ANDREAS RADOVANOVIC, OF ZURICH, SWITZERLAND.

REED-ORGAN.

Specification of Letters Patent.

Patented Aug. 13,1912.

Application filed March 21, 1911. Serial No. 615,889.

To all whom it may concern Be it known that I, ANDREAS RADOVANO- vie, a citizen of the Republic of Switzerland, residing at Zurich, Switzerland, have invented new and useful Improvements in IteedOrgans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in musical instruments having reeds of which reed organs are a. type and its object is to obtain a modulation of the sound in such instruments. This is effected by inserting throttling devices between the valves of the reeds and those of the stop which by throttling the wind passing through the reed modulate the sound. When the sound of single reed is to be modulated the throttling device is operated from the key of that reed; when the sound of all reeds played at the same time is to be modulated, from a rail operated by a pressure of the knee or a hook lever.

Reference is to be had to the accompanying drawings in which like parts are similarly designated.

Figures 1 to 3 illustrate the invention in connection with a harmonium operated by suction and Figs. 4 to 6 illustrate a harmonium operated by pressure. Fig. 1 is a vertical section through the upper part of a harmonium operated by suction, Fig. 2 is partly a section on line IIIIV of Fig. 1 and partly a plan view of part of the harmonium. Fig. 3 is a section on line I-II of Fig. 1. Fig. 1 is a view of a rail by which the sounds of several reeds may be modulated, seen as indicated by arrow y in Fig. 1. Fig. 5 is a vertical section of a harmonium operated by pressure. Fig. 6 is a plan view of part of Fig. 5. Fig. 7 is a section on line V-VI of Fig. 5.

Those parts of the harmonium which are not directly related to this invention have been omitted.

t designates a key, the stroke of which is transmitted to the reed valve 76 by means of a pin 9 in Fig. 1, and a lever l in Fig. 4. Springs 70 tend to keep the valves is closed.

a is a reed tongue.

r is the mute common valves is.

to all the reed a; is a port leading from the mute r to the reed valve 70.

w is the wind chest in which pressure or suction is brought about by means not shown.

The parts above described are known in harmoniums, but the parts now to be described are new and for the subject matter of the present invention. Every pipe 2 has a throttle valve 8 with slots 3 The throttle valve may have any desired number of slots 8 In the suction harmonium (Figs. 1 to 3) the slides are between tongue 2 and valve is, while in the pressure harmonium (Figs. 1 to 6) they are between tongue 2 and mute r. In their idle position shown the slides 8 allow only narrow passages to the air through which only air enough can pass to produce the softest sound of the reed. Then the slide is moved to the right in Figs. 1 and 5 the area of the openings is increased and a louder sound is produced, the intensity of which depends on the area laid open. Under every key there is a bell crank 71. h which transmits the depression of the key 5 to slide 8. This bell crank has a head m which may be so adjusted that in the position of the parts shown there is some play between the head at and the key. A spring f tends to draw the slide 8 and the lower end of bell crank h, h toward an adjustable check a carried by a transverse rail 79. This rail is pivoted at p and extends over the entire key-board. When the rail 7) is turned on its pivots in the sense of the arrow (Figs. 1 and 5) it moves all the slides s to the right and increases the area of the air opening of all the reeds. An arm 22 serves to turn rail 1) which arm may be operated from a knee or foot lever as is well known. A check 6 serves to limit the stroke of the rail 79 toward the left.

The operation of the apparatus is the same for suctionand pressure-organs and is as follows: The keys are depressed so far that they touch the heads m. This causes valves is to open, and the softest sound of the reed is produced. In order to modulate the sound of one reed, z'. e. to more or less intensify it, the key of the pipe is further depressed which causes slide 8 to be displaced to the right and a greater area to be laid open for the passage of the air so that the sound of the reed is intensified accordingly.

When playing a harmony it is possible to render one note more prominent than the others. When the sounds of all the reeds the keys of Which have been depressed until they touch part-s m are to be intensified, rail 7/ is turned in the sense of the arrow and thereby moves all the slides to the right. As the reeds require less air on the treble side, the axis on Which rail 21? swings is so arranged that it is at an angle to a line drawn through all the checks a so that the distance of said checks from the axis 72 of the rail decreases toward the treble which causes the motion of slides s on that side also to de crease. The variation of the openings for the air to pass through may be effected by any suitable throttling device, and the transmission of the key pressure to the tl'irottling device may be effected in any suitable manner. The same throttling device may be used for several reeds played from the same key.

Claims:

1. A reed organ having ports for supplying air to the reeds, and means for varying the sectional area of each of said ports independently.

2. A reed organ having ports for supplying air to the reeds, and slides for varying the sectional area of each of said ports independently.

3. A reed organ having ports for supplying air to the reeds, slides for varying the sectional area of each of the said ports independently, and means connecting the slides to the organ keys.

4-. reed organ having ports for supplying air to the reeds, slides for varying the sectional area of said ports, and a bell crank, for each slide, having an arm engaging the slide and adapted to be displaced by a key.

5. A reed organ having ports for supplyslides for varying the ports, means for mov- 111g air to the reeds, sectional area of said ing each of said slides independently, and means for simultaneously operating all the slides.

6. A reed organ having ports for supplying air to the reeds, slides for varying the sectional area of said ports, a bell crank, for each slide, having an arm engaging the slide and adapted to be displaced by a key, and means for simultaneously operating all the slides.

7. I1 reed organ having ports for supply slides for varying the sectional area of said ports, a bell crank, for each slide, having an arm engaging the slide and adapted to be displaced by a key, and a rail pivoted in the frame of the organ for simultaneously operating all the slides.

8. A reed organ having ports supplying air to the reeds, slides for varying the sectional area of said ports, a bell crank, for each slide, having an arm engaging the slide and adapted to be displaced by a key, a rail pivoted in the frame of the organ, and an adjustable projection on the rail for each bell crank adapted to engage the latter and move it.

9. A reed organ having ports for supplying air to the reeds, slides for varying the sectional area of said ports, a bell crank, for each slide, having an arm engaging the mg air to the reeds.

slide and adapted to be displaced from a key, a rail pivoted in the frame of the organ, and an. adjustable projection on the rail for each. bell-crank adapted to engage the latter, when the rail is turned on its pivots.

In testimony that I claim the foregoing as my invention, l have signed my name in presence of two subscribing Witnesses.
