23 Claims. 1

My invention relates to inexpensive musical toys which are easily operable to produce the tones of several different sound-producing instruments.

An overall object of my invention is to provide a sound-producing toy having a strong appeal to a child because of its attractive appearance, its simulation of a real musical instrument, its ease of manipulation, and its variety of sounds.

A further object of my invention is to provide a device of a type described which generally resembles a trombone in appearance, with sliding nested tubes and bell, but which is provided with means enabling tones to be readily produced without embouchure so that the device can be played or sounded by any child having no particular talent or training.

In the preferred embodiments herein described, the toy, while trombone-like in appearance, can be selectively used to create sounds such as come from a kazoo, or such as come from a whistle. A special advantage is obtained by providing a slide by which the pitch of the whistle-tone can be varied. In the toy device, the slide also gives free play to the imagination of the child-player. I

A further advantage of my construction resides in the fact that the device may be readily changed to play solely as a whistle or as a kazoo. In general, parts of the device are manually relatively movable to definite positions where there can be no interference in sounds. In one general form of my invention, the parts are separable, with one part being adapted for use as a whistle, and another part capable of being played as a kazoo.

Other objects, advantages, features, and innovations of my invention, in addition to the foregoing, will be discernible from the following description and attached drawings of difierent embodiments. In the drawings, which are not to scale and should be considered in conjunction with the description:

Fig. 13 is an elevational view of an outer tubular member for the embodiment of the invention shown in Figs. 6-11; and

Fig. 14 is a longitudinal sectional view of a part of still another form embodying the teachings of my invention.

The embodiments shown in Figures 1 and 2 has the appearance of a, miniature trombone, and comprises a comparatively stationary piece or frame and a slidable tuning means which hereinafter is referred to as a. slide, slide member, or by some similar expression. The stationary piece and slide are indicated in their entireties in the drawings by the reference numerals I and 2, respectively.

The stationary piece or frame I comprises a short tube-means 3 and a curved bell-member 4 joined by a cross-bar 5.

The tube-means 3 is hollow for providing an air-column, and comprises a hollow member in the form of a straight air-column tube 6 terminating in a flared mouthpiece I. Near the mouthpiece I, the tube-means 3 is provided with a kazoo-part comprising an oblong hole 8 defined by a raised flange 9, the inside of which is stepped to form a seat It for a thin vibratile member I I held in place by a Washer I2 and a ring I3 pressed into the recessed part of the flange 9. The membrane II may be of tissue paper or other suitable material, and may be pasted or otherwise secured to the washer I2. A hole I4, near and smaller than the hole 8, may be provided in the tube 6 for adequate venting of air when the toy is sounded as a kazoo.

The tube-means 3 further comprises a second hollow member in the form of a round conventional-type whistle I5 which snugly fits the inside of the tube 6 at it mouthpiece end. The whistle is readily slidable by a child into and out of the tube 6. An inwardly extending protuberance or stop It of the tube 6 determines the inserted position of the whistle I5. Preferably, the slidably fitting portions of the tube 6 and whistle I5 are finished for smooth coaction.

The whistle i5, Figs. 1 and 2, is of a short length, comprising a straight tube having a solid surface except for a triangular exhaust or whistle opening IT. A tapered air-directing plug or wedge 18, inside the whistle, slopes to the opening 11 as is customary in such whistles. The outward end of the whistle, beyond the opening Il constitutes a mouthpiece It for it.

The stop it has the important function of positioning the whistle in the tube 6 so that the kazoo-hole 8 and vent hole is are completely covered. This means that the circumferential portion of the wall of the whistle, next to these holes, should be solid.

The whistle should also be of such length that its whistle-opening l'l will be sufhciently clear of the wall of the mouthpiece l for ireely sounding the whistle while it i" in the tube If the openin I1 is too close to the wall of the mouthpiece 1, the wall apparently interferes with the movement of the air passing through the opening. Such interference or blocking makes the whistle harder to blow for producing a whietle-tone, and muilles any tone which produced. in order to minimize this difficulty and to reduce the length of the part of the whistle which extends outwardly from the mouthpiece l, I consider it desirable, in modifications of the type de 'cribed, to sharply, rather than gradually, flare the mouthpiece.

The curved bell-member 4 comprises a relatively straight portion 26 and a curved portion 2|, both of which are hollow. The latter is bent to return in the direction of the portion and slowly increases in diameter, finally flaring into a bell 22.

