| 20090139737 | CHAIN DRIVEN RECIPROCATING HAMMER WITH WORK PIECE CENTERING AND CLAMPING - In accordance with the present invention, a chain driven reciprocating hammer is disclosed. The chain driven reciprocating hammer includes a chain system for lifting a ram to a drop point. The chain system includes a plurality of sprockets and a chain with at least one mesh link to mesh with the ram. Additionally, the chain driven reciprocating hammer includes an adjustable tandem release sprocket mechanism. Also, the chain driven reciprocating hammer includes a center and clamping mechanism configured to secure a work input. | 06-04-2009 |

DRIVE GEARING ADVANCES RELATIVE TO SOURCE OR POWER | 1 |
| 20110232928 | TRANSMISSION FOR OUTDOOR POWER EQUIPMENT - Outdoor power equipment includes an engine having a throttle and a drive shaft, a driven shaft, a tool coupled to the driven shaft. The engine further includes a transmission coupling the drive and driven shafts and providing a mechanical advantage therebetween. The transmission automatically changes the mechanical advantage in response to torque experienced by the driven shaft. | 09-29-2011 |

WITH MEANS ENGAGED BY PART OF HUMAN OTHER THAN HAND | 1 |
| 20120037386 | ERGONOMIC HAND-HELD POWER TOOL AND METHODS OF USE - An ergonomically enhanced electric power tool is disclosed that incorporates a new type of user grip and control system. This grip and control system is housed in a substantially rigid control-housing sheath, which provides enhanced leverage and control over the drilling process while reducing stress on the user's hand, wrist, and arm. The tool motor is disposed substantially in parallel with the user's wrist, but on a different plane, and eliminates the traditional “pistol” type of power-tool grip. The control-housing sheath contains a grip-controller assembly that allows the user to control most major drill operations within the gauntlet-like control-housing sheath. The inventive concepts described can be applied to myriad hand-held power tools, and a detailed example for a power drill is provided. | 02-16-2012 |

SELF-ACTING ADVANCE AND RETRACTION CYCLE | 1 |
| 20110247847 | DRIVE MECHANISM FOR A RECIPROCATING TOOL - Embodiments of the present invention are directed to a drive apparatus for a reciprocating tool, comprising a housing, a rotatable drive shaft assembly located in the housing, an elongated spindle located in the housing for reciprocating motion, a front bushing in the housing for supporting the front end portion of the spindle, and a wobble drive mechanism comprising a wobble drive shaft connected to the drive shaft assembly, an elongated arm having a lengthwise axis extending upwardly from the wobble drive shaft and including an upper interface for reciprocating the spindle generally in its lengthwise direction during alternating cutting and return strokes, wherein the upper interface connects the arm to the spindle in a manner that prevents translational movement of the spindle relative to the arm in the direction of the arm lengthwise axis, but permits rotational movement thereof in three orthogonal axes. | 10-13-2011 |
