INDIANA, A CORPORATION or INDIANA TUNING DEVICE FOR WIND MUSICAL INSTRUMENTS Application filed September 8, 1931. Serial No. 561,677.

This invention relates to wind musical instruments of the reed type, and particularly to clarinets, saxophones, and thelike.

The principal object of my invention is to provide an improved, simplified, and cheap tuning device for a reed musical instrument of the class mentioned.

Another object is to provide a unitary tuning device and mouthpiece mount for a reed musical instrument of the class mentioned.

A third object is to provide a tuning device for saxophones, clarinets, and the like, that is simple, cheap, unitary, and which has a double telescopic connection with the mouthpipe f the instrument.

Other and more specific objects of the invention are mentioned and described herein.

The preferred embodiment of my invention is illustrated in the accompanying drawing, wherein Figure l is a side elevational view of a saxophone mouthpipe to which my invention is applied, the tuning device being illustrated in section;

Fi g. 2 is a top plan view thereof; and

Fig. 3 is a sectional longitudinal view of the'tuning unit alone.

Similar numerals of reference indicate like parts throughout the several views on the drawing.

Referring now to the details of the drawing the numeral 1 indicates the curved tapered mouthpipe of a saxophone to which the tubular cylindrical tip 2 may be secured, as an extension, bv soldering, or otherwise in any suitable manner. The numeral 3 generally indicates the tuning device or unit which may comprise the tubular tapered body member 4, the sleeve member 5 concentric therewith, and the clamping screw 6, said body member having a cork sleeve 7 mounted ex-` teriorly thereon to telescopically engage the mouthpiece 8 (indicated in dotted lines), as is well known in the art.

The sleeve member 5 is provided with the annular inturned flange portion 9 adjacent the forward end thereof which is rigidly secured to and about the exterior of the body member 4 by soldering, or otherwise in any suitable manner, whereby said sleeve member,

whichvis shorterr than the inner tubular meni- A ber 4, is concentrically mounted in spaced relation to the member 4 andfora fraction of the lengthof the latter and provides an open end chamber 10 within which the mouthpipe tip 2 is Vslidably and removably mounted.

The kcork sleeve V7 encompasses that portionV of the member 4 which projects beyond the sleeve 5 and may contact with the sleeve flange 9, or terminate adjacent thereto, the outer end of said cork sleeve being engaged by the hook-like flange 11 of member 4 to prevent longitudinal displacement of said sleeve. A grip ring 12 may be formed on Ethe exterior ofthe sleeve 5 adjacent the forward end thereof to facilitate longitudinal sliding movement of the tuning unit 3 on the mouthpipe tip 2.

Means for clamping the tuning unit 3 Il adjustment with the mouthpipe tip 2 may be provided.- Y Y As illustrated, such clamping means comprises a headed clamping screw 6 and lugs 13 and 14 rigidly mounted upon the sleeve 5 upon opposite sides of the slit 15 formed in the end of said sleeve, said screw extending through a drilled hole in lug 14 and into screw threaded relation with lug 13, and said screw having an annular shoulder 16 in engagementV with the, lug 14, whereby said clamping means functions as a ligature for pinching the inner end of the sleeve 5 against and about the mouthpipe tip 2.

In the application and operation of my improved4 tuning device the unitv 3 is slidably mounted uponthe mouthpipe tip 2, in which position the tubular slidably engages'withi'n the bore lof said tip,

Vandsleeve 5 engages about the exterior of said mouthpipe tip, in which relation with the tip 2 the tuning unit 3 is manually slidable upon said tip to eEect the desired pitch change. When the desired adjustment of the unit 3 has been made it may he rigidly maintained by the clamping action of the screw 6.

I cla-im: j

1. A tuning unit for reedmusical instruments comprising inner and outer tubular members rigidly connected together in spaced concentric relation and providing an open end chamber between said tubular members.

2. A tuning unit for reed musical instruments comprising inner and outer tubular members rigidly connected together in spaced 5 concentric relation to provide an open end chamber extending about said inner tubular member, said inner member extending beyond the end of said outer member.

3. A tuning unit for reed musical instruments comprising inner and outer tubular members rigidly connected together in spaced concentric relation and providing an open end chamber therebetween, said inner member eX- tending beyond the end of said outer member and provided with a nonmetallic sleeve.

4c. A tuning unit for Areed musical instruments comprising inner and outer tubular members rigidly connected together in spaced concentric'relation and providing an open en d chamber therebetween, said outer tubular member being shorter than said inner member, and clamping means carried by said outer tubular member.

5. The combination with the tubular end of the. mouthpipe of a reed musical instrument, of a unitary tuning unit and mouthpiece mount slidablyk mounted upon said mouthpipe and effecting inner and outer telescopic connection therewith.

6. The combination with the tubular end of the mouthpipe of a reed musical instrument, of. a longitudinallyv chambered combined tuning unit and mouthpiece mount slidably mounted upon said mouthpipe and effecting a telescopic connection with both the bore and exterior of said mouthpipe-end, and clamping means carried by said tuning unit.

7. A tuning unit for reed musical instruments comprising inner and outer tubular.

members rigidly connected together in spaced concentric relation and providing an open end chamber between said tubular members, said chamber being adapted to be occupiedby the tubular mouthpipe of the musical instrument,

said outer tubular member being provided With screw clamping means.

l8. A tuning unit for reed musical instruments comprising inner and outer tubular members rigidly connected together in spaced concentric relation and providing an open end chamber therebetween, said inner member extending beyondthe end vof said outer member and provided with a non-metallic sleeve, said outermember being longitudinal- 55 ly slit at its free end, and screw clamping means coacting with the slit in said outer member.
