Speedometer for toy vehicles

Abstract

Abstract APPARATUS FOR INDICATING THE SPEED OF TOY VEHICLES MOVING ALONG A TRACK COMPRISING AN IMPULSE VANE WHICH IS BIASED BY A SPRING TO A POSITION OVER THE TRACK, SO THAT THE SPEED OF A TOY VEHICLE HITTING THE VANE DETERMINES HOW FAR IT WILL BE PIVOTED AGAINST THE SPRING FORCE. THE VANE TURNS AN INDICATOR WHEEL WITH A POINTER EXTENDING FROM WHICH MOVES OVER A SCALE TO INDICATE THE SPEED OF THE VEHICLE. A PAWL WHICH ENGAGES RATCHETS ON THE INDICATOR WHEEL RETAINS IT AT THE FIRST POSITION TO WHICH IT HAS BEEN MOVED BY THE VANE. A RESETTING LEVER IS POSITIONED UPTRACK FROM THE VANE SO IT IS HIT BY A VEHICLE PRIOR TO THE VEHICLE HITTING THE VANE, THE RESETTING LEVER RELEASING THE INDICATING WHEEL FOR THE PAWL, SO THE POINTER RETURNS TO A ZERO POSITION. A TRACK SECTION OVER WHICH THE VANE EXTENDS IS BANKED TOWARD THE VANE TO MAKE SURE THAT BOTH WIDE AND NARROW VEHICLES HIT APPROXIMATELY THE SAME PORTION OF THE VANE, TO INCREASE ACCURACY.
