Abstract: A system for sharpening a tool bit in a fixed geometry has a base with a support platform and guide rod attached to and extending from the platform; a fixture including a longitudinal extending body with a plurality of linear bore holes extending through a transverse width of the fixture; and a tool bit support assembly removeably connected to the fixture for receiving the tool bit. In operation, the system provides for a user to insert the guide rod through one of the bore holes in the plurality and to position the tool bit in a fixed orientation for sharpening a free end of the tool bit. By forming the fixture with a specific number of bore holes, each positioned at a precise angle within the fixture, the system provides for the sharpening of the tool bit in a fixed geometry in a way that is consistent, precise, and repeatable.

Abstract: An improved impact power tool for carving and engraving an article comprises an air delivery system operable to communicate with a pressurized air source; a drive assembly operable to receive air from the pressurized air source via the air delivery system; a hand held device in driven communication with the drive assembly; and a housing for storage of the air delivery system and drive assembly. The tool includes an improved valve design, a throttle bias valve, and an air storage tank housed within the housing, and an improved housing construction. The improved valve design and air storage tank enable greater stroke speeds of a work tool over a wider power range while also improving the crispness and speed of the impact reaction time over the entire range. The throttle bias valve is in communication with an additional exhaust path, such that the bias valve allows improved control of the hand held device and improved operation over a wider range of air pressures.

Abstract: An improved power operated tool holder and actuator unit (10) is provided which permits use of conventional, manually operable pivoted dual-leg tools (e.g., pliers, nippers or crimpers) and eliminates the need for specialized tools of this character. The unit (10) includes a tool holder (20) operably coupled with an actuator (18) which can be controlled by a foot switch (14). The holder (20) has upper and lower tool leg clamps (78, 82) which respectively hold the ends (178, 180) of a dual-leg tool (172). The lower leg clamp (82) is coupled via an operator (80) to a pneumatic piston and cylinder assembly (30) controlled by switch (14). In use, a charge of pressurized air delivered to the assembly (30) effects movement of a piston rod (40) which in turn moves leg clamp (82) so as to close the work performing ends (182, 184) of the tool (172).
