1509299 Toy inertia wheel motors J R BECKER 15 Nov 1976 [24 Nov 1975] 48209/75 Heading A6S A toy inertia wheel motor for a toy vehicle includes a flywheel rotated by repeated manual actuation of a winding device against spring biass which returns the winding device to its initial position after each actuation disengageable gearing between the winding device and the flywheel disconnecting the winding device from the flywheel as it is returned each time to its initial position. The winding device may be a plunger pulled or pushed against spring biass, but as shown comprises a pull cord 15, Fig. 1 unwound from a shaft 14 against the biass of a coil spring 17. A gear 13 fast on the shaft 14 drives through gearing 12, 11, 7 to a shaft 6 forming the rear axle of a toy car, &c. and carrving a flywheel 5. Gears 11, 12 are carried on a shaft 9 journalled in a slot (10), Fig. 2 (not shown) and gravity biassed to engage the gear 7. When the pull cord 15 is released and rewound onto the shaft 14 by the spring 17, the slot (10) allows the shaft 9 to move and disengage the gears 11, 7. The flywheel 5 accordingly continues to rotate, and the pull cord 15 can be actuated repeatedly. The inertia wheel motor of Fig. 1 is mounted directly in a motor oar body 2. In an alternative construction. Fig. 3, an inertia motor having a flywheel, &c. 23, &c. is carried in a frame 20, 22 for attachment by screws to a toy vehicle body. A relatively thin gear 28 on an intermediate floating shaft 27 meshes a gear 25 fast with the flywheel. A gear 29 on the intermediate shaft 27 meshes a relatively thin gear 30 when a cord 35 is pulled to unwind it from a shaft 31 against the biass of a spring 33, and disengages from the gear 30 when the cord is released.
