Anothe object of the invention is to provide 2 an improved octave control mechanism composed of few parts adapted for convenient assembly and of pleasing appearance, and mechanism of the class described in which the number of soldered The lever 8 is of curved form and bifurcated or;

3 looped inwardly of its outer end, with the sides or branches of the loop or bifurcated portion straddling the outwardly extending arm of the spar it! and thereby effectively prevented from being bent or misaligned in the use and handling of the instrument. The octave valve or pad 'I is fixedly secured to the inner side of the outer end or" the lever B. lhe opposite looped or bi furcated end ll of the lever B is curved across the adjacent portion of the tubular body of the instrument, and by reason of its looped form, which surrounds or straddles the adjacent part of the tubular body, presents at the inner side of the tubular body an abutment at I2 for en gagement, for example, with an offset IS on the adjacent end of an actuating rod or element Hi.

The actuating rod or element I4 is operated by an octave key i5, and when thus operated swings the lever 8 counterclockwise (Figures 1 and 3) about its pivot ii to open the octave valve or pad 1'. The looped or bifurcated form of the lever B, in addition to being prevented from bending or misalignment by toe spar l provides a better balanced control for the octave valve. A thumb rest It is preferably soldered or otherwise attached to the tubular portion or" the instrument adjacent the octave key it, and the thumb rest it and key iii together are shown of generally teardrop form to present a pleasing appearance.

The leaf spring ll underlies the extending arm of the spar id and has one end abutting or secured at E8 to the inner side of the spar H), The opposite end of the spring I! abuts or is secured at I!) to the inner side of the outer end of the lever and the spring I! operates to hold the valve or pad l in closed position against the outer end of the rim of the octave hole and to return the valve l to closed position. With the spring arrangement described, the spring pressure or force is applied right up adjacent the valve or pad 7.

It will be from the foregoing description that with the present invention the attachment of the spar it] to the neck 2 constitutes the only attachment of the octave valve control mechanism to the tubular body of the instrument. The device is composed of few parts which are adapted for convenient assembl and are of pleasing appearance. The mechanism is adapted for operation expeditiously, and is relatively quicir and certain in action. Moreover the spring action is better, the octave lever is prevented from being bent or misaligned in use and handling of the instrument, and other advantageous results are provided.

The embodiment of the invention shown in the drawing for illustrative purposes only, and it is to be ex; ressly understood that said drawing and the accompanying specification are not to be construed as a definition of the limits or scope of the invention, reference being had to the appended claims for that purpose.
