KEYED MUSICAL WIND INSTRUMENT.

A spring of the usual arm 17 which liberates the tampion of G type tends to hold arm 17 down and consesharp Gr sharp which is therefore raised in quently tampion 1 is maintained in the its turn. On releasing the spatula of C 55 down position as long as ring 5 Fig. 1) is sharp G sharp reverse action takes place and the pointed support of C sharp G sharp and the spatula assume their original position.
In Figure 7 which relates, to the same mechanism, the modification has the'foll'owing form 7 Between the enlargements 24 and 25 the hinge is divided into two parts. The spatu- 1a 10 of C sharp G sharp is subject to the action of the hinge 1 and the pointed support of G sharpand the heel 55 is subject to the action of the hinge 2'. As in Figure 7 4, there is a rockable member 53 and a pivot 52, these parts remaining unchanged. The difiierence, however, is that the heels 10 and 55 are applied to the rockable member in the reverse direction,from the direction ofFigure 2, that is to say, from behind. The pointed support of C sharp G sharp is under the actionof a weak spring which causes it to lift. The spatulaof C sharp Gsharp is under the action of a spring which is suf ficient only to lift it and which by its heel bears on the'rockable member which at its end acts on the heel 55, the later being rigid with the pointed support of C sharp G sharp and which annuls the action of its spring and causes it to'close. Consequently, when the spatula 10 is lowered the spring of the pointed support of G sharp is freed and the latter is raised.
What is claimed is I 1. In a keyed musical wind instrument, a tamp-ion, a controlling lever for the tampion, an operatinglever pivoted on an axis, and a rockable member pivoted on the instrument and adapted to be actuated by the operating lever to actuate the controlling lever.
2. In a keyed musical wind instrument, an axis comprising a plurality of hinges, an operating lever pivoted on one hinge, a tampion, a controlling lever for the tampion pivoted on another hinge, a roekable member pivoted on the instrument and adapted for actuation by movement of the operating lever to in'turn actuate the controlling lever.
