Description
Trommel. Gegenstand der Erfindung ist eine Trommel, welche sich von den bisher im Gebrauch befindlichen Trommeln durch eine -neue Anordnung unterscheidet, die es gestattet, die Trommel schnell auf jede gewünschte Tonart einzustimmen.Drum. The invention is a drum, which is from differentiates the drums previously in use by a -new arrangement, which allows you to tune the drum quickly to any key you want.
Man hat bereits vorgeschlagen, die Trommel durch Betätigen eines einzigen Organs an. Stelle der sechs Stellschlüssel zu stimmen. Von diesen bekannten Vorrichtungen unterscheidet sich der Gegenstand, der Erfindung durch seinen konstruktiven Ausbau, der ein schnelleres Stimmen als bisher ermöglichen soll.It has already been proposed to operate the drum by operating a single Organ. Place the six adjusting keys to vote. From these known devices the subject matter of the invention differs through its constructive development, which should enable faster tuning than before.
In der Zeichnung ist die neue Trommel veranschaulicht, und zwar ist Abb. i eine Draufsicht, Abb.2 eine Seitenansicht, Abb. 3 ein wagerechter Schnitt von Abb. i und -Abb. q. ein senkrechter Schnitt von Abb. 2. Ein Messingreifen i, .der mit verstärkten Rändern 2 versehen ist, bildet den Körper der Trommel. Die Trommelfelle 3 sind über Holzreifen q. gewickelt und über die Ränder des Reifens i mittels zweier Ringe aus Messing 5 gespannt, die durch kleine Klammern aus Aluminium 6 in ihrer Lage festgehalten werden. Die Klammern sind an .dem Ring i der Trommel mittels Schrauben 7 befestigt. An den den Schrauben 7 entsprechenden Teilen des Trommelringes i ist dieser an der Innenseite verstärkt. Im Innern der Trommel befinden sich zwei radartige Gestelle 8 aus Aluminium und Bronze, die mit Speichen 9 versehen sind, welch letztere sich auf einem mit Muttergewinde versehenem Schraubring io vereinigen. Die beiden radartigen Gestelle 8 sind auf einem nach beiden Seiten sich ausdehnenden Zapfen i i aufgeschraubt. Der Zapfen hat an dem einen Ende Rechts-, an dem anderen Linksgewinde und wird mittels eines runden mit schrägen Zähnen ausgestatteten Mittelstücks 12 gedreht, welches von außen her durch eine Stange 13 in Drehung versetzt wird. Die Stange 13 führt nach innen in eine nach drei Richtungen wirkende Schraube ohne Ende 1q.. Diese steht mit den Zähnen des Mittelstücks 12 in Eingriff. Die Stange 13 wird von außen durch den Schlüssel 15 betätigt. Die Trommel wird in folgender Weise gestimmt. Zunächst dreht man den Schlüssel 15 nach der gewünschten Richtung. Der nach zwei Richtungen geführte Zapfen i i tritt darauf mehr oder weniger in die Schraubenmuttern io der radartigen Gestelle 8 ein und zieht diese letzteren j e nach der ange-4vendeten Drehrichtung entweder nach der Mitte, d. h. zueinander hin oder voneinander fort, wodurch der Druck auf die Trommelfelle entweder verstärkt oder vermindert und ein mehr oder minder tiefer Ton erzielt wird. Die Spannung der Trommelfelle wird auf diese Weise in kurzer Zeit mit völliger Gleichmäßigkeit erreicht.In the drawing the new drum is illustrated, namely is Fig. I is a plan view, Fig. 2 is a side view, Fig. 3 is a horizontal section from fig. i and fig. q. a vertical section of Fig. 2. A brass hoop i, . Which is provided with reinforced edges 2, forms the body of the drum. the Eardrums 3 are over wooden hoops q. wrapped and over the edges of the tire i clamped by means of two rings made of brass 5, which are secured by small brackets made of aluminum 6 are held in their position. The brackets are on the ring of the drum fastened by means of screws 7. On the parts of the corresponding to the screws 7 Drum ring i this is reinforced on the inside. Located inside the drum two wheel-like frames 8 made of aluminum and bronze, which are provided with 9 spokes are, which the latter is on a screw ring provided with a nut thread io unite. The two wheel-like frames 8 are on one side on both sides expanding pin i i screwed on. The pin has right-hand, on the other left-hand thread and is equipped with angled teeth by means of a round one Center piece 12 rotated, which is rotated from the outside by a rod 13 in rotation will. The rod 13 leads inwards in a screw acting in three directions without end 1q. This is in engagement with the teeth of the middle piece 12. The pole 13 is operated from the outside by the key 15. The drum is in the following Wisely tuned. First you turn the key 15 in the desired direction. The pin i i, which is guided in two directions, then more or less enters the Screw nuts io of the wheel-like frames 8 and pulls these latter j e according to the direction of rotation used, either towards the center, d. H. towards each other or away from each other, whereby the pressure on the eardrums either increases or diminished and a more or less deep tone is achieved. The tension of the In this way, eardrums are reached in a short time with complete uniformity.
