Siebtuch am inneren Widerlager anliegt, kann man auch den in der Zeichnung unteren Theil des Siebrandes nach oben kehren oder, mit anderen Worten, man kann die Widerlager c1 und c2, anstatt am unteren, am oberen Siebmanteltheil anbringen.Since with such an arrangement the sieve cloth rests against the inner abutment, the lower part of the sieve edge in the drawing can also be turned upwards or, in other words, the abutments c 1 and c 2 can be attached to the upper part of the sieve jacket instead of the lower part .
