EUGENE MEYER, OF NEW YORK N. Y.

RESONANCE noun Application filedAugust 14, 1922. Serial No. 581,762.

all w/wm it may concern Be it known that I, EUGENE MEYER, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Resonance Horns, of which the following is a specificatime i My invention relates to horns used either for receiving or transmitting sound vibrations, and consists essentially in the combination and incorporation, with such a horn, of one or morapreferably a plurality, of

sound amplifying resonant tubes, substantially in the manner and for the purposes herein fully set forth and described and claimed specifically.

In the. accompanying drawings I exempli'l y a practical embodiment of the essential features of my invention in conjunction with a conoidal horn of well known configuration, and show a plurality of resonant tubes positioned internally and radially around the inner concavo conoidal surface of said born, with the understanding that I do not limit myself to this identical form and construction of parts, since modifications may be resorted to in arrangement, and in minor details, with like result, and without deviating from the spirit and intent of my invention in this respect.

With this understanding,

Fig. 1, is a frontend elevation, of my improved resonance horn; I

Fig. 2, is a longitudinal section thereof taken upon plane of line 2-42, Fig. 1;

Fig. 3, is a diagrammatic representation of the inner surface of the born, the latter being presumed to be split longitudinally and spread out flat;

Fig, 4, is a diagrammatic elevation 'of the horn, howing its use as a means of making sound records;

Fig; 5, is a similar view illustrating its use in conjunction with phonographic sound box;

Fig. 6, is a similar view showing the horn adapted for use as a trumpet;

Fig. 7, is a detail view of an elbow suitable for use'as a coupling between horn and phonograph sound box.

5; sound vibrations is Well known, and do not claim anything original in this re spect, tue novelty in to present case can The function of resonance tubes in ampliopen extremities toward the apex end h, of

the horn.

Thus in Figs. 1, 2, and 3 of the drawings I show a series of resonant tubes 1 1, representing. thirteen notes of the musical scale,

eight natural from E to E inclusive, and the five intermediate notes Di, Ct, Al Gt, and Ft, although I do not limit myself in this particular, as any number, and cornbination and arrangement of resonant tubes, may be resorted to in adapting-the device to various purposes and uses.

Preferably the series of resonanttubes r, 1-, are arranged radially as shown, and as related to the apex of the horn; and may be afixed to the latter by glue, cement, or any other positive means.

S is a sound conveying tube or conduit, the main portion of which is positioned in alignment with. the longitudinal axis of the horn, said sound conduit S, being formed with a lateral extensions, protuberant through the side of the horn.

This sound conveying conduit S, is for the purpose of transmitting sound vibrations ineither directions. Thus, as shown in Fig. atpthe extraneous extension 8, thereof may be attached to a. record-producing device D, of well known construction, for making a record on the usual wax receiving disc d; or the outer end of the extension 8, may be placed to the ear of a person for the purpose of listening to sound vibrations received into the mouth of the horn, and modified and amplified by the'resonator tubes 1'1 01', a. phonographic sound box B, may be attached to the end of the horn, as indicated in Fig. 5, to transmit the vibrations imparted by the phonogra hi'c record P, through the horn in intensifie volume, a tubular coupling elbow e, such as indicated in Fig. 7, being used to connectthe box B, and the otherwise open apex end of the horn.

Or the apex of the vided with a mouth piece m, as indicated in Fig. '6, and the horn used as a speaking or singing trumpet if so desired. a fact horn H, may be pro I my sound amplifying horn may be adapted to many and various uses Without departing from the spirit and intent of my invention. What I claim as my invention and desire to secure by Letters Patent is,

1. The combination with a conoiclal horn of the character designated, of a plurality of resonant tubes, each for a definite note of the chromatic scale, positioned convergently therein, said tubes all having open ends facing the producer from the inside of the horn, the other ends being closed, substantially in the manner and for the purpose set forth.

2. A conoidal horn of the character designated, having a plurality of resonant tubes, each for a definite note of the chromatic scale, said tubes being open at one end and closed at the other, and positioned in the horn radially convergent thereto with their open extremities toward the apex of the horn, substantially in the manner and for the purpose set forth.
