ELECTRICALLY DRIVEN VEHICLES
First Claim
1. In a self-propelled electric vehicle having a frame, driving wheels, an electric motor operatively connected to said driving wheels, a heavy duty battery, an electrical connection from the battery to the motor, the improvement of a pair of longitudinally spaced supports for said battery mounted on said frame, said supports extending laterally outwardly and away from said frame, a reinforced case for said battery, bracket means secured to each end of said case for supporting said case and the battery held thereby on said pair of laterally extending supports when the battery is in operative position a bumper secured to the vehicle frame against which the battery case rests when in operative position, a fixed stop on each of said supports in laterally spaced relation to the bumper permitting vertical movement of said battery case relative to said support to permit removal of said battery but preventing horizontal movement of said battery case relative to said support at all other times.
