-GYRATORY ran TOY.

Application :filediDe'cember 15,1935. Seria1 i No. 75,529.

This invention is for an improvement in mechanical toys, and particularly toys of thetype wherein a pan or track element is progressively tilted to impart-whatmay be termed a .gyratory movement thereto.

According to the present invention it proposed to provide a novel mechanical movement for imparting the desired eprogressive tilting motion to thepan or track element, and to provide a structure which can beimore cheaply :and easily assembled than toys of this-type heretofore made.

-It is also proposed to provide -a novel track for a toy of-this -ki-nd. V

The inventionmay be readily understood by reference to the accompanying drawings, wherein Figure 1 is atop plan view of apreferred for-m of toy= embodyingthe present invention; 7

liigure 2 is a horizontal section on the line IZ['II[ o-f lFigure 3; v

Figure 3 is aside elevation of the toy, showing the track pan in section;

iFigure 15 isa view similar to :Figure 3 showing the pan tilted-in the opposite direction from its inclination in'Figure 1;

"Figure 5 is a vertical :section on line V'-V of Figure 4;

Figure 6 is a detail view ona larger scale of the .gyrating post {and its connection with the pan; and

Figure 7 is a view similar-t Figure ti showing a slightly -modified construction.

In the drawings, 5 designates a suitable 'base, 6 is a substantially inverted U-shaped supporting frame secured on .the -base, and 7 designates-the-r'gyratory track pan. The track 7 preferably has a centralrdepre'ssio-n '8, a substantially fiat portion 9 around the center, a dished track portion 10, and a pcripheral flange 11. In the track portion 10 there is preferably formed a spiral groove r 12 having the innermost portion of its inner convolution connected with the outermost portion of the outer convolution by a crossover groove or track portion 12, which extends across the convolutions in a somewhat involute curve.

With an arrangement such as this, a gravity propelled object, such for instance as the miniature representation of an automobile, designated A in Figure 1, may be caused to travel around the several convolutions of track and back to the starting point when the pan is rocked intheproper manner. The wheels at one [side of the track only need ride in the ,groove to be guided thereby.

Lhaveillustrated this preferred form of traclg but it-will be obvious that any suitable arrangement may be substituted and the shape of the pan varied to obtain such movement of the car as may be desirable.

In order to impart a gyratory orprogressive tilting motion to the pan, and to supportthe pan, a button 13 may be riveted to the central portionof the pan, this button passing loosely through the top part of the supporting bracket 6. This button looselyanounts the pan on the support 6.

Below the top of the bracket "6 and. hearing against the bottom of theflbracket, is the cross bar 14 of a spring motor frame having the usual gear train adapted to drive a post or shaft 15. At 16 is a U"- shaped piece which formspart of the frame of the-motor. The m'otormay be wound bymeans of a key 17 which passes through the pan. The motor frame is rigidlysecured to lthe pan, by rivets 18 passing through the cross bar 14, spacers being employed at 19.

Set in the base 5 directly belowthe centeno fthe pan, is a cylinder 20 into an eccentric point of which oneend of the motor shaft lois projected, and with respect to which the shaft is fixed. The cylinder, however, is free-to rotate in the "base, and constitutes one form of an eccentric terminal for the motor shaft. 1

In the operation of the toy, the motor, in unwinding,rotates the shaft which in turn rotates the cylinder to which it'is eocentri'cal-ly secured The rotation of the cylinder 20, which is necessarily always inel-inedyout of azvertical position, causes the pan, which is non-rotatable, to be progressively tilted or gyrated. As the gravity propelled object will necessarily seek the lowest point on the pan, it will progressive- 1y move around the pan, being guided of course, by such tracks as are formed there'- on.

The mechanism for gyrating the pan is of a nature that permits easy and rapid assembly of the toy and materially cheapens the construction thereof. The structure is also one that permits of the disposition of the operating mechanism entirely under the pan and permits it to be secured thereto. No other supporting structure is necessary, except the small bracket 6.

Since the cylinder 20 has a fairly close fit in the base, it insures of an even motion being imparted to the pan and holds the pan against rocking except in the intended fashion.

The supporting arch 6 may have a lateral extension 21 thereon through which the shank of key 17 passes to limit the rocking movement of the motor frame and relieve the eccentric terminal or cylinder 20 of some of the lateral thrust.

In i igure 7 I have shown a simplified arrangement wherein the only difference is in the eccentric terminal on the motor shaft. In this construction 23 is the base, 24 the bracket, 25 the pan, 26 the center bearing button for the pan, 2? the motor frame, 28 the motor driven shaft and 29 a gear wheel that is on the shaft and forms a part of the gear train for the motor.

On the gear wheel 29 is an eccentric pin 30 that projects downwardly into a small hole 31 in the base directly below the bearing button 26. In its operation, pin 30 forms an eccentric terminal for shaft 28 and serves to impart a progressive tilting motion to the motor and pan when the motor operates, it being the full equivalent of the cylinder 20.

IVhile I have shown a preferred form of the invention, it will be apparent that various changes and modifications may be made thereon within the contemplation of the invention and under the scope of the appended claims.

I claim:

1.. A toy including a track structure, a motor secured thereto, a shaft rotatably connected with the motor, a base, and an eccentric terminal on said shaft guided in the base.

2. A toy including a base, a bracket on the base, a track member mounted on the bracket and free to gyrate thereon, a motor below the track structure, a shaft driven by the motor connected with but rotatable with respect to the track structure, and an eccentric terminal on said shaft guided in the base.

3. A toy including a base, a bracket on the base, a track member mounted on the bracket and free to gyrate thereon, a motor secured to the track structure, a shaft driven by the motor having one end thereof rotatably received in a bearing on the track structure and having an eccentric terminal at its other end, said eccentric terminal being guided in the base.

4. A toy including a base, a bracket on the base, track member supported on the bracket, a button on the track member pass ing through the bracket and providing a gyratory support for the track member, a motor secured to the track structure having a driven shaft whose upper end has a hearing in the said button, the lower end of said shaft having an eccentric terminal secured thereto, the said eccentric terminal being guided in the base.

5. A toy including a base, a support thereon, and a track member mounted for gyratory movement on the support, a motor secured to the track member, a shaft driven by the motor having a bearing in the track member, a rotatable cylinder in the base below the motor, said cylinder being eccentrically fixed to the lower end of said shaft.

6. A toy including a base, a support on the base, a pan on the support having a cen tral gyratory connection thereto, a motor secured to the pan, a shaft driven by the motor having a bearing in said central connection, and a cylinder in the base centrally disposed beneath the said central connection, said cylinder being eccentrically fixed on the lower end of said shaft.

7 A mechanical toy including a base, a progressively tiltable pan supported above the base, and means for tilting the pan including a motor secured to the underside thereof and a shaft operated by the motor, said shaft having an eccentric terminal guided in the base.

8. A mechanical toy including a pan, a base, a support on the base for the pan, and a motor carried by and secured to the under surface of the pan, and means driven by the motor for imparting a progressive tilting motion to the toy.

In testimony whereof I have hereunto set my hand.