The slide 2 comprises a U-shaped tube having parallel legs 23 and 24 joined by a curved basepart 25. The legs are also joined by an external manipulator bar 26. The tube e or the tube-means 3, and the tube 2% of the bell-member 4 slida-bly fit into the legs 23 and 24, respectively, of the slide. The inside of the leg 23 is provided with a barrier or closure 2'! which closes the associated end of the air-column that extends from the mouthpiece, and also determines how far the slide 2 can be moved on the tube-means 3, toward the mouthpiece or the kazoo-hole 8, for tuning or varying the air-column.

The method or playing of the device described is obvious. For example, with the whistle removed, the instrument is in the nature of a lzazoo and may be sounded in the same manner, the mouthpiece 'l functioning as such. When the whistle is inserted until reaches the stop is, the kazoo-hole 8 is covered so that vibrating air cannot reach the membrane 9 i. The stop I6 also fixes the position of the whistle-opening ll so that it is not obstructed by the mouthpiece 1. Blowing the whistle therefore causes the instrument to produce a whistle-tone, the pitch of which can be varied by moving the slide 2 with respect to the stationary piece or frame i that includes the tube-means 3. The whistle i5 is, of course, also playable by itself but only at its natural pitch.

In order to give the toy-device a greater degree of variety, the whistle can be modified to include tone-holes of its own, and such a modification is shown in Figs. i and 5 in which the toydevice is provided with a stationary part of frame l a and a slide 211, along the lines of the modification shown in Figs. 1 and 2. However, the whistle 32 is longer that the corresponding whistle I5, and is provided with a plurality of spaced pitch-

holes

33, 34 and 35. The stop 36, in a tube 37 of the stationary part la, positions the whistle 32 so that its pitch-holes are covered by the wall of the tube 31 while the kazoo-hole 38 is covered by the wall of the whistle. When inside the tube 31, the whistle can be caused to sound in various pitches by moving the slide 2a so that the plug or transverse closing wall or barrier 39 varies the length of the air-column extending thereto. When outside the tube 31, the whistle can be sounded in different pitches in the usual manner by covering or uncovering the

holes

33, 3t and 35 in different combinations.

of positioning means, such as the stop iii in Fig. 2 or in 5, causes the whistle to cover the hole of the kazoo-part, and also insures an unobstructed for air from the whistlecpening, such as il in Fig. 2 and the correspond-- rm opening in Fig. 5, so that the angular posin oi the whistle about its axis is unimportant in embodiments described.

For a device in which the air-column in a tubeeans, such as of Fi 2, would be too long for sound range desired, the expedient shown in mg. 3 may used. This comprises a piston rod Gd having an end attached to a support ll in a The other end of the piston rod, to-

ich slidably fits he inside of the asso- 6 and closes the air-column thereat.

embodiment shown in Figs. 1 and 2.

y be noted that in the embodiments in l, 2 and 3, the curved portion 2i v.ember extends farther to the left, that. is, outwardly away from the slide, than the flared mouthpiece 2. As a toy, the embodiments are much smaller than e usual t pic-a1 tromb '"ecognized as musical inst torrents of quality. Elowever, in a toy device built in accordance with the embodiments shown in Figs. 1, 2 and 3,

in order to have the bell-member clear the face or cheek of a child, the comparative reduction in length, is greater ratio than the reduction in Wldll'l'i, by width a distance in a direc tion substantially pe pendicular or lateral to the axes of the nested tubes. A lateral separation of about two inches between the mouthpiece i and the bell-znemher G is recommended for a toy device in which the bell-member extends outwardly beyond the mouthpiece about one and threefourths inches.

However, the feature shown in Figs. 4 and 5 may also be us for avoiding t e pressing of the bell-member c inst the cheelz. In this embodiment, the n red mouthpiece la is more nearly in lateral alignment with the extreme curved portion it of the bell-member 4a, than the corresponding parts of the embodiments of Figs. 1, 2 and 3.

While a manipulator bar 26 has been shown in Fig. l, as part of a slide, this bar can be omitted in a small toy--device since the base-part of the slide, such as base-part 25, is within easy reach of a child and can be grasped ior manipulating the slide. Such a modification, omitting a distinct manipulator bar, is shown, by way of example, in Figs. 4 and 5.

In the forms thus far described, each embodiment has one mouthpiece which is used in producing the whistle sound and a difiicrent mouthso which is used in producingthe lzazoo sound. In the forms hereinafter described, each embodiment has a single mouthpiece which is used in producing the different sound effects.

7 Referring to the embodiment shown in Figs. 6-13, the musical device, also resembling a trombone in appearance, comprises a stationary piece or frame 58 and a'slide The stationary piece 58 comprises a bell-member 52, a tube-means 53, and bars 54 and 54' joining the bell-member and tube-means.

