The mute con- M Which is closed Further, a1- shown as disposed longibody, it is evident that they may though the strips are tudinally of the in various arrangements as is found to be most expedient for the use intended.

As shown best in Figure 2, the base It is provided with an and is provided with a finger-grip ring 34 by which the rod may be manipulated as set forth hereinafter.

provided with aligned, axial apertures through 32 extends,

rod 28 between the abutment 24 and the nut 42, and serves to yieldingly bias the parts into their extended position as shown in Figure 1.

In order to clamp and lock the parts into their closed position as shown in Figure 2, the detachably secured thereto, as by screws 46, a pair of vertically disposed standards 48 whose upper ends terminate in laterally but oppositely disposed flanges 50. Depending from the lower surface of the member 40, are a pair of downwardly's struck lportionsi-BZ whichiprovide straps for receiving the flanges-=50 when the'mute cover 36 is rotated relative to the base I4, as indicated by the arrows 54 in Figure 3.

From the foregoing, the operationiof-theldevice will be readily understood. "The mute is inserted in the mouth of the horn'iI-z, andiis retained therein by the frictional engagement of the strips 20 upon the inner suriace'oftheihorn. The spring 44 normally urges the member .36 .to its open or outer position as shown in Figure 1. In order to vary the tonal characteristics otthe horn it is merely necessary to grip the fingergrip portion -34 .andpress 'thereon to :urge .the mute cover 36"inwardly-, to thereby' va-ry theeffective opening or clearance: between .the end: of the 'horn I2 and thelcover-fifi, thusemodifyin-g and lmullling lthe $01131 qualities of the .horn. When it is desired to closetheltmute, either-when mounted upon thehornaor when" removed themirorn, it is :merely necessary .to rotatelthe cover 36 relative .to z the: base I4 -.in .the direction-of .the arrows indicated in Figure :3 -atz-54, whilewiepressing the cover 36 lupon .the base againstlthe opposition of the spring 44, whereupon the flanges 50will engageinwthe straps 52 'for locking the parts in their .closedrpositiorras shown in Figure .2.

v."Attention is: next: directed ate the: embodiment of ,.the .1 invention shown .in Figures l through .8. In this form or the invention ;.the numeral .IH) designates 1 generally the entire mute assembly which is shown attached .to the, flared open .end H2 oi rarmusical instrument. -.-The mute .consists of a body II4 whieh-is a:hollo-wtconehaving adetachablebase H5 and a truncatedopenrend I-IB.

The gasket sections may be suitably attached the like to either the bead I46 or the cover I40, or to the adjacent rimofthe horn I I2.
