The magazine has a housing configured to be rotatably attachable to the power tool housing. An advancing mechanism is received in the magazine housing, and is configured to advance a strip of collated fasteners into position to be driven by the power tool. An indexing ring has a plurality of recesses and is configured to be non-rotatably attached to the power tool housing. A detent is biased to removably engage one of the plurality of recesses, and is configured to be non-rotatably attached to the magazine housing.

Publication number: 20140274548Abstract: A clutch for a power tool includes an adjustment ring configured to move axially relative to the housing while being rotated relative to the housing. A spring retainer is disposed axially rearward of the adjustment ring. The spring retainer is coupled for rotation together with the adjustment ring and configured to remain substantially axially stationary relative to the housing when rotated. A spring is disposed between the adjustment ring and the spring retainer. A clutch face is coupled to a portion of the transmission. A locking member is disposed between the spring retainer and the clutch face. The locking member is configured to transfer a holding force exerted by the spring to the clutch face. Rotation and axial movement of the adjustment ring alters the holding force exerted by the spring. When an amount of output torque exceeds the holding force, torque transmission to the output spindle is effectively interrupted.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Applicant: Black & Decker Inc.Inventors: Joseph P.

Publication number: 20140102742Abstract: A power tool includes a housing, a motor, an output member driven by the motor, and a reaming attachment coupled to the output member. The reaming attachment has a front end portion selectively driven in rotation by the output member to drive a fastener into a workpiece, and a reaming portion selectively driven in rotation by the output member to remove material from an end surface of a conduit. A rotational motion sensor in the housing is operable to detect rotational motion of the housing about an axis. A controller receives a signal indicative of rotational motion from the sensor, determines a direction of the rotational motion of the housing, and drives the motor in a direction corresponding to the direction of rotational motion of the housing.Type: ApplicationFiled: December 17, 2013Publication date: April 17, 2014Inventors: Scott J. ESHLEMAN, Craig A. SCHELL, Andrew J. SEMAN, JR., Daniel PUZIO, Danielle C. BROTTO, Joseph P. KELLEHER, Oleksiy P. SERGYEYENKO

Patent number: 8678725Abstract: A bit retaining system for a rotary tool or device such as a router is disclosed. The bit retaining system may include a collet assembly and a control assembly. The collet assembly may include a spindle, a collet adapted to receive the bit, and a collet nut. The collet assembly may further include a collet gear mounted on the collet nut and/or a spindle gear mounted on the spindle. The control assembly selectively engages the collet assembly to drive the collet nut and/or secure the spindle in a fixed position, preventing its rotation. In operation, a hand tool is utilized to engage the control assembly. This configuration enables a user to capture and release the rotary tool bit using one hand.Type: GrantFiled: February 16, 2010Date of Patent: March 25, 2014Assignee: Black & Decker Inc.Inventors: Warren A. Ceroll, Gregory K. Griffin, Steven D. McDaniel, Craig A. Schell, Robert S. Gehret, Joseph P. Kelleher

Publication number: 20130284471Abstract: A power tool includes a housing, an output member that rotates about a longitudinal axis, and a motor drivably connected to the output member. A rotational motion sensor is arranged in the housing and operable to detect a user input that includes a rotational motion of the housing in a desired rotational direction about the longitudinal axis of the output member. A controller is configured to receive a first input indicative of a user-desired rotational motion of the output member, and a second input, from the rotational motion sensor, indicative of an actual rotational motion of the power tool. The controller determines a user-desired rotational direction of the output member about the axis from the first input, determines an actual rotational direction of the housing about the axis from the second input, and causes the motor to drive the output member to simulate ratcheting movement in the user-desired rotational direction.Type: ApplicationFiled: January 31, 2013Publication date: October 31, 2013Inventors: Scott J. Eshleman, Craig A. Schell, Andrew E. Seman, JR., Daniel Puzio, Daniele C. Brotto, Joseph P. Kelleher, Sankarshan Murthy

Patent number: 8418778Abstract: An improved method is provided for operating a power tool. The method includes: monitoring rotational motion of the power tool about an axis using a rotational motion sensor disposed in the power tool; determining a direction of the rotational motion about the axis; and driving the output member in a direction defined by the detected rotational motion of the tool, where the output member is driven by a motor residing in the power tool. Thus, the output member is drive clockwise when the rotational motion of the tool is clockwise about the axis and the output member is drive counter-clockwise when the rotational motion of the tool is counter-clockwise about the axis.Type: GrantFiled: February 24, 2012Date of Patent: April 16, 2013Assignee: Black & Decker Inc.Inventors: Scott Eshleman, Craig Schell, Andrew E.

Publication number: 20130000935Abstract: The present invention is directed toward a shield assembly for a handheld tool device such as an angle grinder. The shield assembly is selectively repositionable with respect to the cutting tool. A lock mechanism secures the shield assembly in discrete rotational positions relative to the cutting tool. The shield assembly includes a guard member and a bumper member, and an alignment feature configured to align the relative positions of guard member and the bumper member, thereby positing the members in a predetermined relative orientation. With this configuration, the shield assembly is selectively repositionable via a “hands-free” mechanism that permits a user to adjust the position of the shield assembly by simply contacting the shield assembly against a work surface.Type: ApplicationFiled: June 27, 2012Publication date: January 3, 2013Applicant: BLACK & DECKER INC.Inventors: Joseph P.
