TUNING ATTACHMENT FOR WIND MUSICAL IN$TRUMENTS.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed February 20, 1918. Serial No. 218,343.

' State of Indiana, have invented certain new anduseful Improvements in Tuning Attachments for IVind Musical Instruments, of which the followin is a specification.

This invention re ates to wind musical instruments particularly of the reed type and the object of the invention is to provide an improved means whereby the air column may be lengthened or shortened for the purpose of tuning.

While the invention is applicable to different forms of reed instruments, itis particularly adapted asa mouthpiece adjustment for saxophones.

I provide means whereby the instrument may be rendered flat or sharp by simply manipulating a threaded collar or sleeve.

I have provided means whereby the mouth-' piece may have longitudinal movement lm parted to it without any rotative movement with respect to the main portion of the instrument. I have also provided means whereby the attachment may be readily applied to existing instruments without unduly altering them.

In the"drawi11gs Figure 1 is afragmentary side elevational view of a saxophone to which my invention is applied;

Fig. 2 is a longitudinal sectional view through the tuning attachment, the parts being separated;

Fig. 3 is an end view of the instrument part, separated on the line 3-3 of Fig. 2;

Fig. 4; is a sectional view on the line 4-4 of Fig. 2; Fig. 5 is a fragmentary side elevational View of the tuning attachment; and

1 Fig. 6 is a longitudinal sectional view at right angles to the section shown in Fig. 2.

Referring now to the drawings, 1 designates the tubular end of an instrument, for example saxophone to which my invention is applied, said end being provided with external screw threads 2 and having in its end wall a plurality of guide receiving openings 4 and 5. 7 represents a thin tube that serves as a' liner for the tubular end 1, and preferably also as a liner for the mouth-piece 6. The tube 17 carries an internally threaded sleeve or collar '8 having knurled portions 9 and 10 and adapted for rotative movement on the tube 7 butheld against longitudinal movement with respect thereto by the shoulder 11. A collar 16 having threaded engagement with sleeve 8 serves to hold the tube 7 in abutting relation with the sleeve 8. Collar 16 is retained in place by set screw 17. The internally threaded portion of the sleeve o is spaced away from the tube 7 to provide an annular guide in which the instrument end 1 may travel, and by which said end may be confined and guided while the tube 7 is acting as a liner for said end. Within this space are the longitudinally extendin uide pins .12 and 13 rigid with the should dr 11 fixed on the tube 7 so that when said pins enter the openings 4. and 5 the tube 7 will be held against rotative movement with respect to the end 1, and inasmuch as the mouthpiece 6 is carried by the tube 7 rotative movement of the mouthpiece will be prevented. An internally smooth flange 8 on the sleeve 8 receives the end I of the instrument and guides said end to receive the liner tube 7 Within its bore and the pins l2, 13 Within its openings 4:, 5; and also directs the threads 2 to the annular confining space between the sleeve and liner tube. Ihe described organization of parts not only aifords a more substantial constructionbut a more convenient assembly, since it is only necessary to insert the threaded end of member I within the flange 8 and to turn the mouth-piece and sleeve together until the pins l2, 13 seat themselves, which will arrest the mouthpiece in proper position, whereupon contin ued turnin will be limited to the sleeve alone and. te mouth-piece and tubular end,

while retaining proper relation to each other, may be given relative longitudinal adjustment at will.

,The sleeve 8 is turned in the'direction of the initial S (Fig. 5) to shorten the air column and sharpen the tone of the instrumerit, and in the direction of the initial F change of pitch may be accomplished with one hand of the player by simply turning the sleeve 8 in the proper direction. Being relatively thin, the liner tube 7 makes no dislid instruments comprising a tubular instrument end, a liner tube having an axially sliding hearing within said instrument end,

and a sleeve surrounding said liner tube but "separated therefrom and providing therewith an annular space extending substantially the length of tuning adjustment and fitting the instrument end, said liner tube and sleeve being united beyond said annular space by a bearing that permits turning but resists axial movement of the sleeve upon the liner tube, means being introduced between the sleeve and instrument end that translates a rotary movement of the one, into an axial'movement in the other, and connection being provided between the liner tube and the instrument end which permits axial movement but resists rotation between them.

2. A tuning. connection for two parts of a wind musical instrument comprising a liner tube adapted to carry the one and to slide axially within the bore of the other of two instrument partsto be connected, and having a pin and openingengagement that prevents relative rotation on the instrument art in which it slides, and a sleeve surrounding the liner tube but separated therefrom and forming therewith an annular space adapted to fit the end of the instrument part in which the liner tube slides, said sleeve having a feeding screw thread engagement with said last-named instrument part through which it develops relative sliding movement between the latter and the liner tube.

3. A tuning a wind musical instrument comprising a connection for two parts ofliner tube adapted to carry the one and toslide axially within the bore of the other of two instrument parts to be connected, and having a pin and opening engagement that prevents relative rotation on the instrument part in which it slides, and a sleeve sur-v rounding the liner tube but separated therefrom' and forming therewith an annular space adapted to fit the end of the instrument part in which the liner tube slides said sleeve having a feeding screw thread engagement with said last-named instrument part through which it develops relative sliding movement between the latter and the liner tube; said sleeve also having a longitudinal extension that receives the end of said instrument part guides it to the feeding screw threads and positions the parts to insure the pin and opening engagement in the assembly of the parts. a

4. In a tuning connectionfor the tubular parts of wind musical instruments, a liner tube having portions inserted within the bores of two parts to be connected, and having an axial sliding movement in one of said parts, a sleeve having a shouldered bearing 'upon said liner tube at a point intermediate its inserted portions and extending from said bearing axially over the sliding inserted part of said liner tube but separated therefrom and forming therewith an annular space that receives the instrument part in which the liner tube slides, means carried by the sleeve to develop. said sliding movement of the line tube in which it slides, and means carried by the liner tube to resist rotation of the instrument part that receives it.

The foregoing specification signed at Elkhart, Indiana, this 9th day of November, 1917.
