MUS I CAL TOY Filed Nov. 9, 1929 Patented Oct. 7, 1930 UNITED STATES PATENT OFFICE HOWARD N. BARNUM, or CLEVELAND, OHIO MUSICAL TOY Application filed November 9,1929. Serial no. 405,861. I

dicated at 9, and has its outer I end attached One of the objects which I have in view is the provision of a toy representation of a person playing a Xylophone or other musical instrument, the mechanism being ar- 5, ranged and actuated so that a predetermined sequence of musical notes may be struck and thus, if desired, a selected tune may be played.

Another object which I have in view is 10, the provision of means whereby within reasonable limits any selected one of a plurality of tunes may be played by the toy.

'For this and other purposes I have invented a toy, an embodiment'of whose principles are hereinafter described.

In the accompanying drawings wherein I have illustrated a practical embodiment of the principles of my invention in a xylophone toy, Fig. 1 is a side elevation-of the toy. I

Fig. 2 is a plan viewof the same, certain of the parts being shown in dotted linefor the sake of clearness.

Fig. 3 is a plan view of the operating gear train looking downwardly from the line 3-3 in Fig. 1.

Fig. 4 is a detail showing the thrust rod and the cam track.

Fig. 5 is a plan view showing one of the tune cam plates.

Referring to the drawings, 1 represents four vertical legs which support an open table frame '2, which frame may be formed by bending up a strip of suitable material into rectangular form. v

'3 represents a series of musical bars grad uated in length to the musical scale and which are supported transversely on said table and held against displacement as by the bent tongues 4 extending from the table and engaging holes in the bars.

The legs 1 may be formed by bending the end portion of a pair of lengths of wire whose intermediate portions 5 may be in the form of horizontally disposed Vs which may be attached to the base plate 6 of a housing which also comprises the vertical posts 7 and the platform 8. I v y I The driving mechanism of thetoy is preferably a spring motor, whose spring is inswing on a hori'z 'ontal axis.

to one" oftheposts 7, asatIO. The central shaft 11 of the motor" extends upwardly through the platform 8 and a gear 12 is mounted on said shaft below said platform.

The gear 12 meshes with a pinion 13 mounted on the shaft 14 which is journaled between the base (Sand the platform 8. vThe shaft 14 has mounted thereon a gear 15 which, meshes with a pinion 16 mounted one shaft 17 whose ends are also journaled in the base 6 and the platform 8. I A i The shaft- 17 hasfixed hereon a spiral cam track :18 upon which track stepped the lower end' of a thrust rod 19, The thrust rod is longitudinally slidable in avertically disposed tubular sleeve 20 whichextends down through a bearing hole in the platform segmental gear 23 which is mounted on a shaft journaled in a bearing in the platform. 24 represents a representation of a human figure which maybe stamped or otherwise formed of metal and has its lower portion I secured, as by soldering, to the side of the sleeve 20 above the gear 23. 25 represents an arm of the'figure which is pivotally connected to the figure proper, as at 26, so as to endof the arm; 25'isahammer 27 which is caused toJstrike the musical bars 3. The upper end of the thrust rod 19 is pivotally connected to the arm 26 intermediate of the ends of the arm, so that the arm will be raised and lowered by the travel of the thrust rod relative to the spiral cam track. Thus the hammer is raised as the lower end of the Fixed to the free Band has its'f lower end supported from below by thehorizontal portion of a'bracketio thrust rod climbs the cam track and the hamn mer is dropped to strike a blow asthe rod passes ofi the upper end of the cam track and drops on to the lower end of the latter.

The shaft 11 above the platform 8tis shoulend (if the shaft is threaded,"

de d t Supp a ash 28. n tl fluppe 29 represents the tune cam plate which is provided with a central opening to permit it to be slid down over the end of the shaft 11 and rested upon the washer 28.

30 represents the binding nut which is screwed on to the end of the shaft against the cam plate 29 to clamp the cam plate rigidly to the shaft. The nut 30 is provided with radial handles 31 so that it may be used as a winding key for the motor spring.

The segmental gear 23 is provided witha post 32, which post is held in continuous contact with theperimetral edge of the cam plate 29, as by a spring 33 connecting the foot of the figure with one of the legs 1. 7

It is obvious that as the cam plate 29 :is rotated by the motor, the segmental gear 23 will be rotated in either direction in accordance with the perimetral contour of the cam plate, thus swinging the figure 24 on a vertical axis and thus directing the blows of the hammer 27 against various of the musical bars 3.

Thus by providing a cam plate 29 with the proper perimetral contour the figure maybe causedto strike any desired sequence of notes, thus, if desired, playing. a selected tune.

The cam plate 29, illustrated in the drawing, has the perimetral contour to cause the figure to play the tune Yankee Doodle on the Xylophone. i

. The cam plates are interchangeable so that a plurality of plates may be furnished with the toy, each having a contour-which will cause the figure to play a giventun'e, so that by installing the proper cam plate-on the toy any desired tune in the repertoire may be played.

A suitable governor mechanism should be provided for the motor. 7 Thus, I have shown the shaft 17 provided with the gear 34l meshing with the pinion 35 on ashaft 36. The shaft 36 is also provided with the gear 37' which meshes with a pinion 38 on a shaft 39 which carries 7 the eccentrically mounted weight 40. a
