KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei vorliegender Erfindung soll durch eigenartige Anordnung der Spannschrauben und der zugehörigen Muttern neben Herbeiführung einer gleichmäßigeren Anspannung des Trommelfelles ein Verziehen des Kessels verhütet werden.In the present invention, by a peculiar arrangement of the tensioning screws and the associated nuts in addition to bringing about a more even tension of the eardrum warping of the boiler must be prevented.
Bei der bisher gebräuchlichen Anordnung der Spannschrauben trat dadurch leicht ein Verziehen der Kesselwandung ein, dafs der das Muttergewinde tragende, auf derselben angebrachte Wulst (das Widerlager der Schrauben) beim Anziehen der Schrauben die Wand eindrückte infolge des einseitigen Anzuges.With the previously common arrangement of the tensioning screws, this resulted in a slight distortion the boiler wall, that the one bearing the nut thread is attached to it Bead (the abutment of the screws) pressed into the wall when the screws were tightened as a result of the one-sided suit.
Dieser Uebelstand wird nun dadurch beseitigt, dafs für je zwei Spannschrauben, welche auf
je einen der Trommelfellwülste wirken, ein gemeinsames, die beiden Muttergewinde enthaltendes
Widerlager auf der Kesselwandung angeordnet ist. Bei einigermafsen vorsichtigem Anziehen
dieser beiden Schrauben kann dann der Wulst weder nach der einen, noch nach der
anderen
werden.This inconvenience is now eliminated in that a common abutment containing the two nut threads is arranged on the boiler wall for every two tensioning screws which act on one of the eardrum bulges. If these two screws are tightened somewhat carefully, the bead can neither move towards one nor the other
will.
In beiliegender Zeichnung
dargestellt.In the accompanying drawing
shown.
Fig. ι zeigt eine mit der Spannvorrichtung versehene Trommel in Ansicht, theilweise im Schnitt, und Fig. 2 ist ein Grundrifs zu Fig. 1.Fig. Ι shows one with the jig provided drum in view, partly in section, and Fig. 2 is a plan of Fig. 1.
Auf den beiden Trommelfell wulsten α und a1 On the two eardrum bulges α and a 1
Seite in die Wandung hineingedrückt ist die Erfindung liegen die metallenen Ringe r r1, die mit den Lappen \\λ versehen sind. Diese Lappen dienen zur Aufnahme der Köpfe χ der Spannschrauben s bezw. s1. Das Muttergewinde für je zwei einander gegenüberliegende Schrauben s und s1 befindet sich in einem gemeinschaftlichen Widerlager 0, welches auf der Mitte der Kesselwandung B oder nahe derselben befestigt ist.The side of the invention is pressed into the wall, the metal rings r r 1 , which are provided with the lobes \\ λ . These tabs are used to accommodate the heads χ of the clamping screws s respectively. s 1 . The nut thread for two opposing screws s and s 1 is located in a common abutment 0, which is attached to the middle of the boiler wall B or close to it.
Wie ersichtlich, kann nun beim Anziehen einer dieser beiden Schrauben 5 oder s1 des Widerlagers weder nach der einen oder der anderen Seite in die Kesselwandung gedrückt werden, da jede der Schrauben der anderen entgegenwirkt.As can be seen, when one of these two screws 5 or s 1 of the abutment is tightened, it cannot be pressed into the boiler wall either to one side or the other, since each of the screws counteracts the other.
Das Muttergewinde der Schrauben s s1 kann auch statt in den Widerlagern 0 in den Lappen ^ ^1 oder in darauf ruhenden besonderen Muttern enthalten sein, auch können die Köpfe χ unter den Widerlagern 0 liegen.The nut thread of the screws ss 1 can also be contained in the tabs ^ ^ 1 or in special nuts resting on them instead of in the abutments 0; the heads χ can also be under the abutments 0.
