DE102019007086B3 - Circular wiper for baritone saxophones - Google Patents

Abstract

Circular wipers for baritone saxophones, soprano, alto and tenor saxophones are dried and cleaned with a swipe after playing. With the baritone saxophone, this method is difficult because of the loop-shaped design of the main pipe end and the high weight. That is why almost all musicians use the water drainage flap built into the loop and leave a large part of the moisture in the instrument. This is unsanitary and over time results in deposits that change the sound of the instrument. With the rotary wiper, the first step is to run a thin string through the body. A weight is used for this. Then the wiper is integrated. Small carabiners and rings are used to connect the weight, cord and wiper. This creates a closed circle, with the circle running through the body of a baritone saxophone, which allows the instrument to be wiped as often as required and thus completely removes moisture.

Description

The saxophone family consists essentially of four different types - Soprano saxophone (ss) Alto saxophone (as) Tenor saxophone (ts) Baritone saxophone (bs)

When these instruments are played, warm, moist air flows through the mouthpiece into the instrument.

Since this is made of metal, the moisture is deposited as condensation, which should be removed after playing. If this does not happen, deposits will form, which will change the sound of the instrument.

The removal of this moisture is done for the saxophones (ss), (as) and (ts) with standard wipers.

A weight connected to the wiper (usually a microfiber cloth is passed through the bell and the main pipe and pulled through. The S-bend attached to the main pipe is cleaned separately with another wiper.

The instrument is now dried by wiping it through several times with the wipers.

With the baritone saxophone (bs), however, there is a problem:

Between the S-bend and the main pipe there is a strongly curved and loop-shaped intermediate piece, which is composed of two U-shaped pipes. If the (bs) is played, the condensation water is almost completely reflected in the loop. A water drainage flap is installed at the lowest point of the loop, but with the help of which the condensation water can only partially be removed.

This gradually causes deposits to form, which impair the sound and playability.

State of the art for removing residual moisture:

Most of the time, a pull-through wiper for the (as) is adapted to the (bs), whereby the cord is lengthened accordingly and the weight is juggled through the bell, main pipe and adapter.

This explains a link to a YouTube video that demonstrates this method. https://www.youtube.com/watch?v=IFmMv_p9Z9k

The Thomann company - Germany's largest music retailer - sells such a wiper, manufactured by Gewa Music.

  • Use is demonstrated at https://www.youtube.com/watch?v=8PH_QPml0Zk.

However, deficiencies are evident. The unwieldy swiping of the wiper is clearly recognizable. The weight of the baritone saxophone - approx. 6 kg - plays a role. Since wiping is only optimal if it is done several times, it is not surprising that almost all of them Musicians do not use this method. You reduce the cleaning process to pressing the water drainage flap.

In the event of an overhaul of the instrument, the intermediate piece can be removed and cleaned, but this is a time-consuming and expensive process, since the flaps and stabilizing struts also have to be removed.

In the GB 2482327 A , see in particular pages 1 to 3 of the figures, a tenor saxophone is shown. In the US 1730785 A , see in particular 1 , becomes an alto or tenor saxophone body shown. The wipers in these two documents are intended to cover the entire inner surface. Such wipers are manufactured, for example, by BG and Kölbl. However, such wicher are only offered for alto or tenor saxophones. In the US 3739420 A , see in particular the 1 to 6th , a new material (polyurethane) is used for the conical inner part of the wiper. In the JP 2017-111391 A , see in particular the 1 to 4th and the abstract, the main application is the removal of stains in a curved pipe.

In summary, it can be said that none of the wipers takes into account the problem of the special body shape of the baritone saxophone.

In addition, the wiper must be passed through the saxophone body again with each wiping process.

Thus, the task arises of inventing a method that enables the baritone saxophone (bs) to be wiped several times with little effort and that is just as thoroughly cleaned as the saxophones (ss), (as) and (ts).

The basic idea is to create a closed circle out of a cord and a wiper.

The prototype uses the following parts. 1. A thin string of eight feet (Kite building) 2. 2 mini carabiners, 2 snap rings (Craft supplies) 3. Drop-shaped weight (30g) with eyelet (Fishing supplies) 4. Commercially available swiping wiper (as).

• Die Schnur des Wischers wird auf 50cm verkürzt und das Gewicht am Ende der Schnur entfernt.
• Die Seite des Wischers,der an der Korpuswand wischt sei nun die Außenseite des Wischers. An der Innenseite des Wischers wird ein Sprengring (WR) angenäht, möglichst nahe am Zentrum des Wischers .

A mini carabiner is attached to each end of the cord and the pull-through wiper is modified as follows:

• The cord of the wiper is shortened to 50cm and the weight at the end of the cord is removed.
• The side of the wiper that wipes the body wall is now the outside of the wiper. A snap ring (WR) is sewn onto the inside of the wiper, as close as possible to the center of the wiper.

The other snap ring is attached to the end of the cord (SR).

And this is how the wiping process takes place:

At the end of the kite line, the weight is attached to the carabiner, which is passed through the (bs) from the loop side. The thin cord is pulled through the (bs) by the weight. If it emerges at the end of the bell, it is removed and the ring (SR) is hooked into place. The other end of the cord still protrudes from the loop. The wiper ring (WS) is now hooked in here. A self-contained wiper circle is now formed and it can be wiped through as often as desired.

The (as) wiper is first pulled through on the thin cord with little force and the (as) wiper residual cord appears on the loop side of the (bs) body. The wiper can now be pulled through the loop with greater force on this remaining cord.

The advantages of this cleaning technique are obvious.

If the closed circle of wiper and cord has been created, the (bs) can be put down or placed in a stand and you have both hands free to pull it through. With the saxophones (ss), (as) and (ts) you always have to keep the instrument in your hand if you wipe it several times.

With a new instrument (bs) the original sound will be retained,
a used one will restore the original sound over time.

Final remark:

Baritone saxophones have been made since 1850. Nobody had the idea to build a rotating wiper.
After applying for a patent, it is planned to contact the Thomann company.
Since the rotary wiper is the GEWA wiper - sold by Thomann -
is far superior, cooperation is to be expected. Together with the wiper manufacturers GEWA or Kölbl, a market-ready version could then be developed.
Then you can think of the big saxophone producers
(Yamaha, Yanagisawa, Selmer, ...) to convince their baritone saxophones with a rotary wiper. So far, the instruments have been sold without a wiper.