The bell-member 52-is similar to those of the prior embodiments and comprises a straight tube and a bell 55' joined by a curved portion 56.

The tube-means 53 comprises a pair of concentric or nested generally cylindrical hollow members consisting of a relatively short outer tubular member 51 and a relatively long inner tubular member 58. The former snugly but slidably fits around an end portion of the latter, on which itcan be twisted or rotated to different angular positions without changing its relative longitudinal or axial position with respect to the latter. To keep this predetermined longitudinal arrangement, the longer tubular member 58 is provided with a radially outwardly projecting ring 58 against which an end-face 68 of the outer member 51 abuts.

Referring more particularly to Figs. 7 and 13, the outside of the outer tubular member 51 is further provided with a flat short outer wallsection 52, a flared mouthpiece 63 at one end of the wall-section 82 and a whistle-opening 64 at the other end. The outer tubular member 5'. also comprises an inner longitudinally-tapered cross-wall 85 which is coextensive with, but inwardly spaced from, the wall-section 82 to form a tapered open-ended whistle-passage 86 which is rectangular in cross-section, as shown in Fig. 9.

The inner cross-wall 85 has a relatively thinner wall-portion 51 and a thicker wall-portion 88, the former being toward the whistle-opening 84 and the latter nearer the mouthpiece 63. Accordingly, an angular recess 68 is formed in the inner cross-wal1 55, at the place Where the

inner wall portions

81 and 58 meet.

On the side opposite to the whistle-passage 55, the thicker wall-portion 68 has an inner flat face 58 which lies in a plane that includes, or i is just short of, the center axis of the outer tubular member 51. Accordingly, a passage 18 is formed in the outer tubular member 51, the passage being bounded by the face 89 of the thicker wall-portion 58, and the inside surface of the outer tubular member '51, facing the face 68.

The outer tubular member 51 also includes a small vent hole H and a kazoo-hole 12 having a vibratile member 13 therein, as in the previously described embodiments. These holes are in the side of the outer tubular member 51 which is diametrically opposite to the side which includes the whistle-opening 84. Except for the whistleopening 65, the vent hole 1| and the kazoo-hole 12, the cylindrical wall of the outer member 51 is solid or uninterrupted.

With more particular reference to Figs. 7 and 12, the inner tubular member 58 comprises a hollow cylindrical tube 14 having opposite endfaces and 15. In a longitudinal direction from the end-face 15, the wall of the tube 14 of the inner tubular member 58 is solid or uninterrupted to a point just past the outer positioning rin 58. Beyond that in a direction toward the end-face 1-5, the tube 14 has, successively spaced therealong, a small vent hole 16, a larger port-hole 11 and a recess-opening 18. Circumferentially, the recess-opening 18 is a semi-circle. Axially, the recess-opening 18 terminates at the end-face 15 of the inner tubular member 58.

This end-face 15' is in the form of a semi-circu lar segment having a. smaller radius than the tube 14. The end-face 15' is part of a stepped barrier 8| which constitutes an end-portion of the inner tubular member 58, and provides an outer recess 82 in the inner tubular member 58.

The port-hole 11 of the inner tubular member 58 is circumferentially less than a semi-circle and axially at least as long as the kazoo-hole 12 of the outer tubular member 51.

The slide 5| has

legs

83 and 84 joined by a bend 84. The end of the leg 83 has a piston or barrier 85.

In the assembled relation shown in Figs. '1 and 8, the outer tubular member 51 snugly, but rotatably, fits around the inner tubular member 58, with the end-face 68 of the former against the ring 58 of the latter. The lengths and arrangement of the

tubular members

51 and 58 of the tube-means 53 are such that the outer tubular member 51 extends to the left farther than the inner tubular member 58. The extending portion comprises the mouthpiece 63 and the thicker wall-portion 58 of the outer tubular member,

1 these

parts

83 and 53 extending to the left beyond the end-face 15' of the inner tubular member 58.

In the assembled relation, the slide 5| engages the stationary part 58, with the

legs

83 and 84 of the slide slidably riding in the

tubes

14 and 55 of the inner tubular member 58 and bellmember 52, respectively, of the stationary part 58. The short length of the toy permits the slide 5| to be manipulated with respect to stationary part 58, by grasping the bend 84 of the slide. Movement of the piston on the leg 83 provides a variable air column in the tubemeans 53 comprising the

tubular members

51 and 58.

