UNITED STATES GEORGE BAUER, OF ST. LCIUIS, MISSOURI.

TONE AMPLIFIER.

Application filed March 23, 1925. Serial No. 17,668.

To all whom it may concern Be it known that GEORGE BAUER, a citizen of the United States of America, residing at St. Louis, State of Missouri, has invented certain new and useful Improvements in Tone Amplifiers, of which the following is a specification.

The object of my device is to make a tone amplifier to be used in musical instruments, particularly wind instruments. A more specific object is to make a tone amplifier to be used in mouth pieces of musical instruments, such as clarinets.

Owing to the difliculty in procuring the proper reeds in order to produce sounds of the desired intensity and volume, I have provided my device. lVith the use of my device and a reed that Will produce a tone of very small intensity, a tone of much greater intensity and volume may be produced. My device will not distort the sound nor in any manner mar its purity. My device is made simply, of inexpensive material, and may be easily applied or removed. With these and other objects in view, my invention has relation to certain novel features of construction and arrangement of parts, as will be hereinafter more fully de scribed, pointed out in the claim and illustrated in the drawings, in which- Fig. 1 is a longitudinal sectional elevation of my device, and

Fig. 2 is an end elevation of my device, and

Fig. 3 is a plan viewof the blank for my tone amplifier, that is to say, it illustrates the tone amplifier before the securing arm has been bent, as shown in Fig. 2.

For the purposes of illustration, I have shown a clarinet mouth piece. Numeral 4 designates the body portion of the mouth piece having the smaller end portion 5 and the cork covering 6. By means of the smaller end portion 5, the mouth piece is secured to the clarinet (not shown) by frictional engagement. The opposite end of the mouth piece is tapered, as shown at 7 and slotted in its bottom portion. Numeral 8 designates a conventional reed which is secured to the body portion 4 of the mouth piece by the strap 9, which is fastened to the body por tion 4 over the inner end of the reed 8 by means of the screws 10. The structure thus far described is conventional. My tone amplifier consists of a single piece of stamped metal, preferably made of German silver, or metal having similar qualities and is bifurcated, providing the two prongs 11 and 12. The end 18 is bent as shown at 14 in Fig. 2. The bent end 15 has a tapped hole formed therein. The wall of the body portion 4 has a tapped hole 16 formed therein. The screw 16 is screwed into the tapped hole 16 into the hole in the bent end 15 of n y tone amplifier. By this means the tone amplifier is suspended within the body portion 4 and in the sound path. The amplifier is so positioned that the plane of the prongs 11 and 12 forms an angle of substantially with the plane of the reed 8. This is a critical angle. Placed at any other angle the amplifier will not function efficiently.

What I claim and mean to secure by Letters Patent is,

In combination with a mouth piece having a reed, a tone amplifier secured in said mouth piece, the plane of the amplifier being disposed at an angle of 45 with the plane of the reed of the tone amplifier.

In testimony whereof I aiiix my signature.

GEORGE BAUER.
