Abstract

Two-tone pipe with an elongated pipe body (1) having a plug (2) for adjusting the pitch in the upper area, characterized in that in the plug (2) has a bore (3) in the longitudinal direction of the pipe body (1) is introduced can be closed or opened by means of a closure acting on the upper edge of the hole with a downstream mechanism, which is in operative connection with the mechanics of the organ instrument.

Description

field of use

The invention relates to an organ pipe, which is equipped with technical means for reproducing two tones of different pitch.

State of the art

To DE 279 08 862 is a covered wooden pipe for alternately generating two tones of different pitch known, which is essentially characterized by a fork in the upper part of the pipe, whereby two pipe ends are formed. By means of a flap one end of the pipe for the air flow can be released, while the other end is closed.

In the pipe ends spits are used to vote the desired pitch.

At a Mehrtonorgelpfeife after DE 10 2007 022 499 the pipe body has an opening which can be optionally closed or exposed via an activatable valve device in order to produce different sounds via the sound space change thus realized. The opening may optionally be located on the lower side of the labium and / or on the opposite upper end of the pipe body. In the latter variant, a lid member including the valve means is slidably disposed in the pipe body for tuning at the upper end.

The identified prior art thus contains advantageous technical solutions, which, however, are not sufficient to meet the object of the invention, namely to provide a two-tone whistle, which can be produced economically with commonly available technical means and knowledge as well as with little equipment.

task

It is therefore an object of the present invention to provide a two-tone whistle pipe based on a wooden pipe with an elongated pipe body having a plug for adjusting the pitch at the top. In particular, technical means for generating a second sound are to be presented.

Solution of the task

The solution of the task is in the protection claim 1 specified. The subordinate claims contain expedient embodiments. The upper opening of a wooden pipe of conventional design for an organ instrument is closed with a felted and / or leather-coated stopper. The plug is arranged longitudinally displaceable in the pipe body for a single adjustment or readjustment of the pitch.

According to the invention, a bore is introduced into the plug in the longitudinal direction of the pipe body. The bore can be closed or opened from above by means of a valve device with associated mechanism. Thus, the pitch is influenced not only by the length of the pipe and the positioning of the plug, but also significantly by the diameter of the bore in the plug. The larger the bore diameter is chosen, the longer the sound waves and the lower the sound produced.

When the valve is closed, a second lower tone can be achieved.

Advantageous embodiments are seen in that a conical closure is used as a closure element, which sits on the upper edge of the bore sufficiently sealingly or can be lifted from this. The cone lock is connected via an eyelet with a rigid rod. This in turn is movably mounted in a lever or other kind of mechanics and is in operative connection with the mechanics of the organ instrument.

embodiment

In one embodiment, the invention will be explained in more detail below with reference to two Prinzipskzizen.

2 shows a wooden pipe of conventional design for an organ instrument with a stopper 2 , in the invention, a bore 3 in the longitudinal direction of the pipe body 1 is introduced.

1 contains the representation according to 2 , plus further essential and expedient features of the valve device with associated mechanism, consisting of the individual parts cone lock 4 , Eyelet 5 , rigid rod 6 and lever mechanism with joint 7 , Seesaw 8th and mobile storage 9 of the staff 6 in the seesaw 8th , The seesaw 8th is in the usual way by the mechanics of the organ instrument movable. It is also conceivable that the organ mechanics directly on the staff 6 or on the cone lock 4 attacks.

The cone lock 4 sits by its own weight sufficiently sealing on the upper edge of the hole 3 on.