When the

tubular members

51 and 58 are adjusted as shown in Fig. '7, the toy can be sounded only as a whistle. In this adjustment, the passage 18 in the outer tubular member 51 is blocked 015 by the barrier 8| of the inner tubular member 58. The holes 18 and 11 in the inner tubular member 58 are covered by an overlying solid wall of the outer tubular member 51. The vent hole "H and the kazoo-hole 12 in the outer tubular member '51 are closed by the underlying wall of the inner tubular member 58. Accordingly, with the tube-means 53 in the adjustment shown in Fig. 7, air from the mouthpiece 63 can pass only through the passage 66 and the whistle openin 84. The toy is a whistle in its sound effect, having a pitch which can be changed by movement of the slide 5| with respect to the stationary part 58.

The tube-means 53 can be adjusted to the arrangement indicated in Fig. 8, by twisting its outer tubular member 51 through on its inner tubular member 58. In this adjustment, although the same mouthpiece 83 is used, the toy can be sounded only as a kazoo.

In the adjustment shown in Fig. 8, the thin wall-portion 61 of the outer tubular member 51 lies in the recess 82 of the stepped barrier 8| at the end of the inner tubular member 58; and the barrier 8| of the inner tubular member '58 lies in the recess 88' of the outer tubular member 51. Hence, in this adjustment, the

tubular members

51 and 58 cooperate to prevent the whistle sound while permitting a kazoo-sound. The whistle sound is prevented because the whistle-opening 54 and the passage 65 in the outer tubular member 51 are closed by the under--v lying solid wall of the inner tubular member 58 and its barrier 8|. The kazoo operation is possible because the port-hole l1 and the vent hole 1.6 in the inner tubular member 58 are in registry with the kazoo-hole 12v and the vent hole II, respectively, in the outer tubular member 58. Also, the passage in the outer tubular member 51- is in line, axially, with the recess-opening 78 of the inner tubular member 58. Accordingly, air from the mouthpiece 53 can vent only through the registered vent holes H and T6, with the vibrations of the air sounding the vibratile member 13 in the kazoo-hole 12. The slide 5| can still be manipulated to give free play to the imagination of the child playing with the toy.

Fig. 14 shows an embodiment alon the lines of that of Figs. 6-13, but simplified somewhat. It comprises a tube-means having an outer hollow member 90 of simplified form. The outer tubular member 90 consists only of a tube with l a mouthpiece 9|, a whistle-opening 92, a kazoostructure 93, and a vent hole 94. The tube means also comprises an inner hollow member 95 which nests inside the outer tubular member 90, and is provided with a vent hole 96, a kazoo port-hole 91 and a recess-opening 98. The end of the inner tubular member 95 has a solid wall section 99 which substantially fills the inside of the outer member 90, except for a narrow tapered openended passage I00. Obviously, this passage I09 is common for both the whistle and kazoo a iustments.

The embodiment of Fig. 14 operates in a manner similar to that of Figs, 6-13. In the adjustment shown in Fig. 14, the device will sound only as a whistle. The kazoo-structure 93 and the vent hole 94 of the outer member 90 are closed by the underlying solid wall of the inner member 95. Also, the port-hole 91 is closed by the overlying wall of the outer member 90. Accordingly, air from the passage I00 can pass only through the whistle-opening 92.

By turnin the outer member 90 through 180 on the inner member 95, the whistle-opening 92 will be closed by the solid wall of the inner member 95; and the port-hole 91 in the inner member 95 will be in registry with the kazoo-structure 93 of the outer member 90; and the vent holes 94 and 96 will also be in registry. In this adjustment, the device will sound only as a kazoo.

-It is to be noted that in the embodiment of Figs. 6-13, :3, common mouthpiece 63 and two

passages

66 and 16 are provided for playing the toy in any desired manner. In the embodiment of Fig. 14, a common mouthpiece 9| and a common passage I00 are used for playing the toy in any desired manner. In the embodiments of Figs. 1-5, the whistle-opening and kazoo-hole are in separate parts of the toy-device. In the remaining embodiments, the whistle-opening and the kazoo-hole are in the same part. In any case, the sound effect produced by the toy depends on the angular relation of two relatively nested inner and outer tubular members of a tube-means. However, in all embodiments, the slide is necessary for changing the pitch of the tone when the nested members are so related as to produce a whistle sound.

Fig. 14 also shows a modified form of positioning means comprising a bayonet joint arrangement comprising a circumferential slot llll in the outer member 90, preferably of 180 angular extent, and a pin H12 in the inner member 95, riding in the slot Illl. A smaller longitudinal 8 slot I03 may be provided, if desired, for permitting the members 99 and to be easily separated.

While I have described my invention in various forms, it is obvious that its teachings have wider application and can be embodied in forms other than those shown and described.
