  • Guide Foot for an Oscillating Power Tool
    Publication number: 20180272517
    Abstract: A guide member for an oscillating power tool includes an attachment portion configured to be removably attached to a housing of the power tool and a guide portion that extends from the attachment portion. The guide portion includes a leading edge, a trailing edge, and a guide surface. When the attachment portion is attached to the housing of the power tool, the guide portion is configured to extend beyond the housing in a first direction to position the leading edge portion a predetermined distance apart from the oscillation axis, the predetermined distance being greater than a distance that an accessory tool attached to the power tool extends.

  • Counterbalance for eccentric shafts
    Patent number: 9770817
    Abstract: A power tool includes a housing, a motor having a motor output shaft and located within the housing, the motor being configured to rotate the motor output shaft about a first axis, a drive component having (i) a body attached to the motor output shaft, and (ii) an output drive pin attached to the body, the output drive pin defining a second axis which is offset from the first axis, the body being caused to rotate about the first axis in response to rotation of the motor output shaft about the first axis, and the output drive pin being caused to be eccentrically driven in response to rotation of the body about the first axis, and further the body having a hub and a counterbalance arrangement attached to the hub, the counterbalance arrangement being positioned and configured to offset forces generated by the output drive pin when eccentrically driven, a linkage configured to oscillate in response to the output drive pin being eccentrically driven, and a tool mount configured to oscillate in response to oscillat
