This invention relates to musical instruments and more particularly to a musical instrument including a sound box for modifying the sound of a harmonica and adding other sounds thereto.

It is among the objects of the invention to provide an improved musical instrument including a sound box having a tubular harmonica support thereon so that the harmonica will be supported at a convenient position for playing when the sound box is held in the hands of the player, which sound box modifies the sound of the harmonica and is provided with a manually operated means for varying the volume of the sound as desired, which is provided with means, such as strings, to be manually plucked, for imposing other sounds onto the sound of the harmonica, and which is simple and durable in construction, economical to manufacture, and neat and attractive in appearance.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawings wherein: Figure l is a top plan view of a musical instrument illustrative of the invention;

Figure 2 is a longitudinal cross sectional View on the line 2-2 of Figure 1;

Figure 3 is a transverse cross sectional view on the line 3-3 of Figure 2;

Figure 4 is a cross sectional View on the line 44 of Figure l; and

Figure 5 is a cross sectional view on the line 5'5 of Figure 1.

With continued reference to the drawings, the sound box is a flat hollow body of elongated, rectangular cross sectional shape tapering symmetrically in width from its mid-length location to its opposite ends. This box has a flat bottom wall It! formed of a plate of wood or similar material and has two side Walls II and I2 marginally engaging the bottom wall In and secured to the latter by angle brackets IQ disposed internally of the sound box and a straight rear end wall M overlapping the rear ends of the bottom wall and side walls and secured thereto by suitable angle strips, as indicated at I5 in Figure 2.

A straight bar I6 of elongated, rectangular cross section is disposed in substantially parallel relationship to the bottom wall In of the sound box and spaced from this bottom wall so that the surface of the bar remote from the bottom wall is slightly within or below the edges of the side walls and rear end wall remote from the bottom wall of the box. This bar is secured at one end to the rear end wall I4 of the sound box and extends through the front end of the sound box between the adjacent ends of the side walls H and |2, the space from the bottom wall ID to the adjacent surface of the bar and between the front edges of the side walls being closed by a suitable front wall or block ll.

Intermediate the length of the sound box the bar I6 is provided with a rounded enlargement |8 having a circular opening l9 therethrough and the portion of the bar projecting beyond the front end of the sound box is shaped to provide a stringed instrument neck 20 and a head 2| at the end of the neck remote from the sound box. A plurality of tuning keys 22 are mounted in the head 2| and strings 23 extend longitudinally of the bar in position spaced from the surface of the bar remote from the bottom wall ID of the sound box. These strings are secured at corresponding ends to a tailpiece 24 mounted on the bar It between the opening l9 and the rear wall M of the sound box and are individually connected at their opposite ends to the tuning keys A nut 25 is mounted on the neck 20 at the end of the neck adjacent the head 2| to support the strings in spaced apart relationship above the adjacent surface of the neck and, if desired, a fret board may be mounted on the neck between the nut 25 and the adjacent end of the sound box.

A cover 26 in the form of a flat plate of wood or similar material and having a shape substantially the same as the shape of the bottom wall In of the sound box is hingedly connected at one end to the rear wall l4 of the sound box at the edge of the rear Wall remote from the bottom wall It by a hinge 21.

Reinforcing bars 28 and 29 extend transversely across the outer surface of the cover one near the hinge 21 and one near the front end of the cover and apertures are provided through the cover and these reinforcing bars one near each end of each bar. Suitable screws, as indicated at 30, are secured to the side walls of the sound box and extend through the apertures in the cover and the reinforcing bars and nuts, as indicated at 3|, are threaded onto these screws and bear against the outer sides of the reinforcing bars 28 and 29 to hold the cover firmly against the edges of the side walls H and I2 remote from the bottom wall I0. Suitable gaskets, as indicated at 32, formed of felt or similar material, are interposed between the cover 26 and the adjacent edges of the side walls of the sound box to provide a soundproof connection between the cover and the side Walls of the box.

The cover is provided with a circular opening 33 which registers with the opening IS in the bar l6 and provides access to the strings 23 for plucking the strings.

