1459119 Toy vehicles CONSOLIDATED FOODS CORP 6 Dec 1974 [21 Feb 1974] 52822/74 Heading A6S [Also in Division H2] A toy vehicle, e.g. a diesel locomotive (10), Fig. 1, not shown) has a wheeled power truck 22 in the form of an upright hollow, housing 30 enclosing a motor, a motor shaft 71 projecting laterally from the housing 30 and being connected, e.g. by gearing 100 to running gear (24, Fig. 1, not shown) beneath the housing 30. The truck 22 supports via a gimbal mounting a hollow body (11, Fig. 11, not shown) injection moulded from plastics. The housing 30 may be die-cast of heavy material and has transverse slots 36-38 on the underside for receipt of axles 86-88 carrying wheels 80, 80a- 82, 82a, an axle retainer 90, e.g. moulded of resilient plastics, being snap-fitted to the base of the housing 30 via catches 92, 93 on the retainer 90 and upturned lips 34, 35 on the housing 30. Motor & Drive: The housing 30 is hollowed from one side at 53 to accommodate a rotor 70, e.g. of pancake type, on the shaft 71 and arcuate magnets 72, 73. A plate 75 detachably secured to the housing 30, e.g. by threaded members 76 completes the enclosure of the rotor 70. The plate 75 also carries brush holders 78 for the motor. The shaft 71 is journalled into the plate 75 at 77 and passes through. a hole 57 in the mostly-closed side of the housing 30. A pinion 101 is carried on the shaft 71 outside the housing 30 and engages the gear train 102-105, 83-85, the latter three being formed on the wheels 80-82. The housing 30 is recessed to accommodate the gearing, some of which is mounted directly to the housing. Suspension: The body is supported on the truck by a gimbal mounting comprising a collar 110 attached to the housing 30 and a yoke 120 secured to the body, the yoke being pivotted to the collar. Arcuate ends 111, 112 of the collar 110 are trapped below ribs 61, 62 on the housing 30 to retain the collar but allow it limited rotation about a vertical axis relative to the housing. The yoke 120 is pivotted to the collar 110 by projections 127, 128 that fit into recesses 117, 118 in the collar, allowing relative movement about a horizontal axis. The collar 110 and yoke 120 both have the width of the vehicle body to be secured within it; the yoke also has projections 125, 126 that fit into slots 129, 130 in the body. Pairs of resilient fingers 131, 132 depend from each side of the yoke 120 to urge the collar 110 into its intermediate pivottinig position. The locomotive has a similar unpowered truck 21.
