1340823 Controlling clutches; toothed gearing TOMY KOGYO CO Ltd 10 Jan 1972 1043/72 Headings F2L and F2Q [Also in Divisions A5-A6 and H1] A toy vehicle (see Divisions A5-A6) has a motor which either drives a working mechanism, e.g. a crane, on the vehicle, or the rear road wheels. The motor 20 is battery powered under the control of a three-button switch (see Division H1) for forward drive, stop, or reverse. In one direction of rotation, the motor 20, Figs. 6a, 6b drives through a step-down gear train 61, 62, 66, 68, 72, 76 to a "floating" gear-wheel 94 on a shaft having one end journalled in a casing 18 and the other slidable in a slot (98), Fig. 9 (not shown). Rotation of the gear 76 in the direction of the arrow moves the "floating" gear-wheel to mesh a gear 74, and thus drive through gears 106, 108 110, 112, 102, 84 to a shaft 82 having an accentric pin 88 sliding in a slot in a segmental rack 80. As the shaft 82 rotates, the rack 80 pivots back-and-forth, thus oscillating a meshing gear 14 connected to the jib of the crane, &c. In the other direction of rotation of the motor 20, the reversal of motion of the gear 76 from the clockwise indicated in Fig. 6b to the anti-clockwise indicated in Fig. 8 throws the "floating" gear 94 out of mesh with the gear 74, so that the crane, &c. is no longer raised, &c., and instead into mesh with a gear 128 fast with the axle 130 driving the road wheels 126.
