UNITED STATES GEORGE B. DUSINBERRE, or WELLSBORO, rnimsrnvanm.

Application filed October 532, 1926. Serial No. 143,407.

The present invention is oirected to atype of musical instrument generally known as the jewsharp and which relies for its production of musical tones upon a vibrating tongue or reed located between two rigid members and held against the mouth or the in which a rigid frame construction of stamped metal is utilized.

A further object ot the present invention is the provision. of a protective cover for the vibrating portion of the instrument.

A still further object of the presentin vention is to provide a finger guide to insure proper manipulation of the reed.

It is a still further object of the present invention to provide an improved method of fastening the reed in the frame.

Further objects will be apparent from the following specification and drawings which are illustrative of one embodiment otnthe invention. i i

Fig. 9 is a sectional view of a modified form of the instrument.

In the embodiment disclosed in the draw ing, the instrument comprises a stamped metal reed plate ltormed with depressed channels 2 which give the necessary rigidity and strength to the plate. These channels of depressions on the sides as shown, or the channeled portion may be carried around the ends so that a continuone channel is formed entirely around the plat s. this latter form of channel being desirable it relatively thin material is used the base plate. The channels 2 besides forming strengthening members for the base plate 1 act as rests against which the teeth the player are placed so thatthe instrument may be properly located with respect to the oral cavity. [1 narrow tapering open- 3 is formed in the reed plate between two channel portions 2 in wh ch a vibrating reed 4 is mounted.

As shown in Figs. 8, 4- and 6 the inner end of the reed 4 is fastened to the reed plate 1 by cutting the metal of the base plate with two parallel cuts 5, 5 and then tongues'by a third cut of the metal ated 6. The two tongues 7, 7, thus ied may be deformed or pressed down ie vibrating reed 4 after the same has been placed in position thereby holding it r' 'dly with reference to the reed plate and are slot 3. I

Figs. 7 and 8 illustrate a slightly modified manner of attachin the reed which consists in stamping out tongues 8, 8 out of the charmel or

ridge portions

2, 2 which tongues an be subsequently folded or deformed over the end of the reed after the same has been placed in its proper position with respect to the reed plate 1. Various other methods of fastening the reed to the base plate may 0 e employed such as spot welding or riveting.

A cover 9 also formed of sheet metal may be provided, which cover is of substantially inverted li-shape and is formed at its lower one with reentrant flanges l0. 10. These reentrant flanges i'orm channel or guide for the reception of the reed plate i and in the form shown, permit the cover to be moved rela to the reed plate along the axis thereof. The reed 4 of the instrument has anoperative upstanding member 11 which is manipulated by the linger oi the player to set the reed in vibration and the height oithe inverted i -shaped cover 9 is such that when the cover is entirely in place over the rced plate it will entirely cover the reed and its upstanding portion 11 thus protecting the delicate portions of the instrun ,nt from injury which makes it possible arry the instrument in the pocket with- 1 damage. The position. at i is caused to vibrate freely, the finger always this purpose is shown in the sectional view of Fig. 5.

When it is desired to play the instrument,

the cover is moved with respect to the reed plate into a position in which operative upstanding portion of the reed 11 is about a quarter of an inch from the cover 9, this position being shown in Fig. 1. In this position the finger of the player is guided'properly against the reed tip 11 so that the reed hitting the reed tip properly without the care and practice that is necessary with the conventional typev of jews harp.

In the embodiment described the cover is guided with respect to the reed by the parallel sides ofthe reed plate '1'" butthe reed plate might in certain embodiments partake of. other sha Jesthan one with parallel sides two separate stren thenin channels. .l a c: 7

i the which would of course necessitate thense' of other methods of mounting movable cover 9 on the reed plate.

A modification of the reed plate structure them.

Obviously the invention is not limited to mechanical details herein vention as defined in the appended claims.
