  • Patent number: 5259914
    Abstract: The present invention is a portable vehicle adhesive remover having (a) a motor unit assembled inside a housing including a throttler, a rotor and a gear assembly where the motor unit has an elongated spindle extending out from the top opening of the housing; (b) an extending shank having a proximal end attached to the elongated spindle of the motor unit and a distal end; and (c) an eraser unit attached to the distal end of the extending shank including a resilient eraser member and a disc member embedded in the eraser member. When the eraser unit and the motor unit are attached and a high pressure compressed air is sent into the bottom opening of the housing, the compressed air will be gushed into the rotor by the throttler assembly, which in turn will drive the eraser unit through the gear assembly and cause the resilient eraser member to rotate at a high speed.
