CLASS 51: Musical instruments.

To the value and essence of the subject matter of the present invention forming keyboard instruments easier to grasp, should be said in advance that with the previous Harmonies when several registers at different pitches, e.g. 16 ', 8' and 4 ' are drawn, while playing the individual notes in the middle of the chords are doubled and triple, depending on the number of registers pulled, on the other hand the lower bass tones, as well as the upper discant tones remain isolated, which gives the piece of sound its clarity loses, if not also becomes incomprehensible.

The present instrument is intended to remedy this great disadvantage by adjusting the pitch 16 ', 8' and 4 'not by special rows of tongues, but solely by the mechanism which is activated by levers under the keyboard can be.

You only need one row of tongues for three rows of tongues (registers); 8 'is through the upper key position perpendicular to the instrument, 4 'through the second one below Key lever row diagonally after the upper octave, 16 'through the third diagonally below played after the lower octave key lever row (see Fig. 9).

Each row of reeds can therefore be played in any three different pitches.

If all registers are now 16 'when playing, 8 'and 4' drawn, which is to be done with the new instruments through the three manual registers has, then the piece of music in question sounds with clear errors without a specified error Accords, since each tone is only present once and doubles in the wrong place are not can address. The same applies if two or more rows of tongues (registers) be brought under the new three-part keyboard and mechanics. Always will result in a similar music.

The following sound images give a precise overview, as is often the case with the previous harmonium the individual tones, e.g. B. Repeat the C major chord through registers 16 ', 8' and 4 '. According to this pattern one can make sound pictures of every figure in a piece of music, and one will find that as soon as the root does not match the upper melody tone, the melody by the Overweight of the secondary tones in the middle register is suppressed. See the following example for the well-known harmonium:

It should be noted that one or two more games are appropriate in the discant, or one or two more in the bass half registers are left out so that the discant can stand out particularly. Want if you win a 2 ', a row of tongues must be placed an octave higher.

Through the construction of the new instrument, as the above tone pictures show, the aim of correct playing and better and full utilization of the tongue material, furthermore, the instrument should give the player in such a way that the toggle lever (left) gives him all the stops individually and in any composition or order, without the Having to interrupt the game.

The keyboard consists of three superposed parts abc (Fig. 1), which are connected by a movable member (Fig. 8). The upper part alone is provided with buttons. The two lower levers b and c are always moved when the keyboard is played. While α is now perpendicular to the instrument, the levers b are placed at an angle to the upper octave and the levers c at an angle to the lower octave.

The construction of the connecting member ρ (Fig. 8) of the keyboard α with the levers b and c should exclude any friction on the keys, making the variety very pleasant and easy to regulate.

The mechanism (Fig. 1), which is attached behind the keyboard, has a playing bar e, in which three levers d are attached one above the other in such a way that they rest on the three corresponding levers abc . If one of the three keyboards is now to come into operation, only the rear end of the relevant lever d may be lifted or held, the playing rod e is then raised when a key is pressed and opens the reed valve. Each of the three levers abc lying one above the other can be set into action individually with the mechanics, even half in the Bafs or Discant; furthermore, part of the lower lever c is to be used as a subbafs. Each reed register or manual register (ie levers lying one above the other) can be pulled to play as usual. However, each individual register must also be connected to the left toggle lever by gently pressing the sheet metal angle lever h (Fig. 5).

The left knee lever moves a bar ο (Fig. I, 4, 5 and 6) up and down under all register pulls. If the register pull rod is now removed a little by the angle lever k (FIG. 5), a hanger f (FIG. 5) falls onto the toggle bar 0 and the relevant register can then be opened by pressing the toggle lever.

The hangers f (Figs. 4, 5 and 6) are of different lengths, so that the tongue stops can be activated in two spaces one after the other and the manual stops only come into effect in the third space when the left knee lever is pushed back completely.

This facility now allows you to play any three games with the knee lever in advance place. The smallest selected game is drawn in full (Fig. 4), which means that you can now use the three games set in the knee lever, four games without further registration during the Game available. The right knee lever is only to be used for the forte.

The opening of the register flaps m in the wind chest is sufficiently evident from FIG. 2 of the drawing; It is only to be noted here that with the old harmonies a great expenditure of force is necessary for this, and a great deal of wind is lost. The new register flaps, however, are not under spring pressure and

open very easily. Loss of wind cannot occur because the flap lifting rods r go through a stuffing box \ , which the latter closes very tightly and is easy to re-seal.

The fan (Fig. I) has to supply 12 games in the discant and 9 games in the ßafs Wiud. In order to make this possible, two closely spaced scoop bellows Wm are provided over the entire width of the instrument, namely in an upright position so that> no force can be lost to lift the bellows themselves. The middle board s between the two bellows is moved back and forth by the player through the two running boards. The tension strap goes from the running boards at the back of the instrument over a pulley if, so that with every single step one of the double bellows alternately sucks and the other presses the wind into the collecting bellows. The collecting bellows is located on one wall i of the scooping bellows. The other outer wall of the scooping bellows is free-floating and must be held by an elastic support u , since this outer bellows wall moves up and down a little when the partition s moves. The transfer of the wind from this outer scooping bellows to the collecting bellows is done by an elastic Windkannl v. The pumping bellows close to the collecting bellows gives the pressure wind directly through the wall z; on the other hand, the wind is supplied through a channel χ between the scoop and collecting bellows.

The wind is now from the collecting bellows on both sides of the instrument after the Wind chamber, which is located in the upper part of the instrument and with to complete a soundboard. From here the wind goes down through the tongues after the sound room, which is closed by the forte flap.

Only color shades have been chosen for the designation of the tongue registers. The manual register indicate the pitch 16 ', 8', 4 ', 2' in the relevant colors.

It is particularly noted that the above explanations relate first of all to the drawing which illustrates the invention on a harmonium. However, it should Essential of this invention, the better utilization of the clay material, mainly with smaller and larger church organs can be used. According to the Inventor, the invention is to be used mainly wherever there is room for large Works not available or where the means to carry out larger works are limited in that almost a triple tone effect can be achieved at a low cost by the application of the above invention can.

Claims (4)

Patent Claims: 1.
