A power module which when plugged into an open compartment in the body of a motorless toy vehicle acts to motorize the vehicle, the compartment being disposed above a coupling gear which is operatively linked to a wheel or other means to propel the vehicle. Pivotally supported within the case of the module is a DC motor and a gear assembly having attached thereto a control lever. A battery supply housed in the case is connected to the motor through a normally open switch that closes to power the motor when the control lever which normally is in a neutral mode, is shifted either to a forward mode in which the assembly is then inclined to drive the vehicle in the forward direction, or to a reverse mode in which the assembly is then oppositely inclined to drive the vehicle in the reverse direction. The assembly includes a worm gear on the motor shaft and a pair of drive pinions engaging the worm gear on either side thereof whereby the pinions are caused to rotate concurrently in opposite directions. In the neutral mode, neither pinion engages the coupling gear and the vehicle is then free wheeling. In the forward mode, the coupling gear is engaged by only one drive pinion to cause forward motion of the vehicle, and in the reverse mode, the coupling gear is engaged only by the other drive pinion to cause reverse motion of the vehicle.

A power module adapted to be installed in an open compartment in the body of a motorless toy vehicle to drive the vehicle in a desired direction, said compartment being disposed above a coupling gear operatively linked to a drive wheel, the module comprising: A. a case having a base and housing a battery supply; and B. a DC motor and gear assembly pivotally supported within the case having a control lever attached thereto which normally is positioned in a neutral non-driving mode, the lever being selectively shiftable either to a forward mode for driving the vehicle in the forward direction in which the assembly is then inclined with respect to the neutral mode, or to a reverse mode for driving the vehicle in the opposite direction in which the assembly is then oppositely inclined, said assembly being provided with a worm gear on a shaft of the motor and a pair of drive pinions engaging the worm gear on either side thereof, said pinions being positioned at an opening in said base adjacent said coupling gear, whereby when the motor is connected to said supply, the pinions are caused to rotate concurrently in opposite directions, only one of said pinions engaging the coupling gear in the forward mode and only the other pinion engaging the coupling gear in the reverse mode, both pinions being disengaged from the coupling gear in the neutral mode.
