13 Claims.

This invention relates to the tuning of musical instruments, and is illustrated as embodied in clarinets or the like having improved tuning means.

An object of the invention is to provide a simple and accurate means for tuning such an instrument by shifting axially relatively to each other telescoping sections of the instrument, thereby changing the eiective length of the air column, the tuning means preferably being arranged to limit the separation of the sections in the normal tuning operation to prevent unintentional disengagement of the operating mechanism.

The telescoping sections of the instrument are shown provided with means, such as oppositelydirected (i. e. right and left) external threads, engaged by operating means (such as correspond ing internal threads) carried by a tuning collar or sleeve which surrounds and substantially conceals the telescoping portions of the relativelyshiftable sections. One feature of the invention relates to facilitating the assembly of the parts by making the thread on one section of smaller diameter than that on the other section, the internal threads on the collar being of corresponding different diameters.

An important feature of the invention relates to the provision of means, preferably normally concealed by the collar, for limiting the separating movement of the telescoping sections to prevent unintended disengagement of their threads from the operating threads of the tuning collar or sleeve. At least in one position of the collar, however, the separation-limiting means should be accessible so that it can be rendered inoperative when the instrument is being taken apart.

I prefer to mount a radially projecting part removably on one of the telescoping sections within a slot on the other section, and the collar may then be formed with an opening which alines with, and permits the removal of, the projection in one position of the collar. In the arrangements illustrated, one of the telescoping sections has a keyway interrupting its external thread and receiving a guide key or the like carried by the other section, the key having the slot embracing the removable radial projection to limit separation of the sections.

Another feature of the invention relates to shortening the tuning mechanism by arranging the mouthpiece receiver with a tongue or key, arranged to seat in a lqeyway as described above, spaced radially outside the inside slide, so that (Cl. 84E-386) the outside slide of the body tenen receiver ts between the tongue and the inside slide.

The above and other objects and features of the invention, including various novel combinations of parts and desirable particular construc- 5 tions, will be apparent from the following description of the illustrative embodiments shown in the accompanying drawing, in which:

Figure 1 is a side elevation of the upper or mouthpiece end of a wood clarinet provided with one form of my improved tuning means;

Figure 2 is a bottom plan view, looking in the direction of the arrows 2 2 in Figure l, but with the tuning collar or sleeve broken away in central section to show the parts inclosed the-rein;

Figure 3 is a partial section on the line 3-3 of Figure 2;

Figure 4 is a detail of part of Figure 3 on a much larger scale;

Figure 5 is a partial side elevation of a metal clarinet provided with a somewhat diierent embodiment of my invention;

Figure 6 is a plan View ther-eef, looking in the direction of the arrows @-5 in Figure 5, and with the tuning collar brok-en away in central section;

Figure 7 is a partial section on the line l-l of Figure 6; and

Figure 8 is an elevation, partly broken away in central section, showing a third embodiment.

The clarinet illustrated in Figures 1 3 includes an instrument body I Ei, and a mouthpiece l2 intended for use with a reed (not shown), connected by novel tuning means for shifting these parts relative to each other axially (i. e. lengthwise) of the instrument to change the eiective length of the air column.

In the arrangement illustrated, the tuning means comprises telesooping sections l and l, formed at their ends with sockets or tenonreceivers into which lit respectively the usual corked tenons on the ends of the instrument body I0 and the mouthpiece i2, as shown in Figure 3. vIt will be noted that the lefthand end of section I6 is very thin, and telescopes inside oi the section I4, so that there is a substantially continuous and uniform-diameter wall inclosing the air column, in all positions of the tuning mechanism. These sections may, if desired, be built up by soldering thin-walled tubing to rings of heavier 50 material.

The end of the section i4 is formed with an external thread I8, interrupted at one point to provide an undercut keyway extending in the direction of the length of the instrument and slidjecting from a sleeve 22 pressed permanently onto (and if desired soldered or otherwise secured to) the section I6 against the shoulder Which forms the base of they socket receiving the end of the mouthpiece I2. The sleeve 22 is formed withY external threads 23 of somewhat greater diameter than the threads I8. The section IG thus in eiect carries, spaced radially outward therefrom, the key 20, and the section |4 is tted or nested between these two parts. makes for great compactness, shortening the entire tuning mechanism materially as'compared to earlier designs having the same range ofadjustment.

The threads I8 sleeve 22 are directed in opposite directions, one

being a righthand thread and the other being'Y a lefthand thread, and they are engaged by corresponding right-and-left'internal threads 25 of two corresponding different diameters formed on a part 2l@ permanently secured in the interior of a tuning collar or sleeve 26 which normally incloses and protects the telescoping portions of the sections |4 and |6 throughout their entire lengths. The difference in the diameters Afacilitates assembling the parts.

ysetscrew or the like32 if desired, which in one position alines with the stop pin 30 and through which the stop pin can be removed when the instrument is being taken apart. The ends of collar 26 may be protected by suitable ferrules 34.

The arrangement illustrated in Figures 547 is Y substantially as described above, except that it is designed for use with a metal clarinet or similar instrument. Parts correspondingv to parts in Figures 1 4 are indicated by the same reference characters increased by 100. The principal difference is in the size of the parts; however, theV thread-carrying sleeve |22 is illustrated as integral with the section ||6, anda separate thin tube I I1' soldered thereto forms the portion telesccping into the section ||4. Inlthis/arrangement, the pin |30 becomes accessible (for removal) beyond the edge of the collar |26, when collar |26 is turned to bring the pin |30 into the extreme lefthand end of the slot |28.v

Figure 8 illustrates an arrangement which is Vthe same as that in Figures l-3 except that a protecting sleeve 234, surrounding the end of the collar 26, is integral withV a telescoping section 2I4 which may otherwise be of the same construction as the section |4. In this arrangement, turning the collar 2 6 makes the adjustment in the same manner as in the embodiment of `Figures l-4, but the end of the collar is covered by the sleeve 234.

It will be noted that the above-described construction provides a relatively long and easilyY manipulated tuning collar orsleeve, 'that in all of the joints the inside part points toward the lower end ci the instrumentV so that moisture This yand the threads 23 on the ably receiving a guide key 2E! carried by and procannot work into the joints, that the means for keying the sections together does not interrupt the internal surface of the instrument as in some prior constructions, that a wide range of adjustment is provided with a very short tuning mechanism, that permanent attachment of intricate parts to the instrument body is avoided, that there is no substantial interference with the resonance of the instrument lby loose or doubled parts or the like, and that the tuning mechanism iseasily and accurately operated and is not expensive to manufacture.

While several illustrative constructions have been described in detail, it is not my intention to limit the scope of the invention to those particular constructions, or otherwise than by the terms of the appended claims.
