Abstract: A drawing device adapted to produce line drawings or sketches on a transparent screen on top of a case partly filled with a powder that adheres slightly to the undersurface of the screen to render it opaque. Disposed within the case are transverse and longitudinal rods operatively coupled to respective control knobs, one of which, when turned, causes the longitudinal rod to shift toward either side of the case, the other of which, when turned causes the transverse rod to shift to either end of the case. Supported at the intersection of the rods is an indexable stylus turret and carrier assembly whose carrier is slidably supported on the transverse rod and whose stylus turret which is received within the carrier, is slidably supported on the longitudinal rod whereby the position occupied by the assembly is determined by the point of intersection.

Abstract: A hand-propelled toy airplane, locomotive or other wheeled vehicle for pre-school children having a handle making it possible for a player to push the vehicle along a surface. The vehicle is provided with one or more lights whose bulbs are connected to a battery supply through a handle switch that is actuated only when the player grasps the handle to turn on the lights. Operatively coupled to the axle of a wheel set is an interrupter switch connected in series with the handle switch, the circuit arrangement being such that when the handle switch is actuated, at least one light goes one, and when the vehicle is pushed along the surface, the actuated interrupter switch then causes the lights to turn on intermittently to produce a blinking effect at a rate depending on how fast the vehicle is being propelled. When the handle switch is released by the player, the battery supply is disconnected from the bulbs, so that no power is drained from the supply when the toy is not in use.
