11 Claims.

The present invention relates to a toy and it particularly relates to a childrens harmonica toy.

It is among the objects of the present invention to make a harmonica entirely molded of plastic materials which will stand rough usage and have as few elements as possible and which at the same time may be assembled inexpensively i from few parts.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes may be made therein by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects it has been found most satisfactory, according to one embodiment of the present invention, to form a harmonica of two casing elements, each casing element molded in one piece of plastic and an intermediate reed element also molded in one piece. These pieces are so formed that they may be readily assembled together with assurance of correct positioning in relation to each other.

The invention also consists in certain new and original features of construction and combination of parts hereinafter set forth and claimed and as to its other objects, features and advantages, the mode of operation .and manner of its organization, these, inter alia, may be better understood by referring to the following description considered in connection with the accompanying drawings forming a part thereof in which:

Fig. 1 is a top plan view of the harmonica upon the line I-I of Fig. 2;

Fig. 2 is a front edge elevational view;

Fig. 3 is an edge elevational view upon the line 3 3 of Fig. 1;

Fig. 4 is a back elevational view upon the line 4-4 of Fig. 3;

Fig. 5 is a transverse sectional view upon the line 5 5 of Fig. 2;

Fig. 6 is a transverse vertical sectional view upon the line 6-6 of Fig. 4;

Fig. '7 is a transverse sectional view upon the line 'I-l of Fig. 4;

Fig. 8 is an exploded perspective view showing the various parts before assembly; and

Fig. 9 is a top perspective view showing one method of forming the reed plates.

Referring to Figs. l to 9, the toy mouth organ consists of an upper casing member A, an intermediate reed plate B and a lower casing C.

The casing member A has the side members I0 and a central elevated portion I I curving upwardly to the rear as indicated at I2. The members |0 of casing member A interiorly have the depending end walls I3, the front walls I 4, the rear walls I5 and the inside walls I6 which form a cage around the depending studs or nipples I1.

The walls I3, I 4, I5 and I6 form a cage around the studs or nipples II.

The central portion II has the rear wall I8, the oblique wall I9 and the varying length walls 20 to 3| forming the sound chambers 32 to 44.

The lower casing member B has the end portions 60 and the central portion 6| sloping outwardly and downwardly as indicated at 62. The rear edge 63 is provided with spacer points 64 for contacting the reed plate B.

The side or end elements 60 have the end walls 65, the front walls 66, the inside walls 6l and the rear walls 68. The central portion 6| has the front wall 69.

Along the walls 61 and 69 are the ledges or l reed plate supports l0 and 'I|. 6l is notched as at l2.

Inside of the walls, 65, 66 and 6l, are the mounds 'I3 with the recesses I4 for receiving the ends of the nipples II.

The reed plate B has the alternately upwardly extending and downwardly extending reeds to |02 which cover the slots |03 to |I5. These slots increase in length from left to right as do the chambers 32 to 44. The end of the plate B has an outstanding lug III fitting into the recess or notch 'I2 which will locate it when the plate B is placed upon the ledges 'I0 and 1|.

The bases or roots |25 of the reeds 90 to |02 extend beyond the ends of the slots |03 to ||5 substantially to the forward and rear edges |26 and |2'I of the reed plate B. 'I'hey may be glued on or molded on integrally.

The reeds 90 to |02 as shown in Fig. 10 have oblique sides |28 and are slightly narrower than the slots |03 to |I5 as indicated by the spacing |29. Similarly the oblique ends |30 of reeds 90 to |02 are slightly short of the ends of the slots I 03 to ||5 as indicated by the clearance I3I. The enlargements |32 on the ends |30 of the reeds 90 to |02 will vary to give such weight to the reed as will produce the desired tone.

The elements A, B and C may all be molded integrally in the manner indicated in Fig. 9 which shows molding of the reed plates B by way of example. The reed plates B may be molded by injection molding. The device formed in the mold will have the form shown in Fig. 9 with the central inlet, section |50, the transverse flow section |5I, the nal inlet ilow sections |52 and the molded reed plates B. When the mold is opened, sections |50, |5| and |52 are removed and the reed plates B may be broken olf. The mold cavity may be made in sections correspond-A One of the walls ing to the number of sound chambers 32 to 44 and reeds 90 to |02.

In assembly, the edges of the walls I3, I4, i5, I6, I8, I9 and 20 to 3l, as well as the end of the nipple I'I are wetted with an adhesive or plastic solvent and then pressed against the sube assembly of the plate B and base C, A short contact will result in a permanent and durable connection.

As clearly appears, the harmonica of the pres-l ent invention, which may be made of three elements, namely the upper casing memberrA, the reed plate B and the lower casing C, by injection-molding of polystyrene, after cementing will form a substantially integral one-piece unit as shown in Figs. 1 to 4.

As. many changes could be made the above childrens toy musical instrument, and many ap-v parently widely different embodiments of this invention could be made without departing from ther scope of the claims, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
