claims'. (ci. 46-243) This invention relates to a toy ball kand a switch therefor, and more particularlyY relates to a ball which contains therein motive means to effect rolling movement of the 'ball across a surface when the ball is disposed on thesurface at a selected attitude.

kThe object of this invention is lto provide a toy ball which is highly amusing and fascinating.

Another object of this invention is to provide a toy ball which carries its own motive power and which may be caused to either roll across a substantially at surface or to move across the surface of a body of water.

A further object of this invention is to. provide a toy ball which carries its own motive power and which has a novel gravity-actuated control which initiates operation of the motive power whenthe -ball is in one position and which shuts off the motive power when the ball is in another position.

Further objects and advantages of this invention will become- `apparent as thelfollowing description proceeds and the features of novelty which characterize this invention will be pointed out with particularity in the claims annexed to and vforming part of this specification.

A preferred embodiment of the invention is shown in the accompanying drawings, in which:

Referring now tothe drawings, there is shown a hollow tOyballgener-ally indicated at 10, which ball is formed of a pair of substantially hemi-

spherical shell portions

12 and 14. As best seen in Figure 5, the heini-spherical shell portion 12 is provided with a peripheral tongue 15 on the circular edge thereof, and the hemi-spherical shell portion 14 is .provided with a peripheral groove 16 on the circular-edge thereof. The tongue 15 and groove 16 are adapted for mating cooperation. A gasket 17 of rubber, or like material, is provided between the adjacent. mating surfaces of the tongue 15 and groove 16 for'sealing the hollow ball. The gasket material 17 is preferably'` deposited either on the tongue 15 or in the groove 16 lby spraying, painting, or the like, by using gasketmaterial in liquid formV which sets upon exposure toair.

The shell portion 14 is provided with a pair of diametrically disposed flanges 18 which extend outwardly of the 2,939,246 Patented June 7, 1960 circular edge of portion 14.and which are bored and splined at 20 'for reasons thatwill become apparent hereinafter. The shell portion 14 is also provided with a pair of elongated diametrically disposed latch members 22 formed on the inside thereofand being shaped to define hooks, or enlargements, 24 onthe extended ends thereof. The latch members 22 extend from shell portion 14 beyond the circular edge-thereof and are ladapted for selectively releasable cooperation with latch-receiving recesses 26 formed on the inner side of shell portion 12 for securing the pair of

shell portions

12 and 14 together. The latch members 22 are somewhat resilient, thereby providing selectively releasable latch means. It will be seen that the latch members 22 are offset approximately 90 from anges 18. I

Mounted in the splined ilanges 18are the splined ends of an elongated drive shaft 28, the splines of the shaft 28 cooperating with said drive shaft engaging means on ball 10 to elfect a driving connection therebetween. Mounted on the drive sha-ft 28 are motive means for causing the ball to rotate. -Said motive means include frame means, generally indicated at 30, provided with bearings 31 through which the drive shaft 28 extends.r The frame means 30 carries thereon a battery-driven electric motor 32, of a type which is readily available and has been used to provide a drive yfor battery-operated devices. The motor 32 is offset from shaft 28 and has a. drive shaft 34 extending therefrom and carries thereon a gear 36. A gear-reducing arrangement is provided byv means of sprocket 38, meshed with gear 36, and gear 40, which rotate together on a shaft 41 rotatably mounted on the frame means 30, and the gear 40 drives a sprocket 42, which is keyed, or otherwise appropriately drivingly connected, to the drive shaft 28. The gear-reducing means, comprising gearsk and

sprockets

36, 38, 40 and 42, provides means for transmitting torque from the motor 32 -to the drive shaft 28.

