Dental stain remover

Image Number 4 for United States Patent #4183140.

A dental stain remover apparatus for removing stains from teeth comprising a drive casing with a removable handle mounted to the drive casing at an angle to the axis of the drive casing, the drive casing forming a chamber which receives a motor and defining a body, nose section, base and cap switch assembly. Batteries are mounted in the handle casing and are electrically connected to the motor by means of the handle casing and a lever switch which extends from the cap switch assembly in the same direction as the handle casing. The motor drives a shaft which is in turn connected to a spindle holding a polishing cup configured to hold the polishing dentifrice. The drive casing and handle are one piece assemblies and are sealed to prevent entrance of foreign material by screwing the handle casing to the drive casing.
