Publication number: 20090145568Abstract: A method of making a wear and fatigue resistant component of a power tool (e.g., a clutch) includes providing a quantity of base steel and a quantity of alloying elements to be added to the base steel to form a desired alloyed grade of steel. The base steel and alloying elements are combined and melted to produce a molten alloyed steel (e.g., SAE 9310 or AISI M2). The molten alloyed steel is cast using a near-net-shape investment casting process to form a component of a power tool. An edge of the component is pre-radiused. and the component is case hardened after the edge of the component has been pre-radiused. In one implementation, the component is a clutch that has a lifespan of at least twice a lifespan of a second clutch that has not been pre-radiused prior to case hardening.Type: ApplicationFiled: February 9, 2009Publication date: June 11, 2009Applicant: Black & Decker Inc.Inventors: Bimal Kumar Chaterjee, Alan Phillips, John Robert Kriaski, Daniel Paxton wall

Patent number: 7047848Abstract: A process for manufacturing highly wear and fatigue resistant steel components for power tools includes melting and mixing together a readily available base steel and alloying elements. The molten steel is cast into near-net-shape in an investment casting process. This method is cost competitive with forming the same component from steel with fewer alloying elements. In particular, clutch plates for a drill/driver or screw gun can be formed in this manner from a steel containing relatively large amounts of nickel and chromium, such as SAE 9310 steel, or from a steel containing a relatively large total amount of molybdenum and tungsten, such as AISI M2 steel.Type: GrantFiled: February 11, 2003Date of Patent: May 23, 2006Assignee: Portar-Cable/DeltaInventors: Bimal Kumar Chaterjee, Alan Phillips, John Robert Kriaski, Daniel Paxton Wall

Patent number: 6912932Abstract: A depth adjusting system for a screw gun comprises a base supported on the screw gun, an on/off collar removably attached to the base, and an adjusting collar and a depth locator mounted to the on/off collar. The adjusting collar rotates but cannot move axially relative to the on/off collar. Rotation of the adjusting collar causes the depth locator to move axially relative to the on/off collar for adjusting the depth setting. An indexing system is provided between the adjusting collar and the on/off collar for retaining the angular position of the adjusting collar and the depth setting. The on/off collar can be easily attached and detached from the base with a simple axial force applied to the on/off collar.Type: GrantFiled: August 20, 2003Date of Patent: July 5, 2005Assignee: Porter-Cable/DeltaInventors: John Robert Kriaski, Daniel Paxton Wall

Patent number: 6665923Abstract: A clutch specially adapted for a screw gun includes an output clutch and a driving clutch. The output clutch is movable axially to engage the driving clutch. A helical spline arrangement on the driving clutch causes the driving clutch to move axially towards the output clutch a short distance when torque is transferred through the clutch. When the clutch slips and the torque is released, the driving clutch moves axially away from the output clutch a short distance and a gap is created between the output clutch and driving clutch which prevents clashing. Also, a retaining ring is mounted to an input spindle to limit the axial movement of the driving clutch.Type: GrantFiled: August 8, 2001Date of Patent: December 23, 2003Assignee: Porter-Cable/DeltaInventors: Alan Gene Phillips, John Robert Kriaski, Daniel Paxton Wall
