| 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 |
| 20130140052 | ANTI-DRY FIRE MECHANISM - The post driver machine includes a housing, inside of which is a weight which can be lifted by a chain being rotated around a generally elliptical path by a powered sprocket. A catch mechanism is affixed to the chain, and can engage with a weight catch attached to the weight. However, when there is not a post positioned within the post driver, the weight rests at a position too low the weight catch to engage with the catch mechanism. Upon properly inserting a post into the post driver, the post presses upwardly on the weight until the weight catch engages with the catch mechanism to lift the weight. | 06-06-2013 |
| 20160069037 | PILE HAMMER - A pile hammer includes a cylinder, a piston displaceably guided in the cylinder, a striker displaceably guided in the cylinder and disposed underneath the piston in the operating position of the pile hammer, a combustion chamber delimited axially by a face surface of the striker that lies in the interior of the cylinder and by a face surface of the piston, as well as a disengagement apparatus by way of which the piston can be moved in the cylinder, into an upper position, wherein the disengagement apparatus includes a carriage, which is connected with at least one cable, by way of which the carriage is guided to be displaceable on the outside, along the cylinder, wherein a stop that projects outward is disposed on the cylinder and a buffer part is disposed on the carriage, with which part the carriage lies against the stop in an upper end position. | 03-10-2016 |
| 20160097178 | ROPE-SUSPENDED LEADER MAST - A rope-suspended leader mast includes a lower part for accommodating a material to be pile-driven and an upper part for accommodating a diesel pile driver having a fuel feed. The leader mast is provided with at least one securing rope. A fuel feed interrupter interrupts the fuel feed of the diesel pile driver accommodated by the rope-suspended leader mast when the securing rope is tensioned. | 04-07-2016 |

POWER PATHS TO PLURAL TOOLS FROM SINGLE DRIVE | 2 |
| 20150047865 | COMPLEX PNEUMATIC TOOL - A complex pneumatic tool includes: a body section having a main body formed with an internal slide room; a slide member with a predetermined length, the slide member being slidably disposed in the slide room, two ends of the slide member respectively extending out of the body section from the slide room, the slide member being axially reciprocally movable between a first position and a second position under the restriction of the slide room; a first action section disposed at one end of the slide member; and a second action section disposed at the other end of the slide member. The complex pneumatic tool can be conveniently used to facilitate service operation of a vehicle. | 02-19-2015 |
| 20120168190 | DRIVE DEVICE - The invention relates to a drive device for alternatively driving a tool disk ( | 07-05-2012 |

WITH MEANS ENGAGED BY PART OF HUMAN OTHER THAN HAND | 2 |
| 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 |

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 |

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 |

| 20130213678 | DUAL REAMER DRIVER - The disclosure illustrates a dual driver for surgical reamers in which either of a crossbridge and crossbar style reamers are axially inserted in the distal end of a central shaft for the reamer driver. A pair of L shaped grips are adapted to connect and disconnect the different style of reamers by the movement of an external sleeve biased towards the connection position. Movement of the sleeve away from the distal end allows an internal plunger to cam the grips to an open position and urge the appropriate reamer from the tool driver directly in an axial direction. | 08-22-2013 |
