20090101377BREAKING MACHINE - A breaking apparatus (04-23-2009
20090139737CHAIN 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
20130140052ANTI-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
173140000 DRIVE GEARING ADVANCES RELATIVE TO SOURCE OR POWER 1
20110232928TRANSMISSION 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

20120168190DRIVE DEVICE - The invention relates to a drive device for alternatively driving a tool disk (07-05-2012
173030000 WITH MEANS ENGAGED BY PART OF HUMAN OTHER THAN HAND 1
20120037386ERGONOMIC 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
173045000 WITH MEANS TO SPACE AXIS OF TOOL ADVANCE RELATIVE TO PRIOR POSITION 1
20130213678DUAL 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
173019000 SELF-ACTING ADVANCE AND RETRACTION CYCLE 1
20110247847DRIVE 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
