Abstract: A preferred embodiment of a rotary tool reciprocating motion conversion attachment for a rotary power hand tool is described which is configured to be attached to a nose portion of the hand tool housing. The attachment has a rotary drive train in a housing that is connectable to the output shaft of the hand tool, the drive train driving a barrel cam having an exterior cam groove. A cam follower rides in the cam groove and produces reciprocating motion, with the cam follower being part of a cam follower assembly to which an implement holder is attached. The preferred embodiment has a cam groove configuration which causes the implement holder to move slower during a cutting stroke and faster during a return stroke, thereby tending to optimize the operation of the cutting implement. The preferred embodiment also includes a planetary gear set for reducing the rotational speed of the hand tool output shaft to reduce the speed of reciprocation of the attachment.

Abstract: A transportable pressurized coffee maker adapted to be used in and mounted to an automobile includes a coffee cup to receive brew which can be secured in tandem with the brewing chamber to prevent spills while driving. Safety features include temperature regulation, pressure release, interlocking safety cap, non-pressurized brewing chamber and a cool-to-touch outer shell. This coffee making apparatus also provides a high heat transfer immersion heating element compatible with the nominal 12 volt d.c. electrical system of most automobiles. This coffee making apparatus provides a sealable unit which can be operated while the automobile is in motion.
