PATENTAMT.PATENT OFFICE.
Die Trommeln werden bekanntlich bisher in der Weise gespannt, dafs man von aufsen über die Trommelfelle gesteckte Ringe mittelst Schrauben oder Schnüre gegen einander zieht.As is well known, the drums have hitherto been tensed in such a way that one looks from the outside The rings put over the eardrums are pulled against each other by means of screws or cords.
Diese Spannvorrichtungen sind, weil aufsen angebracht, oft störend und das Spannen selbst erfordert viel Zeit.These clamping devices, because they are attached externally, are often bothersome and the clamping itself takes a lot of time.
Alle diese Manger sind bei der nachstehend beschriebenen, in das Innere der Trommel verlegten Spannvorrichtung vermieden.All of these managers are at the below described, laid in the interior of the drum clamping device avoided.
Fig. ι zeigt eine mit der Spannvorrichtung versehene Trommel im Verticalschnitt.Fig. Ι shows a drum provided with the clamping device in vertical section.
Fig. 2 zeigt dieselbe im Horizontalschnitt.Fig. 2 shows the same in horizontal section.
In die Blechtrommel α sind nach aufsen Wulste (Z1 a2 "durchgedrückt, in welche die mit den Trommelfellen b1 b2 verbundenen Reifen C1 C2 eingelegt werden. Zwischen den Trommelfellen liegen zwei gezahnte Bandreifen oder Blechringe dx d2 , die mit den gezahnten Theilen auf einander sich verdrehen lassen.Are α in the sheet metal drum according aufsen beads (Z 1 a 2 by pressing ", in which the b with the eardrums 1 b 2 associated tire C 1 C 2 are inserted. Between the eardrums are two toothed belt tires or sheet metal rings d x d 2, can be twisted with the toothed parts on each other.

Rings d 2 fastened angle e 2 mounted adjusting screw presses f , which protrudes with its head outward from the drum (Fig. 2).
Durch Drehen der Schraube werden die Ringe af, d.2 gegen einander verschoben, und da hierbei die Zähne der Ringe auf einander aufsteigen (Fig. 1), werden die Trommelfelle b1 b2 gespannt. Zum Spannen der über das eine Fell b.2 liegenden Darmsaite g dient die mit Haken versehene Schraube h, welche durch die Flügelmutter i angezogen werden kann.By turning the screw, the rings are af, d. 2 shifted against each other, and since here the teeth of the rings rise on each other (Fig. 1), the eardrums b 1 b 2 are tensioned. For tensioning the one skin b. 2 lying gut string g is provided with a hook screw h, which can be tightened by the wing nut i.
Der Ring d2 ist mit der Trommel α durch Niete η derart verbunden, dafs er sich nicht drehen, aber auf und ab verschieben kann.The ring d 2 is connected to the drum α by rivets η in such a way that it cannot rotate but can move up and down.
Die Schraube f kann auch mit vierkantigen Zapfen versehen werden, um einen Schlüssel aufstecken zu können.The screw f can also be provided with a square pin so that a key can be attached.
