Description

Body for so-called woodwind instruments, flutes, clarinets, oboes and the like have hitherto been made essentially with a wooden body, so that these instruments with the collective name "Hc> Izb'lasinstrument" are designated. You stand out characterized by a beautiful tone characteristic of the wooden body.

The production of such woodwind instruments is very cumbersome and time consuming. The woods used to manufacture the wooden bodies must last for years have stored. Then the bobbing turns out to be very tedious. Around z. B. to achieve a hole in a flute body that does not warp mie: hr, it is necessary to drill out the piece of wood in stages. The time required can take several years to keep the wood as free of tension as possible, while still during processing due to the structural properties of the wood a lot of waste is created by the bursting of the thin walls.

Because of these difficulties, metal ones have already been used To use instrument bodies for flutes, etc. .. No such metal body The body was made of thin-walled seamless sheet metal tubing to make it too heavy manufactured, in which the holes and, their straps pulled out or soldered on became.

These tubular brass instruments have the disadvantage that with them the characteristic tone of a wooden body is lost and a metal sound is created. They also have the disadvantage that the required protective coating only through Silver-plating or nickel-plating can be produced, which makes the instrument more expensive. As a result of the thin-walled material, it is also not possible to store the flaps asw. to screw in the serving ball screws. Special support rails are required for this are provided.

The invention creates for the hitherto customary Holzblasinstru: ments a body which overcomes all of these disadvantages. This is done by choosing one : Material achieved, surprisingly in the training according to the invention the instrument body is reflected in the beauty of sound from a wooden 1) 4as instrument does not differ.

According to the invention, this is achieved because the instrument body consists of light metal, preferably of hyd, ronal, ium and is expediently made of the full drilled cavity is provided with an incorporated grid.

As a result of its desolate low weight. the body can use light metal be made with correspondingly thick walls, so that the ball screws can be screwed in directly to hold the mechanics, which in addition to a material saving also a greater strength is achieved.

One advantage of hydronalium is that it ate by electrolytic Oxidation is possible, the instrument both inside and outside with a protective coating to be provided in any desired color. Through this electrolytic oxidation The coating is so hard that the instrument is particularly light-bubble and beautiful in tone (brilliant in tone) becomes.

Due to the grid worked into the inside of the hole in the body is, as experiments have shown, made possible by a purely metal instrument Generate wood tones Tu. The grid inside the instrument takes place in form a spiral that goes through a carbide steel tip from both sides of the instrument is scratched, with a normal threaded spindle doing the feed. This can be done in the form of single as well as double wavy lines (cross grid).

When the grid only extends over part of the body bore and this part can be disconnected from the rest of the smooth bore, it is possible to use both pure metal and pure wood tones with the same instrument to create.

The production of the metal body according to the invention can be carried out in the shortest possible time Time. It is not necessary to have such long manufacturing times as with wooden bodies To have to accept, where in the raw material and in semi-finished products considerable for years Capital is set.

The drawing shows a view, partly in section, of an exemplary embodiment of the invention with the partial representation of a flute.

The flute body 1, which is preferably made of hydronalium, is with the longitudinal bore 2, in which the usual holes 3 for the flaps etc. flow out. The longitudinal bore 2 is expediently drilled out of the solid material. It but is also possible, the body 1 from a correspondingly thick-walled Manufacture pipe section. Of course, there are all finger holes and Lid on the instrument at the usual. Space so that the musician can only grasp the known Has to perform operations.

The tone holes 3 are drilled and with a support edge 4 for the key padding provided, also milled out, so that part of the flap in the lower diameter the holes 3 engages. To make the instrument as light as possible, you can In the body 1 further millings may be provided, but the beauty of the body not be allowed to affect. The holes 5 for the bearings of the mechanics are directly into the wall de; Body incised.

The inner wall of the bore 2 is with a. Cross grid 6 provided, which consists of two wavy lines running approximately perpendicular to one another, the are pressed into the hydronalium of the body 1 or otherwise incorporated. Of the The Nensilverzug required in the flute mouthpiece is expediently warm in the hydronalium body depressed. Such a new nickel silver slide is necessary to keep the metal head from sliding with as little wear as possible.
