UNITED STATES CARL J. SCHMITT, OF BROOKLYN, NEW YORK.

HORN.

Application filed May 17,

To all 'w hom t may concern Be it known that I, CARL J. SCHMITT, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Horn, of which the following is a specification.

My invention relates to horns and has for its object to provide a horn adapted to influence a vibrating air column in such a manner as to increase the pleasurable sensation desired to be produced on the auditory nerves. For purposes of illustration, my invention has been shown as applied to the amplifying or reproducing horn of a phonograph.

Other objects of my invention will be apparent from the following description and from the accompanying drawings of one embodimentthereof, in which- Figure 1 is a longitudinal vertical section through a phonograph horn'and its enclosing cabinet;

Figure 2 a lateral section of the horn shown in Figure l following approximately the center of the horn and showing the face of the attaching block; and

Figure 3 a top perspective of the upper edge and a portion of the top of the horn shown in Figure l illustrating the nature of the wood from which the horn is made.

Similar reference characters refer to similar parts throughout the drawings.

It is well known that the different sounds produced by musical instruments are due in part to the length, shape, size, and materials of the vibrating bodies from which the air waves originate or from the tubes or horns which influence the vibrating air cohnun. M inventionrelates to a tube or horn for in uencing a vibrating air column, formed of a resonant or sonorous wood which so affects the air column as to increase the pleasurable sensation produced on the auditory nerves. The shape, construction, and mounting of the horn embodying my invention, in addition to the material of which it is formed, also contribute in some instances to the result desired. An important feature of my invention is the material of which the horn is constructed. I have discovered that a resonant or sonorous wood having a comb grain, in which hard portions L alternatewith soft portions s, gives exceptionally fine results, particularly when the grain runs lengthwise 1919. serialNo. 297,830.

of the horn with the edges of the grain eX- posed. Figure 3 is intended to illustrate a wood having such a comb grain. Among woods which have been found suitable may be mentioned American spruce, although other woods having like characteristics may be used.

Although not limited thereto, I have chosen for purposes of illustration to embody my invention in the horn of the conventional cabinet form of phonograph of the so-called enclosed horn type. The embodiment disclosed therein is shown as a horn 1 formed of resonant or sonorous wood and preferably curved on all sides, mounted in a portion 2 of a conventional phonograph cabinet. Although if desired the horn may be made in one piece, it is shown in this embodiment as composed of a plurality of sides which preferably may be joined with a tongue and groove construction and preferably secured together without the use of nails, as by gluing. A multiple piece horn generally Vis easier and less expensive to manufacture than a horn made in one piece.

The beneficial results obtained from the use of the resonant or sonorous wood may be increased in some instances by the shape, construction, and mounting of the horn. Thus the bell or exit of the horn may be formed with an outward Hare. The bottom portion may have a slight upward curvature at the bell or exit. The bottom may be thicker at the ends than near the center, with the place of minimum thickness preferably nearer the smaller or entrance end of the horn than the larger or exit end. The horn may be suspended onl from the smaller or entrance end as in a lock 3, or the larger or exit end also may be supported against a non-rigid material 4, as for eX- ample felt.

Many modifications of my invention will be apparent to those skilled in the art without departing therefrom or from the scope of the claims, my invention consisting in providing a horn of resonant or sonorous wood and shaped, constructed, and mounted so as to increase the pleasurable sensation produced on the auditory nerves by thev vibrating air column inuenced thereby.

What I claim and desire to secure by Letters Patent is:

l. A horn formed of resonant wood and having the bottom thereof thicker at the exit end than near its center.

2. A horn formed of resonant Wood and non-rigid material against which the eXit having the bottom thereoic of varyingthickedge of said horn is pressed. v ness, the pla-ce of minimum thickness being In testimony that I claim the foregoing, 10 nearer the entrance end than the exit end, I have hereunto set my hand this 16th day 5 but removed therefrom. Y of May, 1919.V Y 3. A horn formed of resonant Wood and means to support said -horn comprising zt Y CAR-L J. SCHMITT.
