More particularly describing the invention, reference numeral 11*.generally indicates a mounting base, 12 a plucking disk or wheel and 13 a musical comb.

The mounting base is adapted to support the comb and the plucking disk in substantially parallel relation with the comb disposed at an angle such that the ends of the vibrators of the comb are arranged substantially along a radius of the plucking disk.

The mounting base includes a base body 14 and a pair of arms indicated by 15 and 16. The arms converge and terminate in a substantially circular disk supporting boss 18. A depending post 19 is provided on arm 15 to support the structure on a sounding board 20 shown in broken lines in certain of the figures.

The plucking disk 12, which may be of any suitable material,-is provided with downwardly projecting plucking elements 22 and with peripheral gear teeth 23. The disk is supported upon the boss 18 of the base and rotatably secured thereto by means of a rivet 25 and a spring, disk-mounting spider 26 which is slightly compressed when the parts are assembled. This construction provides a stable mounting for the disk 12 and yet permits rotation thereof.

For the purpose of driving the disk a shaft 28 is provided mounted in a suitable bore 29 in the arm 16 of the mounting base, the arm having a boss 30 at this point. The shaft may have a crank handle (not shown) at its outer end' or be otherwise driven. On the inner end of the shaft is gear wheel 31 which is rotatable on the shaft. The gear wheel includes a base portion 32 from which extend a plurality of circumferentially spaced peg-like projections 33 which act as gear teeth and mesh with the teeth 23 on the disk for the purpose of driving the same. A spring 34 about the shaft'having an end 34 hooked around one of the projections 33 of the gear wheel serves as a driving connection between the shaft and the wheel. When the shaft isrotated in the desired direction the gear wheel is driven, but if rotated in a reverse direction the spring loosens, permitting the shaft to rotate.

The mounting base 11 is provided at each end with relatively fiat extensions 35 which are apertured at 36 forthe purpose of receiving rivets to secure the mounting base and its carried elements to a sounding board member 20. 1

The mounting base body 14, inwardly of the extensions 35, is recessed at 38 on its under surface to provide a space for the mounting of the music comb 13. The comb itself is shown as being formed from a single piece of material as metal, and includes a base portion 40 and vibrators %1. The base portion is adapted to be mounted against the comb mounting surface 42 of the recessed portion 38 on the under side of the mounting base body 14. In Fig. 4 we show the comb secured by a clamp 43 which is arcuate in cross-section, and placed against the comb with the concave side adjacent the comb. The clamp and comb base are suitably apertured to receive rivets 44 for securing the parts together.

While good results are obtained with the recessed comb mounting surface 42 formed flat, in Figs. 6 and 7 we show another type of mounting for the comb. Referring to Fig. 6 the comb mounting surface, here indicated by numeral 42a, is shown as being generally flat, but provided with a slight convexity 50 which extends longitudinally of the base. With this construction it will be apparent that when the comb is secured in position by the clamp 43 and rivets 44, the comb base will be stressed. We have found that this tends to produce a louder and clearer tone than where the comb is secured flat against a fiat surface.

We also prefer to position the clamp 43 in such a manner that the inner edge 51 thereof is spaced inwardly slightly away from the edge 52 of the mounting base. We have found that excellent results are obtained if the line of contact of the edge 51 of the clamp with the comb lies in a plane disposed at an angle of about 60 to the plane of the comb and passing through the edge formed by surfaces 42a and 52 of the mounting base 14a. The opposite edge 53 of the clamp 43 may be positioned slightly inwardly of the margin of the comb base and relatively greater latitude is permissible as to the location of this edge of the clamp.

In Fig. 7 we show a modification wherein the comb mounting surface, here indicated by 42b, is provided with a central plateau 54, which serves to warp or stress the base of the comb, as shown in the drawing, when the comb is secured to the mounting base 14b by the rivets 44 and clamp 43.

The height of the convexity 50 or plateau 54 above the remainder of the surfaces 42a and 42b respectively, need not be great, and can conveniently be of the order of .002 of an inch.