Also secured to the. frame means 30, by any appropriate means, and offset from the axis of shaft 28, are battery-receiving meansgenerally indicated at 44. The frame means 30 together with' battery-receiver 44 constitute wha-t may be referred to as unitary frame means forcarrying the motor 32 and the battery for energizing the motor. The battery-receiving means 44 is appropriately shaped to receive a battery 45. One end wall 44a of the battery-receiving means 44 is formed of an electrically non-conducting material and is connected to means 44 by tabs 44b. The end wall 44a is provided with a contact member 46 having a detented yarm 47 extending therefrom. The contact 46 electrically connects to the batterys center tap and is appropriately insulated by wall 44a from the remainder of batteryreceiving means 44 which electrically connects to the batterys easing. An appropriate latch member 48 is provided, p ivotally connected at one end to the batteryreceiving means 44, and provided with a detent 49', for releasably securing battery 45 in position.

Mounted on the insulator end 44a of batteryreceiving means 44 is a manual-ly operable switch member 50, pivoted at 52, and carrying a detented contact member 54, adapted for cooperation with detented arm 47, and for selectively opening or closing the energizing circuit for motor 32. An electrical lead 56 connects contact member 54 to the battery-driven motor 32, and extending from motor 32 is a second electrical lead 58 which leads to a gravity-actuated switch, generally indicated at 59.

The gravity-operated control means is clearly illustrated in Figure 4 and includes a tubular lbody 60, serving as a first contact, andA electrically connected to the batterys casing through member 44 to which body 60 is brazed. A second contact 62 is disposed axially within tubular body 60 and is insulated therefrom by the annular insulator 64. The contact 62 serves to close olf one end of the tubular body 60. Mounted within the tubul-ar body 60 is an elongated contact pin 66, one end of which is adapted to engage contact 62, and the side of which is adapted to engage the inner side of tubular body 60, to thereby complete the circuit between contact 62 and body 60. When the switch of Figure 4 is in an inverted position, gravity will cause the conductor pin 66 to separate from contact 62, thereby opening the switch. The body 60 carries a retainer member 68 which is disposed across the path of travel of the elongated pin 66 and prevents loss thereof when the gravity switch is inverted. The transverse portion of retainer 68 is spaced from contact 62 a distance greater than the length of conductor 66, and is spaced from the open end of body 60 a distance less than the length of conductor 66.

The gravity switch 59 is so mounted on the frame means 36, or on the battery-receiving member 44, carried thereby, that when the drive shaft 28 is disposed horizontally, the gravity switch 59 is closed and if the manually-controlled switch 50 is also closed the circuit through the electric motor is completed. This will cause torque from the lmotor 32 to be transmitted to the drive shaft 28. Since the center of gravity of the unitary frame means 311-44, motor 32, and battery 45 carried thereby, is oifset from the axis of the drive shaft 28, said center of gravity will tend to remain below the axis of drive shaft 28 when drive shaft 28 is disposed substantially horizontally, and the torque transmitted from motor 32 will effect rotation of the drive shaft 28 about its axis together with the ball connected thereto. This will cause the ball to roll over a surface onto which the ball is disposed.

lf placed on a body of water, say in a tub or the like, the .ball will travel across the surface thereof. The mass of the lball and the drive means therefor is such that the entire mechanism will float. The gasket means 17 prevents any leakage through the body of the ball.

When the ball is completely upended from the position shown in KFigure 2, then the conductor pin 66 will tend to lfall away from the contact 22, thereby opening the gravity switch and shutting otf themotor 32. This permits one to selectively ax some sort of designation, such as a color spot, on the ou-tside of ball adjacent the lower end of the drive shaft 28 (as seen in Figure 2) and, by mounting the ball 10 lon a base, or holding means, so that the `designation is facing Iupwardly, the gravity switch 59 is maintained in its open condition.

The shell portions `12 and 14 are preferably formed of a thermosetting transparent plastic, so that the interior mechanism may be viewed, thereby further enhancing the fascination of the toy. Alternatively, the shell portions may be opaque, colored, or otherwise decorated as desired. rllhe flexibility of the

shell portions

12 and 14 permit of manual distortion thereof to effect their securement together or separation thereof, and also permits of selective connection of drive shaft 28 with the drive shaft `engaging means as herein provided.

While there has been shown and' described a particular embodiment of this invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention and, therefore, it is intended in t-he appended claims to cover all such changes and modifications as fall within the true spirit and Iscope of the invention.