A rectangular plate 34 is mounted on the cover 26 adjacent the mid-length location and near one side of the cover, this being theupp r ed e or side of the cover when the instrument isheld in playing position by a right-handed player. The plate 34 is provided with an upstanding boss 35 of circular shape on the side of the plate remote from the cover 26 and the cover is provided with an opening 36 registering with the interior of the boss 35. A tube 37 of cylindrical shape has one end disposed within the boss 35 and-secured to the plate 34, this tube being inclined relative to the cover 26 in a direction outwardly of the cover and away from the edge of the cover remote from theplate 34. A second tube 38 is telescopically received in the tube, 31 and projects from the end of this tube remote from the cover 26 and a set screw 39 threaded through a tapped holein the tube 31 engages the inner tube 38 to hold this inner tube in adjusted positions rotationally and longitudinally of the outer tube 31.

At a location spaced'from the outer end of the tube 31 the tube 38 is provided with an elbow bend 40 extending through an angle of approximately 22 degrees and at its end remote from the tube 37, the tub-e 36is'reduced and flattened, as indicated at 4| in Figure 5.

A harmonica holding-clip 42 of channel shaped cross section has at the mid-length location of its web portion an opening receiving the reduced and flattened end 4! of the tube 38 and this clip is rigidly secured to the tube 38 by suitable means, such as soldering or welding.

A harmonica 43' is placed in the clip 42 and, when the harmonica is played, the sound from the harmonica will be directed by the clip 42 into the adjacent end of the tube 38 and will be conducted by the tubes 38 and 31 through the opening 36 in the cover into the interiorof the sound box of theinstrument.

The tubes 3'? and 38 and the clip 42 provide a tubular support for holding the harmonica 43 in convenient position to be played by a person holding the musical instrument in playing position.

An annular structure 44 providing a boss ,45 of circular shape is mounted on the cover 26 near the mid-length location of the cover and near the side of the cover remote from the plate 34 and the cover is provided with an opening 46 registering with the interior of the boss 45.

A tube 4? is secured at one end in the boss and extends from the structure 44.. substantially perpendicular to the surfaoeof the cover. 26., A conically shaped bell 48 is secured at its smaller end to the outer end of the tube '41 and the tube 47 and bell 43 together constitute a horn for the instrument.

A, cover plate 43 is secured to the wbell4tv at the larger endthereof andthis cover plate is provided with a rectangular opening'50 occupyingthe major portion of the area of the plate;

A flapper 51in the form of a flat rectangular plate, ispivotally connected. at one edge'to' the outer end of the bell 48 by ahinge-52in position to overlie the opening 58 in the cover plate-49.

An extension 53 on the portion of the hinge-52 secured to the flapper 51 projects outwardly of the rim or edge of the bell 48' at the larger end of the bell and a cord. 54 is secured atone-end to this extension and extends towards the coveritt A ring 55 is secured to the other end of the cord and a guide bracket 56 secured to the smaller end of the bell 48 and extending perpendicularly from the tube 47 at the corresponding end of the latter is provided at its end remote from the tube 4! with an eye 51 through which the cord 54 extends and which provides a guide for the cord.

By inserting a finger in the ring 55 a player can pull on the cord 54 to raiselthe flapper 5| away from the cover plate491and. uncover the opening as desired. The flapper returns to a position in which it is superimposed on the plate 49 by its own weight or, by a suitable return spring incorporated in the hinge 52.

With this arrangement, when the instrument is held in playing position the mouth of the player may be applied to the harmonica 43 held in the clip 42 and the sound of the harmonica will be transmitted through the tubular harmonica support into the sound box. One finger of the right hand of the player may be engaged in'the ring to control the flapper 5| While the thumb and; forefinger of this hand may hold a pick for plucking the strings 23 in the opening 33. The left hand of the player grasps the neck 25 of the instrument to press the strings 23 against the neck or fret board in a manner to provide the desired.

notes or chords from the strings.

The flapper 55 will control the volume of the sound produced by both the harmonica and the strings and may be used to give a rhythmic effect to the combined sounds.