With any of the above-described constructions it will be apparent that the marginal side edges of the clamp will firmly engage and slightly bite into the material of the comb with the result that the comb is firmly clamped in place on the base.

Also, with the above-described construction, the comb 13 is tightly held substantially parallel to the plucking disk 12. The ends 41 of the vibrators 41 of the comb are turned or bent to project toward the disk into the paths of the plucking projections 22 on the disk. It will be apparent that the mounting base provides ample room for vibration of the vibrators of the comb. Also, with the construction outlined, the comb and the plucking projections of the disk are located between the sounding board and the outer surface of the disk, thereby affording protection to these parts.

Referring now to Figs. 8-10, it is one of the features of the invention that the mounting base is designed for the purpose of mounting a second music comb and to accomplish this the upper surface of the body 14 of the mounting base is provided with a central plateau 56 surrounded by a ledge 57 for the purpose of accommodating an adapter or riser, generally indicated by numeral 60. The adapter 60 consists of a body 61 formed with a depending marginal wall 62 to fit the ledge 57 on the mounting base. The member 61 provides an upper surface 61' to accommodate a second music comb, indicated by 13a, which is clamped thereto by means of a clamp 43. In this case rivets 63 extend through both combs and clamps and through the mounting base and the adapter, securing all the parts together. With this construction it will be apparent that the second comb is mounted above the plucking disk. The disk 12a, of course, is provided with plucking projections on both sides in order to actuate the two combs.

In order to change the gear ratio or drive for the plucking disk when two combs are utilized, the adapter 60 is provided with an extension 65 which is formed to provide bores 66 and 67. When the parts are assembled the bore 67 is in alignment with bore 29 in the mounting base and bore 66 is in alignment with a bore 68 in the mounting base. A shaft 60 which may carry a crank at its outer end (not shown) is provided and journalled in the bores 66 and 68. A pinion 71 is rotatably mounted on this shaft, being associated with a drive spring 73 of the type previously described. The pinion meshes with a gear 74 having a section which meshes with the teeth on the periphery of the plucking disk. A spacer sleeve 75 is provided between the boss 30 of the mounting base and the gear wheel 74.

It should be apparent from the above that a unique construction has been provided which is adaptable for the mounting of either one or two music combs and a rotatable plucking disk therefor. It will also be apparent that the construction is compact and readily lends itself to incorporation into an infinite variety of articles.

In Figs. 11, 12 and 13 we show alternate means for mounting the comb. In these figures numeral generally similar to the mounting base 11 previously described. This base is provided in one instance (Fig. 11) with a recessed under surface 81, the lateral margins 82 and 83 of which extend below or beyond the surface 84 of the mounting base. With this construction a music comb 13 may be secured against the lateral, relatively sharp-edged portions of the mounting base bordering the recess 81 by means of rivets 86. The rivets are mounted in such a manner that the base portion of the comb is deflected or bent inwardly slightly so that it is held in tension against the two regions 82 and 83.

Referring to Fig. 12, we show a form of mounting wherein the base is provided with a flat under surface 91 against which the comb is mounted. In this instance the comb, indicated by 92, has a base portion 93 provided with a longitudinally extending laterally arcuate section 94, the convex side of which is positioned against the surface 91. The comb is secured in place by means of the previously described clamp 43 and rivets 96. It will be apparent that this construction also places the base of the comb in tension.

Referring now to Fig. 13, the base 90a has a comb mounting surface 91a accommodating a comb constructed in a manner such that it serves as its own clamp. The comb includes vibrators 101 and a solid base portion 102. The base portion is formed to be laterally arcuate and, in mounting, the concave side of the base faces the surface 91a. The comb is secured by means of rivets 103 in such a manner that the base of the comb is slightly flattened and thereby held tightly in engagement with the surface 9 1a at each lateral margin of the comb base.

Each of the described methods of mounting the music comb results in a music box capable of giving loud, and clear tones.

Although the invention has been particularly shown and described, it is contemplated that various changes and modifications can be made without departing from the scope of the invention as set forth in the claims.
