PATENTAMTPATENT OFFICE
Die zur Bewegung der an den Blechblasinstrumenten vorhandenen Cylinderventile dienenden Tasten der Klaviatur werden gegenwärtig durch je eine in einer Trommel befindliche, spiralförmig gewundene Feder (Uhrfeder) in die Ruhelage zurückgebracht. Den mit dieser Federanordnung verbundenen Uebelständen soll durch die in den Fig. 1 und 2 abgebildete Vorrichtung mit den Tastenhebeln αλ α1 begegnet werden. Dieselbe besteht aus der Grundplatte g, in welche die vier Säulchen d eingeschraubt sind. Zwischen den letzteren ist für jeden Tastenhebel αλ α- mittelst der Schrauben e auf der Platte g mit dem einen Ende eine schraubenförmig gewundene, aus dünnem Messingdraht gefertigte Feder b befestigt, deren anderes Ende um die Lagerhülse h des Tastenhebels al a1 gelegt und an einen am letzteren befestigten Schraubenstift c gehakt ist.The keys of the keyboard, which are used to move the cylinder valves on the brass instruments, are currently brought back into the rest position by a spiral-shaped spring (clock spring) located in a drum. The inconveniences associated with this spring arrangement are to be countered by the device shown in FIGS. 1 and 2 with the key levers α λ α 1 . It consists of the base plate g into which the four pillars d are screwed. Between the latter, a helically wound spring b made of thin brass wire is attached to one end of the screws e for each key lever α λ α- on the plate g , the other end of which is placed around the bearing sleeve h of the key lever a l a 1 and is hooked on a screw pin c attached to the latter.
Der Tastenhebel al a1 ist rechtwinklig gebogen; der waagrechte Schenkel α1 bildet die Taste, während der senkrechte Schenkel a1 die Drehung des Ventils veranlafst. Zu diesem Zwecke ist er am unteren Ende mit einer Durchbohrung versehen, mittelst welcher er mit der zur Drehung des Ventils dienenden Stange verbunden wird. Der Scheitel des Tastenhebels a1 a} enthält eine Durchbohrung, in welche die Lagerhülse h eingeschraubt wird, so dafs der Tastenhebel al a1 und die Lagerhülse h ein Stück bilden. Letztere ist mit einem vorspringenden gereifelten Rand versehen, um ein Abfallen der Feder b von der Hülse h zu verhindern.The key lever a l a 1 is bent at right angles; the horizontal leg α 1 forms the key, while the vertical leg a 1 causes the valve to rotate. For this purpose it is provided with a through-hole at the lower end, by means of which it is connected to the rod used to rotate the valve. The apex of the key lever a 1 a} contains a through-hole into which the bearing sleeve h is screwed so that the key lever a 1 a 1 and the bearing sleeve h form one piece. The latter is provided with a protruding, ripened edge to prevent the spring b from falling off the sleeve h.
Die Säulchen d, welche am oberen Ende rechtwinklig umgebogen sind, haben in den waagrechten Schenkeln Durchbohrungen, durch welche die Spindel/, nachdem auf diese vorher der Tastenhebel al a1 mit seiner Lagerhülse h aufgeschoben worden, hindurchfuhrt. Die Säulchen d dienen aufserdem noch dazu, die Tastenhebel a1 a- von einander getrennt zu halten und dadurch eine Behinderung der Hebel al a2 unter einander beim Niederdrücken zu vermeiden. The columns d, which are bent at right angles at the upper end, have through-holes in the horizontal legs through which the spindle /, after the key lever a l a 1 with its bearing sleeve h has been pushed onto it beforehand. The columns d also serve to keep the key levers a 1 a- separated from each other and thereby prevent the levers a 1 a 2 from being interfered with each other when they are pressed down.
Die Spindel f hat am linken Ende ein Gewinde, welches in das in der Durchbohrung des linken Säulchens d vorhandene Muttergewinde eingeschraubt wird und dabei so weit herausragt, dafs eine Gegenmutter auf das linke Ende der Spindel geschraubt werden kann. Die Spindel f liegt demnach unwandelbar in ihren Lagern fest, während die Tastenhebel α1 α- mit den LagerhUlsen /; sich um die Spindel / hin- und herbewegen lassen.The spindle f has a thread at the left end which is screwed into the nut thread present in the through-hole of the left column d and protrudes so far that a lock nut can be screwed onto the left end of the spindle. The spindle f is therefore immutable in its bearings, while the key lever α 1 α- with the bearing sleeves /; can be moved back and forth around the spindle /.
Die Stärke des zu der schraubenförmig gewundenen Feder b verwendeten Drahtes richtet sich nach der Wirkung, welche von der Feder b verlangt wird. Um durch eine Lockerung der Befestigungsschraube e ein Verdrehen der Feder b und dadurch ein Abspannen derselben zu verhindern, ist in die untere Höhlung ein Stellstift eingeschoben, welcher andererseits in die Grundplatte g eingesetzt wird.The strength of the wire used for the helically wound spring b depends on the effect which is required of the spring b. To a loosening of the fastening screw E b twisting of the spring and thereby prevent unclamping thereof, in the lower cavity of an actuating pin is inserted, which is the other part in the base plate g.
Die Gröfse der Vorrichtung und der dazu gehörigen Theile richtet sich nach der Art des Blechblasinstrumentes, an welchem die Vorrichtung angebracht werden soll, wobei zu be-The size of the device and the parts belonging to it depend on the nature of the Brass instrument to which the device is to be attached, whereby
achten ist, dafs jeder Tastenhebel α1 α2 von dem anderen durch ein Säulchen d getrennt bleiben mufs, wie in der Fig. ι dargestellt ist.it is important to ensure that each key lever α 1 α 2 must remain separated from the other by a column d , as shown in FIG.
