TOY WHTRLIGIG.

Application filed June '15, 1927. Serial No. 198,888.

the device, once set in motion, will continue in motion time.

Another object is the provision of a novel bearing between the pedestal supporting the device and the moving part of the device.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts inthedrawings.

Referring briefly to the draw1ngs,'F1g. 1 is an elevational view of the device. I Fig. 2 is a plan view of the device.

Fig. 3 is an enlarged central sectional view through the upper neck of the sup porting pedestal.

Referring in detail to the drawings, the numeral 10 indicates the supporting pedestal of the device, narrowing upwardly into a neck 11. A peg 12, supported dependingly from a drum-shaped anchor 12, is supported looselyrin the top of the neck 11.

for a relatively long period of Spaced-apart angular rods 14 extend downward and outward from the lower part of the anchor 13,, and have their lower ends imbedded in an annular weight 15, which they support, this weight providing a balance for the device in action.

Otherangular rods 16 extend upwardand outward from the anchor 13, and support in pivotal suspension, miniature airplane models 17.

The upper end of thezneck 11 of the pedestal is cupped out to provide a recess. Onopposite sides of the recess horizontal ears18 are provided over the recess, in.diametrically opposed relation. Vertical pins 19 are mounted rigidly between the ears Y18 and the floor of the recess,'and each pin has a small ball 20 rotatably mounted thereon.

A larger ball 21, having an equatorial groove 22 thereon, is loosely I mounted between the balls 20, the latter registering in the groove 22' and thereby preventing the ball 21 from any movement excepting rotation in a horizontal plane. A conical cutout portion is provided in the ball 21 to seat the peg 12.

hen used as a toy, the device may be i used as shown or it may be provided with mechanical actuating means such as spring motors for the propellers 1n the airplanes.

I Once the device has been set in motion, the

entire portion supported by the peg 12 will rotate about its center, and at the same time it will have a wobbling motion caused by the balance weight 15. The planes will thus rise and dip rhythmically while rotating about the pedestal. To accommodate the sidewise motion of the peg, the cut-out 23 is madeof a slightly greater angle of taper 7 than that of the peg 12.

The bearing shown in Fig. 3 greatly diminishes the friction between the moving and stationary. parts of the device, and therefore the planes willcontinue'to revolve for a relatively long time. First, the peg is free to revolve in the cut-out'23; the

ball 21 is free to revolve between the balls 20 on the base of the recess; and the balls 20 are free to, revolve upon their shafts 19. lVhen used as an amusement device to carry passengers, actuating means of various kinds may be employed, such as individually actuatedpropellers on the planes, or

means for giving the moving part one or more rapid turns and then releasing it to rotate by its momentum until brought. to rest. 1 I

I The device may also be used for various commercial purposes such as for advertising and on aeroplane landing devices.

What is claimedis as follows:

1. A device of the class described comporting means.

porting meansextending from said anchor, balls rotatably supported in said recess and and mlniature models attached to said supregistering in said groove, said first-named 10 ball having a cut-out portion, a peg loosely 2. A device of the class described comsupported in said cut-out portion, and outprising a pedestal, said pedestal having a wardlyextending supports carried by said recess in its upper end, a ball loosely peg. 7 a mounted in said recess, a circumferential In testimony whereof I affix my signature. horizontal groove in said ball, additional ARTUR DRAUDEN.
