  • Patent number: 6912790
    Abstract: A power tool, such as a reciprocating saw, including a spindle for supporting a tool element, a body defining a pivot axis and housing a motor and a drive mechanism driven by the motor, the drive mechanism driving the spindle, the body having a forward end supporting the spindle and a rearward end, and a grip connected to the rearward end of the body for pivoting movement about the pivot axis. The reciprocating saw may include a locking assembly for locking the grip in a pivoted position relative to the body and a switch assembly at least partially supported on the grip. The switch assembly is preferably inoperable when the locking assembly is in an unlocked condition, and the locking assembly preferably cannot be moved to the unlocked condition when the switch assembly is in an operating condition. Also, the reciprocating saw may include a grip portion provided by the body and engageable by the operator's other hand.

  • Patent number: 6249979
    Abstract: An orbital reciprocating saw comprising a housing, a motor, a spindle movably supported within said housing and having a front end adapted to support a saw blade, a reciprocating drive assembly, an orbital drive assembly connected to said spindle to selectively drive the saw blade in an orbital path, an orbital adjustment assembly connected to the orbital drive assembly to adjust the orbital path of the saw blade, and an adjustable shoe assembly. The orbital drive assembly includes an eccentric cam member removably supported on the motor drive shaft and engageable with the spindle to cause orbital movement of the saw blade upon rotation of the motor drive shaft. The orbital adjustment assembly selectively disengages the spindle from the cam member during at least a portion of the rotation of the cam member to change the orbital path of the saw blade.

  • Patent number: 6212781
    Abstract: A reciprocating saw including a housing, a spindle mounted for reciprocation relative to the housing and having a front end adapted to support a saw blade, the spindle being movable through a cutting stroke and a return stroke, a motor for moving the spindle in a reciprocating fashion, and a reciprocating member interconnecting the motor with the spindle. The motor and the spindle define a drive force path from the motor to the spindle and passing through drive force bearing components of the reciprocating saw, and wherein at least part of the reciprocating member is in the drive force path. The reciprocating member is configured to counterbalance the spindle. A pivot body interconnects the spindle with the motor. A shock absorber is operatively positioned between the motor and the front end of the spindle, and is at least partially mounted within the spindle.

  • Patent number: 6209208
    Abstract: A reciprocating tool (e.g., a reciprocating saw) comprising a housing, a spindle mounted for reciprocating movement within the housing and having an end adapted to receive a saw blade, and a blade clamp mechanism connected to the spindle and adapted to attach a saw blade to the spindle. The blade clamp mechanism includes an actuating member mounted on the end of the spindle and capable of moving relative to the spindle between an engaged position and a disengaged position, and a locking member operatively associated with the actuating member and moveable relative to the spindle between a locked position that locks a saw blade to the spindle and an unlocked position that releases the saw blade.
