Power-operated device with a cooling facility

A power-operated device having a motor operable at a prescribed voltage level, which comprises:

• a housing for containing the motor and formed with a cavity therein;
• means for developing operating power at the prescribed voltage level;
• means for cooling the motor;
• means for containing together the developing means and the cooling means;
• the containing means configured externally to fit into the cavity;
• means for connecting the developing means to the motor and the cooling means to provide operating power thereto, and
• means for connecting the developing means to an external power source to facilitate operation of the developing means.

A power-operated device having a drive motor operable at a prescribed voltage level normally associated with a cordless mode of operation which comprises:

• a housing formed with a motor chamber for containing the drive motor and formed with a cavity therein configured for receipt of a container which houses a cordless-mode power source;
• means for developing operating power at the prescribed voltage level;
• means for cooling the motor;
• means for containing together the developing means and the cooling means;
• the containing means configured to fit into the cavity interchangeably with the cordless-mode container;
• means for connecting the developing means to the motor and to the cooling means to provide operating power thereto, and
• means for connecting the developing means to an external power source to facilitate operation of the developing means.

A power-operated device having a drive motor, which comprises:

• a housing formed with a motor chamber, a cavity and a portal between the motor chamber and the cavity;
• means for developing operating power at a predetermined voltage level;
• a cooling motor operable at the predetermined voltage level;
• a fan cage attached to and operable by the cooling motor;
• a container for supporting the operating power developing means, the cooling motor and the fan cage;
• the container formed with a portal and configured to be insertable within the cavity with the container portal aligned with the housing portal, and
• means for applying the operating power of the developing means to the cooling motor to facilitate the movement of a cooling medium about the drive motor.
